Ecology

Ecology is the natural science of the relationships among living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere levels. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and is the study of abundance, biomass, and distribution of organisms in the context of the environment. It encompasses life processes, interactions, and adaptations; movement of materials and energy through living communities; successional development of ecosystems; cooperation, competition, and predation within and between species; and patterns of biodiversity and its effect on ecosystem processes. Ecology has practical applications in conservation biology, wetland management, natural resource management (agroecology, agriculture, forestry, agroforestry, fisheries, mining, tourism), urban planning (urban ecology), community health, economics, basic and applied science, and human social interaction (human ecology). The word ecology was coined in 1866 by the German scientist Ernst Haeckel. The science of ecology as we know it today began with a group of American botanists in the 1890s. Evolutionary concepts relating to adaptation and natural selection are cornerstones of modern ecological theory. Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living (abiotic) components of their environment. Ecosystem processes, such as primary production, nutrient cycling, and niche construction, regulate the flux of energy and matter through an environment. Ecosystems have biophysical feedback mechanisms that moderate processes acting on living (biotic) and abiotic components of the planet. Ecosystems sustain life-supporting functions and provide ecosystem services like biomass production (food, fuel, fiber, and medicine), the regulation of climate, global biogeochemical cycles, water filtration, soil formation, erosion control, flood protection, and many other natural features of scientific, historical, economic, or intrinsic value. Levels, scope, and scale of organization The scope of ecology contains a wide array of interacting levels of organization spanning micro-level (e.g., cells) to a planetary scale (e.g., biosphere) phenomena. Ecosystems, for example, contain abiotic resources and interacting life forms (i.e., individual organisms that aggregate into populations which aggregate into distinct ecological communities). Because ecosystems are dynamic and do not necessarily follow a linear successional route, changes might occur quickly or slowly over thousands of years before specific forest successional stages are brought about by biological processes. An ecosystem's area can vary greatly, from tiny to vast. A single tree is of little consequence to the classification of a forest ecosystem, but is critically relevant to organisms living in and on it. Several generations of an aphid population can exist over the lifespan of a single leaf. Each of those aphids, in turn, supports diverse bacterial communities. The nature of connections in ecological communities cannot be explained by knowing the details of each species in isolation, because the emergent pattern is neither revealed nor predicted until the ecosystem is studied as an integrated whole. Some ecological principles, however, do exhibit collective properties where the sum of the components explain the properties of the whole, such as birth rates of a population being equal to the sum of individual births over a designated time frame. The main subdisciplines of ecology, population (or community) ecology and ecosystem ecology, exhibit a difference not only in scale but also in two contrasting paradigms in the field. The former focuses on organisms' distribution and abundance, while the latter focuses on materials and energy fluxes. Hierarchy The scale of ecological dynamics can operate like a closed system, such as aphids migrating on a single tree, while at the same time remaining open about broader scale influences, such as atmosphere or climate. Hence, ecologists classify ecosystems hierarchically by analyzing data collected from finer scale units, such as vegetation associations, climate, and soil types, and integrate this information to identify emergent patterns of uniform organization and processes that operate on local to regional, landscape, and chronological scales. To structure the study of ecology into a conceptually manageable framework, the biological world is organized into a nested hierarchy, ranging in scale from genes, to cells, to tissues, to organs, to organisms, to species, to populations, to guilds, to communities, to ecosystems, to biomes, and up to the level of the biosphere. This framework forms a panarchy and exhibits non-linear behaviors; this means that "effect and cause are disproportionate, so that small changes to critical variables, such as the number of nitrogen fixers, can lead to disproportionate, perhaps irreversible, changes in the system properties." Biodiversity Biodiversity (an abbreviation of "biological diversity") describes the diversity of life from genes to ecosystems and spans every level of biological organization. The term has several interpretations, and there are many ways to index, measure, characterize, and represent its complex organization. Biodiversity includes species diversity, ecosystem diversity, and genetic diversity and scientists are interested in the way that this diversity affects the complex ecological processes operating at and among these respective levels. Biodiversity plays an important role in ecosystem services which by definition maintain and improve human quality of life. Conservation priorities and management techniques require different approaches and considerations to address the full ecological scope of biodiversity. Natural capital that supports populations is critical for maintaining ecosystem services and species migration (e.g., riverine fish runs and avian insect control) has been implicated as one mechanism by which those service losses are experienced. An understanding of biodiversity has practical applications for species and ecosystem-level conservation planners as they make management recommendations to consulting firms, governments, and industry. Habitat The habitat of a species describes the environment over which a species is known to occur and the type of community that is formed as a result. More specifically, "habitats can be defined as regions in environmental space that are composed of multiple dimensions, each representing a biotic or abiotic environmental variable; that is, any component or characteristic of the environment related directly (e.g. forage biomass and quality) or indirectly (e.g. elevation) to the use of a location by the animal." For example, a habitat might be an aquatic or terrestrial environment that can be further categorized as a montane or alpine ecosystem. Habitat shifts provide important evidence of competition in nature where one population changes relative to the habitats that most other individuals of the species occupy. For example, one population of a species of tropical lizard (Tropidurus hispidus) has a flattened body relative to the main populations that live in open savanna. The population that lives in an isolated rock outcrop hides in crevasses where its flattened body offers a selective advantage. Habitat shifts also occur in the developmental life history of amphibians, and in insects that transition from aquatic to terrestrial habitats. Biotope and habitat are sometimes used interchangeably, but the former applies to a community's environment, whereas the latter applies to a species' environment. Niche Definitions of the niche date back to 1917, but G. Evelyn Hutchinson made conceptual advances in 1957 by introducing a widely adopted definition: "the set of biotic and abiotic conditions in which a species is able to persist and maintain stable population sizes." The ecological niche is a central concept in the ecology of organisms and is sub-divided into the fundamental and the realized niche. The fundamental niche is the set of environmental conditions under which a species is able to persist. The realized niche is the set of environmental plus ecological conditions under which a species persists. The Hutchinsonian niche is defined more technically as a "Euclidean hyperspace whose dimensions are defined as environmental variables and whose size is a function of the number of values that the environmental values may assume for which an organism has positive fitness." Biogeographical patterns and range distributions are explained or predicted through knowledge of a species' traits and niche requirements. Species have functional traits that are uniquely adapted to the ecological niche. A trait is a measurable property, phenotype, or characteristic of an organism that may influence its survival. Genes play an important role in the interplay of development and environmental expression of traits. Resident species evolve traits that are fitted to the selection pressures of their local environment. This tends to afford them a competitive advantage and discourages similarly adapted species from having an overlapping geographic range. The competitive exclusion principle states that two species cannot coexist indefinitely by living off the same limiting resource; one will always out-compete the other. When similarly adapted species overlap geographically, closer inspection reveals subtle ecological differences in their habitat or dietary requirements. Some models and empirical studies, however, suggest that disturbances can stabilize the co-evolution and shared niche occupancy of similar species inhabiting species-rich communities. The habitat plus the niche is called the ecotope, which is defined as the full range of environmental and biological variables affecting an entire species. Niche construction Organisms are subject to environmental pressures, but they also modify their habitats. The regulatory feedback between organisms and their environment can affect conditions from local (e.g., a beaver pond) to global scales, over time and even after death, such as decaying logs or silica skeleton deposits from marine organisms. The process and concept of ecosystem engineering are related to niche construction, but the former relates only to the physical modifications of the habitat whereas the latter also considers the evolutionary implications of physical changes to the environment and the feedback this causes on the process of natural selection. Ecosystem engineers are defined as: "organisms that directly or indirectly modulate the availability of resources to other species, by causing physical state changes in biotic or abiotic materials. In so doing they modify, maintain and create habitats." The ecosystem engineering concept has stimulated a new appreciation for the influence that organisms have on the ecosystem and evolutionary process. The term "niche construction" is more often used in reference to the under-appreciated feedback mechanisms of natural selection imparting forces on the abiotic niche. An example of natural selection through ecosystem engineering occurs in the nests of social insects, including ants, bees, wasps, and termites. There is an emergent homeostasis or homeorhesis in the structure of the nest that regulates, maintains and defends the physiology of the entire colony. Termite mounds, for example, maintain a constant internal temperature through the design of air-conditioning chimneys. The structure of the nests themselves is subject to the forces of natural selection. Moreover, a nest can survive over successive generations, so that progeny inherit both genetic material and a legacy niche that was constructed before their time. Biome Biomes are larger units of organization that categorize regions of the Earth's ecosystems, mainly according to the structure and composition of vegetation. There are different methods to define the continental boundaries of biomes dominated by different functional types of vegetative communities that are limited in distribution by climate, precipitation, weather, and other environmental variables. Biomes include tropical rainforest, temperate broadleaf and mixed forest, temperate deciduous forest, taiga, tundra, hot desert, and polar desert. Other researchers have recently categorized other biomes, such as the human and oceanic microbiomes. To a microbe, the human body is a habitat and a landscape. Microbiomes were discovered largely through advances in molecular genetics, which have revealed a hidden richness of microbial diversity on the planet. The oceanic microbiome plays a significant role in the ecological biogeochemistry of the planet's oceans. Biosphere The largest scale of ecological organization is the biosphere: the total sum of ecosystems on the planet. Ecological relationships regulate the flux of energy, nutrients, and climate all the way up to the planetary scale. For example, the dynamic history of the planetary atmosphere's CO2 and O2 composition has been affected by the biogenic flux of gases coming from respiration and photosynthesis, with levels fluctuating over time in relation to the ecology and evolution of plants and animals. Ecological theory has also been used to explain self-emergent regulatory phenomena at the planetary scale: for example, the Gaia hypothesis is an example of holism applied in ecological theory. The Gaia hypothesis states that there is an emergent feedback loop generated by the metabolism of living organisms that maintains the core temperature of the Earth and atmospheric conditions within a narrow self-regulating range of tolerance. Population ecology Population ecology studies the dynamics of species populations and how these populations interact with the wider environment. A population consists of individuals of the same species that live, interact, and migrate through the same niche and habitat. A primary law of population ecology is the Malthusian growth model which states, "a population will grow (or decline) exponentially as long as the environment experienced by all individuals in the population remains constant." Simplified population models usually starts with four variables: death, birth, immigration, and emigration. An example of an introductory population model describes a closed population, such as on an island, where immigration and emigration does not take place. Hypotheses are evaluated with reference to a null hypothesis which states that random processes create the observed data. In these island models, the rate of population change is described by: where N is the total number of individuals in the population, b and d are the per capita rates of birth and death respectively, and r is the per capita rate of population change. Using these modeling techniques, Malthus' population principle of growth was later transformed into a model known as the logistic equation by Pierre Verhulst: where N(t) is the number of individuals measured as biomass density as a function of time, t, r is the maximum per-capita rate of change commonly known as the intrinsic rate of growth, and is the crowding coefficient, which represents the reduction in population growth rate per individual added. The formula states that the rate of change in population size will grow to approach equilibrium, where, when the rates of increase and crowding are balanced, . A common, analogous model fixes the equilibrium, as K, which is known as the "carrying capacity." Population ecology builds upon these introductory models to further understand demographic processes in real study populations. Commonly used types of data include life history, fecundity, and survivorship, and these are analyzed using mathematical techniques such as matrix algebra. The information is used for managing wildlife stocks and setting harvest quotas. In cases where basic models are insufficient, ecologists may adopt different kinds of statistical methods, such as the Akaike information criterion, or use models that can become mathematically complex as "several competing hypotheses are simultaneously confronted with the data." Metapopulations and migration The concept of metapopulations was defined in 1969 as "a population of populations which go extinct locally and recolonize". Metapopulation ecology is another statistical approach that is often used in conservation research. Metapopulation models simplify the landscape into patches of varying levels of quality, and metapopulations are linked by the migratory behaviours of organisms. Animal migration is set apart from other kinds of movement because it involves the seasonal departure and return of individuals from a habitat. Migration is also a population-level phenomenon, as with the migration routes followed by plants as they occupied northern post-glacial environments. Plant ecologists use pollen records that accumulate and stratify in wetlands to reconstruct the timing of plant migration and dispersal relative to historic and contemporary climates. These migration routes involved an expansion of the range as plant populations expanded from one area to another. There is a larger taxonomy of movement, such as commuting, foraging, territorial behavior, stasis, and ranging. Dispersal is usually distinguished from migration because it involves the one-way permanent movement of individuals from their birth population into another population. In metapopulation terminology, migrating individuals are classed as emigrants (when they leave a region) or immigrants (when they enter a region), and sites are classed either as sources or sinks. A site is a generic term that refers to places where ecologists sample populations, such as ponds or defined sampling areas in a forest. Source patches are productive sites that generate a seasonal supply of juveniles that migrate to other patch locations. Sink patches are unproductive sites that only receive migrants; the population at the site will disappear unless rescued by an adjacent source patch or environmental conditions become more favorable. Metapopulation models examine patch dynamics over time to answer potential questions about spatial and demographic ecology. The ecology of metapopulations is a dynamic process of extinction and colonization. Small patches of lower quality (i.e., sinks) are maintained or rescued by a seasonal influx of new immigrants. A dynamic metapopulation structure evolves from year to year, where some patches are sinks in dry years and are sources when conditions are more favorable. Ecologists use a mixture of computer models and field studies to explain metapopulation structure. Community ecology Community ecology is the study of the interactions among a collection of species that inhabit the same geographic area. Community ecologists study the determinants of patterns and processes for two or more interacting species. Research in community ecology might measure species diversity in grasslands in relation to soil fertility. It might also include the analysis of predator-prey dynamics, competition among similar plant species, or mutualistic interactions between crabs and corals. Ecosystem ecology Ecosystems may be habitats within biomes that form an integrated whole and a dynamically responsive system having both physical and biological complexes. Ecosystem ecology is the science of determining the fluxes of materials (e.g. carbon, phosphorus) between different pools (e.g., tree biomass, soil organic material). Ecosystem ecologists attempt to determine the underlying causes of these fluxes. Research in ecosystem ecology might measure primary production (g C/m^2) in a wetland in relation to decomposition and consumption rates (g C/m^2/y). This requires an understanding of the community connections between plants (i.e., primary producers) and the decomposers (e.g., fungi and bacteria). The underlying concept of an ecosystem can be traced back to 1864 in the published work of George Perkins Marsh ("Man and Nature"). Within an ecosystem, organisms are linked to the physical and biological components of their environment to which they are adapted. Ecosystems are complex adaptive systems where the interaction of life processes form self-organizing patterns across different scales of time and space. Ecosystems are broadly categorized as terrestrial, freshwater, atmospheric, or marine. Differences stem from the nature of the unique physical environments that shapes the biodiversity within each. A more recent addition to ecosystem ecology are technoecosystems, which are affected by or primarily the result of human activity. Food webs A food web is the archetypal ecological network. Plants capture solar energy and use it to synthesize simple sugars during photosynthesis. As plants grow, they accumulate nutrients and are eaten by grazing herbivores, and the energy is transferred through a chain of organisms by consumption. The simplified linear feeding pathways that move from a basal trophic species to a top consumer is called the food chain. Food chains in an ecological community create a complex food web. Food webs are a type of concept map that is used to illustrate and study pathways of energy and material flows. Empirical measurements are generally restricted to a specific habitat, such as a cave or a pond, and principles gleaned from small-scale studies are extrapolated to larger systems. Feeding relations require extensive investigations, e.g. into the gut contents of organisms, which can be difficult to decipher, or stable isotopes can be used to trace the flow of nutrient diets and energy through a food web. Despite these limitations, food webs remain a valuable tool in understanding community ecosystems. Food webs illustrate important principles of ecology: some species have many weak feeding links (e.g., omnivores) while some are more specialized with fewer stronger feeding links (e.g., primary predators). Such linkages explain how ecological communities remain stable over time and eventually can illustrate a "complete" web of life. The disruption of food webs may have a dramatic impact on the ecology of individual species or whole ecosystems. For instance, the replacement of an ant species by another (invasive) ant species has been shown to affect how elephants reduce tree cover and thus the predation of lions on zebras. Trophic levels A trophic level (from Greek troph, τροφή, trophē, meaning "food" or "feeding") is "a group of organisms acquiring a considerable majority of its energy from the lower adjacent level (according to ecological pyramids) nearer the abiotic source." Links in food webs primarily connect feeding relations or trophism among species. Biodiversity within ecosystems can be organized into trophic pyramids, in which the vertical dimension represents feeding relations that become further removed from the base of the food chain up toward top predators, and the horizontal dimension represents the abundance or biomass at each level. When the relative abundance or biomass of each species is sorted into its respective trophic level, they naturally sort into a 'pyramid of numbers'. Species are broadly categorized as autotrophs (or primary producers), heterotrophs (or consumers), and Detritivores (or decomposers). Autotrophs are organisms that produce their own food (production is greater than respiration) by photosynthesis or chemosynthesis. Heterotrophs are organisms that must feed on others for nourishment and energy (respiration exceeds production). Heterotrophs can be further sub-divided into different functional groups, including primary consumers (strict herbivores), secondary consumers (carnivorous predators that feed exclusively on herbivores), and tertiary consumers (predators that feed on a mix of herbivores and predators). Omnivores do not fit neatly into a functional category because they eat both plant and animal tissues. It has been suggested that omnivores have a greater functional influence as predators because compared to herbivores, they are relatively inefficient at grazing. Trophic levels are part of the holistic or complex systems view of ecosystems. Each trophic level contains unrelated species that are grouped together because they share common ecological functions, giving a macroscopic view of the system. While the notion of trophic levels provides insight into energy flow and top-down control within food webs, it is troubled by the prevalence of omnivory in real ecosystems. This has led some ecologists to "reiterate that the notion that species clearly aggregate into discrete, homogeneous trophic levels is fiction." Nonetheless, recent studies have shown that real trophic levels do exist, but "above the herbivore trophic level, food webs are better characterized as a tangled web of omnivores." Keystone species A keystone species is a species that is connected to a disproportionately large number of other species in the food-web. Keystone species have lower levels of biomass in the trophic pyramid relative to the importance of their role. The many connections that a keystone species holds means that it maintains the organization and structure of entire communities. The loss of a keystone species results in a range of dramatic cascading effects (termed trophic cascades) that alters trophic dynamics, other food web connections, and can cause the extinction of other species. The term keystone species was coined by Robert Paine in 1969 and is a reference to the keystone architectural feature as the removal of a keystone species can result in a community collapse just as the removal of the keystone in an arch can result in the arch's loss of stability. Sea otters (Enhydra lutris) are commonly cited as an example of a keystone species because they limit the density of sea urchins that feed on kelp. If sea otters are removed from the system, the urchins graze until the kelp beds disappear, and this has a dramatic effect on community structure. Hunting of sea otters, for example, is thought to have led indirectly to the extinction of the Steller's sea cow (Hydrodamalis gigas). While the keystone species concept has been used extensively as a conservation tool, it has been criticized for being poorly defined from an operational stance. It is difficult to experimentally determine what species may hold a keystone role in each ecosystem. Furthermore, food web theory suggests that keystone species may not be common, so it is unclear how generally the keystone species model can be applied. Complexity Complexity is understood as a large computational effort needed to piece together numerous interacting parts exceeding the iterative memory capacity of the human mind. Global patterns of biological diversity are complex. This biocomplexity stems from the interplay among ecological processes that operate and influence patterns at different scales that grade into each other, such as transitional areas or ecotones spanning landscapes. Complexity stems from the interplay among levels of biological organization as energy, and matter is integrated into larger units that superimpose onto the smaller parts. "What were wholes on one level become parts on a higher one." Small scale patterns do not necessarily explain large scale phenomena, otherwise captured in the expression (coined by Aristotle) 'the sum is greater than the parts'. "Complexity in ecology is of at least six distinct types: spatial, temporal, structural, process, behavioral, and geometric." From these principles, ecologists have identified emergent and self-organizing phenomena that operate at different environmental scales of influence, ranging from molecular to planetary, and these require different explanations at each integrative level. Ecological complexity relates to the dynamic resilience of ecosystems that transition to multiple shifting steady-states directed by random fluctuations of history. Long-term ecological studies provide important track records to better understand the complexity and resilience of ecosystems over longer temporal and broader spatial scales. These studies are managed by the International Long Term Ecological Network (LTER). The longest experiment in existence is the Park Grass Experiment, which was initiated in 1856. Another example is the Hubbard Brook study, which has been in operation since 1960. Holism Holism remains a critical part of the theoretical foundation in contemporary ecological studies. Holism addresses the biological organization of life that self-organizes into layers of emergent whole systems that function according to non-reducible properties. This means that higher-order patterns of a whole functional system, such as an ecosystem, cannot be predicted or understood by a simple summation of the parts. "New properties emerge because the components interact, not because the basic nature of the components is changed." Ecological studies are necessarily holistic as opposed to reductionistic. Holism has three scientific meanings or uses that identify with ecology: 1) the mechanistic complexity of ecosystems, 2) the practical description of patterns in quantitative reductionist terms where correlations may be identified but nothing is understood about the causal relations without reference to the whole system, which leads to 3) a metaphysical hierarchy whereby the causal relations of larger systems are understood without reference to the smaller parts. Scientific holism differs from mysticism that has appropriated the same term. An example of metaphysical holism is identified in the trend of increased exterior thickness in shells of different species. The reason for a thickness increase can be understood through reference to principles of natural selection via predation without the need to reference or understand the biomolecular properties of the exterior shells. Relation to evolution Ecology and evolutionary biology are considered sister disciplines of the life sciences. Natural selection, life history, development, adaptation, populations, and inheritance are examples of concepts that thread equally into ecological and evolutionary theory. Morphological, behavioural, and genetic traits, for example, can be mapped onto evolutionary trees to study the historical development of a species in relation to their functions and roles in different ecological circumstances. In this framework, the analytical tools of ecologists and evolutionists overlap as they organize, classify, and investigate life through common systematic principles, such as phylogenetics or the Linnaean system of taxonomy. The two disciplines often appear together, such as in the title of the journal Trends in Ecology and Evolution. There is no sharp boundary separating ecology from evolution, and they differ more in their areas of applied focus. Both disciplines discover and explain emergent and unique properties and processes operating across different spatial or temporal scales of organization. While the boundary between ecology and evolution is not always clear, ecologists study the abiotic and biotic factors that influence evolutionary processes, and evolution can be rapid, occurring on ecological timescales as short as one generation. Behavioural ecology All organisms can exhibit behaviours. Even plants express complex behaviour, including memory and communication. Behavioural ecology is the study of an organism's behaviour in its environment and its ecological and evolutionary implications. Ethology is the study of observable movement or behaviour in animals. This could include investigations of motile sperm of plants, mobile phytoplankton, zooplankton swimming toward the female egg, the cultivation of fungi by weevils, the mating dance of a salamander, or social gatherings of amoeba. Adaptation is the central unifying concept in behavioural ecology. Behaviours can be recorded as traits and inherited in much the same way that eye and hair colour can. Behaviours can evolve by means of natural selection as adaptive traits conferring functional utilities that increases reproductive fitness. Predator-prey interactions are an introductory concept into food-web studies as well as behavioural ecology. Prey species can exhibit different kinds of behavioural adaptations to predators, such as avoid, flee, or defend. Many prey species are faced with multiple predators that differ in the degree of danger posed. To be adapted to their environment and face predatory threats, organisms must balance their energy budgets as they invest in different aspects of their life history, such as growth, feeding, mating, socializing, or modifying their habitat. Hypotheses posited in behavioural ecology are generally based on adaptive principles of conservation, optimization, or efficiency. For example, "[t]he threat-sensitive predator avoidance hypothesis predicts that prey should assess the degree of threat posed by different predators and match their behaviour according to current levels of risk" or "[t]he optimal flight initiation distance occurs where expected postencounter fitness is maximized, which depends on the prey's initial fitness, benefits obtainable by not fleeing, energetic escape costs, and expected fitness loss due to predation risk." Elaborate sexual displays and posturing are encountered in the behavioural ecology of animals. The birds-of-paradise, for example, sing and display elaborate ornaments during courtship. These displays serve a dual purpose of signalling healthy or well-adapted individuals and desirable genes. The displays are driven by sexual selection as an advertisement of quality of traits among suitors. Cognitive ecology Cognitive ecology integrates theory and observations from evolutionary ecology and neurobiology, primarily cognitive science, in order to understand the effect that animal interaction with their habitat has on their cognitive systems and how those systems restrict behavior within an ecological and evolutionary framework. "Until recently, however, cognitive scientists have not paid sufficient attention to the fundamental fact that cognitive traits evolved under particular natural settings. With consideration of the selection pressure on cognition, cognitive ecology can contribute intellectual coherence to the multidisciplinary study of cognition." As a study involving the 'coupling' or interactions between organism and environment, cognitive ecology is closely related to enactivism, a field based upon the view that "...we must see the organism and environment as bound together in reciprocal specification and selection...". Social ecology Social-ecological behaviours are notable in the social insects, slime moulds, social spiders, human society, and naked mole-rats where eusocialism has evolved. Social behaviours include reciprocally beneficial behaviours among kin and nest mates and evolve from kin and group selection. Kin selection explains altruism through genetic relationships, whereby an altruistic behaviour leading to death is rewarded by the survival of genetic copies distributed among surviving relatives. The social insects, including ants, bees, and wasps are most famously studied for this type of relationship because the male drones are clones that share the same genetic make-up as every other male in the colony. In contrast, group selectionists find examples of altruism among non-genetic relatives and explain this through selection acting on the group; whereby, it becomes selectively advantageous for groups if their members express altruistic behaviours to one another. Groups with predominantly altruistic members survive better than groups with predominantly selfish members. Coevolution Ecological interactions can be classified broadly into a host and an associate relationship. A host is any entity that harbours another that is called the associate. Relationships between species that are mutually or reciprocally beneficial are called mutualisms. Examples of mutualism include fungus-growing ants employing agricultural symbiosis, bacteria living in the guts of insects and other organisms, the fig wasp and yucca moth pollination complex, lichens with fungi and photosynthetic algae, and corals with photosynthetic algae. If there is a physical connection between host and associate, the relationship is called symbiosis. Approximately 60% of all plants, for example, have a symbiotic relationship with arbuscular mycorrhizal fungi living in their roots forming an exchange network of carbohydrates for mineral nutrients. Indirect mutualisms occur where the organisms live apart. For example, trees living in the equatorial regions of the planet supply oxygen into the atmosphere that sustains species living in distant polar regions of the planet. This relationship is called commensalism because many others receive the benefits of clean air at no cost or harm to trees supplying the oxygen. If the associate benefits while the host suffers, the relationship is called parasitism. Although parasites impose a cost to their host (e.g., via damage to their reproductive organs or propagules, denying the services of a beneficial partner), their net effect on host fitness is not necessarily negative and, thus, becomes difficult to forecast. Co-evolution is also driven by competition among species or among members of the same species under the banner of reciprocal antagonism, such as grasses competing for growth space. The Red Queen Hypothesis, for example, posits that parasites track down and specialize on the locally common genetic defense systems of its host that drives the evolution of sexual reproduction to diversify the genetic constituency of populations responding to the antagonistic pressure. Biogeography Biogeography (an amalgamation of biology and geography) is the comparative study of the geographic distribution of organisms and the corresponding evolution of their traits in space and time. The Journal of Biogeography was established in 1974. Biogeography and ecology share many of their disciplinary roots. For example, the theory of island biogeography, published by the Robert MacArthur and Edward O. Wilson in 1967 is considered one of the fundamentals of ecological theory. Biogeography has a long history in the natural sciences concerning the spatial distribution of plants and animals. Ecology and evolution provide the explanatory context for biogeographical studies. Biogeographical patterns result from ecological processes that influence range distributions, such as migration and dispersal. and from historical processes that split populations or species into different areas. The biogeographic processes that result in the natural splitting of species explain much of the modern distribution of the Earth's biota. The splitting of lineages in a species is called vicariance biogeography and it is a sub-discipline of biogeography. There are also practical applications in the field of biogeography concerning ecological systems and processes. For example, the range and distribution of biodiversity and invasive species responding to climate change is a serious concern and active area of research in the context of global warming. r/K selection theory A population ecology concept is r/K selection theory, one of the first predictive models in ecology used to explain life-history evolution. The premise behind the r/K selection model is that natural selection pressures change according to population density. For example, when an island is first colonized, density of individuals is low. The initial increase in population size is not limited by competition, leaving an abundance of available resources for rapid population growth. These early phases of population growth experience density-independent forces of natural selection, which is called r-selection. As the population becomes more crowded, it approaches the island's carrying capacity, thus forcing individuals to compete more heavily for fewer available resources. Under crowded conditions, the population experiences density-dependent forces of natural selection, called K-selection. In the r/K-selection model, the first variable r is the intrinsic rate of natural increase in population size and the second variable K is the carrying capacity of a population. Different species evolve different life-history strategies spanning a continuum between these two selective forces. An r-selected species is one that has high birth rates, low levels of parental investment, and high rates of mortality before individuals reach maturity. Evolution favours high rates of fecundity in r-selected species. Many kinds of insects and invasive species exhibit r-selected characteristics. In contrast, a K-selected species has low rates of fecundity, high levels of parental investment in the young, and low rates of mortality as individuals mature. Humans and elephants are examples of species exhibiting K-selected characteristics, including longevity and efficiency in the conversion of more resources into fewer offspring. Molecular ecology The important relationship between ecology and genetic inheritance predates modern techniques for molecular analysis. Molecular ecological research became more feasible with the development of rapid and accessible genetic technologies, such as the polymerase chain reaction (PCR). The rise of molecular technologies and the influx of research questions into this new ecological field resulted in the publication Molecular Ecology in 1992. Molecular ecology uses various analytical techniques to study genes in an evolutionary and ecological context. In 1994, John Avise also played a leading role in this area of science with the publication of his book, Molecular Markers, Natural History and Evolution. Newer technologies opened a wave of genetic analysis into organisms once difficult to study from an ecological or evolutionary standpoint, such as bacteria, fungi, and nematodes. Molecular ecology engendered a new research paradigm for investigating ecological questions considered otherwise intractable. Molecular investigations revealed previously obscured details in the tiny intricacies of nature and improved resolution into probing questions about behavioural and biogeographical ecology. For example, molecular ecology revealed promiscuous sexual behaviour and multiple male partners in tree swallows previously thought to be socially monogamous. In a biogeographical context, the marriage between genetics, ecology, and evolution resulted in a new sub-discipline called phylogeography. Human ecology Ecology is as much a biological science as it is a human science. Human ecology is an interdisciplinary investigation into the ecology of our species. "Human ecology may be defined: (1) from a bioecological standpoint as the study of man as the ecological dominant in plant and animal communities and systems; (2) from a bioecological standpoint as simply another animal affecting and being affected by his physical environment; and (3) as a human being, somehow different from animal life in general, interacting with physical and modified environments in a distinctive and creative way. A truly interdisciplinary human ecology will most likely address itself to all three." The term was formally introduced in 1921, but many sociologists, geographers, psychologists, and other disciplines were interested in human relations to natural systems centuries prior, especially in the late 19th century. The ecological complexities human beings are facing through the technological transformation of the planetary biome has brought on the Anthropocene. The unique set of circumstances has generated the need for a new unifying science called coupled human and natural systems that builds upon, but moves beyond the field of human ecology. Ecosystems tie into human societies through the critical and all-encompassing life-supporting functions they sustain. In recognition of these functions and the incapability of traditional economic valuation methods to see the value in ecosystems, there has been a surge of interest in social-natural capital, which provides the means to put a value on the stock and use of information and materials stemming from ecosystem goods and services. Ecosystems produce, regulate, maintain, and supply services of critical necessity and beneficial to human health (cognitive and physiological), economies, and they even provide an information or reference function as a living library giving opportunities for science and cognitive development in children engaged in the complexity of the natural world. Ecosystems relate importantly to human ecology as they are the ultimate base foundation of global economics as every commodity, and the capacity for exchange ultimately stems from the ecosystems on Earth. Restoration Ecology Ecology is an employed science of restoration, repairing disturbed sites through human intervention, in natural resource management, and in environmental impact assessments. Edward O. Wilson predicted in 1992 that the 21st century "will be the era of restoration in ecology". Ecological science has boomed in the industrial investment of restoring ecosystems and their processes in abandoned sites after disturbance. Natural resource managers, in forestry, for example, employ ecologists to develop, adapt, and implement ecosystem based methods into the planning, operation, and restoration phases of land-use. Another example of conservation is seen on the east coast of the United States in Boston, MA. The city of Boston implemented the Wetland Ordinance, improving the stability of their wetland environments by implementing soil amendments that will improve groundwater storage and flow, and trimming or removal of vegetation that could cause harm to water quality. Ecological science is used in the methods of sustainable harvesting, disease, and fire outbreak management, in fisheries stock management, for integrating land-use with protected areas and communities, and conservation in complex geo-political landscapes. Relation to the environment The environment of ecosystems includes both physical parameters and biotic attributes. It is dynamically interlinked and contains resources for organisms at any time throughout their life cycle. Like ecology, the term environment has different conceptual meanings and overlaps with the concept of nature. Environment "includes the physical world, the social world of human relations and the built world of human creation." The physical environment is external to the level of biological organization under investigation, including abiotic factors such as temperature, radiation, light, chemistry, climate and geology. The biotic environment includes genes, cells, organisms, members of the same species (conspecifics) and other species that share a habitat. The distinction between external and internal environments, however, is an abstraction parsing life and environment into units or facts that are inseparable in reality. There is an interpenetration of cause and effect between the environment and life. The laws of thermodynamics, for example, apply to ecology by means of its physical state. With an understanding of metabolic and thermodynamic principles, a complete accounting of energy and material flow can be traced through an ecosystem. In this way, the environmental and ecological relations are studied through reference to conceptually manageable and isolated material parts. After the effective environmental components are understood through reference to their causes; however, they conceptually link back together as an integrated whole, or holocoenotic system as it was once called. This is known as the dialectical approach to ecology. The dialectical approach examines the parts but integrates the organism and the environment into a dynamic whole (or umwelt). Change in one ecological or environmental factor can concurrently affect the dynamic state of an entire ecosystem. Disturbance and resilience A disturbance is any process that changes or removes biomass from a community, such as a fire, flood, drought, or predation. Disturbances are both the cause and product of natural fluctuations within an ecological community. Biodiversity can protect ecosystems from disturbances. The effect of a disturbance is often hard to predict, but there are numerous examples in which a single species can massively disturb an ecosystem. For example, a single-celled protozoan has been able to kill up to 100% of sea urchins in some coral reefs in the Red Sea and Western Indian Ocean. Sea urchins enable complex reef ecosystems to thrive by eating algae that would otherwise inhibit coral growth. Similarly, invasive species can wreak havoc on ecosystems. For instance, invasive Burmese pythons have caused a 98% decline of small mammals in the Everglades. Metabolism and the early atmosphere The Earth was formed approximately 4.5 billion years ago. As it cooled and a crust and oceans formed, its atmosphere transformed from being dominated by hydrogen to one composed mostly of methane and ammonia. Over the next billion years, the metabolic activity of life transformed the atmosphere into a mixture of carbon dioxide, nitrogen, and water vapor. These gases changed the way that light from the sun hit the Earth's surface and greenhouse effects trapped heat. There were untapped sources of free energy within the mixture of reducing and oxidizing gasses that set the stage for primitive ecosystems to evolve and, in turn, the atmosphere also evolved. Throughout history, the Earth's atmosphere and biogeochemical cycles have been in a dynamic equilibrium with planetary ecosystems. The history is characterized by periods of significant transformation followed by millions of years of stability. The evolution of the earliest organisms, likely anaerobic methanogen microbes, started the process by converting atmospheric hydrogen into methane (4H2 + CO2 → CH4 + 2H2O). Anoxygenic photosynthesis reduced hydrogen concentrations and increased atmospheric methane, by converting hydrogen sulfide into water or other sulfur compounds (for example, 2H2S + CO2 + hv → CH2O + H2O + 2S). Early forms of fermentation also increased levels of atmospheric methane. The transition to an oxygen-dominant atmosphere (the Great Oxidation) did not begin until approximately 2.4–2.3 billion years ago, but photosynthetic processes started 0.3 to 1 billion years prior. Radiation: heat, temperature and light The biology of life operates within a certain range of temperatures. Heat is a form of energy that regulates temperature. Heat affects growth rates, activity, behaviour, and primary production. Temperature is largely dependent on the incidence of solar radiation. The latitudinal and longitudinal spatial variation of temperature greatly affects climates and consequently the distribution of biodiversity and levels of primary production in different ecosystems or biomes across the planet. Heat and temperature relate importantly to metabolic activity. Poikilotherms, for example, have a body temperature that is largely regulated and dependent on the temperature of the external environment. In contrast, homeotherms regulate their internal body temperature by expending metabolic energy. There is a relationship between light, primary production, and ecological energy budgets. Sunlight is the primary input of energy into the planet's ecosystems. Light is composed of electromagnetic energy of different wavelengths. Radiant energy from the sun generates heat, provides photons of light measured as active energy in the chemical reactions of life, and also acts as a catalyst for genetic mutation. Plants, algae, and some bacteria absorb light and assimilate the energy through photosynthesis. Organisms capable of assimilating energy by photosynthesis or through inorganic fixation of H2S are autotrophs. Autotrophs—responsible for primary production—assimilate light energy which becomes metabolically stored as potential energy in the form of biochemical enthalpic bonds. Physical environments Water Diffusion of carbon dioxide and oxygen is approximately 10,000 times slower in water than in air. When soils are flooded, they quickly lose oxygen, becoming hypoxic (an environment with O2 concentration below 2 mg/liter) and eventually completely anoxic where anaerobic bacteria thrive among the roots. Water also influences the intensity and spectral composition of light as it reflects off the water surface and submerged particles. Aquatic plants exhibit a wide variety of morphological and physiological adaptations that allow them to survive, compete, and diversify in these environments. For example, their roots and stems contain large air spaces (aerenchyma) that regulate the efficient transportation of gases (for example, CO2 and O2) used in respiration and photosynthesis. Salt water plants (halophytes) have additional specialized adaptations, such as the development of special organs for shedding salt and osmoregulating their internal salt (NaCl) concentrations, to live in estuarine, brackish, or oceanic environments. Anaerobic soil microorganisms in aquatic environments use nitrate, manganese ions, ferric ions, sulfate, carbon dioxide, and some organic compounds; other microorganisms are facultative anaerobes and use oxygen during respiration when the soil becomes drier. The activity of soil microorganisms and the chemistry of the water reduces the oxidation-reduction potentials of the water. Carbon dioxide, for example, is reduced to methane (CH4) by methanogenic bacteria. The physiology of fish is also specially adapted to compensate for environmental salt levels through osmoregulation. Their gills form electrochemical gradients that mediate salt excretion in salt water and uptake in fresh water. Gravity The shape and energy of the land are significantly affected by gravitational forces. On a large scale, the distribution of gravitational forces on the earth is uneven and influences the shape and movement of tectonic plates as well as influencing geomorphic processes such as orogeny and erosion. These forces govern many of the geophysical properties and distributions of ecological biomes across the Earth. On the organismal scale, gravitational forces provide directional cues for plant and fungal growth (gravitropism), orientation cues for animal migrations, and influence the biomechanics and size of animals. Ecological traits, such as allocation of biomass in trees during growth are subject to mechanical failure as gravitational forces influence the position and structure of branches and leaves. The cardiovascular systems of animals are functionally adapted to overcome the pressure and gravitational forces that change according to the features of organisms (e.g., height, size, shape), their behaviour (e.g., diving, running, flying), and the habitat occupied (e.g., water, hot deserts, cold tundra). Pressure Climatic and osmotic pressure places physiological constraints on organisms, especially those that fly and respire at high altitudes, or dive to deep ocean depths. These constraints influence vertical limits of ecosystems in the biosphere, as organisms are physiologically sensitive and adapted to atmospheric and osmotic water pressure differences. For example, oxygen levels decrease with decreasing pressure and are a limiting factor for life at higher altitudes. Water transportation by plants is another important ecophysiological process affected by osmotic pressure gradients. Water pressure in the depths of oceans requires that organisms adapt to these conditions. For example, diving animals such as whales, dolphins, and seals are specially adapted to deal with changes in sound due to water pressure differences. Differences between hagfish species provide another example of adaptation to deep-sea pressure through specialized protein adaptations. Wind and turbulence Turbulent forces in air and water affect the environment and ecosystem distribution, form, and dynamics. On a planetary scale, ecosystems are affected by circulation patterns in the global trade winds. Wind power and the turbulent forces it creates can influence heat, nutrient, and biochemical profiles of ecosystems. For example, wind running over the surface of a lake creates turbulence, mixing the water column and influencing the environmental profile to create thermally layered zones, affecting how fish, algae, and other parts of the aquatic ecosystem are structured. Wind speed and turbulence also influence evapotranspiration rates and energy budgets in plants and animals. Wind speed, temperature and moisture content can vary as winds travel across different land features and elevations. For example, the westerlies come into contact with the coastal and interior mountains of western North America to produce a rain shadow on the leeward side of the mountain. The air expands and moisture condenses as the winds increase in elevation; this is called orographic lift and can cause precipitation. This environmental process produces spatial divisions in biodiversity, as species adapted to wetter conditions are range-restricted to the coastal mountain valleys and unable to migrate across the xeric ecosystems (e.g., of the Columbia Basin in western North America) to intermix with sister lineages that are segregated to the interior mountain systems. Fire Plants convert carbon dioxide into biomass and emit oxygen into the atmosphere. By approximately 350 million years ago (the end of the Devonian period), photosynthesis had brought the concentration of atmospheric oxygen above 17%, which allowed combustion to occur. Fire releases CO2 and converts fuel into ash and tar. Fire is a significant ecological parameter that raises many issues pertaining to its control and suppression. While the issue of fire in relation to ecology and plants has been recognized for a long time, Charles Cooper brought attention to the issue of forest fires in relation to the ecology of forest fire suppression and management in the 1960s. Native North Americans were among the first to influence fire regimes by controlling their spread near their homes or by lighting fires to stimulate the production of herbaceous foods and basketry materials. Fire creates a heterogeneous ecosystem age and canopy structure, and the altered soil nutrient supply and cleared canopy structure opens new ecological niches for seedling establishment. Most ecosystems are adapted to natural fire cycles. Plants, for example, are equipped with a variety of adaptations to deal with forest fires. Some species (e.g., Pinus halepensis) cannot germinate until after their seeds have lived through a fire or been exposed to certain compounds from smoke. Environmentally triggered germination of seeds is called serotiny. Fire plays a major role in the persistence and resilience of ecosystems. Soils Soil is the living top layer of mineral and organic dirt that covers the surface of the planet. It is the chief organizing centre of most ecosystem functions, and it is of critical importance in agricultural science and ecology. The decomposition of dead organic matter (for example, leaves on the forest floor), results in soils containing minerals and nutrients that feed into plant production. The whole of the planet's soil ecosystems is called the pedosphere where a large biomass of the Earth's biodiversity organizes into trophic levels. Invertebrates that feed and shred larger leaves, for example, create smaller bits for smaller organisms in the feeding chain. Collectively, these organisms are the detritivores that regulate soil formation. Tree roots, fungi, bacteria, worms, ants, beetles, centipedes, spiders, mammals, birds, reptiles, amphibians, and other less familiar creatures all work to create the trophic web of life in soil ecosystems. Soils form composite phenotypes where inorganic matter is enveloped into the physiology of a whole community. As organisms feed and migrate through soils they physically displace materials, an ecological process called bioturbation. This aerates soils and stimulates heterotrophic growth and production. Soil microorganisms are influenced by and are fed back into the trophic dynamics of the ecosystem. No single axis of causality can be discerned to segregate the biological from geomorphological systems in soils. Paleoecological studies of soils places the origin for bioturbation to a time before the Cambrian period. Other events, such as the evolution of trees and the colonization of land in the Devonian period played a significant role in the early development of ecological trophism in soils. Biogeochemistry and climate Ecologists study and measure nutrient budgets to understand how these materials are regulated, flow, and recycled through the environment. This research has led to an understanding that there is global feedback between ecosystems and the physical parameters of this planet, including minerals, soil, pH, ions, water, and atmospheric gases. Six major elements (hydrogen, carbon, nitrogen, oxygen, sulfur, and phosphorus; H, C, N, O, S, and P) form the constitution of all biological macromolecules and feed into the Earth's geochemical processes. From the smallest scale of biology, the combined effect of billions upon billions of ecological processes amplify and ultimately regulate the biogeochemical cycles of the Earth. Understanding the relations and cycles mediated between these elements and their ecological pathways has significant bearing toward understanding global biogeochemistry. The ecology of global carbon budgets gives one example of the linkage between biodiversity and biogeochemistry. It is estimated that the Earth's oceans hold 40,000 gigatonnes (Gt) of carbon, that vegetation and soil hold 2070 Gt, and that fossil fuel emissions are 6.3 Gt carbon per year. There have been major restructurings in these global carbon budgets during the Earth's history, regulated to a large extent by the ecology of the land. For example, through the early-mid Eocene volcanic outgassing, the oxidation of methane stored in wetlands, and seafloor gases increased atmospheric CO2 (carbon dioxide) concentrations to levels as high as 3500 ppm. In the Oligocene, from twenty-five to thirty-two million years ago, there was another significant restructuring of the global carbon cycle as grasses evolved a new mechanism of photosynthesis, C4 photosynthesis, and expanded their ranges. This new pathway evolved in response to the drop in atmospheric CO2 concentrations below 550 ppm. The relative abundance and distribution of biodiversity alters the dynamics between organisms and their environment such that ecosystems can be both cause and effect in relation to climate change. Human-driven modifications to the planet's ecosystems (e.g., disturbance, biodiversity loss, agriculture) contributes to rising atmospheric greenhouse gas levels. Transformation of the global carbon cycle in the next century is projected to raise planetary temperatures, lead to more extreme fluctuations in weather, alter species distributions, and increase extinction rates. The effect of global warming is already being registered in melting glaciers, melting mountain ice caps, and rising sea levels. Consequently, species distributions are changing along waterfronts and in continental areas where migration patterns and breeding grounds are tracking the prevailing shifts in climate. Large sections of permafrost are also melting to create a new mosaic of flooded areas having increased rates of soil decomposition activity that raises methane (CH4) emissions. There is concern over increases in atmospheric methane in the context of the global carbon cycle, because methane is a greenhouse gas that is 23 times more effective at absorbing long-wave radiation than CO2 on a 100-year time scale. Hence, there is a relationship between global warming, decomposition and respiration in soils and wetlands producing significant climate feedbacks and globally altered biogeochemical cycles. History Early beginnings Ecology has a complex origin, due in large part to its interdisciplinary nature. Ancient Greek philosophers such as Hippocrates and Aristotle were among the first to record observations on natural history. However, they viewed life in terms of essentialism, where species were conceptualized as static unchanging things while varieties were seen as aberrations of an idealized type. This contrasts against the modern understanding of ecological theory where varieties are viewed as the real phenomena of interest and having a role in the origins of adaptations by means of natural selection. Early conceptions of ecology, such as a balance and regulation in nature can be traced to Herodotus (died c. 425 BC), who described one of the earliest accounts of mutualism in his observation of "natural dentistry". Basking Nile crocodiles, he noted, would open their mouths to give sandpipers safe access to pluck leeches out, giving nutrition to the sandpiper and oral hygiene for the crocodile. Aristotle was an early influence on the philosophical development of ecology. He and his student Theophrastus made extensive observations on plant and animal migrations, biogeography, physiology, and their behavior, giving an early analogue to the modern concept of an ecological niche. Ernst Haeckel (left) and Eugenius Warming (right), two founders of ecology Ecological concepts such as food chains, population regulation, and productivity were first developed in the 1700s, through the published works of microscopist Antonie van Leeuwenhoek (1632–1723) and botanist Richard Bradley (1688?–1732). Biogeographer Alexander von Humboldt (1769–1859) was an early pioneer in ecological thinking and was among the first to recognize ecological gradients, where species are replaced or altered in form along environmental gradients, such as a cline forming along a rise in elevation. Humboldt drew inspiration from Isaac Newton, as he developed a form of "terrestrial physics". In Newtonian fashion, he brought a scientific exactitude for measurement into natural history and even alluded to concepts that are the foundation of a modern ecological law on species-to-area relationships. Natural historians, such as Humboldt, James Hutton, and Jean-Baptiste Lamarck (among others) laid the foundations of the modern ecological sciences. The term "ecology" was coined by Ernst Haeckel in his book Generelle Morphologie der Organismen (1866). Haeckel was a zoologist, artist, writer, and later in life a professor of comparative anatomy. Opinions differ on who was the founder of modern ecological theory. Some mark Haeckel's definition as the beginning; others say it was Eugenius Warming with the writing of Oecology of Plants: An Introduction to the Study of Plant Communities (1895), or Carl Linnaeus' principles on the economy of nature that matured in the early 18th century. Linnaeus founded an early branch of ecology that he called the economy of nature. His works influenced Charles Darwin, who adopted Linnaeus' phrase on the economy or polity of nature in The Origin of Species. Linnaeus was the first to frame the balance of nature as a testable hypothesis. Haeckel, who admired Darwin's work, defined ecology in reference to the economy of nature, which has led some to question whether ecology and the economy of nature are synonymous. From Aristotle until Darwin, the natural world was predominantly considered static and unchanging. Prior to The Origin of Species, there was little appreciation or understanding of the dynamic and reciprocal relations between organisms, their adaptations, and the environment. An exception is the 1789 publication Natural History of Selborne by Gilbert White (1720–1793), considered by some to be one of the earliest texts on ecology. While Charles Darwin is mainly noted for his treatise on evolution, he was one of the founders of soil ecology, and he made note of the first ecological experiment in The Origin of Species. Evolutionary theory changed the way that researchers approached the ecological sciences. Since 1900 Modern ecology is a young science that first attracted substantial scientific attention toward the end of the 19th century (around the same time that evolutionary studies were gaining scientific interest). The scientist Ellen Swallow Richards adopted the term "oekology" (which eventually morphed into home economics) in the U.S. as early as 1892. In the early 20th century, ecology transitioned from a more descriptive form of natural history to a more analytical form of scientific natural history. Frederic Clements published the first American ecology book in 1905, presenting the idea of plant communities as a superorganism. This publication launched a debate between ecological holism and individualism that lasted until the 1970s. Clements' superorganism concept proposed that ecosystems progress through regular and determined stages of seral development that are analogous to the developmental stages of an organism. The Clementsian paradigm was challenged by Henry Gleason, who stated that ecological communities develop from the unique and coincidental association of individual organisms. This perceptual shift placed the focus back onto the life histories of individual organisms and how this relates to the development of community associations. The Clementsian superorganism theory was an overextended application of an idealistic form of holism. The term "holism" was coined in 1926 by Jan Christiaan Smuts, a South African general and polarizing historical figure who was inspired by Clements' superorganism concept. Around the same time, Charles Elton pioneered the concept of food chains in his classical book Animal Ecology. Elton defined ecological relations using concepts of food chains, food cycles, and food size, and described numerical relations among different functional groups and their relative abundance. Elton's 'food cycle' was replaced by 'food web' in a subsequent ecological text. Alfred J. Lotka brought in many theoretical concepts applying thermodynamic principles to ecology. In 1942, Raymond Lindeman wrote a landmark paper on the trophic dynamics of ecology, which was published posthumously after initially being rejected for its theoretical emphasis. Trophic dynamics became the foundation for much of the work to follow on energy and material flow through ecosystems. Robert MacArthur advanced mathematical theory, predictions, and tests in ecology in the 1950s, which inspired a resurgent school of theoretical mathematical ecologists. Ecology also has developed through contributions from other nations, including Russia's Vladimir Vernadsky and his founding of the biosphere concept in the 1920s and Japan's Kinji Imanishi and his concepts of harmony in nature and habitat segregation in the 1950s. Scientific recognition of contributions to ecology from non-English-speaking cultures is hampered by language and translation barriers. Ecology surged in popular and scientific interest during the 1960–1970s environmental movement. There are strong historical and scientific ties between ecology, environmental management, and protection. The historical emphasis and poetic naturalistic writings advocating the protection of wild places by notable ecologists in the history of conservation biology, such as Aldo Leopold and Arthur Tansley, have been seen as far removed from urban centres where, it is claimed, the concentration of pollution and environmental degradation is located. Palamar (2008) notes an overshadowing by mainstream environmentalism of pioneering women in the early 1900s who fought for urban health ecology (then called euthenics) and brought about changes in environmental legislation. Women such as Ellen Swallow Richards and Julia Lathrop, among others, were precursors to the more popularized environmental movements after the 1950s. In 1962, marine biologist and ecologist Rachel Carson's book Silent Spring helped to mobilize the environmental movement by alerting the public to toxic pesticides, such as DDT, bioaccumulating in the environment. Carson used ecological science to link the release of environmental toxins to human and ecosystem health. Since then, ecologists have worked to bridge their understanding of the degradation of the planet's ecosystems with environmental politics, law, restoration, and natural resources management.

Degrowth

Degrowth is an academic and social movement critical of the concept of growth in gross domestic product as a measure of human and economic development. The idea of degrowth is based on ideas and research from economic anthropology, ecological economics, environmental sciences, and development studies. It argues that modern capitalism's unitary focus on growth causes widespread ecological damage and is unnecessary for the further increase of human living standards. Degrowth theory has been met with both academic acclaim and considerable criticism. Degrowth's main argument is that an infinite expansion of the economy is fundamentally contradictory to the finiteness of material resources on Earth. It argues that economic growth measured by GDP should be abandoned as a policy objective. Policy should instead focus on economic and social metrics such as life expectancy, health, education, housing, and ecologically sustainable work as indicators of both ecosystems and human well-being. Degrowth theorists posit that this would increase human living standards and ecological preservation even as GDP growth slows. Degrowth theory is highly critical of free market capitalism, and it highlights the importance of extensive public services, care work, self-organization, commons, relational goods, community, and work sharing. Degrowth theory partly orients itself as a critique of green capitalism or as a radical alternative to the market-based, sustainable development goal (SDG) model of addressing ecological overshoot and environmental collapse. A 2024 review of degrowth studies over the past 10 years showed that most were of poor quality: almost 90% were opinions rather than analysis, few used quantitative or qualitative data, and even fewer ones used formal modelling; the latter used small samples or a focus on non-representative cases. Also most studies offered subjective policy advice, but lacked policy evaluation and integration with insights from the literature on environmental/climate policies. Background The "degrowth" movement arose from concerns over the consequences of the productivism and consumerism associated with industrial societies (whether capitalist or socialist) including: The reduced availability of energy sources (see peak oil); The destabilization of Earth's ecosystems upon which all life on Earth depends (see Holocene Extinction, Anthropocene, global warming, pollution, current biodiversity loss); The rise of negative societal side-effects (unsustainable development, poorer health, poverty); and The ever-expanding use of resources by Global North countries to satisfy lifestyles that consume more food and energy, and produce greater waste, at the expense of the Global South (see neocolonialism). A 2017 review of the research literature on degrowth, found that it focused on three main goals: (1) reduction of environmental degradation; (2) redistribution of income and wealth locally and globally; (3) promotion of a social transition from economic materialism to participatory culture. Decoupling The concept of decoupling denotes decoupling economic growth, usually measured in GDP growth, GDP per capita growth or GNI per capita growth from the use of natural resources and greenhouse gas (GHG) emissions. Absolute decoupling refers to GDP growth coinciding with a reduction in natural resource use and GHG emissions, while relative decoupling describes an increase in resource use and GHG emissions lower than the increase in GDP growth. The degrowth movement heavily critiques this idea and argues that absolute decoupling is only possible for short periods, specific locations, or with small mitigation rates. In 2021 NGO European Environmental Bureau called stated that "not only is there no empirical evidence supporting the existence of a decoupling of economic growth from environmental pressures on anywhere near the scale needed to deal with environmental breakdown", and that reported cases of existing eco-economic decouplings either depict relative decoupling and/or are observed only temporarily and/or only on a local scale, arguing that alternatives to eco-economic decoupling are needed. This is supported by several other studies which state that absolute decoupling is highly unlikely to be achieved fast enough to prevent global warming over 1.5 °C or 2 °C, even under optimistic policy conditions. Major criticism of this view points out that Degrowth is politically unpalatable, defaulting towards the more free market green growth orthodoxy as a set of solutions that is more politically tenable. The problems with the SDG process are political rather than technical, Ezra Klein of the New York Times claims in summary of these criticisms, and degrowth has less plausibility than green growth as a democratic political platform. However, in a recent review of efforts toward Sustain Development Goals by the Council of Foreign Relations in 2023 it was found that progress toward 50% of the minimum viable SDG's have stalled and 30% of these verticals have reversed (or are getting worse, rather than better). Thus, while it may be true that Degrowth will be 'a difficult sell' (per Ezra Klein) to introduce via democratic voluntarism, the critique of SDG's and decoupling against green capitalism leveled by Degrowth theorists appear to have predictive power. Resource depletion Degrowth proponents argue that economic expansion must be met with a corresponding increase in resource consumption. Non-renewable resources, like petroleum, have a limited supply and can eventually be exhausted. Similarly, renewable resources can also be depleted if they are harvested at unsustainable rates for prolonged periods. An example of this depletion is evident in the case of caviar production in the Caspian Sea. Supporters of degrowth contend that reducing demand is the sole permanent solution to bridging the demand gap. To sustain renewable resources, both demand and production must be regulated to levels that avert depletion and ensure environmental sustainability. Transitioning to a society less reliant on oil is crucial for averting societal collapse as non-renewable resources dwindle. Degrowth can also be interpreted as a plea for resource reallocation, aiming to halt unsustainable practices of transforming certain entities into resources, such as non-renewable natural resources. Instead, the focus shifts towards identifying and utilizing alternative resources, such as renewable human capabilities. Ecological footprint The ecological footprint measures human demand on the Earth's ecosystems by comparing human demand with the Earth's ecological capacity to regenerate. It represents the amount of biologically productive land and sea area required to regenerate the resources a human population consumes and to absorb and render harmless the corresponding waste. According to a 2005 Global Footprint Network report, inhabitants of high-income countries live off of 6.4 global hectares (gHa), while those from low-income countries live off of a single gHa. For example, while each inhabitant of Bangladesh lives off of what they produce from 0.56 gHa, a North American requires 12.5 gHa. Each inhabitant of North America uses 22.3 times as much land as a Bangladeshi. According to the same report, the average number of global hectares per person was 2.1, while current consumption levels have reached 2.7 hectares per person. For the world's population to attain the living standards typical of European countries, the resources of between three and eight planet Earths would be required with current levels of efficiency and means of production. For world economic equality to be achieved with the currently available resources, proponents say rich countries would have to reduce their standard of living through degrowth. The constraints on resources would eventually lead to a forced reduction in consumption. A controlled reduction of consumption would reduce the trauma of this change, assuming no technological changes increase the planet's carrying capacity. Multiple studies now demonstrate that in many affluent countries per-capita energy consumption could be decreased substantially and quality living standards still be maintained. Sustainable development Degrowth ideology opposes all manifestations of productivism, which advocates that economic productivity and growth should be the primary objectives of human organization. Consequently, it stands in opposition to the prevailing model of sustainable development. While the concept of sustainability aligns with some aspects of degrowth philosophy, sustainable development, as conventionally understood, is based on mainstream development principles focused on augmenting economic growth and consumption. Degrowth views sustainable development as contradictory because any development reliant on growth within a finite and ecologically strained context is deemed intrinsically unsustainable. Development based on growth in a finite, environmentally stressed world is viewed as inherently unsustainable. Critics of degrowth argue that a slowing of economic growth would result in increased unemployment, increased poverty, and decreased income per capita. Many who believe in negative environmental consequences of growth still advocate for economic growth in the South, even if not in the North. Slowing economic growth would fail to deliver the benefits of degrowth — self-sufficiency and material responsibility — and would indeed lead to decreased employment. Rather, degrowth proponents advocate the complete abandonment of the current (growth) economic model, suggesting that relocalizing and abandoning the global economy in the Global South would allow people of the South to become more self-sufficient and would end the overconsumption and exploitation of Southern resources by the North. Supporters of degrowth view it as a potential method to shield ecosystems from human exploitation. Within this concept, there is an emphasis on communal stewardship of the environment, fostering a symbiotic relationship between humans and nature. Degrowth recognizes ecosystems as valuable entities beyond their utility as mere sources of resources. During the Second International Conference on degrowth, discussions encompassed concepts like implementing a maximum wage and promoting open borders. Degrowth advocates an ethical shift that challenges the notion that high-resource consumption lifestyles are desirable. Additionally, alternative perspectives on degrowth include addressing perceived historical injustices perpetrated by the global North through centuries of colonization and exploitation, advocating for wealth redistribution. Determining the appropriate scale of action remains a focal point of debate within degrowth movements. Some researchers believe that the world is poised to experience a Great Transformation, either by disastrous events or intentional design. They maintain that ecological economics must incorporate Postdevelopment theories, Buen vivir, and degrowth to affect the change necessary to avoid these potentially catastrophic events. A 2022 paper by Mark Diesendorf found that limiting global warming to 1,5 degrees with no overshoot would require a reduction of energy consumption. It describes (chapters 4–5) degrowth toward a steady state economy as possible and probably positive. The study ends with the words: "The case for a transition to a steady-state economy with low throughput and low emissions, initially in the high-income economies and then in rapidly growing economies, needs more serious attention and international cooperation. "Rebound effect" Technologies designed to reduce resource use and improve efficiency are often touted as sustainable or green solutions. Degrowth literature, however, warns about these technological advances due to the "rebound effect", also known as Jevons paradox. This concept is based on observations that when a less resource-exhaustive technology is introduced, behavior surrounding the use of that technology may change, and consumption of that technology could increase or even offset any potential resource savings. In light of the rebound effect, proponents of degrowth hold that the only effective "sustainable" solutions must involve a complete rejection of the growth paradigm and a move to a degrowth paradigm. There are also fundamental limits to technological solutions in the pursuit of degrowth, as all engagements with technology increase the cumulative matter-energy throughput. However, the convergence of digital commons of knowledge and design with distributed manufacturing technologies may arguably hold potential for building degrowth future scenarios. Mitigation of climate change and determinants of 'growth' Scientists report that degrowth scenarios, where economic output either "declines" or declines in terms of contemporary economic metrics such as current GDP, have been neglected in considerations of 1.5 °C scenarios reported by the Intergovernmental Panel on Climate Change (IPCC), finding that investigated degrowth scenarios "minimize many key risks for feasibility and sustainability compared to technology-driven pathways" with a core problem of such being feasibility in the context of contemporary decision-making of politics and globalized rebound- and relocation-effects. However, structurally realigning 'economic growth' and socioeconomic activity determination-structures may not be widely debated in both the degrowth community and in degrowth research which may largely focus on reducing economic growth either more generally or without structural alternative but with e.g. nonsystemic political interventions. Similarly, many green growth advocates suggest that contemporary socioeconomic mechanisms and metrics – including for economic growth – can be continued with forms of nonstructural "energy-GDP decoupling". A study concluded that public services are associated with higher human need satisfaction and lower energy requirements while contemporary forms of economic growth are linked with the opposite, with the contemporary economic system being fundamentally misaligned with the twin goals of meeting human needs and ensuring ecological sustainability, suggesting that prioritizing human well-being and ecological sustainability would be preferable to overgrowth in current metrics of economic growth. The word 'degrowth' was mentioned 28 times in the United Nations IPCC Sixth Assessment Report by Working Group III published in April 2022. Open Localism Open localism is a concept that has been promoted by the degrowth community when envisioning an alternative set of social relations and economic organization. It builds upon the political philosophies of localism and is based on values such as diversity, ecologies of knowledge, and openness. Open localism does not look to create an enclosed community but rather to circulate production locally in an open and integrative manner. Open localism is a direct challenge to the acts of closure regarding identitarian politics. By producing and consuming as much as possible locally, community members enhance their relationships with one another and the surrounding environment. Degrowth's ideas around open localism share similarities with ideas around the commons while also having clear differences. On the one hand, open localism promotes localized, common production in cooperative-like styles similar to some versions of how commons are organized. On the other hand, open localism does not impose any set of rules or regulations creating a defined boundary, rather it favours a cosmopolitan approach. Feminism The degrowth movement builds on feminist economics that has criticized measures of economic growth like the GDP as it excludes work mainly done by women such as unpaid care work (the work performed to fulfill people's needs) and reproductive work (the work sustaining life), first argued by Marilyn Waring. Further, degrowth draws on the critique of socialist feminists like Silvia Federici and Nancy Fraser claiming that capitalist growth builds on the exploitation of women's work. Instead of devaluing it, degrowth centers the economy around care, proposing that care work should be organized as a commons. Centering care goes hand in hand with changing society's time regimes. Degrowth scholars propose a working time reduction. As this does not necessarily lead to gender justice, the redistribution of care work has to be equally pushed. A concrete proposal by Frigga Haug is the 4-in-1 perspective that proposes 4 hours of wage work per day, freeing time for 4 hours of care work, 4 hours of political activities in a direct democracy, and 4 hours of personal development through learning. Furthermore, degrowth draws on materialist ecofeminisms that state the parallel of the exploitation of women and nature in growth-based societies and proposes a subsistence perspective conceptualized by Maria Mies and Ariel Salleh. Synergies and opportunities for cross-fertilization between degrowth and feminism were proposed in 2022, through networks including the Feminisms and Degrowth Alliance (FaDA). FaDA argued that the 2023 launch of Degrowth Journal created "a convivial space for generating and exploring knowledge and practice from diverse perspectives". Decolonialism A relevant concept within the theory of degrowth is decolonialism, which refers to putting an end to the perpetuation of political, social, economic, religious, racial, gender, and epistemological relations of power, domination, and hierarchy of the global north over the global south. The foundation of this relationship lies in the claim that the imminent socio-ecological collapse is caused by capitalism, which is sustained by economic growth. This economic growth in turn can only be maintained under the eaves of colonialism and extractivism, perpetuating asymmetric power relationships between territories. Colonialism is understood as the appropriation of common goods, resources, and labor, which is antagonistic to degrowth principles. Through colonial domination, capital depresses the prices of inputs and colonial cheapening occurs to the detriment of the oppressed countries. Degrowth criticizes these appropriation mechanisms and enclosure of one territory over another and proposes a provision of human needs through disaccumulation, de-enclosure, and decommodification. It also reconciles with social movements and seeks to recognize the ecological debt to achieve the catch-up, which is postulated as impossible without decolonization. In practice, decolonial practices close to degrowth are observed, such as the movement of Buen vivir or sumak kawsay by various indigenous peoples. Policies There is a wide range of policy proposals associated with degrowth. In 2022, Nick Fitzpatrick, Timothée Parrique and Inês Cosme conducted a comprehensive survey of degrowth literature from 2005 to 2020 and found 530 specific policy proposals with "50 goals, 100 objectives, 380 instruments". The survey found that the ten most frequently cited proposals were: universal basic incomes, work-time reductions, job guarantees with a living wage, maximum income caps, declining caps on resource use and emissions, not-for-profit cooperatives, holding deliberative forums, reclaiming the commons, establishing ecovillages, and housing cooperatives. To address the common criticism that such policies are not realistically financeable, economic anthropologist Jason Hickel sees an opportunity to learn from modern monetary theory, which argues that monetary sovereign states can issue the money needed to pay for anything available in the national economy without the need to first tax their citizens for the requisite funds. Taxation, credit regulations and price controls could be used to mitigate the inflation this may generate, while also reducing consumption. Origins of the movement The contemporary degrowth movement can trace its roots back to the anti-industrialist trends of the 19th century, developed in Great Britain by John Ruskin, William Morris and the Arts and Crafts movement (1819–1900), in the United States by Henry David Thoreau (1817–1862), and in Russia by Leo Tolstoy (1828–1910). Degrowth movements draw on the values of humanism, enlightenment, anthropology and human rights. Club of Rome reports In 1968, the Club of Rome, a think tank headquartered in Winterthur, Switzerland, asked researchers at the Massachusetts Institute of Technology for a report on the limits of our world system and the constraints it puts on human numbers and activity. The report, called The Limits to Growth, published in 1972, became the first significant study to model the consequences of economic growth. The reports (also known as the Meadows Reports) are not strictly the founding texts of the degrowth movement, as these reports only advise zero growth, and have also been used to support the sustainable development movement. Still, they are considered the first studies explicitly presenting economic growth as a key reason for the increase in global environmental problems such as pollution, shortage of raw materials, and the destruction of ecosystems. The Limits to Growth: The 30-Year Update was published in 2004, and in 2012, a 40-year forecast from Jørgen Randers, one of the book's original authors, was published as 2052: A Global Forecast for the Next Forty Years. In 2021, Club of Rome committee member Gaya Herrington published an article comparing the proposed models' predictions against empirical data trends. The BAU2 ("Business as Usual 2") scenario, predicting "collapse through pollution", as well as the CT ("Comprehensive Technology") scenario, predicting exceptional technological development and gradual decline, were found to align most closely with data observed as of 2019. In September 2022, the Club of Rome released updated predictive models and policy recommendations in a general-audiences book titled Earth for all – A survival guide to humanity. Lasting influence of Georgescu-Roegen The degrowth movement recognises Romanian American mathematician, statistician and economist Nicholas Georgescu-Roegen as the main intellectual figure inspiring the movement. In his 1971 work, The Entropy Law and the Economic Process, Georgescu-Roegen argues that economic scarcity is rooted in physical reality; that all natural resources are irreversibly degraded when put to use in economic activity; that the carrying capacity of Earth—that is, Earth's capacity to sustain human populations and consumption levels—is bound to decrease sometime in the future as Earth's finite stock of mineral resources is presently being extracted and put to use; and consequently, that the world economy as a whole is heading towards an inevitable future collapse. Georgescu-Roegen's intellectual inspiration to degrowth dates back to the 1970s. When Georgescu-Roegen delivered a lecture at the University of Geneva in 1974, he made a lasting impression on the young, newly graduated French historian and philosopher, Jacques Grinevald, who had earlier been introduced to Georgescu-Roegen's works by an academic advisor. Georgescu-Roegen and Grinevald became friends, and Grinevald devoted his research to a closer study of Georgescu-Roegen's work. As a result, in 1979, Grinevald published a French translation of a selection of Georgescu-Roegen's articles entitled Demain la décroissance: Entropie – Écologie – Économie ('Tomorrow, the Decline: Entropy – Ecology – Economy'). Georgescu-Roegen, who spoke French fluently, approved the use of the term décroissance in the title of the French translation. The book gained influence in French intellectual and academic circles from the outset. Later, the book was expanded and republished in 1995 and once again in 2006; however, the word Demain ('tomorrow') was removed from the book's title in the second and third editions. By the time Grinevald suggested the term décroissance to form part of the title of the French translation of Georgescu-Roegen's work, the term had already permeated French intellectual circles since the early 1970s to signify a deliberate political action to downscale the economy on a permanent and voluntary basis. Simultaneously, but independently, Georgescu-Roegen criticised the ideas of The Limits to Growth and Herman Daly's steady-state economy in his article, "Energy and Economic Myths", delivered as a series of lectures from 1972, but not published before 1975. In the article, Georgescu-Roegen stated the following: When reading this particular passage of the text, Grinevald realised that no professional economist of any orientation had ever reasoned like this before. Grinevald also realised the congruence of Georgescu-Roegen's viewpoint and the French debates occurring at the time; this resemblance was captured in the title of the French edition. The translation of Georgescu-Roegen's work into French both fed on and gave further impetus to the concept of décroissance in France—and everywhere else in the francophone world—thereby creating something of an intellectual feedback loop. By the 2000s, when décroissance was to be translated from French back into English as the catchy banner for the new social movement, the original term "decline" was deemed inappropriate and misdirected for the purpose: "Decline" usually refers to an unexpected, unwelcome, and temporary economic recession, something to be avoided or quickly overcome. Instead, the neologism "degrowth" was coined to signify a deliberate political action to downscale the economy on a permanent, conscious basis—as in the prevailing French usage of the term—something good to be welcomed and maintained, or so followers believe. When the first international degrowth conference was held in Paris in 2008, the participants honoured Georgescu-Roegen and his work. In his manifesto on Petit traité de la décroissance sereine ("Farewell to Growth"), the leading French champion of the degrowth movement, Serge Latouche, credited Georgescu-Roegen as the "main theoretical source of degrowth". Likewise, Italian degrowth theorist Mauro Bonaiuti considered Georgescu-Roegen's work to be "one of the analytical cornerstones of the degrowth perspective". Schumacher and Buddhist economics E. F. Schumacher's 1973 book Small Is Beautiful predates a unified degrowth movement but nonetheless serves as an important basis for degrowth ideas. In this book he critiques the neo-liberal model of economic development, arguing that an increasing "standard of living", based on consumption is absurd as a goal of economic activity and development. Instead, under what he refers to as Buddhist economics, we should aim to maximize well-being while minimizing consumption. Ecological and social issues In January 1972, Edward Goldsmith and Robert Prescott-Allen—editors of The Ecologist—published A Blueprint for Survival, which called for a radical programme of decentralisation and deindustrialization to prevent what the authors referred to as "the breakdown of society and the irreversible disruption of the life-support systems on this planet". In 2019, a summary for policymakers of the largest, most comprehensive study to date of biodiversity and ecosystem services was published by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services. The report was finalised in Paris. The main conclusions: Over the last 50 years, the state of nature has deteriorated at an unprecedented and accelerating rate. The main drivers of this deterioration have been changes in land and sea use, exploitation of living beings, climate change, pollution and invasive species. These five drivers, in turn, are caused by societal behaviors, from consumption to governance. Damage to ecosystems undermines 35 of 44 selected UN targets, including the UN General Assembly's Sustainable Development Goals for poverty, hunger, health, water, cities' climate, oceans and land. It can cause problems with food, water and humanity's air supply. To fix the problem, humanity needs transformative change, including sustainable agriculture, reductions in consumption and waste, fishing quotas and collaborative water management. Page 8 of the report proposes "enabling visions of a good quality of life that do not entail ever-increasing material consumption" as one of the main measures. The report states that "Some pathways chosen to achieve the goals related to energy, economic growth, industry and infrastructure and sustainable consumption and production (Sustainable Development Goals 7, 8, 9 and 12), as well as targets related to poverty, food security and cities (Sustainable Development Goals 1, 2 and 11), could have substantial positive or negative impacts on nature and therefore on the achievement of other Sustainable Development Goals". In a June 2020 paper published in Nature Communications, a group of scientists argue that "green growth" or "sustainable growth" is a myth: "we have to get away from our obsession with economic growth—we really need to start managing our economies in a way that protects our climate and natural resources, even if this means less, no or even negative growth." They conclude that a change in economic paradigms is imperative to prevent environmental destruction, and suggest a range of ideas from the reformist to the radical, with the latter consisting of degrowth, eco-socialism and eco-anarchism. In June 2020, the official site of one of the organizations promoting degrowth published an article by Vijay Kolinjivadi, an expert in political ecology, arguing that the emergence of COVID-19 is linked to the ecological crisis. The 2019 World Scientists' Warning of a Climate Emergency and its 2021 update have asserted that economic growth is a primary driver of the overexploitation of ecosystems, and to preserve the biosphere and mitigate climate change civilization must, in addition to other fundamental changes including stabilizing population growth and adopting largely plant-based diets, "shift from GDP growth and the pursuit of affluence toward sustaining ecosystems and improving human well-being by prioritizing basic needs and reducing inequality." In an opinion piece published in Al Jazeera, Jason Hickel states that this paper, which has more than 11,000 scientist cosigners, demonstrates that there is a "strong scientific consensus" towards abandoning "GDP as a measure of progress." In a 2022 comment published in Nature, Hickel, Giorgos Kallis, Juliet Schor, Julia Steinberger and others say that both the IPCC and the IPBES "suggest that degrowth policies should be considered in the fight against climate breakdown and biodiversity loss, respectively". Movement Conferences The movement has included international conferences promoted by the network Research & Degrowth (R&D). The First International Conference on Economic Degrowth for Ecological Sustainability and Social Equity in Paris (2008) was a discussion about the financial, social, cultural, demographic, and environmental crisis caused by the deficiencies of capitalism and an explanation of the main principles of degrowth. Further conferences were in Barcelona (2010), Montreal (2012), Venice (2012), Leipzig (2014), Budapest (2016), Malmö (2018), and Zagreb (2023). The 10th International Degrowth Conference will be held in Pontevedra in June 2024. Separately, two conferences have been organised as cross-party initiatives of Members of the European Parliament: the Post-Growth 2018 Conference and the Beyond Growth 2023 Conference, both held in the European Parliament in Brussels. International Degrowth Network The conferences have also been accompanied by informal degrowth assemblies since 2018, to build community between degrowth groups across countries. The 4th Assembly in Zagreb in 2023 discussed a proposal to create a more intentional organisational structure and led to the creation of the International Degrowth Network, which organised the 5th assembly in June 2024. Relation to other social movements The degrowth movement has a variety of relations to other social movements and alternative economic visions, which range from collaboration to partial overlap. The Konzeptwerk Neue Ökonomie (Laboratory for New Economic Ideas), which hosted the 2014 international Degrowth conference in Leipzig, has published a project entitled "Degrowth in movement(s)" in 2017, which maps relationships with 32 other social movements and initiatives. The relation to the environmental justice movement is especially visible. Although not explicitly called degrowth, movements inspired by similar concepts and terminologies can be found around the world, including Buen Vivir in Latin America, the Zapatistas in Mexico, the Kurdish Rojava or Eco-Swaraj in India, and the sufficiency economy in Thailand. The Cuban economic situation has also been of interest to degrowth advocates because its limits on growth were socially imposed (although as a result of geopolitics), and has resulted in positive health changes. Another set of movements the degrowth movement finds synergy with is the wave of initiatives and networks inspired by the commons, where resources are sustainably shared in a decentralised and self-managed manner, instead of through capitalist organization. For example, initiatives inspired by commons could be food cooperatives, open-source platforms, and group management of resources such as energy or water. Commons-based peer production also guides the role of technology in degrowth, where conviviality and socially useful production are prioritised over capital gain. This could happen in the form of cosmolocalism, which offers a framework for localising collaborative forms of production while sharing resources globally as digital commons, to reduce dependence on global value chains. Criticisms, challenges and dilemmas Critiques of degrowth concern the poor study quality of degrowth studies, negative connotation that the term "degrowth" imparts, the misapprehension that growth is seen as unambiguously bad, the challenges and feasibility of a degrowth transition, as well as the entanglement of desirable aspects of modernity with the growth paradigm. Criticisms According to a highly cited scientific paper of environmental economist Jeroen C. J. M. van den Bergh, degrowth is often seen as an ambiguous concept due to its various interpretations, which can lead to confusion rather than a clear and constructive debate on environmental policy. Many interpretations of degrowth do not offer effective strategies for reducing environmental impact or transitioning to a sustainable economy. Additionally, degrowth is unlikely to gain significant social or political support, making it an ineffective strategy for achieving environmental sustainability. Ineffectiveness and better alternatives In his scientific paper, Jeroen C. J. M. van den Bergh concludes that a degrowth strategy, which focuses on reducing the overall scale of the economy or consumption, tends to overlook the significance of changes in production composition and technological innovation. Van den Bergh also highlights that a focus solely on reducing consumption (or consumption degrowth) may lead to rebound effects. For instance, reducing consumption of certain goods and services might result in an increase in spending on other items, as disposable income remains unchanged. Alternatively, it could lead to savings, which would provide additional funds for others to borrow and spend. He emphasizes the importance of (global) environmental policies, such as pricing externalities through taxes or permits, which incentivize behavior changes that reduce environmental impact and which provide essential information for consumers and help manage rebound effects. Effective environmental regulation through pricing is crucial for transitioning from polluting to cleaner consumption patterns. Study quality A 2024 review of degrowth studies over the past 10 years showed that most were of poor quality: almost 90% were opinions rather than analysis, few used quantitative or qualitative data, and even fewer ones used formal modelling; the latter used small samples or a focus on non-representative cases. Also most studies offered subjective policy advice, but lacked policy evaluation and integration with insights from the literature on environmental/climate policies. Negative connotation The use of the term "degrowth" is criticized for being detrimental to the degrowth movement because it could carry a negative connotation, in opposition to the positively perceived "growth". "Growth" is associated with the "up" direction and positive experiences, while "down" generates the opposite associations. Research in political psychology has shown that the initial negative association of a concept, such as of "degrowth" with the negatively perceived "down", can bias how the subsequent information on that concept is integrated at the unconscious level. At the conscious level, degrowth can be interpreted negatively as the contraction of the economy, although this is not the goal of a degrowth transition, but rather one of its expected consequences. In the current economic system, a contraction of the economy is associated with a recession and its ensuing austerity measures, job cuts, or lower salaries. Noam Chomsky commented on the use of the term: "When you say 'degrowth' it frightens people. It's like saying you're going to have to be poorer tomorrow than you are today, and it doesn't mean that." Since "degrowth" contains the term "growth", there is also a risk of the term having a backfire effect, which would reinforce the initial positive attitude toward growth. "Degrowth" is also criticized for being a confusing term, since its aim is not to halt economic growth as the word implies. Instead, "a-growth" is proposed as an alternative concept that emphasizes that growth ceases to be an important policy objective, but that it can still be achieved as a side-effect of environmental and social policies. Systems theoretical critique In stressing the negative rather than the positive side(s) of growth, the majority of degrowth proponents remain focused on (de-)growth, thus giving continued attention to the issue of growth, leading to continued attention to the arguments that sustainable growth is possible. One way to avoid giving attention to growth might be extending from the economic concept of growth, which proponents of both growth and degrowth commonly adopt, to a broader concept of growth that allows for the observation of growth in other sociological characteristics of society. A corresponding "recoding" of "growth-obsessed", capitalist organizations was proposed by Steffen Roth. Marxist critique Traditional Marxists distinguish between two types of value creation: that which is useful to mankind, and that which only serves the purpose of accumulating capital. Traditional Marxists consider that it is the exploitative nature and control of the capitalist production relations that is the determinant and not the quantity. According to Jean Zin, while the justification for degrowth is valid, it is not a solution to the problem. Other Marxist writers have adopted positions close to the de-growth perspective. For example, John Bellamy Foster and Fred Magdoff, in common with David Harvey, Immanuel Wallerstein, Paul Sweezy and others focus on endless capital accumulation as the basic principle and goal of capitalism. This is the source of economic growth and, in the view of these writers, results in an unsustainable growth imperative. Foster and Magdoff develop Marx's own concept of the metabolic rift, something he noted in the exhaustion of soils by capitalist systems of food production, though this is not unique to capitalist systems of food production as seen in the Aral Sea. Many degrowth theories and ideas are based on neo-Marxist theory. Foster emphasizes that degrowth "is not aimed at austerity, but at finding a 'prosperous way down' from our current extractivist, wasteful, ecologically unsustainable, maldeveloped, exploitative, and unequal, class-hierarchical world." Challenges Lack of macroeconomics for sustainability It is reasonable for society to worry about recession as economic growth has been the unanimous goal around the globe in the past decades. However, in some advanced countries, there are attempts to develop a model for a regrowth economy. For instance, the Cool Japan strategy has proven to be instructive for Japan, which has been a static economy for almost decades. Political and social spheres According to some scholars in Sociology, the growth imperative is deeply entrenched in market capitalist societies such that it is necessary for their stability. Moreover, the institutions of modern societies, such as the nation state, welfare, labor market, education, academia, law and finance, have co-evolved with growth to sustain them. A degrowth transition thus requires not only a change of the economic system but of all the systems on which it relies. As most people in modern societies are dependent on those growth-oriented institutions, the challenge of a degrowth transition also lies in individual resistance to move away from growth. Land privatisation Baumann, Alexander and Burdon suggest that "the Degrowth movement needs to give more attention to land and housing costs, which are significant barriers hindering true political and economic agency and any grassroots driven degrowth transition." They claim that land – a necessity like land and air – privatisation creates an absolute economic growth determinant. They point out that even one who is fully committed to degrowth nevertheless has no option but decades of market growth participation to pay rent or mortgage. Because of this, land privatisation is a structural impediment to moving forward that makes degrowth economically and politically unviable. They conclude that without addressing land privatisation (the market's inaugural privatisation – primitive accumulation) the degrowth movement's strategies cannot succeed. Just as land enclosure (privatisation) initiated capitalism (economic growth), degrowth must start with reclaiming land commons. Agriculture When it comes to agriculture, a degrowth society would require a shift from industrial agriculture to less intensive and more sustainable agricultural practices such as permaculture or organic agriculture. Still, it is not clear if any of those alternatives could feed the current and projected global population. In the case of organic agriculture, Germany, for example, would not be able to feed its population under ideal organic yields over all of its arable land without meaningful changes to patterns of consumption, such as reducing meat consumption and food waste. Moreover, labour productivity of non-industrial agriculture is significantly lower due to the reduced use or absence of fossil fuels, which leaves much less labour for other sectors. Potential solutions to this challenge include scaling up approaches such as community-supported agriculture (CSA). Dilemmas Given that modernity has emerged with high levels of energy and material throughput, there is an apparent compromise between desirable aspects of modernity (e.g., social justice, gender equality, long life expectancy, low infant mortality) and unsustainable levels of energy and material use. Some researchers, however, argue that the decline in income inequality and rise in social mobility occurring under capitalism from the late 1940s to the 1960s was a product of the heavy bargaining power of labor unions and increased wealth and income redistribution during that time; while also pointing to the rise in income inequality in the 1970s following the collapse of labor unions and weakening of state welfare measures. Others also argue that modern capitalism maintains gender inequalities by means of advertising, messaging in consumer goods, and social media. Another way of looking at the argument that the development of desirable aspects of modernity require unsustainable energy and material use is through the lens of the Marxist tradition, which relates the superstructure (culture, ideology, institutions) and the base (material conditions of life, division of labor). A degrowth society, with its drastically different material conditions, could produce equally drastic changes in society's cultural and ideological spheres. The political economy of global capitalism has generated a lot of social and environmental bads, such as socioeconomic inequality and ecological devastation, which in turn have also generated a lot of goods through individualization and increased spatial and social mobility. At the same time, some argue the widespread individualization promulgated by a capitalist political economy is a bad due to its undermining of solidarity, aligned with democracy as well as collective, secondary, and primary forms of caring, and simultaneous encouragement of mistrust of others, highly competitive interpersonal relationships, blame of failure on individual shortcomings, prioritization of one's self-interest, and peripheralization of the conceptualization of human work required to create and sustain people. In this view, the widespread individuation resulting from capitalism may impede degrowth measures, requiring a change in actions to benefit society rather than the individual self. Some argue the political economy of capitalism has allowed social emancipation at the level of gender equality, disability, sexuality and anti-racism that has no historical precedent. However, others dispute social emancipation as being a direct product of capitalism or question the emancipation that has resulted. The feminist writer Nancy Holmstrom, for example, argues that capitalism's negative impacts on women outweigh the positive impacts, and women tend to be hurt by the system. In her examination of China following the Chinese Communist Revolution, Holmstrom notes that women were granted state-assisted freedoms to equal education, childcare, healthcare, abortion, marriage, and other social supports. Thus, whether the social emancipation achieved in Western society under capitalism may coexist with degrowth is ambiguous. Doyal and Gough allege that the modern capitalist system is built on the exploitation of female reproductive labor as well as that of the Global South, and sexism and racism are embedded in its structure. Therefore, some theories (such as Eco-Feminism or political ecology) argue that there cannot be equality regarding gender and the hierarchy between the Global North and South within capitalism. The structural properties of growth present another barrier to degrowth as growth shapes and is enforced by institutions, norms, culture, technology, identities, etc. The social ingraining of growth manifests in peoples' aspirations, thinking, bodies, mindsets, and relationships. Together, growth's role in social practices and in socio-economic institutions present unique challenges to the success of the degrowth movement. Another potential barrier to degrowth is the need for a rapid transition to a degrowth society due to climate change and the potential negative impacts of a rapid social transition including disorientation, conflict, and decreased well-being. In the United States, a large barrier to the support of the degrowth movement is the modern education system, including both primary and higher learning institutions. Beginning in the second term of the Reagan administration, the education system in the US was restructured to enforce neoliberal ideology by means of privatization schemes such as commercialization and performance contracting, implementation of standards and accountability measures incentivizing schools to adopt a uniform curriculum, and higher education accreditation and curricula designed to affirm market values and current power structures and avoid critical thought concerning the relations between those in power, ethics, authority, history, and knowledge. The degrowth movement, based on the empirical assumption that resources are finite and growth is limited, clashes with the limitless growth ideology associated with neoliberalism and the market values affirmed in schools, and therefore faces a major social barrier in gaining widespread support in the US. Nevertheless, co-evolving aspects of global capitalism, liberal modernity, and the market society, are closely tied and will be difficult to separate to maintain liberal and cosmopolitan values in a degrowth society. At the same time, the goal of the degrowth movement is progression rather than regression, and researchers point out that neoclassical economic models indicate neither negative nor zero growth would harm economic stability or full employment. Several assert the main barriers to the movement are social and structural factors clashing with implementing degrowth measures. Healthcare It has been pointed out that there is an apparent trade-off between the ability of modern healthcare systems to treat individual bodies to their last breath and the broader global ecological risk of such an energy and resource intensive care. If this trade-off exists, a degrowth society must choose between prioritizing the ecological integrity and the ensuing collective health or maximizing the healthcare provided to individuals. However, many degrowth scholars argue that the current system produces both psychological and physical damage to people. They insist that societal prosperity should be measured by well-being, not GDP.

Sustainable living

Sustainable living describes a lifestyle that attempts to reduce the use of Earth's natural resources by an individual or society. Its practitioners often attempt to reduce their ecological footprint (including their carbon footprint) by altering their home designs and methods of transportation, energy consumption and diet. Its proponents aim to conduct their lives in ways that are consistent with sustainability, naturally balanced, and respectful of humanity's symbiotic relationship with the Earth's natural ecology. The practice and general philosophy of ecological living closely follows the overall principles of sustainable development. One approach to sustainable living, exemplified by small-scale urban transition towns and rural ecovillages, seeks to create self-reliant communities based on principles of simple living, which maximize self-sufficiency, particularly in food production. These principles, on a broader scale, underpin the concept of a bioregional economy. Definition Sustainable living is fundamentally the application of sustainability to lifestyle choices and decisions. One conception of sustainable living expresses what it means in triple-bottom-line terms as meeting present ecological, societal, and economical needs without compromising these factors for future generations. Another broader conception describes sustainable living in terms of four interconnected social domains: economics, ecology, politics, and culture. In the first conception, sustainable living can be described as living within the innate carrying capacities defined by these factors. In the second or Circles of Sustainability conception, sustainable living can be described as negotiating the relationships of needs within limits across all the interconnected domains of social life, including consequences for future human generations and non-human species. Sustainable design and sustainable development are critical factors to sustainable living. Sustainable design encompasses the development of appropriate technology, which is a staple of sustainable living practices. Sustainable development in turn is the use of these technologies in infrastructure. Sustainable architecture and agriculture are the most common examples of this practice. Lester R. Brown, a prominent environmentalist and founder of the Worldwatch Institute and Earth Policy Institute, describes sustainable living in the twenty-first century as "shifting to a renewable energy-based, reuse/recycle economy with a diversified transport system." Anitra Nelson notes that the Degrowth movement has "pointed to ‘growth’ and ‘growth economies’ as the source of inequities and unsustainabilities" with the result that advocates call for "a radical reduction in production and consumption, greater citizen participation in politics, and more diversity, especially within ecological systems and landscapes, along with a flourishing of creativity, care, and commoning — using renewable energy and materials. Derrick Jensen ("the poet-philosopher of the ecological movement"), a celebrated American author, radical environmentalist and prominent critic of mainstream environmentalism argues that "industrial civilization is not and can never be sustainable". From this statement, the natural conclusion is that sustainable living is at odds with industrialization. Thus, practitioners of the philosophy potentially face the challenge of living in an industrial society and adapting alternative norms, technologies, or practices. History 1954 The publication of Living the Good Life by Helen and Scott Nearing marked the beginning of the modern day sustainable living movement. The publication paved the way for the "back-to-the-land movement" in the late 1960s and early 1970s. 1962 The publication of Silent Spring by Rachel Carson marked another major milestone for the sustainability movement. 1972 Donella Meadows wrote the international bestseller The Limits to Growth, which reported on a study of long-term global trends in population, economics and the environment. It sold millions of copies and was translated into 28 languages. 1973 E. F. Schumacher published a collection of essays on shifting towards sustainable living through the appropriate use of technology in his book Small Is Beautiful. 1992–2002 The United Nations held a series of conferences, which focused on increasing sustainability within societies to conserve the Earth's natural resources. The Earth Summit conferences were held in 1992, 1972 and 2002. 2007 the United Nations published Sustainable Consumption and Production, Promoting Climate-Friendly Household Consumption Patterns, which promoted sustainable lifestyles in communities and homes. Shelter On a global scale, shelter is associated with about 25% of the greenhouse gas emissions embodied in household purchases and 26% of households' land use. Sustainable homes are built using sustainable methods, materials, and facilitate green practices, enabling a more sustainable lifestyle. Their construction and maintenance have neutral impacts on the Earth. Often, if necessary, they are close in proximity to essential services such as grocery stores, schools, daycares, work, or public transit making it possible to commit to sustainable transportation choices. Sometimes, they are off-the-grid homes that do not require any public energy, water, or sewer service. If not off-the-grid, sustainable homes may be linked to a grid supplied by a power plant that is using sustainable power sources, buying power as is normal convention. Additionally, sustainable homes may be connected to a grid, but generate their own electricity through renewable means and sell any excess to a utility. There are two common methods to approaching this option: net metering and double metering. Net metering uses the common meter that is installed in most homes, running forward when power is used from the grid, and running backward when power is put into the grid (which allows them to "net" out their total energy use, putting excess energy into the grid when not needed, and using energy from the grid during peak hours, when you may not be able to produce enough immediately). Power companies can quickly purchase the power that is put back into the grid, as it is being produced. Double metering involves installing two meters: one measuring electricity consumed, the other measuring electricity created. Additionally, or in place of selling their renewable energy, sustainable home owners may choose to bank their excess energy by using it to charge batteries. This gives them the option to use the power later during less favorable power-generating times (i.e.: night-time, when there has been no wind, etc.), and to be completely independent of the electrical grid. Sustainably designed (see Sustainable Design) houses are generally sited so as to create as little of a negative impact on the surrounding ecosystem as possible, oriented to the sun so that it creates the best possible microclimate (typically, the long axis of the house or building should be oriented east–west), and provide natural shading or wind barriers where and when needed, among many other considerations. The design of a sustainable shelter affords the options it has later (i.e.: using passive solar lighting and heating, creating temperature buffer zones by adding porches, deep overhangs to help create favorable microclimates, etc.) Sustainably constructed houses involve environmentally friendly management of waste building materials such as recycling and composting, use non-toxic and renewable, recycled, reclaimed, or low-impact production materials that have been created and treated in a sustainable fashion (such as using organic or water-based finishes), use as much locally available materials and tools as possible so as to reduce the need for transportation, and use low-impact production methods (methods that minimize effects on the environment). In April 2019, New York City passed a bill to cut greenhouse gas emissions. The bill's goal was to minimize the climate pollution stemming from the hub that is New York City. It was approved in a 42 to 5 vote, showing a strong favor of the bill. The bill will restrict energy use in larger buildings. The bill imposes greenhouse gas caps on buildings that are over 25,000 square feet. The calculation of the exact cap is done by square feet per building. A similar emission cap had existed already for buildings of 50,000 square feet or more. This bill expands the legislation to cover more large buildings. The bill protects rent-regulated buildings of which there are around 990,000. Due to the implementation of the bill, around 23,000 new green jobs will be created. The bill received support from Mayor Bill de Blasio. New York is taking action based on the recognition that their climate pollution has effects far beyond the city limits of New York. In discussion of a possible new Amazon headquarters in NYC, De Blasio specified that the bill applies to everyone, regardless of prestige. Mayor de Blasio also announced a lawsuit by the city (of New York) to five major oil companies due to their harm on the environment and climate pollution. This also raises the question of the possible closing of the 24 oil and gas burning power plants in New York City, due to the aimed declining use of these sources of energy. With the emission cap, New York will likely see a turn to renewable energy sources. It is possible that these plants will be transitioned to hubs of renewable energy to power the city. This new bill will go into action in three years (2022) and is estimated to cut climate pollution by 40% in eight years (by 2030). Many materials can be considered a "green" material until its background is revealed. Any material that has used toxic or carcinogenic chemicals in its treatment or manufacturing (such as formaldehyde in glues used in woodworking), has traveled extensively from its source or manufacturer, or has been cultivated or harvested in an unsustainable manner might not be considered green. In order for any material to be considered green, it must be resource efficient, not compromise indoor air quality or water conservation, and be energy efficient (both in processing and when in use in the shelter). Resource efficiency can be achieved by using as much recycled content, reusable or recyclable content, materials that employ recycled or recyclable packaging, locally available material, salvaged or remanufactured material, material that employs resource efficient manufacturing, and long-lasting material as possible. Sustainable building materials Some building materials might be considered "sustainable" by some definitions and under certain conditions. For example, wood might be thought of as sustainable if it is grown using sustainable forest management, processed using sustainable energy, delivered by sustainable transport, etc. Under different conditions, however, it might not be considered as sustainable. The following materials might be considered as sustainable under certain conditions, based on a Life-cycle assessment: Adobe Bamboo Cellulose insulation Clay Cob Composite wood (when made from reclaimed hardwood sawdust and reclaimed or recycled plastic) Compressed earth block Cordwood Cork Hemp Insulating concrete forms Lime render Linoleum Lumber from Forest Stewardship Council approved sources Natural Rubber Natural fiber (coir, wool, jute, etc.) Organic cotton insulation Papercrete Rammed earth Reclaimed stone Reclaimed brick Recycled metal Recycled concrete Recycled paper Soy-based adhesive Soy insulation Straw Bale Structural insulated panel Wood Insulation of a sustainable home is important because of the energy it conserves throughout the life of the home. Well insulated walls and lofts using green materials are a must as it reduces or, in combination with a house that is well designed, eliminates the need for heating and cooling altogether. Installation of insulation varies according to the type of insulation being used. Typically, lofts are insulated by strips of insulating material laid between rafters. Walls with cavities are done in much the same manner. For walls that do not have cavities behind them, solid-wall insulation may be necessary which can decrease internal space and can be expensive to install. Energy-efficient windows are another important factor in insulation. Simply assuring that windows (and doors) are well sealed greatly reduces energy loss in a home. Double or Triple glazed windows are the typical method to insulating windows, trapping gas or creating a vacuum between two or three panes of glass allowing heat to be trapped inside or out. Low-emissivity or Low-E glass is another option for window insulation. It is a coating on windowpanes of a thin, transparent layer of metal oxide and works by reflecting heat back to its source, keeping the interior warm during the winter and cool during the summer. Simply hanging heavy-backed curtains in front of windows may also help their insulation. "Superwindows," mentioned in Natural Capitalism: Creating the Next Industrial Revolution, became available in the 1980s and use a combination of many available technologies, including two to three transparent low-e coatings, multiple panes of glass, and a heavy gas filling. Although more expensive, they are said to be able to insulate four and a half times better than a typical double-glazed windows. Equipping roofs with highly reflective material (such as aluminum) increases a roof's albedo and will help reduce the amount of heat it absorbs, hence, the amount of energy needed to cool the building it is on. Green roofs or "living roofs" are a popular choice for thermally insulating a building. They are also popular for their ability to catch storm-water runoff and, when in the broader picture of a community, reduce the heat island effect (see urban heat island) thereby reducing energy costs of the entire area. It is arguable that they are able to replace the physical "footprint" that the building creates, helping reduce the adverse environmental impacts of the building's presence. Energy efficiency and water conservation are also major considerations in sustainable housing. If using appliances, computers, HVAC systems, electronics, or lighting the sustainable-minded often look for an Energy Star label, which is government-backed and holds stricter regulations in energy and water efficiency than is required by law. Ideally, a sustainable shelter should be able to completely run the appliances it uses using renewable energy and should strive to have a neutral impact on the Earth's water sources Greywater, including water from washing machines, sinks, showers, and baths may be reused in landscape irrigation and toilets as a method of water conservation. Likewise, rainwater harvesting from storm-water runoff is also a sustainable method to conserve water use in a sustainable shelter. Sustainable Urban Drainage Systems replicate the natural systems that clean water in wildlife and implement them in a city's drainage system so as to minimize contaminated water and unnatural rates of runoff into the environment. See related articles in: LEED (Leadership in Energy and Environmental Design) and also it is one of the most important factor of sustainable lifestyle. Power As mentioned under Shelter, some sustainable households may choose to produce their own renewable energy, while others may choose to purchase it through the grid from a power company that harnesses sustainable sources (also mentioned previously are the methods of metering the production and consumption of electricity in a household). Purchasing sustainable energy, however, may simply not be possible in some locations due to its limited availability. 6 out of the 50 states in the US do not offer green energy, for example. For those that do, its consumers typically buy a fixed amount or a percentage of their monthly consumption from a company of their choice and the bought green energy is fed into the entire national grid. Technically, in this case, the green energy is not being fed directly to the household that buys it. In this case, it is possible that the amount of green electricity that the buying household receives is a small fraction of their total incoming electricity. This may or may not depend on the amount being purchased. The purpose of buying green electricity is to support their utility's effort in producing sustainable energy. Producing sustainable energy on an individual household or community basis is much more flexible, but can still be limited in the richness of the sources that the location may afford (some locations may not be rich in renewable energy sources while others may have an abundance of it). When generating renewable energy and feeding it back into the grid (in participating countries such as the US and Germany), producing households are typically paid at least the full standard electricity rate by their utility and are also given separate renewable energy credits that they can then sell to their utility, additionally (utilities are interested in buying these renewable energy credits because it allows them to claim that they produce renewable energy). In some special cases, producing households may be paid up to four times the standard electricity rate, but this is not common. Solar power harnesses the energy of the sun to make electricity. Two typical methods for converting solar energy into electricity are photo-voltaic cells that are organized into panels and concentrated solar power, which uses mirrors to concentrate sunlight to either heat a fluid that runs an electrical generator via a steam turbine or heat engine, or to simply cast onto photo-voltaic cells. The energy created by photo-voltaic cells is a direct current and has to be converted to alternating current before it can be used in a household. At this point, users can choose to either store this direct current in batteries for later use, or use an AC/DC inverter for immediate use. To get the best out of a solar panel, the angle of incidence of the sun should be between 20 and 50 degrees. Solar power via photo-voltaic cells are usually the most expensive method to harnessing renewable energy, but is falling in price as technology advances and public interest increases. It has the advantages of being portable, easy to use on an individual basis, readily available for government grants and incentives, and being flexible regarding location (though it is most efficient when used in hot, arid areas since they tend to be the most sunny). For those that are lucky, affordable rental schemes may be found. Concentrated solar power plants are typically used on more of a community scale rather than an individual household scale, because of the amount of energy they are able to harness but can be done on an individual scale with a parabolic reflector. Solar thermal energy is harnessed by collecting direct heat from the sun. One of the most common ways that this method is used by households is through solar water heating. In a broad perspective, these systems involve well insulated tanks for storage and collectors, are either passive or active systems (active systems have pumps that continuously circulate water through the collectors and storage tank) and, in active systems, involve either directly heating the water that will be used or heating a non-freezing heat-transfer fluid that then heats the water that will be used. Passive systems are cheaper than active systems since they do not require a pumping system (instead, they take advantage of the natural movement of hot water rising above cold water to cycle the water being used through the collector and storage tank). Other methods of harnessing solar power are solar space heating (for heating internal building spaces), solar drying (for drying wood chips, fruits, grains, etc.), solar cookers, solar distillers, and other passive solar technologies (simply, harnessing sunlight without any mechanical means). Wind power is harnessed through turbines, set on tall towers (typically 20’ or 6m with 10‘ or 3m diameter blades for an individual household's needs) that power a generator that creates electricity. They typically require an average of wind speed of 9 mi/hr (14 km/h) to be worth their investment (as prescribed by the US Department of Energy), and are capable of paying for themselves within their lifetimes. Wind turbines in urban areas usually need to be mounted at least 30’ (10m) in the air to receive enough wind and to be void of nearby obstructions (such as neighboring buildings). Mounting a wind turbine may also require permission from authorities. Wind turbines have been criticized for the noise they produce, their appearance, and the argument that they can affect the migratory patterns of birds (their blades obstruct passage in the sky). Wind turbines are much more feasible for those living in rural areas and are one of the most cost-effective forms of renewable energy per kilowatt, approaching the cost of fossil fuels, and have quick paybacks. For those that have a body of water flowing at an adequate speed (or falling from an adequate height) on their property, hydroelectricity may be an option. On a large scale, hydroelectricity, in the form of dams, has adverse environmental and social impacts. When on a small scale, however, in the form of single turbines, hydroelectricity is very sustainable. Single water turbines or even a group of single turbines are not environmentally or socially disruptive. On an individual household basis, single turbines are the probably the only economically feasible route (but can have high paybacks and is one of the most efficient methods of renewable energy production). It is more common for an eco-village to use this method rather than a singular household. Geothermal energy production involves harnessing the hot water or steam below the earth's surface, in reservoirs, to produce energy. Because the hot water or steam that is used is reinjected back into the reservoir, this source is considered sustainable. However, those that plan on getting their electricity from this source should be aware that there is controversy over the lifespan of each geothermal reservoir as some believe that their lifespans are naturally limited (they cool down over time, making geothermal energy production there eventually impossible). This method is often large scale as the system required to harness geothermal energy can be complex and requires deep drilling equipment. There do exist small individual scale geothermal operations, however, which harness reservoirs very close to the Earth's surface, avoiding the need for extensive drilling and sometimes even taking advantage of lakes or ponds where there is already a depression. In this case, the heat is captured and sent to a geothermal heat pump system located inside the shelter or facility that needs it (often, this heat is used directly to warm a greenhouse during the colder months). Although geothermal energy is available everywhere on Earth, practicality and cost-effectiveness varies, directly related to the depth required to reach reservoirs. Places such as the Philippines, Hawaii, Alaska, Iceland, California, and Nevada have geothermal reservoirs closer to the Earth's surface, making its production cost-effective. Biomass power is created when any biological matter is burned as fuel. As with the case of using green materials in a household, it is best to use as much locally available material as possible so as to reduce the carbon footprint created by transportation. Although burning biomass for fuel releases carbon dioxide, sulfur compounds, and nitrogen compounds into the atmosphere, a major concern in a sustainable lifestyle, the amount that is released is sustainable (it will not contribute to a rise in carbon dioxide levels in the atmosphere). This is because the biological matter that is being burned releases the same amount of carbon dioxide that it consumed during its lifetime. However, burning biodiesel and bioethanol (see biofuel) when created from virgin material, is increasingly controversial and may or may not be considered sustainable because it inadvertently increases global poverty, the clearing of more land for new agriculture fields (the source of the biofuel is also the same source of food), and may use unsustainable growing methods (such as the use of environmentally harmful pesticides and fertilizers). List of organic matter that can be burned for fuel Bagasse Biogas Manure Stover Straw Used vegetable oil Wood Digestion of organic material to produce methane is becoming an increasingly popular method of biomass energy production. Materials such as waste sludge can be digested to release methane gas that can then be burnt to produce electricity. Methane gas is also a natural by-product of landfills, full of decomposing waste, and can be harnessed here to produce electricity as well. The advantage in burning methane gas is that is prevents the methane from being released into the atmosphere, exacerbating the greenhouse effect. Although this method of biomass energy production is typically large scale (done in landfills), it can be done on a smaller individual or community scale as well. Food Globally, food accounts for 48% and 90% of household environmental impacts on land and water resources respectively, with consumption of meat, dairy and processed food rising quickly with income. Environmental impacts of industrial agriculture Industrial agricultural production is highly resource and energy intensive. Industrial agriculture systems typically require heavy irrigation, extensive pesticide and fertilizer application, intensive tillage, concentrated monoculture production, and other continual inputs. As a result of these industrial farming conditions, today's mounting environmental stresses are further exacerbated. These stresses include: declining water tables, chemical leaching, chemical runoff, soil erosion, land degradation, loss in biodiversity, and other ecological concerns. Conventional food distribution and long distance transport Conventional food distribution and long-distance transport are additionally resource and energy exhaustive. Substantial climate-disrupting carbon emissions, boosted by the transport of food over long distances, are of growing concern as the world faces such global crisis as natural resource depletion, peak oil and climate change. "The average American meal currently costs about 1500 miles, and takes about 10 calories of oil and other fossil fuels to produce a single calorie of food." Local and seasonal foods A more sustainable means of acquiring food is to purchase locally and seasonally. Buying food from local farmers reduces carbon output, caused by long-distance food transport, and stimulates the local economy. Local, small-scale farming operations also typically utilize more sustainable methods of agriculture than conventional industrial farming systems such as decreased tillage, nutrient cycling, fostered biodiversity and reduced chemical pesticide and fertilizer applications. Adapting a more regional, seasonally based diet is more sustainable as it entails purchasing less energy and resource demanding produce that naturally grow within a local area and require no long-distance transport. These vegetables and fruits are also grown and harvested within their suitable growing season. Thus, seasonal food farming does not require energy intensive greenhouse production, extensive irrigation, plastic packaging and long-distance transport from importing non-regional foods, and other environmental stressors. Local, seasonal produce is typically fresher, unprocessed and argued to be more nutritious. Local produce also contains less to no chemical residues from applications required for long-distance shipping and handling. Farmers' markets, public events where local small-scale farmers gather and sell their produce, are a good source for obtaining local food and knowledge about local farming productions. As well as promoting localization of food, farmers markets are a central gathering place for community interaction. Another way to become involved in regional food distribution is by joining a local community-supported agriculture (CSA). A CSA consists of a community of growers and consumers who pledge to support a farming operation while equally sharing the risks and benefits of food production. CSA's usually involve a system of weekly pick-ups of locally farmed vegetables and fruits, sometimes including dairy products, meat and special food items such as baked goods. Considering the previously noted rising environmental crisis, the United States and much of the world is facing immense vulnerability to famine. Local food production ensures food security if potential transportation disruptions and climatic, economical, and sociopolitical disasters were to occur. Reducing meat consumption Industrial meat production also involves high environmental costs such as land degradation, soil erosion and depletion of natural resources, especially pertaining to water and food. Mass meat production increase the amount of methane in the atmosphere. For more information on the environmental impact of meat production and consumption, see the ethics of eating meat. Reducing meat consumption, perhaps to a few meals a week, or adopting a vegetarian or vegan diet, alleviates the demand for environmentally damaging industrial meat production. Buying and consuming organically raised, free range or grass fed meat is another alternative towards more sustainable meat consumption. Organic farming Purchasing and supporting organic products is another fundamental contribution to sustainable living. Organic farming is a rapidly emerging trend in the food industry and in the web of sustainability. According to the USDA National Organic Standards Board (NOSB), organic agriculture is defined as "an ecological production management system that promotes and enhances biodiversity, biological cycles, and soil biological activity. It is based on minimal use of off-farm inputs and on management practices that restore, maintain, or enhance ecological harmony. The primary goal of organic agriculture is to optimize the health and productivity of interdependent communities of soil life, plants, animals and people." Upon sustaining these goals, organic agriculture uses techniques such as crop rotation, permaculture, compost, green manure and biological pest control. In addition, organic farming prohibits or strictly limits the use of manufactured fertilizers and pesticides, plant growth regulators such as hormones, livestock antibiotics, food additives and genetically modified organisms. Organically farmed products include vegetables, fruit, grains, herbs, meat, dairy, eggs, fibers, and flowers. See organic certification for more information. Urban gardening In addition to local, small-scale farms, there has been a recent emergence in urban agriculture expanding from community gardens to private home gardens. With this trend, both farmers and ordinary people are becoming involved in food production. A network of urban farming systems helps to further ensure regional food security and encourages self-sufficiency and cooperative interdependence within communities. With every bite of food raised from urban gardens, negative environmental impacts are reduced in numerous ways. For instance, vegetables and fruits raised within small-scale gardens and farms are not grown with tremendous applications of nitrogen fertilizer required for industrial agricultural operations. The nitrogen fertilizers cause toxic chemical leaching and runoff that enters our water tables. Nitrogen fertilizer also produces nitrous oxide, a more damaging greenhouse gas than carbon dioxide. Local, community-grown food also requires no imported, long-distance transport which further depletes our fossil fuel reserves. In developing more efficiency per land acre, urban gardens can be started in a wide variety of areas: in vacant lots, public parks, private yards, church and school yards, on roof tops (roof-top gardens), and many other places. Communities can work together in changing zoning limitations in order for public and private gardens to be permissible. Aesthetically pleasing edible landscaping plants can also be incorporated into city landscaping such as blueberry bushes, grapevines trained on an arbor, pecan trees, etc. With as small a scale as home or community farming, sustainable and organic farming methods can easily be utilized. Such sustainable, organic farming techniques include: composting, biological pest control, crop rotation, mulching, drip irrigation, nutrient cycling and permaculture. For more information on sustainable farming systems, see sustainable agriculture. Food preservation and storage Preserving and storing foods reduces reliance on long-distance transported food and the market industry. Home-grown foods can be preserved and stored outside of their growing season and continually consumed throughout the year, enhancing self-sufficiency and independence from the supermarket. Food can be preserved and saved by dehydration, freezing, vacuum packing, canning, bottling, pickling and jellying. For more information, see food preservation. Transportation With rising concerns over non-renewable energy source usage and climate change caused by carbon emissions, the phase-out of fossil fuel vehicles is becoming more and more important to the conversation of sustainability. Zero-emission urban transport systems that foster mobility, accessible public transportation and healthier urban environments are needed. Such urban transport systems should consist of rail transport, electric buses, bicycle pathways, provision for human-powered transport and pedestrian walkways. Public transport systems such as underground rail systems and bus transit systems shift huge numbers of people away from reliance on car dependency and dramatically reduce the rate of carbon emissions caused by automobile transport. In comparison to automobiles, bicycles are a paragon of energy efficient personal transportation with the bicycle roughly 50 times more energy efficient than driving. Bicycles increase mobility while alleviating congestion, lowering air and noise pollution, and increasing physical exercise. Most importantly, they do not emit climate-damaging carbon dioxide. Bike-sharing programs are beginning to boom throughout the world and are modeled in leading cities such as Paris, Amsterdam and London. Bike-sharing programs offer kiosks and docking stations that supply hundreds to thousands of bikes for rental throughout a city through small deposits or affordable memberships. A recent boom has occurred in electric bikes especially in China and other Asian countries. Electric bikes are similar to electric cars in that they are battery-powered and can be plugged into the provincial electric grid for recharging as needed. In contrast to electric cars, electric bikes do not directly use any fossil fuels. Adequate sustainable urban transportation is dependent upon proper city transport infrastructure and planning that incorporates efficient public transit along with bicycle and pedestrian-friendly pathways. Water A major factor of sustainable living involves that which no human can live without, water. Unsustainable water use has far reaching implications for humankind. Currently, humans use one-fourth of the Earth's total fresh water in natural circulation, and over half the accessible runoff. Additionally, population growth and water demand is ever increasing. Thus, it is necessary to use available water more efficiently. In sustainable living, one can use water more sustainably through a series of simple, everyday measures. These measures involve considering indoor home appliance efficiency, outdoor water use, and daily water use awareness. Indoor home appliances Housing and commercial buildings account for 12 percent of America's freshwater withdrawals. A typical American single family home uses about per person per day indoors. This use can be reduced by simple alterations in behavior and upgrades to appliance quality. Toilets Toilets accounted for almost 30% of residential indoor water use in the United States in 1999. One flush of a standard U.S. toilet requires more water than most individuals, and many families, in the world use for all their needs in an entire day. A home's toilet water sustainability can be improved in one of two ways: improving the current toilet or installing a more efficient toilet. To improve the current toilet, one possible method is to put weighted plastic bottles in the toilet tank. Also, there are inexpensive tank banks or float booster available for purchase. A tank bank is a plastic bag to be filled with water and hung in the toilet tank. A float booster attaches underneath the float ball of pre-1986 three and a half gallon capacity toilets. It allows these toilets to operate at the same valve and float setting but significantly reduces their water level, saving between one and one and a third gallons of water per flush. A major waste of water in existing toilets is leaks. A slow toilet leak is undetectable to the eye, but can waste hundreds of gallons each month. One way to check this is to put food dye in the tank, and to see if the water in the toilet bowl turns the same color. In the event of a leaky flapper, one can replace it with an adjustable toilet flapper, which allows self-adjustment of the amount of water per flush. In installing a new toilet there are a number of options to obtain the most water efficient model. A low flush toilet uses one to two gallons per flush. Traditionally, toilets use three to five gallons per flush. If an eighteen-liter per flush toilet is removed and a six-liter per flush toilet is put in its place, 70% of the water flushed will be saved while the overall indoor water use by will be reduced by 30%. It is possible to have a toilet that uses no water. A composting toilet treats human waste through composting and dehydration, producing a valuable soil additive. These toilets feature a two-compartment bowl to separate urine from feces. The urine can be collected or sold as fertilizer. The feces can be dried and bagged or composted. These toilets cost scarcely more than regularly installed toilets and do not require a sewer hookup. In addition to providing valuable fertilizer, these toilets are highly sustainable because they save sewage collection and treatment, as well as lessen agricultural costs and improve topsoil. Additionally, one can reduce toilet water sustainability by limiting total toilet flushing. For instance, instead of flushing small wastes, such as tissues, one can dispose of these items in the trash or compost. Showers On average, showers were 18% of U.S. indoor water use in 1999, at per minute traditionally in America. A simple method to reduce this use is to switch to low-flow, high-performance showerheads. These showerheads use only 1.0–1.5 gpm or less. An alternative to replacing the showerhead is to install a converter. This device arrests a running shower upon reaching the desired temperature. Solar water heaters can be used to obtain optimal water temperature, and are more sustainable because they reduce dependence on fossil fuels. To lessen excess water use, water pipes can be insulated with pre-slit foam pipe insulation. This insulation decreases hot water generation time. A simple, straightforward method to conserve water when showering is to take shorter showers. One method to accomplish this is to turn off the water when it is not necessary (such as while lathering) and resuming the shower when water is necessary. This can be facilitated when the plumbing or showerhead allow turning off the water without disrupting the desired temperature setting (common in the UK but not the United States). Dishwashers and sinks On average, sinks were 15% of U.S. indoor water use in 1999. There are, however, easy methods to rectify excessive water loss. Available for purchase is a screw-on aerator. This device works by combining water with air thus generating a frothy substance with greater perceived volume, reducing water use by half. Additionally, there is a flip-valve available that allows flow to be turned off and back on at the previously reached temperature. Finally, a laminar flow device creates a 1.5–2.4 gpm stream of water that reduces water use by half, but can be turned to normal water level when optimal. In addition to buying the above devices, one can live more sustainably by checking sinks for leaks, and fixing these links if they exist. According to the EPA, "A small drip from a worn faucet washer can waste 20 gallons of water per day, while larger leaks can waste hundreds of gallons". When washing dishes by hand, it is not necessary to leave the water running for rinsing, and it is more efficient to rinse dishes simultaneously. On average, dishwashing consumes 1% of indoor water use. When using a dishwasher, water can be conserved by only running the machine when it is full. Some have a "low flow" setting to use less water per wash cycle. Enzymatic detergents clean dishes more efficiently and more successfully with a smaller amount of water at a lower temperature. Washing machines On average, 23% of U.S. indoor water use in 1999 was due to clothes washing. In contrast to other machines, American washing machines have changed little to become more sustainable. A typical washing machine has a vertical-axis design, in which clothes are agitated in a tubful of water. Horizontal-axis machines, in contrast, put less water into the bottom of the rub and rotate clothes through it. These machines are more efficient in terms of soap use and clothing stability. Outdoor water use There are a number of ways one can incorporate a personal yard, roof, and garden in more sustainable living. While conserving water is a major element of sustainability, so is sequestering water. Conserving water In planning a yard and garden space, it is most sustainable to consider the plants, soil, and available water. Drought resistant shrubs, plants, and grasses require a smaller amount of water in comparison to more traditional species. Additionally, native plants (as opposed to herbaceous perennials) will use a smaller supply of water and have a heightened resistance to plant diseases of the area. Xeriscaping is a technique that selects drought-tolerant plants and accounts for endemic features such as slope, soil type, and native plant range. It can reduce landscape water use by 50 – 70%, while providing habitat space for wildlife. Plants on slopes help reduce runoff by slowing and absorbing accumulated rainfall. Grouping plants by watering needs further reduces water waste. After planting, placing a circumference of mulch surrounding plants functions to lessen evaporation. To do this, firmly press two to four inches of organic matter along the plant's dripline. This prevents water runoff. When watering, consider the range of sprinklers; watering paved areas is unnecessary. Additionally, to conserve the maximum amount of water, watering should be carried out during early mornings on non-windy days to reduce water loss to evaporation. Drip-irrigation systems and soaker hoses are a more sustainable alternative to the traditional sprinkler system. Drip-irrigation systems employ small gaps at standard distances in a hose, leading to the slow trickle of water droplets which percolate the soil over a protracted period. These systems use 30 – 50% less water than conventional methods. Soaker hoses help to reduce water use by up to 90%. They connect to a garden hose and lay along the row of plants under a layer of mulch. A layer of organic material added to the soil helps to increase its absorption and water retention; previously planted areas can be covered with compost. In caring for a lawn, there are a number of measures that can increase the sustainability of lawn maintenance techniques. A primary aspect of lawn care is watering. To conserve water, it is important to only water when necessary, and to deep soak when watering. Additionally, a lawn may be left to go dormant, renewing after a dry spell to its original vitality. Sequestering water A common method of water sequestrations is rainwater harvesting, which incorporates the collection and storage of rain. Primarily, the rain is obtained from a roof, and stored on the ground in catchment tanks. Water sequestration varies based on extent, cost, and complexity. A simple method involves a single barrel at the bottom of a downspout, while a more complex method involves multiple tanks. It is highly sustainable to use stored water in place of purified water for activities such as irrigation and flushing toilets. Additionally, using stored rainwater reduces the amount of runoff pollution, picked up from roofs and pavements that would normally enter streams through storm drains. The following equation can be used to estimate annual water supply: Collection area (square feet) × Rainfall (inch/year) / 12 (inch/foot) = Cubic Feet of Water/Year Cubic Feet/Year × 7.43 (Gallons/Cubic Foot) = Gallons/year Note, however, this calculation does not account for losses such as evaporation or leakage. Greywater systems function in sequestering used indoor water, such as laundry, bath and sink water, and filtering it for reuse. Greywater can be reused in irrigation and toilet flushing. There are two types of greywater systems: gravity fed manual systems and package systems. The manual systems do not require electricity but may require a larger yard space. The package systems require electricity but are self-contained and can be installed indoors. Waste As populations and resource demands climb, waste production contributes to emissions of carbon dioxide, leaching of hazardous materials into the soil and waterways, and methane emissions. In America alone, over the course of a decade, of American resources will have been transformed into nonproductive wastes and gases. Thus, a crucial component of sustainable living is being waste conscious. One can do this by reducing waste, reusing commodities, and recycling. There are a number of ways to reduce waste in sustainable living. Two methods to reduce paper waste are canceling junk mail like credit card and insurance offers and direct mail marketing and changing monthly paper statements to paperless emails. Junk mail alone accounted for 1.72 million tons of landfill waste in 2009. Another method to reduce waste is to buy in bulk, reducing packaging materials. Preventing food waste can limit the amount of organic waste sent to landfills producing the powerful greenhouse gas methane. Another example of waste reduction involves being cognizant of purchasing excessive amounts when buying materials with limited use like cans of paint. Non-hazardous or less hazardous alternatives can also limit the toxicity of waste. By reusing materials, one lives more sustainably by not contributing to the addition of waste to landfills. Reusing saves natural resources by decreasing the necessity of raw material extraction. For example, reusable bags can reduce the amount of waste created by grocery shopping eliminating the need to create and ship plastic bags and the need to manage their disposal and recycling or polluting effects. Recycling, a process that breaks down used items into raw materials to make new materials, is a particularly useful means of contributing to the renewal of goods. Recycling incorporates three primary processes; collection and processing, manufacturing, and purchasing recycled products. A natural example of recycling involves using food waste as compost to enrich the quality of soil, which can be carried out at home or locally with community composting. An offshoot of recycling, upcycling, strives to convert material into something of similar or greater value in its second life. By integrating measures of reusing, reducing, and recycling one can effectively reduce personal waste and use materials in a more sustainable manner. Reproductive choices Though it is not always included in discussions of sustainable living, some consider reproductive choices to be a key part of sustainable living. Reproductive choices refers, in this case, to the number of children that an individual has, whether they are conceived biologically or adopted. Some researchers have claimed that for people living in wealthy, high-consumption countries such as the United States, having fewer children is by far the most effective way to decrease one's carbon footprint, and one's ecological footprint more broadly. However, the scholarship that has led to this claim has been questioned, as has the misleading way that it's often been presented in popular newspaper and web articles. Some ethicists and environmental activists have made similar arguments about the need for a "small family ethic" and research has found that in some countries, these ecological concerns are leading some people to report having fewer children than they would otherwise, or no children at all. However, there have been multiple critiques of the idea that having fewer children is part of a sustainable lifestyle. Some argue that it is an example of the kind of Malthusian thinking that has led to coercion and violence in the past (including forced sterilizations and forced abortions), and that it might lead to similar policies that deny women reproductive freedom in the future. Additionally, research has found that some environmentalists consider having children, and even having more children than they might otherwise, to be a part of sustainable living. They assert that parenting can be an important way that individuals can exert a positive environmental influence, by educating the next generation and as a way to remain engaged in one's commitment to environmental action. Provision, supply and expenditure in general A study that reviewed 217 analyses of on-the-market products and services and analyzed existing alternatives to mainstream food, holidays, and furnishings, concluded that total greenhouse gas emissions by Swedes could be lowered by as of 2021 up to 36–38 % if consumers – without a decrease in total estimated expenditure or considerations of self-interest rationale – instead were to obtain those they – using available data – could assess to be more sustainable. Provision, supply/availability, product development/success/price, comparative benefits as well as incentives, purposes/demands and effects of expenditure-choices are part of or embedded in the human neuro-socioeconomic system and therefore overall largely beyond the control of an individual seeking to make rational and ethical choices within it even if all relevant life-cycle assessment/product and manufacturing information was available to this consumer . and it leads the consumer See also Buddhist economics Circles of Sustainability Citizen Science, cleanup projects that people can take part in.

Environmental resource management

Environmental resource management or environmental management is the management of the interaction and impact of human societies on the environment. It is not, as the phrase might suggest, the management of the environment itself. Environmental resources management aims to ensure that ecosystem services are protected and maintained for future human generations, and also maintain ecosystem integrity through considering ethical, economic, and scientific (ecological) variables. Environmental resource management tries to identify factors between meeting needs and protecting resources. It is thus linked to environmental protection, resource management, sustainability, integrated landscape management, natural resource management, fisheries management, forest management, wildlife management, environmental management systems, and others. Significance Environmental resource management is an issue of increasing concern, as reflected in its prevalence in several texts influencing global sociopolitical frameworks such as the Brundtland Commission's Our Common Future, which highlighted the integrated nature of the environment and international development, and the Worldwatch Institute's annual State of the World reports. The environment determines the nature of people, animals, plants, and places around the Earth, affecting behaviour, religion, culture and economic practices. Scope Environmental resource management can be viewed from a variety of perspectives. It involves the management of all components of the biophysical environment, both living (biotic) and non-living (abiotic), and the relationships among all living species and their habitats. The environment also involves the relationships of the human environment, such as the social, cultural, and economic environment, with the biophysical environment. The essential aspects of environmental resource management are ethical, economical, social, and technological. These underlie principles and help make decisions. The concept of environmental determinism, probabilism, and possibilism are significant in the concept of environmental resource management. Environmental resource management covers many areas in science, including geography, biology, social sciences, political sciences, public policy, ecology, physics, chemistry, sociology, psychology, and physiology. Environmental resource management as a practice and discourse (across these areas) is also the object of study in the social sciences. Aspects Ethical Environmental resource management strategies are intrinsically driven by conceptions of human-nature relationships. Ethical aspects involve the cultural and social issues relating to the environment, and dealing with changes to it. "All human activities take place in the context of certain types of relationships between society and the bio-physical world (the rest of nature)," and so, there is a great significance in understanding the ethical values of different groups around the world. Broadly speaking, two schools of thought exist in environmental ethics: Anthropocentrism and Ecocentrism, each influencing a broad spectrum of environmental resource management styles along a continuum. These styles perceive "...different evidence, imperatives, and problems, and prescribe different solutions, strategies, technologies, roles for economic sectors, culture, governments, and ethics, etc." Anthropocentrism Anthropocentrism, "an inclination to evaluate reality exclusively in terms of human values," is an ethic reflected in the major interpretations of Western religions and the dominant economic paradigms of the industrialised world. Anthropocentrism looks at nature as existing solely for the benefit of humans, and as a commodity to use for the good of humanity and to improve human quality of life. Anthropocentric environmental resource management is therefore not the conservation of the environment solely for the environment's sake, but rather the conservation of the environment, and ecosystem structure, for humans' sake. Ecocentrism Ecocentrists believe in the intrinsic value of nature while maintaining that human beings must use and even exploit nature to survive and live. It is this fine ethical line that ecocentrists navigate between fair use and abuse. At an extreme of the ethical scale, ecocentrism includes philosophies such as ecofeminism and deep ecology, which evolved as a reaction to dominant anthropocentric paradigms. "In its current form, it is an attempt to synthesize many old and some new philosophical attitudes about the relationship between nature and human activity, with particular emphasis on ethical, social, and spiritual aspects that have been downplayed in the dominant economic worldview." Economics Main article: Economics The economy functions within and is dependent upon goods and services provided by natural ecosystems. The role of the environment is recognized in both classical economics and neoclassical economics theories, yet the environment was a lower priority in economic policies from 1950 to 1980 due to emphasis from policy makers on economic growth. With the prevalence of environmental problems, many economists embraced the notion that, "If environmental sustainability must coexist for economic sustainability, then the overall system must [permit] identification of an equilibrium between the environment and the economy." As such, economic policy makers began to incorporate the functions of the natural environment – or natural capital – particularly as a sink for wastes and for the provision of raw materials and amenities. Debate continues among economists as to how to account for natural capital, specifically whether resources can be replaced through knowledge and technology, or whether the environment is a closed system that cannot be replenished and is finite. Economic models influence environmental resource management, in that management policies reflect beliefs about natural capital scarcity. For someone who believes natural capital is infinite and easily substituted, environmental management is irrelevant to the economy. For example, economic paradigms based on neoclassical models of closed economic systems are primarily concerned with resource scarcity and thus prescribe legalizing the environment as an economic externality for an environmental resource management strategy. This approach has often been termed 'Command-and-control'. Colby has identified trends in the development of economic paradigms, among them, a shift towards more ecological economics since the 1990s. Ecology There are many definitions of the field of science commonly called ecology. A typical one is "the branch of biology dealing with the relations and interactions between organisms and their environment, including other organisms." "The pairing of significant uncertainty about the behaviour and response of ecological systems with urgent calls for near-term action constitutes a difficult reality, and a common lament" for many environmental resource managers. Scientific analysis of the environment deals with several dimensions of ecological uncertainty. These include: structural uncertainty resulting from the misidentification, or lack of information pertaining to the relationships between ecological variables; parameter uncertainty referring to "uncertainty associated with parameter values that are not known precisely but can be assessed and reported in terms of the likelihood…of experiencing a defined range of outcomes"; and stochastic uncertainty stemming from chance or unrelated factors. Adaptive management is considered a useful framework for dealing with situations of high levels of uncertainty though it is not without its detractors. A common scientific concept and impetus behind environmental resource management is carrying capacity. Simply put, carrying capacity refers to the maximum number of organisms a particular resource can sustain. The concept of carrying capacity, whilst understood by many cultures over history, has its roots in Malthusian theory. An example is visible in the EU Water Framework Directive. However, "it is argued that Western scientific knowledge ... is often insufficient to deal with the full complexity of the interplay of variables in environmental resource management. These concerns have been recently addressed by a shift in environmental resource management approaches to incorporate different knowledge systems including traditional knowledge, reflected in approaches such as adaptive co-management community-based natural resource management and transitions management among others. Sustainability Sustainability in environmental resource management involves managing economic, social, and ecological systems both within and outside an organizational entity so it can sustain itself and the system it exists in. In context, sustainability implies that rather than competing for endless growth on a finite planet, development improves quality of life without necessarily consuming more resources. Sustainably managing environmental resources requires organizational change that instills sustainability values that portrays these values outwardly from all levels and reinforces them to surrounding stakeholders. The result should be a symbiotic relationship between the sustaining organization, community, and environment. Many drivers compel environmental resource management to take sustainability issues into account. Today's economic paradigms do not protect the natural environment, yet they deepen human dependency on biodiversity and ecosystem services. Ecologically, massive environmental degradation and climate change threaten the stability of ecological systems that humanity depends on. Socially, an increasing gap between rich and poor and the global North–South divide denies many access to basic human needs, rights, and education, leading to further environmental destruction. The planet's unstable condition is caused by many anthropogenic sources. As an exceptionally powerful contributing factor to social and environmental change, the modern organisation has the potential to apply environmental resource management with sustainability principles to achieve highly effective outcomes. To achieve sustainable development with environmental resource management an organisation should work within sustainability principles, including social and environmental accountability, long-term planning; a strong, shared vision; a holistic focus; devolved and consensus decision making; broad stakeholder engagement and justice; transparency measures; trust; and flexibility. Current paradigm shifts To adjust to today's environment of quick social and ecological changes, some organizations have begun to experiment with new tools and concepts. Those that are more traditional and stick to hierarchical decision making have difficulty dealing with the demand for lateral decision making that supports effective participation. Whether it be a matter of ethics or just strategic advantage organizations are internalizing sustainability principles. Some of the world's largest and most profitable corporations are shifting to sustainable environmental resource management: Ford, Toyota, BMW, Honda, Shell, Du Port, Sta toil, Swiss Re, Hewlett-Packard, and Unilever, among others. An extensive study by the Boston Consulting Group reaching 1,560 business leaders from diverse regions, job positions, expertise in sustainability, industries, and sizes of organizations, revealed the many benefits of sustainable practice as well as its viability. Although the sustainability of environmental resource management has improved, corporate sustainability, for one, has yet to reach the majority of global companies operating in the markets. The three major barriers to preventing organizations from shifting towards sustainable practice with environmental resource management are not understanding what sustainability is; having difficulty modeling an economically viable case for the switch; and having a flawed execution plan, or a lack thereof. Therefore, the most important part of shifting an organization to adopt sustainability in environmental resource management would be to create a shared vision and understanding of what sustainability is for that particular organization and to clarify the business case. Stakeholders Public sector The public sector comprises the general government sector plus all public corporations including the central bank. In environmental resource management the public sector is responsible for administering natural resource management and implementing environmental protection legislation. The traditional role of the public sector in environmental resource management is to provide professional judgement through skilled technicians on behalf of the public. With the increase of intractable environmental problems, the public sector has been led to examine alternative paradigms for managing environmental resources. This has resulted in the public sector working collaboratively with other sectors (including other governments, private and civil) to encourage sustainable natural resource management behaviours. Private sector The private sector comprises private corporations and non-profit institutions serving households. The private sector's traditional role in environmental resource management is that of the recovery of natural resources. Such private sector recovery groups include mining (minerals and petroleum), forestry and fishery organisations. Environmental resource management undertaken by the private sectors varies dependent upon the resource type, that being renewable or non-renewable and private and common resources (also see Tragedy of the Commons). Environmental managers from the private sector also need skills to manage collaboration within a dynamic social and political environment. Civil society Civil society comprises associations in which societies voluntarily organise themselves and which represent a wide range of interests and ties. These can include community-based organisations, indigenous peoples' organisations and non-government organisations (NGOs). Functioning through strong public pressure, civil society can exercise their legal rights against the implementation of resource management plans, particularly land management plans. The aim of civil society in environmental resource management is to be included in the decision-making process by means of public participation. Public participation can be an effective strategy to invoke a sense of social responsibility of natural resources. Tools As with all management functions, effective management tools, standards, and systems are required. An environmental management standard or system or protocol attempts to reduce environmental impact as measured by some objective criteria. The ISO 14001 standard is the most widely used standard for environmental risk management and is closely aligned to the European Eco-Management and Audit Scheme (EMAS). As a common auditing standard, the ISO 19011 standard explains how to combine this with quality management. Other environmental management systems (EMS) tend to be based on the ISO 14001 standard and many extend it in various ways: The Green Dragon Environmental Management Standard is a five-level EMS designed for smaller organisations for whom ISO 14001 may be too onerous and for larger organisations who wish to implement ISO 14001 in a more manageable step-by-step approach, BS 8555 is a phased standard that can help smaller companies move to ISO 14001 in six manageable steps, The Natural Step focuses on basic sustainability criteria and helps focus engineering on reducing use of materials or energy use that is unsustainable in the long term, Natural Capitalism advises using accounting reform and a general biomimicry and industrial ecology approach to do the same thing, US Environmental Protection Agency has many further terms and standards that it defines as appropriate to large-scale EMS, The UN and World Bank has encouraged adopting a "natural capital" measurement and management framework. Other strategies exist that rely on making simple distinctions rather than building top-down management "systems" using performance audits and full cost accounting. For instance, Ecological Intelligent Design divides products into consumables, service products or durables and unsaleables – toxic products that no one should buy, or in many cases, do not realize they are buying. By eliminating the unsaleables from the comprehensive outcome of any purchase, better environmental resource management is achieved without systems. Another example that diverges from top-down management is the implementation of community based co-management systems of governance. An example of this is community based subsistence fishing areas, such as is implemented in Ha'ena, Hawaii. Community based systems of governance allow for the communities who most directly interact with the resource and who are most deeply impacted by the overexploitation of said resource to make the decisions regarding its management, thus empowering local communities and more effectively managing resources. Recent successful cases have put forward the notion of integrated management. It shares a wider approach and stresses out the importance of interdisciplinary assessment. It is an interesting notion that might not be adaptable to all cases. Case Study: Kissidougou, Guinea (Fairhead, Leach) Kissidougou, Guinea’s dry season brings about fires in the open grass fires which defoliate the few trees in the savanna. There are villages within this savanna surrounded by “islands” of forests, allowing for forts, hiding, rituals, protection from wind and fire, and shade for crops. According to scholars and researchers in the region during the late-19th and 20th centuries, there was a steady decline in tree cover. This led to colonial Guinea’s implementation of policies, including the switch of upland to swamp farming; bush-fire control; protection of certain species and land; and tree planting in villages. These policies were carried out in the form of permits, fines, and military repression. But, Kissidougou villagers claim their ancestors’ established these islands. Many maps and letters evidence France’s occupation of Guinea, as well as Kissidougou’s past landscape. During the 1780s to 1860s “the whole country [was] prairie.” James Fairhead and Melissa Leach, both environmental anthropologists at the University of Sussex, claim the state’s environmental analyses “casts into question the relationships between society, demography, and environment.” With this, they reformed the state’s narratives: Local land use can be both vegetation enriching and degrading; combined effect on resource management is greater than the sum of their parts; there is evidence of increased population correlating to an increase in forest cover. Fairhead and Leach support the enabling of policy and socioeconomic conditions in which local resource management conglomerates can act effectively. In Kissidougou, there is evidence that local powers and community efforts shaped the island forests that shape the savanna’s landscape.

Resource

Resource refers to all the materials available in our environment which are technologically accessible, economically feasible and culturally sustainable and help us to satisfy our needs and wants. Resources can broadly be classified according to their availability as renewable or national and international resources. An item may become a resource with technology. The benefits of resource utilization may include increased wealth, proper functioning of a system, or enhanced well. From a human perspective, a regular resource is anything to satisfy human needs and wants. The concept of resources has been developed across many established areas of work, in economics, biology and ecology, computer science, management, and human resources for example - linked to the concepts of competition, sustainability, conservation, and stewardship. In application within human society, commercial or non-commercial factors require resource allocation through resource management. The concept of resources can also be tied to the direction of leadership over resources; this may include human resources issues, for which leaders are responsible, in managing, supporting, or directing those matters and the resulting necessary actions. For example, in the cases of professional groups, innovative leaders and technical experts in archiving expertise, academic management, association management, business management, healthcare management, military management, public administration, spiritual leadership and social networking administration. Definition of size asymmetry Resource competition can vary from completely symmetric (all individuals receive the same amount of resources, irrespective of their size, known also as scramble competition) to perfectly size symmetric (all individuals exploit the same amount of resource per unit biomass) to absolutely size asymmetric (the largest individuals exploit all the available resource). Economic versus biological There are three fundamental differences between economic versus ecological views: 1) the economic resource definition is human-centered (anthropocentric) and the biological or ecological resource definition is nature-centered (biocentric or ecocentric); 2) the economic view includes desire along with necessity, whereas the biological view is about basic biological needs; and 3) economic systems are based on markets of currency exchanged for goods and services, whereas biological systems are based on natural processes of growth, maintenance, and reproduction. Computer resources A computer resource is any physical or virtual component of limited availability within a computer or information management system. Computer resources include means for input, processing, output, communication, and storage. Natural Natural resources are derived from the environment. Many natural resources are essential for human survival, while others are used to satisfy human desire. Conservation is the management of natural resources with the goal of sustainability. Natural resources may be further classified in different ways. Resources can be categorized based on origin: Abiotic resources comprise non-living things (e.g., land, water, air, and minerals such as gold, iron, copper, silver). Biotic resources are obtained from the biosphere. Forests and their products, animals, birds and their products, fish and other marine organisms are important examples. Minerals such as coal and petroleum are sometimes included in this category because they were formed from fossilized organic matter, over long periods. Natural resources are also categorized based on the stage of development: Potential resources are known to exist and may be used in the future. For example, petroleum may exist in many parts of India and Kuwait that have sedimentary rocks, but until the time it is actually drilled out and put into use, it remains a potential resource. Actual resources are those, that have been surveyed, their quantity and quality determined, and are being used in present times. For example, petroleum and natural gas are actively being obtained from the Mumbai High Fields. The development of an actual resource, such as wood processing depends on the technology available and the cost involved. That part of the actual resource that can be developed profitably with the available technology is known as a reserve resource, while that part that can not be developed profitably due to a lack of technology is known as a stock resource. Natural resources can be categorized based on renewability: Non-renewable resources are formed over very long geological periods. Minerals and fossils are included in this category. Since their formation rate is extremely slow, they cannot be replenished, once they are depleted. Even though metals can be recycled and reused, whereas petroleum and gas cannot, they are still considered non-renewable resources. Renewable resources, such as forests and fisheries, can be replenished or reproduced relatively quickly. The highest rate at which a resource can be used sustainably is the sustainable yield. Some resources, such as sunlight, air, and wind, are called perpetual resources because they are available continuously, though at a limited rate. Human consumption does not affect their quantity. Many renewable resources can be depleted by human use, but may also be replenished, thus maintaining a flow. Some of these, such as crops, take a short time for renewal; others, such as water, take a comparatively longer time, while others, such as forests, need even longer periods. Depending upon the speed and quantity of consumption, overconsumption can lead to depletion or the total and everlasting destruction of a resource. Important examples are agricultural areas, fish and other animals, forests, healthy water and soil, cultivated and natural landscapes. Such conditionally renewable resources are sometimes classified as a third kind of resource or as a subtype of renewable resources. Conditionally renewable resources are presently subject to excess human consumption and the only sustainable long-term use of such resources is within the so-called zero ecological footprint, where humans use less than the Earth's ecological capacity to regenerate. Natural resources are also categorized based on distribution: Ubiquitous resources are found everywhere (for example, air, light, and water). Localized resources are found only in certain parts of the world (for example metal ores and geothermal power). Actual vs. potential natural resources are distinguished as follows: Actual resources are those resources whose location and quantity are known and we have the technology to exploit and use them. Potential resources are those of which we have insufficient knowledge or do not have the technology to exploit them at present. Based on ownership, resources can be classified as individual, community, national, and international. Labour or human resources In economics, labor or human resources refers to the human work in the production of goods and rendering of services. Human resources can be defined in terms of skills, energy, talent, abilities, or knowledge. In a project management context, human resources are those employees responsible for undertaking the activities defined in the project plan. Capital or infrastructure In economics, capital goods or capital are "those durable produced goods that are in turn used as productive inputs for further production" of goods and services. A typical example is the machinery used in a factory. At the macroeconomic level, "the nation's capital stock includes buildings, equipment, software, and inventories during a given year." Capitals are the most important economic resource. Tangible versus intangible Whereas, tangible resources such as equipment have an actual physical existence, intangible resources such as corporate images, brands and patents, and other intellectual properties exist in abstraction. Use and sustainable development Typically resources cannot be consumed in their original form, but rather through resource development they must be processed into more usable commodities and usable things. The demand for resources is increasing as economies develop. There are marked differences in resource distribution and associated economic inequality between regions or countries, with developed countries using more natural resources than developing countries. Sustainable development is a pattern of resource use, that aims to meet human needs while preserving the environment. Sustainable development means that we should exploit our resources carefully to meet our present requirement without compromising the ability of future generations to meet their own needs. The practice of the three R's – reduce, reuse, and recycle must be followed to save and extend the availability of resources. Various problems are related to the usage of resources: Environmental degradation Over-consumption Resource curse Resource depletion Tragedy of the commons Various benefits can result from the wise usage of resources: Economic growth Ethical consumerism Prosperity Quality of life Sustainability Wealth See also Natural resource management Resource-based view Waste management References Further reading Elizabeth Kolbert, "Needful Things: The raw materials for the world we've built come at a cost" (largely based on Ed Conway, Material World: The Six Raw Materials That Shape Modern Civilization, Knopf, 2023; Vince Beiser, The World in a Grain; and Chip Colwell, So Much Stuff: How Humans Discovered Tools, Invented Meaning, and Made More of Everything, Chicago), The New Yorker, 30 October 2023, pp. 20–23. Kolbert mainly discusses the importance to modern civilization, and the finite sources of, six raw materials: high-purity quartz (needed to produce silicon chips), sand, iron, copper, petroleum (which Conway lumps together with another fossil fuel, natural gas), and lithium. Kolbert summarizes archeologist Colwell's review of the evolution of technology, which has ended up giving the Global North a superabundance of "stuff," at an unsustainable cost to the world's environment and reserves of raw materials.

Environmentalism

Environmentalism or environmental rights is a broad philosophy, ideology, and social movement about supporting life, habitats, and surroundings. While environmentalism focuses more on the environmental and nature-related aspects of green ideology and politics, ecologism combines the ideology of social ecology and environmentalism. Ecologism is more commonly used in continental European languages, while environmentalism is more commonly used in English but the words have slightly different connotations. Environmentalism advocates the preservation, restoration and improvement of the natural environment and critical earth system elements or processes such as the climate, and may be referred to as a movement to control pollution or protect plant and animal diversity. For this reason, concepts such as a land ethics, environmental ethics, biodiversity, ecology, and the biophilia hypothesis figure predominantly. The environmentalist movement encompasses various approaches to addressing environmental issues, including free market environmentalism, evangelical environmentalism, and the environmental conservation movement. At its crux, environmentalism is an attempt to balance relations between humans and the various natural systems on which they depend in such a way that all the components are accorded a proper degree of sustainability. The exact measures and outcomes of this balance is controversial and there are many different ways for environmental concerns to be expressed in practice. Environmentalism and environmental concerns are often represented by the colour green, but this association has been appropriated by the marketing industries for the tactic known as greenwashing. Environmentalism is opposed by anti-environmentalism, which says that the Earth is less fragile than some environmentalists maintain, and portrays environmentalism as overreacting to the human contribution to climate change or opposing human advancement. Definitions Environmentalism denotes a social movement that seeks to influence the political process by lobbying, activism, and education in order to protect natural resources and ecosystems. An environmentalist is a person who may speak out about our natural environment and the sustainable management of its resources through changes in public policy or individual behaviour. This may include supporting practices such as informed consumption, conservation initiatives, investment in renewable resources, improved efficiencies in the materials economy, transitioning to new accounting paradigms such as ecological economics, renewing and revitalizing our connections with non-human life or even opting to have one less child to reduce consumption and pressure on resources. In various ways (for example, grassroots activism and protests), environmentalists and environmental organisations seek to give the natural world a stronger voice in human affairs. In general terms, environmentalists advocate the sustainable management of resources, and the protection (and restoration, when necessary) of the natural environment through changes in public policy and individual behaviour. In its recognition of humanity as a participant in ecosystems, the movement is centered around ecology, health, and human rights. History A concern for environmental protection has recurred in diverse forms, in different parts of the world, throughout history. The earliest ideas of environmental protectionism can be found in Jainism, a religion from ancient India revived by Mahavira in the 6th century BC. Jainism offers a view that is in many ways compatible with core values associated with environmental activism, such as the protection of life by nonviolence, which could form a strong ecological ethos for global protection of the environment. Mahavira's teachings on the symbiosis between all living beings—as well as the five elements of earth, water, air, fire, and space—are core to environmental thought today. In West Asia, the Caliph Abu Bakr in the 630s AD commanded his army to "Bring no harm to the trees, nor burn them with fire," and to "Slay not any of the enemy's flock, save for your food." Various Islamic medical treatises during the 9th to 13th centuries dealt with environmentalism and environmental science, including the issue of pollution. The authors of such treatises included Al-Kindi, Qusta ibn Luqa, Al-Razi, Ibn Al-Jazzar, al-Tamimi, al-Masihi, Avicenna, Ali ibn Ridwan, Ibn Jumay, Isaac Israeli ben Solomon, Abd-el-latif, Ibn al-Quff, and Ibn al-Nafis. Their works covered a number of subjects related to pollution, such as air pollution, water pollution, soil contamination, and the mishandling of municipal solid waste. They also included assessments of certain localities' environmental impact. In Europe, King Edward I of England banned the burning and sale of "sea-coal" in 1272 by proclamation in London, after its smoke had become a prevalent annoyance throughout the city. This fuel, common in London due to the local scarcity of wood, was given this early name because it could be found washed up on some shores, from where it was carted away on a wheelbarrow. Early environmental legislation The origins of the environmental movement lay in the response to increasing levels of smoke pollution in the atmosphere during the Industrial Revolution. The emergence of great factories and the concomitant immense growth in coal consumption gave rise to an unprecedented level of air pollution in industrial centers; after 1900 the large volume of industrial chemical discharges added to the growing load of untreated human waste. The first large-scale, modern environmental laws came in the form of Britain's Alkali Acts, passed in 1863, to regulate the deleterious air pollution (gaseous hydrochloric acid) given off by the Leblanc process, used to produce soda ash. An Alkali inspector and four sub-inspectors were appointed to curb this pollution. The inspectorate's responsibilities were gradually expanded, culminating in the Alkali Order 1958 which placed all major heavy industries that emitted smoke, grit, dust and fumes under supervision. In industrial cities, local experts and reformers, especially after 1890, took the lead in identifying environmental degradation and pollution, and initiating grass-roots movements to demand and achieve reforms. Typically the highest priority went to water and air pollution. The Coal Smoke Abatement Society was formed in 1898 making it one of the oldest environmental NGOs. It was founded by artist Sir William Blake Richmond, frustrated with the pall cast by coal smoke. Although there were earlier pieces of legislation, the Public Health Act 1875 required all furnaces and fireplaces to consume their own smoke. It also provided for sanctions against factories that emitted large amounts of black smoke. This law's provisions were extended in 1926 with the Smoke Abatement Act to include other emissions, such as soot, ash, and gritty particles, and to empower local authorities to impose their own regulations. It was only under the impetus of the Great Smog of 1952 in London, which almost brought the city to a standstill and may have caused upward of 6,000 deaths, that the Clean Air Act 1956 was passed and airborne pollution in the city was first tackled. Financial incentives were offered to householders to replace open coal fires with alternatives (such as installing gas fires) or those who preferred, to burn coke instead (a byproduct of town gas production) which produces minimal smoke. 'Smoke control areas' were introduced in some towns and cities where only smokeless fuels could be burnt and power stations were relocated away from cities. The act formed an important impetus to modern environmentalism and caused a rethinking of the dangers of environmental degradation to people's quality of life. The late 19th century also saw the passage of the first wildlife conservation laws. The zoologist Alfred Newton published a series of investigations into the Desirability of establishing a 'Close-time' for the preservation of indigenous animals between 1872 and 1903. His advocacy for legislation to protect animals from hunting during the mating season led to the formation of the Royal Society for the Protection of Birds and influenced the passage of the Sea Birds Preservation Act in 1869 as the first nature protection law in the world. During the Spanish Revolution, anarchist-controlled territories undertook several environmental reforms, which were possibly the largest in the world at the time. Daniel Guerin notes that anarchist territories would diversify crops, extend irrigation, initiate reforestation, start tree nurseries and help to establish naturist communities. Once there was a link discovered between air pollution and tuberculosis, the CNT shut down several metal factories. First environmental movements Early interest in the environment was a feature of the Romantic movement in the early 19th century. One of the earliest modern pronouncements on thinking about human industrial advancement and its influence on the environment was written by Japanese geographer, educator, philosopher and author Tsunesaburo Makiguchi in his 1903 publication Jinsei Chirigaku (A Geography of Human Life). In Britain the poet William Wordsworth travelled extensively in the Lake District and wrote that it is a "sort of national property in which every man has a right and interest who has an eye to perceive and a heart to enjoy". Systematic efforts on behalf of the environment only began in the late 19th century; it grew out of the amenity movement in Britain in the 1870s, which was a reaction to industrialisation, the growth of cities, and worsening air and water pollution. Starting with the formation of the Commons Preservation Society in 1865, the movement championed rural preservation against the encroachments of industrialisation. Robert Hunter, solicitor for the society, worked with Hardwicke Rawnsley, Octavia Hill, and John Ruskin to lead a successful campaign to prevent the construction of railways to carry slate from the quarries, which would have ruined the unspoiled valleys of Newlands and Ennerdale. This success led to the formation of the Lake District Defence Society (later to become The Friends of the Lake District). Peter Kropotkin wrote about ecology in economics, agricultural science, conservation, ethology, criminology, urban planning, geography, geology and biology. He observed in Swiss and Siberian glaciers that they had been slowly melting since the dawn of the industrial revolution, possibly making him one of the first predictors for climate change. He also observed the damage done from deforestation and hunting. Kropotkin's writings would become influential in the 1970s and became a major inspiration for the intentional community movement as well as his ideas becoming the basis for the theory of social ecology. In 1893 Hill, Hunter and Rawnsley agreed to set up a national body to coordinate environmental conservation efforts across the country; the "National Trust for Places of Historic Interest or Natural Beauty" was formally inaugurated in 1894. The organisation obtained secure footing through the 1907 National Trust Bill, which gave the trust the status of a statutory corporation. and the bill was passed in August 1907. An early "Back-to-Nature" movement, which anticipated the romantic ideal of modern environmentalism, was advocated by intellectuals such as John Ruskin, William Morris, George Bernard Shaw and Edward Carpenter, who were all against consumerism, pollution and other activities that were harmful to the natural world. The movement was a reaction to the urban conditions of the industrial towns, where sanitation was awful, pollution levels intolerable and housing terribly cramped. Idealists championed the rural life as a mythical utopia and advocated a return to it. John Ruskin argued that people should return to a "small piece of English ground, beautiful, peaceful, and fruitful. We will have no steam engines upon it ... we will have plenty of flowers and vegetables ... we will have some music and poetry; the children will learn to dance to it and sing it." Practical ventures in the establishment of small cooperative farms were even attempted and old rural traditions, without the "taint of manufacture or the canker of artificiality", were enthusiastically revived, including the Morris dance and the maypole. These ideas also inspired various environmental groups in the UK, such as the Royal Society for the Protection of Birds, established in 1889 by Emily Williamson as a protest group to campaign for greater protection for the indigenous birds of the island. The Society attracted growing support from the suburban middle-classes as well as support from many other influential figures, such as the ornithologist Professor Alfred Newton. By 1900, public support for the organisation had grown, and it had over 25,000 members. The garden city movement incorporated many environmental concerns into its urban planning manifesto; the Socialist League and The Clarion movement also began to advocate measures of nature conservation. The movement in the United States began in the late 19th century, out of concerns for protecting the natural resources of the West, with individuals such as John Muir and Henry David Thoreau making key philosophical contributions. Thoreau was interested in peoples' relationship with nature and studied this by living close to nature in a simple life. He published his experiences in the book Walden, which argues that people should become intimately close with nature. Muir came to believe in nature's inherent right, especially after spending time hiking in Yosemite Valley and studying both the ecology and geology. He successfully lobbied congress to form Yosemite National Park and went on to set up the Sierra Club in 1892. The conservationist principles as well as the belief in an inherent right of nature were to become the bedrock of modern environmentalism. In the 20th century, environmental ideas continued to grow in popularity and recognition. Efforts were starting to be made to save some wildlife, particularly the American bison. The death of the last passenger pigeon as well as the endangerment of the American bison helped to focus the minds of conservationists and to popularise their concerns. In 1916, the National Park Service was founded by US President Woodrow Wilson. The Forestry Commission was set up in 1919 in Britain to increase the amount of woodland in Britain by buying land for afforestation and reforestation. The commission was also tasked with promoting forestry and the production of timber for trade. During the 1920s the Commission focused on acquiring land to begin planting out new forests; much of the land was previously used for agricultural purposes. By 1939 the Forestry Commission was the largest landowner in Britain. During the 1930s the Nazis had elements that were supportive of animal rights, zoos and wildlife, and took several measures to ensure their protection. In 1933 the government created a stringent animal-protection law and in 1934, (The Reich Hunting Law) was enacted which limited hunting. Several Nazis were environmentalists (notably Rudolf Hess), and species protection and animal welfare were significant issues in the regime. In 1935, the regime enacted the "Reich Nature Protection Act". The concept of the (best translated as the "perpetual forest") which included concepts such as forest management and protection was promoted and efforts were also made to curb air pollution. In 1949, A Sand County Almanac by Aldo Leopold was published. It explained Leopold's belief that humankind should have moral respect for the environment and that it is unethical to harm it. The book is sometimes called the most influential book on conservation. Throughout the 1950s, 1960s, 1970s and beyond, photography was used to enhance public awareness of the need for protecting land and recruiting members to environmental organisations. David Brower, Ansel Adams and Nancy Newhall created the Sierra Club Exhibit Format Series, which helped raise public environmental awareness and brought a rapidly increasing flood of new members to the Sierra Club and to the environmental movement in general. This Is Dinosaur, edited by Wallace Stegner with photographs by Martin Litton and Philip Hyde, prevented the building of dams within Dinosaur National Monument by becoming part of a new kind of activism called environmentalism that combined the conservationist ideals of Thoreau, Leopold and Muir with hard-hitting advertising, lobbying, book distribution, letter writing campaigns, and more. The powerful use of photography in addition to the written word for conservation dated back to the creation of Yosemite National Park, when photographs persuaded Abraham Lincoln to preserve the beautiful glacier carved landscape for all time. The Sierra Club Exhibit Format Series galvanised public opposition to building dams in the Grand Canyon and protected many other national treasures. The Sierra Club often led a coalition of many environmental groups including the Wilderness Society and many others. After a focus on preserving wilderness in the 1950s and 1960s, the Sierra Club and other groups broadened their focus to include such issues as air and water pollution, population concern, and curbing the exploitation of natural resources. The prevailing belief regarding the origins of early environmentalism suggests that it emerged as a local response to the adverse impacts of industrialization in Western nations and communities. In terms of conservation efforts, there is a widespread view that the conservation movement began as a predominantly elite concern in North America, focusing on the preservation of local natural areas. A less prevailing view, however, attributes the roots of early environmentalism to a growing public concern about the influence of Western economic forces, particularly in connection with colonization, on tropical environments. Richard Grove, in a 1990 report, points out that little attention has been given to the significance of the colonial experience, particularly the European colonial experience, in shaping early European environmentalism. Grove argues that as European colonization expanded, so did the European interaction with land and indigenous people, providing Europeans with an awareness of the destructive consequences of their economic and colonial activities on the newly "discovered" lands. As global trade expanded through colonization, the European concept of nature underwent a transformation, with the foreign tropical environments of their conquests evolving into romantic symbols of idyllic landscapes that required care and protection by Europeans. Examples of this impact of colonization on the Western mindset can be found in prominent cultural references, such as William Shakespeare's play "The Tempest" and Andrew Marvell's poem "Bermoothes." Although this newfound self-awareness among Europeans about the destructive impacts of colonization on the environment did not halt the expansion of colonization itself, it did pave the way for a different approach to colonization – one focused on the preservation and protection of foreign natural resources. This phenomenon can be linked to the emergence of Edenic thinking, or the quest for Eden on Earth. This quest to locate Eden gained prominence in the 15th century, coinciding with colonization, and fostered the belief that newly "discovered" lands, especially tropical ones, had the potential to be heavenly paradises. Post-war expansion In 1962, Silent Spring by American biologist Rachel Carson was published. The book cataloged the environmental impacts of the indiscriminate spraying of DDT in the US and questioned the logic of releasing large amounts of chemicals into the environment without fully understanding their effects on human health and ecology. The book suggested that DDT and other pesticides may cause cancer and that their agricultural use was a threat to wildlife, particularly birds. The resulting public concern led to the creation of the United States Environmental Protection Agency in 1970 which subsequently banned the agricultural use of DDT in the US in 1972. The limited use of DDT in disease vector control continues to this day in certain parts of the world and remains controversial. The book's legacy was to produce a far greater awareness of environmental issues and interest into how people affect the environment. With this new interest in environment came interest in problems such as air pollution and petroleum spills, and environmental interest grew. New pressure groups formed, notably Greenpeace and Friends of the Earth (US), as well as notable local organisations such as the Wyoming Outdoor Council, which was founded in 1967. From 1962 to 1998, the environmental movement founded 772 national organizations in the United States. In the 1970s, the environmental movement gained rapid speed around the world as a productive outgrowth of the counterculture movement. The world's first political parties to campaign on a predominantly environmental platform were the United Tasmania Group of Tasmania, Australia, and the Values Party of New Zealand. The first green party in Europe was the Popular Movement for the Environment, founded in 1972 in the Swiss canton of Neuchâtel. The first national green party in Europe was PEOPLE, founded in Britain in February 1973, which eventually turned into the Ecology Party, and then the Green Party. Protection of the environment also became important in the developing world; the Chipko movement was formed in India under the influence of Mhatmas Gandhi and they set up peaceful resistance to deforestation by literally hugging trees (leading to the term "tree huggers"). Their peaceful methods of protest and slogan "ecology is permanent economy" were very influential. Another milestone in the movement was the creation of Earth Day. Earth Day was first observed in San Francisco and other cities on 21 March 1970, the first day of spring. It was created to give awareness to environmental issues. On 21 March 1971, United Nations Secretary-General U Thant spoke of a spaceship Earth on Earth Day, hereby referring to the ecosystem services the earth supplies to us, and hence our obligation to protect it (and with it, ourselves). Earth Day is now coordinated globally by the Earth Day Network, and is celebrated in more than 192 countries every year. The UN's first major conference on international environmental issues, the United Nations Conference on the Human Environment (also known as the Stockholm Conference), was held on 5–16 June 1972. It marked a turning point in the development of international environmental politics. By the mid-1970s, many felt that people were on the edge of environmental catastrophe. The back-to-the-land movement started to form and ideas of environmental ethics joined with anti-Vietnam War sentiments and other political issues. These individuals lived outside normal society and started to take on some of the more radical environmental theories such as deep ecology. Around this time more mainstream environmentalism was starting to show force with the signing of the Endangered Species Act in 1973 and the formation of CITES in 1975. Significant amendments were also enacted to the United States Clean Air Act and Clean Water Act. In 1979, James Lovelock, a British scientist, published Gaia: A new look at life on Earth, which put forth the Gaia hypothesis; it proposes that life on earth can be understood as a single organism. This became an important part of the Deep Green ideology. Throughout the rest of the history of environmentalism there has been debate and argument between more radical followers of this Deep Green ideology and more mainstream environmentalists. 21st century and beyond Environmentalism continues to evolve to face up to new issues such as global warming, overpopulation, genetic engineering, and plastic pollution. Research demonstrates a precipitous decline in the US public's interest in 19 different areas of environmental concern. Americans are less likely to be actively participating in an environmental movement or organisation and more likely to identify as "unsympathetic" to an environmental movement than in 2000. This is likely a lingering factor of the Great Recession in 2008. Since 2005, the percentage of Americans agreeing that the environment should be given priority over economic growth has dropped 10 points; in contrast, those feeling that growth should be given priority "even if the environment suffers to some extent" has risen 12 percent. Nevertheless, a recent National Geographic survey indicated strong desire for commitment across a dozen countries, indicating a majority were in favour of more than half of the Earth's land surface being protected. New forms of ecoactivism Tree sitting is a form of activism in which the protester sits in a tree in an attempt to stop the removal of a tree or to impede the demolition of an area with the longest and most famous tree-sitter being Julia Butterfly Hill, who spent 738 days in a California Redwood, saving a three-acre tract of forest. Also notable is the Yellow Finch tree sit, which was a 932-day blockade of the Mountain Valley Pipeline from 2018 to 2021. Sit-ins can be used to encourage social change, such as the Greensboro sit-ins, a series of protests in 1960 to stop racial segregation, but can also be used in ecoactivism, as in the Dakota Access Pipeline Protest. Before the Syrian civil war, Rojava had been ecologically damaged by monoculture, oil extraction, damming of rivers, deforestation, drought, topsoil loss and general pollution. The DFNS launched a campaign titled 'Make Rojava Green Again' (a parody of Make America Great Again) which is attempting to provide renewable energy to communities (especially solar energy), reforestation, protecting water sources, planting gardens, promoting urban agriculture, creating wildlife reserves, water recycling, beekeeping, expanding public transportation and promoting environmental awareness within their communities. The Rebel Zapatista Autonomous Municipalities are firmly environmentalist and have stopped the extraction of oil, uranium, timber and metal from the Lacandon Jungle and stopped the use of pesticides and chemical fertilisers in farming. The CIPO-RFM has engaged in sabotage and direct action against wind farms, shrimp farms, eucalyptus plantations and the timber industry. They have also set up corn and coffee worker cooperatives and built schools and hospitals to help the local populations. They have also created a network of autonomous community radio stations to educate people about dangers to the environment and inform the surrounding communities about new industrial projects that would destroy more land. In 2001, the CIPO-RFM defeated the construction of a highway that was part of Plan Puebla Panama. Environmental movement The environmental movement (a term that sometimes includes the conservation and green movements) is a diverse scientific, social, and political movement. Though the movement is represented by a range of organisations, because of the inclusion of environmentalism in the classroom curriculum, the environmental movement has a younger demographic than is common in other social movements (see green seniors). Environmentalism as a movement covers broad areas of institutional oppression, including for example: consumption of ecosystems and natural resources into waste, dumping waste into disadvantaged communities, air pollution, water pollution, weak infrastructure, exposure of organic life to toxins, mono-culture, anti-polythene drive (jhola movement) and various other focuses. Because of these divisions, the environmental movement can be categorized into these primary focuses: environmental science, environmental activism, environmental advocacy, and environmental justice. Free market environmentalism Free market environmentalism is a theory that argues that the free market, property rights, and tort law provide the best tools to preserve the health and sustainability of the environment. It considers environmental stewardship to be natural, as well as the expulsion of polluters and other aggressors through individual and class action. Evangelical environmentalism Evangelical environmentalism is an environmental movement in the United States in which some Evangelicals have emphasized biblical mandates concerning humanity's role as steward and subsequent responsibility for the care taking of Creation. While the movement has focused on different environmental issues, it is best known for its focus of addressing climate action from a biblically grounded theological perspective. This movement is controversial among some non-Christian environmentalists due to its rooting in a specific religion. Preservation and conservation Environmental preservation in the United States and other parts of the world, including Australia, is viewed as the setting aside of natural resources to prevent damage caused by contact with humans or by certain human activities, such as logging, mining, hunting, and fishing, often to replace them with new human activities such as tourism and recreation. Regulations and laws may be enacted for the preservation of natural resources. Exergy and availability of resources Thermodynamic derived environmentalism is based on the second law of thermodynamics, minimization of exergy disruption (or entropy generation)and the concept of availability. It moves from he milestone work of Jan Szargut who emphasized the relation between exergy and availability, it is necessary to remember "Exergy Ecology and Democracy". by Goran Wall, a short essay, which evidences the strict relation that relates exergy disruption with environmental and social disruption. More recently it has verified that governmental emissions and impacts balances underestimate the effective GHG production by means of human processes. In fact, they often neglects the impacts of import/export related emissions. In addition they have analyzed the UN SDGs and the methods which are suggested for verifying the advances of the countries. This activity has evidenced that objective and coherent parameters are missing. Therefore, they suggest the introduction of exergy analysis as the most effective method for estimating the environmental degradation. Therefore, a novel fiscal model based on Exergy and availability disruption has been defined as the only possible way for overcoming the problems induced by the globalized markets. Organisations and conferences Environmental organisations can be global, regional, national or local; they can be government-run or private (NGO). Environmentalist activity exists in almost every country. Moreover, groups dedicated to community development and social justice also focus on environmental concerns. Some US environmental organisations, among them the Natural Resources Defense Council and the Environmental Defense Fund, specialise in bringing lawsuits (a tactic seen as particularly useful in that country). Other groups, such as the US-based National Wildlife Federation, Earth Day, National Cleanup Day, the Nature Conservancy, and The Wilderness Society, and global groups like the World Wide Fund for Nature and Friends of the Earth, disseminate information, participate in public hearings, lobby, stage demonstrations, and may purchase land for preservation. Statewide nonprofit organisations such as the Wyoming Outdoor Council often collaborate with these national organisations and employ similar strategies. Smaller groups, including Wildlife Conservation International, conduct research on endangered species and ecosystems. More radical organisations, such as Greenpeace, Earth First!, and the Earth Liberation Front, have more directly opposed actions they regard as environmentally harmful. While Greenpeace is devoted to nonviolent confrontation as a means of bearing witness to environmental wrongs and bringing issues into the public realm for debate, the underground Earth Liberation Front engages in the clandestine destruction of property, the release of caged or penned animals, and other criminal acts. Such tactics are regarded as unusual within the movement, however. On an international level, concern for the environment was the subject of a United Nations Conference on the Human Environment in Stockholm in 1972, attended by 114 nations. Out of this meeting developed the United Nations Environment Programme (UNEP) and the follow-up United Nations Conference on Environment and Development in 1992. Other international organisations in support of environmental policies development include the Commission for Environmental Cooperation (as part of NAFTA), the European Environment Agency (EEA), and the Intergovernmental Panel on Climate Change (IPCC).

Most recent deaths are in Brazil, where activists combat logging in the Amazon rainforest. 116 environmental activists were assassinated in 2014, and 185 in 2015. This represents more than two environmentalists assassinated every week in 2014 and three every week in 2015. More than 200 environmental activists were assassinated worldwide between 2016 and early 2018. A 2020 incident saw several rangers murdered in the Congo Rainforest by poaching squads. Occurrences like this are relatively common, and account for a large number of deaths. In popular culture The U.S. Forest Service created Smokey the Bear in 1944; he appeared in countless posters, radio and television programs, movies, press releases, and other guises to warn about forest fires. The comic strip Mark Trail, by environmentalist Ed Dodd, began in 1946; it still appears weekly in 175 newspapers. The children's animated show Captain Planet and the Planeteers, created by Ted Turner and Barbara Pyle in 1989 to inform children about environmental issues. The show aired for six seasons and 113 episodes, in 100 countries worldwide from 1990 to 1996. In 1974, Spokane, Washington, became one of the smallest cities ever to host a World's Fair. From Saturday, 4 May, to Sunday, 3 November 1974, Spokane hosted Expo 74, the first world's fair to focus on the environment. The theme of Expo 74 was "Celebrating Tomorrow's Fresh New Environment." (In 1982, Knoxville, Tennessee, was another small city to host a world's fair: Expo '82, with the theme, "Energy Turns the World.") FernGully: The Last Rainforest is an animated motion picture released in 1992, which focuses exclusively on the environment. The movie is based on a book under the same title by Diana Young. In 1998, a sequel, FernGully 2: The Magical Rescue, was introduced. Miss Earth is one of the Big Four international beauty pageants. (The other three are Miss Universe, Miss International, and Miss World.) Out of these four beauty pageants, Miss Earth is the only international beauty pageant that promotes "environmental awareness." The reigning titleholders dedicate their year to promote specific projects and often address issues concerning the environment and other global issues through school tours, tree planting activities, street campaigns, coastal clean ups, speaking engagements, shopping mall tours, media guesting, environmental fair, storytelling programs, eco-fashion shows, and other environmental activities. The Miss Earth winner is the spokesperson for the Miss Earth Foundation, the United Nations Environment Programme (UNEP) and other environmental organizations. The Miss Earth Foundation also works with the environmental departments and ministries of participating countries, various private sectors and corporations, as well as Greenpeace and the World Wildlife Foundation (WWF). Another area of environmentalism is to use art to raise awareness about misuse of the environment. One example is trashion, using trash to create clothes, jewelry, and other objects for the home. Marina DeBris is one trashion artist, who focuses on ocean and beach trash to design clothes and for fund raising, education. Criticism and alternative views When environmentalism first became popular during the early 20th century, the focus was wilderness protection and wildlife preservation. These goals reflected the interests of the movement's initial, primarily white middle and upper class supporters, including through viewing preservation and protection via a lens that failed to appreciate the centuries-long work of indigenous communities who had lived without ushering in the types of environmental devastation these settler colonial "environmentalists" now sought to mitigate. The actions of many mainstream environmental organizations still reflect these early principles. Numerous low-income minorities felt isolated or negatively impacted by the movement, exemplified by the Southwest Organizing Project's (SWOP) Letter to the Group of 10, a letter sent to major environmental organizations by several local environmental justice activists. The letter argued that the environmental movement was so concerned about cleaning up and preserving nature that it ignored the negative side-effects that doing so caused communities nearby, namely less job growth. In addition, the NIMBY movement has transferred locally unwanted land uses (LULUs) from middle-class neighborhoods to poor communities with large minority populations. Therefore, vulnerable communities with fewer political opportunities are more often exposed to hazardous waste and toxins. This has resulted in the PIBBY principle, or at least the PIMBY (Place-in-minorities'-backyard), as supported by the United Church of Christ's study in 1987. As a result, some minorities have viewed the environmental movement as elitist. Environmental elitism manifested itself in three different forms: Compositional – Environmentalists are from the middle and upper class. Ideological – The reforms benefit the movement's supporters but impose costs on nonparticipants. Impact – The reforms have "regressive social impacts". They disproportionately benefit environmentalists and harm underrepresented populations. Many environmentalists believe that human interference with 'nature' should be restricted or minimised as a matter of urgency (for the sake of life, or the planet, or just for the benefit of the human species), whereas environmental skeptics and anti-environmentalists do not believe that there is such a need. One can also regard oneself as an environmentalist and believe that human 'interference' with 'nature' should be increased. Nevertheless, there is a risk that the shift from emotional environmentalism into the technical management of natural resources and hazards could decrease the touch of humans with nature, leading to less concern with environment preservation. Increasingly, typical conservation rhetoric is being replaced with restoration approaches and larger landscape initiatives that seek to create more holistic impacts. In the 2000s, American author, film director, medical graduate and intellect Michael Crichton criticized environmentalism as being religiously motivated rather than grounded in empirical evidence, arguing that climate change was a natural part of Earth's history and had been occurring long before humans dominated the planet. Also claiming to argue from his minor education in anthropology, he stated that religion was a part of human social make-up and that if it was suppressed, it would simply re-emerge in another form. With the decline of Christianity and Church attendance in the Western world, environmentalism has become more popular according to him, which he termed as "the religion of urban atheists". Others seek a balance that involves both caring deeply for the environment while letting science guide human actions affecting it. Such an approach would avoid the emotionalism which, for example, anti-GMO activism has been criticized for, and protect the integrity of science. Planting trees, for another example, can be emotionally satisfying but should also involve being conscious of ecological concerns such as the effect on water cycles and the use of nonnative, potentially invasive species.

Natural environment

The natural environment or natural world encompasses all biotic and abiotic things occurring naturally, meaning in this case not artificial. The term is most often applied to Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity. The concept of the natural environment can be distinguished as components: Complete ecological units that function as natural systems without massive civilized human intervention, including all vegetation, microorganisms, soil, rocks, plateaus, mountains, the atmosphere and natural phenomena that occur within their boundaries and their nature. Universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water and climate, as well as energy, radiation, electric charge and magnetism, not originating from civilized human actions. In contrast to the natural environment is the built environment. Built environments are where humans have fundamentally transformed landscapes such as urban settings and agricultural land conversion, the natural environment is greatly changed into a simplified human environment. Even acts which seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment becomes an artificial one. Though many animals build things to provide a better environment for themselves, they are not human, hence beaver dams and the works of mound-building termites are thought of as natural. People cannot find absolutely natural environments on Earth, and naturalness usually varies in a continuum, from 100% natural in one extreme to 0% natural in the other. The massive environmental changes of humanity in the Anthropocene have fundamentally effected all natural environments including: climate change, biodiversity loss and pollution from plastic and other chemicals in the air and water. More precisely, we can consider the different aspects or components of an environment, and see that their degree of naturalness is not uniform. If, for instance, in an agricultural field, the mineralogic composition and the structure of its soil are similar to those of an undisturbed forest soil, but the structure is quite different. Composition Earth science generally recognizes four spheres, the lithosphere, the hydrosphere, the atmosphere and the biosphere as correspondent to rocks, water, air and life respectively. Some scientists include as part of the spheres of the Earth, the cryosphere (corresponding to ice) as a distinct portion of the hydrosphere, as well as the pedosphere (to soil) as an active and intermixed sphere. Earth science (also known as geoscience, the geographical sciences or the Earth Sciences), is an all-embracing term for the sciences related to the planet Earth. There are four major disciplines in earth sciences, namely geography, geology, geophysics and geodesy. These major disciplines use physics, chemistry, biology, chronology and mathematics to build a qualitative and quantitative understanding of the principal areas or spheres of Earth. Geological activity The Earth's crust or lithosphere, is the outermost solid surface of the planet and is chemically, physically and mechanically different from underlying mantle. It has been generated greatly by igneous processes in which magma cools and solidifies to form solid rock. Beneath the lithosphere lies the mantle which is heated by the decay of radioactive elements. The mantle though solid is in a state of rheic convection. This convection process causes the lithospheric plates to move, albeit slowly. The resulting process is known as plate tectonics. Volcanoes result primarily from the melting of subducted crust material or of rising mantle at mid-ocean ridges and mantle plumes. Water on Earth Most water is found in various kinds of natural body of water. Oceans An ocean is a major body of saline water and a component of the hydrosphere. Approximately 71% of the surface of the Earth (an area of some 362 million square kilometers) is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas. More than half of this area is over 3,000 meters (9,800 ft) deep. Average oceanic salinity is around 35 parts per thousand (ppt) (3.5%), and nearly all seawater has a salinity in the range of 30 to 38 ppt. Though generally recognized as several separate oceans, these waters comprise one global, interconnected body of salt water often referred to as the World Ocean or global ocean. The deep seabeds are more than half the Earth's surface, and are among the least-modified natural environments. The major oceanic divisions are defined in part by the continents, various archipelagos and other criteria, these divisions are : (in descending order of size) the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean and the Arctic Ocean. Rivers A river is a natural watercourse, usually freshwater, flowing toward an ocean, a lake, a sea or another river. A few rivers simply flow into the ground and dry up completely without reaching another body of water. The water in a river is usually in a channel, made up of a stream bed between banks. In larger rivers there is often also a wider floodplain shaped by waters over-topping the channel. Flood plains may be very wide in relation to the size of the river channel. Rivers are a part of the hydrological cycle. Water within a river is generally collected from precipitation through surface runoff, groundwater recharge, springs and the release of water stored in glaciers and snowpacks. Small rivers may also be called by several other names, including stream, creek and brook. Their current is confined within a bed and stream banks. Streams play an important corridor role in connecting fragmented habitats and thus in conserving biodiversity. The study of streams and waterways in general is known as surface hydrology. Lakes A lake (from Latin lacus) is a terrain feature, a body of water that is localized to the bottom of basin. A body of water is considered a lake when it is inland, is not part of an ocean and is larger and deeper than a pond. Natural lakes on Earth are generally found in mountainous areas, rift zones and areas with ongoing or recent glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world, there are many lakes because of chaotic drainage patterns left over from the last ice age. All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them. Ponds A pond is a body of standing water, either natural or human-made, that is usually smaller than a lake. A wide variety of human-made bodies of water are classified as ponds, including water gardens designed for aesthetic ornamentation, fish ponds designed for commercial fish breeding and solar ponds designed to store thermal energy. Ponds and lakes are distinguished from streams by their current speed. While currents in streams are easily observed, ponds and lakes possess thermally driven micro-currents and moderate wind-driven currents. These features distinguish a pond from many other aquatic terrain features, such as stream pools and tide pools. Human impact on water Humans impact the water in different ways such as modifying rivers (through dams and stream channelization), urbanization and deforestation. These impact lake levels, groundwater conditions, water pollution, thermal pollution, and marine pollution. Humans modify rivers by using direct channel manipulation. We build dams and reservoirs and manipulate the direction of the rivers and water path. Dams can usefully create reservoirs and hydroelectric power. However, reservoirs and dams may negatively impact the environment and wildlife. Dams stop fish migration and the movement of organisms downstream. Urbanization affects the environment because of deforestation and changing lake levels, groundwater conditions, etc. Deforestation and urbanization go hand in hand. Deforestation may cause flooding, declining stream flow and changes in riverside vegetation. The changing vegetation occurs because when trees cannot get adequate water they start to deteriorate, leading to a decreased food supply for the wildlife in an area. Atmosphere, climate and weather The atmosphere of the Earth serves as a key factor in sustaining the planetary ecosystem. The thin layer of gases that envelops the Earth is held in place by the planet's gravity. Dry air consists of 78% nitrogen, 21% oxygen, 1% argon, inert gases and carbon dioxide. The remaining gases are often referred to as trace gases. The atmosphere includes greenhouse gases such as carbon dioxide, methane, nitrous oxide and ozone. Filtered air includes trace amounts of many other chemical compounds. Air also contains a variable amount of water vapor and suspensions of water droplets and ice crystals seen as clouds. Many natural substances may be present in tiny amounts in an unfiltered air sample, including dust, pollen and spores, sea spray, volcanic ash and meteoroids. Various industrial pollutants also may be present, such as chlorine (elementary or in compounds), fluorine compounds, elemental mercury, and sulphur compounds such as sulphur dioxide (SO2). The ozone layer of the Earth's atmosphere plays an important role in reducing the amount of ultraviolet (UV) radiation that reaches the surface. As DNA is readily damaged by UV light, this serves to protect life at the surface. The atmosphere also retains heat during the night, thereby reducing the daily temperature extremes. Layers of the atmosphere Principal layers Earth's atmosphere can be divided into five main layers. These layers are mainly determined by whether temperature increases or decreases with altitude. From highest to lowest, these layers are: Exosphere: The outermost layer of Earth's atmosphere extends from the exobase upward, mainly composed of hydrogen and helium. Thermosphere: The top of the thermosphere is the bottom of the exosphere, called the exobase. Its height varies with solar activity and ranges from about . The International Space Station orbits in this layer, between . In another way, the thermosphere is Earth's second highest atmospheric layer, extending from approximately 260,000 feet at the mesopause to the thermopause at altitudes ranging from 1,600,000 to 3,300,000 feet. Mesosphere: The mesosphere extends from the stratopause to . It is the layer where most meteors burn up upon entering the atmosphere. Stratosphere: The stratosphere extends from the tropopause to about . The stratopause, which is the boundary between the stratosphere and mesosphere, typically is at . Troposphere: The troposphere begins at the surface and extends to between at the poles and at the equator, with some variation due to weather. The troposphere is mostly heated by transfer of energy from the surface, so on average the lowest part of the troposphere is warmest and temperature decreases with altitude. The tropopause is the boundary between the troposphere and stratosphere. Other layers Within the five principal layers determined by temperature there are several layers determined by other properties. The ozone layer is contained within the stratosphere. It is mainly located in the lower portion of the stratosphere from about , though the thickness varies seasonally and geographically. About 90% of the ozone in our atmosphere is contained in the stratosphere. The ionosphere: The part of the atmosphere that is ionized by solar radiation, stretches from and typically overlaps both the exosphere and the thermosphere. It forms the inner edge of the magnetosphere. The homosphere and heterosphere: The homosphere includes the troposphere, stratosphere and mesosphere. The upper part of the heterosphere is composed almost completely of hydrogen, the lightest element. The planetary boundary layer is the part of the troposphere that is nearest the Earth's surface and is directly affected by it, mainly through turbulent diffusion. Effects of global warming The dangers of global warming are being increasingly studied by a wide global consortium of scientists. These scientists are increasingly concerned about the potential long-term effects of global warming on our natural environment and on the planet. Of particular concern is how climate change and global warming caused by anthropogenic, or human-made releases of greenhouse gases, most notably carbon dioxide, can act interactively and have adverse effects upon the planet, its natural environment and humans' existence. It is clear the planet is warming, and warming rapidly. This is due to the greenhouse effect, which is caused by greenhouse gases, which trap heat inside the Earth's atmosphere because of their more complex molecular structure which allows them to vibrate and in turn trap heat and release it back towards the Earth. This warming is also responsible for the extinction of natural habitats, which in turn leads to a reduction in wildlife population. The most recent report from the Intergovernmental Panel on Climate Change (the group of the leading climate scientists in the world) concluded that the earth will warm anywhere from 2.7 to almost 11 degrees Fahrenheit (1.5 to 6 degrees Celsius) between 1990 and 2100. Efforts have been increasingly focused on the mitigation of greenhouse gases that are causing climatic changes, on developing adaptative strategies to global warming, to assist humans, other animal, and plant species, ecosystems, regions and nations in adjusting to the effects of global warming. Some examples of recent collaboration to address climate change and global warming include: The United Nations Framework Convention Treaty and convention on Climate Change, to stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system. The Kyoto Protocol, which is the protocol to the international Framework Convention on Climate Change treaty, again with the objective of reducing greenhouse gases in an effort to prevent anthropogenic climate change. The Western Climate Initiative, to identify, evaluate, and implement collective and cooperative ways to reduce greenhouse gases in the region, focusing on a market-based cap-and-trade system. A significantly profound challenge is to identify the natural environmental dynamics in contrast to environmental changes not within natural variances. A common solution is to adapt a static view neglecting natural variances to exist. Methodologically, this view could be defended when looking at processes which change slowly and short time series, while the problem arrives when fast processes turns essential in the object of the study. Climate Climate looks at the statistics of temperature, humidity, atmospheric pressure, wind, rainfall, atmospheric particle count and other meteorological elements in a given region over long periods of time. Weather, on the other hand, is the present condition of these same elements over periods up to two weeks. Climates can be classified according to the average and typical ranges of different variables, most commonly temperature and precipitation. The most commonly used classification scheme is the one originally developed by Wladimir Köppen. The Thornthwaite system, in use since 1948, uses evapotranspiration as well as temperature and precipitation information to study animal species diversity and the potential impacts of climate changes. Weather Weather is a set of all the phenomena occurring in a given atmospheric area at a given time. Most weather phenomena occur in the troposphere, just below the stratosphere. Weather refers, generally, to day-to-day temperature and precipitation activity, whereas climate is the term for the average atmospheric conditions over longer periods of time. When used without qualification, "weather" is understood to be the weather of Earth. Weather occurs due to density (temperature and moisture) differences between one place and another. These differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics. The strong temperature contrast between polar and tropical air gives rise to the jet stream. Weather systems in the mid-latitudes, such as extratropical cyclones, are caused by instabilities of the jet stream flow. Because the Earth's axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of the year. On the Earth's surface, temperatures usually range ±40 °C (100 °F to −40 °F) annually. Over thousands of years, changes in the Earth's orbit have affected the amount and distribution of solar energy received by the Earth and influenced long-term climate. Surface temperature differences in turn cause pressure differences. Higher altitudes are cooler than lower altitudes due to differences in compressional heating. Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. The atmosphere is a chaotic system, and small changes to one part of the system can grow to have large effects on the system as a whole. Human attempts to control the weather have occurred throughout human history, and there is evidence that civilized human activity such as agriculture and industry has inadvertently modified weather patterns. Life Evidence suggests that life on Earth has existed for about 3.7 billion years. All known life forms share fundamental molecular mechanisms, and based on these observations, theories on the origin of life attempt to find a mechanism explaining the formation of a primordial single cell organism from which all life originates. There are many different hypotheses regarding the path that might have been taken from simple organic molecules via pre-cellular life to protocells and metabolism. Although there is no universal agreement on the definition of life, scientists generally accept that the biological manifestation of life is characterized by organization, metabolism, growth, adaptation, response to stimuli and reproduction. Life may also be said to be simply the characteristic state of organisms. In biology, the science of living organisms, "life" is the condition which distinguishes active organisms from inorganic matter, including the capacity for growth, functional activity and the continual change preceding death. A diverse variety of living organisms (life forms) can be found in the biosphere on Earth, and properties common to these organisms—plants, animals, fungi, protists, archaea, and bacteria—are a carbon- and water-based cellular form with complex organization and heritable genetic information. Living organisms undergo metabolism, maintain homeostasis, possess a capacity to grow, respond to stimuli, reproduce and, through natural selection, adapt to their environment in successive generations. More complex living organisms can communicate through various means. Ecosystems An ecosystem (also called an environment) is a natural unit consisting of all plants, animals, and micro-organisms (biotic factors) in an area functioning together with all of the non-living physical (abiotic) factors of the environment. Central to the ecosystem concept is the idea that living organisms are continually engaged in a highly interrelated set of relationships with every other element constituting the environment in which they exist. Eugene Odum, one of the founders of the science of ecology, stated: "Any unit that includes all of the organisms (i.e.: the "community") in a given area interacting with the physical environment so that a flow of energy leads to clearly defined trophic structure, biotic diversity, and material cycles (i.e.: exchange of materials between living and nonliving parts) within the system is an ecosystem." The human ecosystem concept is then grounded in the deconstruction of the human/nature dichotomy, and the emergent premise that all species are ecologically integrated with each other, as well as with the abiotic constituents of their biotope. A more significant number or variety of species or biological diversity of an ecosystem may contribute to greater resilience of an ecosystem because there are more species present at a location to respond to change and thus "absorb" or reduce its effects. This reduces the effect before the ecosystem's structure changes to a different state. This is not universally the case and there is no proven relationship between the species diversity of an ecosystem and its ability to provide goods and services on a sustainable level. The term ecosystem can also pertain to human-made environments, such as human ecosystems and human-influenced ecosystems. It can describe any situation where there is relationship between living organisms and their environment. Fewer areas on the surface of the earth today exist free from human contact, although some genuine wilderness areas continue to exist without any forms of human intervention. Biogeochemical cycles Global biogeochemical cycles are critical to life, most notably those of water, oxygen, carbon, nitrogen and phosphorus. The nitrogen cycle is the transformation of nitrogen and nitrogen-containing compounds in nature. It is a cycle which includes gaseous components. The water cycle, is the continuous movement of water on, above, and below the surface of the Earth. Water can change states among liquid, vapour, and ice at various places in the water cycle. Although the balance of water on Earth remains fairly constant over time, individual water molecules can come and go. The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. The oxygen cycle is the movement of oxygen within and between its three main reservoirs: the atmosphere, the biosphere, and the lithosphere. The main driving factor of the oxygen cycle is photosynthesis, which is responsible for the modern Earth's atmospheric composition and life. The phosphorus cycle is the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. The atmosphere does not play a significant role in the movements of phosphorus, because phosphorus and phosphorus compounds are usually solids at the typical ranges of temperature and pressure found on Earth. Wilderness Wilderness is generally defined as a natural environment on Earth that has not been significantly modified by human activity. The WILD Foundation goes into more detail, defining wilderness as: "The most intact, undisturbed wild natural areas left on our planet – those last truly wild places that humans do not control and have not developed with roads, pipelines or other industrial infrastructure." Wilderness areas and protected parks are considered important for the survival of certain species, ecological studies, conservation, solitude, and recreation. Wilderness is deeply valued for cultural, spiritual, moral, and aesthetic reasons. Some nature writers believe wilderness areas are vital for the human spirit and creativity. The word, "wilderness", derives from the notion of wildness; in other words that which is not controllable by humans. The word etymology is from the Old English wildeornes, which in turn derives from wildeor meaning wild beast (wild + deor = beast, deer). From this point of view, it is the wildness of a place that makes it a wilderness. The mere presence or activity of people does not disqualify an area from being "wilderness". Many ecosystems that are, or have been, inhabited or influenced by activities of people may still be considered "wild". This way of looking at wilderness includes areas within which natural processes operate without very noticeable human interference. Wildlife includes all non-domesticated plants, animals and other organisms. Domesticating wild plant and animal species for human benefit has occurred many times all over the planet, and has a major impact on the environment, both positive and negative. Wildlife can be found in all ecosystems. Deserts, rain forests, plains, and other areas—including the most developed urban sites—all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by civilized human factors, most scientists agree that wildlife around the world is (now) impacted by human activities. Challenges It is the common understanding of natural environment that underlies environmentalism — a broad political, social and philosophical movement that advocates various actions and policies in the interest of protecting what nature remains in the natural environment, or restoring or expanding the role of nature in this environment. While true wilderness is increasingly rare, wild nature (e.g., unmanaged forests, uncultivated grasslands, wildlife, wildflowers) can be found in many locations previously inhabited by humans. Goals for the benefit of people and natural systems, commonly expressed by environmental scientists and environmentalists include: Elimination of pollution and toxicants in air, water, soil, buildings, manufactured goods, and food. Preservation of biodiversity and protection of endangered species. Conservation and sustainable use of resources such as water, land, air, energy, raw materials, and natural resources. Halting human-induced global warming, which represents pollution, a threat to biodiversity, and a threat to human populations. Shifting from fossil fuels to renewable energy in electricity, heating and cooling, and transportation, which addresses pollution, global warming, and sustainability. This may include public transportation and distributed generation, which have benefits for traffic congestion and electric reliability. Shifting from meat-intensive diets to largely plant-based diets in order to help mitigate biodiversity loss and climate change. Establishment of nature reserves for recreational purposes and ecosystem preservation. Sustainable and less polluting waste management including waste reduction (or even zero waste), reuse, recycling, composting, waste-to-energy, and anaerobic digestion of sewage sludge. Reducing profligate consumption and clamping down on illegal fishing and logging. Slowing and stabilisation of human population growth. Reducing the import of second hand electronic appliances from developed countries to developing countries. Criticism In some cultures the term environment is meaningless because there is no separation between people and what they view as the natural world, or their surroundings. Specifically in the United States and Arabian countries many native cultures do not recognize the "environment", or see themselves as environmentalists.

Environmental issues

Environmental issues are disruptions in the usual function of ecosystems. Further, these issues can be caused by humans (human impact on the environment) or they can be natural. These issues are considered serious when the ecosystem cannot recover in the present situation, and catastrophic if the ecosystem is projected to certainly collapse. Environmental protection is the practice of protecting the natural environment on the individual, organizational or governmental levels, for the benefit of both the environment and humans. Environmentalism is a social and environmental movement that addresses environmental issues through advocacy, legislation education, and activism. Environment destruction caused by humans is a global, ongoing problem. Water pollution also cause problems to marine life. Most scholars think that the project peak global world population of between 9-10 billion people, could live sustainably within the earth's ecosystems if human society worked to live sustainably within planetary boundaries. The bulk of environmental impacts are caused by excessive consumption of industrial goods by the world's wealthiest populations. The UN Environmental Program, in its "Making Peace With Nature" Report in 2021, found addressing key planetary crises, like pollution, climate change and biodiversity loss, was achievable if parties work to address the Sustainable Development Goals. Types Major current environmental issues may include climate change, pollution, environmental degradation, and resource depletion. The conservation movement lobbies for protection of endangered species and protection of any ecologically valuable natural areas, genetically modified foods and global warming. The UN system has adopted international frameworks for environmental issues in three key issues, which has been encoded as the "triple planetary crises": climate change, pollution, and biodiversity loss. Human impact Degradation Conflict Costs Action Justice The 2023 IPCC report highlighted the disproportionate effects of climate change on vulnerable populations. The report's findings make it clear that every increment of global warming exacerbates challenges such as extreme heatwaves, heavy rainfall, and other weather extremes, which in turn amplify risks for human health and ecosystems. With nearly half of the world's population residing in regions highly susceptible to climate change, the urgency for global actions that are both rapid and sustained is underscored. The importance of integrating diverse knowledge systems, including scientific, Indigenous, and local knowledge, into climate action is highlighted as a means to foster inclusive solutions that address the complexities of climate impacts across different communities. In addition, the report points out the critical gap in adaptation finance, noting that developing countries require significantly more resources to effectively adapt to climate challenges than what is currently available. This financial disparity raises questions about the global commitment to equitable climate action and underscores the need for a substantial increase in support and resources. The IPCC's analysis suggests that with adequate financial investment and international cooperation, it is possible to embark on a pathway towards resilience and sustainability that benefits all sections of society. Law Assessment Movement Organizations Environmental issues are addressed at a regional, national or international level by government organizations. The largest international agency, set up in 1972, is the United Nations Environment Programme. The International Union for Conservation of Nature brings together 83 states, 108 government agencies, 766 Non-governmental organizations and 81 international organizations and about 10,000 experts, scientists from countries around the world. International non-governmental organizations include Greenpeace, Friends of the Earth and World Wide Fund for Nature. Governments enact environmental policy and enforce environmental law and this is done to differing degrees around the world. Film and television There are an increasing number of films being produced on environmental issues, especially on climate change and global warming. Al Gore's 2006 film An Inconvenient Truth gained commercial success and a high media profile.

Ecosystem ecology

Ecosystem ecology is the integrated study of living (biotic) and non-living (abiotic) components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals, bedrock, soil, plants, and animals. Ecosystem ecology examines physical and biological structures and examines how these ecosystem characteristics interact with each other. Ultimately, this helps us understand how to maintain high quality water and economically viable commodity production. A major focus of ecosystem ecology is on functional processes, ecological mechanisms that maintain the structure and services produced by ecosystems. These include primary productivity (production of biomass), decomposition, and trophic interactions. Studies of ecosystem function have greatly improved human understanding of sustainable production of forage, fiber, fuel, and provision of water. Functional processes are mediated by regional-to-local level climate, disturbance, and management. Thus ecosystem ecology provides a powerful framework for identifying ecological mechanisms that interact with global environmental problems, especially global warming and degradation of surface water. This example demonstrates several important aspects of ecosystems: Ecosystem boundaries are often nebulous and may fluctuate in time Organisms within ecosystems are dependent on ecosystem level biological and physical processes Adjacent ecosystems closely interact and often are interdependent for maintenance of community structure and functional processes that maintain productivity and biodiversity These characteristics also introduce practical problems into natural resource management. Who will manage which ecosystem? Will timber cutting in the forest degrade recreational fishing in the stream? These questions are difficult for land managers to address while the boundary between ecosystems remains unclear; even though decisions in one ecosystem will affect the other. We need better understanding of the interactions and interdependencies of these ecosystems and the processes that maintain them before we can begin to address these questions. Ecosystem ecology is an inherently interdisciplinary field of study. An individual ecosystem is composed of populations of organisms, interacting within communities, and contributing to the cycling of nutrients and the flow of energy. The ecosystem is the principal unit of study in ecosystem ecology. Population, community, and physiological ecology provide many of the underlying biological mechanisms influencing ecosystems and the processes they maintain. Flowing of energy and cycling of matter at the ecosystem level are often examined in ecosystem ecology, but, as a whole, this science is defined more by subject matter than by scale. Ecosystem ecology approaches organisms and abiotic pools of energy and nutrients as an integrated system which distinguishes it from associated sciences such as biogeochemistry. Biogeochemistry and hydrology focus on several fundamental ecosystem processes such as biologically mediated chemical cycling of nutrients and physical-biological cycling of water. Ecosystem ecology forms the mechanistic basis for regional or global processes encompassed by landscape-to-regional hydrology, global biogeochemistry, and earth system science. History Ecosystem ecology is philosophically and historically rooted in terrestrial ecology. The ecosystem concept has evolved rapidly during the last 100 years with important ideas developed by Frederic Clements, a botanist who argued for specific definitions of ecosystems and that physiological processes were responsible for their development and persistence. Although most of Clements ecosystem definitions have been greatly revised, initially by Henry Gleason and Arthur Tansley, and later by contemporary ecologists, the idea that physiological processes are fundamental to ecosystem structure and function remains central to ecology. Later work by Eugene Odum and Howard T. Odum quantified flows of energy and matter at the ecosystem level, thus documenting the general ideas proposed by Clements and his contemporary Charles Elton. In this model, energy flows through the whole system were dependent on biotic and abiotic interactions of each individual component (species, inorganic pools of nutrients, etc.). Later work demonstrated that these interactions and flows applied to nutrient cycles, changed over the course of succession, and held powerful controls over ecosystem productivity. Transfers of energy and nutrients are innate to ecological systems regardless of whether they are aquatic or terrestrial. Thus, ecosystem ecology has emerged from important biological studies of plants, animals, terrestrial, aquatic, and marine ecosystems. Ecosystem services Ecosystem services are ecologically mediated functional processes essential to sustaining healthy human societies. Water provision and filtration, production of biomass in forestry, agriculture, and fisheries, and removal of greenhouse gases such as carbon dioxide (CO2) from the atmosphere are examples of ecosystem services essential to public health and economic opportunity. Nutrient cycling is a process fundamental to agricultural and forest production. However, like most ecosystem processes, nutrient cycling is not an ecosystem characteristic which can be “dialed” to the most desirable level. Maximizing production in degraded systems is an overly simplistic solution to the complex problems of hunger and economic security. For instance, intensive fertilizer use in the midwestern United States has resulted in degraded fisheries in the Gulf of Mexico. Regrettably, a “Green Revolution” of intensive chemical fertilization has been recommended for agriculture in developed and developing countries. These strategies risk alteration of ecosystem processes that may be difficult to restore, especially when applied at broad scales without adequate assessment of impacts. Ecosystem processes may take many years to recover from significant disturbance. For instance, large-scale forest clearance in the northeastern United States during the 18th and 19th centuries has altered soil texture, dominant vegetation, and nutrient cycling in ways that impact forest productivity in the present day. An appreciation of the importance of ecosystem function in maintenance of productivity, whether in agriculture or forestry, is needed in conjunction with plans for restoration of essential processes. Improved knowledge of ecosystem function will help to achieve long-term sustainability and stability in the poorest parts of the world. Operation Biomass productivity is one of the most apparent and economically important ecosystem functions. Biomass accumulation begins at the cellular level via photosynthesis. Photosynthesis requires water and consequently global patterns of annual biomass production are correlated with annual precipitation. Amounts of productivity are also dependent on the overall capacity of plants to capture sunlight which is directly correlated with plant leaf area and N content. Net primary productivity (NPP) is the primary measure of biomass accumulation within an ecosystem. Net primary productivity can be calculated by a simple formula where the total amount of productivity is adjusted for total productivity losses through maintenance of biological processes: NPP = GPP – Rproducer Where GPP is gross primary productivity and Rproducer is photosynthate (Carbon) lost via cellular respiration. NPP is difficult to measure but a new technique known as eddy co-variance has shed light on how natural ecosystems influence the atmosphere. Figure 4 shows seasonal and annual changes in CO2 concentration measured at Mauna Loa, Hawaii from 1987 to 1990. CO2 concentration steadily increased, but within-year variation has been greater than the annual increase since measurements began in 1957. These variations were thought to be due to seasonal uptake of CO2 during summer months. A newly developed technique for assessing ecosystem NPP has confirmed seasonal variation are driven by seasonal changes in CO2 uptake by vegetation. This has led many scientists and policy makers to speculate that ecosystems can be managed to ameliorate problems with global warming. This type of management may include reforesting or altering forest harvest schedules for many parts of the world. Decomposition and nutrient cycling Decomposition and nutrient cycling are fundamental to ecosystem biomass production. Most natural ecosystems are nitrogen (N) limited and biomass production is closely correlated with N turnover. Typically external input of nutrients is very low and efficient recycling of nutrients maintains productivity. Decomposition of plant litter accounts for the majority of nutrients recycled through ecosystems (Figure 3). Rates of plant litter decomposition are highly dependent on litter quality; high concentration of phenolic compounds, especially lignin, in plant litter has a retarding effect on litter decomposition. More complex C compounds are decomposed more slowly and may take many years to completely breakdown. Decomposition is typically described with exponential decay and has been related to the mineral concentrations, especially manganese, in the leaf litter. Globally, rates of decomposition are mediated by litter quality and climate. Ecosystems dominated by plants with low-lignin concentration often have rapid rates of decomposition and nutrient cycling (Chapin et al. 1982). Simple carbon (C) containing compounds are preferentially metabolized by decomposer microorganisms which results in rapid initial rates of decomposition, see Figure 5A, models that depend on constant rates of decay; so called “k” values, see Figure 5B. In addition to litter quality and climate, the activity of soil fauna is very important However, these models do not reflect simultaneous linear and non-linear decay processes which likely occur during decomposition. For instance, proteins, sugars and lipids decompose exponentially, but lignin decays at a more linear rate Thus, litter decay is inaccurately predicted by simplistic models. A simple alternative model presented in Figure 5C shows significantly more rapid decomposition that the standard model of figure 4B. Better understanding of decomposition models is an important research area of ecosystem ecology because this process is closely tied to nutrient supply and the overall capacity of ecosystems to sequester CO2 from the atmosphere. Trophic dynamics Trophic dynamics refers to process of energy and nutrient transfer between organisms. Trophic dynamics is an important part of the structure and function of ecosystems. Figure 3 shows energy transferred for an ecosystem at Silver Springs, Florida. Energy gained by primary producers (plants, P) is consumed by herbivores (H), which are consumed by carnivores (C), which are themselves consumed by “top- carnivores”(TC). One of the most obvious patterns in Figure 3 is that as one moves up to higher trophic levels (i.e. from plants to top-carnivores) the total amount of energy decreases. Plants exert a “bottom-up” control on the energy structure of ecosystems by determining the total amount of energy that enters the system. However, predators can also influence the structure of lower trophic levels from the top-down. These influences can dramatically shift dominant species in terrestrial and marine systems The interplay and relative strength of top-down vs. bottom-up controls on ecosystem structure and function is an important area of research in the greater field of ecology. Trophic dynamics can strongly influence rates of decomposition and nutrient cycling in time and in space. For example, herbivory can increase litter decomposition and nutrient cycling via direct changes in litter quality and altered dominant vegetation. Insect herbivory has been shown to increase rates of decomposition and nutrient turnover due to changes in litter quality and increased frass inputs. However, insect outbreak does not always increase nutrient cycling. Stadler showed that C rich honeydew produced during aphid outbreak can result in increased N immobilization by soil microbes thus slowing down nutrient cycling and potentially limiting biomass production. North atlantic marine ecosystems have been greatly altered by overfishing of cod. Cod stocks crashed in the 1990s which resulted in increases in their prey such as shrimp and snow crab Human intervention in ecosystems has resulted in dramatic changes to ecosystem structure and function. These changes are occurring rapidly and have unknown consequences for economic security and human well-being. Applications and importance Lessons from two Central American cities The biosphere has been greatly altered by the demands of human societies. Ecosystem ecology plays an important role in understanding and adapting to the most pressing current environmental problems. Restoration ecology and ecosystem management are closely associated with ecosystem ecology. Restoring highly degraded resources depends on integration of functional mechanisms of ecosystems. Without these functions intact, economic value of ecosystems is greatly reduced and potentially dangerous conditions may develop in the field. For example, areas within the mountainous western highlands of Guatemala are more susceptible to catastrophic landslides and crippling seasonal water shortages due to loss of forest resources. In contrast, cities such as Totonicapán that have preserved forests through strong social institutions have greater local economic stability and overall greater human well-being. This situation is striking considering that these areas are close to each other, the majority of inhabitants are of Mayan descent, and the topography and overall resources are similar. This is a case of two groups of people managing resources in fundamentally different ways. Ecosystem ecology provides the basic science needed to avoid degradation and to restore ecosystem processes that provide for basic human needs.

Human science

Human science (or human sciences in the plural) studies the philosophical, biological, social, justice, and cultural aspects of human life. Human science aims to expand the understanding of the human world through a broad interdisciplinary approach. It encompasses a wide range of fields - including history, philosophy, sociology, psychology, justice studies, evolutionary biology, biochemistry, neurosciences, folkloristics, and anthropology. It is the study and interpretation of the experiences, activities, constructs, and artifacts associated with human beings. The study of human sciences attempts to expand and enlighten the human being's knowledge of its existence, its interrelationship with other species and systems, and the development of artifacts to perpetuate the human expression and thought. It is the study of human phenomena. The study of the human experience is historical and current in nature. It requires the evaluation and interpretation of the historic human experience and the analysis of current human activity to gain an understanding of human phenomena and to project the outlines of human evolution. Human science is an objective, informed critique of human existence and how it relates to reality.Underlying human science is the relationship between various humanistic modes of inquiry within fields such as history, sociology, folkloristics, anthropology, and economics and advances in such things as genetics, evolutionary biology, and the social sciences for the purpose of understanding our lives in a rapidly changing world. Its use of an empirical methodology that encompasses psychological experience in contrasts with the purely positivistic approach typical of the natural sciences which exceeds all methods not based solely on sensory observations. Modern approaches in the human sciences integrate an understanding of human structure, function on and adaptation with a broader exploration of what it means to be human. The term is also used to distinguish not only the content of a field of study from that of the natural science, but also its methodology. Meaning of 'science' Ambiguity and confusion regarding the usage of the terms 'science', 'empirical science', and 'scientific method' have complicated the usage of the term 'human science' with respect to human activities. The term 'science' is derived from the Latin scientia, meaning 'knowledge'. 'Science' may be appropriately used to refer to any branch of knowledge or study dealing with a body of facts or truths systematically arranged to show the operation of general laws. However, according to positivists, the only authentic knowledge is scientific knowledge, which comes from the positive affirmation of theories through strict scientific methods the application of knowledge, or mathematics. As a result of the positivist influence, the term science is frequently employed as a synonym for empirical science. Empirical science is knowledge based on the scientific method, a systematic approach to verification of knowledge first developed for dealing with natural physical phenomena and emphasizing the importance of experience based on sensory observation. However, even with regard to the natural sciences, significant differences exist among scientists and philosophers of science with regard to what constitutes valid scientific method—for example, evolutionary biology, geology and astronomy, studying events that cannot be repeated, can use the method of historical narratives. More recently, usage of the term has been extended to the study of human social phenomena. Thus, natural and social sciences are commonly classified as science, whereas the study of classics, languages, literature, music, philosophy, history, religion, and the visual and performing arts are referred to as the humanities. Ambiguity with respect to the meaning of the term science is aggravated by the widespread use of the term formal science with reference to any one of several sciences that is predominantly concerned with abstract form that cannot be validated by physical experience through the senses, such as logic, mathematics, and the theoretical branches of computer science, information theory, and statistics. History The phrase 'human science' in English was used during the 17th-century scientific revolution, for example by Theophilus Gale, to draw a distinction between supernatural knowledge (divine science) and study by humans (human science). John Locke also uses 'human science' to mean knowledge produced by people, but without the distinction. By the 20th century, this latter meaning was used at the same time as 'sciences that make human beings the topic of research'. Early development The term "moral science" was used by David Hume (1711–1776) in his Enquiry concerning the Principles of Morals to refer to the systematic study of human nature and relationships. Hume wished to establish a "science of human nature" based upon empirical phenomena, and excluding all that does not arise from observation. Rejecting teleological, theological and metaphysical explanations, Hume sought to develop an essentially descriptive methodology; phenomena were to be precisely characterized. He emphasized the necessity of carefully explicating the cognitive content of ideas and vocabulary, relating these to their empirical roots and real-world significance. A variety of early thinkers in the humanistic sciences took up Hume's direction. Adam Smith, for example, conceived of economics as a moral science in the Humean sense. Later development Partly in reaction to the establishment of positivist philosophy and the latter's Comtean intrusions into traditionally humanistic areas such as sociology, non-positivistic researchers in the humanistic sciences began to carefully but emphatically distinguish the methodological approach appropriate to these areas of study, for which the unique and distinguishing characteristics of phenomena are in the forefront (e.g., for the biographer), from that appropriate to the natural sciences, for which the ability to link phenomena into generalized groups is foremost. In this sense, Johann Gustav Droysen contrasted the humanistic science's need to comprehend the phenomena under consideration with natural science's need to explain phenomena, while Windelband coined the terms idiographic for a descriptive study of the individual nature of phenomena, and nomothetic for sciences that aim to defthe generalizing laws. Wilhelm Dilthey brought nineteenth-century attempts to formulate a methodology appropriate to the humanistic sciences together with Hume's term "moral science", which he translated as Geisteswissenschaft - a term with no exact English equivalent. Dilthey attempted to articulate the entire range of the moral sciences in a comprehensive and systematic way. Meanwhile, his conception of “Geisteswissenschaften” encompasses also the abovementioned study of classics, languages, literature, music, philosophy, history, religion, and the visual and performing arts. He characterized the scientific nature of a study as depending upon: The conviction that perception gives access to reality The self-evident nature of logical reasoning The principle of sufficient reason But the specific nature of the Geisteswissenschaften is based on the "inner" experience (Erleben), the "comprehension" (Verstehen) of the meaning of expressions and "understanding" in terms of the relations of the part and the whole – in contrast to the Naturwissenschaften, the "explanation" of phenomena by hypothetical laws in the "natural sciences". Edmund Husserl, a student of Franz Brentano, articulated his phenomenological philosophy in a way that could be thought as a bthesis of Dilthey's attempt. Dilthey appreciated Husserl's Logische Untersuchungen (1900/1901, the first draft of Husserl's Phenomenology) as an “ep"epoch-making"istemological foundation of fors conception of Geisteswissenschaften. In recent years, 'human science' has been used to refer to "a philosophy and approach to science that seeks to understand human experience in deeply subjective, personal, historical, contextual, cross-cultural, political, and spiritual terms. Human science is the science of qualities rather than of quantities and closes the subject-object split in science. In particular, it addresses the ways in which self-reflection, art, music, poetry, drama, language and imagery reveal the human condition. By being interpretive, reflective, and appreciative, human science re-opens the conversation among science, art, and philosophy." Objective vs. subjective experiences Since Auguste Comte, the positivistic social sciences have sought to imitate the approach of the natural sciences by emphasizing the importance of objective external observations and searching for universal laws whose operation is predicated on external initial conditions that do not take into account differences in subjective human perception and attitude. Critics argue that subjective human experience and intention plays such a central role in determining human social behavior that an objective approach to the social sciences is too confining. Rejecting the positivist influence, they argue that the scientific method can rightly be applied to subjective, as well as objective, experience. The term subjective is used in this context to refer to inner psychological experience rather than outer sensory experience. It is not used in the sense of being prejudiced by personal motives or beliefs. Human science in universities Since 1878, the University of Cambridge has been home to the Moral Sciences Club, with strong ties to analytic philosophy. The Human Science degree is relatively young. It has been a degree subject at Oxford since 1969. At University College London, it was proposed in 1973 by Professor J. Z. Young and implemented two years later. His aim was to train general science graduates who would be scientifically literate, numerate and easily able to communicate across a wide range of disciplines, replacing the traditional classical training for higher-level government and management careers. Central topics include the evolution of humans, their behavior, molecular and population genetics, population growth and aging, ethnic and cultural diversity ,and human interaction with the environment, including conservation, disease ,and nutrition. The study of both biological and social disciplines, integrated within a framework of human diversity and sustainability, should enable the human scientist to develop professional competencies suited to address such multidimensional human problems. In the United Kingdom, Human Science is offered at the degree level at several institutions which include: University of Oxford University College London (as Human Sciences and as Human Sciences and Evolution) King's College London (as Anatomy, Developmental & Human Biology) University of Exeter Durham University (as Health and Human Sciences) Cardiff University (as Human and Social Sciences) In other countries: Osaka University Waseda University Tokiwa University Senshu University Aoyama Gakuin University (As College of Community Studies) Kobe University Kanagawa University Bunkyo University Sophia University Ghent University (in the narrow sense, as Moral sciences, "an integrated empirical and philosophical study of values, norms and world views") See also History of the Human Sciences (journal) Social science Humanism Humanities References Bibliography Flew, A.

Biocentrism (ethics)

Biocentrism (from Greek βίος bios, "life" and κέντρον kentron, "center"), in a political and ecological sense, as well as literally, is an ethical point of view that extends inherent value to all living things. It is an understanding of how the earth works, particularly as it relates to its biosphere or biodiversity. It stands in contrast to anthropocentrism, which centers on the value of humans. The related ecocentrism extends inherent value to the whole of nature. Advocates of biocentrism often promote the preservation of biodiversity, animal rights, and environmental protection. The term has also been employed by advocates of "left biocentrism", which combines deep ecology with an "anti-industrial and anti-capitalist" position (according to David Orton et al.). Definition In the simplest of terms as well as form, biocentrism is just the belief that all living organisms, regardless of species, complexity, or traits, individually possess equal value and the same exact right to live. Usually, the term biocentrism encompasses all environmental ethics that "extend the status of moral object from human beings to all living things in nature". Biocentric ethics calls for a rethinking of the relationship between humans and nature. It states that nature does not exist simply to be used or consumed by humans, but that humans are simply one species amongst many, and that because we are part of an ecosystem, any actions which negatively affect the living systems of which we are a part adversely affect us as well, whether or not we maintain a biocentric worldview. Biocentrists observe that all species have inherent value, and that humans are not "superior" to other species in a moral or ethical sense. The four main pillars of a biocentric outlook are: Humans and all other species are members of Earth's community. All species are part of a system of interdependence. All living organisms pursue their own "good" in their own ways. Human beings are not inherently superior to other living things. The most important of these four main pillars is likely the idea that human beings are not inherently superior to other living things. People have divergent views on many specific aspects of almost everything. Not all biocentrists even subscribe to the abstract concept of value, which is why heavy emphasis is placed on the fourth pillar. Relationship with animals and environment Biocentrism views individual species as parts of the living biosphere. It observes the consequences of reducing biodiversity on both small and large scales and points to the inherent value all species have to the environment. The environment is seen for what it is; the biosphere within which we live and depend on the maintaining of its diversity for our health. From these observations the ethical points are raised. History and development Biocentric ethics differs from classical and traditional ethical thinking. Rather than focusing on strict moral rules, as in Classical ethics, it focuses on attitudes and character. In contrast with traditional ethics, it is nonhierarchical and gives priority to the natural world rather than to humankind exclusively. Biocentric ethics includes Albert Schweitzer's ethics of "Reverence for Life", Peter Singer's ethics of Animal Liberation and Paul W. Taylor's ethics of biocentric egalitarianism. Albert Schweitzer's "reverence for life" principle was a precursor of modern biocentric ethics. In contrast with traditional ethics, the ethics of "reverence for life" denies any distinction between "high and low" or "valuable and less valuable" life forms, dismissing such categorization as arbitrary and subjective. Conventional ethics concerned itself exclusively with human beings—that is to say, morality applied only to interpersonal relationships—whereas Schweitzer's ethical philosophy introduced a "depth, energy, and function that differ[s] from the ethics that merely involved humans". "Reverence for life" was a "new ethics, because it is not only an extension of ethics, but also a transformation of the nature of ethics". Similarly, Peter Singer argues that non-human animals deserve the same equality of consideration that we extend to human beings. His argument is roughly as follows: Membership in the species Homo sapiens is the only criterion of moral importance that includes all humans and excludes all non-humans. Using membership in the species Homo sapiens as a criterion of moral importance is completely arbitrary. Of the remaining criteria we might consider, only sentience is a plausible criterion of moral importance. Using sentience as a criterion of moral importance entails that we extend the same basic moral consideration (i.e. "basic principle of equality") to other sentient creatures that we do to human beings. Therefore, we ought to extend to animals the same equality of consideration that we extend to human beings. Singer's work, while notable in the canon of environmental ethics, should not be considered as fully biocentric. Singer's ethics is extended from humans to nonhuman animals because the criterion for moral inclusion (sentience) is found in both humans and nonhuman animals, thus it would be arbitrary to deny it to nonhuman animals simply because they were not human. However, not all biological entities are sentient, consider: algae, plants and trees, fungi, lichens, mollusks, protozoa, for example. For an ethical theory to be biocentric, it must have a reason for extending ethical inclusion to the entire biosphere (as in Taylor and Schweitzer). The requirement for environmental ethics to move beyond sentience as criteria for inclusion in the moral realm is discussed in Tom Regan's 1981 paper "The Nature and Possibility of an Environmental Ethic". Biocentrism is most commonly associated with the work of Paul W. Taylor, especially his book Respect for Nature: A Theory of Environmental Ethics (1986). Taylor maintains that biocentrism is an "attitude of respect for nature", whereby one attempts to make an effort to live one's life in a way that respects the welfare and inherent worth of all living creatures. Taylor states that: Humans are members of a community of life along with all other species, and on equal terms. This community consists of a system of interdependence between all members, both physically, and in terms of relationships with other species. Every organism is a "teleological centre of life", that is, each organism has a purpose and a reason for being, which is inherently "good" or "valuable". Humans are not inherently superior to other species. Historian Donald Worster traces today's biocentric philosophies, which he sees as part of a recovery of a sense of kinship between man and nature, to the reaction by the British intelligencia of the Victorian era against the Christian ethic of dominion over nature. He has pointed to Charles Darwin as an important spokesman for the biocentric view in ecological thought and quotes from Darwin's Notebook on Transmutation of Species (1837): If we choose to let conjecture run wild, then animals, our fellow brethren in pain, diseases, death, suffering and famine—our slaves in the most laborious works, our companions in our amusement—they may partake of our origin in one common ancestor—we may be all netted together. In 1859, Charles Darwin published his book On the Origin of Species. This publication sparked the beginning of biocentrist views by introducing evolution and "its removal of humans from their supernatural origins and placement into the framework of natural laws". The work of Aldo Leopold has also been associated with biocentrism. The essay "The Land Ethic" in Leopold's book Sand County Almanac (1949) points out that although throughout history women and slaves have been considered property, all people have now been granted rights and freedoms. Leopold notes that today land is still considered property as people once were. He asserts that ethics should be extended to the land as "an evolutionary possibility and an ecological necessity". He argues that while people's instincts encourage them to compete with others, their ethics encourage them to co-operate with others. He suggests that "the land ethic simply enlarges the boundaries of the community to include soils, waters, plants, and animals, or collectively: the land". In a sense this attitude would encourage humans to co-operate with the land rather than compete with it. Outside of formal philosophical works biocentric thought is common among pre-colonial tribal peoples who knew no world other than the natural world. In law The paradigm of biocentrism and the values that it promotes are beginning to be used in law. In recent years (as of 2011), cities in Maine, Pennsylvania, New Hampshire and Virginia have adopted laws that protect the rights of nature. The purpose of these laws is to prevent the degradation of nature, especially by corporations who may want to exploit natural resources and land space, and to also use the environment as a dumping ground for toxic waste. The first country to include rights of nature in its constitution is Ecuador (see 2008 Constitution of Ecuador). Article 71 states that nature "has the right to integral respect for its existence and for the maintenance and regeneration of its life cycles, structure, functions and evolutionary processes". In religion Islam In Islam: In Islam, biocentric ethics stem from the belief that all of creation belongs to Allah (God), not humans, and to assume that non-human animals and plants exist merely to benefit humankind leads to environmental destruction and misuse. As all living organisms exist to praise God, human destruction of other living things prevents the earth's natural and subtle means of praising God. The Qur'an acknowledges that humans are not the only all-important creatures and emphasizes a respect for nature. Muhammad was once asked whether there would be a reward for those who show charity to nature and animals, to which he replied, "for charity shown to each creature with a wet heart [i.e. that is alive], there is a reward." Hinduism In Hinduism: Hinduism contains many elements of biocentrism. In Hinduism, humans have no special authority over other creatures, and all living things have souls ('atman'). Brahman (God) is the "efficient cause" and Prakrti (nature), is the "material cause" of the universe. However, Brahman and Prakrti are not considered truly divided: "They are one in [sic] the same, or perhaps better stated, they are the one in the many and the many in the one." However, while Hinduism does not give the same direct authority over nature that the Judeo-Christian-Islamic god grants, they are subject to a "higher and more authoritative responsibility for creation". The most important aspect of this is the doctrine of Ahimsa (non-violence). The Yājñavalkya Smṛti warns, "the wicked person who kills animals which are protected has to live in hell fire for the days equal to the number of hairs on the body of that animal". The essential aspect of this doctrine is the belief that the Supreme Being incarnates into the forms of various species. The Hindu belief in Saṃsāra (the cycle of life, death and rebirth) encompasses reincarnation into non-human forms. It is believed that one lives 8,400,000 lifetimes before one becomes a human. Each species is in this process of samsara until one attains moksha (liberation). Another doctrinal source for the equal treatment of all life is found in the Rigveda. The Rigveda states that trees and plants possess divine healing properties. It is still popularly believed that every tree has a Vriksa-devata (a tree deity). Trees are ritually worshiped through prayer, offerings, and the sacred thread ceremony. The Vriksa-devata worshiped as manifestations of the Divine. Tree planting is considered a religious duty. Jainism In Jainism: The Jaina tradition exists in tandem with Hinduism and shares many of its biocentric elements. Ahimsa (non-violence), the central teaching of Jainism, means more than not hurting other humans. It means intending not to cause physical, mental or spiritual harm to any part of nature. In the words of Mahavira: 'You are that which you wish to harm.' Compassion is a pillar of non-violence. Jainism encourages people to practice an attitude of compassion towards all life. The principle of interdependence is also very important in Jainism. This states that all of nature is bound together, and that "if one does not care for nature one does not care for oneself.". Another essential Jain teaching is self-restraint. Jainism discourages wasting the gifts of nature, and encourages its practitioners to reduce their needs as far as possible. Gandhi, a great proponent of Jainism, once stated "There is enough in this world for human needs, but not for human wants." Buddhism In Buddhism: The Buddha's teachings encourage people "to live simply, to cherish tranquility, to appreciate the natural cycle of life". Buddhism emphasizes that everything in the universe affects everything else. "Nature is an ecosystem in which trees affect climate, the soil, and the animals, just as the climate affects the trees, the soil, the animals and so on. The ocean, the sky, the air are all interrelated, and interdependent—water is life and air is life." Although this holistic approach is more ecocentric than biocentric, it is also biocentric, as it maintains that all living things are important and that humans are not above other creatures or nature. Buddhism teaches that "once we treat nature as our friend, to cherish it, then we can see the need to change from the attitude of dominating nature to an attitude of working with nature—we are an intrinsic part of all existence rather than seeing ourselves as in control of it." Christianity Within the Catholic tradition of Christian thought, Pope Benedict XVI noted that "the Church’s magisterium expresses grave misgivings about notions of the environment inspired by ecocentrism and biocentrism". This, he stated, was because "such notions eliminate the difference of identity and worth between the human person and other living things. In the name of a supposedly egalitarian vision of the "dignity" of all living creatures, such notions end up abolishing the distinctiveness and superior role of human beings." Criticism Biocentrism has faced criticism for a number of reasons. Some of this criticism grows out of the concern that biocentrism is an anti-human paradigm and that it will not hesitate to sacrifice human well-being for the greater good. Biocentrism has also been criticized for its individualism; emphasizing too much on the importance of individual life and neglecting the importance of collective groups, such as an ecosystem. A more complex form of criticism focuses on the contradictions of biocentrism. Opposed to anthropocentrism, which sees humans as having a higher status than other species, biocentrism puts humans on a par with the rest of nature, and not above it. In his essay A Critique of Anti-Anthropocentric Biocentrism Richard Watson suggests that if this is the case, then "Human ways—human culture—and human actions are as natural as the ways in which any other species of animals behaves". He goes on to suggest that if humans must change their behavior to refrain from disturbing and damaging the natural environment, then that results in setting humans apart from other species and assigning more power to them. This then takes us back to the basic beliefs of anthropocentrism. Watson also claims that the extinction of species is "Nature's way" and that if humans were to instigate their own self-destruction by exploiting the rest of nature, then so be it. Therefore, he suggests that the real reason humans should reduce their destructive behavior in relation to other species is not because we are equals but because the destruction of other species will also result in our own destruction. This view also brings us back to an anthropocentric perspective.

Applied science

Applied science is the application of the scientific method and scientific knowledge to attain practical goals. It includes a broad range of disciplines, such as engineering and medicine. Applied science is often contrasted with basic science, which is focused on advancing scientific theories and laws that explain and predict natural or other phenomena. There are applied natural sciences, as well as applied formal and social sciences. Applied science examples include genetic epidemiology which applies statistics and probability theory, and applied psychology, including criminology. Applied research Applied research is the use of empirical methods to collect data for practical purposes. It accesses and uses accumulated theories, knowledge, methods, and techniques for a specific state, business, or client-driven purpose. In contrast to engineering, applied research does not include analyses or optimization of business, economics, and costs. Applied research can be better understood in any area when contrasting it with basic or pure research. Basic geographical research strives to create new theories and methods that aid in explaining the processes that shape the spatial structure of physical or human environments. Instead, applied research utilizes existing geographical theories and methods to comprehend and address particular empirical issues. Applied research usually has specific commercial objectives related to products, procedures, or services. The comparison of pure research and applied research provides a basic framework and direction for businesses to follow. Applied research deals with solving practical problems and generally employs empirical methodologies. Because applied research resides in the messy real world, strict research protocols may need to be relaxed. For example, it may be impossible to use a random sample. Thus, transparency in the methodology is crucial. Implications for the interpretation of results brought about by relaxing an otherwise strict canon of methodology should also be considered. Moreover, this type of research method applies natural sciences to human conditions: Action research: aids firms in identifying workable solutions to issues influencing them. Evaluation research: researchers examine available data to assist clients in making wise judgments. Industrial research: create new goods/services that will satisfy the demands of a target market. (Industrial development would be scaling up production of the new goods/services for mass consumption to satisfy the economic demand of the customers while maximizing the ratio of the good/service output rate to resource input rate, the ratio of good/service revenue to material & energy costs, and the good/service quality. Industrial development would be considered engineering. Industrial development would fall outside the scope of applied research.) Since applied research has a provisional close-to-the-problem and close-to-the-data orientation, it may also use a more provisional conceptual framework, such as working hypotheses or pillar questions. The OECD's Frascati Manual describes applied research as one of the three forms of research, along with basic research & experimental development. Due to its practical focus, applied research information will be found in the literature associated with individual disciplines. Branches Applied research is a method of problem-solving and is also practical in areas of science, such as its presence in applied psychology. Applied psychology uses human behavior to grab information to locate a main focus in an area that can contribute to finding a resolution. More specifically, this study is applied in the area of criminal psychology. With the knowledge obtained from applied research, studies are conducted on criminals alongside their behavior to apprehend them. Moreover, the research extends to criminal investigations. Under this category, research methods demonstrate an understanding of the scientific method and social research designs used in criminological research. These reach more branches along the procedure towards the investigations, alongside laws, policy, and criminological theory. Engineering is the practice of using natural science, mathematics, and the engineering design process to solve technical problems, increase efficiency and productivity, and improve systems.The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. Engineering is often characterized as having four main branches: chemical engineering, civil engineering, electrical engineering, and mechanical engineering. Some scientific subfields used by engineers include thermodynamics, heat transfer, fluid mechanics, statics, dynamics, mechanics of materials, kinematics, electromagnetism, materials science, earth sciences, and engineering physics. Medical sciences, such as medical microbiology, pharmaceutical research, and clinical virology, are applied sciences that apply biology and chemistry to medicine. In education In Canada, the Netherlands, and other places, the Bachelor of Applied Science (BASc) is sometimes equivalent to the Bachelor of Engineering and is classified as a professional degree. This is based on the age of the school where applied science used to include boiler making, surveying, and engineering. There are also Bachelor of Applied Science degrees in Child Studies. The BASc tends to focus more on the application of the engineering sciences. In Australia and New Zealand, this degree is awarded in various fields of study and is considered a highly specialized professional degree. In the United Kingdom's educational system, Applied Science refers to a suite of "vocational" science qualifications that run alongside "traditional" General Certificate of Secondary Education or A-Level Sciences. Applied Science courses generally contain more coursework (also known as portfolio or internally assessed work) compared to their traditional counterparts. These are an evolution of the GNVQ qualifications offered up to 2005. These courses regularly come under scrutiny and are due for review following the Wolf Report 2011; however, their merits are argued elsewhere. In the United States, The College of William & Mary offers an undergraduate minor as well as Master of Science and Doctor of Philosophy degrees in "applied science". Courses and research cover varied fields, including neuroscience, optics, materials science and engineering, nondestructive testing, and nuclear magnetic resonance. University of Nebraska–Lincoln offers a Bachelor of Science in applied science, an online completion Bachelor of Science in applied science, and a Master of Applied Science. Coursework is centered on science, agriculture, and natural resources with a wide range of options, including ecology, food genetics, entrepreneurship, economics, policy, animal science, and plant science. In New York City, the Bloomberg administration awarded the consortium of Cornell-Technion $100 million in City capital to construct the universities' proposed Applied Sciences campus on Roosevelt Island.

Acclimatization

Acclimatization or acclimatisation (also called acclimation or acclimatation) is the process in which an individual organism adjusts to a change in its environment (such as a change in altitude, temperature, humidity, photoperiod, or pH), allowing it to maintain fitness across a range of environmental conditions. Acclimatization occurs in a short period of time (hours to weeks), and within the organism's lifetime (compared to adaptation, which is evolution, taking place over many generations). This may be a discrete occurrence (for example, when mountaineers acclimate to high altitude over hours or days) or may instead represent part of a periodic cycle, such as a mammal shedding heavy winter fur in favor of a lighter summer coat. Organisms can adjust their morphological, behavioral, physical, and/or biochemical traits in response to changes in their environment. While the capacity to acclimate to novel environments has been well documented in thousands of species, researchers still know very little about how and why organisms acclimate the way that they do. Names The nouns acclimatization and acclimation (and the corresponding verbs acclimatize and acclimate) are widely regarded as synonymous, both in general vocabulary and in medical vocabulary. The synonym acclimation is less commonly encountered, and fewer dictionaries enter it. Methods Biochemical In order to maintain performance across a range of environmental conditions, there are several strategies organisms use to acclimate. In response to changes in temperature, organisms can change the biochemistry of cell membranes making them more fluid in cold temperatures and less fluid in warm temperatures by increasing the number of membrane proteins. In response to certain stressors, some organisms express so-called heat shock proteins that act as molecular chaperones and reduce denaturation by guiding the folding and refolding of proteins. It has been shown that organisms which are acclimated to high or low temperatures display relatively high resting levels of heat shock proteins so that when they are exposed to even more extreme temperatures the proteins are readily available. Expression of heat shock proteins and regulation of membrane fluidity are just two of many biochemical methods organisms use to acclimate to novel environments. Morphological Organisms are able to change several characteristics relating to their morphology in order to maintain performance in novel environments. For example, birds often increase their organ size to increase their metabolism. This can take the form of an increase in the mass of nutritional organs or heat-producing organs, like the pectorals (with the latter being more consistent across species). The theory While the capacity for acclimatization has been documented in thousands of species, researchers still know very little about how and why organisms acclimate in the way that they do. Since researchers first began to study acclimation, the overwhelming hypothesis has been that all acclimation serves to enhance the performance of the organism. This idea has come to be known as the beneficial acclimation hypothesis. Despite such widespread support for the beneficial acclimation hypothesis, not all studies show that acclimation always serves to enhance performance (See beneficial acclimation hypothesis). One of the major objections to the beneficial acclimation hypothesis is that it assumes that there are no costs associated with acclimation. However, there are likely to be costs associated with acclimation. These include the cost of sensing the environmental conditions and regulating responses, producing structures required for plasticity (such as the energetic costs in expressing heat shock proteins), and genetic costs (such as linkage of plasticity-related genes with harmful genes). Given the shortcomings of the beneficial acclimation hypothesis, researchers are continuing to search for a theory that will be supported by empirical data. The degree to which organisms are able to acclimate is dictated by their phenotypic plasticity or the ability of an organism to change certain traits. Recent research in the study of acclimation capacity has focused more heavily on the evolution of phenotypic plasticity rather than acclimation responses. Scientists believe that when they understand more about how organisms evolved the capacity to acclimate, they will better understand acclimation. Examples Plants Many plants, such as maple trees, irises, and tomatoes, can survive freezing temperatures if the temperature gradually drops lower and lower each night over a period of days or weeks. The same drop might kill them if it occurred suddenly. Studies have shown that tomato plants that were acclimated to higher temperature over several days were more efficient at photosynthesis at relatively high temperatures than were plants that were not allowed to acclimate. In the orchid Phalaenopsis, phenylpropanoid enzymes are enhanced in the process of plant acclimatisation at different levels of photosynthetic photon flux. Animals Animals acclimatize in many ways. Sheep grow very thick wool in cold, damp climates. Fish are able to adjust only gradually to changes in water temperature and quality. Tropical fish sold at pet stores are often kept in acclimatization bags until this process is complete. Lowe & Vance (1995) were able to show that lizards acclimated to warm temperatures could maintain a higher running speed at warmer temperatures than lizards that were not acclimated to warm conditions. Fruit flies that develop at relatively cooler or warmer temperatures have increased cold or heat tolerance as adults, respectively (See Developmental plasticity). Humans The salt content of sweat and urine decreases as people acclimatize to hot conditions. Plasma volume, heart rate, and capillary activation are also affected. Acclimatization to high altitude continues for months or even years after initial ascent, and ultimately enables humans to survive in an environment that, without acclimatization, would kill them. Humans who migrate permanently to a higher altitude naturally acclimatize to their new environment by developing an increase in the number of red blood cells to increase the oxygen carrying capacity of the blood, in order to compensate for lower levels of oxygen intake.

Biomass

Biomass is a term used in several contexts: in the context of ecology it means living organisms, and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g., only from plants, from plants and algae, from plants and animals. The vast majority of biomass used for bioenergy does come from plants. Bioenergy is a type of renewable energy that the bioenergy industry claims has the potential to assist with climate change mitigation. Uses in different contexts Ecology Biomass (ecology), the mass of living biological organisms in a given area or ecosystem at a given time. This can be the biomass of particular species or the biomass of a particular community or habitat. Energy Biomass (energy), biomass used for energy production or in other words: biological mass used as a renewable energy source (usually produced through agriculture, forestry or aquaculture methods) Bioenergy, energy sources derived from biological material Solid fuel, forms of bioenergy that are solid Biofuel Energy crops Biotechnology Biomass is also used as a term for the mass of microorganisms that are used to produce industrial products like enzymes and medicines. Bioproducts Examples of emerging bioproducts or biobased products include biofuels, bioenergy, biochar, starch-based and cellulose-based ethanol, bio-based adhesives, biochemicals, bioplastics, etc. Biological wastewater treatment In biological wastewater treatment processes, such as the activated sludge process, the term "biomass" is used to denote the mass of bacteria and other microorganisms that break down pollutants in wastewater. The biomass forms part of sewage sludge. Others Biomass (satellite) - an Earth observation satellite Waste biomass fibre - potential source for cleaner production of textile References

Ecomodernism

Ecomodernism is an environmental philosophy which argues that technological development can protect nature and improve human wellbeing through eco-economic decoupling, i.e., by separating economic growth from environmental impacts. Description Ecomodernism embraces substituting natural ecological services with energy, technology, and synthetic solutions as long as they help reduce impact on environment. Among other things, ecomodernists embrace high-tech farming techniques to produce more food using less land and water, thus freeing up areas for conservation (precision agriculture, vertical farming, regenerative agriculture and genetically modified foods) and cellular agriculture (cultured meat) and alternative proteins, fish from aquaculture farms, desalination and water purification technologies, advanced waste recycling and circular economy, sustainable forestry and ecological restoration of natural habitats and biodiversity which includes a wide scope of projects including erosion control, reforestation, removal of non-native species and weeds, revegetation of degraded lands, daylighting streams, the reintroduction of native species (preferably native species that have local adaptation), and habitat and range improvement for targeted species, water conservation, Building Information Modeling in green building, green building and green infrastructure, smart grids, resource efficiency, urbanization, smart city, urban density and verticalization, adoption of electric vehicles and hydrogen vehicles, use of drone light shows, projection mapping and 3D holograms to provide a sustainable technological alternatives to fireworks, automation, carbon capture and storage and direct air capture, green nanotechnology (nanofilters for water purification, nanomaterials for air pollution control, nanocatalysts for more efficient chemical processes, nanostructured materials for improved solar cells, nanomaterials for enhancing battery performance, nanoparticles for soil and groundwater remediation and nanosensors for detecting pollutants), energy storage, alternative materials such as bioplastics and bio-based materials and high-tech materials such as graphene and carbon fibers, clean energy transition i.e. replacing low power-density energy sources (e.g. firewood in low-income countries, which leads to deforestation) with high power-density sources as long as their net impact on environment is lower (nuclear power plants, and advanced renewable energy sources), artificial intelligence for resource optimization (predictive maintenance in industrial settings to reduce waste, optimized routing for transportation to reduce fuel consumption, AI-driven climate modeling for better environmental predictions and supply chain optimization to reduce transportation emissions), climate engineering, synthetic fuels and biofuels, 3D printing, 3D food printing, digitalization, miniaturization, servitization of products and dematerialization. Key among the goals of an ecomodern environmental ethic is the use of technology to intensify human activity and make more room for wild nature. Debates that form the foundation of ecomodernism were born from disappointment in traditional organizations who denied energy sources such as nuclear power, thus leading to an increase of reliance of fossil gas and increase of emissions instead of reduction (e.g. Energiewende). Coming from evidence-based, scientific and pragmatic positions, ecomodernism engages in the debate on how to best protect natural environments, how to accelerate decarbonization to mitigate climate change, and how to accelerate the economic and social development of the world's poor. In these debates, ecomodernism distinguishes itself from other schools of thought, including ecological economics, degrowth, population reduction, laissez-faire economics, the "soft energy" path, and central planning. Ecomodernism draws on American pragmatism, political ecology, evolutionary economics, and modernism. Diversity of ideas and dissent are claimed values in order to avoid the intolerance born of extremism and dogmatism. Ecomodernist organisations have been established in many countries, including Germany, Finland, and Sweden. While the word 'ecomodernism' has only been used to describe modernist environmentalism since 2013, the term has a longer history in academic design writing and Ecomodernist ideas were developed within a number of earlier texts, including Martin Lewis's Green Delusions, Stewart Brand's Whole Earth Discipline and Emma Marris's Rambunctious Garden. In their 2015 manifesto, 18 self-professed ecomodernists—including scholars from the Breakthrough Institute, Harvard University, Jadavpur University, and the Long Now Foundation—sought to clarify the movement's vision: "we affirm one long-standing environmental ideal, that humanity must shrink its impacts on the environment to make more room for nature, while we reject another, that human societies must harmonize with nature to avoid economic and ecological collapse." An Ecomodernist Manifesto In April 2015, a group of 18 self-described ecomodernists collectively published An Ecomodernist Manifesto. Reception and criticism Some environmental journalists have praised An Ecomodernist Manifesto. At The New York Times, Eduardo Porter wrote approvingly of ecomodernism's alternative approach to sustainable development. In an article titled "Manifesto Calls for an End to 'People Are Bad' Environmentalism", Slate's Eric Holthaus wrote "It's inclusive, it's exciting, and it gives environmentalists something to fight for for a change." The science journal Nature editorialized the manifesto. Ecomodernism has been criticized for inadequately recognizing what Holly Jean Buck, Assistant Professor of Environment and Sustainability, says is the exploitative, violent and unequal dimensions of technological modernisation. Sociologist Eileen Crist, Associate Professor Emerita, observed that ecomodernism is founded on a western philosophy of humanism with no regard to "nonhuman freedoms". Of the Manifesto Crist says Human Geographer Rosemary-Claire Collard and co-authors assert that ecomodernism is incompatible with neoliberal capitalism, despite the philosophy's claims to the contrary. By contrast, in his book "Ecomodernism: Technology, Politics and the Climate Crisis" Jonathan Symons argues that ecomodernism belongs in the social democratic tradition, promoting a third way between laissez-faire and anti-capitalism, and calling for transformative state investments in technological transformation and human development. Likewise, in "A sympathetic diagnosis of the Ecomodernist Manifesto", Paul Robbins and Sarah A. Moore describe the similarities and points of departure between ecomodernism and political ecology. Another major strand of criticism towards ecomodernism comes from proponents of degrowth or the steady-state economy. Eighteen ecological economists published a long rejoinder titled "A Degrowth Response to an Ecomodernist Manifesto", writing "the ecomodernists provide neither a very inspiring blueprint for future development strategies nor much in the way of solutions to our environmental and energy woes." At the Breakthrough Institute's annual Dialogue in June 2015, several environmental scholars offered a critique of ecomodernism. Bruno Latour argued that the modernity celebrated in An Ecomodernist Manifesto is a myth. Jenny Price argued that the manifesto offered a simplistic view of "humanity" and "nature", which she said are "made invisible" by talking about them in such broad terms.

Environmental sociology

Environmental sociology is the study of interactions between societies and their natural environment. The field emphasizes the social factors that influence environmental resource management and cause environmental issues, the processes by which these environmental problems are socially constructed and define as social issues, and societal responses to these problems. Environmental sociology emerged as a subfield of sociology in the late 1970s in response to the emergence of the environmental movement in the 1960s. It represents a relatively new area of inquiry focusing on an extension of earlier sociology through inclusion of physical context as related to social factors. Definition Environmental sociology is typically defined as the sociological study of socio-environmental interactions, although this definition immediately presents the problem of integrating human cultures with the rest of the environment. Different aspects of human interaction with the natural environment are studied by environmental sociologists including population and demography, organizations and institutions, science and technology, health and illness, consumption and sustainability practices, culture and identity, and social inequality and environmental justice. Although the focus of the field is the relationship between society and environment in general, environmental sociologists typically place special emphasis on studying the social factors that cause environmental problems, the societal impacts of those problems, and efforts to solve the problems. In addition, considerable attention is paid to the social processes by which certain environmental conditions become socially defined as problems. Most research in environmental sociology examines contemporary societies. History Environmental sociology emerged as a coherent subfield of inquiry after the environmental movement of the 1960s and early 1970s. The works of William R. Catton, Jr. and Riley Dunlap, among others, challenged the constricted anthropocentrism of classical sociology. In the late 1970s, they called for a new holistic, or systems perspective, which lead to a marked shift in the field’s focus. Since the 1970s, general sociology has noticeably transformed to include environmental forces in social explanations. Environmental sociology has now solidified as a respected, interdisciplinary field of study in academia. Concepts Existential dualism The duality of the human condition rests with cultural uniqueness and evolutionary traits. From one perspective, humans are embedded in the ecosphere and co-evolved alongside other species. Humans share the same basic ecological dependencies as other inhabitants of nature. From the other perspectives, humans are distinguished from other species because of their innovative capacities, distinct cultures and varied institutions. Human creations have the power to independently manipulate, destroy, and transcend the limits of the natural environment. According to Buttel (2004), there are five major traditions in environmental sociology today: the treadmill of production and other eco-Marxisms, ecological modernization and other sociologies of environmental reform, cultural-environmental sociologies, neo-Malthusianisms, and the new ecological paradigm. In practice, this means five different theories of what to blame for environmental degradation, i.e., what to research or consider as important. These ideas are listed below in the order in which they were invented. Ideas that emerged later built on earlier ideas, and contradicted them. Neo-Malthusianism Works such as Hardin's "Tragedy of the Commons" (1969) reformulated Malthusian thought about abstract population increases causing famines into a model of individual selfishness at larger scales causing degradation of common pool resources such as the air, water, the oceans, or general environmental conditions. Hardin offered privatization of resources or government regulation as solutions to environmental degradation caused by tragedy of the commons conditions. Many other sociologists shared this view of solutions well into the 1970s (see Ophuls). There have been many critiques of this view particularly political scientist Elinor Ostrom, or economists Amartya Sen and Ester Boserup. Even though much of mainstream journalism considers Malthusianism the only view of environmentalism, most sociologists would disagree with Malthusianism since social organizational issues of environmental degradation are more demonstrated to cause environmental problems than abstract population or selfishness per se. For examples of this critique, Ostrom in her book Governing the Commons: The Evolution of Institutions for Collective Action (1990) argues that instead of self-interest always causing degradation, it can sometimes motivate people to take care of their common property resources. To do this they must change the basic organizational rules of resource use. Her research provides evidence for sustainable resource management systems, around common pool resources that have lasted for centuries in some areas of the world. Amartya Sen argues in his book Poverty and Famines: An Essay on Entitlement and Deprivation (1980) that population expansion fails to cause famines or degradation as Malthusians or Neo-Malthusians argue. Instead, in documented cases a lack of political entitlement to resources that exist in abundance, causes famines in some populations. He documents how famines can occur even in the midst of plenty or in the context of low populations. He argues that famines (and environmental degradation) would only occur in non-functioning democracies or unrepresentative states. Ester Boserup argues in her book The Conditions of Agricultural Growth: The Economics of Agrarian Change under Population Pressure (1965) from inductive, empirical case analysis that Malthus's more deductive conception of a presumed one-to-one relationship with agricultural scale and population is actually reversed. Instead of agricultural technology and scale determining and limiting population as Malthus attempted to argue, Boserup argued the world is full of cases of the direct opposite: that population changes and expands agricultural methods. Eco-Marxist scholar Allan Schnaiberg (below) argues against Malthusianism with the rationale that under larger capitalist economies, human degradation moved from localized, population-based degradation to organizationally caused degradation of capitalist political economies to blame. He gives the example of the organized degradation of rainforest areas which states and capitalists push people off the land before it is degraded by organizational means. Thus, many authors are critical of Malthusianism, from sociologists (Schnaiberg) to economists (Sen and Boserup), to political scientists (Ostrom), and all focus on how a country's social organization of its extraction can degrade the environment independent of abstract population. New Ecological Paradigm In the 1970s, the New Ecological Paradigm (NEP) conception critiqued the claimed lack of human-environmental focus in the classical sociologists and the sociological priorities their followers created. This was critiqued as the Human Exemptionalism Paradigm (HEP). The HEP viewpoint claims that human-environmental relationships were unimportant sociologically because humans are 'exempt' from environmental forces via cultural change. This view was shaped by the leading Western worldview of the time and the desire for sociology to establish itself as an independent discipline against the then popular racist-biological environmental determinism where environment was all. In this HEP view, human dominance was felt to be justified by the uniqueness of culture, argued to be more adaptable than biological traits. Furthermore, culture also has the capacity to accumulate and innovate, making it capable of solving all natural problems. Therefore, as humans were not conceived of as governed by natural conditions, they were felt to have complete control of their own destiny. Any potential limitation posed by the natural world was felt to be surpassed using human ingenuity. Research proceeded accordingly without environmental analysis. In the 1970s, sociological scholars Riley Dunlap and William R. Catton, Jr. began recognizing the limits of what would be termed the Human Excemptionalism Paradigm. Catton and Dunlap (1978) suggested a new perspective that took environmental variables into full account. They coined a new theoretical outlook for sociology, the New Ecological Paradigm, with assumptions contrary to HEP. The NEP recognizes the innovative capacity of humans, but says that humans are still ecologically interdependent as with other species. The NEP notes the power of social and cultural forces but does not profess social determinism. Instead, humans are impacted by the cause, effect, and feedback loops of ecosystems. The Earth has a finite level of natural resources and waste repositories. Thus, the biophysical environment can impose constraints on human activity. They discussed a few harbingers of this NEP in 'hybridized' theorizing about topics that were neither exclusively social nor environmental explanations of environmental conditions. It was additionally a critique of Malthusian views of the 1960s and 1970s. Dunlap and Catton's work immediately received a critique from Buttel who argued to the contrary that classical sociological foundations could be found for environmental sociology, particularly in Weber's work on ancient "agrarian civilizations" and Durkheim's view of the division of labor as built on a material premise of specialization/specialization in response to material scarcity. This environmental aspect of Durkheim has been discussed by Schnaiberg (1971) as well. Treadmill of Production Theory The Treadmill of Production is a theory coined and popularized by Schnaiberg as a way to answer for the increase in U.S. environmental degradation post World War II. At its simplest, this theory states that the more product or commodities are created, the more resources will be used, and the higher the impact will be. The treadmill is a metaphor of being caught in the cycle of continuous growth which never stops, demanding more resources and as a result causing more environmental damage. Eco-Marxism In the middle of the HEP/NEP debate Neo-Marxist ideas of conflict sociology were applied to environmental conflicts. Therefore, some sociologists wanted to stretch Marxist ideas of social conflict to analyze environmental social movements from the Marxist materialist framework instead of interpreting them as a cultural "New Social Movement", separate from material concerns. So "Eco-Marxism" was developed based on using Neo-Marxist Conflict theories concepts of the relative autonomy of the state and applying them to environmental conflict. Two people following this school were James O'Connor (The Fiscal Crisis of the State, 1971) and later Allan Schnaiberg. Later, a different trend developed in eco-Marxism via the attention brought to the importance of metabolic analysis in Marx's thought by John Bellamy Foster. Contrary to previous assumptions that classical theorists in sociology all had fallen within a Human Exemptionalist Paradigm, Foster argued that Marx's materialism lead him to theorize labor as the metabolic process between humanity and the rest of nature. In Promethean interpretations of Marx that Foster critiques, there was an assumption his analysis was very similar to the anthropocentric views critiqued by early environmental sociologists. Instead, Foster argued Marx himself was concerned about the Metabolic rift generated by capitalist society's social metabolism, particularly in industrial agriculture—Marx had identified an "irreparable rift in the interdependent process of social metabolism," created by capitalist agriculture that was destroying the productivity of the land and creating wastes in urban sites that failed to be reintegrated into the land and thus lead toward destruction of urban workers health simultaneously. Reviewing the contribution of this thread of eco-marxism to current environmental sociology, Pellow and Brehm conclude, "The metabolic rift is a productive development in the field because it connects current research to classical theory and links sociology with an interdisciplinary array of scientific literatures focused on ecosystem dynamics." Foster emphasized that his argument presupposed the "magisterial work" of Paul Burkett, who had developed a closely related "red-green" perspective rooted in a direct examination of Marx's value theory. Burkett and Foster proceeded to write a number of articles together on Marx's ecological conceptions, reflecting their shared perspective More recently, Jason W. Moore, inspired by Burkett's value-analytical approach to Marx's ecology and arguing that Foster's work did not in itself go far enough, has sought to integrate the notion of metabolic rift with world systems theory, incorporating Marxian value-related conceptions. For Moore, the modern world-system is a capitalist world-ecology, joining the accumulation of capital, the pursuit of power, and the production of nature in dialectical unity. Central to Moore's perspective is a philosophical re-reading of Marx's value theory, through which abstract social labor and abstract social nature are dialectically bound. Moore argues that the emergent law of value, from the sixteenth century, was evident in the extraordinary shift in the scale, scope, and speed of environmental change. What took premodern civilizations centuries to achieve—such as the deforestation of Europe in the medieval era—capitalism realized in mere decades. This world-historical rupture, argues Moore, can be explained through a law of value that regards labor productivity as the decisive metric of wealth and power in the modern world. From this standpoint, the genius of capitalist development has been to appropriate uncommodified natures—including uncommodified human natures—as a means of advancing labor productivity in the commodity system. Societal-environment dialectic In 1975, the highly influential work of Allan Schnaiberg transfigured environmental sociology, proposing a societal-environmental dialectic, though within the 'neo-Marxist' framework of the relative autonomy of the state as well. This conflictual concept has overwhelming political salience. First, the economic synthesis states that the desire for economic expansion will prevail over ecological concerns. Policy will decide to maximize immediate economic growth at the expense of environmental disruption. Secondly, the managed scarcity synthesis concludes that governments will attempt to control only the most dire of environmental problems to prevent health and economic disasters. This will give the appearance that governments act more environmentally consciously than they really do. Third, the ecological synthesis generates a hypothetical case where environmental degradation is so severe that political forces would respond with sustainable policies. The driving factor would be economic damage caused by environmental degradation. The economic engine would be based on renewable resources at this point. Production and consumption methods would adhere to sustainability regulations. These conflict-based syntheses have several potential outcomes. One is that the most powerful economic and political forces will preserve the status quo and bolster their dominance. Historically, this is the most common occurrence. Another potential outcome is for contending powerful parties to fall into a stalemate. Lastly, tumultuous social events may result that redistribute economic and political resources. In 1980,the highly influential work of Allan Schnaiberg entitled The Environment: From Surplus to Scarcity (1980) was a large contribution to this theme of a societal-environmental dialectic. Ecological modernization and reflexive modernization By the 1980s, a critique of eco-Marxism was in the offing, given empirical data from countries (mostly in Western Europe like the Netherlands, Western Germany and somewhat the United Kingdom) that were attempting to wed environmental protection with economic growth instead of seeing them as separate. This was done through both state and capital restructuring. Major proponents of this school of research are Arthur P.J. Mol and Gert Spaargaren. Popular examples of ecological modernization would be "cradle to cradle" production cycles, industrial ecology, large-scale organic agriculture, biomimicry, permaculture, agroecology and certain strands of sustainable development—all implying that economic growth is possible if that growth is well organized with the environment in mind. Reflexive modernization The many volumes of the German sociologist Ulrich Beck first argued from the late 1980s that our risk society is potentially being transformed by the environmental social movements of the world into structural change without rejecting the benefits of modernization and industrialization. This is leading to a form of 'reflexive modernization' with a world of reduced risk and better modernization process in economics, politics, and scientific practices as they are made less beholden to a cycle of protecting risk from correction (which he calls our state's organized irresponsibility)—politics creates ecodisasters, then claims responsibility in an accident, yet nothing remains corrected because it challenges the very structure of the operation of the economy and the private dominance of development, for example. Beck's idea of a reflexive modernization looks forward to how our ecological and social crises in the late 20th century are leading toward transformations of the whole political and economic system's institutions, making them more "rational" with ecology in mind. Neo-Liberalism Neo-liberalism includes deregulation, free market capitalism, and aims at reducing government spending. These Neo-liberal policies greatly affect environmental sociology. Since Neo-liberalism includes deregulation and essentially less government involvement, this leads to the commodification and privatization of unowned, state-owned, or common property resources. Diana Liverman and Silvina Vilas mentions that this results in payments for environmental services; deregulation and cuts in public expenditure for environmental management; the opening up of trade and investment; and transfer of environmental management to local or nongovernmental institutions. The privatization of these resources have impacts on society, the economy, and to the environment. An example that has greatly affected society is the privatization of water. Social construction of the environment Additionally in the 1980s, with the rise of postmodernism in the western academy and the appreciation of discourse as a form of power, some sociologists turned to analyzing environmental claims as a form of social construction more than a 'material' requirement. Proponents of this school include John A. Hannigan, particularly in Environmental Sociology: A Social Constructionist Perspective (1995). Hannigan argues for a 'soft constructionism' (environmental problems are materially real though they require social construction to be noticed) over a 'hard constructionism' (the claim that environmental problems are entirely social constructs). Although there was sometimes acrimonious debate between the constructivist and realist "camps" within environmental sociology in the 1990s, the two sides have found considerable common ground as both increasingly accept that while most environmental problems have a material reality they nonetheless become known only via human processes such as scientific knowledge, activists' efforts, and media attention. In other words, most environmental problems have a real ontological status despite our knowledge/awareness of them stemming from social processes, processes by which various conditions are constructed as problems by scientists, activists, media and other social actors. Correspondingly, environmental problems must all be understood via social processes, despite any material basis they may have external to humans. This interactiveness is now broadly accepted, but many aspects of the debate continue in contemporary research in the field. Events Modern environmentalism United States The 1960s built strong cultural momentum for environmental causes, giving birth to the modern environmental movement and large questioning in sociologists interested in analyzing the movement. Widespread green consciousness moved vertically within society, resulting in a series of policy changes across many states in the U.S. and Europe in the 1970s. In the United States, this period was known as the "Environmental Decade" with the creation of the United States Environmental Protection Agency and passing of the Endangered Species Act, Clean Water Act, and amendments to the Clean Air Act. Earth Day of 1970, celebrated by millions of participants, represented the modern age of environmental thought. The environmental movement continued with incidences such as Love Canal. Historical studies While the current mode of thought expressed in environmental sociology was not prevalent until the 1970s, its application is now used in analysis of ancient peoples. Societies including Easter Island, the Anaszi, and the Mayans were argued to have ended abruptly, largely due to poor environmental management. This has been challenged in later work however as the exclusive cause (biologically trained Jared Diamond's Collapse (2005); or more modern work on Easter Island). The collapse of the Mayans sent a historic message that even advanced cultures are vulnerable to ecological suicide—though Diamond argues now it was less of a suicide than an environmental climate change that led to a lack of an ability to adapt—and a lack of elite willingness to adapt even when faced with the signs much earlier of nearing ecological problems. At the same time, societal successes for Diamond included New Guinea and Tikopia island whose inhabitants have lived sustainably for 46,000 years. John Dryzek et al. argue in Green States and Social Movements: Environmentalism in the United States, United Kingdom, Germany, and Norway (2003) that there may be a common global green environmental social movement, though its specific outcomes are nationalist, falling into four 'ideal types' of interaction between environmental movements and state power. They use as their case studies environmental social movements and state interaction from Norway, the United Kingdom, the United States, and Germany. They analyze the past 30 years of environmentalism and the different outcomes that the green movement has taken in different state contexts and cultures. Recently and roughly in temporal order below, much longer-term comparative historical studies of environmental degradation are found by sociologists. There are two general trends: many employ world systems theory—analyzing environmental issues over long periods of time and space; and others employ comparative historical methods. Some utilize both methods simultaneously, sometimes without reference to world systems theory (like Whitaker, see below). Stephen G. Bunker (d. 2005) and Paul S. Ciccantell collaborated on two books from a world-systems theory view, following commodity chains through history of the modern world system, charting the changing importance of space, time, and scale of extraction and how these variables influenced the shape and location of the main nodes of the world economy over the past 500 years. Their view of the world was grounded in extraction economies and the politics of different states that seek to dominate the world's resources and each other through gaining hegemonic control of major resources or restructuring global flows in them to benefit their locations. The three volume work of environmental world-systems theory by Sing C. Chew analyzed how "Nature and Culture" interact over long periods of time, starting with World Ecological Degradation (2001) In later books, Chew argued that there were three "Dark Ages" in world environmental history characterized by periods of state collapse and reorientation in the world economy associated with more localist frameworks of community, economy, and identity coming to dominate the nature/culture relationships after state-facilitated environmental destruction delegitimized other forms. Thus recreated communities were founded in these so-called 'Dark Ages,' novel religions were popularized, and perhaps most importantly to him the environment had several centuries to recover from previous destruction. Chew argues that modern green politics and bioregionalism is the start of a similar movement of the present day potentially leading to wholesale system transformation. Therefore, we may be on the edge of yet another global "dark age" which is bright instead of dark on many levels since he argues for human community returning with environmental healing as empires collapse. More case oriented studies were conducted by historical environmental sociologist Mark D. Whitaker analyzing China, Japan, and Europe over 2,500 years in his book Ecological Revolution (2009). He argued that instead of environmental movements being "New Social Movements" peculiar to current societies, environmental movements are very old—being expressed via religious movements in the past (or in the present like in ecotheology) that begin to focus on material concerns of health, local ecology, and economic protest against state policy and its extractions. He argues past or present is very similar: that we have participated with a tragic common civilizational process of environmental degradation, economic consolidation, and lack of political representation for many millennia which has predictable outcomes. He argues that a form of bioregionalism, the bioregional state, is required to deal with political corruption in present or in past societies connected to environmental degradation. After looking at the world history of environmental degradation from very different methods, both sociologists Sing Chew and Mark D. Whitaker came to similar conclusions and are proponents of (different forms of) bioregionalism.

Sustainable design

Environmentally sustainable design (also called environmentally conscious design, eco-design, etc.) is the philosophy of designing physical objects, the built environment, and services to comply with the principles of ecological sustainability and also aimed at improving the health and comfort of occupants in a building. Sustainable design seeks to reduce negative impacts on the environment, the health and well-being of building occupants, thereby improving building performance. The basic objectives of sustainability are to reduce the consumption of non-renewable resources, minimize waste, and create healthy, productive environments. Theory The sustainable design intends to "eliminate negative environmental impact through skillful sensitive design". Manifestations of sustainable design require renewable resources and innovation to impact the environment minimally, and connect people with the natural environment. "Human beings don't have a pollution problem; they have a design problem. If humans were to devise products, tools, furniture, homes, factories, and cities more intelligently from the start, they wouldn't even need to think in terms of waste, contamination, or scarcity. Good design would allow for abundance, endless reuse, and pleasure." - The Upcycle by authors Michael Braungart and William McDonough, 2013. Design-related decisions are happening everywhere daily, impacting "sustainable development" or provisioning for the needs of future generations of life on earth. Sustainability and design are intimately linked. Quite simply, our future is designed. The term "design" is here used to refer to practices applied to the making of products, services, as well as business and innovation strategies — all of which inform sustainability. Sustainability can be thought of as the property of continuance; that is, what is sustainable can be continued. Conceptual problems Diminishing returns The principle that all directions of progress run out, ending with diminishing returns, is evident in the typical 'S' curve of the technology life cycle and in the useful life of any system as discussed in industrial ecology and life cycle assessment. Diminishing returns are the result of reaching natural limits. Common business management practice is to read diminishing returns in any direction of effort as an indication of diminishing opportunity, the potential for accelerating decline, and a signal to seek new opportunities elsewhere. (see also: law of diminishing returns, marginal utility, and Jevons paradox.) Unsustainable investment A problem arises when the limits of a resource are hard to see, so increasing investment in response to diminishing returns may seem profitable as in the Tragedy of the Commons, but may lead to a collapse. This problem of increasing investment in diminishing resources has also been studied as a cause of civilization collapse by Joseph Tainter among others. This natural error in investment policy contributed to the collapse of both the Roman and Mayan, among others. Relieving over-stressed resources requires reducing pressure on them, not continually increasing it whether more efficiently or not. Negative Effects of Waste The designer is responsible for choices that place a demand on natural resources, produce waste, and potentially cause irreversible ecosystem damage. About 80 million tonnes of waste in total are generated in the U.K. alone, for example, each year. And concerning only household waste, between 1991–92 and 2007–08, each person in England generated an average of 1.35 pounds of waste per day. Experience has now shown that there is no completely safe method of waste disposal. All forms of disposal have negative effects on the environment, public innovation, and local economies. Landfills have contaminated drinking water. Garbage burned in incinerators has poisoned air, soil, and water. The majority of water treatment systems change the local ecology. Attempts to control or manage wastes after they are produced fail to eliminate environmental impacts. The toxic components of household products pose serious health risks and aggravate the trash problem. In the U.S., about seven pounds in every ton of household garbage contains toxic materials, such as heavy metals like nickel, lead, cadmium, and mercury from batteries, and organic compounds found in pesticides and consumer products, such as air freshener sprays, nail polish, cleaners, and other products. When burned or buried, toxic materials also pose a serious threat to public health and the environment. The only way to avoid environmental harm from waste is to prevent its generation. Pollution prevention means changing the way activities are conducted and eliminating the source of the problem. It does not mean doing without, but doing differently. For example, preventing waste pollution from litter caused by disposable beverage containers does not mean doing without beverages; it just means using refillable bottles. Industrial designer Victor Papanek has stated that when we design and plan things to be discarded, we exercise insufficient care in design. Waste prevention strategies In planning for facilities, a comprehensive design strategy is needed for preventing the generation of solid waste. A good garbage prevention strategy would require that everything brought into a facility is recycled for reuse or recycled back into the environment through biodegradation. This would mean a greater reliance on natural materials or products that are compatible with the environment. Any resource-related development is going to have two basic sources of solid waste — materials purchased and used by the facility and those brought into the facility by visitors. The following waste prevention strategies apply to both, although different approaches will be needed for implementation. use products that minimize waste and are nontoxic compost or anaerobically digest biodegradable wastes reuse materials onsite or collect suitable materials for offsite recycling consuming fewer resources means creating less waste, therefore it reduces the impact on the environment. Climate change Perhaps the most obvious and overshadowing driver of environmentally conscious sustainable design can be attributed to global warming and climate change. The sense of urgency that now prevails for humanity to take action against climate change has increased manifold in the past thirty years. Climate change can be attributed to several faults, and improper design that doesn't take into consideration the environment is one of them. While several steps in the field of sustainability have begun, most products, industries, and buildings still consume a lot of energy and create a lot of pollution. Loss of Biodiversity Unsustainable design, or simply design, also affects the biodiversity of a region. Improper design of transport highways forces thousands of animals to move further into forest boundaries. Poorly designed hydrothermal dams affect the mating cycle and indirectly, the numbers of local fish. Sustainable design principles While the practical application varies among disciplines, some common principles are as follows: Low-impact materials: choose non-toxic, sustainably produced, or recycled materials that require little energy to process Energy efficiency: use manufacturing processes and produce products that require less energy Emotionally durable design: reducing consumption and waste of resources by increasing the durability of relationships between people and products, through design Design for reuse and recycling: "Products, processes, and systems should be designed for performance in a commercial 'afterlife'." Targeted durability, not immortality, should be a design goal. Material diversity in multicomponent products should be minimized to promote disassembly and value retention. Design impact measures for total carbon footprint and life-cycle assessment for any resource used are increasingly required and available.^ Many are complex, but some give quick and accurate whole-earth estimates of impacts. One measure estimates any spending as consuming an average economic share of global energy use of per dollar and producing at the average rate of 0.57 kg of per dollar (1995 dollars US) from DOE figures. Sustainable design standards and project design guides are also increasingly available and are vigorously being developed by a wide array of private organizations and individuals. There is also a large body of new methods emerging from the rapid development of what has become known as 'sustainability science' promoted by a wide variety of educational and governmental institutions. Biomimicry: "redesigning industrial systems on biological lines ... enabling the constant reuse of materials in continuous closed cycles..." Service substitution: shifting the mode of consumption from personal ownership of products to provision of services that provide similar functions, e.g., from a private automobile to a carsharing service. Such a system promotes minimal resource use per unit of consumption (e.g., per trip driven). Renewable resource: materials should come from nearby (local or bioregional), sustainably managed renewable sources that can be composted when their usefulness has been exhausted. Bill of Rights for the Planet A model of the new design principles necessary for sustainability is exemplified by the "Bill of Rights for the Planet" or "Hannover Principles" - developed by William McDonough Architects for EXPO 2000 that was held in Hannover, Germany. The Bill of Rights: Insist on the right of humanity and nature to co-exist in healthy, supportive, diverse, and sustainable conditions. Recognize Interdependence. The elements of human design interact with and depend on the natural world, with broad and diverse implications at every scale. Expand design considerations to recognize even distant effects. Respect relationships between spirit and matter. Consider all aspects of human settlement including community, dwelling, industry, and trade in terms of existing and evolving connections between spiritual and material consciousness. Accept responsibility for the consequences of design decisions upon human well-being, the viability of natural systems, and their right to co-exist. Create safe objects of long-term value. Do not burden future generations with requirements for maintenance or vigilant administration of potential danger due to the careless creation of products, processes, or standards. Eliminate the concept of waste. Evaluate and optimize the full life-cycle of products and processes, to approach the state of natural systems in which there is no waste. Rely on natural energy flows. Human designs should, like the living world, derive their creative forces from perpetual solar income. Incorporating this energy efficiently and safely for responsible use. Understand the limitations of design. No human creation lasts forever and design does not solve all problems. Those who create and plan should practice humility in the face of nature. Treat nature as a model and mentor, not an inconvenience to be evaded or controlled. Seek constant improvement by the sharing of knowledge. Encourage direct and open communication between colleagues, patrons, manufacturers, and users to link long-term sustainable considerations with ethical responsibility, and re-establish the integral relationship between natural processes and human activity. These principles were adopted by the World Congress of the International Union of Architects (UIA) in June 1993 at the American Institute of Architects (AIA) Expo 93 in Chicago. Further, the AIA and UIA signed a "Declaration of Interdependence for a Sustainable Future." In summary, the declaration states that today's society is degrading its environment and that the AIA, UIA, and their members are committed to: Placing environmental and social sustainability at the core of practices and professional responsibilities Developing and continually improving practices, procedures, products, services, and standards for sustainable design Educating the building industry, clients, and the general public about the importance of sustainable design Working to change policies, regulations, and standards in government and business so that sustainable design will become the fully supported standard practice Bringing the existing built environment up to sustainable design standards. In addition, the Interprofessional Council on Environmental Design (ICED), a coalition of architectural, landscape architectural, and engineering organizations developed a vision statement in an attempt to foster a team approach to sustainable design. ICED states: The ethics, education, and practices of our professions will be directed to shape a sustainable future. . . . To achieve this vision we will join . . . as a multidisciplinary partnership." These activities are an indication that the concept of sustainable design is being supported on a global and interprofessional scale and that the ultimate goal is to become more environmentally responsive. The world needs facilities that are more energy-efficient and that promote conservation and recycling of natural and economic resources. Economically and socially sustainable design Environmentally sustainable design is most beneficial when it works hand-in-hand with the other two counterparts of sustainable design – the economic and socially sustainable designs. These three terms are often coined under the title "triple bottom line." In addition to financial terms, value can also be measured in relation to natural capital (the biosphere and earth's resources), social capital (the norms and networks that enable collective action), and human capital (the sum total of knowledge, experience, intellectual property, and labor available to society). In some countries the term sustainable design is known as ecodesign, green design or environmental design. Victor Papanek, embraced social design and social quality and ecological quality, but did not explicitly combine these areas of design concern in one term. Sustainable design and design for sustainability are more common terms, including the triple bottom line (people, planet and profit). Advocates like Ecothis.EU campaign urge all three considerations be taken into account when designing a circular economy. Aspects of environmentally sustainable design Emotionally durable design According to Jonathan Chapman of Carnegie Mellon University, emotionally durable design reduces the consumption and waste of natural resources by increasing the resilience of relationships established between consumers and products." Essentially, product replacement is delayed by strong emotional ties. In his book, Emotionally Durable Design: Objects, Experiences & Empathy, Chapman describes how "the process of consumption is, and has always been, motivated by complex emotional drivers, and is about far more than just the mindless purchasing of newer and shinier things; it is a journey towards the ideal or desired self, that through cyclical loops of desire and disappointment, becomes a seemingly endless process of serial destruction". Therefore, a product requires an attribute, or number of attributes, which extend beyond utilitarianism. According to Chapman, "emotional durability" can be achieved through consideration of the following five elements: Narrative: How users share a unique personal history with the product. Consciousness: How the product is perceived as autonomous and in possession of its own free will. Attachment: Can a user be made to feel a strong emotional connection to a product? Fiction: The product inspires interactions and connections beyond just the physical relationship. Surface: How the product ages and develops character through time and use. As a strategic approach, "emotionally durable design provides a useful language to describe the contemporary relevance of designing responsible, well made, tactile products which the user can get to know and assign value to in the long-term". According to Hazel Clark and David Brody of Parsons The New School for Design in New York, "emotionally durable design is a call for professionals and students alike to prioritise the relationships between design and its users, as a way of developing more sustainable attitudes to, and in, design things". Beauty and sustainable design Because standards of sustainable design appear to emphasize ethics over aesthetics, some designers and critics have complained that it lacks inspiration. Pritzker Architecture Prize winner Frank Gehry has called green building "bogus", and National Design Awards winner Peter Eisenman has dismissed it as "having nothing to do with architecture". In 2009, The American Prospect asked whether "well-designed green architecture" is an "oxymoron". Others claim that such criticism of sustainable design is misguided. A leading advocate for this alternative view is architect Lance Hosey, whose book The Shape of Green: Aesthetics, Ecology, and Design (2012) was the first dedicated to the relationships between sustainability and beauty. Hosey argues not just that sustainable design needs to be aesthetically appealing in order to be successful, but also that following the principles of sustainability to their logical conclusion requires reimagining the shape of everything designed, creating things of even greater beauty. Reviewers have suggested that the ideas in The Shape of Green could "revolutionize what it means to be sustainable". Small and large buildings are beginning to successfully incorporate principles of sustainability into award-winning designs. Examples include One Central Park and the Science Faculty building, UTS. The popular Living Building Challenge has incorporated beauty as one of its petals in building design. Sustainable products and processes are required to be beautiful because it allows for emotional durability, which increases the probability that they are going to be maintained and preserved, decreasing their carbon footprint. Many people also argue that biophilia is innately beautiful. Which is why building architecture is designed such that people feel close to nature and is often surrounded by well-kept lawns – a design that is both "beautiful" and encourages the inculcation of nature in our daily lives. Or utilizes daylight design into the system – reducing lighting loads while also fulfilling our need for being close to that which is outdoors. Economic aspects Discussed above, economics is another aspect of it environmental design that is crucial to most design decisions. It is obvious that most people consider the cost of any design before they consider the environmental impacts of it. Therefore, there is a growing nuance of pitching ideas and suggestions for environmentally sustainable design by highlighting the economical profits that they bring to us. "As the green design field matures, it becomes ever more clear that integration is the key to achieving energy and environmental goals especially if cost is a major driver." Building Green Inc. (1999) To achieve the more ambitious goals of the green design movement, architects, engineers and designers need to further embrace and communicate the profit and economic potential of sustainable design measures. Focus should be on honing skills in communicating the economic and profit potential of smart design, with the same rigor that have been applied to advancing technical building solutions. Standards of Evaluation There are several standards and rating systems developed as sustainability gains popularity. Most rating systems revolve around buildings and energy, and some cover products as well. Most rating systems certify on the basis of design as well as post construction or manufacturing. LEED - Leadership in energy and environmental design. Living building challenge HERS - Home energy rating WELS rating - water efficiency labeling standard BREEAM - Building Research Establishment's Environmental Assessment Method GBI - Green Building Initiative EPA WaterSense Energy Star FSC - Forest Stewardship Council CASBEE - Comprehensive Assessment System for Built Environment Efficiency Passive house. Net-Positive Design Net-Positive Design and Assessment computer app While designing for environmental sustainability, it is imperative that the appropriate units are paid attention to. Often, different standards weigh things in different units, and that can make a huge impact on the outcome of the project. Another important aspect of using standards and looking at data involves understanding the baseline. A poor design baseline with huge improvements often show a higher efficiency percentage, while an intelligent baseline from the start might only have a little improvement needed and show lesser change. Therefore, all data should ideally be compared on similar levels, and also be looked at from multiple unit values. Greenwashing Greenwashing is defined to be "the process of conveying a false impression or providing misleading information about how a company's products are more environmentally sound". This can be as simple as using green packaging which subconsciously leads a consumer to think that a product is more environmentally friendly than others. Another example are eco-labels. Companies can take advantage of these certifications for appearance and profit, but their exact meanings are unclear and not readily available. Some labels are more credible than others as they are verified by a credible third-party, while others are self-awarded. The labels are badly regulated and prone to deception. This can lead people to make different decisions on the basis of potentially false narratives. These labels are highly effective as a study in Sweden found that a 32.8% of purchase behavior on ecological food can be determined by the presence of an eco-label. Increased transparency of these labels and recycling labels can empower consumers to make better choices. The methods used by most assessment tools can also result in greenwashing, as explained in Net-Positive Design and Sustainable Urban Development. LCA and Product Life Life cycle assessment is the complete assessment of materials from their extraction, transport, processing, refining, manufacturing, maintenance, use, disposal, reuse and recycle stages. It helps put into perspective whether a design is actually environmentally sustainable in the long run. Products such as aluminum which can be reused multiple number of times but have a very energy intensive mining and refining which makes it unfavorable. Information such as this is done using LCA and then taken into consideration when designing. Applications Applications of this philosophy range from the microcosm — small objects for everyday use, through to the macrocosm — buildings, cities, and the Earth's physical surface. It is a philosophy that can be applied in the fields of architecture, landscape architecture, urban design, urban planning, engineering, graphic design, industrial design, interior design, fashion design and human-computer interaction. Sustainable design is mostly a general reaction to global environmental crises, the rapid growth of economic activity and human population, depletion of natural resources, damage to ecosystems, and loss of biodiversity. In 2013, eco architecture writer Bridgette Meinhold surveyed emergency and long-term sustainable housing projects that were developed in response to these crises in her book, "Urgent Architecture: 40 Sustainable Housing Solutions for a Changing World." Featured projects focus on green building, sustainable design, eco-friendly materials, affordability, material reuse, and humanitarian relief. Construction methods and materials include repurposed shipping containers, straw bale construction, sandbag homes, and floating homes. The limits of sustainable design are shrinking. Because growth in goods and services consistently outpaces gains in efficiency. As a result, the net effect of sustainable design has simply been to improve the efficiency of rapidly increasing impacts. This problem is not solved by the current approach, which focuses on the efficiency of delivering individual goods and services. The fundamental dilemmas are as follows: the increasing complexity of efficiency improvements; the difficulty of implementing new technologies in societies built around old ones; the fact that the physical impacts of delivering goods and services are not localized, but are distributed across economies; and the fact that the scale of resource use is growing and not stabilizing. Sustainable architecture Sustainable architecture is the design of sustainable buildings. Sustainable architecture attempts to reduce the collective environmental impacts during the production of building components, during the construction process, as well as during the lifecycle of the building (heating, electricity use, carpet cleaning etc.) This design practice emphasizes efficiency of heating and cooling systems; alternative energy sources such as solar hot water, appropriate building siting, reused or recycled building materials; on-site power generation - solar technology, ground source heat pumps, wind power; rainwater harvesting for gardening, washing and aquifer recharge; and on-site waste management such as green roofs that filter and control stormwater runoff. This requires close cooperation of the design team, the architects, the engineers, and the client at all project stages, from site selection, scheme formation, material selection and procurement, to project implementation. This is also called a charrette. Appropriate building siting and smaller building footprints are vital to an environmentally sustainable design. Oftentimes, a building may be very well designed, and energy efficient but its location requires people to travel far back and forth – increasing pollution that may not be building produced but is directly as a result of the building anyway. Sustainable architecture must also cover the building beyond its useful life. Its disposal or recycling aspects also come under the wing of sustainability. Often, modular buildings are better to take apart and less energy intensive to put together too. The waste from the demolition site must be disposed of correctly and everything that can be harvested and used again should be designed to be extricated from the structure with ease, preventing unnecessary wastage when decommissioning the building. Another important aspect of sustainable architecture stems from the question of whether a structure is needed. Sometimes the best that can be done to make a structure sustainable is retrofitting or upgrading the building services and supplies instead of tearing it down. Abu Dhabi, for example has undergone and is undergoing major retrofitting to slash its energy and water consumption rather than demolishing and rebuilding new structures. Sustainable architects design with sustainable living in mind. Sustainable vs green design is the challenge that designs not only reflect healthy processes and uses but are powered by renewable energies and site specific resources. A test for sustainable design is — can the design function for its intended use without fossil fuel — unplugged. This challenge suggests architects and planners design solutions that can function without pollution rather than just reducing pollution. As technology progresses in architecture and design theories and as examples are built and tested, architects will soon be able to create not only passive, null-emission buildings, but rather be able to integrate the entire power system into the building design. In 2004 the 59 home housing community, the Solar Settlement, and a integrated retail, commercial and residential building, the Sun Ship, were completed by architect Rolf Disch in Freiburg, Germany. The Solar Settlement is the first housing community worldwide in which every home, all 59, produce a positive energy balance. An essential element of Sustainable Building Design is indoor environmental quality including air quality, illumination, thermal conditions, and acoustics. The integrated design of the indoor environment is essential and must be part of the integrated design of the entire structure. ASHRAE Guideline 10-2011 addresses the interactions among indoor environmental factors and goes beyond traditional standards. Concurrently, the recent movements of New Urbanism and New Classical Architecture promote a sustainable approach towards construction, that appreciates and develops smart growth, architectural tradition and classical design. This in contrast to modernist and globally uniform architecture, as well as leaning against solitary housing estates and suburban sprawl. Both trends started in the 1980s. The Driehaus Architecture Prize is an award that recognizes efforts in New Urbanism and New Classical Architecture, and is endowed with a prize money twice as high as that of the modernist Pritzker Prize. Several advances in sustainable architecture emerged in the late 20th Century that are now widely known by ordinary practitioners. These overlapping but distinct paradigms include Biophilic Urbanism, Permaculture, Biomimicry, Bioregional Planning, Regenerative Design, Circular Systems approaches ranging from Cradle to Cradle product design to the Circular Economy, Nature-Based Design, Net-zero Design, Nature Positive Design, and Net-Positive Design. These paradigms go beyond traditional sustainable design, which simply integrates sustainable design techniques and technologies into conventional urban planning patterns and building design templates. Instead, they represent a broader societal shift (from aiming for resource and energy efficiency) to creating environments that contribute towards net outcomes, such as 'net-positive sustainability'. Net-positive architecture aims to reverse planetary overshoot as well as improving socio-ecological conditions by changing the nature of built environment decision making, design and assessment. Green Design Green design has often been used interchangeably with environmentally sustainable design. It is the practice of creating structures by using environment friendly processes. There is a popular debate about this with several arguing that green design is in effect narrower than sustainable design, which takes into account a larger system. Green design focuses on the short-term goals and while it is a worthy goal, a larger impact is possible using sustainable design. It is included in the process of creating a sustainable design. Another factor to be considered is that green design has been stigmatized by popular personalities such as Pritzker Architecture Prize winner Frank Gehry, but this branding hasn't reached sustainable design. A large part of that is because of how environmentally sustainable design is generally used hand in hand with economically sustainable design and socially sustainable design. Finally, green design is although unintentionally, often associated only with architecture while sustainable design has been considered under a much larger scope. Engineering Design Sustainable engineering is the process of designing or operating systems such that they use energy and resources sustainably, in other words, at a rate that does not compromise the natural environment, or the ability of future generations to meet their own needs. Common engineering focuses revolve around water supply, production, sanitation, cleaning up of pollution and waste sites, restoring natural habitats etc. Sustainable Interior Design Achieving a healthy and aesthetic environment for the occupants of a space is one of the basic rules in the art of Interior design. When applying focus onto the sustainable aspects of the art, Interior Design can incorporate the study and involvement of functionality, accessibility, and aesthetics to environmentally friendly materials. The integrated design of the indoor environment is essential and must be part of the integrated design of the entire structure. Goals of Sustainable Interior Design Improving the overall building performance through the reduction of negative impacts on the environment is the primary goal. According to the Environmental Protection Agency (EPA), Americans spend approximately 90% of their time indoors, where the concentrations of some toxins and impurities are frequently two to five times higher than they are outside. Sustainable interior design solutions strive to create truly inspirational rooms while simultaneously enhancing indoor air quality and mitigating the environmental impact of interior design procedures. This requires interior designers to make ethical design choices and include environmental concerns into their work, as interiors and the environment are closely intertwined. Reducing consumption of non-renewable resources, minimizing waste and creating healthy, productive environments are the primary objectives of sustainability. Optimizing site potential, minimizing non-renewable energy consumption, using environmentally preferable products, protecting and conserving water, enhancing indoor environmental quality, and optimizing operational and maintenance practices are some of the primary principles. An essential element of Sustainable Building Design is indoor environmental quality including air quality, illumination, thermal conditions, and acoustic. Interior design, when done correctly, can harness the true power of sustainable architecture. Incorporating Sustainable Interior Design Sustainable Interior Design can be incorporated through various techniques: water efficiency, energy efficiency, using non-toxic, sustainable or recycled materials, using manufactured processes and producing products with more energy efficiency, building longer lasting and better functioning products, designing reusable and recyclable products, following the sustainable design standards and guidelines, and more. For example, a room with large windows to allow for maximum sunlight should have neutral colored interiors to help bounce the light around and increase comfort levels while reducing light energy requirement. The size should, however, be carefully considered to avoid window glare. Interior Designers must take types of paints, adhesives, and more into consideration during their designing and manufacturing phase so they do not contribute to harmful environmental factors. Choosing whether to use a wood floor to marble tiled floor or carpeted floor can reduce energy consumption by the level of insulation that they provide. Utilizing materials that can withhold 24-hour health care facilities, such as linoleum, scrubbable cotton wall coverings, recycled carpeting, low toxic adhesive, and more. Furthermore, incorporating sustainability can begin before the construction process begins. Purchasing items from sustainable local businesses, analyzing the longevity of a product, taking part in recycling by purchasing recycled materials, and more should be taken into consideration. Supporting local, sustainable businesses is the first step, as this not only increases the demand for sustainable products, but also reduces unsustainable methods. Traveling all over to find specific products or purchasing products from overseas contributes to carbon emissions in the atmosphere, pulling further away from the sustainable aspect. Once the products are found, it is important to check if the selection follows the Cradle-to-cradle design (C2C) method and they are also able to be reclaimed, recycled, and reused. Also paying close attention to energy-efficient products during this entire process contributes to the sustainability factors. The aesthetic of a space does not have to be sacrificed in order to achieve sustainable interior design. Every environment and space can incorporate materials and choices to reducing environmental impact, while still providing durability and functionality. Promotion of Sustainable Interior Design The mission to incorporate sustainable interior design into every aspect of life is slowly becoming a reality. The commercial Interior Design Association (IIDA) created the sustainability forum to encourage, support, and educate the design community and the public about sustainability. The Athena Sustainable Materials Institute ensures enabling smaller footprints by working with sustainability leaders in various ways in producing and consuming materials. Building Green considers themselves the most trusted voice for sustainable and healthy design, as they offer a variety of resources to dive deep into sustainability. Various acts, such as the Energy Policy Act (EPAct) of 2005 and the Energy Independence and Security Act (EISA) of 2007 have been revised and passed to achieve better efforts towards sustainable design. Federal efforts, such as the signing of a Memorandum of Understanding to the commitment of sustainable design and the Executive Order 13693 have also worked to achieve these concepts. Various guideline and standard documents have been published for the sake of sustainable interior design and companies like LEED (Leadership in Energy and Environmental Design) are guiding and certifying efforts put into motion to contribute to the mission. When the thought of incorporating sustainable design into an interior's design is kept as a top goal for a designer, creating an overall healthy and environmentally friendly space can be achieved. Global Examples of Sustainable Interior Design Proximity Hotel in North Carolina, United States of America: The Proximity Hotel was the first hotel to be granted the LEED Platinum certification from the U.S. Green Building Council. Shanghai Natural History Museum in Shanghai, China: This new museum incorporates evaporative cooling and maintained temperatures through is design and structure. Vancouver Convention Centre West in Vancouver, British Columbia, Canada: The West location of the Vancouver Convention Centre was the first convention center in the world to be granted LEED Platinum. Bullitt Center in Seattle, Washington, United States of America: Considered "The Greenest Commercial Building in the World," it is the first to achieve the Living Building Challenge certification. Sydney, Australia became the first city in the country to contribute Green roof and Green wall to their architecture following their "Sustainable Sydney 2030" set of goals. Sustainable urban planning Sustainable design of cities is the task of designing and planning the outline of cities such that they have a low carbon footprint, have better air quality, rely on more sustainable sources of energy, and have a healthy relationship with the environment. Sustainable urban planning involves many disciplines, including architecture, engineering, biology, environmental science, materials science, law, transportation, technology, economic development, accounting and finance, and government, among others. This kind of planning also develops innovative and practical approaches to land use and its impact on natural resources. New sustainable solutions for urban planning problems can include green buildings and housing, mixed-use developments, walkability, greenways and open spaces, alternative energy sources such as solar and wind, and transportation options. Good sustainable land use planning helps improve the welfare of people and their communities, shaping their urban areas and neighborhoods into healthier, more efficient spaces. Design and planning of neighbourhoods are a major challenge when creating a favourable urban environment. The challenge is based on the principles of integrated approach to different demands: social, architectural, artistic, economic, sanitary and hygienic. Social demands are aimed at constructing network and placing buildings in order to create favourable conditions for their convenient use. Architectural-artistic solutions are aimed at single spatial composition of an area with the surrounding landscape. Economic demands include rational utilization of area territories. Sanitary and hygienic demands are of more interest in terms of creating sustainable urban areas. Sustainable landscape and garden design Sustainable landscape architecture is a category of sustainable design and energy-efficient landscaping concerned with the planning and design of outdoor space. Plants and materials may be bought from local growers to reduce energy used in transportation. Design techniques include planting trees to shade buildings from the sun or protect them from wind, using local materials, and on-site composting and chipping not only to reduce green waste hauling but to increase organic matter and therefore carbon in the soil. Some designers and gardeners such as Beth Chatto also use drought-resistant plants in arid areas (xeriscaping) and elsewhere so that water is not taken from local landscapes and habitats for irrigation. Water from building roofs may be collected in rain gardens so that the groundwater is recharged, instead of rainfall becoming surface runoff and increasing the risk of flooding. Areas of the garden and landscape can also be allowed to grow wild to encourage bio-diversity. Native animals may also be encouraged in many other ways: by plants which provide food such as nectar and pollen for insects, or roosting or nesting habitats such as trees, or habitats such as ponds for amphibians and aquatic insects. Pesticides, especially persistent pesticides, must be avoided to avoid killing wildlife. Soil fertility can be managed sustainably by the use of many layers of vegetation from trees to ground-cover plants and mulches to increase organic matter and therefore earthworms and mycorrhiza; nitrogen-fixing plants instead of synthetic nitrogen fertilizers; and sustainably harvested seaweed extract to replace micronutrients. Sustainable landscapes and gardens can be productive as well as ornamental, growing food, firewood and craft materials from beautiful places. Sustainable landscape approaches and labels include organic farming and growing, permaculture, agroforestry, forest gardens, agroecology, vegan organic gardening, ecological gardening and climate-friendly gardening. Sustainable agriculture Sustainable agriculture adheres to three main goals: Environmental health, Economic profitability, Social and economic equity. A variety of philosophies, policies and practices have contributed to these goals. People in many different capacities, from farmers to consumers, have shared this vision and contributed to it. Despite the diversity of people and perspectives, the following themes commonly weave through definitions of sustainable agriculture. There are strenuous discussions — among others by the agricultural sector and authorities — if existing pesticide protocols and methods of soil conservation adequately protect topsoil and wildlife. Doubt has risen if these are sustainable, and if agrarian reforms would permit an efficient agriculture with fewer pesticides, therefore reducing the damage to the ecosystem. Energy sector Sustainable technology in the energy sector is based on utilizing renewable sources of energy such as solar, wind, hydro, bioenergy, geothermal, and hydrogen. Wind energy is the world's fastest growing energy source; it has been in use for centuries in Europe and more recently in the United States and other nations. Wind energy is captured through the use of wind turbines that generate and transfer electricity for utilities, homeowners and remote villages. Solar power can be harnessed through photovoltaics, concentrating solar, or solar hot water and is also a rapidly growing energy source. Advancements in the technology and modifications to photovoltaics cells provide a more in depth untouched method for creating and producing solar power. Researchers have found a potential way to use the photogalvanic effect to transform sunlight into electric energy. The availability, potential, and feasibility of primary renewable energy resources must be analyzed early in the planning process as part of a comprehensive energy plan. The plan must justify energy demand and supply and assess the actual costs and benefits to the local, regional, and global environments. Responsible energy use is fundamental to sustainable development and a sustainable future. Energy management must balance justifiable energy demand with appropriate energy supply. The process couples energy awareness, energy conservation, and energy efficiency with the use of primary renewable energy resources. Water sector Sustainable water technologies have become an important industry segment with several companies now providing important and scalable solutions to supply water in a sustainable manner. Beyond the use of certain technologies, Sustainable Design in Water Management also consists very importantly in correct implementation of concepts. Among these principal concepts is the fact normally in developed countries 100% of water destined for consumption, that is not necessarily for drinking purposes, is of potable water quality. This concept of differentiating qualities of water for different purposes has been called "fit-for-purpose". This more rational use of water achieves several economies, that are not only related to water itself, but also the consumption of energy, as to achieve water of drinking quality can be extremely energy intensive for several reasons. Domestic machinery and furniture Automobiles, home appliances and furnitures can be designed for repair and disassembly (for recycling), and constructed from recyclable materials such as steel, aluminum and glass, and renewable materials, such as wood and plastics from natural feedstocks. Careful selection of materials and manufacturing processes can often create products comparable in price and performance to non-sustainable products. Even mild design efforts can greatly increase the sustainable content of manufactured items. Improvements to heating, cooling, ventilation and water heating Absorption refrigerator Annualized geothermal solar Earth cooling tubes Geothermal heat pump Heat recovery ventilation Hot water heat recycling Passive cooling Renewable heat Seasonal thermal energy storage (STES) Solar air conditioning Solar hot water Superinsulation Design for sustainable manufacturing Sustainable manufacturing can be defined as the creation of a manufactured product through a concurrent improvement in the resulting effect on factory and product sustainability. The concept of sustainable manufacturing demands a renewed design of production systems in order to condition the related sustainability on product life cycle and Factory operations. Designing sustainable production systems imply, on the one hand, the analysis and optimization of intra-factory aspects that are related to manufacturing plants. Such aspects can regard the resource consumption restrain, the process efficiency, the ergonomics for the factory workers, the elimination of hazardous substances, the minimization of factory emissions and waste as well as internal emissions, the integrated management of information in the production facilities, and the technological updating of machines and plants. Other inter-factories aspects concern the sustainable design of manufactured products, product chain dematerialisation, management of the background and foreground supply chains, support of circular economy paradigm, and the labelling for sustainability. Advantageous reasons for why companies might choose to sustainably manufacture either their products or use a sustainable manufacturing process are: Increase operational efficiency by reducing costs and waste Respond to or reach new customers and increase competitive advantage Protect and strengthen brand and reputation and build public trust Build long-term business viability and success Respond to regulatory constraints and opportunities Sustainable technologies Sustainable technologies use less energy, fewer limited resources, do not deplete natural resources, do not directly or indirectly pollute the environment, and can be reused or recycled at the end of their useful life. They may also be technology that help identify areas of growth by giving feedback in terms of data or alerts allowed to be analyzed to improve environmental footprints. There is significant overlap with appropriate technology, which emphasizes the suitability of technology to the context, in particular considering the needs of people in developing countries. The most appropriate technology may not be the most sustainable one; and a sustainable technology may have high cost or maintenance requirements that make it unsuitable as an "appropriate technology", as that term is commonly used. "Technology is deeply entrenched in our society; without it, society would immediately collapse. Moreover, technological changes can be perceived as easier to accomplish than lifestyle changes that might be required to solve the problems that we face." The design of sustainable technology relies heavily on the flow of new information. Sustainable technology such as smart metering systems and intelligent sensors reduce energy consumption and help conserve water. These systems are ones that have more fundamental changes, rather than just switching to simple sustainable designs. Such designing requires constant updates and evolutions, to ensure true environmental sustainability, because the concept of sustainability is ever changing – with regards to our relationship with the environment. A large part of designing sustainable technology involves giving control to the users for their comfort and operation. For example, dimming controls help people adjust the light levels to their comfort. Sectioned lighting and lighting controls let people manipulate their lighting needs without worrying about affecting others – therefore reducing lighting loads. Innovation and development The precursor step to environmentally sustainable development must be a sustainable design. By definition, design is defined as purpose, planning, or intention that exists or is thought to exist behind an action, fact, or material object. Development utilizes design and executes it, helping areas, cities, or places to advance. Sustainable development is that development which adheres to the values of sustainability and provide for the society without endangering the ecosystem and its services. "Without development, design is useless. Without design, development is unusable." – Florian Popescu, How to bridge the gap between design and development. Eco-innovation is the design and development of products and processes that contribute to sustainable development, applying the commercial application of knowledge to elicit direct or indirect ecological improvements. This includes a range of related ideas, from environmentally friendly technological advances to socially acceptable innovative paths towards sustainability. WIPO GREEN is an online global marketplace for technology exchange connecting providers and seekers of inventions and innovations in sustainable technology innovations. Several factors drive design innovation in the environmental sphere. These include growing consumer awareness and demand for green products and services, development and (re)discovery of renewable materials, sustainable refurbishment, new technologies for manufacturing and growing use of artificial intelligence-based tools based to map needs and identify areas for improved efficiency. Whatever the industry or product, design rights (whether registered or unregistered) can harness innovative design. Design rights (known as design patents in some jurisdictions) are widely used to protect everything from marketing logos and packaging to the shape of furniture and vehicles and the user interfaces of computers and smartphones. Design rights are available in many jurisdictions and through regional systems. Protection can also be obtained internationally using the WIPO-administered Hague System for the International Registration of Designs.

Terraforming of Mars

The terraforming of Mars or the terraformation of Mars is a hypothetical procedure that would consist of a planetary engineering project or concurrent projects aspiring to transform Mars from a planet hostile to terrestrial life to one that could sustainably host humans and other lifeforms free of protection or mediation. The process would involve the modification of the planet's extant climate, atmosphere, and surface through a variety of resource-intensive initiatives, as well as the installation of a novel ecological system or systems. Justifications for choosing Mars over other potential terraforming targets include the presence of water and a geological history that suggests it once harbored a dense atmosphere similar to Earth's. Hazards and difficulties include low gravity, toxic soil, low light levels relative to Earth's, and the lack of a magnetic field. Disagreement exists about whether current technology could render the planet habitable. Reasons for objecting to terraforming include ethical concerns about terraforming and the considerable cost that such an undertaking would involve. Reasons for terraforming the planet include allaying concerns about resource use and depletion on Earth and arguments that the altering and subsequent or concurrent settlement of other planets decreases the odds of humanity's extinction. Motivation and side effects Future population growth, demand for resources, and an alternate solution to the Doomsday argument may require human colonization of bodies other than Earth, such as Mars, the Moon, and other objects. Space colonization would facilitate harvesting the Solar System's energy and material resources. In many aspects, Mars is the most Earth-like of all the other planets in the Solar System. It is thought that Mars had a more Earth-like environment early in its geological history, with a thicker atmosphere and abundant water that was lost over the course of hundreds of millions of years through atmospheric escape. Given the foundations of similarity and proximity, Mars would make one of the most plausible terraforming targets in the Solar System. Side effects of terraforming include the potential displacement or destruction of any indigenous life if such life exists. Challenges and limitations The Martian environment presents several terraforming challenges to overcome and the extent of terraforming may be limited by certain key environmental factors. The process of terraforming aims to mitigate the following distinctions between Mars and Earth, among others: Reduced light levels (about 60% of Earth) Low surface gravity (38% of Earth's) Unbreathable atmosphere Low atmospheric pressure (about 1% of Earth's; well below the Armstrong limit) Ionizing solar and cosmic radiation at the surface Average temperature compared to Earth average of ) Molecular instability - bonds between atoms break down in critical molecules such as organic compounds Global dust storms No natural food source Toxic soil No global magnetic field to shield against the solar wind Countering the effects of space weather Mars has no intrinsic global magnetic field, but the solar wind directly interacts with the atmosphere of Mars, leading to the formation of a magnetosphere from magnetic field tubes. This poses challenges for mitigating solar radiation and retaining an atmosphere. The lack of a magnetic field, its relatively small mass, and its atmospheric photochemistry, all would have contributed to the evaporation and loss of its surface liquid water over time. Solar wind–induced ejection of Martian atmospheric atoms has been detected by Mars-orbiting probes, indicating that the solar wind has stripped the Martian atmosphere over time. For comparison, while Venus has a dense atmosphere, it has only traces of water vapor (20 ppm) as it lacks a large, dipole-induced, magnetic field. Earth's ozone layer provides additional protection. Ultraviolet light is blocked before it can dissociate water into hydrogen and oxygen. Low gravity and pressure The surface gravity on Mars is 38% of that on Earth. It is not known if this is enough to prevent the health problems associated with weightlessness. Mars's atmosphere has about 1% the pressure of the Earth's at sea level. It is estimated that there is sufficient ice in the regolith and the south polar cap to form a atmosphere if it is released by planetary warming. The reappearance of liquid water on the Martian surface would add to the warming effects and atmospheric density, but the lower gravity of Mars requires 2.6 times Earth's column airmass to obtain the optimum pressure at the surface. Additional volatiles to increase the atmosphere's density must be supplied from an external source, such as redirecting several massive asteroids (40-400 billion tonnes total) containing ammonia as a source of nitrogen. Breathing on Mars Current conditions in the Martian atmosphere, at less than of atmospheric pressure, are significantly below the Armstrong limit of where very low pressure causes exposed bodily liquids such as saliva, tears, and the liquids wetting the alveoli within the lungs to boil away. Without a pressure suit, no amount of breathable oxygen delivered by any means will sustain oxygen-breathing life for more than a few minutes. In the NASA technical report Rapid (Explosive) Decompression Emergencies in Pressure-Suited Subjects, after exposure to pressure below the Armstrong limit, a survivor reported that his "last conscious memory was of the water on his tongue beginning to boil". In these conditions humans die within minutes unless a pressure suit provides life support. If Mars' atmospheric pressure could rise above , then a pressure suit would not be required. Visitors would only need to wear a mask that supplied 100% oxygen under positive pressure. A further increase to of atmospheric pressure would allow a simple mask supplying pure oxygen. This might look similar to mountain climbers who venture into pressures below , also called the death zone, where an insufficient amount of bottled oxygen has often resulted in hypoxia with fatalities. However, if the increase in atmospheric pressure was achieved by increasing CO2 (or other toxic gas) the mask would have to ensure the external atmosphere did not enter the breathing apparatus. CO2 concentrations as low as 1% cause drowsiness in humans. Concentrations of 7% to 10% may cause suffocation, even in the presence of sufficient oxygen. (See Carbon dioxide toxicity.) In 2021, the NASA Mars rover Perseverance was able to make oxygen on Mars. However, the process is complex and takes a considerable amount of time to produce a small amount of oxygen. Advantages According to scientists, Mars exists on the outer edge of the habitable zone, a region of the Solar System where liquid water on the surface may be supported if concentrated greenhouse gases could increase the atmospheric pressure. The lack of both a magnetic field and geologic activity on Mars may be a result of its relatively small size, which allowed the interior to cool more quickly than Earth's, although the details of such a process are still not well understood. There are strong indications that Mars once had an atmosphere as thick as Earth's during an earlier stage in its development, and that its pressure supported abundant liquid water at the surface. Although water appears to have once been present on the Martian surface, ground ice currently exists from mid-latitudes to the poles. The soil and atmosphere of Mars contain many of the main elements crucial to life, including sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon. Any climate change induced in the near term is likely to be driven by greenhouse warming produced by an increase in atmospheric carbon dioxide and a consequent increase in atmospheric water vapor. These two gases are the only likely sources of greenhouse warming that are available in large quantities in Mars' environment. Large amounts of water ice exist below the Martian surface, as well as on the surface at the poles, where it is mixed with dry ice, frozen . Significant amounts of water are located at the south pole of Mars, which, if melted, would correspond to a planetwide ocean 5–11 meters deep. Frozen carbon dioxide at the poles sublimes into the atmosphere during the Martian summers, and small amounts of water residue are left behind, which fast winds sweep off the poles at speeds approaching . This seasonal occurrence transports large amounts of dust and water ice into the atmosphere, forming Earth-like ice clouds. Most of the oxygen in the Martian atmosphere is present as carbon dioxide, the main atmospheric component. Molecular oxygen (O2) only exists in trace amounts. Large amounts of oxygen can be also found in metal oxides on the Martian surface, and in the soil, in the form of per-nitrates. An analysis of soil samples taken by the Phoenix lander indicated the presence of perchlorate, which has been used to liberate oxygen in chemical oxygen generators. Electrolysis could be employed to separate water on Mars into oxygen and hydrogen if sufficient liquid water and electricity were available. However, if vented into the atmosphere it would escape into space. Proposed methods and strategies Terraforming Mars would entail three major interlaced changes: building up the magnetosphere, building up the atmosphere, and raising the temperature. The atmosphere of Mars is relatively thin and has a very low surface pressure. Because its atmosphere consists mainly of , a known greenhouse gas, once Mars begins to heat, the may help to keep thermal energy near the surface. Moreover, as it heats, more should enter the atmosphere from the frozen reserves on the poles, enhancing the greenhouse effect. This means that the two processes of building the atmosphere and heating it would augment each other, favoring terraforming. However, it would be difficult to keep the atmosphere together because of the lack of a protective global magnetic field against erosion by the solar wind. Importing ammonia One method of augmenting the Martian atmosphere is to introduce ammonia (NH3). Large amounts of ammonia are likely to exist in frozen form on minor planets orbiting in the outer Solar System. It might be possible to redirect the orbits of these or smaller ammonia-rich objects so that they collide with Mars, thereby transferring the ammonia into the Martian atmosphere. Ammonia is not stable in the Martian atmosphere, however. It breaks down into (diatomic) nitrogen and hydrogen after a few hours. Thus, though ammonia is a powerful greenhouse gas, it is unlikely to generate much planetary warming. Presumably, the nitrogen gas would eventually be depleted by the same processes that stripped Mars of much of its original atmosphere, but these processes are thought to have required hundreds of millions of years. Being much lighter, the hydrogen would be removed much more quickly. Carbon dioxide is 2.5 times the density of ammonia, and nitrogen gas, which Mars barely holds on to, is more than 1.5 times the density, so any imported ammonia that did not break down would also be lost quickly into space. Importing hydrocarbons Another way to create a Martian atmosphere would be to import methane (CH4) or other hydrocarbons, which are common in Titan's atmosphere and on its surface; the methane could be vented into the atmosphere where it would act to compound the greenhouse effect. However, like ammonia (NH3), methane (CH4) is a relatively light gas. It is in fact even less dense than ammonia and so would similarly be lost into space if it was introduced, and at a faster rate than ammonia. Even if a method could be found to prevent it escaping into space, methane can exist in the Martian atmosphere for only a limited period before it is destroyed. Estimates of its lifetime range from 0.6–4 years. Use of fluorine compounds Especially powerful greenhouse gases, such as sulfur hexafluoride, chlorofluorocarbons (CFCs), or perfluorocarbons (PFCs), have been suggested both as a means of initially warming Mars and of maintaining long-term climate stability. These gases are proposed for introduction because they generate a greenhouse effect thousands of times stronger than that of . Fluorine-based compounds such as sulphur hexafluoride and perfluorocarbons are preferable to chlorine-based ones as the latter destroys ozone. It has been estimated that approximately 0.3 microbars of CFCs would need to be introduced into Mars' atmosphere to sublimate the south polar glaciers. This is equivalent to a mass of approximately 39 million tonnes, that is, about three times the amount of CFCs manufactured on Earth from 1972 to 1992 (when CFC production was banned by international treaty). Maintaining the temperature would require continual production of such compounds as they are destroyed due to photolysis. It has been estimated that introducing 170 kilotons of optimal greenhouse compounds (CF3CF2CF3, CF3SCF2CF3, SF6, SF5CF3, SF4(CF3)2) annually would be sufficient to maintain a 70-K greenhouse effect given a terraformed atmosphere with earth-like pressure and composition. Typical proposals envision producing the gases on Mars using locally extracted materials, nuclear power, and a significant industrial effort. The potential for mining fluorine-containing minerals to obtain the raw material necessary for the production of CFCs and PFCs is supported by mineralogical surveys of Mars that estimate the elemental presence of fluorine in the bulk composition of Mars at 32 ppm by mass (as compared to 19.4 ppm for the Earth). Alternatively, CFCs might be introduced by sending rockets with payloads of compressed CFCs on collision courses with Mars. When the rockets crashed into the surface they would release their payloads into the atmosphere. A steady barrage of these "CFC rockets" would need to be sustained for a little over a decade while Mars is changed chemically and becomes warmer. Use of conductive nanorods A 2024 study proposed using nanorods consisting of a conductive material, such as aluminum or iron, made by processing Martian minerals. These nanorods would scatter and absorb the thermal infrared upwelling from the surface, thus warming the planet. This process is claimed to be over 5,000 times more effective (in terms of warming per unit mass) than warming using fluorine compounds. Use of orbital mirrors Mirrors made of thin aluminized PET film could be placed in orbit around Mars to increase the total insolation it receives. This would direct the sunlight onto the surface and could increase Mars's surface temperature directly. The 125 km radius mirror could be positioned as a statite, using its effectiveness as a solar sail to orbit in a stationary position relative to Mars, near the poles, to sublimate the ice sheet and contribute to the warming greenhouse effect. However, certain problems have been found with this. The main concern is the difficulty of launching large mirrors from Earth. Use of nuclear weapons Elon Musk has proposed terraforming Mars by detonating nuclear weapons on the Martian polar ice caps to vaporize them and release carbon dioxide and water vapor into the atmosphere. Carbon dioxide and water vapor are greenhouse gases, and the resultant thicker atmosphere would trap heat from the Sun, increasing the planet's temperature. The formation of liquid water could be very favorable for oxygen-producing plants, and thus, human survival. Studies suggest that even if all the CO2 trapped in Mars' polar ice and regolith were released, it would not be enough to provide significant greenhouse warming to turn Mars into an Earth-like planet. Another criticism is that it would stir up enough dust and particles to block out a significant portion of the incoming sunlight, causing a nuclear winter, the opposite of the goal. Albedo reduction Reducing the albedo of the Martian surface would also make more efficient use of incoming sunlight in terms of heat absorption. This could be done by spreading dark dust from Mars's moons, Phobos and Deimos, which are among the blackest bodies in the Solar System; or by introducing dark extremophile microbial life forms such as lichens, algae and bacteria. The ground would then absorb more sunlight, warming the atmosphere. However, Mars is already the second-darkest planet in the solar system, absorbing over 70% of incoming sunlight so the scope for darkening it further is small. If algae or other green life were established, it would also contribute a small amount of oxygen to the atmosphere, though not enough to allow humans to breathe. The conversion process to produce oxygen is highly reliant upon water, without which the is mostly converted to carbohydrates. In addition, because on Mars atmospheric oxygen is lost into space (unless an artificial magnetosphere were to be created; see "Protecting the atmosphere" below), such life would need to be cultivated inside a closed system. On April 26, 2012, scientists reported that lichen survived and showed remarkable results on the adaptation capacity of photosynthetic activity within the simulation time of 34 days under Martian conditions in the Mars Simulation Laboratory (MSL) maintained by the German Aerospace Center (DLR). One final issue with albedo reduction is the common Martian dust storms. These cover the entire planet for weeks, and not only increase the albedo, but block sunlight from reaching the surface. This has been observed to cause a surface temperature drop which the planet takes months to recover from. Once the dust settles it then covers whatever it lands on, effectively erasing the albedo reduction material from the view of the Sun. Funded research: ecopoiesis Since 2014, the NASA Institute for Advanced Concepts (NIAC) program and Techshot Inc have been working together to develop sealed biodomes that would employ colonies of oxygen-producing cyanobacteria and algae for the production of molecular oxygen (O2) on Martian soil. But first they need to test if it works on a small scale on Mars. The proposal is called Mars Ecopoiesis Test Bed. Eugene Boland is the Chief Scientist at Techshot, a company located in Greenville, Indiana. They intend to send small canisters of extremophile photosynthetic algae and cyanobacteria aboard a future rover mission. The rover would cork-screw the canisters into selected sites likely to experience transients of liquid water, drawing some Martian soil and then release oxygen-producing microorganisms to grow within the sealed soil. The hardware would use Martian subsurface ice as its phase changes into liquid water. The system would then look for oxygen given off as metabolic byproduct and report results to a Mars-orbiting relay satellite. If this experiment works on Mars, they will propose to build several large and sealed structures called biodomes, to produce and harvest oxygen for a future human mission to Mars life support systems. Being able to create oxygen there would provide considerable cost-savings to NASA and allow for longer human visits to Mars than would be possible if astronauts have to transport their own heavy oxygen tanks. This biological process, called ecopoiesis, would be isolated, in contained areas, and is not meant as a type of global planetary engineering for terraforming of Mars's atmosphere, but NASA states that "This will be the first major leap from laboratory studies into the implementation of experimental (as opposed to analytical) planetary in situ research of greatest interest to planetary biology, ecopoiesis, and terraforming." Research at the University of Arkansas presented in June 2015 suggested that some methanogens could survive in Mars's low pressure. Rebecca Mickol found that in her laboratory, four species of methanogens survived low-pressure conditions that were similar to a subsurface liquid aquifer on Mars. The four species that she tested were Methanothermobacter wolfeii, Methanosarcina barkeri, Methanobacterium formicicum, and Methanococcus maripaludis. Methanogens do not require oxygen or organic nutrients, are non-photosynthetic, use hydrogen as their energy source and carbon dioxide (CO2) as their carbon source, so they could exist in subsurface environments on Mars. Protecting the atmosphere One key aspect of terraforming Mars is to protect the atmosphere (both present and future-built) from being lost into space. Some scientists hypothesize that creating a planet-wide artificial magnetosphere would be helpful in resolving this issue. According to two NIFS Japanese scientists, it is feasible to do that with current technology by building a system of refrigerated latitudinal superconducting rings, each carrying a sufficient amount of direct current. In the same report, it is claimed that the economic impact of the system can be minimized by using it also as a planetary energy transfer and storage system (SMES). Magnetic shield at L1 orbit During the Planetary Science Vision 2050 Workshop in late February 2017, NASA scientist Jim Green proposed a concept of placing a magnetic dipole field between the planet and the Sun to protect it from high-energy solar particles. It would be located at the Mars Lagrange orbit L1 at about 320 R♂, creating a partial and distant artificial magnetosphere. The field would need to be "Earth comparable" and sustain as measured at 1 Earth-radius. The paper abstract cites that this could be achieved by a magnet with a strength of . If constructed, the shield may allow the planet to partially restore its atmosphere. Plasma torus along the orbit of Phobos A plasma torus along the orbit of Phobos by ionizing and accelerating particles from the moon may be sufficient to create a magnetic field strong enough to protect a terraformed Mars. Thermodynamics of terraforming The overall energy required to sublimate the from the south polar ice cap was modeled by Zubrin and McKay in 1993. If using orbital mirrors, an estimated 120 MW-years of electrical energy would be required to produce mirrors large enough to vaporize the ice caps. This is considered the most effective method, though the least practical. If using powerful halocarbon greenhouse gases, an order of 1,000 MW-years of electrical energy would be required to accomplish this heating. However, if all of this were put into the atmosphere, it would only double the current atmospheric pressure from 6 mbar to 12 mbar, amounting to about 1.2% of Earth's mean sea level pressure. The amount of warming that could be produced today by putting even 100 mbar of into the atmosphere is small, roughly of order . Additionally, once in the atmosphere, it likely would be removed quickly, either by diffusion into the subsurface and adsorption or by re-condensing onto the polar caps. The surface or atmospheric temperature required to allow liquid water to exist has not been determined, and liquid water conceivably could exist when atmospheric temperatures are as low as . However, a warming of is much less than thought necessary to produce liquid water.

Human impact on the environment

Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society (as in the built environment) is causing severe effects including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, neoliberal economic policies and rapid economic growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species. The term anthropogenic designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it was first used in English by British ecologist Arthur Tansley in reference to human influences on climax plant communities. The atmospheric scientist Paul Crutzen introduced the term "Anthropocene" in the mid-1970s. The term is sometimes used in the context of pollution produced from human activity since the start of the Agricultural Revolution but also applies broadly to all major human impacts on the environment. Many of the actions taken by humans that contribute to a heated environment stem from the burning of fossil fuel from a variety of sources, such as: electricity, cars, planes, space heating, manufacturing, or the destruction of forests. Human overshoot Overconsumption Overconsumption is a situation where resource use has outpaced the sustainable capacity of the ecosystem. It can be measured by the ecological footprint, a resource accounting approach which compares human demand on ecosystems with the amount of planet matter ecosystems can renew. Estimates by the Global Footprint Network indicate that humanity's current demand is 70% higher than the regeneration rate of all of the planet's ecosystems combined. A prolonged pattern of overconsumption leads to environmental degradation and the eventual loss of resource bases. Humanity's overall impact on the planet is affected by many factors, not just the raw number of people. Their lifestyle (including overall affluence and resource use) and the pollution they generate (including carbon footprint) are equally important. In 2008, The New York Times stated that the inhabitants of the developed nations of the world consume resources like oil and metals at a rate almost 32 times greater than those of the developing world, who make up the majority of the human population. Human civilization has caused the loss of 83% of all wild mammals and half of plants. The world's chickens are triple the weight of all the wild birds, while domesticated cattle and pigs outweigh all wild mammals by 14 to 1. Global meat consumption is projected to more than double by 2050, perhaps as much as 76%, as the global population rises to more than 9 billion, which will be a significant driver of further biodiversity loss and increased Greenhouse gas emissions. Population growth and size Some scholars, environmentalists and advocates have linked human population growth or population size as a driver of environmental issues, including some suggesting this indicates an overpopulation scenario. In 2017, over 15,000 scientists around the world issued a second warning to humanity which asserted that rapid human population growth is the "primary driver behind many ecological and even societal threats." According to the Global Assessment Report on Biodiversity and Ecosystem Services, released by the United Nations' Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services in 2019, human population growth is a significant factor in contemporary biodiversity loss. A 2021 report in Frontiers in Conservation Science proposed that population size and growth are significant factors in biodiversity loss, soil degradation and pollution. Some scientists and environmentalists, including Pentti Linkola, Jared Diamond and E. O. Wilson, posit that human population growth is devastating to biodiversity. Wilson for example, has expressed concern that when Homo sapiens reached a population of six billion their biomass exceeded that of any other large land dwelling animal species that had ever existed by over 100 times. However, attributing overpopulation as a cause of environmental issues is controversial. Demographic projections indicate that population growth is slowing and world population will peak in the 21st century, and many experts believe that global resources can meet this increased demand, suggesting a global overpopulation scenario is unlikely. Other projections have the population continuing to grow into the next century. While some studies, including the British government's 2021 Economics of Biodiversity review, posit that population growth and overconsumption are interdependent, critics suggest blaming overpopulation for environmental issues can unduly blame poor populations in the Global South or oversimplify more complex drivers, leading some to treat overconsumption as a separate issue. Advocates for further reducing fertility rates, among them Rodolfo Dirzo and Paul R. Ehrlich, argue that this reduction should primarily affect the "overconsuming wealthy and middle classes," with the ultimate goal being to shrink "the scale of the human enterprise" and reverse the "growthmania" which they say threatens biodiversity and the "life-support systems of humanity." Fishing and farming The environmental impact of agriculture varies based on the wide variety of agricultural practices employed around the world. Ultimately, the environmental impact depends on the production practices of the system used by farmers. The connection between emissions into the environment and the farming system is indirect, as it also depends on other climate variables such as rainfall and temperature. There are two types of indicators of environmental impact: "means-based", which is based on the farmer's production methods, and "effect-based", which is the impact that farming methods have on the farming system or on emissions to the environment. An example of a means-based indicator would be the quality of groundwater that is affected by the amount of nitrogen applied to the soil. An indicator reflecting the loss of nitrate to groundwater would be effect-based. The environmental impact of agriculture involves a variety of factors from the soil, to water, the air, animal and soil diversity, plants, and the food itself. Some of the environmental issues that are related to agriculture are climate change, deforestation, genetic engineering, irrigation problems, pollutants, soil degradation, and waste. Fishing The environmental impact of fishing can be divided into issues that involve the availability of fish to be caught, such as overfishing, sustainable fisheries, and fisheries management; and issues that involve the impact of fishing on other elements of the environment, such as by-catch and destruction of habitat such as coral reefs. According to the 2019 Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services report, overfishing is the main driver of mass species extinction in the oceans. These conservation issues are part of marine conservation, and are addressed in fisheries science programs. There is a growing gap between how many fish are available to be caught and humanity's desire to catch them, a problem that gets worse as the world population grows. Similar to other environmental issues, there can be conflict between the fishermen who depend on fishing for their livelihoods and fishery scientists who realize that if future fish populations are to be sustainable then some fisheries must reduce or even close. The journal Science published a four-year study in November 2006, which predicted that, at prevailing trends, the world would run out of wild-caught seafood in 2048. The scientists stated that the decline was a result of overfishing, pollution and other environmental factors that were reducing the population of fisheries at the same time as their ecosystems were being degraded. Yet again the analysis has met criticism as being fundamentally flawed, and many fishery management officials, industry representatives and scientists challenge the findings, although the debate continues. Many countries, such as Tonga, the United States, Australia and New Zealand, and international management bodies have taken steps to appropriately manage marine resources. The UN's Food and Agriculture Organization (FAO) released their biennial State of World Fisheries and Aquaculture in 2018 noting that capture fishery production has remained constant for the last two decades but unsustainable overfishing has increased to 33% of the world's fisheries. They also noted that aquaculture, the production of farmed fish, has increased from 120 million tonnes per year in 1990 to over 170 million tonnes in 2018. Populations of oceanic sharks and rays have been reduced by 71% since 1970, largely due to overfishing. More than three-quarters of the species comprising this group are now threatened with extinction. Irrigation The environmental impact of irrigation includes the changes in quantity and quality of soil and water as a result of irrigation and the ensuing effects on natural and social conditions at the tail-end and downstream of the irrigation scheme. The impacts stem from the changed hydrological conditions owing to the installation and operation of the scheme. An irrigation scheme often draws water from the river and distributes it over the irrigated area. As a hydrological result it is found that: the downstream river discharge is reduced the evaporation in the scheme is increased the groundwater recharge in the scheme is increased the level of the water table rises the drainage flow is increased. These may be called direct effects. Effects on soil and water quality are indirect and complex, and subsequent impacts on natural, ecological and socio-economic conditions are intricate. In some, but not all instances, water logging and soil salinization can result. However, irrigation can also be used, together with soil drainage, to overcome soil salinization by leaching excess salts from the vicinity of the root zone. Irrigation can also be done extracting groundwater by (tube)wells. As a hydrological result it is found that the level of the water descends. The effects may be water mining, land/soil subsidence, and, along the coast, saltwater intrusion. Irrigation projects can have large benefits, but the negative side effects are often overlooked. Agricultural irrigation technologies such as high powered water pumps, dams, and pipelines are responsible for the large-scale depletion of fresh water resources such as aquifers, lakes, and rivers. As a result of this massive diversion of freshwater, lakes, rivers, and creeks are running dry, severely altering or stressing surrounding ecosystems, and contributing to the extinction of many aquatic species. Agricultural land loss Lal and Stewart estimated global loss of agricultural land by degradation and abandonment at 12 million hectares per year. In contrast, according to Scherr, GLASOD (Global Assessment of Human-Induced Soil Degradation, under the UN Environment Programme) estimated that 6 million hectares of agricultural land per year had been lost to soil degradation since the mid-1940s, and she noted that this magnitude is similar to earlier estimates by Dudal and by Rozanov et al. Such losses are attributable not only to soil erosion, but also to salinization, loss of nutrients and organic matter, acidification, compaction, water logging and subsidence. Human-induced land degradation tends to be particularly serious in dry regions. Focusing on soil properties, Oldeman estimated that about 19 million square kilometers of global land area had been degraded; Dregne and Chou, who included degradation of vegetation cover as well as soil, estimated about 36 million square kilometers degraded in the world's dry regions. Despite estimated losses of agricultural land, the amount of arable land used in crop production globally increased by about 9% from 1961 to 2012, and is estimated to have been 1.396 billion hectares in 2012. Global average soil erosion rates are thought to be high, and erosion rates on conventional cropland generally exceed estimates of soil production rates, usually by more than an order of magnitude. In the US, sampling for erosion estimates by the US NRCS (Natural Resources Conservation Service) is statistically based, and estimation uses the Universal Soil Loss Equation and Wind Erosion Equation. For 2010, annual average soil loss by sheet, rill and wind erosion on non-federal US land was estimated to be 10.7 t/ha on cropland and 1.9 t/ha on pasture land; the average soil erosion rate on US cropland had been reduced by about 34% since 1982. No-till and low-till practices have become increasingly common on North American cropland used for production of grains such as wheat and barley. On uncultivated cropland, the recent average total soil loss has been 2.2 t/ha per year. In comparison with agriculture using conventional cultivation, it has been suggested that, because no-till agriculture produces erosion rates much closer to soil production rates, it could provide a foundation for sustainable agriculture. Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable. Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush fires. This is considered to be an important topic of the 21st century due to the implications land degradation has upon agronomic productivity, the environment, and its effects on food security. It is estimated that up to 40% of the world's agricultural land is seriously degraded. Meat production Environmental impacts associated with meat production include use of fossil energy, water and land resources, greenhouse gas emissions, and in some instances, rainforest clearing, water pollution and species endangerment, among other adverse effects. Steinfeld et al. of the FAO estimated that 18% of global anthropogenic GHG (greenhouse gas) emissions (estimated as 100-year carbon dioxide equivalents) are associated in some way with livestock production. FAO data indicate that meat accounted for 26% of global livestock product tonnage in 2011. Globally, enteric fermentation (mostly in ruminant livestock) accounts for about 27% of anthropogenic methane emissions, Despite methane's 100-year global warming potential, recently estimated at 28 without and 34 with climate-carbon feedbacks, methane emission is currently contributing relatively little to global warming. Although reduction of methane emissions would have a rapid effect on warming, the expected effect would be small. Other anthropogenic GHG emissions associated with livestock production include carbon dioxide from fossil fuel consumption (mostly for production, harvesting and transport of feed), and nitrous oxide emissions associated with the use of nitrogenous fertilizers, growing of nitrogen-fixing legume vegetation and manure management. Management practices that can mitigate GHG emissions from production of livestock and feed have been identified. Considerable water use is associated with meat production, mostly because of water used in production of vegetation that provides feed. There are several published estimates of water use associated with livestock and meat production, but the amount of water use assignable to such production is seldom estimated. For example, "green water" use is evapotranspirational use of soil water that has been provided directly by precipitation; and "green water" has been estimated to account for 94% of global beef cattle production's "water footprint", and on rangeland, as much as 99.5% of the water use associated with beef production is "green water". Impairment of water quality by manure and other substances in runoff and infiltrating water is a concern, especially where intensive livestock production is carried out. In the US, in a comparison of 32 industries, the livestock industry was found to have a relatively good record of compliance with environmental regulations pursuant to the Clean Water Act and Clean Air Act, but pollution issues from large livestock operations can sometimes be serious where violations occur. Various measures have been suggested by the US Environmental Protection Agency, among others, which can help reduce livestock damage to streamwater quality and riparian environments. Changes in livestock production practices influence the environmental impact of meat production, as illustrated by some beef data. In the US beef production system, practices prevailing in 2007 are estimated to have involved 8.6% less fossil fuel use, 16% less greenhouse gas emissions (estimated as 100-year carbon dioxide equivalents), 12% less withdrawn water use and 33% less land use, per unit mass of beef produced, than in 1977. From 1980 to 2012 in the US, while population increased by 38%, the small ruminant inventory decreased by 42%, the cattle-and-calves inventory decreased by 17%, and methane emissions from livestock decreased by 18%; yet despite the reduction in cattle numbers, US beef production increased over that period. Some impacts of meat-producing livestock may be considered environmentally beneficial. These include waste reduction by conversion of human-inedible crop residues to food, use of livestock as an alternative to herbicides for control of invasive and noxious weeds and other vegetation management, use of animal manure as fertilizer as a substitute for those synthetic fertilizers that require considerable fossil fuel use for manufacture, grazing use for wildlife habitat enhancement, and carbon sequestration in response to grazing practices, among others. Conversely, according to some studies appearing in peer-reviewed journals, the growing demand for meat is contributing to significant biodiversity loss as it is a significant driver of deforestation and habitat destruction. Moreover, the 2019 Global Assessment Report on Biodiversity and Ecosystem Services by IPBES also warns that ever increasing land use for meat production plays a significant role in biodiversity loss. A 2006 Food and Agriculture Organization report, Livestock's Long Shadow, found that around 26% of the planet's terrestrial surface is devoted to livestock grazing. Palm oil Palm oil is a type of vegetable oil, found in oil palm trees, which are native to West and Central Africa. Initially used in foods in developing countries, palm oil is now also used in food, cosmetic and other types of products in other nations as well. Over one-third of vegetable oil consumed globally is palm oil. Habitat loss The consumption of palm oil in food, domestic and cosmetic products all over the world means there is a high demand for it. To meet this, oil palm plantations are created, which means removing natural forests to clear space. This deforestation has taken place in Asia, Latin America and West Africa, with Malaysia and Indonesia holding 90% of global oil palm trees. These forests are home to a wide range of species, including many endangered animals, ranging from birds to rhinos and tigers. Since 2000, 47% of deforestation has been for the purpose of growing oil palm plantations, with around 877,000 acres being affected per year. Impact on biodiversity Natural forests are extremely biodiverse, with a wide range of organisms using them as their habitat. But oil palm plantations are the opposite. Studies have shown that oil palm plantations have less than 1% of the plant diversity seen in natural forests, and 47–90% less mammal diversity. This is not because of the oil palm itself, but rather because the oil palm is the only habitat provided in the plantations. The plantations are therefore known as a monoculture, whereas natural forests contain a wide variety of flora and fauna, making them highly biodiverse. One of the ways palm oil could be made more sustainable (although it is still not the best option) is through agroforestry, whereby the plantations are made up of multiple types of plants used in trade – such as coffee or cocoa. While these are more biodiverse than monoculture plantations, they are still not as effective as natural forests. In addition to this, agroforestry does not bring as many economic benefits to workers, their families and the surrounding areas. Roundtable on Sustainable Palm Oil (RSPO) The RSPO is a non-profit organisation that has developed criteria that its members (of which, as of 2018, there are over 4,000) must follow to produce, source and use sustainable palm oil (Certified Sustainable Palm Oil; CSPO). Currently, 19% of global palm oil is certified by the RSPO as sustainable. The CSPO criteria states that oil palm plantations cannot be grown in the place of forests or other areas with endangered species, fragile ecosystems, or those that facilitate the needs of local communities. It also calls for a reduction in pesticides and fires, along with several rules for ensuring the social wellbeing of workers and the local communities. Ecosystem impacts Environmental degradation Human activity is causing environmental degradation, which is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. As indicated by the I=PAT equation, environmental impact (I) or degradation is caused by the combination of an already very large and increasing human population (P), continually increasing economic growth or per capita affluence (A), and the application of resource-depleting and polluting technology (T). According to a 2021 study published in Frontiers in Forests and Global Change, roughly 3% of the planet's terrestrial surface is ecologically and faunally intact, meaning areas with healthy populations of native animal species and little to no human footprint. Many of these intact ecosystems were in areas inhabited by indigenous peoples. Habitat fragmentation According to a 2018 study in Nature, 87% of the oceans and 77% of land (excluding Antarctica) have been altered by anthropogenic activity, and 23% of the planet's landmass remains as wilderness. Habitat fragmentation is the reduction of large tracts of habitat leading to habitat loss. Habitat fragmentation and loss are considered as being the main cause of the loss of biodiversity and degradation of the ecosystem all over the world. Human actions are greatly responsible for habitat fragmentation, and loss as these actions alter the connectivity and quality of habitats. Understanding the consequences of habitat fragmentation is important for the preservation of biodiversity and enhancing the functioning of the ecosystem. Both agricultural plants and animals depend on pollination for reproduction. Vegetables and fruits are an important diet for human beings and depend on pollination. Whenever there is habitat destruction, pollination is reduced and crop yield as well. Many plants also rely on animals and most especially those that eat fruit for seed dispersal. Therefore, the destruction of habitat for animal severely affects all the plant species that depend on them. Mass extinction Biodiversity generally refers to the variety and variability of life on Earth, and is represented by the number of different species there are on the planet. Since its introduction, Homo sapiens (the human species) has been killing off entire species either directly (such as through hunting) or indirectly (such as by destroying habitats), causing the extinction of species at an alarming rate. Humans are the cause of the current mass extinction, called the Holocene extinction, driving extinctions to 100 to 1000 times the normal background rate. Though most experts agree that human beings have accelerated the rate of species extinction, some scholars have postulated without humans, the biodiversity of the Earth would grow at an exponential rate rather than decline. The Holocene extinction continues, with meat consumption, overfishing, ocean acidification and the amphibian crisis being a few broader examples of an almost universal, cosmopolitan decline in biodiversity. Human overpopulation (and continued population growth) along with overconsumption, especially by the super-affluent, are considered to be the primary drivers of this rapid decline. The 2017 World Scientists' Warning to Humanity stated that, among other things, this sixth extinction event unleashed by humanity could annihilate many current life forms and consign them to extinction by the end of this century. A 2022 scientific review published in Biological Reviews confirms that a biodiversity loss crisis caused by human activity, which the researchers describe as a sixth mass extinction event, is currently underway. A June 2020 study published in PNAS argues that the contemporary extinction crisis "may be the most serious environmental threat to the persistence of civilization, because it is irreversible" and that its acceleration "is certain because of the still fast growth in human numbers and consumption rates." Biodiversity loss It has been estimated that from 1970 to 2016, 68% of the world's wildlife has been destroyed due to human activity. In South America, there is believed to be a 70 percent loss. A May 2018 study published in PNAS found that 83% of wild mammals, 80% of marine mammals, 50% of plants and 15% of fish have been lost since the dawn of human civilization. Currently, livestock make up 60% of the biomass of all mammals on earth, followed by humans (36%) and wild mammals (4%). According to the 2019 global biodiversity assessment by IPBES, human civilization has pushed one million species of plants and animals to the brink of extinction, with many of these projected to vanish over the next few decades. When plant biodiversity declines, the remaining plants face diminishing productivity. Biodiversity loss threatens ecosystem productivity and services such as food, fresh water, raw materials and medicinal resources. A 2019 report that assessed a total of 28,000 plant species concluded that close to half of them were facing a threat of extinction. The failure of noticing and appreciating plants is regarded as "plant blindness", and this is a worrying trend as it puts more plants at the threat of extinction than animals. Our increased farming has come at a higher cost to plant biodiversity as half of the habitable land on Earth is used for agriculture, and this is one of the major reasons behind the plant extinction crisis. Defaunation is the loss of animals from ecological communities. Invasive species Invasive species are defined by the U.S. Department of Agriculture as non-native to the specific ecosystem, and whose presence is likely to harm the health of humans or the animals in said system. Introductions of non-native species into new areas have brought about major and permanent changes to the environment over large areas. Examples include the introduction of Caulerpa taxifolia into the Mediterranean, the introduction of oat species into the California grasslands, and the introduction of privet, kudzu, and purple loosestrife to North America. Rats, cats, and goats have radically altered biodiversity in many islands. Additionally, introductions have resulted in genetic changes to native fauna where interbreeding has taken place, as with buffalo with domestic cattle, and wolves with domestic dogs. Human Introduced Invasive Species Cats Domestic and feral cats globally are particularly notorious for their destruction of native birds and other animal species. This is especially true for Australia, which attributes over two-thirds of mammal extinction to domestic and feral cats, and over 1.5 billion deaths to native animals each year. Because domesticated outside cats are fed by their owners, they can continue to hunt even when prey populations decline and they would otherwise go elsewhere. This is a major problem for places where there is a highly diverse and dense number of lizards, birds, snakes, and mice populating the area. Roaming outdoor cats can also be attributed to the transmission of harmful diseases like rabies and toxoplasmosis to the native wildlife population. Burmese Python Another example of a destructive introduced invasive species is the Burmese Python. Originating from parts of Southeast Asia, the Burmese Python has made the most notable impact in the Southern Florida Everglades of the United States. After a breeding facility breach in 1992 due to flooding and snake owners releasing unwanted pythons back into the wild, the population of the Burmese Python would boom in the warm climate of Florida in the following years. This impact has been felt most significantly at the southernmost regions of the Everglades. A study in 2012 compared native species population counts in Florida from 1997 and found that raccoon populations declined 99.3%, opossums 98.9%, and rabbit/fox populations effectively disappeared Hybrid boars In the 1980s, Canadian pig farmers introduced wild boars from the United Kingdom into their breeding programs, leading to a hybrid with more meat. However, when the pork market collapsed in 2001, many of these hybrids were released into the wild. These hybrids, now numbering around 62,000 are thriving in the Canadian prairies due to their adaptation to harsh winters, with thick fur and long legs, and tusks sharp enough to dig through soil for food. They cause significant agricultural damage and have grown to a point where even substantial culling efforts are insufficient. This issue has escalated to the extent that these boars are starting to migrate into northern US states, raising concerns about potential crop damage and the spread of diseases like African swine flu, which could severely impact the pork industry. Coral reef decline Water pollution Domestic, industrial and agricultural wastewater can be treated in wastewater treatment plants for treatment before being released into aquatic ecosystems. Treated wastewater still contains a range of different chemical and biological contaminants which may influence surrounding ecosystems. Climate change Contemporary climate change is the result of increasing atmospheric greenhouse gas concentrations, which is caused primarily by combustion of fossil fuel (coal, oil, natural gas), and by deforestation, land use changes, and cement production. Such massive alteration of the global carbon cycle has only been possible because of the availability and deployment of advanced technologies, ranging in application from fossil fuel exploration, extraction, distribution, refining, and combustion in power plants and automobile engines and advanced farming practices. Livestock contributes to climate change both through the production of greenhouse gases and through destruction of carbon sinks such as rain-forests. According to the 2006 United Nations/FAO report, 18% of all greenhouse gas emissions found in the atmosphere are due to livestock. The raising of livestock and the land needed to feed them has resulted in the destruction of millions of acres of rainforest and as global demand for meat rises, so too will the demand for land. Ninety-one percent of all rainforest land deforested since 1970 is now used for livestock. Impacts through the atmosphere Acid deposition The air pollutants released from the burning of fossil fuels usually comes back to earth in the form of acid rain. Acid rain is a form of precipitation which has high sulfuric and nitric acids, which can also occur in the form of a fog or snow. Acid rain has numerous ecological impacts on streams, lakes, wetlands and other aquatic environments. It damages forests, robs the soil of its essential nutrients, and releases aluminium in the soil, which creates difficulties in the absorption of water for local plant life. Researchers have discovered that kelp, eelgrass and other aquatic vegetation absorbs carbon dioxide and hence reduces ocean acidity. Scientists, therefore, say that growing these plants could help in mitigating the damaging effects of acidification on marine life. Ozone depletion Disruption of the nitrogen cycle Of particular concern is N2O, which has an average atmospheric lifetime of 114–120 years, and is 300 times more effective than CO2 as a greenhouse gas. NOx produced by industrial processes, automobiles and agricultural fertilization and NH3 emitted from soils (i.e., as an additional byproduct of nitrification) and livestock operations are transported to downwind ecosystems, influencing N cycling and nutrient losses. Six major effects of NOx and NH3 emissions have been identified: decreased atmospheric visibility due to ammonium aerosols (fine particulate matter [PM]) elevated ozone concentrations ozone and PM affects human health (e.g. respiratory diseases, cancer) increases in radiative forcing and global warming decreased agricultural productivity due to ozone deposition ecosystem acidification and eutrophication. Technology impacts The applications of technology often result in unavoidable and unexpected environmental impacts, which according to the I = PAT equation is measured as resource use or pollution generated per unit GDP. Environmental impacts caused by the application of technology are often perceived as unavoidable for several reasons. First, given that the purpose of many technologies is to exploit, control, or otherwise "improve" upon nature for the perceived benefit of humanity while at the same time, the myriad of processes in nature have been optimized and are continually adjusted by evolution, any disturbance of these natural processes by technology is likely to result in negative environmental consequences. Second, the conservation of mass principle and the first law of thermodynamics (i.e., conservation of energy) dictate that whenever material resources or energy are moved around or manipulated by technology, environmental consequences are inescapable. Third, according to the second law of thermodynamics, order can be increased within a system (such as the human economy) only by increasing disorder or entropy outside the system (i.e., the environment). Thus, technologies can create "order" in the human economy (i.e., order as manifested in buildings, factories, transportation networks, communication systems, etc.) only at the expense of increasing "disorder" in the environment. According to several studies, increased entropy is likely to correlate to negative environmental impacts. Mining industry The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes. In some cases, additional forest logging is done in the vicinity of mines to increase the available room for the storage of the created debris and soil. Even though plants need some heavy metals for their growth, excess of these metals is usually toxic to them. Plants that are polluted with heavy metals usually depict reduced growth, yield and performance. Pollution by heavy metals decreases the soil organic matter composition resulting in a decline in soil nutrients which then leads to a decline in the growth of plants or even death. Besides creating environmental damage, the contamination resulting from leakage of chemicals also affect the health of the local population. Mining companies in some countries are required to follow environmental and rehabilitation codes, ensuring the area mined is returned to close to its original state. Some mining methods may have significant environmental and public health effects. Heavy metals usually exhibit toxic effects towards the soil biota, and this is through the affection of the microbial processes and decreases the number as well as activity of soil microorganisms. Low concentration of heavy metals also has high chances of inhibiting the plant's physiological metabolism. Energy industry The environmental impact of energy harvesting and consumption is diverse. In recent years there has been a trend towards the increased commercialization of various renewable energy sources. In the real world, consumption of fossil fuel resources leads to global warming and climate change. However, little change is being made in many parts of the world. If the peak oil theory proves true, more explorations of viable alternative energy sources, could be more friendly to the environment. Rapidly advancing technologies can achieve a transition of energy generation, water and waste management, and food production towards better environmental and energy usage practices using methods of systems ecology and industrial ecology. Biodiesel The environmental impact of biodiesel includes energy use, greenhouse gas emissions and some other kinds of pollution. A joint life cycle analysis by the US Department of Agriculture and the US Department of Energy found that substituting 100% biodiesel for petroleum diesel in buses reduced life cycle consumption of petroleum by 95%. Biodiesel reduced net emissions of carbon dioxide by 78.45%, compared with petroleum diesel. In urban buses, biodiesel reduced particulate emissions 32 percent, carbon monoxide emissions 35 percent, and emissions of sulfur oxides 8%, relative to life cycle emissions associated with use of petroleum diesel. Life cycle emissions of hydrocarbons were 35% higher and emission of various nitrogen oxides (NOx) were 13.5% higher with biodiesel. Life cycle analyses by the Argonne National Laboratory have indicated reduced fossil energy use and reduced greenhouse gas emissions with biodiesel, compared with petroleum diesel use. Biodiesel derived from various vegetable oils (e.g. canola or soybean oil), is readily biodegradable in the environment compared with petroleum diesel. Coal mining and burning The environmental impact of coal mining and -burning is diverse. Legislation passed by the US Congress in 1990 required the United States Environmental Protection Agency (EPA) to issue a plan to alleviate toxic air pollution from coal-fired power plants. After delay and litigation, the EPA now has a court-imposed deadline of 16 March 2011, to issue its report. Surface coal mining has the greatest impact on the environment due to its unique extraction process requiring drilling and blasting, which releases macro amounts of airborne particles into the air. This airborne particulate matter releases harmful toxins into the atmosphere such as ammonia, carbon monoxide, and nitrogen oxides. These toxins then lead to many detrimental health effects such as respiratory illnesses and cardiovascular disease. Although coal is the most widely utilized source of energy around the world, the burning of coal emits poisonous toxins into the air, leading to various health ailments of the skin, blood and lung diseases, and various forms of cancer, while also contributing to global warming by the emission of these toxins into the environment. The technology for mining activity has advanced over the years, leading to an increase in mine waste leading to more pollution problems, according to the Safe Drinking Water Foundation Studies that have been conducted in various countries like India, have proven that coal mining has a detrimental effect on other biotic and abiotic factors including vegetation and soil, leading to a decrease in plant populations in mining sites Electricity generation Nuclear power The environmental impact of nuclear power results from the nuclear fuel cycle processes including mining, processing, transporting and storing fuel and radioactive fuel waste. Released radioisotopes pose a health danger to human populations, animals and plants as radioactive particles enter organisms through various transmission routes. Radiation is a carcinogen and causes numerous effects on living organisms and systems. The environmental impacts of nuclear power plant disasters such as the Chernobyl disaster, the Fukushima Daiichi nuclear disaster and the Three Mile Island accident, among others, persist indefinitely, though several other factors contributed to these events including improper management of fail safe systems and natural disasters putting uncommon stress on the generators. The radioactive decay rate of particles varies greatly, dependent upon the nuclear properties of a particular isotope. Radioactive Plutonium-244 has a half-life of 80.8 million years, which indicates the time duration required for half of a given sample to decay, though very little plutonium-244 is produced in the nuclear fuel cycle and lower half-life materials have lower activity thus giving off less dangerous radiation. Oil shale industry The environmental impact of the oil shale industry includes the consideration of issues such as land use, waste management, water and air pollution caused by the extraction and processing of oil shale. Surface mining of oil shale deposits causes the usual environmental impacts of open-pit mining. In addition, the combustion and thermal processing generate waste material, which must be disposed of, and harmful atmospheric emissions, including carbon dioxide, a major greenhouse gas. Experimental in-situ conversion processes and carbon capture and storage technologies may reduce some of these concerns in future, but may raise others, such as the pollution of groundwater. Petroleum The environmental impact of petroleum is often negative because it is toxic to almost all forms of life. Petroleum, a common word for oil or natural gas, is closely linked to virtually all aspects of present society, especially for transportation and heating for both homes and for commercial activities. Reservoirs The environmental impact of reservoirs is coming under ever increasing scrutiny as the world demand for water and energy increases and the number and size of reservoirs increases. Dams and the reservoirs can be used to supply drinking water, generate hydroelectric power, increasing the water supply for irrigation, provide recreational opportunities and flood control. However, adverse environmental and sociological impacts have also been identified during and after many reservoir constructions. Although the impact varies greatly between different dams and reservoirs, common criticisms include preventing sea-run fish from reaching their historical mating grounds, less access to water downstream, and a smaller catch for fishing communities in the area. Advances in technology have provided solutions to many negative impacts of dams but these advances are often not viewed as worth investing in if not required by law or under the threat of fines. Whether reservoir projects are ultimately beneficial or detrimental—to both the environment and surrounding human populations— has been debated since the 1960s and probably long before that. In 1960 the construction of Llyn Celyn and the flooding of Capel Celyn provoked political uproar which continues to this day. More recently, the construction of Three Gorges Dam and other similar projects throughout Asia, Africa and Latin America have generated considerable environmental and political debate. Wind power Manufacturing Cleaning agents The environmental impact of cleaning agents is diverse. In recent years, measures have been taken to reduce these effects. Nanotechnology Nanotechnology's environmental impact can be split into two aspects: the potential for nanotechnological innovations to help improve the environment, and the possibly novel type of pollution that nanotechnological materials might cause if released into the environment. As nanotechnology is an emerging field, there is great debate regarding to what extent industrial and commercial use of nanomaterials will affect organisms and ecosystems. Paint The environmental impact of paint is diverse. Traditional painting materials and processes can have harmful effects on the environment, including those from the use of lead and other additives. Measures can be taken to reduce environmental impact, including accurately estimating paint quantities so that wastage is minimized, use of paints, coatings, painting accessories and techniques that are environmentally preferred. The United States Environmental Protection Agency guidelines and Green Star ratings are some of the standards that can be applied. Paper Plastics Some scientists suggest that by 2050 there could be more plastic than fish in the oceans. A December 2020 study published in Nature found that human-made materials, or anthropogenic mass, exceeds all living biomass on earth, with plastic alone outweighing the mass of all terrestrial and marine animals combined. Pesticides The environmental impact of pesticides is often greater than what is intended by those who use them. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, including nontarget species, air, water, bottom sediments, and food. Pesticide contaminates land and water when it escapes from production sites and storage tanks, when it runs off from fields, when it is discarded, when it is sprayed aerially, and when it is sprayed into water to kill algae. The amount of pesticide that migrates from the intended application area is influenced by the particular chemical's properties: its propensity for binding to soil, its vapor pressure, its water solubility, and its resistance to being broken down over time. Factors in the soil, such as its texture, its ability to retain water, and the amount of organic matter contained in it, also affect the amount of pesticide that will leave the area. Some pesticides contribute to global warming and the depletion of the ozone layer. Pharmaceuticals and personal care Transport The environmental impact of transport is significant because it is a major user of energy, and burns most of the world's petroleum. This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide, for which transport is the fastest-growing emission sector. By subsector, road transport is the largest contributor to global warming. Environmental regulations in developed countries have reduced the individual vehicles emission; however, this has been offset by an increase in the number of vehicles, and more use of each vehicle. Some pathways to reduce the carbon emissions of road vehicles considerably have been studied. Energy use and emissions vary largely between modes, causing environmentalists to call for a transition from air and road to rail and human-powered transport, and increase transport electrification and energy efficiency. Other environmental impacts of transport systems include traffic congestion and automobile-oriented urban sprawl, which can consume natural habitat and agricultural lands. By reducing transportation emissions globally, it is predicted that there will be significant positive effects on Earth's air quality, acid rain, smog and climate change. The health impact of transport emissions is also of concern. A recent survey of the studies on the effect of traffic emissions on pregnancy outcomes has linked exposure to emissions to adverse effects on gestational duration and possibly also intrauterine growth. Aviation The environmental impact of aviation occurs because aircraft engines emit noise, particulates, and gases which contribute to climate change and global dimming. Despite emission reductions from aircraft engines and more fuel-efficient and less polluting turbofan and turboprop engines, the rapid growth of air travel in recent years contributes to an increase in total pollution attributable to aviation. In the EU, greenhouse gas emissions from aviation increased by 87% between 1990 and 2006. Among other factors leading to this phenomenon are the increasing number of hypermobile travellers and social factors that are making air travel commonplace, such as frequent flyer programs. There is an ongoing debate about possible taxation of air travel and the inclusion of aviation in an emissions trading scheme, with a view to ensuring that the total external costs of aviation are taken into account. Roads The environmental impact of roads includes the local effects of highways (public roads) such as on noise pollution, light pollution, water pollution, habitat destruction/disturbance and local air quality; and the wider effects including climate change from vehicle emissions. The design, construction and management of roads, parking and other related facilities as well as the design and regulation of vehicles can change the impacts to varying degrees. Shipping The environmental impact of shipping includes greenhouse gas emissions and oil pollution. In 2007, carbon dioxide emissions from shipping were estimated at 4 to 5% of the global total, and estimated by the International Maritime Organization (IMO) to rise by up to 72% by 2020 if no action is taken. There is also a potential for introducing invasive species into new areas through shipping, usually by attaching themselves to the ship's hull. The First Intersessional Meeting of the IMO Working Group on Greenhouse Gas Emissions from Ships took place in Oslo, Norway on 23–27 June 2008. It was tasked with developing the technical basis for the reduction mechanisms that may form part of a future IMO regime to control greenhouse gas emissions from international shipping, and a draft of the actual reduction mechanisms themselves, for further consideration by IMO's Marine Environment Protection Committee (MEPC). Military General military spending and military activities have marked environmental effects. The United States military is considered one of the worst polluters in the world, responsible for over 39,000 sites contaminated with hazardous materials. Several studies have also found a strong positive correlation between higher military spending and higher carbon emissions where increased military spending has a larger effect on increasing carbon emissions in the Global North than in the Global South. Military activities also affect land use and are extremely resource-intensive. The military does not solely have negative effects on the environment. There are several examples of militaries aiding in land management, conservation, and greening of an area. Additionally, certain military technologies have proven extremely helpful for conservationists and environmental scientists. As well as the cost to human life and society, there is a significant environmental impact of war. Scorched earth methods during, or after war have been in use for much of recorded history but with modern technology war can cause a far greater devastation on the environment. Unexploded ordnance can render land unusable for further use or make access across it dangerous or fatal. Light pollution Artificial light at night is one of the most obvious physical changes that humans have made to the biosphere, and is the easiest form of pollution to observe from space. The main environmental impacts of artificial light are due to light's use as an information source (rather than an energy source). The hunting efficiency of visual predators generally increases under artificial light, changing predator prey interactions. Artificial light also affects dispersal, orientation, migration, and hormone levels, resulting in disrupted circadian rhythms. Fast fashion Fast fashion has become one of the most successful industries in many capitalist societies with the increase in globalisation. Fast fashion is the cheap mass production of clothing, which is then sold on at very low prices to consumers. Today, the industry is worth £2 trillion. Environmental impacts In terms of carbon dioxide emissions, the fast fashion industry contributes between 4–5 billion tonnes per year, equating to 8–10% of total global emissions. Carbon dioxide is a greenhouse gas, meaning it causes heat to get trapped in the atmosphere, rather than being released into space, raising the Earth's temperature – known as global warming. Alongside greenhouse gas emissions the industry is also responsible for almost 35% of microplastic pollution in the oceans. Scientists have estimated that there are approximately 12–125 trillion tonnes of microplastic particles in the Earth's oceans. These particles are ingested by marine organisms, including fish later eaten by humans. The study states that many of the fibres found are likely to have come from clothing and other textiles, either from washing, or degradation. Textile waste is a huge issue for the environment, with around 2.1 billion tonnes of unsold or faulty clothing being disposed per year. Much of this is taken to landfill, but the majority of materials used to make clothes are not biodegradable, resulting in them breaking down and contaminating soil and water. Fashion, much like most other industries such as agriculture, requires a large volume of water for production. The rate and quantity at which clothing is produced in fast fashion means the industry uses 79 trillion litres of water every year. Water consumption has proven to be very detrimental to the environment and its ecosystems, leading to water depletion and water scarcity. Not only do these affect marine organisms, but also human's food sources, such as crops. The industry is culpable for roughly one-fifth of all industrial water pollution. Society and culture Warnings by the scientific community There are many publications from the scientific community to warn everyone about growing threats to sustainability, in particular threats to "environmental sustainability". The World Scientists' Warning to Humanity in 1992 begins with: "Human beings and the natural world are on a collision course". About 1,700 of the world's leading scientists, including most Nobel Prize laureates in the sciences, signed this warning letter. The letter mentions severe damage to the atmosphere, oceans, ecosystems, soil productivity, and more. It said that if humanity wants to prevent the damage, steps need to be taken: better use of resources, abandonment of fossil fuels, stabilization of human population, elimination of poverty and more. More warning letters were signed in 2017 and 2019 by thousands of scientists from over 150 countries which called again to reduce overconsumption (including eating less meat), reducing fossil fuels use and other resources and so forth.

Shared Socioeconomic Pathways

Shared Socioeconomic Pathways (SSPs) are climate change scenarios of projected socioeconomic global changes up to 2100 as defined in the IPCC Sixth Assessment Report on climate change in 2021. They are used to derive greenhouse gas emissions scenarios with different climate policies. The SSPs provide narratives describing alternative socio-economic developments. These storylines are a qualitative description of logic relating elements of the narratives to each other. In terms of quantitative elements, they provide data accompanying the scenarios on national population, urbanization and GDP (per capita). The SSPs can be quantified with various Integrated Assessment Models (IAMs) to explore possible future pathways both with regards to socioeconomic and climate pathways. The five scenarios are: SSP1: Sustainability ("Taking the Green Road") SSP2: "Middle of the Road" SSP3: Regional Rivalry ("A Rocky Road") SSP4: Inequality ("A Road Divided") SSP5: Fossil-fueled Development ("Taking the Highway") There are also ongoing efforts to downscaling European shared socioeconomic pathways (SSPs) for agricultural and food systems, combined with representative concentration pathways (RCP) to regionally specific, alternative socioeconomic and climate scenarios. Descriptions of the SSPs SSP1: Sustainability (Taking the Green Road) "The world shifts gradually, but pervasively, toward a more sustainable path, emphasizing more inclusive development that respects predicted environmental boundaries. Management of the global commons slowly improves, educational and health investments accelerate the demographic transition, and the emphasis on economic growth shifts toward a broader emphasis on human well-being. Driven by an increasing commitment to achieving development goals, inequality is reduced both across and within countries. Consumption is oriented toward low material growth and lower resource and energy intensity." SSP2: Middle of the road "The world follows a path in which social, economic, and technological trends do not shift markedly from historical patterns. Development and income growth proceeds unevenly, with some countries making relatively good progress while others fall short of expectations. Global and national institutions work toward but make slow progress in achieving sustainable development goals. Environmental systems experience degradation, although there are some improvements and overall the intensity of resource and energy use declines. Global population growth is moderate and levels off in the second half of the century. Income inequality persists or improves only slowly and challenges to reducing vulnerability to societal and environmental changes remain." SSP3: Regional rivalry (A Rocky Road) "A resurgent nationalism, concerns about competitiveness and security, and regional conflicts push countries to increasingly focus on domestic or, at most, regional issues. Policies shift over time to become increasingly oriented toward national and regional security issues. Countries focus on achieving energy and food security goals within their own regions at the expense of broader-based development. Investments in education and technological development decline. Economic development is slow, consumption is material-intensive, and inequalities persist or worsen over time. Population growth is low in industrialized and high in developing countries. A low international priority for addressing environmental concerns leads to strong environmental degradation in some regions." SSP4: Inequality (A Road Divided) "Highly unequal investments in human capital, combined with increasing disparities in economic opportunity and political power, lead to increasing inequalities and stratification both across and within countries. Over time, a gap widens between an internationally-connected society that contributes to knowledge- and capital-intensive sectors of the global economy, and a fragmented collection of lower-income, poorly educated societies that work in a labor intensive, low-tech economy. Social cohesion degrades and conflict and unrest become increasingly common. Technology development is high in the high-tech economy and sectors. The globally connected energy sector diversifies, with investments in both carbon-intensive fuels like coal and unconventional oil, but also low-carbon energy sources. Environmental policies focus on local issues around middle and high income areas." SSP5: Fossil-Fueled Development (Taking the Highway) "This world places increasing faith in competitive markets, innovation and participatory societies to produce rapid technological progress and development of human capital as the path to sustainable development. Global markets are increasingly integrated. There are also strong investments in health, education, and institutions to enhance human and social capital. At the same time, the push for economic and social development is coupled with the exploitation of abundant fossil fuel resources and the adoption of resource and energy intensive lifestyles around the world. All these factors lead to rapid growth of the global economy, while global population peaks and declines in the 21st century. Local environmental problems like air pollution are successfully managed. There is faith in the ability to effectively manage social and ecological systems, including by geo-engineering if necessary." SSP temperature projections from the IPCC Sixth Assessment Report The IPCC Sixth Assessment Report assessed the projected temperature outcomes of a set of five scenarios that are based on the framework of the SSPs. The names of these scenarios consist of the SSP on which they are based (SSP1-SSP5), combined with the expected level of radiative forcing in the year 2100 (1.9 to 8.5 W/m2). This results in scenario names SSPx-y.z as listed below. The role of SSP4 is missing in this table.

Environmental impact of agriculture

The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice. Farming communities that try to reduce environmental impacts through modifying their practices will adopt sustainable agriculture practices. The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia from cattle waste continue to raise concerns over environmental pollution. When evaluating environmental impact, experts use two types of indicators: "means-based", which is based on the farmer's production methods, and "effect-based", which is the impact that farming methods have on the farming system or on emissions to the environment. An example of a means-based indicator would be the quality of groundwater, which is affected by the amount of nitrogen applied to the soil. An indicator reflecting the loss of nitrate to groundwater would be effect-based. The means-based evaluation looks at farmers' practices of agriculture, and the effect-based evaluation considers the actual effects of the agricultural system. For example, the means-based analysis might look at pesticides and fertilization methods that farmers are using, and effect-based analysis would consider how much is being emitted or what the nitrogen content of the soil is. The environmental impact of agriculture involves impacts on a variety of different factors: the soil, water, the air, animal and soil variety, people, plants, and the food itself. Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste. Because of agriculture's importance to global social and environmental systems, the international community has committed to increasing sustainability of food production as part of Sustainable Development Goal 2: “End hunger, achieve food security and improved nutrition and promote sustainable agriculture". The United Nations Environment Programme's 2021 "Making Peace with Nature" report highlighted agriculture as both a driver and an industry under threat from environmental degradation. By agricultural practice Animal agriculture Irrigation Pesticides Plastics By environmental issue Deforestation Deforestation is clearing the Earth's forests on a large scale worldwide and resulting in many land damages. One of the causes of deforestation is clearing land for pasture or crops. According to British environmentalist Norman Myers, 5% of deforestation is due to cattle ranching, 19% due to over-heavy logging, 22% due to the growing sector of palm oil plantations, and 54% due to slash-and-burn farming. Deforestation causes the loss of habitat for millions of species, and is also a driver of climate change. Trees act as a carbon sink: that is, they absorb carbon dioxide, an unwanted greenhouse gas, out of the atmosphere. Removing trees releases carbon dioxide into the atmosphere and leaves behind fewer trees to absorb the increasing amount of carbon dioxide in the air. In this way, deforestation exacerbates climate change. When trees are removed from forests, the soils tend to dry out because there is no longer shade, and there are not enough trees to assist in the water cycle by returning water vapor back to the environment. With no trees, landscapes that were once forests can potentially become barren deserts. The tree's roots also help to hold the soil together, so when they are removed, mudslides can also occur. The removal of trees also causes extreme fluctuations in temperature. In 2000 the United Nations Food and Agriculture Organisation (FAO) found that "the role of population dynamics in a local setting may vary from decisive to negligible," and that deforestation can result from "a combination of population pressure and stagnating economic, social and technological conditions." Genetic engineering Pollutants Soil degradation Soil degradation is the decline in soil quality that can be a result of many factors, especially from agriculture. Soils hold the majority of the world's biodiversity, and healthy soils are essential for food production and adequate water supply. Common attributes of soil degradation can be salting, waterlogging, compaction, pesticide contamination, a decline in soil structure quality, loss of fertility, changes in soil acidity, alkalinity, salinity, and erosion. Soil erosion is the wearing away of topsoil by water, wind, or farming activities. Topsoil is very fertile, which makes it valuable to farmers growing crops. Soil degradation also has a huge impact on biological degradation, which affects the microbial community of the soil and can alter nutrient cycling, pest and disease control, and chemical transformation properties of the soil. Soil erosion Large scale farming can cause large amounts of soil erosion. 25 to 40 percent of eroded soil ends up in water sources. Soil that carries pesticides and fertilizers pollutes the bodies of water it enters. In the United States and Europe especially, large-scale agriculture has grown and small-scale-agriculture has shrunk due to financial arrangements such as contract farming. Bigger farms tend to favour monocultures, overuse water resources, and accelerate deforestation and soil quality decline. A study from 2020 by the International Land Coalition, together with Oxfam and World Inequality Lab, found that 1% of land owners manage 70% of the world's farmland. The highest discrepancy can be found in Latin America, where the poorest 50% own just 1% of the land. Small landowners, as individuals or families, tend to be more cautious in land use compared to large landowners. As of 2020, however, the proportion of small landowners has been decreasing since the 1980s. Currently, the largest share of smallholdings can be found in Asia and Africa. Tillage erosion Waste Plasticulture is the use of plastic mulch in agriculture. Farmers use plastic sheets as mulch to cover 50-70% of the soil and allow them to use drip irrigation systems to have better control over soil nutrients and moisture. Rain is not required in this system, and farms that use plasticulture are built to encourage the fastest runoff of rain. The use of pesticides with plasticulture allows pesticides to be transported easier in the surface runoff towards wetlands or tidal creeks. The runoff from pesticides and chemicals in the plastic can cause serious deformations and death in shellfish as the runoff carries the chemicals toward the oceans. In addition to the increased runoff that results from plasticulture, there is also the problem of the increased amount of waste from the plastic mulch itself. The use of plastic mulch for vegetables, strawberries, and other row and orchard crops exceeds 110 million pounds annually in the United States. Most plastic ends up in the landfill, although there are other disposal options such as disking mulches into the soil, on-site burying, on-site storage, reuse, recycling, and incineration. The incineration and recycling options are complicated by the variety of the types of plastics that are used and by the geographic dispersal of the plastics. Plastics also contain stabilizers and dyes as well as heavy metals, which limits the number of products that can be recycled. Research is continually being conducted on creating biodegradable or photodegradable mulches. While there has been a minor success with this, there is also the problem of how long the plastic takes to degrade, as many biodegradable products take a long time to break down. Issues by region The environmental impact of agriculture can vary depending on the region as well as the type of agriculture production method that is being used. Listed below are some specific environmental issues in various different regions around the world. Hedgerow removal in the United Kingdom. Soil salinisation, especially in Australia. Phosphate mining in Nauru Methane emissions from livestock in New Zealand. See Climate change in New Zealand. Environmentalists attribute the hypoxic zone in the Gulf of Mexico as being encouraged by nitrogen fertilization of the algae bloom. Coupled systems from agricultural trade leading to regional effects from cascading effects and spillover systems. Environmental factor (Socioeconomic Drivers Section) Sustainable agriculture Sustainable agriculture is the idea that agriculture should occur in a way such that we can continue to produce what is necessary without infringing on the ability for future generations to do the same. The exponential population increase in recent decades has increased the practice of agricultural land conversion to meet the demand for food which in turn has increased the effects on the environment. The global population is still increasing and will eventually stabilize, as some critics doubt that food production, due to lower yields from global warming, can support the global population. Agriculture can have negative effects on biodiversity as well. Organic farming is a multifaceted sustainable agriculture set of practices that can have a lower impact on the environment at a small scale. However, in most cases organic farming results in lower yields in terms of production per unit area. Therefore, widespread adoption of organic agriculture will require additional land to be cleared and water resources extracted to meet the same level of production. A European meta-analysis found that organic farms tended to have higher soil organic matter content and lower nutrient losses (nitrogen leaching, nitrous oxide emissions, and ammonia emissions) per unit of field area but higher ammonia emissions, nitrogen leaching and nitrous oxide emissions per product unit. It is believed by many that conventional farming systems cause less rich biodiversity than organic systems. Organic farming has shown to have on average 30% higher species richness than conventional farming. Organic systems on average also have 50% more organisms. This data has some issues because there were several results that showed a negative effect on these things when in an organic farming system. The opposition to organic agriculture believes that these negatives are an issue with the organic farming system. What began as a small scale, environmentally conscious practice has now become just as industrialized as conventional agriculture. This industrialization can lead to the issues shown above such as climate change, and deforestation. Regenerative agriculture Techniques Conservation tillage Conservation tillage is an alternative tillage method for farming which is more sustainable for the soil and surrounding ecosystem. This is done by allowing the residue of the previous harvest's crops to remain in the soil before tilling for the next crop. Conservation tillage has shown to improve many things such as soil moisture retention, and reduce erosion. Some disadvantages are the fact that more expensive equipment is needed for this process, more pesticides will need to be used, and the positive effects take a long time to be visible. The barriers of instantiating a conservation tillage policy are that farmers are reluctant to change their methods, and would protest a more expensive, and time-consuming method of tillage than the conventional one they are used to.

Exploitation of natural resources

The exploitation of natural resources describes using natural resources, often non-renewable or limited, for economic growth or development. Environmental degradation, human insecurity, and social conflict frequently accompany natural resource exploitation. The impacts of the depletion of natural resources include the decline of economic growth in local areas; however, the abundance of natural resources does not always correlate with a country's material prosperity. Many resource-rich countries, especially in the Global South, face distributional conflicts, where local bureaucracies mismanage or disagree on how resources should be used. Foreign industries also contribute to resource exploitation, where raw materials are outsourced from developing countries, with the local communities receiving little profit from the exchange. This is often accompanied by negative effects of economic growth around the affected areas such as inequality and pollution The exploitation of natural resources started to emerge on an industrial scale in the 19th century as the extraction and processing of raw materials (such as in mining, steam power, and machinery) expanded much further than it had in pre-industrial areas. During the 20th century, energy consumption rapidly increased. Today, about 80% of the world's energy consumption is sustained by the extraction of fossil fuels, which consists of oil, coal and natural gas. Another non-renewable resource humans exploit is subsoil minerals, such as precious metals, mainly used to produce industrial commodities. Intensive agriculture is an example of a mode of production that hinders many aspects of the natural environment, for example the degradation of forests in a terrestrial ecosystem and water pollution in an aquatic ecosystem. As the world population rises and economic growth occurs, the depletion of natural resources influenced by the unsustainable extraction of raw materials becomes an increasing concern. The continuous alteration of the environment through water, mineral, and forest exploitation poses increased risks of climate-based displacement and conflict stemming from scarcity, which threaten to perpetuate social inequities. Causes Advancing technology: Increasing technology sophistication enables faster rates of natural resource extraction. For example, in the past, it could take a long time to log a small amount of trees using only saws. Due to better technology, the rates of deforestation have greatly increased. Overconsumption has created a high demand for natural resources, further exacerbating natural resource exploitation Development of new technologies, such as electric vehicles and portable technologies, i.e, Smartphones, also heavily rely on cobalt mining, often leading to loss of green cover and detrimental health impacts for surrounding communities, often in developing countries like the D.R. of Congo where mining occurs. Consumerism: Unsustainable consumption, driven by both population growth and materialistic ideologies, increases the demand for production and, thereby, the extraction of the natural resources needed to supply this demand. For instance, the consumption of fine jewelry leads to increased mining of gold and diamonds. The extraction of precious metals like gold has degradation effects on the environment, such as loss of forestry during construction of the mining facilities, increased exposure to toxic materials, and disturbance of the nearby ecosystem. Management thinking: In relation to the previous point, companies have adopted the idea according to which the rarer the resource, the more it contributes to the company's competitive advantage. When it comes to natural resources, such an idea leads to natural resource exhaustion. A general lack of respect for native land rights leads to increased exploitation of natural resources on and around native land. Consequences of exploitation of resources Natural resources are not limitless, and the following consequences can arise from the careless and excessive consumption of these resources: Deforestation: Removal of trees for use as resources, such as in agriculture or industry, can lead to large-scale destruction of forests. Around 40% of the Earth's original forest cover has been lost in the last 8000 years. Desertification: Human-led changes in land management practices lead to changes in the ecological characteristics of a region. Land mismanagement and climate change can lead to a loss of ecosystem services, such as through degradation of soil. Together, these losses can result in desertification seen in arid and dry areas. Decrease in natural resources: When resources are exploited faster than they can be replenished, it results in an overall decrease in natural resources in an area. Extinction of species: Processes involved in resource exploitation can directly or indirectly lead to the extinction of species. Animals used for resources can be directly hunted, while destruction of environments, such as through harvesting timber, can also cause extinctions. Forced migration Soil erosion Oil depletion Ozone depletion Greenhouse gas increase Water gasification Natural hazard/Natural disaster Metals and minerals depletion. Indigenous groups have limited ways to relate to the environment and survive on traditional food and water sources Economic consequences Natural resources are vital for human survival, however, if their consumption surpasses their natural replenishment rate, the resources can become depleted. According to the United Nations Food and Agriculture Organization, around 33% of the Earth's soils are presently classified as moderately to highly degraded, with projections indicating that more than 90% could face degradation by the year 2050 and thus cause significant economic consequences. With such rate of erosion of fertile soil, agricultural commodity prices tend to increase significantly. The connection between the consumption rate and the supply rate of resources holds significant implications for long-term economic growth, as sustained high consumption rates of certain resources ultimately jeopardize economic sustainability. For instance, in the case of extracting soil minerals, supply rate is exceedingly slow over geological time spans, inevitably leading to a consumption rate surpassing the supply rate. Such a scenario is evidently unsustainable in the long run. To ensure sustainability, the consumption rate must remain equal to or less than the supply rate. There has been an ongoing debate among scholars and researchers on the economic implications of dependence on natural resources. Natural resources yield economic rents that can be allocated towards public welfare initiatives and other projects beneficial to local communities. However, in the long term, uncertainties linked to potentially unstable terms of trade for commodities might lead to decline in public finances and deter investment. For instance, if oil prices decline, it may lead to fiscal unease in significant petroleum-producing countries such as Russia, Qatar, and Saudi Arabia. Resource abundance challenges the progress of political and governance institutions by nurturing a culture of rentierism. For instance, revenues obtained from resources can be used for political manipulation. Additionally, extra capital from resources can dilute government accountability to both citizens and businesses by abandoning taxation completely, which leads to lack of government incentive to support economic growth through innovation. At the same time, citizens may lack the motives to advocate for better governance and transparency. Because of environmental pollution, cities whose economies rely on natural resources face difficulties in attracting technology-driven businesses and skilled labor, posing significant challenges to their economic transformation and advancement. These resource-centric cities face disadvantages in the competition among local governments striving for environmental quality. Analyzing panel data spanning from 2005 to 2017 for 30 coal-mining cities, it's been discovered that environmental regulations offer a new approach to potentially reversing the adverse effects of resource dependence, and thus fueling greener sustainable development in coal-mining regions. Despite the inevitability of environmental contamination associated with resource extraction because of current mining technologies, this pollution delays residents' engagement in agricultural and aqua cultural activities, which are negatively influenced by environmental conditions. As a result, these cities tend to rely heavily on a singular economic development model centered around resource exploitation, making them ill-equipped to address environmental crises effectively. Economic gains from natural resources are mostly beneficial when directed towards initiatives such as job creation, skill enhancement, capacity building, and pursuit of long-term developmental objectives. Thus, reliance on one or more natural resources holds financial risk when aiming for a stable economic growth. Impacts of settler colonialism Multiple scholars have explained how Settler colonialism has had profound influence on the dynamics of resource exploitation throughout history, especially in regions where settler populations have previously asserted dominance over indigenous peoples and their territories. Among these scholars Dina Gilio-Whitaker, an expert in Native American Studies from California State University explains that, “Indigenous peoples fighting for political autonomy from the hegemony of the State are fighting the forces of colonialism while simultaneously fighting capitalism—all aimed at control of land and resources" This encompasses the establishment of permanent settler communities, typically accompanied by the displacement, marginalization, or even extermination of indigenous populations. Settler Colonial exploration is most often driven by the pursuit of land and resources which has historically created the exploitation of natural wealth to fuel economic growth, infrastructure development, and territorial expansion. One of the key way which settler colonialism drives resource exploitation is through the appropriation of indigenous lands and natural resources. Kyle Powys Whyte, an expert in natural resources and the environment highlights how the continued legacy of settler colonialism continues to harm indigenous communities. In his piece “The Dakota Access Pipeline, Environmental Injustice, and US Settler Colonialism” he writes, “as climate change becomes more apparent in its homelands, the shifting plant and animal habitats tied to agriculture, wildlife, and ceremonial species, as well as the loss of territory and resources as a result of US settler colonialism, will make it harder to adjust.” Settler societies often view the land as a commodity to be exploited for economic gain, leading to the establishment of extractive industries such as mining, logging, and agriculture on indigenous territories. This exploitation is facilitated by legal frameworks that prioritize settler property rights over indigenous land tenure systems, resulting in the dispossession and displacement of indigenous communities from their ancestral lands. Moreover, settler colonialism often entails the imposition of Western concepts of land ownership and resource management that marginalize indigenous knowledge and practices, further exacerbating environmental degradation and social injustice. Impacts of industrialization and globalization Industrialization, the large scale growth of industry, has had profound impacts on natural resource exploitation. As societies undergo industrialization, there is an increased demand for raw materials to fuel manufacturing, construction, and energy production. As outlined by Farhan Ahmed, professor of economics and finance, industrialization can bring a myriad of challenges for natural resources. In his piece “The environmental impact of industrialization and foreign direct investment: empirical evidence from Asia-Pacific region” Ahmed writes “In addition to the many benefits of foreign direct investment and industrialization that have affected economic growth, both have significant potential for environmental degradation because most of their activities are related to the production and exploitation of natural resources." This demand often leads to intensified extraction activities, such as mining, logging, and drilling, which can result in extensive habitat destruction, deforestation, and ecosystem degradation. Additionally, industrial processes often generate pollution and waste, further exacerbating environmental impacts and threatening ecosystems and biodiversity. industrialization has been associated with the commodification of natural resources, where resources are valued primarily for their economic potential rather than their intrinsic ecological or cultural value. This commodification mindset often leads to unsustainable exploitation practices, as resources are overexploited for short-term economic gain without consideration for long-term environmental sustainability. Globalization has significantly impacted resource exploitation by reshaping patterns of production, consumption, and trade on a global scale. The interconnectedness of economies and the proliferation of multinational corporations have led to increased competition for access to natural resources, such as minerals, fossil fuels, timber, and agricultural products, in diverse regions around the world. This heightened demand for resources has driven intensified extraction activities, often in environmentally sensitive areas, and has contributed to the overexploitation and depletion of finite resources. Haiying Liu, professor of economics, explains how globalization results in more environmental stress in her piece “Impact of governance and globalization on natural resources volatility”. In this piece she writes, “In addition to natural resources exported from the region, the technical capability required to explore natural resources is also dependent on economic globalization. Environmental pressure increases as a result of globalization.” Globalization has spurred the development of complex supply chains and trade networks that connect resource-rich regions with centers of production and consumption across the globe. While this interconnectedness has fueled economic growth and development in some regions, it has also led to the commodification and commercialization of natural resources, where resources are valued primarily for their economic potential rather than their intrinsic ecological or cultural value. Globalization has contributed to the unequal distribution of benefits and burdens associated with resource exploitation, with marginalized communities often bearing the environmental and social costs of resource extraction while multinational corporations and rich nations reap the profits Effects on local communities Papua New Guinea When a mining company enters a developing country in the global south to extract raw materials, advocating the advantages of the industry's presence and minimizing the potential negative effects gain the cooperation of the local people. Advantageous factors are primarily in economic development establishments, such as health centers, police departments, and schools, that the government may not provide. However, these advantages are not always distributed evenly among local populations, and the income generated from extracting natural resources can result in internal conflict within the developing country. In addition to unequal distribution, the adaption of consumerist values also results in conflict over resources within local communities. Despite being rich in natural resources, the Democratic Republic of Congo is one country in the global south suffering from the effects of the resource curse. Its valuable copper and cobalt mineral deposits make Congo vulnerable to local and international conflict over the distribution of resources. These conflicts, along with the environmental degradation effects of mining, exacerbate high poverty rates, which approximately 64% of the Congolese population live under. Natural resource extraction and climate change are intertwined in Congo, as mining for copper and cobalt creates a biodiversity loss as green covers are cleared for constructing artisanal mines and roadways. Conflict over resources, poverty, and environmental degradation leaves a large number of the Congolese population vulnerable to internal displacement, lacking resources to adapt to climate change. Beyond climate impacts, mineral mining has also been linked with adverse health impacts, such as high levels of cobalt in urine and blood samples in populations located on or near industrial mines. Mining ores pose health risks long after mining has ceased, as wastelands generate toxic metal-rich dust. The injustice perpetrated by unsafe mining ores is not exclusive to the adult and child laborers. Instead, it impacts the whole country as low wages for high-risk mining worsen poverty rates, exacerbating negative social impacts such as conflict, higher crime rates, and child mortality. The effects of the exploitation of natural resources in the local community of a developing country are also exhibited in the impacts from the Ok Tedi Mine. After BHP entered into Papua New Guinea to exploit copper and gold, the economy of the indigenous peoples boomed. Although their quality of life has improved, initially disputes were common among the locals in terms of land rights and who should be getting the benefits from the mining project. The consequences of the Ok Tedi environmental disaster illustrate the potential negative effects from the exploitation of natural resources. The resulting mining pollution includes toxic contamination of the natural water supply for communities along the Ok Tedi River, causing widespread killing of aquatic life. When a mining company ends a project after extracting the raw materials from an area of a developing country, the local people are left to manage with the environmental damage done to their community and the long run sustainability of the economic benefits stimulated by the mining company's presence becomes a concern. Responses and solutions Responses and solutions to natural resource exploitation have emerged across the globe as communities and stakeholders grapple with the environmental, social, and economic impacts of unsustainable practices. These movements often employ a variety of tactics, including protests, legal challenges, boycotts, and direct actions, to challenge destructive practices and promote alternatives that prioritize environmental sustainability, social justice, and community well-being. Additionally, there has been growing recognition of the importance of indigenous knowledge, traditional ecological practices, and community-based approaches in addressing the root causes of resource exploitation and advancing sustainable development goals. Resistance to mining in Peru Resistance to natural resource exploitation in the developing countries is often intertwined with broader social and economic struggles. Many communities facing exploitation are marginalized and economically disadvantaged which exacerbates the unequal power dynamics at play. Resistance movements often demand not only environmental justice but also fair compensation, employment opportunities, and community development initiatives. Solidarity networks, both within countries and internationally, have been crucial in amplifying the voices of affected communities and exerting pressure on governments and corporations to adopt more sustainable and equitable practices. Despite facing significant challenges, these movements continue to inspire hope for a more just and sustainable future in the Global South and beyond. Anti-mining protests in Peru have emerged as a significant expression of resistance against large-scale mining projects that pose environmental and social threats to local communities. One notable instance is the resistance against the Conga mining project in the Cajamarca region. José Manuyama Ahuit, a native Peruvian activist working against local mining, was quoted saying, “The river forms part of our spirit and culture. If the river dies, so does our human dignity, now this river is doomed. The colour of the water is changing, and the same devastation in other mining areas is beginning to be reproduced here in the Nanay. Local communities, including farmers and indigenous groups, have vehemently opposed the project due to concerns of water contamination and depletion. The proposed mining operation, led by multinational corporations, has been met with widespread demonstrations, blockades, and legal challenges. These protests underscore broader issues of environmental protection and indigenous rights, as communities seek to safeguard their lands and livelihoods from the detrimental impacts of resource extraction. In response to the anti-mining protests, Peruvian authorities have often deployed security forces to quell dissent, leading to clashes and instances of violence. These clashes have resulted in injuries and fatalities on both sides, escalating tensions between mining companies, local communities, and the government. Efforts to find a peaceful resolution to the conflict have been disrupted by deep-seated mistrust and differing interests among the stakeholders involved. Resistance in Native American communities Resistance to natural resource exploitation in native communities has been a recurring theme throughout history, as indigenous people  have sought to protect their lands, cultures, and ways of life from the adverse impacts of extractive industries. In many cases, indigenous resistance movements have emerged as powerful forces advocating for environmental justice, indigenous rights, and sovereignty over ancestral territories. These movements often mobilize around issues such as land rights, resource extraction, and environmental protection, employing a variety of tactics, including protests, legal challenges, direct actions, and advocacy campaigns to assert indigenous control over natural resources and resist exploitative practices. The Dakota Access Pipeline resistance, also known as the Standing Rock movement, emerged as a significant indigenous-led protest against the construction of the Dakota Access Pipeline in the United States. The pipeline, proposed by Energy Transfer Partners, was intended to transport crude oil from North Dakota to Illinois, traversing ancestral lands and sacred sites of the Standing Rock Sioux Tribe, as well as posing potential threats to water sources, including the Missouri River, which serves as a vital water supply for the tribe and millions of others downstream. The resistance movement, which began in 2016, brought together indigenous activists, environmentalists, and allies from across the country and around the world in a unified effort to oppose the pipeline's construction. Nick Estes, a scholar of American Indian studies who has followed the Dakota Access Pipeline protests closely, points out that the tactics being used in protest of the Dakota Access Pipeline have been used for generations. In his piece  “Our History is The Future”  he writes, “Our history and long traditions of Indigenous resistance provide possibilities for futures premised on justice. After all, Indigenous resistance is animated by our ancestors' refusal to be forgotten, and it is our resolute refusal to forget our ancestors and our history that animates our visions for liberation. The Dakota Access Pipeline resistance garnered widespread attention and support, drawing thousands of people to the Standing Rock Indian Reservation in North Dakota to stand in solidarity with the Standing Rock Sioux Tribe and protect their lands and water. Among the supporters was activist and performing artists Dallas Goldtooth of the Dakota tribe. Goldtooth highlighted the importance of social media in modern protests saying, “social media allowed immediate direct one-on-one access and kind of this perception of unfiltered access – unfiltered access to what was happening on the ground" The movement was characterized by nonviolent protests, prayer ceremonies, and acts of civil disobedience, as well as legal challenges aimed at halting the pipeline's construction and holding the government and energy companies accountable for violating indigenous rights and environmental regulations. The resistance movement also sparked a broader conversation about indigenous sovereignty, environmental justice, and the impacts of fossil fuel infrastructure on indigenous communities and the environment.

Behavioural sciences

Behavioural science is the branch of science concerned with human behaviour. While the term can technically be applied to the study of behaviour amongst all living organisms, it is nearly always used with reference to humans as the primary target of investigation (though animals may be studied in some instances, e.g. invasive techniques). The behavioural sciences sit in between the conventional natural sciences and social studies in terms of scientific rigor. It encompasses fields such as psychology, neuroscience, linguistics, and economics. Scope The behavioural sciences encompass both natural and social scientific disciplines, including various branches of psychology, neuroscience and biobehavioural sciences, behavioural economics and certain branches of criminology, sociology and political science. This interdisciplinary nature allows behavioural scientists to coordinate findings from psychological experiments, genetics and neuroimaging, self-report studies, interspecies and cross-cultural comparisons, and correlational and longitudinal designs to understand the nature, frequency, mechanisms, causes and consequences of given behaviours. With respect to the applied behavioural science and behavioural insights, the focus is usually narrower, tending to encompass cognitive psychology, social psychology and behavioural economics generally, and invoking other more specific fields (e.g. health psychology) where needed. In applied settings behavioural scientists exploit their knowledge of cognitive biases, heuristics, and peculiarities of how decision-making is affected by various factors to develop behaviour change interventions or develop policies which 'nudge' people to acting more auspiciously (see Applications below). Future and emerging techniques Robila explains how using modern technology to study and understand behavioral patterns on a greater scale, such as artificial intelligence, machine learning, and greater data has a future in brightening up behavioral science assistance/ research. Creating cutting-edge therapies and interventions with immersive technology like virtual reality/ AI would also be beneficial to behavioral science future(s). These concepts are only a hint of the many paths behavioral science may take in the future. Applications Insights from several pure disciplines across behavioural sciences are explored by various applied disciplines and practiced in the context of everyday life and business. Consumer behaviour, for instance, is the study of the decision making process consumers make when purchasing goods or services. It studies the way consumers recognise problems and discover solutions. Behavioural science is applied in this study by examining the patterns consumers make when making purchases, the factors that influenced those decisions, and how to take advantage of these patterns. Organisational behaviour is the application of behavioural science in a business setting. It studies what motivates employees, how to make them work more effectively, what influences this behaviour, and how to use these patterns in order to achieve the company's goals. Managers often use organisational behaviour to better lead their employees. Using insights from psychology and economics, behavioural science can be leveraged to understand how individuals make decisions regarding their health and ultimately reduce disease burden through interventions such as loss aversion, framing, defaults, nudges, and more. Other applied disciplines of behavioural science include operations research and media psychology. Differentiation from social sciences The terms behavioural sciences and social sciences are interconnected fields that both study systematic processes of behaviour, but they differ on their level of scientific analysis for various dimensions of behaviour. Behavioural sciences abstract empirical data to investigate the decision process and communication strategies within and between organisms in a social system. This characteristically involves fields like psychology, social neuroscience, ethology, and cognitive science. In contrast, social sciences provide a perceptive framework to study the processes of a social system through impacts of a social organisation on the structural adjustment of the individual and of groups. They typically include fields like sociology, economics, public health, anthropology, demography, and political science. Many subfields of these disciplines test the boundaries between behavioural and social sciences. For example, political psychology and behavioural economics use behavioural approaches, despite the predominant focus on systemic and institutional factors in the broader fields of political science and economics.

Abiotic component

In biology and ecology, abiotic components or abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Abiotic factors and the phenomena associated with them underpin biology as a whole. They affect a plethora of species, in all forms of environmental conditions, such as marine or terrestrial animals. Humans can make or change abiotic factors in a species' environment. For instance, fertilizers can affect a snail's habitat, or the greenhouse gases which humans utilize can change marine pH levels. Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and reproduction. Resources are distinguished as substances or objects in the environment required by one organism and consumed or otherwise made unavailable for use by other organisms. Component degradation of a substance occurs by chemical or physical processes, e.g. hydrolysis. All non-living components of an ecosystem, such as atmospheric conditions and water resources, are called abiotic components. Factors In biology, abiotic factors can include water, light, radiation, temperature, humidity, atmosphere, acidity, salinity, precipitation, altitude, minerals, tides, rain, dissolved oxygen nutrients, and soil. The macroscopic climate often influences each of the above. Pressure and sound waves may also be considered in the context of marine or sub-terrestrial environments. Abiotic factors in ocean environments also include aerial exposure, substrate, water clarity, solar energy and tides. Consider the differences in the mechanics of C3, C4, and CAM plants in regulating the influx of carbon dioxide to the Calvin-Benson Cycle in relation to their abiotic stressors. C3 plants have no mechanisms to manage photorespiration, whereas C4 and CAM plants utilize a separate PEP carboxylase enzyme to prevent photorespiration, thus increasing the yield of photosynthesis processes in certain high energy environments. Examples Many Archea require very high temperatures, pressures or unusual concentrations of chemical substances such as sulfur; this is due to their specialization into extreme conditions. In addition, fungi have also evolved to survive at the temperature, the humidity, and stability of their environment. For example, there is a significant difference in access in both water and humidity between temperate rain forests and deserts. This difference in water availability causes a diversity in the organisms that survive in these areas. These differences in abiotic components alter the species present both by creating boundaries of what species can survive within the environment, and influencing competition between two species. Abiotic factors such as salinity can give one species a competitive advantage over another, creating pressures that lead to speciation and alteration of a species to and from generalist and specialist competitors.

Sustainability

Sustainability is a social goal for people to co-exist on Earth over a long period of time. Definitions of this term are disputed and have varied with literature, context, and time. Sustainability usually has three dimensions (or pillars): environmental, economic, and social. Many definitions emphasize the environmental dimension. This can include addressing key environmental problems, including climate change and biodiversity loss. The idea of sustainability can guide decisions at the global, national, organizational, and individual levels. A related concept is that of sustainable development, and the terms are often used to mean the same thing. UNESCO distinguishes the two like this: "Sustainability is often thought of as a long-term goal (i.e. a more sustainable world), while sustainable development refers to the many processes and pathways to achieve it." Details around the economic dimension of sustainability are controversial. Scholars have discussed this under the concept of weak and strong sustainability. For example, there will always be tension between the ideas of "welfare and prosperity for all" and environmental conservation, so trade-offs are necessary. It would be desirable to find ways that separate economic growth from harming the environment. This means using fewer resources per unit of output even while growing the economy. This decoupling reduces the environmental impact of economic growth, such as pollution. Doing this is difficult. Some experts say there is no evidence that such a decoupling is happening at the required scale. It is challenging to measure sustainability as the concept is complex, contextual, and dynamic. Indicators have been developed to cover the environment, society, or the economy but there is no fixed definition of sustainability indicators. The metrics are evolving and include indicators, benchmarks and audits. They include sustainability standards and certification systems like Fairtrade and Organic. They also involve indices and accounting systems such as corporate sustainability reporting and Triple Bottom Line accounting. It is necessary to address many barriers to sustainability to achieve a sustainability transition. Some barriers arise from nature and its complexity while others are extrinsic to the concept of sustainability. For example, they can result from the dominant institutional frameworks in countries. Global issues of sustainability are difficult to tackle as they need global solutions. Existing global organizations such as the UN and WTO are seen as inefficient in enforcing current global regulations. One reason for this is the lack of suitable sanctioning mechanisms. Governments are not the only sources of action for sustainability. For example, business groups have tried to integrate ecological concerns with economic activity, seeking sustainable business. Religious leaders have stressed the need for caring for nature and environmental stability. Individuals can also live more sustainably. Some people have criticized the idea of sustainability. One point of criticism is that the concept is vague and only a buzzword. Another is that sustainability might be an impossible goal. Some experts have pointed out that "no country is delivering what its citizens need without transgressing the biophysical planetary boundaries". Definitions Current usage Sustainability is regarded as a "normative concept". This means it is based on what people value or find desirable: "The quest for sustainability involves connecting what is known through scientific study to applications in pursuit of what people want for the future." The 1983 UN Commission on Environment and Development (Brundtland Commission) had a big influence on the use of the term sustainability today. The commission's 1987 Brundtland Report provided a definition of sustainable development. The report, Our Common Future, defines it as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs". The report helped bring sustainability into the mainstream of policy discussions. It also popularized the concept of sustainable development. Some other key concepts to illustrate the meaning of sustainability include: It may be a fuzzy concept but in a positive sense: the goals are more important than the approaches or means applied; It connects with other essential concepts such as resilience, adaptive capacity, and vulnerability. Choices matter: "it is not possible to sustain everything, everywhere, forever"; Scale matters in both space and time, and place matters; Limits exist (see planetary boundaries). In everyday usage, sustainability often focuses on the environmental dimension. Specific definitions Scholars say that a single specific definition of sustainability may never be possible. But the concept is still useful. There have been attempts to define it, for example: "Sustainability can be defined as the capacity to maintain or improve the state and availability of desirable materials or conditions over the long term." "Sustainability [is] the long-term viability of a community, set of social institutions, or societal practice. In general, sustainability is understood as a form of intergenerational ethics in which the environmental and economic actions taken by present persons do not diminish the opportunities of future persons to enjoy similar levels of wealth, utility, or welfare." "Sustainability means meeting our own needs without compromising the ability of future generations to meet their own needs. In addition to natural resources, we also need social and economic resources. Sustainability is not just environmentalism. Embedded in most definitions of sustainability we also find concerns for social equity and economic development." Some definitions focus on the environmental dimension. The Oxford Dictionary of English defines sustainability as: "the property of being environmentally sustainable; the degree to which a process or enterprise is able to be maintained or continued while avoiding the long-term depletion of natural resources". Historical usage The term sustainability is derived from the Latin word sustinere. "To sustain" can mean to maintain, support, uphold, or endure. So sustainability is the ability to continue over a long period of time. In the past, sustainability referred to environmental sustainability. It meant using natural resources so that people in the future could continue to rely on them in the long term. The concept of sustainability, or Nachhaltigkeit in German, goes back to Hans Carl von Carlowitz (1645–1714), and applied to forestry. The term for this now would be sustainable forest management. He used this term to mean the long-term responsible use of a natural resource. In his 1713 work Silvicultura oeconomica, he wrote that "the highest art/science/industriousness [...] will consist in such a conservation and replanting of timber that there can be a continuous, ongoing and sustainable use". The shift in use of "sustainability" from preservation of forests (for future wood production) to broader preservation of environmental resources (to sustain the world for future generations) traces to a 1972 book by Ernst Basler, based on a series of lectures at M.I.T. The idea itself goes back a very long time: Communities have always worried about the capacity of their environment to sustain them in the long term. Many ancient cultures, traditional societies, and indigenous peoples have restricted the use of natural resources. Comparison to sustainable development The terms sustainability and sustainable development are closely related. In fact, they are often used to mean the same thing. Both terms are linked with the "three dimensions of sustainability" concept. One distinction is that sustainability is a general concept, while sustainable development can be a policy or organizing principle. Scholars say sustainability is a broader concept because sustainable development focuses mainly on human well-being. Sustainable development has two linked goals. It aims to meet human development goals. It also aims to enable natural systems to provide the natural resources and ecosystem services needed for economies and society. The concept of sustainable development has come to focus on economic development, social development and environmental protection for future generations. Dimensions Development of three dimensions Scholars usually distinguish three different areas of sustainability. These are the environmental, the social, and the economic. Several terms are in use for this concept. Authors may speak of three pillars, dimensions, components, aspects, perspectives, factors, or goals. All mean the same thing in this context. The three dimensions paradigm has few theoretical foundations. The popular three intersecting circles, or Venn diagram, representing sustainability first appeared in a 1987 article by the economist Edward Barbier. Scholars rarely question the distinction itself. The idea of sustainability with three dimensions is a dominant interpretation in the literature. In the Brundtland Report, the environment and development are inseparable and go together in the search for sustainability. It described sustainable development as a global concept linking environmental and social issues. It added sustainable development is important for both developing countries and industrialized countries: The Rio Declaration from 1992 is seen as "the foundational instrument in the move towards sustainability". It includes specific references to ecosystem integrity. The plan associated with carrying out the Rio Declaration also discusses sustainability in this way. The plan, Agenda 21, talks about economic, social, and environmental dimensions: Agenda 2030 from 2015 also viewed sustainability in this way. It sees the 17 Sustainable Development Goals (SDGs) with their 169 targets as balancing "the three dimensions of sustainable development, the economic, social and environmental". Hierarchy Scholars have discussed how to rank the three dimensions of sustainability. Many publications state that the environmental dimension is the most important. (Planetary integrity or ecological integrity are other terms for the environmental dimension.) Protecting ecological integrity is the core of sustainability according to many experts. If this is the case then its environmental dimension sets limits to economic and social development. The diagram with three nested ellipses is one way of showing the three dimensions of sustainability together with a hierarchy: It gives the environmental dimension a special status. In this diagram, the environment includes society, and society includes economic conditions. Thus it stresses a hierarchy. Another model shows the three dimensions in a similar way: In this SDG wedding cake model, the economy is a smaller subset of the societal system. And the societal system in turn is a smaller subset of the biosphere system. In 2022 an assessment examined the political impacts of the Sustainable Development Goals. The assessment found that the "integrity of the earth's life-support systems" was essential for sustainability. The authors said that "the SDGs fail to recognize that planetary, people and prosperity concerns are all part of one earth system, and that the protection of planetary integrity should not be a means to an end, but an end in itself". The aspect of environmental protection is not an explicit priority for the SDGs. This causes problems as it could encourage countries to give the environment less weight in their developmental plans. The authors state that "sustainability on a planetary scale is only achievable under an overarching Planetary Integrity Goal that recognizes the biophysical limits of the planet". Other frameworks bypass the compartmentalization of sustainability into separate dimensions completely. Environmental sustainability The environmental dimension is central to the overall concept of sustainability. People became more and more aware of environmental pollution in the 1960s and 1970s. This led to discussions on sustainability and sustainable development. This process began in the 1970s with concern for environmental issues. These included natural ecosystems or natural resources and the human environment. It later extended to all systems that support life on Earth, including human society. Reducing these negative impacts on the environment would improve environmental sustainability. Environmental pollution is not a new phenomenon. But it has been only a local or regional concern for most of human history. Awareness of global environmental issues increased in the 20th century. The harmful effects and global spread of pesticides like DDT came under scrutiny in the 1960s. In the 1970s it emerged that chlorofluorocarbons (CFCs) were depleting the ozone layer. This led to the de facto ban of CFCs with the Montreal Protocol in 1987. In the early 20th century, Arrhenius discussed the effect of greenhouse gases on the climate (see also: history of climate change science). Climate change due to human activity became an academic and political topic several decades later. This led to the establishment of the IPCC in 1988 and the UNFCCC in 1992. In 1972, the UN Conference on the Human Environment took place. It was the first UN conference on environmental issues. It stated it was important to protect and improve the human environment.It emphasized the need to protect wildlife and natural habitats: In 2000, the UN launched eight Millennium Development Goals. The aim was for the global community to achieve them by 2015. Goal 7 was to "ensure environmental sustainability". But this goal did not mention the concepts of social or economic sustainability. Specific problems often dominate public discussion of the environmental dimension of sustainability: In the 21st century these problems have included climate change, biodiversity and pollution. Other global problems are loss of ecosystem services, land degradation, environmental impacts of animal agriculture and air and water pollution, including marine plastic pollution and ocean acidification. Many people worry about human impacts on the environment. These include impacts on the atmosphere, land, and water resources. Human activities now have an impact on Earth's geology and ecosystems. This led Paul Crutzen to call the current geological epoch the Anthropocene. Economic sustainability The economic dimension of sustainability is controversial. This is because the term development within sustainable development can be interpreted in different ways. Some may take it to mean only economic development and growth. This can promote an economic system that is bad for the environment. Others focus more on the trade-offs between environmental conservation and achieving welfare goals for basic needs (food, water, health, and shelter). Economic development can indeed reduce hunger or energy poverty. This is especially the case in the least developed countries. That is why Sustainable Development Goal 8 calls for economic growth to drive social progress and well-being. Its first target is for: "at least 7 per cent GDP growth per annum in the least developed countries". However, the challenge is to expand economic activities while reducing their environmental impact. In other words, humanity will have to find ways how societal progress (potentially by economic development) can be reached without excess strain on the environment. The Brundtland report says poverty causes environmental problems. Poverty also results from them. So addressing environmental problems requires understanding the factors behind world poverty and inequality. The report demands a new development path for sustained human progress. It highlights that this is a goal for both developing and industrialized nations. UNEP and UNDP launched the Poverty-Environment Initiative in 2005 which has three goals. These are reducing extreme poverty, greenhouse gas emissions, and net natural asset loss. This guide to structural reform will enable countries to achieve the SDGs. It should also show how to address the trade-offs between ecological footprint and economic development. Social sustainability The social dimension of sustainability is not well defined. One definition states that a society is sustainable in social terms if people do not face structural obstacles in key areas. These key areas are health, influence, competence, impartiality and meaning-making. Some scholars place social issues at the very center of discussions. They suggest that all the domains of sustainability are social. These include ecological, economic, political, and cultural sustainability. These domains all depend on the relationship between the social and the natural. The ecological domain is defined as human embeddedness in the environment. From this perspective, social sustainability encompasses all human activities. It goes beyond the intersection of economics, the environment, and the social. There are many broad strategies for more sustainable social systems. They include improved education and the political empowerment of women. This is especially the case in developing countries. They include greater regard for social justice. This involves equity between rich and poor both within and between countries. And it includes intergenerational equity. Providing more social safety nets to vulnerable populations would contribute to social sustainability. A society with a high degree of social sustainability would lead to livable communities with a good quality of life (being fair, diverse, connected and democratic). Indigenous communities might have a focus on particular aspects of sustainability, for example spiritual aspects, community-based governance and an emphasis on place and locality. Proposed additional dimensions Some experts have proposed further dimensions. These could cover institutional, cultural, political, and technical dimensions. Cultural sustainability Some scholars have argued for a fourth dimension. They say the traditional three dimensions do not reflect the complexity of contemporary society. For example, Agenda 21 for culture and the United Cities and Local Governments argue that sustainable development should include a solid cultural policy. They also advocate for a cultural dimension in all public policies. Another example was the Circles of Sustainability approach, which included cultural sustainability. Interactions between dimensions Environmental and economic dimensions People often debate the relationship between the environmental and economic dimensions of sustainability. In academia, this is discussed under the term weak and strong sustainability. In that model, the weak sustainability concept states that capital made by humans could replace most of the natural capital. Natural capital is a way of describing environmental resources. People may refer to it as nature. An example for this is the use of environmental technologies to reduce pollution. The opposite concept in that model is strong sustainability. This assumes that nature provides functions that technology cannot replace. Thus, strong sustainability acknowledges the need to preserve ecological integrity. The loss of those functions makes it impossible to recover or repair many resources and ecosystem services. Biodiversity, along with pollination and fertile soils, are examples. Others are clean air, clean water, and regulation of climate systems. Weak sustainability has come under criticism. It may be popular with governments and business but does not ensure the preservation of the earth's ecological integrity. This is why the environmental dimension is so important. The World Economic Forum illustrated this in 2020. It found that $44 trillion of economic value generation depends on nature. This value, more than half of the world's GDP, is thus vulnerable to nature loss. Three large economic sectors are highly dependent on nature: construction, agriculture, and food and beverages. Nature loss results from many factors. They include land use change, sea use change and climate change. Other examples are natural resource use, pollution, and invasive alien species. Trade-offs Trade-offs between different dimensions of sustainability are a common topic for debate. Balancing the environmental, social, and economic dimensions of sustainability is difficult. This is because there is often disagreement about the relative importance of each. To resolve this, there is a need to integrate, balance, and reconcile the dimensions. For example, humans can choose to make ecological integrity a priority or to compromise it. Some even argue the Sustainable Development Goals are unrealistic. Their aim of universal human well-being conflicts with the physical limits of Earth and its ecosystems. Measurement tools Environmental impacts of humans There are several methods to measure or describe human impacts on Earth. They include the ecological footprint, ecological debt, carrying capacity, and sustainable yield. The idea of planetary boundaries is that there are limits to the carrying capacity of the Earth. It is important not to cross these thresholds to prevent irreversible harm to the Earth. These planetary boundaries involve several environmental issues. These include climate change and biodiversity loss. They also include types of pollution. These are biogeochemical (nitrogen and phosphorus), ocean acidification, land use, freshwater, ozone depletion, atmospheric aerosols, and chemical pollution. (Since 2015 some experts refer to biodiversity loss as change in biosphere integrity. They refer to chemical pollution as introduction of novel entities.) The IPAT formula measures the environmental impact of humans. It emerged in the 1970s. It states this impact is proportional to human population, affluence and technology. This implies various ways to increase environmental sustainability. One would be human population control. Another would be to reduce consumption and affluence such as energy consumption. Another would be to develop innovative or green technologies such as renewable energy. In other words, there are two broad aims. The first would be to have fewer consumers. The second would be to have less environmental footprint per consumer. The Millennium Ecosystem Assessment from 2005 measured 24 ecosystem services. It concluded that only four have improved over the last 50 years. It found 15 are in serious decline and five are in a precarious condition. Economic costs Experts in environmental economics have calculated the cost of using public natural resources. One project calculated the damage to ecosystems and biodiversity loss. This was the Economics of Ecosystems and Biodiversity project from 2007 to 2011. An entity that creates environmental and social costs often does not pay for them. The market price also does not reflect those costs. In the end, government policy is usually required to resolve this problem. Decision-making can take future costs and benefits into account. The tool for this is the social discount rate. The bigger the concern for future generations, the lower the social discount rate should be. Another approach is to put an economic value on ecosystem services. This allows us to assess environmental damage against perceived short-term welfare benefits. One calculation is that, "for every dollar spent on ecosystem restoration, between three and 75 dollars of economic benefits from ecosystem goods and services can be expected". In recent years, economist Kate Raworth has developed the concept of doughnut economics. This aims to integrate social and environmental sustainability into economic thinking. The social dimension acts as a minimum standard to which a society should aspire. The carrying capacity of the planet acts an outer limit. Barriers There are many reasons why sustainability is so difficult to achieve. These reasons have the name sustainability barriers. Before addressing these barriers it is important to analyze and understand them. Some barriers arise from nature and its complexity ("everything is related"). Others arise from the human condition. One example is the value-action gap. This reflects the fact that people often do not act according to their convictions. Experts describe these barriers as intrinsic to the concept of sustainability. Other barriers are extrinsic to the concept of sustainability. This means it is possible to overcome them. One way would be to put a price tag on the consumption of public goods. Some extrinsic barriers relate to the nature of dominant institutional frameworks. Examples would be where market mechanisms fail for public goods. Existing societies, economies, and cultures encourage increased consumption. There is a structural imperative for growth in competitive market economies. This inhibits necessary societal change. Furthermore, there are several barriers related to the difficulties of implementing sustainability policies. There are trade-offs between the goals of environmental policies and economic development. Environmental goals include nature conservation. Development may focus on poverty reduction. There are also trade-offs between short-term profit and long-term viability. Political pressures generally favor the short term over the long term. So they form a barrier to actions oriented toward improving sustainability. Barriers to sustainability may also reflect current trends. These could include consumerism and short-termism. Transitions Components and characteristics The European Environment Agency defines a sustainability transition as "a fundamental and wide-ranging transformation of a socio-technical system towards a more sustainable configuration that helps alleviate persistent problems such as climate change, pollution, biodiversity loss or resource scarcities." The concept of sustainability transitions is like the concept of energy transitions. One expert argues a sustainability transition must be "supported by a new kind of culture, a new kind of collaboration, [and] a new kind of leadership". It requires a large investment in "new and greener capital goods, while simultaneously shifting capital away from unsustainable systems". It prefers these to unsustainable options. In 2024 an interdisciplinary group of experts including Chip Fletcher, William J. Ripple, Phoebe Barnard, Kamanamaikalani Beamer, Christopher Field, David Karl, David King, Michael E. Mann and Naomi Oreskes published the academic paper "Earth at Risk". They made an extensive review of existing scientific literature, placing the blame for the ecological crisis on "imperialism, extractive capitalism, and a surging population" and proposed a paradigm shift that replaces it with a socio-economic model prioritizing sustainability, resilience, justice, kinship with nature, and communal well-being. They described many ways in which the transition to a sustainable future can be achieved. A sustainability transition requires major change in societies. They must change their fundamental values and organizing principles. These new values would emphasize "the quality of life and material sufficiency, human solidarity and global equity, and affinity with nature and environmental sustainability". A transition may only work if far-reaching lifestyle changes accompany technological advances. Scientists have pointed out that: "Sustainability transitions come about in diverse ways, and all require civil-society pressure and evidence-based advocacy, political leadership, and a solid understanding of policy instruments, markets, and other drivers." There are four possible overlapping processes of transformation. They each have different political dynamics. Technology, markets, government, or citizens can lead these processes. Principles It is possible to divide action principles to make societies more sustainable into four types. These are nature-related, personal, society-related and systems-related principles. Nature-related principles: decarbonize; reduce human environmental impact by efficiency, sufficiency and consistency; be net-positive – build up environmental and societal capital; prefer local, seasonal, plant-based and labor-intensive; polluter-pays principle; precautionary principle; and appreciate and celebrate the beauty of nature. Personal principles: practise contemplation, apply policies with caution, celebrate frugality. Society-related principles: grant the least privileged the greatest support; seek mutual understanding, trust and many wins; strengthen social cohesion and collaboration; engage stakeholders; foster education – share knowledge and collaborate. Systems-related principles: apply systems thinking; foster diversity; make what is relevant to the public more transparent; maintain or increase option diversity. Example steps There are many approaches that people can take to transition to environmental sustainability. These include maintaining ecosystem services, protecting and co-creating common resources, reducing food waste, and promoting dietary shifts towards plant-based foods. Another is reducing population growth by cutting fertility rates. Others are promoting new green technologies, and adopting renewable energy sources while phasing out subsidies to fossil fuels. In 2017 scientists published an update to the 1992 World Scientists' Warning to Humanity. It showed how to move towards environmental sustainability. It proposed steps in three areas: Reduced consumption: reducing food waste, promoting dietary shifts towards mostly plant-based foods. Reducing the number of consumers: further reducing fertility rates and thus population growth. Technology and nature conservation: there are several related approaches. One is to maintain nature's ecosystem services. Another is promote new green technologies. Another is changing energy use. One aspect of this is to adopt renewable energy sources. At the same time it is necessary to end subsidies to energy production through fossil fuels. Agenda 2030 for the Sustainable Development Goals In 2015, the United Nations agreed the Sustainable Development Goals (SDGs). Their official name is Agenda 2030 for the Sustainable Development Goals. The UN described this programme as a very ambitious and transformational vision. It said the SDGs were of unprecedented scope and significance. The UN said: "We are determined to take the bold and transformative steps which are urgently needed to shift the world on to a sustainable and resilient path." The 17 goals and targets lay out transformative steps. For example, the SDGs aim to protect the future of planet Earth. The UN pledged to "protect the planet from degradation, including through sustainable consumption and production, sustainably managing its natural resources and taking urgent action on climate change, so that it can support the needs of the present and future generations". Options for overcoming barriers Issues around economic growth Eco-economic decoupling is an idea to resolve tradeoffs between economic growth and environmental conservation. The idea is to "decouple environmental bads from economic goods as a path towards sustainability". This would mean "using less resources per unit of economic output and reducing the environmental impact of any resources that are used or economic activities that are undertaken". The intensity of pollutants emitted makes it possible to measure pressure on the environment. This in turn makes it possible to measure decoupling. This involves following changes in the emission intensity associated with economic output. Examples of absolute long-term decoupling are rare. But some industrialized countries have decoupled GDP growth from production- and consumption-based emissions. Yet, even in this example, decoupling alone is not enough. It is necessary to accompany it with "sufficiency-oriented strategies and strict enforcement of absolute reduction targets". One study in 2020 found no evidence of necessary decoupling. This was a meta-analysis of 180 scientific studies. It found that there is "no evidence of the kind of decoupling needed for ecological sustainability" and that "in the absence of robust evidence, the goal of decoupling rests partly on faith". Some experts have questioned the possibilities for decoupling and thus the feasibility of green growth. Some have argued that decoupling on its own will not be enough to reduce environmental pressures. They say it would need to include the issue of economic growth. There are several reasons why adequate decoupling is currently not taking place. These are rising energy expenditure, rebound effects, problem shifting, the underestimated impact of services, the limited potential of recycling, insufficient and inappropriate technological change, and cost-shifting. The decoupling of economic growth from environmental deterioration is difficult. This is because the entity that causes environmental and social costs does not generally pay for them. So the market price does not express such costs. For example, the cost of packaging into the price of a product. may factor in the cost of packaging. But it may omit the cost of disposing of that packaging. Economics describes such factors as externalities, in this case a negative externality. Usually, it is up to government action or local governance to deal with externalities. There are various ways to incorporate environmental and social costs and benefits into economic activities. Examples include: taxing the activity (the polluter pays); subsidizing activities with positive effects (rewarding stewardship); and outlawing particular levels of damaging practices (legal limits on pollution). Government action and local governance A textbook on natural resources and environmental economics stated in 2011: "Nobody who has seriously studied the issues believes that the economy's relationship to the natural environment can be left entirely to market forces." This means natural resources will be over-exploited and destroyed in the long run without government action. Elinor Ostrom (winner of the 2009Nobel economics prize) expanded on this. She stated that local governance (or self-governance) can be a third option besides the market or the national government. She studied how people in small, local communities manage shared natural resources. She showed that communities using natural resources can establish rules their for use and maintenance. These are resources such as pastures, fishing waters, and forests. This leads to both economic and ecological sustainability. Successful self-governance needs groups with frequent communication among participants. In this case, groups can manage the usage of common goods without overexploitation. Based on Ostrom's work, some have argued that: "Common-pool resources today are overcultivated because the different agents do not know each other and cannot directly communicate with one another." Global governance Questions of global concern are difficult to tackle. That is because global issues need global solutions. But existing global organizations (UN, WTO, and others) do not have sufficient means. For example, they lack sanctioning mechanisms to enforce existing global regulations. Some institutions do not enjoy universal acceptance. An example is the International Criminal Court. Their agendas are not aligned (for example UNEP, UNDP, and WTO) And some accuse them of nepotism and mismanagement.  Multilateral international agreements, treaties, and intergovernmental organizations (IGOs) face further challenges. These result in barriers to sustainability. Often these arrangements rely on voluntary commitments. An example is Nationally Determined Contributions for climate action. There can be a lack of enforcement of existing national or international regulation. And there can be gaps in regulation for international actors such as multi-national enterprises.Critics of some global organizations say they lack legitimacy and democracy. Institutions facing such criticism include the WTO, IMF, World Bank, UNFCCC, G7, G8 and OECD. Responses by nongovernmental stakeholders Businesses Sustainable business practices integrate ecological concerns with social and economic ones. One accounting framework for this approach uses the phrase "people, planet, and profit". The name of this approach is the triple bottom line. The circular economy is a related concept. Its goal is to decouple environmental pressure from economic growth. Growing attention towards sustainability has led to the formation of many organizations. These include the Sustainability Consortium of the Society for Organizational Learning, the Sustainable Business Institute, and the World Business Council for Sustainable Development. Supply chain sustainability looks at the environmental and human impacts of products in the supply chain. It considers how they move from raw materials sourcing to production, storage, and delivery, and every transportation link on the way. Religious communities Religious leaders have stressed the importance of caring for nature and environmental sustainability. In 2015 over 150 leaders from various faiths issued a joint statement to the UN Climate Summit in Paris 2015. They reiterated a statement made in the Interfaith Summit in New York in 2014:As representatives from different faith and religious traditions, we stand together to express deep concern for the consequences of climate change on the earth and its people, all entrusted, as our faiths reveal, to our common care. Climate change is indeed a threat to life, a precious gift we have received and that we need to care for. Individuals Individuals can also live in a more sustainable way. They can change their lifestyles, practise ethical consumerism, and embrace frugality. These sustainable living approaches can also make cities more sustainable. They do this by altering the built environment. Such approaches include sustainable transport, sustainable architecture, and zero emission housing. Research can identify the main issues to focus on. These include flying, meat and dairy products, car driving, and household sufficiency. Research can show how to create cultures of sufficiency, care, solidarity, and simplicity. Some young people are using activism, litigation, and on-the-ground efforts to advance sustainability. This is particularly the case in the area of climate action. Assessments and reactions Impossible to reach Scholars have criticized the concepts of sustainability and sustainable development from different angles. One was Dennis Meadows, one of the authors of the first report to the Club of Rome, called "The Limits to Growth". He argued many people deceive themselves by using the Brundtland definition of sustainability. This is because the needs of the present generation are actually not met today. Instead, economic activities to meet present needs will shrink the options of future generations. Another criticism is that the paradigm of sustainability is no longer suitable as a guide for transformation. This is because societies are "socially and ecologically self-destructive consumer societies". Some scholars have even proclaimed the end of the concept of sustainability. This is because humans now have a significant impact on Earth's climate system and ecosystems. It might become impossible to pursue sustainability because of these complex, radical, and dynamic issues. Others have called sustainability a utopian ideal: "We need to keep sustainability as an ideal; an ideal which we might never reach, which might be utopian, but still a necessary one." Vagueness The term is often hijacked and thus can lose its meaning. People use it for all sorts of things, such as saving the planet to recycling your rubbish. A specific definition may never be possible. This is because sustainability is a concept that provides a normative structure. That describes what human society regards as good or desirable. But some argue that while sustainability is vague and contested it is not meaningless. Although lacking in a singular definition, this concept is still useful. Scholars have argued that its fuzziness can actually be liberating. This is because it means that "the basic goal of sustainability (maintaining or improving desirable conditions [...]) can be pursued with more flexibility". Confusion and greenwashing Sustainability has a reputation as a buzzword. People may use the terms sustainability and sustainable development in ways that are different to how they are usually understood. This can result in confusion and mistrust. So a clear explanation of how the terms are being used in a particular situation is important. Greenwashing is a practice of deceptive marketing. It is when a company or organization provides misleading information about the sustainability of a product, policy, or other activity. Investors are wary of this issue as it exposes them to risk. The reliability of eco-labels is also doubtful in some cases. Ecolabelling is a voluntary method of environmental performance certification and labelling for food and consumer products. The most credible eco-labels are those developed with close participation from all relevant stakeholders.

Sustainable consumption

Sustainable consumption (sometimes abbreviated to "SC") is the use of products and services in ways that minimizes impacts on the environment. Sustainable consumption can be undertaken in such a way that needs are met for present-day humans and also for future generations. Sustainable consumption is often paralleled with sustainable production; consumption refers to use and disposal (or recycling) not just by individuals and households, but also by governments, businesses, and other organizations. Sustainable consumption is closely related to sustainable production and sustainable lifestyles. "A sustainable lifestyle minimizes ecological impacts while enabling a flourishing life for individuals, households, communities, and beyond. It is the product of individual and collective decisions about aspirations and about satisfying needs and adopting practices, which are in turn conditioned, facilitated, and constrained by societal norms, political institutions, public policies, infrastructures, markets, and culture." The United Nations includes analyses of efficiency, infrastructure, and waste, as well as access to basic services, green and decent jobs, and a better quality of life for all within the concept of sustainable consumption. Sustainable consumption shares a number of common features and is closely linked to sustainable production and sustainable development. Sustainable consumption, as part of sustainable development, is part of the worldwide struggle against sustainability challenges such as climate change, resource depletion, famines, and environmental pollution. Sustainable development as well as sustainable consumption rely on certain premises such as: Effective use of resources, and minimization of waste and pollution Use of renewable resources within their capacity for renewal The reuse and upcycling of product life-cycles so that consumer items are utilized to maximum potential Intergenerational and intragenerational equity Goal 12 of the Sustainable Development Goals seeks to "ensure sustainable consumption and production patterns". Consumption shifting Studies found that systemic change for "decarbonization" of humanity's economic structures or root-cause system changes above politics are required for a substantial impact on global warming. Such changes may result in more sustainable lifestyles, along with associated products, services and expenditures, being structurally supported and becoming sufficiently prevalent and effective in terms of collective greenhouse gas emission reductions. Nevertheless, ethical consumerism usually only refers to individual choices, and not the consumption behavior and/or import and consumption policies by the decision-making of nation-states. These have however been compared for road vehicles, emissions (albeit without considering emissions embedded in imports) and meat consumption per capita as well as by overconsumption. Life-cycle assessments could assess the comparative sustainability and overall environmental impacts of products – including (but not limited to): "raw materials, extraction, processing and transport; manufacturing; delivery and installation; customer use; and end of life (such as disposal or recycling)". Sustainable food consumption The environmental impacts of meat production (and dairy) are large: raising animals for human consumption accounts for approximately 40% of the total amount of agricultural output in industrialized countries. Grazing occupies 26% of the Earth's ice-free terrestrial surface, and feed crop production uses about one third of all arable land. A global food emissions database shows that food systems are responsible for one third of the global anthropogenic GHG emissions. Moreover, there can be competition for resources, such as land, between growing crops for human consumption and growing crops for animals, also referred to as "food vs. feed" (see also: food security). Therefore, sustainable consumption also includes food consumption – shifting to more sustainable diets. Novel foods such as under-development cultured meat and dairy, existing small-scale microbial foods and ground-up insects (see also: pet food and animal feed) are shown to have the potential to reduce environmental impacts by over 80% in a study. Many studies such as a 2019 IPCC report and a 2022 review about meat and sustainability of food systems, animal welfare, and healthy nutrition concluded that meat consumption has to be reduced substantially for sustainable consumption. The review names broad potential measures such as "restrictions or fiscal mechanisms". In , science advisors in the European Commission's Scientific Advice Mechanism came to the identical conclusion, finding that "our diets need to shift towards more plant-based ingredients, rich in vegetables, fruits, wholegrains and pulses. Our diets should be limited in red meat, processed meat, salt, added sugar, and high-fat animal products, while fish and seafood should be sourced from sustainably managed stocks". A considerable proportion of consumers of food produced by the food system may be non-livestock animals such as pet-dogs: the global dog population is estimated to be 900 million, of which around 20% are regarded as owned pets. Sustainable consumption may also involve their feed. Beyond reduction of meat consumption, the composition of livestock feed and fish feed may also be subject of sustainable consumption shifts. Product labels The app CodeCheck gives versed smartphone users some capability to scan ingredients in food, drinks and cosmetics for filtering out some of the products that are legal but nevertheless unhealthy or unsustainable from their consumption/purchases. A similar "personal shopping assistant" has been investigated in a study. Studies indicated a low level of use of sustainability labels on food. Moreover, existing labels have been intensely criticized for invalidity or unreliability, often amounting to greenwashing or being ineffective. In one study, individuals were given a set budget, "which could be spent once a week on a wide range of food and drink products", then data "on each item's carbon footprint was clearly presented, and individuals could view the [unlimited] carbon footprint of their supermarket basket on their shopping bill." The processes of consumption Not only selection, quantity and quality of consumed products may be of relevance to sustainable consumption, the process of consumption, including how selected products are distributed or gathered could be considered a component of it as well: for instance, ordering from a local store online could substantially reduce emissions (in terms of transportation emissions and when not considering which options are available). Bundling items could reduce carbon emissions of deliveries and carbon footprints of in-person shopping-trips can be eliminated e.g. by biking to the shop instead of driving. Product information transparency and trade control If information is linked to products e.g. via a digital product passport, along with proper architecture and governance for data sharing and data protection, it could help achieve climate neutrality and foster dematerialization. In the EU, a Digital Product Passport is being developed. When there is an increase in greenhouse gas emissions in one country as a result of an emissions reduction by a second country with a strict climate policy this is referred to as carbon leakage. In the EU, the proposed Carbon Border Adjustment Mechanism could help mitigate this problem, and possibly increase the capacity to account for imported pollution/harm/death-footprints. Footprints of nondomestic production are significant: for instance, a study concluded that PM2.5 air pollution induced by the contemporary free trade and consumption by the G20 nations causes two million premature deaths annually, suggesting that the average lifetime consumption of about ~28 people in these countries causes at least one premature death (average age ~67) while developing countries "cannot be expected" to implement or be able to implement countermeasures without external support or internationally coordinated efforts. Transparency of supply chains is important for global goals such as ending net-deforestation. Policy-options for reducing imported deforestation also include "Lower/raise import tariffs for sustainably/unsustainably produced commodities" and "Regulate imports, e.g., through quotas, bans, or preferential access agreements". However, several theories of change of policy options rely on (true / reliable) information being available/provided to "shift demand—both intermediate and final—either away from imported [forest-risk commodities (FRC)] completely, e.g., through diet shifts (IC1), or to sustainably produced FRCs, e.g., through voluntary or mandatory supply-chain transparency (IS1, RS2)." As of 2021, one approach under development is binary "labelling" of investments as "green" according to an EU governmental body-created "taxonomy" for voluntarily financial investment redirection/guidance based on this categorization. The company Dayrize is one organization that attempts to accurately assess environmental and social impacts of consumer products. Reliable evaluations and categorizations of products may enable measures such as policy-combinations that include transparent criteria-based eco-tariffs, bans (import control), support of selected production and subsidies which shifts, rather than mainly reduces, consumption. International sanctions during the 2022 Russian invasion of Ukraine included restrictions on Russian fossil fuel imports while supporting alternatives, albeit these sanctions were not based on environment-related qualitative criteria of the products. Fairness and income/spending freedoms The bottom half of the population is directly responsible for less than 20% of energy footprints and consume less than the top 5% in terms of trade-corrected energy. High-income individuals usually have higher energy footprints as they disproportionally use their larger financial resourceswhich they can usually spend freely in their entirety for any purpose as long as the end user purchase is legalfor energy-intensive goods. In particular, the largest disproportionality was identified to be in the domain of transport, where e.g. the top 10% consume 56% of vehicle fuel and conduct 70% of vehicle purchases. Techniques and approaches Choice editing refers to the active process of controlling or limiting the choices available to consumers. Personal Carbon Allowances (PCAs) refers to technology-based schemes to ration GHG emissions. Degrowth Degrowth refers to economic paradigms that address the need to reduce global consumption and production whereby metrics and mechanisms like GDP are replaced by more reality-attached measures such as of health, social and environmental well-being and more needs-based structures. Broadly, degrowth would or does aim to address overconsumption "by addressing real need, reducing wants, ensuring greater distributive equality and ultimately by suppressing production", or "downscaling of production and consumption that increases human wellbeing and enhances [i.e. "grows"] ecological conditions and equity on the planet". A common denominator of degrowth is a decline in the metric GDP. More concrete degrowth proposals are diverse, dispersed throughout the growing body of literature and include: "reducing and redistributing income alone" along with GHG-pricing and wealth redistribution into a global food systems transformation One tool that could possibly be used in large-scale policies is an app that "will guide users to prioritize reduction in high-footprint categories". Another broad proposal suggests that "different roles of labour, work, and action should be acknowledged and scrutinized in detail" which could prompt or be necessary for an "organization of an alternative society" (see also: green job, life-cycle assessment, certification and job evaluation) Consumption such as "domestic water consumption" could be [made to be] considered as a collectively ordered activity especially when such data and contextual education is available the respective collective. Demonetized activities [as well as currently financially unrewarded and unprofitable activities] are important for degrowth. Degrowth also emphasizes the need to 'degrow' various sectors of the economy without a negative connotation usually associated with such measures such as at least temporary job-loss. If no immediate retraining occurs, leisure time may increase at least temporarily. There are some suggestions that in general, increases in leisure time do not per se translate to increased sustainability – in particular that some time saved did not decrease total distance of car travel. Degrowth-related economic concepts A study suggests that the concepts of sharing economy and circular economy on their own, while useful as broad components, are insufficient and ineffective. Economic concepts by which scholarly literature approaches problems such as overconsumption, using this terminology to characterize broad, typically conceptual-stage, solution-proposals include: Doughnut economy (see also: planetary boundaries) Community economy and commons (see also: Commons#Economic theories and Gemeinwohl-Ökonomie) Strong and weak sustainable consumption Some writers make a distinction between "strong" and "weak" sustainability. Strong sustainable consumption refers to participating in viable environmental activities, such as consuming renewable and efficient goods and services (such as electric locomotive, cycling, renewable energy). Strong sustainable consumption also refers to an urgency to reduce individual living space and consumption rate. Weak sustainable consumption is the failure to adhere to strong sustainable consumption. In other words, consumption of highly pollutant activities, such as frequent car use and consumption of non-biodegradable goods (such as plastic items, metals, and mixed fabrics). In 1992, the United Nations Conference on Environment and Development (UNCED), also referred to as the Earth Summit, recognized sustainable consumption as a concept. It also recognized the difference between strong and weak sustainable consumption but set efforts away from strong sustainable consumption. The 1992 Earth Summit found that sustainable consumption rather than sustainable development was . Currently, strong sustainable consumption is only present in of discussion and research. International government organizations’ (IGOs) prerogatives have kept away from strong sustainable consumption. To avoid scrutiny, IGOs have deemed their influences as limited, often aligning its interests with consumer wants and needs. In doing so, they advocate for minimal eco-efficient improvements, resulting in government skepticism and minimal commitments to strong sustainable consumption efforts. In order to achieve sustainable consumption, two developments have to take place: an increase in the efficiency of consumption, and a change in consumption patterns and reductions in consumption levels in industrialized countries and rich social classes in developing countries which have a large ecological footprint and set an example for increasing middle classes in developing countries. The first prerequisite is not sufficient on its own and qualifies as weak sustainable consumption. Technological improvements and eco-efficiency support a reduction in resource consumption. Once this aim has been met, the second prerequisite, the change in patterns and reduction of levels of consumption is indispensable. Strong sustainable consumption approaches also pay attention to the social dimension of well-being and assess the need for changes based on a risk-averse perspective. In order to achieve strong sustainable consumption, changes in infrastructures as well as the choices customers have are required. In the political arena, weak sustainable consumption is more discussed. The so-called attitude-behaviour or values-action gap describes an obstacle to changes in individual customer behavior. Many consumers are aware of the importance of their consumption choices and care about environmental issues, however most do not translate their concerns into their consumption patterns. This is because the purchase decision process is complicated and relies on e.g. social, political, and psychological factors. Young et al. identified a lack of time for research, high prices, a lack of information, and the cognitive effort needed as the main barriers when it comes to green consumption choices. Historical related behaviors In the early twentieth century, especially during the interwar period, families turned to sustainable consumption. When unemployment began to stretch resources, American working-class families increasingly became dependent on secondhand goods, such as clothing, tools, and furniture. Used items offered entry into consumer culture, and they also provided investment value and enhancements to wage-earning capabilities. The Great Depression saw increases in the number of families forced to turn to cast-off clothing. When wages became desperate, employers offered clothing replacements as a substitute for earnings. In response, fashion trends as high-end clothing became a luxury. During the rapid expansion of post-war suburbia, families turned to new levels of mass consumption. Following the conference of 1956, plastic corporations were quick to enter the mass consumption market of post-war America. During this period companies like Dixie began to replace reusable products with disposable containers (plastic items and metals). Unaware of how to dispose of containers, consumers began to throw waste across public spaces and national parks. Following a Vermont State Legislature ban on disposable glass products, plastic corporations banded together to form the Keep America Beautiful organization in order to encourage individual actions and discourage regulation. The organization teamed with schools and government agencies to spread the anti-litter message. Running public service announcements like "Susan Spotless," the organization encouraged consumers to dispose waste in designated areas. Culture shifts Ecological awareness There is a growing recognition that human well-being is interwoven with the natural environment, as well as an interest to change human activities that cause environmental harm. This is evident in the United Nations Paris Agreement goal of maintaining average global warming to optimistically 1.5 °C, and at least below a threshold of 2.0 °C. Western culture tends to celebrate consumer sovereignty and free market solutions to political economy problems. Yet climate change, and the associated tragedy of the global atmospheric commons, represent a large market failure. There are at least three options for achieving cultural shifts and greater ecological awareness. Private solutions labeled as Corporate Social Responsibility (CSR) strive to incorporate sustainability concerns into market supply and demand forces by increasing the transparency of productive processes, as well as awareness of ecological footprints of consumption. Public solutions apply regulatory frameworks such as the cap and trade system to reduce greenhouse gas emissions. An alternative approach adopts polycentric governance strategies across governmental institutions and non-governmental organizations to achieve greater citizen engagement and self-governance systems. Increasing levels of sustainable consumption to contribute to United Nations Sustainable Development Goal 12 will likely require supportive educational resources. Surveys and trends Surveys ranking consumer values such as environmental, social, and sustainability, showed sustainable consumption values to be particularly low. Surveys on environmental awareness saw an increase in perceived “eco-friendly” behavior. When tasked to reduce energy consumption, empirical research found that individuals are only willing to make minimal sacrifices and fail to reach strong sustainable consumption requirements. IGOs are not motivated to adopt sustainable policy decisions, since consumer demands may not meet the requirements of sustainable consumption. Ethnographic research across Europe concluded that post-Financial crisis of 2007–2008 Ireland saw an increase in secondhand shopping and communal gardening. Following a series of financial scandals, Anti-Austerity became a cultural movement. Irish consumer confidence fell, sparking a cultural shift in second-hand markets and charities, stressing sustainability and drawing on . Sustainable Development Goals The Sustainable Development Goals were established by the United Nations in 2015. SDG 12 is meant to "ensure sustainable consumption and production patterns". Specifically, targets 12.1 and 12.A of SDG 12 aim to implement frameworks and support developing countries in order to "move towards more sustainable patterns of consumption and production". Notable conferences and programs 1992—At the United Nations Conference on Environment and Development (UNCED) the concept of sustainable consumption was established in chapter 4 of the Agenda 21. 1995—Sustainable consumption was requested to be incorporated by UN Economic and Social Council (ECOSOC) into the UN Guidelines on Consumer Protection. 1997—A major report on SC was produced by the OECD. 1998—United Nations Environment Program (UNEP) started a SC program and SC is discussed in the Human Development Report of the UN Development Program (UNDP). 2002—A ten-year program on sustainable consumption and production (SCP) was created in the Plan of Implementation at the World Summit on Sustainable Development (WSSD) in Johannesburg. 2003—The "Marrakesh Process" was developed by co-ordination of a series of meetings and other "multi-stakeholder" processes by UNEP and UNDESA following the WSSD. 2018—Third International Conference of the Sustainable Consumption Research and Action Initiative (SCORAI) in collaboration with the Copenhagen Business School. 2022–Bologna, Italy conducts the first or one of the first trials of rewards for sustainable behavior that is not implemented via product prices or subsidy-like financial mechanisms in the EU: with a "Smart Citizen Wallet", described as a supermarket points-like system, citizens will have benefits if they for example use public transport and manage energy well.

Sustainable agriculture

Sustainable agriculture is farming in sustainable ways meeting society's present food and textile needs, without compromising the ability for current or future generations to meet their needs. It can be based on an understanding of ecosystem services. There are many methods to increase the sustainability of agriculture. When developing agriculture within sustainable food systems, it is important to develop flexible business processes and farming practices. Agriculture has an enormous environmental footprint, playing a significant role in causing climate change (food systems are responsible for one third of the anthropogenic greenhouse gas emissions), water scarcity, water pollution, land degradation, deforestation and other processes; it is simultaneously causing environmental changes and being impacted by these changes. Sustainable agriculture consists of environment friendly methods of farming that allow the production of crops or livestock without causing damage to human or natural systems. It involves preventing adverse effects on soil, water, biodiversity, and surrounding or downstream resources, as well as to those working or living on the farm or in neighboring areas. Elements of sustainable agriculture can include permaculture, agroforestry, mixed farming, multiple cropping, and crop rotation. Developing sustainable food systems contributes to the sustainability of the human population. For example, one of the best ways to mitigate climate change is to create sustainable food systems based on sustainable agriculture. Sustainable agriculture provides a potential solution to enable agricultural systems to feed a growing population within the changing environmental conditions. Besides sustainable farming practices, dietary shifts to sustainable diets are an intertwined way to substantially reduce environmental impacts. Numerous sustainability standards and certification systems exist, including organic certification, Rainforest Alliance, Fair Trade, UTZ Certified, GlobalGAP, Bird Friendly, and the Common Code for the Coffee Community (4C). Definition The term "sustainable agriculture" was defined in 1977 by the USDA as an integrated system of plant and animal production practices having a site-specific application that will, over the long term: satisfy human food and fiber needs enhance environmental quality and the natural resource base upon which the agriculture economy depends make the most efficient use of nonrenewable resources and on-farm resources and integrate, where appropriate, natural biological cycles and controls sustain the economic viability of farm operations enhance the quality of life for farmers and society as a whole. Yet the idea of having a sustainable relationship with the land has been prevalent in indigenous communities for centuries before the term was formally added to the lexicon. Aims A common consensus is that sustainable farming is the most realistic way to feed growing populations. In order to successfully feed the population of the planet, farming practices must consider future costs–to both the environment and the communities they fuel.  The risk of not being able to provide enough resources for everyone led to the adoption of technology within the sustainability field to increase farm productivity. The ideal end result of this advancement is the ability to feed ever-growing populations across the world. The growing popularity of sustainable agriculture is connected to the wide-reaching fear that the planet's carrying capacity (or planetary boundaries), in terms of the ability to feed humanity, has been reached or even exceeded. Key principles There are several key principles associated with sustainability in agriculture: The incorporation of biological and ecological processes such as nutrient cycling, soil regeneration, and nitrogen fixation into agricultural and food production practices. Using decreased amounts of non-renewable and unsustainable inputs, particularly environmentally harmful ones. Using the expertise of farmers to both productively work the land as well as to promote the self-reliance and self-sufficiency of farmers. Solving agricultural and natural resource problems through the cooperation and collaboration of people with different skills. The problems tackled include pest management and irrigation. It "considers long-term as well as short-term economics because sustainability is readily defined as forever, that is, agricultural environments that are designed to promote endless regeneration". It balances the need for resource conservation with the needs of farmers pursuing their livelihood. It is considered to be reconciliation ecology, accommodating biodiversity within human landscapes. Oftentimes, the execution of sustainable practices within farming comes through the adoption of technology and environmentally-focused appropriate technology. Environmental factors Practices that can cause long-term damage to soil include excessive tilling of the soil (leading to erosion) and irrigation without adequate drainage (leading to salinization). The most important factors for a farming site are climate, soil, nutrients and water resources. Of the four, water and soil conservation are the most amenable to human intervention. When farmers grow and harvest crops, they remove some nutrients from the soil. Without replenishment, the land suffers from nutrient depletion and becomes either unusable or suffers from reduced yields. Sustainable agriculture depends on replenishing the soil while minimizing the use or need of non-renewable resources, such as natural gas or mineral ores. A farm that can "produce perpetually", yet has negative effects on environmental quality elsewhere is not sustainable agriculture. An example of a case in which a global view may be warranted is the application of fertilizer or manure, which can improve the productivity of a farm but can pollute nearby rivers and coastal waters (eutrophication). The other extreme can also be undesirable, as the problem of low crop yields due to exhaustion of nutrients in the soil has been related to rainforest destruction. In Asia, the specific amount of land needed for sustainable farming is about 12.5 acres which include land for animal fodder, cereal production as a cash crop, and other food crops. In some cases, a small unit of aquaculture is included (AARI-1996). Nutrients Nitrates Nitrates are used widely in farming as fertilizer. Unfortunately, a major environmental problem associated with agriculture is the leaching of nitrates into the environment. Possible sources of nitrates that would, in principle, be available indefinitely, include: recycling crop waste and livestock or treated human manure growing legume crops and forages such as peanuts or alfalfa that form symbioses with nitrogen-fixing bacteria called rhizobia industrial production of nitrogen by the Haber process uses hydrogen, which is currently derived from natural gas (but this hydrogen could instead be made by electrolysis of water using renewable electricity) genetically engineering (non-legume) crops to form nitrogen-fixing symbioses or fix nitrogen without microbial symbionts. The last option was proposed in the 1970s, but is only gradually becoming feasible. Sustainable options for replacing other nutrient inputs such as phosphorus and potassium are more limited. Other options include long-term crop rotations, returning to natural cycles that annually flood cultivated lands (returning lost nutrients) such as the flooding of the Nile, the long-term use of biochar, and use of crop and livestock landraces that are adapted to less than ideal conditions such as pests, drought, or lack of nutrients. Crops that require high levels of soil nutrients can be cultivated in a more sustainable manner with appropriate fertilizer management practices. Phosphate Phosphate is a primary component in fertilizer. It is the second most important nutrient for plants after nitrogen, and is often a limiting factor. It is important for sustainable agriculture as it can improve soil fertility and crop yields. Phosphorus is involved in all major metabolic processes including photosynthesis, energy transfer, signal transduction, macromolecular biosynthesis, and respiration. It is needed for root ramification and strength and seed formation, and can increase disease resistance. Phosphorus is found in the soil in both inorganic and organic forms and makes up approximately 0.05% of soil biomass. Phosphorus fertilizers are the main input of inorganic phosphorus in agricultural soils and approximately 70%–80% of phosphorus in cultivated soils is inorganic. Long-term use of phosphate-containing chemical fertilizers causes eutrophication and deplete soil microbial life, so people have looked to other sources. Phosphorus fertilizers are manufactured from rock phosphate. However, rock phosphate is a non-renewable resource and it is being depleted by mining for agricultural use: peak phosphorus will occur within the next few hundred years, or perhaps earlier. Potassium Potassium is a macronutrient very important for plant development and is commonly sought in fertilizers. This nutrient is essential for agriculture because it improves water retention, nutrient value, yield, taste, color, texture and disease resistance of crops. It is often used in the cultivation of grains, fruits, vegetables, rice, wheat, millets, sugar, corn, soybeans, palm oil and coffee. Potassium chloride (KCl) represents the most widely source of K used in agriculture, accounting for 90% of all potassium produced for agricultural use.   The use of KCl leads to high concentrations of chloride (Clˉ) in soil harming its health due to the increase in soil salinity, imbalance in nutrient availability and this ion's biocidal effect for soil organisms. In consequences the development of plants and soil organisms is affected, putting at risk soil biodiversity and agricultural productivity. A sustainable option for replacing KCl are chloride-free fertilizers, its use should take into account plants' nutrition needs, and the promotion of soil health. Soil Land degradation is becoming a severe global problem. According to the Intergovernmental Panel on Climate Change: "About a quarter of the Earth's ice-free land area is subject to human-induced degradation (medium confidence). Soil erosion from agricultural fields is estimated to be currently 10 to 20 times (no tillage) to more than 100 times (conventional tillage) higher than the soil formation rate (medium confidence)." Almost half of the land on earth is covered with dry land, which is susceptible to degradation. Over a billion tonnes of southern Africa's soil are being lost to erosion annually, which if continued will result in halving of crop yields within thirty to fifty years. Improper soil management is threatening the ability to grow sufficient food. Intensive agriculture reduces the carbon level in soil, impairing soil structure, crop growth and ecosystem functioning, and accelerating climate change. Modification of agricultural practices is a recognized method of carbon sequestration as soil can act as an effective carbon sink. Soil management techniques include no-till farming, keyline design and windbreaks to reduce wind erosion, reincorporation of organic matter into the soil, reducing soil salinization, and preventing water run-off. Land As the global population increases and demand for food increases, there is pressure on land as a resource. In land-use planning and management, considering the impacts of land-use changes on factors such as soil erosion can support long-term agricultural sustainability, as shown by a study of Wadi Ziqlab, a dry area in the Middle East where farmers graze livestock and grow olives, vegetables, and grains. Looking back over the 20th century shows that for people in poverty, following environmentally sound land practices has not always been a viable option due to many complex and challenging life circumstances. Currently, increased land degradation in developing countries may be connected with rural poverty among smallholder farmers when forced into unsustainable agricultural practices out of necessity. Converting big parts of the land surface to agriculture has severe environmental and health consequences. For example, it leads to rise in zoonotic disease (like the Coronavirus disease 2019) due to the degradation of natural buffers between humans and animals, reducing biodiversity and creating larger groups of genetically similar animals. Land is a finite resource on Earth. Although expansion of agricultural land can decrease biodiversity and contribute to deforestation, the picture is complex; for instance, a study examining the introduction of sheep by Norse settlers (Vikings) to the Faroe Islands of the North Atlantic concluded that, over time, the fine partitioning of land plots contributed more to soil erosion and degradation than grazing itself. The Food and Agriculture Organization of the United Nations estimates that in coming decades, cropland will continue to be lost to industrial and urban development, along with reclamation of wetlands, and conversion of forest to cultivation, resulting in the loss of biodiversity and increased soil erosion. Energy In modern agriculture, energy is used in on-farm mechanisation, food processing, storage, and transportation processes. It has therefore been found that energy prices are closely linked to food prices. Oil is also used as an input in agricultural chemicals. The International Energy Agency projects higher prices of non-renewable energy resources as a result of fossil fuel resources being depleted. It may therefore decrease global food security unless action is taken to 'decouple' fossil fuel energy from food production, with a move towards 'energy-smart' agricultural systems including renewable energy. The use of solar powered irrigation in Pakistan is said to be a closed system for agricultural water irrigation. The environmental cost of transportation could be avoided if people use local products. Water In some areas sufficient rainfall is available for crop growth, but many other areas require irrigation. For irrigation systems to be sustainable, they require proper management (to avoid salinization) and must not use more water from their source than is naturally replenishable. Otherwise, the water source effectively becomes a non-renewable resource. Improvements in water well drilling technology and submersible pumps, combined with the development of drip irrigation and low-pressure pivots, have made it possible to regularly achieve high crop yields in areas where reliance on rainfall alone had previously made successful agriculture unpredictable. However, this progress has come at a price. In many areas, such as the Ogallala Aquifer, the water is being used faster than it can be replenished. According to the UC Davis Agricultural Sustainability Institute, several steps must be taken to develop drought-resistant farming systems even in "normal" years with average rainfall. These measures include both policy and management actions: improving water conservation and storage measures providing incentives for selection of drought-tolerant crop species using reduced-volume irrigation systems managing crops to reduce water loss not planting crops at all. Indicators for sustainable water resource development include the average annual flow of rivers from rainfall, flows from outside a country, the percentage of water coming from outside a country, and gross water withdrawal. It is estimated that agricultural practices consume 69% of the world's fresh water. Social factors Rural economic development Sustainable agriculture attempts to solve multiple problems with one broad solution. The goal of sustainable agricultural practices is to decrease environmental degradation due to farming while increasing crop–and thus food–output. There are many varying strategies attempting to use sustainable farming practices in order to increase rural economic development within small-scale farming communities. Two of the most popular and opposing strategies within the modern discourse are allowing unrestricted markets to determine food production and deeming food a human right. Neither of these approaches have been proven to work without fail. A promising proposal to rural poverty reduction within agricultural communities is sustainable economic growth; the most important aspect of this policy is to regularly include the poorest farmers in the economy-wide development through the stabilization of small-scale agricultural economies. In 2007, the United Nations reported on "Organic Agriculture and Food Security in Africa", stating that using sustainable agriculture could be a tool in reaching global food security without expanding land usage and reducing environmental impacts. There has been evidence provided by developing nations from the early 2000s stating that when people in their communities are not factored into the agricultural process that serious harm is done. The social scientist Charles Kellogg has stated that, "In a final effort, exploited people pass their suffering to the land." Sustainable agriculture mean the ability to permanently and continuously "feed its constituent populations". There are a lot of opportunities that can increase farmers' profits, improve communities, and continue sustainable practices. For example, in Uganda, Genetically Modified Organisms were originally illegal. However, with the stress of banana crisis in Uganda, where Banana Bacterial Wilt had the potential to wipe out 90% of yield, they decided to explore GMOs as a possible solution. The government issued the National Biotechnology and Biosafety bill, which will allow scientists that are part of the National Banana Research Program to start experimenting with genetically modified organisms. This effort has the potential to help local communities because a significant portion live off the food they grow themselves, and it will be profitable because the yield of their main produce will remain stable. Not all regions are suitable for agriculture. The technological advancement of the past few decades has allowed agriculture to develop in some of these regions. For example, Nepal has built greenhouses to deal with its high altitude and mountainous regions. Greenhouses allow for greater crop production and also use less water since they are closed systems. Desalination techniques can turn salt water into fresh water which allows greater access to water for areas with a limited supply. This allows the irrigation of crops without decreasing natural fresh water sources. While desalination can be a tool to provide water to areas that need it to sustain agriculture, it requires money and resources. Regions of China have been considering large scale desalination in order to increase access to water, but the current cost of the desalination process makes it impractical. Women Women working in sustainable agriculture come from numerous backgrounds, ranging from academia to labour. From 1978-2007, in the United States, the number of women farm operators has tripled. In 2007, women operated 14 percent of farms, compared to five percent in 1978. Much of the growth is due to women farming outside of the "male dominated field of conventional agriculture". Growing your own food The practice of growing food in the backyard of houses, schools, etc., by families or by communities became widespread in the US at the time of World War I, the Great Depression and World War II, so that in one point of time 40% of the vegetables of the USA was produced in this way. The practice became more popular again in the time of the COVID-19 pandemic. This method permits to grow food in a relatively sustainable way and at the same time can make it easier for poor people to obtain food. Economic factors Costs, such as environmental problems, not covered in traditional accounting systems (which take into account only the direct costs of production incurred by the farmer) are known as externalities. Netting studied sustainability and intensive agriculture in smallholder systems through history. There are several studies incorporating externalities such as ecosystem services, biodiversity, land degradation, and sustainable land management in economic analysis. These include The Economics of Ecosystems and Biodiversity study and the Economics of Land Degradation Initiative which seek to establish an economic cost-benefit analysis on the practice of sustainable land management and sustainable agriculture. Triple bottom line frameworks include social and environmental alongside a financial bottom line. A sustainable future can be feasible if growth in material consumption and population is slowed down and if there is a drastic increase in the efficiency of material and energy use. To make that transition, long- and short-term goals will need to be balanced enhancing equity and quality of life. Challenges and debates Barriers The barriers to sustainable agriculture can be broken down and understood through three different dimensions. These three dimensions are seen as the core pillars to sustainability: social, environmental, and economic pillars. The social pillar addresses issues related to the conditions in which societies are born into, growing in, and learning from. It deals with shifting away from traditional practices of agricultural and moving into new sustainable practices that will create better societies and conditions. The environmental pillar addresses climate change and focuses on agricultural practices that protect the environment for future generations. The economic pillar discovers ways in which sustainable agriculture can be practiced while fostering economic growth and stability, with minimal disruptions to livelihoods. All three pillars must be addressed to determine and overcome the barriers preventing sustainable agricultural practices. Social barriers to sustainable agriculture include cultural shifts, the need for collaboration, incentives, and new legislation. The move from conventional to sustainable agriculture will require significant behavioural changes from both farmers and consumers. Cooperation and collaboration between farmers is necessary to successfully transition to sustainable practices with minimal complications. This can be seen as a challenge for farmers who care about competition and profitability. There must also be an incentive for farmers to change their methods of agriculture. The use of public policy, advertisements, and laws that make sustainable agriculture mandatory or desirable can be utilized to overcome these social barriers. Environmental barriers prevent the ability to protect and conserve the natural ecosystem. Examples of these barriers include the use of pesticides and the effects of climate change. Pesticides are widely used to combat pests that can devastate production and plays a significant role in keeping food prices and production costs low. To move toward sustainable agriculture, farmers are encouraged to utilize green pesticides, which cause less harm to both human health and habitats, but would entail a higher production cost. Climate change is also a rapidly growing barrier, one that farmers have little control over, which can be seen through place-based barriers. These place-based barriers include factors such as weather conditions, topography, and soil quality which can cause losses in production, resulting in the reluctance to switch from conventional practices. Many environmental benefits are also not visible or immediately evident. Significant changes such as lower rates of soil and nutrient loss, improved soil structure, and higher levels of beneficial microorganisms take time. In conventional agriculture, the benefits are easily visible with no weeds, pests, etc..., but the long term costs to the soil and surrounding ecosystems are hidden and "externalized". Conventional agricultural practices since the evolution of technology have caused significant damage to the environment through biodiversity loss, disrupted ecosystems, poor water quality, among other harms. The economic obstacles to implementing sustainable agricultural practices include low financial return/profitability, lack of financial incentives, and negligible capital investments. Financial incentives and circumstances play a large role in whether sustainable practices will be adopted. The human and material capital required to shift to sustainable methods of agriculture requires training of the workforce and making investments in new technology and products, which comes at a high cost. In addition to this, farmers practicing conventional agriculture can mass produce their crops, and therefore maximize their profitability. This would be difficult to do in sustainable agriculture which encourages low production capacity. The author James Howard Kunstler claims almost all modern technology is bad and that there cannot be sustainability unless agriculture is done in ancient traditional ways. Efforts toward more sustainable agriculture are supported in the sustainability community, however, these are often viewed only as incremental steps and not as an end. One promising method of encouraging sustainable agriculture is through local farming and community gardens. Incorporating local produce and agricultural education into schools, communities, and institutions can promote the consumption of freshly grown produce which will drive consumer demand. Some foresee a true sustainable steady state economy that may be very different from today's: greatly reduced energy usage, minimal ecological footprint, fewer consumer packaged goods, local purchasing with short food supply chains, little processed foods, more home and community gardens, etc. Different viewpoints about the definition There is a debate on the definition of sustainability regarding agriculture. The definition could be characterized by two different approaches: an ecocentric approach and a technocentric approach. The ecocentric approach emphasizes no- or low-growth levels of human development, and focuses on organic and biodynamic farming techniques with the goal of changing consumption patterns, and resource allocation and usage. The technocentric approach argues that sustainability can be attained through a variety of strategies, from the view that state-led modification of the industrial system like conservation-oriented farming systems should be implemented, to the argument that biotechnology is the best way to meet the increasing demand for food. One can look at the topic of sustainable agriculture through two different lenses: multifunctional agriculture and ecosystem services. Both of approaches are similar, but look at the function of agriculture differently. Those that employ the multifunctional agriculture philosophy focus on farm-centered approaches, and define function as being the outputs of agricultural activity. The central argument of multifunctionality is that agriculture is a multifunctional enterprise with other functions aside from the production of food and fiber. These functions include renewable resource management, landscape conservation and biodiversity. The ecosystem service-centered approach posits that individuals and society as a whole receive benefits from ecosystems, which are called "ecosystem services". In sustainable agriculture, the services that ecosystems provide include pollination, soil formation, and nutrient cycling, all of which are necessary functions for the production of food. It is also claimed sustainable agriculture is best considered as an ecosystem approach to agriculture, called agroecology. Ethics Most agricultural professionals agree that there is a "moral obligation to pursue [the] goal [of] sustainability." The major debate comes from what system will provide a path to that goal because if an unsustainable method is used on a large scale it will have a massive negative effect on the environment and human population. Methods Other practices include polyculture, growing a diverse number of perennial crops in a single field, each of which would grow in separate seasons so as not to compete with each other for natural resources. This system would result in increased resistance to diseases and decreased effects of erosion and loss of nutrients in the soil. Nitrogen fixation from legumes, for example, used in conjunction with plants that rely on nitrate from the soil for growth, helps to allow the land to be reused annually. Legumes will grow for a season and replenish the soil with ammonium and nitrate, and the next season other plants can be seeded and grown in the field in preparation for harvest. Sustainable methods of weed management may help reduce the development of herbicide-resistant weeds. Crop rotation may also replenish nitrogen if legumes are used in the rotations and may also use resources more efficiently. There are also many ways to practice sustainable animal husbandry. Some of the tools to grazing management include fencing off the grazing area into smaller areas called paddocks, lowering stock density, and moving the stock between paddocks frequently. Intensification An increased production is a goal of intensification. Sustainable intensification encompasses specific agriculture methods that increase production and at the same time help improve environmental outcomes. The desired outcomes of the farm are achieved without the need for more land cultivation or destruction of natural habitat; the system performance is upgraded with no net environmental cost. Sustainable Intensification has become a priority for the United Nations. Sustainable intensification differs from prior intensification methods by specifically placing importance on broader environmental outcomes. By 2018; it was predicted in 100 nations a combined total of 163 million farms used sustainable intensification. The amount of agricultural land covered by this is 453 million ha of land. That amount of land is equal to 29% of farms worldwide. In light of concerns about food security, human population growth and dwindling land suitable for agriculture, sustainable intensive farming practises are needed to maintain high crop yields, while maintaining soil health and ecosystem services. The capacity for ecosystem services to be strong enough to allow a reduction in use of non-renewable inputs whilst maintaining or boosting yields has been the subject of much debate. Recent work in irrigated rice production system of east Asia has suggested that – in relation to pest management at least – promoting the ecosystem service of biological control using nectar plants can reduce the need for insecticides by 70% whilst delivering a 5% yield advantage compared with standard practice. Vertical farming is a concept with the potential advantages of year-round production, isolation from pests and diseases, controllable resource recycling and reduced transportation costs. Water Water efficiency can be improved by reducing the need for irrigation and using alternative methods. Such methods include: researching on drought resistant crops, monitoring plant transpiration and reducing soil evaporation. Drought resistant crops have been researched extensively as a means to overcome the issue of water shortage. They are modified genetically so they can adapt in an environment with little water. This is beneficial as it reduces the need for irrigation and helps conserve water. Although they have been extensively researched, significant results have not been achieved as most of the successful species will have no overall impact on water conservation. However, some grains like rice, for example, have been successfully genetically modified to be drought resistant. Soil and nutrients Soil amendments include using compost from recycling centers. Using compost from yard and kitchen waste uses available resources in the area. Abstinence from soil tillage before planting and leaving the plant residue after harvesting reduces soil water evaporation; It also serves to prevent soil erosion. Crop residues left covering the surface of the soil may result in reduced evaporation of water, a lower surface soil temperature, and reduction of wind effects. A way to make rock phosphate more effective is to add microbial inoculates such as phosphate-solubilizing microorganisms, known as PSMs, to the soil. These solubilize phosphorus already in the soil and use processes like organic acid production and ion exchange reactions to make that phosphorus available for plants. Experimentally, these PSMs have been shown to increase crop growth in terms of shoot height, dry biomass and grain yield. Phosphorus uptake is even more efficient with the presence of mycorrhizae in the soil. Mycorrhiza is a type of mutualistic symbiotic association between plants and fungi, which are well-equipped to absorb nutrients, including phosphorus, in soil. These fungi can increase nutrient uptake in soil where phosphorus has been fixed by aluminum, calcium, and iron. Mycorrhizae can also release organic acids that solubilize otherwise unavailable phosphorus. Pests and weeds Soil steaming can be used as an alternative to chemicals for soil sterilization. Different methods are available to induce steam into the soil to kill pests and increase soil health. Solarizing is based on the same principle, used to increase the temperature of the soil to kill pathogens and pests. Certain plants can be cropped for use as biofumigants, "natural" fumigants, releasing pest suppressing compounds when crushed, ploughed into the soil, and covered in plastic for four weeks. Plants in the Brassicaceae family release large amounts of toxic compounds such as methyl isothiocyanates. Location Relocating current croplands to environmentally more optimal locations, whilst allowing ecosystems in then-abandoned areas to regenerate could substantially decrease the current carbon, biodiversity, and irrigation water footprint of global crop production, with relocation only within national borders also having substantial potential. Plants Sustainability may also involve crop rotation. Crop rotation and cover crops prevent soil erosion, by protecting topsoil from wind and water. Effective crop rotation can reduce pest pressure on crops, provides weed control, reduces disease build up, and improves the efficiency of soil nutrients and nutrient cycling. This reduces the need for fertilizers and pesticides. Increasing the diversity of crops by introducing new genetic resources can increase yields by 10 to 15 percent compared to when they are grown in monoculture. Perennial crops reduce the need for tillage and thus help mitigate soil erosion, and may sometimes tolerate drought better, increase water quality and help increase soil organic matter. There are research programs attempting to develop perennial substitutes for existing annual crops, such as replacing wheat with the wild grass Thinopyrum intermedium, or possible experimental hybrids of it and wheat. Being able to do all of this without the use of chemicals is one of the main goals of sustainability which is why crop rotation is a very central method of sustainable agriculture. Related concepts Organic agriculture Organic agriculture can be defined as: {{blockquote|an integrated farming system that strives for sustainability, the enhancement of soil fertility and biological diversity whilst, with rare exceptions, prohibiting synthetic pesticides, antibiotics, synthetic fertilizers, genetically modified organisms, and growth hormones.<ref>H. Martin, '’Ontario Ministry of Agriculture, Food and Rural Affairs Introduction to Organic Farming, </ref>}} Some claim organic agriculture may produce the most sustainable products available for consumers in the US, where no other alternatives exist, although the focus of the organics industry is not sustainability. In 2018 the sales of organic products in USA reach $52.5 billion According to a USDA survey two-thirds of Americans consume organic products at least occasionally. Ecological farming Ecological farming is a concept that focused on the environmental aspects of sustainable agriculture. Ecological farming includes all methods, including organic, which regenerate ecosystem services like: prevention of soil erosion, water infiltration and retention, carbon sequestration in the form of humus, and increased biodiversity. Many techniques are used including no-till farming, multispecies cover crops, strip cropping, terrace cultivation, shelter belts, pasture cropping etc. There are a plethora of methods and techniques that are employed when practicing ecological farming, all having their own unique benefits and implementations that lead to more sustainable agriculture. Crop genetic diversity is one method that is used to reduce the risks associated with monoculture crops, which can be susceptible to a changing climate. This form of biodiversity causes crops to be more resilient, increasing food security and enhancing the productivity of the field on a long-term scale. The use of biodigestors is another method which converts organic waste into a combustible gas, which can provide several benefits to an ecological farm: it can be used as a fuel source, fertilizer for crops and fish ponds, and serves as a method for removing wastes that are rich in organic matter. Because biodigestors can be used as fertilizer, it reduces the amount of industrial fertilizers that are needed to sustain the yields of the farm. Another technique used is aquaculture integration, which combines fish farming with agricultural farming, using the wastes from animals and crops and diverting them towards the fish farms to be used up instead of being leeched into the environment. Mud from the fish ponds can also be used to fertilize crops. Organic Fertilizers can also be employed in an ecological farm, such as animal and green manure. This allows soil fertility to be improved and well-maintained, leads to reduced costs and increased yields, reduces the usage of non-renewable resources in industrial fertilizers (Nitrogen and Phosphorus), and reduces the environmental pressures that are posed by intensive agricultural systems. Precision Agriculture can also be used, which focuses on efficient removal of pests using non-chemical techniques and minimizes the amount of tilling needed to sustain the farm. An example of a precision machine is the false seedbed tiller, which can remove a great majority of small weeds while only tilling one centimeter deep. This minimized tilling reduces the amount of new weeds that germinate from soil disturbance. Other methods that reduce soil erosion include contour farming, strip cropping, and terrace cultivation. Benefits Ecological farming involves the introduction of symbiotic species, where possible, to support the ecological sustainability of the farm. Associated benefits include a reduction in ecological debt and elimination of dead zones. Ecological farming is a pioneering, practical development which aims to create globally sustainable land management systems, and encourages review of the importance of maintaining biodiversity in food production and farming end products. One foreseeable option is to develop specialized automata to scan and respond to soil and plant situations relative to intensive care for the soil and the plants. Accordingly, conversion to ecological farming may best utilize the information age, and become recognised as a primary user of robotics and expert systems. Challenges The challenge for ecological farming science is to be able to achieve a mainstream productive food system that is sustainable or even regenerative. To enter the field of ecological farming, location relative to the consumer, can reduce the food miles factor to help minimise damage to the biosphere by combustion engine emissions involved in current food transportation. Design of the ecological farm is initially constrained by the same limitations as conventional farming: local climate, the soil's physical properties, budget for beneficial soil supplements, manpower and available automatons; however long-term water management by ecological farming methods is likely to conserve and increase water availability for the location, and require far fewer inputs to maintain fertility. Principles Certain principles unique to ecological farming need to be considered. Food production should be ecological in both origin and destiny (the term destiny refers to the post-harvest ecological footprint which results in getting produce to the consumer). Integration of species that maintain ecosystem services whilst providing a selection of alternative products. Minimise food miles, packaging, energy consumption and waste. Define a new ecosystem to suit human needs using lessons from existing ecosystems from around the world.Nutrient dense food species Apply the value of a knowledge-base (advanced data base) about soil microorganisms so that discoveries of the ecological benefits of having various kinds of microorganisms encouraged in productive systems such as Forest Gardens can be assessed and optimised; for example in the case of naturally occurring microorganisms called denitrifiers. Traditional agriculture Often thought of as inherently destructive, slash-and-burn or slash-and-char shifting cultivation have been practiced in the Amazon for thousands of years. Some traditional systems combine polyculture with sustainability. In South-East Asia, rice-fish systems on rice paddies have raised freshwater fish as well as rice, producing an additional product and reducing eutrophication of neighboring rivers. A variant in Indonesia combines rice, fish, ducks and water fern; the ducks eat the weeds that would otherwise limit rice growth, saving labour and herbicides, while the duck and fish manure substitute for fertilizer. Raised field agriculture has been recently revived in certain areas of the world, such as the Altiplano region in Bolivia and Peru. This has resurged in the form of traditional Waru Waru raised fields, which create nutrient-rich soil in regions where such soil is scarce. This method is extremely productive and has recently been utilized by indigenous groups in the area and the nearby Amazon Basin to make use of lands that have been historically hard to cultivate. Other forms of traditional agriculture include agro forestry, crop rotations, and water harvesting. Water harvesting is one of the largest and most common practices, particularly used in dry areas and seasons. In Ethiopia, over half of their GDP and over 80 percent of their exports are attributed to agriculture; yet, it is known for its intense droughts and dry periods. Rain water harvesting is considered to be a low-cost alternative. This type of harvesting collects and stores water from roof tops during high-rain periods for use during droughts. Rainwater harvesting has been a large practice to help the country survive by focusing on runoff irrigation, roof water harvesting, and flood spreading. Indigenous Agriculture in North America Native Americans in the United States practiced sustainable agriculture through their subsistence farming techniques. Many tribes grew or harvested their own food from plants that thrived in their local ecosystems. Native American farming practices are specific to local environments and work with natural processes. This is a practice called Permaculture, and it involves a deep understanding of the local environment. Native American farming techniques also incorporate local biodiversity into many of their practices, which helps the land remain healthy. Many indigenous tribes incorporated Intercropping into their agriculture, which is a practice where multiple crops are planted together in the same area. This strategy allows crops to help one another grow through exchanged nutrients, maintained soil moisture, and physical supports for one another. The crops that are paired in intercropping often do not heavily compete for resources, which helps them to each be successful. For example, many tribes utilized intercropping in ways such as the Three Sisters Garden. This gardening technique consists of corn, beans, and squash. These crops grow in unity as the corn stalk supports the beans, the beans produce nitrogen, and the squash retain moisture. Intercropping also provides a natural strategy for pest management and the prevention of weed growth. Intercropping is a natural agricultural practice that often improves the overall health of the soil and plants, increases crop yield, and is sustainable. One of the most significant aspects of indigenous sustainable agriculture is their traditional ecological knowledge of harvesting. The Anishinaabe tribes follow an ideology known as "the Honorable Harvest". The Honorable Harvest is a set of practices that emphasize the idea that people should "take only what you need and use everything you take." Resources are conserved through this practice because several rules are followed when harvesting a plant. These rules are to never take the first plant, never take more than half of the plants, and never take the last plant. This encourages future growth of the plant and therefore leads to a sustainable use of the plants in the area. Native Americans practiced agroforestry by managing the forest, animals, and crops together. They also helped promote tree growth through controlled burns and silviculture. Often, the remaining ash from these burns would be used to fertilize their crops. By improving the conditions of the forest, the local wildlife populations also increased. Native Americans allowed their livestock to graze in the forest, which provided natural fertilizer for the trees as well. Regenerative agriculture Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, improving the water cycle, enhancing ecosystem services, supporting biosequestration, increasing resilience to climate change, and strengthening the health and vitality of farm soil. Practices include, recycling as much farm waste as possible, and adding composted material from sources outside the farm. Alternative methods Permaculture Polyculture There is limited evidence polyculture may contribute to sustainable agriculture. A meta-analysis of a number of polycrop studies found that predator insect biodiversity was higher at comparable yields than conventional in certain two-crop systems with a single cash crop combined with a cover crop. One approach to sustainability is to develop polyculture systems using perennial crop varieties. Such varieties are being developed for rice, wheat, sorghum, barley, and sunflowers. If these can be combined in polyculture with a leguminous cover crop such as alfalfa, fixation of nitrogen will be added to the system, reducing the need for fertilizer and pesticides. Local small-scale agriculture The use of available city space (e.g., rooftop gardens, community gardens, garden sharing, organopónicos, and other forms of urban agriculture) may be able to contribute to sustainability. Some consider "guerrilla gardening" an example of sustainability in action – in some cases seeds of edible plants have been sown in local rural areas. Hydroponics or soil-less culture Hydroponics is an alternative to agriculture that creates the ideal environment for optimal growth without using a dormant medium. This innovative farming technique produces higher crop yields without compromising soil health. The most significant drawback of this sustainable farming technique is the cost associated with development. Standards Certification systems are important to the agriculture community and to consumers as these standards determine the sustainability of produce. Numerous sustainability standards and certification systems exist, including organic certification, Rainforest Alliance, Fair Trade, UTZ Certified, GlobalGAP, Bird Friendly, and the Common Code for the Coffee Community (4C). These standards specify rules that producers, manufacturers and traders need to follow so that the things they do, make, or grow do not hurt people and the environment. These standards are also known as Voluntary Sustainability Standards (VSS) that are private standards that require products to meet specific economic, social or environmental sustainability metrics. The requirements can refer to product quality or attributes, but also to production and processing methods, as well as transportation. VSS are mostly designed and marketed by non-governmental organizations (NGOs) or private firms and they are adopted by actors up and down the value chain, from farmers to retailers. Certifications and labels are used to signal the successful implementation of a VSS. According to the ITC standards map the mostly covered products by standards are agricultural products. Around 500 VSS today apply to key exports of many developing countries, such as coffee, tea, bananas, cocoa, palm oil, timber, cotton, and organic agri-foods. VSS are found to reduce eutrophication, water use, greenhouse gas emissions, and natural ecosystem conversion. And thus are considered as a potential tool for sustainable agriculture. The USDA produces an organic label that is supported by nationalized standards of farmers and facilities. The steps for certification consist of creating an organic system plan, which determines how produce will be tilled, grazed, harvested, stored, and transported. This plan also manages and monitors the substances used around the produce, the maintenance needed to protect the produce, and any nonorganic products that may come in contact with the produce. The organic system plan is then reviewed and inspected by the USDA certifying agent. Once the certification is granted, the produce receives an approval sticker from the USDA and the produce is distributed across the U.S. In order to hold farmers accountable and ensure that Americans are receiving organic produce, these inspections are done at least once a year. This is just one example of sustainable certification systems through produce maintenance. Policy Sustainable agriculture is a topic in international policy concerning its potential to reduce environmental risks. In 2011, the Commission on Sustainable Agriculture and Climate Change, as part of its recommendations for policymakers on achieving food security in the face of climate change, urged that sustainable agriculture must be integrated into national and international policy. The Commission stressed that increasing weather variability and climate shocks will negatively affect agricultural yields, necessitating early action to drive change in agricultural production systems towards increasing resilience. It also called for dramatically increased investments in sustainable agriculture in the next decade, including in national research and development budgets, land rehabilitation, economic incentives, and infrastructure improvement. At the global level During 2021 United Nations Climate Change Conference, 45 countries pledged to give more than 4 billion dollars for transition to sustainable agriculture. The organization "Slow Food" expressed concern about the effectivity of the spendings, as they concentrate on technological solutions and reforestation en place of "a holistic agroecology that transforms food from a mass-produced commodity into part of a sustainable system that works within natural boundaries." Additionally, the Summit consisted of negotiations that led to heavily reducing CO2 emissions, becoming carbon neutral, ending deforestation and reliance on coal, and limiting methane emissions. In November, the Climate Action Tracker reported that global efforts are on track to for a 2.7 °C temperature increase with current policies, finding that the current targets will not meet global needs as coal and natural gas consumption are primarily responsible for the gap in progress. Since, like-minded developing countries asked for an addendum to the agreement that removed the obligation for developing countries to meet the same requirements of wealthy nations. European Union In May 2020 the European Union published a program, named "From Farm to Fork" for making its agriculture more sustainable. In the official page of the program From Farm to Fork is cited Frans Timmermans the Executive Vice-President of the European Commission, saying that: The program includes the next targets: Making 25% of EU agriculture organic, by 2030. Reduce by 50% the use of pesticides by 2030. Reduce the use of fertilizers by 20% by 2030. Reduce nutrient loss by at least 50%. Reduce the use of antimicrobials in agriculture and antimicrobials in aquaculture by 50% by 2030. Create sustainable food labeling. Reduce food waste by 50% by 2030. Dedicate to R&I related to the issue €10 billion. United States Policies from 1930 - 2000 The New Deal implemented policies and programs that promoted sustainable agriculture. Under the Agriculture Adjustment Act of 1933, it provided farmers payments to create a supply management regime that capped production of important crops. This allowed farmers to focus on growing food and not competing in the market based system. The New Deal also provided a monetary incentive for farmers that left some of their fields unsown or ungrazed to order to improve the soil conditions. The Cooperative Extension Service was also established that set up sharing funding responsibilities amongst the USDA, land-grant universities, and local communities. The 1950s to 1990s was when the government switched its stance on agriculture policy which halted sustainable agriculture. The Agricultural Act of 1954 passed which supported farmers with flexible price supports, but only to commodity programs. The Food and Agricultural Act of 1965 had new income support payments and continued supply controls but reduced priced supports. Agriculture and Consumer Protection Act of 1973 removed price supports and instead introduced target prices and deficiency payments. It continued to promote commodity crops by lowering interest rates. Food Security Act of 1985 continued commodity loan programs. These policies incentivized profit over sustainability because the US government was promoting farms to maximize their production output instead of placing checks. This meant that farms were being turned into food factories as they became bigger in size and grew more commodity crops like corn, wheat, and cotton. From 1900 to 2002, the number of farms in the US decreased significantly while the average size of a farm went up after 1950. Current Policies In the United States, the federal Natural Resources Conservation Service (USDA) provides technical and financial assistance for those interested in pursuing natural resource conservation along with production agriculture. With programs like SARE and China-UK SAIN to help promote research on sustainable agriculture practices and a framework for agriculture and climate change respectively. Future Policies Currently, there are policies on the table that could move the US agriculture system into a more sustainable direction with the Green New Deal. This policy promotes decentralizing agrarian governance by breaking up large commodity farms that were created in the 1950s to 1980s. Decentralized governance within the farming community would allow for more adaptive management at local levels to help focus on climate change mitigation, food security, and landscape-scale ecological stewardship. The Green New Deal would invest in public infrastructure to support farmers transition from industrial food regime and acquire agroecological skills. Just like in the New Deal, it would invest in cooperatives and commons to share and redistribute resources like land, food, equipment, research facilities, personnel, and training programs. All of these policies and programs would break down barriers that have prevented sustainable farmers and agriculture from taking place in the United States. Asia China In 2016, the Chinese government adopted a plan to reduce China's meat consumption by 50%, for achieving more sustainable and healthy food system. In 2019, the National Basic Research Program or Program 973 funded research into Science and Technology Backyard (STB). STBs are hubs often created in rural areas with significant rates of small-scale farming that combine knowledge of traditional practices with new innovations and technology implementation. The purpose of this program was to invest in sustainable farming throughout the country and increase food production while achieving few negative environmental effects. The program was ultimately proven to be successful, and the study found that the merging of traditional practices and appropriate technology was instrumental in higher crop yields. India In collaboration with the Food and Land Use Coalition (FOLU), CEEW (council for energy, environment and water), has given an overview of the current state of sustainable agriculture practices and systems (SAPSs) in India. India is aiming to scale-up SAPs, through policymakers, administrators, philanthropists, and other which represent a vital alternative to conventional, input-intensive agriculture. In idea these efforts identify 16 SAPSs – including agroforestry, crop rotation, rainwater harvesting, organic farming and natural farming – using agroecology as an investigative lens. In a conclusive understanding it is realised that sustainable agriculture is far from mainstream in India. Further proposals for several measures for promoting SAPSs, including restructured government support and rigorous evidence generation for benefits and implementation of sustainable farming are ongoing progress in Indian Agriculture. An example of initiatives in India towards exploring the world of sustainable farming has been set by the Sowgood foundation which is a nonprofit founded by educator Pragati Chaswal. It started by teaching primary school children about sustainable farming by helping them farm on small farm strips in suburban farmhouses and gardens. Today many government and private schools in Delhi, India have adopted the sowgood foundation curriculum for sustainable farming for their students. Other countries Israel In 2012, the Israeli Ministry of Agriculture found itself at the height of the Israeli commitment to sustainable agriculture policy. A large factor of this policy was funding programs that made sustainable agriculture accessible to smaller Palestinian-Arab communities. The program was meant to create biodiversity, train farmers in sustainable agriculture methods, and hold regular meetings for agriculture stakeholders. This plan was not well-accepted by all as opposers argue that the plan creates a new social construct and a tool for the government to hold more power. History In 1907, the American author Franklin H. King discussed in his book Farmers of Forty Centuries'' the advantages of sustainable agriculture and warned that such practices would be vital to farming in the future. The phrase 'sustainable agriculture' was reportedly coined by the Australian agronomist Gordon McClymont. The term became popular in the late 1980s. There was an international symposium on sustainability in horticulture by the International Society of Horticultural Science at the International Horticultural Congress in Toronto in 2002. At the following conference at Seoul in 2006, the principles were discussed further. This potential future inability to feed the world's population has been a concern since the English political economist Thomas Malthus in the early 1800s, but has become increasingly important recently. Starting at the very end of the twentieth and early twenty-first centuries, this issue became widely discussed in the U.S. because of growing anxieties of a rapidly increasing global population. Agriculture has long been the biggest industry worldwide and requires significant land, water, and labor inputs. At the turn of the twenty-first century, experts questioned the industry's ability to keep up with population growth. This debate led to concerns over global food insecurity and "solving hunger".

Earth science

Earth science or geoscience includes all fields of natural science related to the planet Earth. This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres: the biosphere, hydrosphere/cryosphere, atmosphere, and geosphere (or lithosphere). Earth science can be considered to be a branch of planetary science but with a much older history. Geology Geology is broadly the study of Earth's structure, substance, and processes. Geology is largely the study of the lithosphere, or Earth's surface, including the crust and rocks. It includes the physical characteristics and processes that occur in the lithosphere as well as how they are affected by geothermal energy. It incorporates aspects of chemistry, physics, and biology as elements of geology interact. Historical geology is the application of geology to interpret Earth history and how it has changed over time. Geochemistry studies the chemical components and processes of the Earth. Geophysics studies the physical properties of the Earth. Paleontology studies fossilized biological material in the lithosphere. Planetary geology studies geoscience as it pertains to extraterrestrial bodies. Geomorphology studies the origin of landscapes. Structural geology studies the deformation of rocks to produce mountains and lowlands. Resource geology studies how energy resources can be obtained from minerals. Environmental geology studies how pollution and contaminants affect soil and rock. Mineralogy is the study of minerals and includes the study of mineral formation, crystal structure, hazards associated with minerals, and the physical and chemical properties of minerals. Petrology is the study of rocks, including the formation and composition of rocks. Petrography is a branch of petrology that studies the typology and classification of rocks. Earth's interior Plate tectonics, mountain ranges, volcanoes, and earthquakes are geological phenomena that can be explained in terms of physical and chemical processes in the Earth's crust. Beneath the Earth's crust lies the mantle which is heated by the radioactive decay of heavy elements. The mantle is not quite solid and consists of magma which is in a state of semi-perpetual convection. This convection process causes the lithospheric plates to move, albeit slowly. The resulting process is known as plate tectonics. Areas of the crust where new crust is created are called divergent boundaries, those where it is brought back into the Earth are convergent boundaries and those where plates slide past each other, but no new lithospheric material is created or destroyed, are referred to as transform (or conservative) boundaries. Earthquakes result from the movement of the lithospheric plates, and they often occur near convergent boundaries where parts of the crust are forced into the earth as part of subduction. Plate tectonics might be thought of as the process by which the Earth is resurfaced. As the result of seafloor spreading, new crust and lithosphere is created by the flow of magma from the mantle to the near surface, through fissures, where it cools and solidifies. Through subduction, oceanic crust and lithosphere vehemently returns to the convecting mantle. Volcanoes result primarily from the melting of subducted crust material. Crust material that is forced into the asthenosphere melts, and some portion of the melted material becomes light enough to rise to the surface—giving birth to volcanoes. Atmospheric science Atmospheric science initially developed in the late-19th century as a means to forecast the weather through meteorology, the study of weather. Atmospheric chemistry was developed in the 20th century to measure air pollution and expanded in the 1970s in response to acid rain. Climatology studies the climate and climate change. The troposphere, stratosphere, mesosphere, thermosphere, and exosphere are the five layers which make up Earth's atmosphere. 75% of the mass in the atmosphere is located within the troposphere, the lowest layer. In all, the atmosphere is made up of about 78.0% nitrogen, 20.9% oxygen, and 0.92% argon, and small amounts of other gases including CO2 and water vapor. Water vapor and CO2 cause the Earth's atmosphere to catch and hold the Sun's energy through the greenhouse effect. This makes Earth's surface warm enough for liquid water and life. In addition to trapping heat, the atmosphere also protects living organisms by shielding the Earth's surface from cosmic rays. The magnetic field—created by the internal motions of the core—produces the magnetosphere which protects Earth's atmosphere from the solar wind. As the Earth is 4.5 billion years old, it would have lost its atmosphere by now if there were no protective magnetosphere. Earth's magnetic field Hydrology Hydrology is the study of the hydrosphere and the movement of water on Earth. It emphasizes the study of how humans use and interact with freshwater supplies. Study of water's movement is closely related to geomorphology and other branches of Earth science. Applied hydrology involves engineering to maintain aquatic environments and distribute water supplies. Subdisciplines of hydrology include oceanography, hydrogeology, ecohydrology, and glaciology. Oceanography is the study of oceans. Hydrogeology is the study of groundwater. It includes the mapping of groundwater supplies and the analysis of groundwater contaminants. Applied hydrogeology seeks to prevent contamination of groundwater and mineral springs and make it available as drinking water. The earliest exploitation of groundwater resources dates back to 3000 BC, and hydrogeology as a science was developed by hydrologists beginning in the 17th century. Ecohydrology is the study of ecological systems in the hydrosphere. It can be divided into the physical study of aquatic ecosystems and the biological study of aquatic organisms. Ecohydrology includes the effects that organisms and aquatic ecosystems have on one another as well as how these ecoystems are affected by humans. Glaciology is the study of the cryosphere, including glaciers and coverage of the Earth by ice and snow. Concerns of glaciology include access to glacial freshwater, mitigation of glacial hazards, obtaining resources that exist beneath frozen land, and addressing the effects of climate change on the cryosphere. Ecology Ecology is the study of the biosphere. This includes the study of nature and of how living things interact with the Earth and one another and the consequences of that. It considers how living things use resources such as oxygen, water, and nutrients from the Earth to sustain themselves. It also considers how humans and other living creatures cause changes to nature. Physical geography Physical geography is the study of Earth's systems and how they interact with one another as part of a single self-contained system. It incorporates astronomy, mathematical geography, meteorology, climatology, geology, geomorphology, biology, biogeography, pedology, and soils geography. Physical geography is distinct from human geography, which studies the human populations on Earth, though it does include human effects on the environment. Methodology Methodologies vary depending on the nature of the subjects being studied. Studies typically fall into one of three categories: observational, experimental, or theoretical. Earth scientists often conduct sophisticated computer analysis or visit an interesting location to study earth phenomena (e.g. Antarctica or hot spot island chains). A foundational idea in Earth science is the notion of uniformitarianism, which states that "ancient geologic features are interpreted by understanding active processes that are readily observed." In other words, any geologic processes at work in the present have operated in the same ways throughout geologic time. This enables those who study Earth history to apply knowledge of how the Earth's processes operate in the present to gain insight into how the planet has evolved and changed throughout long history. Earth's spheres In Earth science, it is common to conceptualize the Earth's surface as consisting of several distinct layers, often referred to as spheres: the lithosphere, the hydrosphere, the atmosphere, and the biosphere, this concept of spheres is a useful tool for understanding the Earth's surface and its various processes these correspond to rocks, water, air and life. Also included by some are the cryosphere (corresponding to ice) as a distinct portion of the hydrosphere and the pedosphere (corresponding to soil) as an active and intermixed sphere. The following fields of science are generally categorized within the Earth sciences: Geology describes the rocky parts of the Earth's crust (or lithosphere) and its historic development. Major subdisciplines are mineralogy and petrology, geomorphology, paleontology, stratigraphy, structural geology, engineering geology, and sedimentology. Physical geography focuses on geography as an Earth science. Physical geography is the study of Earth's seasons, climate, atmosphere, soil, streams, landforms, and oceans. Physical geography can be divided into several branches or related fields, as follows: geomorphology, biogeography, environmental geography, palaeogeography, climatology, meteorology, coastal geography, hydrology, ecology, glaciology. Geophysics and geodesy investigate the shape of the Earth, its reaction to forces and its magnetic and gravity fields. Geophysicists explore the Earth's core and mantle as well as the tectonic and seismic activity of the lithosphere. Geophysics is commonly used to supplement the work of geologists in developing a comprehensive understanding of crustal geology, particularly in mineral and petroleum exploration. Seismologists use geophysics to understand plate tectonic movement, as well as predict seismic activity. Geochemistry is defined as the study of the processes that control the abundance, composition, and distribution of chemical compounds and isotopes in geologic environments. Geochemists use the tools and principles of chemistry to study the composition, structure, processes, and other physical aspects of the Earth. Major subdisciplines are aqueous geochemistry, cosmochemistry, isotope geochemistry and biogeochemistry. Soil science covers the outermost layer of the Earth's crust that is subject to soil formation processes (or pedosphere). Major subdivisions in this field of study include edaphology and pedology. Ecology covers the interactions between organisms and their environment. This field of study differentiates the study of Earth from the study of other planets in the Solar System, Earth being its only planet teeming with life. Hydrology, oceanography and limnology are studies which focus on the movement, distribution, and quality of the water and involves all the components of the hydrologic cycle on the Earth and its atmosphere (or hydrosphere). "Sub-disciplines of hydrology include hydrometeorology, surface water hydrology, hydrogeology, watershed science, forest hydrology, and water chemistry." Glaciology covers the icy parts of the Earth (or cryosphere). Atmospheric sciences cover the gaseous parts of the Earth (or atmosphere) between the surface and the exosphere (about 1000 km). Major subdisciplines include meteorology, climatology, atmospheric chemistry, and atmospheric physics. Earth science breakup Atmosphere Atmospheric chemistry Geography Climatology Meteorology Hydrometeorology Paleoclimatology Biosphere Biogeochemistry Biogeography Ecology Landscape ecology Geoarchaeology Geomicrobiology Paleontology Palynology Micropaleontology Hydrosphere Hydrology Hydrogeology Limnology (freshwater science) Oceanography (marine science) Chemical oceanography Physical oceanography Biological oceanography (marine biology) Geological oceanography (marine geology) Paleoceanography Lithosphere (geosphere) Geology Economic geology Engineering geology Environmental geology Forensic geology Historical geology Quaternary geology Planetary geology and planetary geography Sedimentology Stratigraphy Structural geology Geography Human geography Physical geography Geochemistry Geomorphology Geophysics Geochronology Geodynamics (see also Tectonics) Geomagnetism Gravimetry (also part of Geodesy) Seismology Glaciology Hydrogeology Mineralogy Crystallography Gemology Petrology Petrophysics Speleology Volcanology Pedosphere Geography Soil science Edaphology Pedology Systems Earth system science Environmental science Geography Human geography Physical geography Gaia hypothesis Systems ecology Systems geology Others Geography Cartography Geoinformatics (GIScience) Geostatistics Geodesy and Surveying Remote Sensing Hydrography Nanogeoscience See also American Geosciences Institute Earth sciences graphics software Four traditions of geography Glossary of geology terms List of Earth scientists List of geoscience organizations List of unsolved problems in geoscience Making North America National Association of Geoscience Teachers Solid-earth science Science tourism Structure of the Earth References Sources Further reading Allaby M., 2008.

Agronomy

Agronomy is the science and technology of producing and using plants by agriculture for food, fuel, fiber, chemicals, recreation, or land conservation. Agronomy has come to include research of plant genetics, plant physiology, meteorology, and soil science. It is the application of a combination of sciences such as biology, chemistry, economics, ecology, earth science, and genetics. Professionals of agronomy are termed agronomists. History Agronomy has a long and rich history dating to the Neolithic Revolution. Some of the earliest practices of agronomy are found in ancient civilizations, including Ancient Egypt, Mesopotamia, China and India. They developed various techniques for the management of soil fertility, irrigation and crop rotation. During the 18th and 19th centuries, advances in science led to the development of modern agronomy. German chemist Justus von Liebig and John Bennett Lawes, an English entrepreneur, contributed to the understanding of plant nutrition and soil chemistry. Their work laid for the establishment of modern fertilizers and agricultural practices. Agronomy continued to evolve with the development of new technology and practices in the 20th century. From the 1960s, the Green Revolution saw the introduction of high-yield variety of crops, modern fertilizers and improvement of agricultural practices. It led to an increase of global food production to help reduce hunger and poverty in many parts of the world. Plant breeding This topic of agronomy involves selective breeding of plants to produce the best crops for various conditions. Plant breeding has increased crop yields and has improved the nutritional value of numerous crops, including corn, soybeans, and wheat. It has also resulted in the development of new types of plants. For example, a hybrid grain named triticale was produced by crossbreeding rye and wheat. Triticale contains more usable protein than does either rye or wheat. Agronomy has also been instrumental for fruit and vegetable production research. Furthermore, the application of plant breeding for turfgrass development has resulted in a reduction in the demand for fertilizer and water inputs (requirements), as well as turf-types with higher disease resistance. Biotechnology Agronomists use biotechnology to extend and expedite the development of desired characteristics. Biotechnology is often a laboratory activity requiring field testing of new crop varieties that are developed. In addition to increasing crop yields agronomic biotechnology is being applied increasingly for novel uses other than food. For example, oilseed is at present used mainly for margarine and other food oils, but it can be modified to produce fatty acids for detergents, substitute fuels and petrochemicals. Soil science Agronomists study sustainable ways to make soils more productive and profitable. They classify soils and analyze them to determine whether they contain nutrients vital for plant growth. Common macronutrients analyzed include compounds of nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Soil is also assessed for several micronutrients, like zinc and boron. The percentage of organic matter, soil pH, and nutrient holding capacity (cation exchange capacity) are tested in a regional laboratory. Agronomists will interpret these laboratory reports and make recommendations to modify soil nutrients for optimal plant growth. Soil conservation Additionally, agronomists develop methods to preserve soil and decrease the effects of [erosion] by wind and water. For example, a technique known as contour plowing may be used to prevent soil erosion and conserve rainfall. Researchers of agronomy also seek ways to use the soil more effectively for solving other problems. Such problems include the disposal of human and animal manure, water pollution, and pesticide accumulation in the soil, as well as preserving the soil for future generations such as the burning of paddocks after crop production. Pasture management techniques include no-till farming, planting of soil-binding grasses along contours on steep slopes, and using contour drains of depths as much as 1 metre. Agroecology Agroecology is the management of agricultural systems with an emphasis on ecological and environmental applications. This topic is associated closely with work for sustainable agriculture, organic farming, and alternative food systems and the development of alternative cropping systems. Theoretical modeling Theoretical production ecology is the quantitative study of the growth of crops. The plant is treated as a kind of biological factory, which processes light, carbon dioxide, water, and nutrients into harvestable products. The main parameters considered are temperature, sunlight, standing crop biomass, plant production distribution, and nutrient and water supply.

Bioenergetics

Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to production and utilization of energy in forms such as adenosine triphosphate (ATP) molecules. That is, the goal of bioenergetics is to describe how living organisms acquire and transform energy in order to perform biological work. The study of metabolic pathways is thus essential to bioenergetics. Overview Bioenergetics is the part of biochemistry concerned with the energy involved in making and breaking of chemical bonds in the molecules found in biological organisms. It can also be defined as the study of energy relationships and energy transformations and transductions in living organisms. The ability to harness energy from a variety of metabolic pathways is a property of all living organisms. Growth, development, anabolism and catabolism are some of the central processes in the study of biological organisms, because the role of energy is fundamental to such biological processes. Life is dependent on energy transformations; living organisms survive because of exchange of energy between living tissues/ cells and the outside environment. Some organisms, such as autotrophs, can acquire energy from sunlight (through photosynthesis) without needing to consume nutrients and break them down. Other organisms, like heterotrophs, must intake nutrients from food to be able to sustain energy by breaking down chemical bonds in nutrients during metabolic processes such as glycolysis and the citric acid cycle. Importantly, as a direct consequence of the First Law of Thermodynamics, autotrophs and heterotrophs participate in a universal metabolic network—by eating autotrophs (plants), heterotrophs harness energy that was initially transformed by the plants during photosynthesis. In a living organism, chemical bonds are broken and made as part of the exchange and transformation of energy. Energy is available for work (such as mechanical work) or for other processes (such as chemical synthesis and anabolic processes in growth), when weak bonds are broken and stronger bonds are made. The production of stronger bonds allows release of usable energy. Adenosine triphosphate (ATP) is the main "energy currency" for organisms; the goal of metabolic and catabolic processes are to synthesize ATP from available starting materials (from the environment), and to break- down ATP (into adenosine diphosphate (ADP) and inorganic phosphate) by utilizing it in biological processes. In a cell, the ratio of ATP to ADP concentrations is known as the "energy charge" of the cell. A cell can use this energy charge to relay information about cellular needs; if there is more ATP than ADP available, the cell can use ATP to do work, but if there is more ADP than ATP available, the cell must synthesize ATP via oxidative phosphorylation. Living organisms produce ATP from energy sources via oxidative phosphorylation. The terminal phosphate bonds of ATP are relatively weak compared with the stronger bonds formed when ATP is hydrolyzed (broken down by water) to adenosine diphosphate and inorganic phosphate. Here it is the thermodynamically favorable free energy of hydrolysis that results in energy release; the phosphoanhydride bond between the terminal phosphate group and the rest of the ATP molecule does not itself contain this energy. An organism's stockpile of ATP is used as a battery to store energy in cells. Utilization of chemical energy from such molecular bond rearrangement powers biological processes in every biological organism. Living organisms obtain energy from organic and inorganic materials; i.e. ATP can be synthesized from a variety of biochemical precursors. For example, lithotrophs can oxidize minerals such as nitrates or forms of sulfur, such as elemental sulfur, sulfites, and hydrogen sulfide to produce ATP. In photosynthesis, autotrophs produce ATP using light energy, whereas heterotrophs must consume organic compounds, mostly including carbohydrates, fats, and proteins. The amount of energy actually obtained by the organism is lower than the amount present in the food; there are losses in digestion, metabolism, and thermogenesis. Environmental materials that an organism intakes are generally combined with oxygen to release energy, although some nutrients can also be oxidized anaerobically by various organisms. The utilization of these materials is a form of slow combustion because the nutrients are reacted with oxygen (the materials are oxidized slowly enough that the organisms do not produce fire). The oxidation releases energy, which may evolve as heat or be used by the organism for other purposes, such as breaking chemical bonds. Types of reactions An exergonic reaction is a spontaneous chemical reaction that releases energy. It is thermodynamically favored, indexed by a negative value of ΔG (Gibbs free energy). Over the course of a reaction, energy needs to be put in, and this activation energy drives the reactants from a stable state to a highly energetically unstable transition state to a more stable state that is lower in energy (see: reaction coordinate). The reactants are usually complex molecules that are broken into simpler products. The entire reaction is usually catabolic. The release of energy (called Gibbs free energy) is negative (i.e. −ΔG) because energy is released from the reactants to the products. An endergonic reaction is an anabolic chemical reaction that consumes energy. It is the opposite of an exergonic reaction. It has a positive ΔG because it takes more energy to break the bonds of the reactant than the energy of the products offer, i.e. the products have weaker bonds than the reactants. Thus, endergonic reactions are thermodynamically unfavorable. Additionally, endergonic reactions are usually anabolic. The free energy (ΔG) gained or lost in a reaction can be calculated as follows: ΔG = ΔH − TΔS where ∆G = Gibbs free energy, ∆H = enthalpy, T = temperature (in kelvins), and ∆S = entropy. Examples of major bioenergetic processes Glycolysis is the process of breaking down glucose into pyruvate, producing two molecules of ATP (per 1 molecule of glucose) in the process. When a cell has a higher concentration of ATP than ADP (i.e. has a high energy charge), the cell cannot undergo glycolysis, releasing energy from available glucose to perform biological work. Pyruvate is one product of glycolysis, and can be shuttled into other metabolic pathways (gluconeogenesis, etc.) as needed by the cell. Additionally, glycolysis produces reducing equivalents in the form of NADH (nicotinamide adenine dinucleotide), which will ultimately be used to donate electrons to the electron transport chain. Gluconeogenesis is the opposite of glycolysis; when the cell's energy charge is low (the concentration of ADP is higher than that of ATP), the cell must synthesize glucose from carbon- containing biomolecules such as proteins, amino acids, fats, pyruvate, etc. For example, proteins can be broken down into amino acids, and these simpler carbon skeletons are used to build/ synthesize glucose. The citric acid cycle is a process of cellular respiration in which acetyl coenzyme A, synthesized from pyruvate dehydrogenase, is first reacted with oxaloacetate to yield citrate. The remaining eight reactions produce other carbon-containing metabolites. These metabolites are successively oxidized, and the free energy of oxidation is conserved in the form of the reduced coenzymes FADH2 and NADH. These reduced electron carriers can then be re-oxidized when they transfer electrons to the electron transport chain. Ketosis is a metabolic process where the body prioritizes ketone bodies, produced from fat, as its primary fuel source instead of glucose. This shift often occurs when glucose levels are low: during prolonged fasting, strenuous exercise, or specialized diets like ketogenic plans, the body may also adopt ketosis as an efficient alternative for energy production. This metabolic adaptation allows the body to conserve precious glucose for organs that depend on it, like the brain, while utilizing readily available fat stores for fuel. Oxidative phosphorylation and the electron transport chain is the process where reducing equivalents such as NADPH, FADH2 and NADH can be used to donate electrons to a series of redox reactions that take place in electron transport chain complexes. These redox reactions take place in enzyme complexes situated within the mitochondrial membrane. These redox reactions transfer electrons "down" the electron transport chain, which is coupled to the proton motive force. This difference in proton concentration between the mitochondrial matrix and inner membrane space is used to drive ATP synthesis via ATP synthase. Photosynthesis, another major bioenergetic process, is the metabolic pathway used by plants in which solar energy is used to synthesize glucose from carbon dioxide and water. This reaction takes place in the chloroplast. After glucose is synthesized, the plant cell can undergo photophosphorylation to produce ATP. Additional information During energy transformations in living systems, order and organization must be compensated by releasing energy which will increase entropy of the surrounding. Organisms are open systems that exchange materials and energy with the environment. They are never at equilibrium with the surrounding. Energy is spent to create and maintain order in the cells, and surplus energy and other simpler by-products are released to create disorder such that there is an increase in entropy of the surrounding. In a reversible process, entropy remains constant where as in an irreversible process (more common to real-world scenarios), entropy tends to increase. During phase changes (from solid to liquid, or to gas), entropy increases because the number of possible arrangements of particles increases. If ∆G<0, the chemical reaction is spontaneous and favourable in that direction. If ∆G=0, the reactants and products of chemical reaction are at equilibrium. If ∆G>0, the chemical reaction is non-spontaneous and unfavorable in that direction. ∆G is not an indicator for velocity or rate of chemical reaction at which equilibrium is reached. It depends on amount of enzyme and energy activation. Reaction coupling Is the linkage of chemical reactions in a way that the product of one reaction becomes the substrate of another reaction. This allows organisms to utilize energy and resources efficiently. For example, in cellular respiration, energy released by the breakdown of glucose is coupled in the synthesis of ATP. Cotransport In August 1960, Robert K. Crane presented for the first time his discovery of the sodium-glucose cotransport as the mechanism for intestinal glucose absorption. Crane's discovery of cotransport was the first ever proposal of flux coupling in biology and was the most important event concerning carbohydrate absorption in the 20th century. Chemiosmotic theory One of the major triumphs of bioenergetics is Peter D. Mitchell's chemiosmotic theory of how protons in aqueous solution function in the production of ATP in cell organelles such as mitochondria. This work earned Mitchell the 1978 Nobel Prize for Chemistry. Other cellular sources of ATP such as glycolysis were understood first, but such processes for direct coupling of enzyme activity to ATP production are not the major source of useful chemical energy in most cells. Chemiosmotic coupling is the major energy producing process in most cells, being utilized in chloroplasts and several single celled organisms in addition to mitochondria. Binding Change Mechanism The binding change mechanism, proposed by Paul Boyer and John E. Walker, who were awarded the Nobel Prize in Chemistry in 1997, suggests that ATP synthesis is linked to a conformational change in ATP synthase. This change is triggered by the rotation of the gamma subunit. ATP synthesis can be achieved through several mechanisms. The first mechanism postulates that the free energy of the proton gradient is utilized to alter the conformation of polypeptide molecules in the ATP synthesis active centers. The second mechanism suggests that the change in the conformational state is also produced by the transformation of mechanical energy into chemical energy using biological mechanoemission. Energy balance Energy homeostasis is the homeostatic control of energy balance – the difference between energy obtained through food consumption and energy expenditure – in living systems.

Sex in space

The conditions governing sex in space (intercourse, conception and procreation while weightless) have become a necessary study due to plans for long-duration space missions, as well as the future potential accommodation of sexual partners aboard the International Space Station (ISS). Issues explored include disrupted circadian rhythms, radiation, isolation, stress, and the physical acts of intercourse in zero or minimal gravity. Sex in space is a part of space sexology. Overview Human sexual activity in the weightlessness of outer space presents difficulties due to Newton's third law. According to the law, if the couple remain attached, their movements will counter each other. Consequently, their actions will not change their velocity unless they are affected by another, unattached, object. Some difficulty could occur due to drifting into other objects. If the couple have a combined velocity relative to other objects, collisions could occur. The discussion of sex in space has also raised the issue of conception and pregnancy in space. , with NASA planning lunar outposts and possibly long-duration missions, the topic has taken a respectable place in life sciences. Despite this, some researchers have argued that national and private space agencies have yet to develop any concrete research and plans to address human sexuality in space. Dubé and colleagues (2021) proposed that NASA should embrace the discipline of space sexology by integrating sex research into their Human Research Program. Santaguida and colleagues (2022) have further argued that space agencies and private companies should invest in this discipline to address the potential for sexual harassment and assault in space contexts. Physiological issues Numerous physiological changes have been noted during spaceflight, many of which may affect sex and procreation, notably circulation and the flow of blood within the body. Such potential effects would likely be caused by a culmination of factors, including gravitational changes, planetary and space radiation, noise, vibration, social isolation, disrupted circadian rhythms, or mental and physical stress. Gravity and microgravity The primary issue to be considered in off-Earth reproduction is the lack of gravitational acceleration. Life on Earth, and thus the reproductive and ontogenetic processes of all life, evolved under the constant influence of the Earth's 1g gravitational field. It is important to study how space environment affects critical phases of mammalian reproduction and development, as well as the events surrounding fertilization, embryogenesis, pregnancy, birth, postnatal maturation, and parental care. Studies conducted on rats revealed that, although the fetus developed properly once exposed to normal gravity, rats raised in microgravity lacked the ability to right themselves. Another study examined mouse embryo fertilization in microgravity. Although this resulted in healthy mice, once implanted at normal gravity, the fertilization rate was lower for the embryos fertilized in microgravity. , no mice or rats had developed while in microgravity throughout the entire life cycle. In 2006, American novelist Vanna Bonta invented the 2suit, a garment designed to facilitate sex in weightless environments such as outer space, or on planets with low gravity. The 2suit was made of a lightweight fabric, with a Velcro-lined exterior, which would enable two people to securely embrace. However, Bonta stressed that the 2suit was versatile, and was not intended for the sole purpose of sex. Functionality testing was conducted in 2008 by Bonta aboard G-Force One, a low gravity simulator. It took eight attempts for the two test participants (Bonta and her husband) to successfully embrace one another. According to science author Mark Thompson, the 2suit was cumbersome but moderately successful, and it is not clear whether or not it will have practical value for future space travelers. The 2suit has been covered in the TV series The Universe as well as a 2008 History Channel television documentary. It has also been discussed by online writers. History of attempts NASA has stated that it knows of no intercourse in space. Planned attempts In June 2015, Pornhub announced its plans to make the first pornographic film in space. It launched a crowdfunding campaign to fund the effort, dubbed Sexploration, with the goal of raising $3.4 million in 60 days. The campaign only received pledges for $236,086. If funded, the film would have been slated for a 2016 release, following six months of training for the two performers and six-person crew. Though it claimed to be in talks with multiple private spaceflight carriers, the company declined to name names "for fear that would risk unnecessary fallout" from the carriers. A Space.com article about the campaign mentioned that in 2008, Virgin Galactic received and rejected a $1 million offer from an undisclosed party to shoot a sex film on board SpaceShipTwo. Adult film actress CoCo Brown had begun certifying for a co-pilot seat in the XCOR Lynx spaceplane, which would have launched in a suborbital flight in 2016 and spent a short amount of time in zero-gravity. However, XCOR Aerospace declared bankruptcy before ever flying a space tourist. Short of actual space, the adult entertainment production company Private Media Group has filmed a movie called The Uranus Experiment: Part Two where an actual zero-gravity intercourse scene was accomplished with a reduced-gravity aircraft. The filming process was particularly difficult from a technical and logistical standpoint. Budget constraints allowed for only one shot, featuring the actors Sylvia Saint and Nick Lang. In popular culture Science fiction writer and futurist Isaac Asimov, in a 1973 article "Sex in a Spaceship", conjectured what sex would be like in the weightless environment of space, anticipating some of the benefits of engaging in sex in an environment of microgravity. On July 23, 2006, a Sex in Space panel was held at the Space Frontier Foundation's annual conference. Speakers were science journalist-author Laura Woodmansee, who presented her book Sex in Space; Jim Logan, the first graduate of a new aerospace medicine residency program to be hired by NASA's Johnson Space Center in Houston; and Vanna Bonta, an American poet, novelist, and actress who had recently flown in zero gravity and had agreed to an interview for Woodmansee's book. The speakers made presentations that explored "the biological, emotional, and ... physical issues that will confront people moving [off Earth] into the space environment." NBC science journalist Alan Boyle reported on the panel, opening a world discussion of a topic previously considered taboo. "Sex in Space" was the title of an episode of the History Channel documentary television series The Universe in 2008. The globally distributed show was dubbed into foreign languages, opening worldwide discussion about what had previously been avoided as a taboo subject. Sex in space became a topic of discussion for the long-term survival of the human species, colonization of other planets, inspired songs, and humanized reasons for space exploration. The idea of sex in space appears frequently in science fiction. Arthur C. Clarke claimed to first address it in his 1973 novel Rendezvous with Rama. In the pilot episode of the Expanse, 'Dulcinea''', a scene was shown where the first officer of the ice hauler ship, the Canterbury, was having sexual intercourse with the ship's navigator in zero gravity. The intercourse was met with a sudden interruption when the ship resumed thrust, slamming them both to the bunk bed with the acceleration.

Enculturation

Enculturation is the process by which people learn the dynamics of their surrounding culture and acquire values and norms appropriate or necessary to that culture and its worldviews. Definition and history of research The term enculturation was used first by sociologist of science Harry Collins to describe one of the models whereby scientific knowledge is communicated among scientists, and is contrasted with the 'algorithmic' mode of communication. The ingredients discussed by Collins for enculturation are Learning by Immersion: whereby aspiring scientists learn by engaging in the daily activities of the laboratory, interacting with other scientists, and participating in experiments and discussions. Tacit Knowledge: highlighting the importance of tacit knowledge—knowledge that is not easily codified or written down but is acquired through experience and practice. Socialization: where individuals learn the social norms, values, and behaviours expected within the scientific community. Language and Discourse: Scientists must become fluent in the terminology, theoretical frameworks, and modes of argumentation specific to their discipline. Community Membership: recognition of the individual as a legitimate member of the scientific community. The problem tackled in the article of Harry Collins was the early experiments for the detection of gravitational waves. Enculturation is mostly studied in sociology and anthropology. The influences that limit, direct, or shape the individual (whether deliberately or not) include parents, other adults, and peers. If successful, enculturation results in competence in the language, values, and rituals of the culture. Growing up, everyone goes through their own version of enculturation. Enculturation helps form an individual into an acceptable citizen. Culture impacts everything that an individual does, regardless of whether they know about it. Enculturation is a deep-rooted process that binds together individuals. Even as a culture undergoes changes, elements such as central convictions, values, perspectives, and young raising practices remain similar. Enculturation paves way for tolerance which is highly needed for peaceful co-habitance. The process of enculturation, most commonly discussed in the field of anthropology, is closely related to socialization, a concept central to the field of sociology. Both roughly describe the adaptation of an individual into social groups by absorbing the ideas, beliefs and practices surrounding them. In some disciplines, socialization refers to the deliberate shaping of the individual. As such, the term may cover both deliberate and informal enculturation. The process of learning and absorbing culture need not be social, direct or conscious. Cultural transmission can occur in various forms, though the most common social methods include observing other individuals, being taught or being instructed. Less obvious mechanisms include learning one's culture from the media, the information environment and various social technologies, which can lead to cultural transmission and adaptation across societies. A good example of this is the diffusion of hip-hop culture into states and communities beyond its American origins. Enculturation has often been studied in the context of non-immigrant African Americans. Conrad Phillip Kottak (in Window on Humanity) writes: Enculturation is referred to as acculturation in some academic literature. However, more recent literature has signalled a difference in meaning between the two. Whereas enculturation describes the process of learning one's own culture, acculturation denotes learning a different culture, for example, that of a host. The latter can be linked to ideas of a culture shock, which describes an emotionally-jarring disconnect between one's old and new culture cues. Famously, the sociologist Talcott Parsons once described children as "barbarians" of a sort, since they are fundamentally uncultured. How enculturation occurs When minorities come into the U.S., these people might fully associate with their racial legacy prior to taking part in processing enculturation. Enculturation can happen in several ways. Direct education implies that your family, instructors, or different individuals from the general public unequivocally show you certain convictions, esteems, or anticipated standards of conduct. Parents may play a vital role in teaching their children standard behavior for their culture, including table manners and some aspects of polite social interactions. Strict familial and societal teaching, which often uses different forms of positive and negative reinforcement to shape behavior, can lead a person to adhere closely to their religious convictions and customs. Schools also provide a formal setting to learn national values, such as honoring a country's flag, national anthem, and other significant patriotic symbols. Participatory learning occurs as individuals take an active role of interacting with their environment and culture. Through their own engagement in meaningful activities, they learn socio-cultural norms for their area and may adopt related qualities and values. For example, if your school organizes an outing to gather trash at a public park, this action assists with ingraining the upsides of regard for nature and ecological protection. Strict customs frequently stress participatory learning - for example, kids who take part in the singing of psalms during Christmas will assimilate the qualities and practices of the occasion. Observational learning is when knowledge is gained essentially by noticing and emulating others. As much as an individual related to a model accepts that emulating the model will prompt good results and feels that one is fit for mimicking the way of behaving, learning can happen with no unequivocal instruction. For example, a youngster who is sufficiently fortunate to be brought into the world by guardians in a caring relationship will figure out how to be tender and mindful in their future connections.

Technology and society

Technology, society and life or technology and culture refers to the inter-dependency, co-dependence, co-influence, and co-production of technology and society upon one another. Evidence for this synergy has been found since humanity first started using simple tools. The inter-relationship has continued as modern technologies such as the printing press and computers have helped shape society. The first scientific approach to this relationship occurred with the development of tektology, the "science of organization", in early twentieth century Imperial Russia. In modern academia, the interdisciplinary study of the mutual impacts of science, technology, and society, is called science and technology studies. The simplest form of technology is the development and use of basic tools. The prehistoric discovery of how to control fire and the later Neolithic Revolution increased the available sources of food, and the invention of the wheel helped humans to travel in and control their environment. Developments in historic times have lessened physical barriers to communication and allowed humans to interact freely on a global scale, such as the printing press, telephone, and Internet. Technology has developed advanced economies, such as the modern global economy, and has led to the rise of a leisure class. Many technological processes produce by-products known as pollution, and deplete natural resources to the detriment of Earth's environment. Innovations influence the values of society and raise new questions in the ethics of technology. Examples include the rise of the notion of efficiency in terms of human productivity, and the challenges of bioethics. Philosophical debates have arisen over the use of technology, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar reactionary movements criticize the pervasiveness of technology, arguing that it harms the environment and alienates people. However, proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition. Pre-historical The importance of stone tools, circa 2.5 million years ago, is considered fundamental in the human development in the hunting hypothesis. Primatologist, Richard Wrangham, theorizes that the control of fire by early humans and the associated development of cooking was the spark that radically changed human evolution. Texts such as Guns, Germs, and Steel suggest that early advances in plant agriculture and husbandry fundamentally shifted the way that collective groups of individuals, and eventually societies, developed. Modern examples and effects Technology has taken a large role in society and day-to-day life. When societies know more about the development in a technology, they become able to take advantage of it. When an innovation achieves a certain point after it has been presented and promoted, this technology becomes part of the society. The use of technology in education provides students with technology literacy, information literacy, capacity for life-long learning, and other skills necessary for the 21st century workplace. Digital technology has entered each process and activity made by the social system. In fact, it constructed another worldwide communication system in addition to its origin. A 1982 study by The New York Times described a technology assessment study by the Institute for the Future, "peering into the future of an electronic world." The study focused on the emerging videotex industry, formed by the marriage of two older technologies, communications, and computing. It estimated that 40 percent of American households will have two-way videotex service by the end of the century. By comparison, it took television 16 years to penetrate 90 percent of households from the time commercial service was begun. Since the creation of computers achieved an entire better approach to transmit and store data. Digital technology became commonly used for downloading music and watching movies at home either by DVDs or purchasing it online. Digital music records are not quite the same as traditional recording media. Obviously, because digital ones are reproducible, portable and free. Around the globe many schools have implemented educational technology in primary schools, universities and colleges. According to the statistics, in the early beginnings of 1990s the use of Internet in schools was, on average, 2–3%. Continuously, by the end of 1990s the evolution of technology increases rapidly and reaches to 60%, and by the year of 2008 nearly 100% of schools use Internet on educational form. According to ISTE researchers, technological improvements can lead to numerous achievements in classrooms. E-learning system, collaboration of students on project based learning, and technological skills for future results in motivation of students. Although these previous examples only show a few of the positive aspects of technology in society, there are negative side effects as well. Within this virtual realm, social media platforms such as Instagram, Facebook, and Snapchat have altered the way Generation Y culture is understanding the world and thus how they view themselves. In recent years, there has been more research on the development of social media depression in users of sites like these. "Facebook Depression" is when users are so affected by their friends' posts and lives that their own jealousy depletes their sense of self-worth. They compare themselves to the posts made by their peers and feel unworthy or monotonous because they feel like their lives are not nearly as exciting as the lives of others. Technology has a serious effect on youth's health. The overuse of technology is said to be associated with sleep deprivation which is linked to obesity and poor academic performance in the lives of adolescents. Economics and technological development In ancient history, economics began when spontaneous exchange of goods and services was replaced over time by deliberate trade structures. Makers of arrowheads, for example, might have realized they could do better by concentrating on making arrowheads and barter for other needs. Regardless of goods and services bartered, some amount of technology was involved—if no more than in the making of shell and bead jewelry. Even the shaman's potions and sacred objects can be said to have involved some technology. So, from the very beginnings, technology can be said to have spurred the development of more elaborate economies. Technology is seen as primary source in economic development. Technology advancement and economic growth are related to each other. The level of technology is important to determine the economic growth. It is the technological process which keeps the economy moving. In the modern world, superior technologies, resources, geography, and history give rise to robust economies; and in a well-functioning, robust economy, economic excess naturally flows into greater use of technology. Moreover, because technology is such an inseparable part of human society, especially in its economic aspects, funding sources for (new) technological endeavors are virtually illimitable. However, while in the beginning, technological investment involved little more than the time, efforts, and skills of one or a few men, today, such investment may involve the collective labor and skills of many millions. Most recently, because of the COVID-19 pandemic, the proportion of firms employing advanced digital technology in their operations expanded dramatically. It was found that firms that adopted technology were better prepared to deal with the pandemic's disruptions. Adaptation strategies in the form of remote working, 3D printing, and the use of big data analytics and AI to plan activities to adapt to the pandemic were able to ensure positive job growth. Funding Consequently, the sources of funding for large technological efforts have dramatically narrowed, since few have ready access to the collective labor of a whole society, or even a large part. It is conventional to divide up funding sources into governmental (involving whole, or nearly whole, social enterprises) and private (involving more limited, but generally more sharply focused) business or individual enterprises. Government funding for new technology The government is a major contributor to the development of new technology in many ways. In the United States alone, many government agencies specifically invest billions of dollars in new technology. In 1980, the UK government invested just over six million pounds in a four-year program, later extended to six years, called the Microelectronics Education Programme (MEP), which was intended to give every school in Britain at least one computer, software, training materials, and extensive teacher training. Similar programs have been instituted by governments around the world. Technology has frequently been driven by the military, with many modern applications developed for the military before they were adapted for civilian use. However, this has always been a two-way flow, with industry often developing and adopting a technology only later adopted by the military. Entire government agencies are specifically dedicated to research, such as America's National Science Foundation, the United Kingdom's scientific research institutes, America's Small Business Innovative Research effort. Many other government agencies dedicate a major portion of their budget to research and development. Private funding Research and development is one of the smallest areas of investments made by corporations toward new and innovative technology. Many foundations and other nonprofit organizations contribute to the development of technology. In the OECD, about two-thirds of research and development in scientific and technical fields is carried out by industry, and 98 percent and 10 percent, respectively, by universities and government. But in poorer countries such as Portugal and Mexico the industry contribution is significantly less. The U.S. government spends more than other countries on military research and development, although the proportion has fallen from about 30 percent in the 1980s to less than 10 percent. The 2009 founding of Kickstarter allows individuals to receive funding via crowdsourcing for many technology related products including both new physical creations as well as documentaries, films, and web-series that focus on technology management. This circumvents the corporate or government oversight most inventors and artists struggle against but leaves the accountability of the project completely with the individual receiving the funds. Other economic considerations Appropriate technology, sometimes called "intermediate" technology, more of an economics concern, refers to compromises between central and expensive technologies of developed nations and those that developing nations find most effective to deploy given an excess of labour and scarcity of cash. Persuasion technology: In economics, definitions or assumptions of progress or growth are often related to one or more assumptions about technology's economic influence. Challenging prevailing assumptions about technology and its usefulness has led to alternative ideas like uneconomic growth or measuring well-being. These, and economics itself, can often be described as technologies, specifically, as persuasion technology. Technocapitalism Technological diffusion Technology acceptance model Technology life cycle Technology transfer Relation to science The relationship between science and technology can be complex.  Science may drive technological development, by generating demand for new instruments to address a scientific question, or by illustrating technical possibilities previously unconsidered.  An environment of encouraged science will also produce scientists and engineers, and technical schools, which encourages innovation and entrepreneurship that are capable of taking advantage of the existing science.  In fact, it is recognized that "innovators, like scientists, do require access to technical information and ideas" and "must know enough to recognize useful knowledge when they see it."  Science spillover also contributes to greater technological diffusion.  Having a strong policy contributing to basic science allows a country to have access to a strong a knowledge base that will allow them to be "ready to exploit unforeseen developments in technology," when needed in times of crisis. For most of human history, technological improvements were arrived at by chance, trial and error, or spontaneous inspiration.  Stokes referred to these innovators as improvers of technology'…who knew no science and would not have been helped by it if they had."  This idea is supported by Diamond who further indicated that these individuals are "more likely to achieve a breakthrough if [they do] not hold the currently dominant theory in too high regard." Research and development directed towards immediate technical application is a relatively recent occurrence, arising with the Industrial Revolution and becoming commonplace in the 20th century.  In addition, there are examples of economies that do not emphasize science research that have been shown to be technological leaders despite this.  For example, the United States relied on the scientific output of Europe in the early 20th century, though it was regarded as a leader in innovation. Another example is the technological advancement of Japan in the latter part of the same century, which emphasized more applied science (directly applicable to technology). Though the link between science and technology has need for more clarity, what is known is that a society without sufficient building blocks to encourage this link are critical.  A nation without emphasis on science is likely to eventually stagnate technologically and risk losing competitive advantage.  The most critical areas for focus by policymakers are discouraging too many protections on job security, leading to less mobility of the workforce, encouraging the reliable availability of sufficient low-cost capital for investment in R&D, by favorable economic and tax policies, and supporting higher education in the sciences to produce scientists and engineers. Sociological factors and effects Values The implementation of technology influences the values of a society by changing expectations and realities. The implementation of technology is also influenced by values. There are (at least) three major, interrelated values that inform, and are informed by, technological innovations: Mechanistic world view: Viewing the universe as a collection of parts (like a machine), that can be individually analyzed and understood. This is a form of reductionism that is rare nowadays. However, the "neo-mechanistic world view" holds that nothing in the universe cannot be understood by the human intellect. Also, while all things are greater than the sum of their parts (e.g., even if we consider nothing more than the information involved in their combination), in principle, even this excess must eventually be understood by human intelligence. That is, no divine or vital principle or essence is involved. Efficiency: A value, originally applied only to machines, but now applied to all aspects of society, so that each element is expected to attain a higher and higher percentage of its maximal possible performance, output, or ability. Social progress: The belief that there is such a thing as social progress, and that, in the main, it is beneficent. Before the Industrial Revolution, and the subsequent explosion of technology, almost all societies believed in a cyclical theory of social movement and, indeed, of all history and the universe. This was, obviously, based on the cyclicity of the seasons, and an agricultural economy's and society's strong ties to that cyclicity. Since much of the world is closer to their agricultural roots, they are still much more amenable to cyclicity than progress in history. This may be seen, for example, in Prabhat Rainjan Sarkar's modern social cycles theory. For a more westernized version of social cyclicity, see Generations: The History of America's Future, 1584 to 2069 (Paperback) by Neil Howe and William Strauss; Harper Perennial; Reprint edition (September 30, 1992); , and subsequent books by these authors. Institutions and groups Technology often enables organizational and bureaucratic group structures that otherwise and heretofore were simply not possible. Examples of this might include: The rise of very large organizations: e.g., governments, the military, health and social welfare institutions, supranational corporations. The commercialization of leisure: sports events, products, etc. (McGinn) The almost instantaneous dispersal of information (especially news) and entertainment around the world. International Technology enables greater knowledge of international issues, values, and cultures. Due mostly to mass transportation and mass media, the world seems to be a much smaller place, due to the following: Globalization of ideas Embeddedness of values Population growth and control Environment Technology can provide understanding of and appreciation for the world around us, enable sustainability and improve environmental conditions but also degrade the environment and facilitate unsustainability. Some polities may conclude that certain technologies' environmental detriments and other risks to outweigh their benefits, especially if or once substitutive technologies have been or can be invented, leading to directed technological phase-outs such as the fossil fuel phase-out and the nuclear fission power phase-out. Most modern technological processes produce unwanted byproducts in addition to the desired products, which are known as waste and pollution. While material waste is often re-used in industrial processes, many processes lead to a release into the environment with negative environmental side effects, such as pollution and lack of sustainability. Development and technologies' implications Some technologies are designed specifically with the environment in mind, but most are designed first for financial or economic effects such as the free market's profit motive. The effects of a specific technology is often not only dependent on how it is used – e.g. its usage context – but also predetermined by the technology's design or characteristics, as in the theory of "the medium is the message" which relates to media-technologies in specific. In many cases, such predetermined or built-in implications may vary depending on factors of contextual contemporary conditions such as human biology, international relations and socioeconomics. However, many technologies may be harmful to the environment only when used in specific contexts or for specific purposes that not necessarily result from the nature of the technology. Values Historically, from the perspective of economic agent-centered responsibility, an increased, as of 2021 commonly theoretic and informal, value of healthy environments and more efficient productive processes may be the result of an increase in the wealth of society. Once people are able to provide for their basic needs, they can – and are often facilitated to – not only afford more environmentally destructive products and services, but could often also be able to put an – e.g. individual morality-motivated – effort into valuing less tangible goods such as clean air and water if product-, alternatives-, consequences- and services-information are adequate. From the perspective of systems science and cybernetics, economies (systems) have economic actors and sectors make decisions based upon a range of system-internal factors with structures – or sometimes forms of leveraging existing structures – that lead to other outcomes being the result of other architectures – or systems-level configurations of the existing designs – which are considered to be possible in the sense that such could be modeled, tested, priorly assessed, developed and studied. Negative effects on the environment The effects of technology on the environment are both obvious and subtle. The more obvious effects include the depletion of nonrenewable natural resources (such as petroleum, coal, ores), and the added pollution of air, water, and land. The more subtle effects may include long-term effects (e.g. global warming, deforestation, natural habitat destruction, coastal wetland loss.) Pollution and energy requirements Each wave of technology creates a set of waste previously unknown by humans: toxic waste, radioactive waste, electronic waste, plastic waste, space waste. Electronic waste creates direct environmental impacts through the production and maintaining the infrastructure necessary for using technology and indirect impacts by breaking barriers for global interaction through the use of information and communications technology. Certain usages of information technology and infrastructure maintenance consume energy that contributes global warming. This includes software-designs such as international cryptocurrencies and most hardware powered by nonrenewable sources. One of the main problems is the lack of societal decision-making processes – such as the contemporary economy and politics – that lead to sufficient implementation of existing as well as potential efficient ways to remove, recycle and prevent these pollutants on a large scale expediently. Digital technologies, however, are important in achieving the green transition and specifically, the SDGs and European Green Deal's environmental targets. Emerging digital technologies, if correctly applied, have the potential to play a critical role in addressing environmental issues. A few examples are: smart city mobility, precision agriculture, sustainable supply chains, environmental monitoring, and catastrophe prediction. Construction and shaping Choice Society also controls technology through the choices it makes. These choices not only include consumer demands; they also include: the channels of distribution, how do products go from raw materials to consumption to disposal; the cultural beliefs regarding style, freedom of choice, consumerism, materialism, etc.; the economic values we place on the environment, individual wealth, government control, capitalism, etc. According to Williams and Edge, the construction and shaping of technology includes the concept of choice (and not necessarily conscious choice). Choice is inherent in both the design of individual artifacts and systems, and in the making of those artifacts and systems. The idea here is that a single technology may not emerge from the unfolding of a predetermined logic or a single determinant, technology could be a garden of forking paths, with different paths potentially leading to different technological outcomes. This is a position that has been developed in detail by Judy Wajcman. Therefore, choices could have differing implications for society and for particular social groups. Autonomous technology In one line of thought, technology develops autonomously, in other words, technology seems to feed on itself, moving forward with a force irresistible by humans. To these individuals, technology is "inherently dynamic and self-augmenting." Jacques Ellul is one proponent of the irresistibleness of technology to humans. He espouses the idea that humanity cannot resist the temptation of expanding our knowledge and our technological abilities. However, he does not believe that this seeming autonomy of technology is inherent. But the perceived autonomy is because humans do not adequately consider the responsibility that is inherent in technological processes. Langdon Winner critiques the idea that technological evolution is essentially beyond the control of individuals or society in his book Autonomous Technology. He argues instead that the apparent autonomy of technology is a result of "technological somnambulism," the tendency of people to uncritically and unreflectively embrace and utilize new technologies without regard for their broader social and political effects. In 1980, Mike Cooley published a critique of the automation and computerisation of engineering work under the title "Architect or Bee? The human/technology relationship". The title alludes to a comparison made by Karl Marx, on the issue of the creative achievements of human imaginative power. According to Cooley ""Scientific and technological developments have invariably proved to be double-edged. They produced the beauty of Venice and the hideousness of Chernobyl; the caring therapies of Rontgen's X-rays and the destruction of Hiroshima," Government Individuals rely on governmental assistance to control the side effects and negative consequences of technology. Supposed independence of government. An assumption commonly made about the government is that their governance role is neutral or independent. However, some argue that governing is a political process, so government will be influenced by political winds of influence. In addition, because government provides much of the funding for technological research and development, it has a vested interest in certain outcomes. Other point out that the world's biggest ecological disasters, such as the Aral Sea, Chernobyl, and Lake Karachay have been caused by government projects, which are not accountable to consumers. Liability. One means for controlling technology is to place responsibility for the harm with the agent causing the harm. Government can allow more or less legal liability to fall to the organizations or individuals responsible for damages. Legislation. A source of controversy is the role of industry versus that of government in maintaining a clean environment. While it is generally agreed that industry needs to be held responsible when pollution harms other people, there is disagreement over whether this should be prevented by legislation or civil courts, and whether ecological systems as such should be protected from harm by governments. Recently, the social shaping of technology has had new influence in the fields of e-science and e-social science in the United Kingdom, which has made centers focusing on the social shaping of science and technology a central part of their funding programs.

Transactionalism

Transactionalism is a pragmatic philosophical approach to questions such as: what is the nature of reality; how we know and are known; and how we motivate, maintain, and satisfy our goals for health, money, career, relationships, and a multitude of conditions of life through mutually cooperative social exchange and ecologies. It involves the study and accurate thinking required to plan and utilize one's limited resources in the fundamental mechanics of social exchange or trans-action. To transact is learning to beat the odds or mitigate the common pitfalls involved with living a good and comfortable life by always factoring in the surrounding circumstances of people, places, things and the thinking behind any exchange from work to play. In our complex, ever-changing society with its indifferent marketplace, we cannot thrive without requesting or inviting the help of others and offering help to those around us. To co-create a healthy exchange of value for all involved, we must understand and apply the fundamental mechanics of transaction. [This is not to be confused with the favor or advantage of quid pro quo.] Without cooperative exchange, we resist transacting to survive the unavoidable biological, societal, and environmental threats that can prevent us from comfort and ease in any of the multiple conditions of life we labor to maintain (cf. Hannah Arendt's philosophy of labor, work, and action). In this philosophy, human interactions are best understood as a set of simple to complex transactions. A transaction is a reciprocal and co-constitutive cycle of moves (what to do) and phases (or implemented tactics) aimed at satisfying (or at learning to become fit) in the multiple and interlocking conditions of life including health, work, money, knowledge, education, career, ethics, and more. If we work ourselves to death or ignore accurate thinking about our relationships, without help those conditions of life will eventually threaten our health, career, and money, for example. We must transact to maintain multiple and unavoidable conditions of our lives. A transactionalist approach demands an "un-fractured observation" of life as an organism that is influenced by and is influencing its environment or ecology. By considering the self as an organism inseparable from its environment, hyphenated as "organism-environment," we begin to recognize that any outcome is "determined by prior causes and articulated ends" not merely the intention or the end goal of an individual. This philosophical approach has correlation to Hannah Arendt's notion of human being as "political animal" ("Zoon Politikon") that should attend to the "labor, work, and action" beyond merely articulating an aspiration or a goal. It is critical that an organism-environment keep in mind how "consequences and outcomes" determine the satisfaction of any human endeavor. We must take into account that we, as a human being in transaction, are embedded in and constituted by not only our intentions, but simultaneously by the specific circumstances of our biology, our narratives in exchange, and the social situation that includes tangible resources like tools and settings, intangible resources like time and meaning, and the human resources of other people and their personalities and roles within a transaction or social exchange. Beyond our conscious awareness, three aspects of experience — the observer, the process of observing, and the thing observed in a situation— are all "affected by whatever merits or defects [the organism or environment] may prove to have when it is judged". A transactionalist holds that all human acts, including learning, are best understood as "entities" within a larger, often under-examined, transactional whole. The transactional whole is shaped by our health as an organism as well as the health of others (e.g., our biology as a living organisms), for example. Transactional competence is shaped by language and communication with others (e.g.,linguistic narratives). It is shaped and affected by one's fitness in satisfying an ethical exchange of business or education in certain conditions of life, such as reputation, politics (small and large), and ethics—how we treat one another or regulate our behavior and feelings. Human satisfaction is shaped first and foremost by our body's state of wellness or disease, which is inescapably linked to the ecology, shared and/or invented norms and values, and the fitness of our ability to understand the mechanics of trans-acting. We must make real the conditions and accept the consequences of what it takes to live a satisfying life in an ever-changing body and world. Transactionalism functions as a means of "controlled inquiry" into the complex nature and interactions of daily life. Overview In their 1949 book Knowing and the Known, transactionalists John Dewey and Arthur Bentley explained that they were "willing under hypothesis to treat all [human] behavings, including [their] most advanced knowings, as activities not of [them]self alone, nor even as primarily [theirs], but as processes of the full situation of organism-environment." John Dewey used the term "trans-action" to "describe the process of knowing as something that involves the full situation of organism-environment, not a mere inter-action between two independent entities, e.g., the observer and the object observed." A "trans-action" (or simply a "transaction") rests upon the recognition that subject (the observer) and object (the observed) are inseparable; "Instead, observer and observed are held in close organization. Nor is there any radical separation between that which is named and the naming." A knower (as "subject") and what they know (as "object" that may be human, tangible, or intangible) are inseparable and must be understood as inseparable to live a truly satisfying life. Dewey and Bentley distinguished the "trans-actional" point of view (as opposed to a "self-actional" or "inter-actional" one) in their preface: The transactional is in fact that point of view which systematically proceeds upon the ground that knowing is co-operative and as such is integral with communication. By its own processes it is allied with the postulational. It demands that statements be made as descriptions of events in terms of durations in time and areas in space. It excludes assertions of fixity and attempts to impose them. It installs openness and flexibility in the very process of knowing. It treats knowledge as itself inquiry—as a goal within inquiry, not as a terminus outside or beyond inquiry.The metaphysics and epistemology of living a satisfactory life begins with the hypothesis that man is an "organism-environment" solving problems in and, through a necessary exchange with others. Therefore, attention must always be paid to organizing acts as aspects or entities within a reciprocal, co-constitutive, and ethical exchange, whether it be in co-operative buying and selling; teaching and learning; marital trans-actions; or in any social situation where human beings engage one another. Definition Stemming from the Latin transigere ("to drive through", "to accomplish"), the root word "transaction" is not restricted to (or to be collapsed with) the economic sense of buying and selling or merely associated with a financial transaction. A much larger field of exchange is employed and summoned up here; such as, "any sort of social interaction, such as verbal communication, eye contact, or touch. A 'stroke' [of one's hand] is an act of recognition of a transaction" as described in psychological transactional analysis It not only examines exchanges, or "transactions," between borrower and lender, but encompasses any transaction involving people and objects including "borrowing-lending, buying-selling, writing-reading, parent-child, and husband-wife [or partners in a civil or marital union]." A transaction, then is "a creative act, engaged in by one who, by virtue of [their] participation in the act – of which [they are] always an aspect, never an entity – together with the other participants, be they human or otherwise environmental, becomes in the process modified" by and through exchange with others. Background Main contributors While John Dewey is viewed by many transactionalists as its principal architect, social anthropologist Fredrik Barth was among the first to articulate the concept as it is understood in contemporary study. Political scientists Karl W. Deutsch and Ben Rosamond have also written on the subject. In 1949, Dewey and Bentley offered that their sophisticated pragmatic approach starts from the perception of "man" as an organism that is always transacting within its environment; that it is sensible to think of our selves as an organism-environment seeking to fulfill multiple necessary conditions of life "together-at-once". It is a philosophy purposefully designed to correct the "fragmentation of experience" found in the segmented approaches of Subjectivism, Constructivism, Objectivism (Ayn Rand), and Skepticism.[1] Each of these approaches are aspects of problem-solving used by the transactionalist to examine the invention, construction of a narrative presentation, the objective work or activity that must happen, and the deconstruction of a transaction to fully observe and assess the consequences and outcomes of any transaction—from simply to complex—in the process of living a good and satisfying life. Dewey asserted that human life is not actually organized into separate entities, as if the mind (its sense of emotion, feeling, invention, imagination, or judgment) and the world outside it (natural and manufactured goods, social roles and institutions including the family, government, or media) are irreconcilable, leading to the question "How does the mind know the world?" Transactionalist analysis is a core paradigm advanced by social psychologist Eric Berne in his book Games People Play, in which an analyst seeks to understand an individual as "embedded and integrated" in an ever-evolving world of situations, actors, and exchange. The situational orientation of transactionalist problem-solving has been applied to a vast array of academic and professional discourses including educational philosophy in the humanities; social psychology, political science, and political anthropology in the social sciences; and occupational science in the health sciences; cognitive science, zoology, and quantum mechanics in the natural sciences; as well as the development of a transactional competence in leadership-as-practice in business management. Historical antecedents Galileo refused to seek the causes of the behavior of physical phenomena in the phenomena alone and sought the causes in the conditions under which the phenomena occur.The evolution of philosophy from aristotelian thought to galilean thinking shifts the focus from behavior to the context of the behavior in problem-solving. The writing of John Dewey and Arthur Bentley in Knowing and the Known offers a dense primer into transactionalism, but its historical antecedents date back to Polybius and Galileo. Trevor J. Phillips (1927–2016), American professor emeritus in educational foundations and inquiry at Bowling Green State University from 1963 to 1996, wrote a comprehensive thesis documenting the historical, philosophical, psychological, and educational development of transactionalism in his 1966 dissertation "Transactionalism: An Historical and Interpretive Study" published in 2013 by business education called Influence Ecology. Phillips traced transactionalism's philosophical roots to Greek historians such as Polybius and Plato as well as 17th century polymath Galileo—considered the architect of the scientific revolution and René Descartes—considered the architect of modern western philosophy. Galileo's contributions to the scientific revolution rested on a transactionalist understanding from which he argued Aristotelian physics was in error, as he wrote in Dialogue Concerning the Two Chief World Systems (1632):"[I]f it is denied that circular motion is peculiar to celestial bodies, and affirmed to belong to all naturally movable bodies, then one must choose one of two necessary consequences. Either the attributes of generable-ingenerable, alterable-inalterable, divisible-indivisible, etc., suit equally and commonly all world bodies – as much the celestial as the elemental – or Aristotle has wrongly and erroneously deduced, from circular motion, those attributes which he has assigned to celestial bodiesTransactionalism abandons self-actional and inter-actional beliefs or suppositions that lead to incomplete problem-solving. In a world of subjective and objective information, co-operative exchange creates value in learning and becomes the foundation of a transactional competence based on recurrent inquiry into how objects (including people) behave as situations constantly evolve. Galileo deviated from the then-current Aristotelian thinking, which was defined by mere interactions rather than co-constitutive transacting among persons with different interests or among persons who may be solving competing intentions or conditions of life. Modern antecedents Trevor Phillips also outlined the philosophy's more recent developments found in the American philosophical works of Charles Sanders Peirce, sociologist George Herbert Mead (symbolic interactionism), pragmatist philosophers William James and John Dewey, and political scientist Arthur Bentley. Several sources credit anthropologist Fredrik Barth as the scholar first to apply the term 'transactionalism" in 1959. In a critique of structural functionalism, Barth offered a new interpretation of culture that did not portray an overly cohesive picture of society without attending to the "roles, relationships, decisions, and innovations of the individual." Humans are transacting with one another at the multiple levels of individual, group, and environment. Barth's study appears to not fully articulate how this is happening all-at-once as opposed to as-if they were separate entities interacting independently ("interactional"):[T]he "environment" of any ethnic group is not only defined by natural conditions, but also by the presence and activities of other ethnic groups on which it depends. Each group exploits only a section of the total environment, and leaves large parts of it open for other groups to exploit.Using examples from the people of the Swat district of North Pakistan and, later, in 1966, organization taking place among Norwegian fishermen, Barth set out to demonstrate that social forms like kinship groups, economic institutions, and political alliances are generated by the actions and strategies of the individuals who deploy organized acts against (or within) a context of social constraints. "By observing how people interact with each other [through experience], an insight could be gained into the nature of the competition, values[,] and principles that govern individuals' choices." Utilized as a "theoretical orientation" in Norwegian anthropology, describes transactionalism as "process analysis" (prosessanalyse) categorized as a sociological theory or method. Though criticized for paying insufficient attention to cultural constraints on individualism, Barth's orientation influenced the qualitative method of symbolic interactionism applied throughout the social sciences. Process analysis considers the gradual unfolding of the course of interactions and events as key to understanding social situations. In other words, the transactional whole of a situation is not readily apparent at the level of individuals. At that level, an individual operates in a self-actional manner when much larger forces of sociality, history, biology, and culture are, all-at-once, at work on an individual as part of a global dynamic. Humans can never exist outside this dynamic current, as if they are operating the system in some self-actional or interactional way. Barth's approach reflects the co-constitutive nature of living in ever-evolving circumstances. 21st century applications Transactional leadership (LAP) In a new model of organizational management known as "leadership-as-practice" (LAP), Dewey and Bentley's Knowing and the Known categories of action—namely, self-action, inter-action, and trans-action–brings transactionalism into the corporate culture. A transactional leadership practice is defined by its "trans-actors" who "enact new and unfolding meanings in on-going trans-actions." Actors operating "together-at-once" in a transaction is contrasted with the older model of leadership defined by the practices of actors operating in self-actional or inter-actional way. In the former models, often the actors and situations remain unchanged by leadership interventions over time because the actors and situations remain unchanged. In leadership-as-practice, Joseph A. Raelin distinguishes between a "practice" that extends and amplifies the meaning of work and its value vs. "practices" that are habitual and sequential activities evoked to simplify everyday routines. A transactional approach—leadership-as-practice—focuses attention on "existing entanglements, complexities, processes, [while also] distinguishing problems in order to coordinate roles, acts, and practices within a group or organization." Said another way, "trans-action attends to emergent becoming"—a kind of seeing together--"rather than substantive being" among the actors involved. Transactional competence Modern architects of the philosophy, John Patterson and Kirkland Tibbels, co-founders of Influence Ecology, acquired, edited, and published Phillips' dissertation (as is) in 2013. With a foreword written by Tibbels, a hardback and Kindle version was published under the title Transactionalism: An Historical and Interpretive Study (2013). The monograph is an account of how human phenomena came to be viewed less as the behavior of static and/or mutually isolated entities, and more as dynamic aspects of events in the process of problem-solving, and thereby becoming or satisfying, the unavoidable and inescapable conditions of human life. Philosophy Metaphysics: transactional (vs. self-actional or interactional) The transactional view of metaphysics—studying the nature of reality or what is real—deals with the inseparability of what is known and how humans inquire into what is known—both knowing and the known. Since the age of Aristotle, humans have shifted from one paradigm or system of "logic" to another before a transactional metaphysics evolved with a focus that examines and inquires into solving problems first and foremost based on the relationship of man as a biological organism (with a brain and a body) shaped by its environment. In the book Transactionalism (2015), the nature of reality is traced historically from self-action to interaction to transactional competence each as its own age of knowing or episteme. The pre-Galilean age of knowing is defined by self-action "where things [and thereby people] are viewed as acting on their own powers." In Knowing and the Known, Dewey and Bentley wrote, "The epistemologies, logics, psychologies and sociologies [of our day] are still largely [understood] on a self-actional basis." The result of Newtonian physics, interaction marks the second age of knowing; a system marked especially by the "third 'law of motion'—that action and reaction are equal and opposite". The third episteme is transactional competence. With origins in the contributions of Darwin, "man's understandings are finite as opposed to infinite. In the same way, his views, goals, commitments, and beliefs have relative status as opposed to absolute." John Dewey and Arthur Bentley asserted this competence as "the right to see together, extensionally and durationally, much that is talked about conventionally as if it were composed of irreconcilable separates." We tend to avoid considering our actions as part of a dynamic and transactional whole, whether in mundane or complex activities; whether in making an invitation, request, or offer or in the complex management of a program or company. We tend to avoid studying, thinking, and planning our moves and moods for a comprehensive, reciprocal, and co-constitutive—in other words, transactional—whole. A transactional whole includes the organized acts including ideas, narratives, people as resources implementing ideas, services, and products, the things involved, settings, and personalities, all considered in and over time. With this competence, that which acts and is acted upon become united for a moment in a mutual or ethical exchange, where both are reciprocally transformed contradicting "any absolute separation or isolation" often found in the dualistic thinking and categorization of Western thought. Dualistic thinking and categorization often lead to over-simplification of the transactional whole found in the convenient but ineffective resorting to "exclusive classifications." Such classifications tend to exclude and reify man as if he has dominion over his nature or the environment. In his seminal 20th century work Physics and Philosophy, Werner Heisenberg reflects this kind of transactionalist thinking: "What we observe is not nature itself, but nature exposed to our method of questioning." The together-at-once reality of man as organism-environment is often overlooked in the dualistic thinking of even major philosophers like Descartes who is often referenced for his "I think, therefore I am" philosophy. Of a transactionalist approach, Heisenberg writes, "This was a possibility of which Descartes could not have thought, but it makes the sharp separation of the world and I impossible." Dualistic thinking prevents man from thinking. "In the spirit of [Charles Sanders] Peirce, transactionalism substitutes continuity for discontinuity, change and interdependence for separateness." For example, in problem solving, whenever we "insert a name instead of a problem," when words like "soul," "mind," "need," "I.Q." or "trait" are expressed as if real, they have the power to block and distort free inquiry into what is known in fact or as fact in the transactional whole. In the nature of change and being, "that which acts and that which is acted upon" always undergo a reciprocal relationship that is affected by the presence and influence of the other. We as human beings, as part of nature as an organism "integral to (as opposed to separate from, above or outside of) any investigation and inquiry may use a transactionalist approach to expand our personal knowledge so as to solve life's complex problems. The purpose of transactionalism is not to discover what is already there, but for a person to seek and interpret senses, objects, places, positions, or any aspect of transactions between one's Self and one's environment (including objects, other people, and their symbolic interactions) in terms of the aims and desires each one needs and wants to satisfy and fulfill. It is essential that one simultaneously take into account the needs and desires of others in one's environment or ecology to avoid the self-actional or self-empowerment ideology of a rugged and competitive individualism. While other philosophies may discuss similar ethical concerns, this co-constitutive and reciprocal element of problem-solving is central to transactionalism. To put it simply, "to experience is to transact; in point of fact, experience is a transaction of organism-environment." In other words, what is "known" by the knower (or organism) is always filtered and shaped by both internal and external moods and narratives, mirrored in and through our relationships to the physical affordances and constraints in our environment or in specific ecologies. The metaphysics of transactional inquiry is characterized in the pragmatic writing of William James who insists that "single barreled terms," terms like "thought" and "thing," actually stop or block inquiries into what is known and how we know it. Instead, a transactional orientation of 'double-barreledness' or the "interdependence of aspects of experience" must always be considered. James offers his readers insight into the "double-barreledness" of experience with an apt proposition:Is the preciousness of a diamond a quality of the gem [the thing] or is it a feeling in our mind [the thought]? Practically we treat it as both or as either, according to the temporary direction of our thought. The 'experienced' and the 'experiencing,' the 'seen' and the 'seeing,' are, in actuality, only names for a single fact. What is real then, from a transactionist perspective, must be constantly reevaluated relative to man as organism-environment in a co-constitutive and reciprocal dynamic with people, personalities, situations, aims, and given the needs each party seeks to satisfy. Epistemology: truth from inquiry Transactionalists are firmly intolerant of "anything resembling an 'ultimate' truth – or 'absolute' knowledge." Humankind has the propensity to treat the mind and thought or the mind and body as abstractions and this tendency to deny the interrelatedness or coordinated continuity results in misconceptions in learning and inaccurate thinking as humans move and thrive with an ecology. Accurate thinking and learning begins and is constantly developed through action resulting from thought as a repetitive circuit of experience known in psychology as deliberate practice. Educational philosopher Trevor Phillips, now deceased, frames this tendency to falsely organize our perception: "[W]e fail to realize that we can know nothing about things [or ourselves] beyond their significance to us," otherwise we distort our "reality" and treat things we perceive within it, including our bodies or mind, as if concrete thereby "denying the interconnectedness of realities" (plural). Transactionalists suggest that accurate (or inaccurate) thinking is rarely considered an unintended consequence of our propensity for abstractions. When an individual transacts through intelligent or consequential actions circumscribed within the constraints and conditions of her/his environment in a reflexive, repetitive arc of learned experience, there is a "transaction between means and ends" (see reference below). This transactional approach features twin aspects of a larger event rather than merely manipulating the means to an end in our circumstances and situations. For instance, a goal can never be produced by abstraction, by simply thinking about or declaring a promise to produce a result. Nor can it be anticipated or foreseen (an abstraction at best) without a significant "pattern of inquiry," as John Dewey later defined and articulated, into the constraints and conditions that happen and are happening given the interdependence of all the people and objects involved in a simple or complex transaction. The nature of our environment affects all these entities within a transaction. Thus, revealing the limiting and reductive notion of manipulating a psychology around stimulus and response found in Aristotilian or Cartesian thought. A transaction is recognized here as one that occurs between the "means and ends;" in other words, transactional competence is derived from the "distinctions between the how, the what (or subject-matter), and the why (or what for)." This transactional whole constitutes a reciprocal connection and a reflexive arc of learned and lived experience. From a transactional approach one can derive a certain kind of value from one's social exchange. Value in knowing how, what, and why the work done with your mind and body fulfill on the kinds of transactions needed to live a good and satisfying life that functions well with others. Truth from actual inquiry is foundational for organism-environment to define and live by a set of workable ethical values that functions with others. Due to the evolution of psychology about the nature of man, transactionalists also reject the notion of a mind-body split or anything resembling the bifurcation of what they perceive as the circuitry in which our biological stimulus-response exists. Examples transactionalists reject include the self-acting notions of Aristotle who posited that "the soul – the psyche – realized itself in and through the body, and that matter and form were two aspects involved in all existence." Later, the claims of French philosopher René Descartes, recognized as the father of modern Western philosophy, were examined and defined as "interactional". Descartes suggested stimulus-response as the realm where the mind controls the body and the body may influence the rational mind out of the passion of our emotions. Transactionalists recognize Cartesian dualism as a form of disintegrating the transactional whole of man "into two complete substances, joined to another no one knows how." The body as a physical entity, on the one hand, and the soul or thought, on the other, was regarded in a Cartesian mindset as "an angel inhabiting a machine and directing it by means of the pineal gland" This tranactionalists reject. Ethics: reciprocal and co-constitutive While self-interest governs the ethical principles of Objectivism, here the principle is that man as an organism is in a reciprocal, constitutive relationship with her/his environment. Disabusing the psychological supposition of our "skin-boundedness" (discussed further below), transactionalism rejects the notion that we are apart from our environment or that man has dominion over it. Man, woman, and child must view life and be viewed in the undifferentiated whole of organism-environment. This reciprocal and co-constitutive relationship is what sets Transactionalism apart from other philosophies. What John Dewey meant by "reciprocal" was that:... consequences have to be determined on the grounds of what is selected and handled as means in exactly the same sense in which the converse holds and demands constant attention if activities are to be intelligently conducted.In order for a human being to know, in order for a human being to acquire intelligence, it must learn to relate to its Self as part of, not separate from the internal and/or external environments in which it lives as an organism-environment. Whether the environment is natural or human-made, whether discussing biology, sociology, culture, linguistics, history and memory, or economics and physics, every organism-environment is reciprocal, constitutive, socially-conditioned and constantly in flux demanding our ethical attention to conditions and consequences as we live life. John Dewey and Arthur Bentley, like Charles Sanders Peirce before them, were out to distinguish an ethical "living" logic rather than a static one. Both rejected the supposition that man had dominion over or governed behavior in his/her environment embracing a presupposition of transactionalism; we are reciprocal, co-constitutive, socially-conditioned, and motivated "together-at-once" as we seek solutions to living a good life. Transactionalists reject the "localization" of our psychology as if "skin-bound." Bentley wrote, "No creature lives merely under its skin." In other words, we should not define and distinguish experience in and from the subjective mind and feelings. Conversely, we cannot rely solely on external circumstances or some static or inherited logic. Galileo said of followers of Aristotle in seeking ethical knowledge that one should "come with arguments and demonstrations of your own...but bring us no more texts and naked authorities, for our disputes are about the sensible world and not a paper one." Humans are always transacting, "together-at-once," part of, shaped by, and shap-ing the experience we call "knowledge" as an organism-environment. Dewey and Bentley were intrigued by, and ultimately questioned, "the significance of the concept 'skin' and its role in philosophical and psychological thought." They offered a biological or natural justification that came to define a transactionalist approach. The known and what is known are both a function of man having "evolved among other organisms" within natural selection or evolution. Man's most intellectual and advanced "knowings" are not merely outgrowths of his own doing or being. The natural evolution of things outside our knowingness creates the very context in which our known and knowings arise. We are not inventing what is known outside or, in a vacuum beyond, who we are and who we are is an organism-environment together-at-once. We are not creatures separated by skin with an internal world of the mind and body "in here" separate from an environment of objects and people "out there". Human beings intelligently live, adapt to, and organize life in a reciprocal, co-constitutive experience that is what Dewey and Bentley term "trans-dermal". A "trans-dermal" experience demands knowledgeable and accurate inquiry into the conditions and consequences of each transaction where the organizing of ideas and acts (knowledge), is itself a transaction which grows out of the problem-solving and creative exploring within the universe of social situations in which we exist. Dewey and Bentley wrote, "truth, or for that matter falsity, is a function of the deliberately striven for consequences arising out of inquiry." Our behavior and acts in knowing, or transacting, must be considered "together" and "at-once" with its conditions and consequences for any ambitious movement or fulfillment to occur alone and among other people in any setting with objects and constructed inherited from others known and unknown over time. Transacting demands study, a slowing down of our movement, and the development of a transactional competence in order to fulfill certain needs or solve problems while functioning among others. In Dewey's final days, wrote Phillips, he emphasized the twin aspects of attending to both the means and the ends of any transaction: "It is…impossible to have an end-in-view or to anticipate the consequences of any proposed line of action." A "trans-dermal" consciousness is, therefore, key to moving ethically. To move, experience life, or transact in a principled manner, considering the reciprocal and co-constituitive nature of organism-environment becomes an object lesson governing both social behavior as well as in transacting from a trans-dermal view with objects or other bodies. Trans-dermal experience The work of Australian educational philosopher Vicki L. Lee further elucidates and breaks down what is "trans-dermal" experience—how it works and why it matters—based on her work in the philosophy of cognitive science, educational philosophy, and radical behaviorism about which she has published extensively. This complex paradigm is clearly evidenced by Lee in this thickly described example:Acts are more than movements. ...Our discriminations depend on movements and their contexts seen together-at-once or as an undifferentiated whole. In discriminating watering the garden from hosing the driveway, we see the bodily movements and their occasion and results. We see the garden, the watering implement, and so forth, as much as we see the body's activities. The notion of together-at-once emphasizes that we do not see movements and contexts separately and then infer the action. Rather the context is internal to the action, because without the context, the action would not be the action it is.A basic presupposition of the philosophy of transactionalism is to always consider that that which is known about the world (extra-dermal) is "directly concerned with the activity of the knower" which is merely from some sense of "skin-boundedness" (intra-dermal). The known and the knower, as Dewey and Bentley examined in detail in their collaborative publication, must always be considered "'twin aspects of common fact." Behavior, movement, and acts are not merely a function of the mind, of wishful or positive thinking or belief in external forces, nor can it be determined ethically from the philosophers of the past or knowledge written in a book. It is our ability to transact trans-dermally—to be and become ecologically-fit as an organism-environment—that begets truthful inquiry into living a good and satisfying life, functioning well among others. Philosophy and Women's Studies Professor Shannon Sullivan explores and applies "transactional knowing through embodied and relational lived experience" as a feminist epistemology developed out of the pragmatist tradition. Politics: cooperation and knowing-as-inquiry The branch of philosophy recognized as "politics" concerns the governance of community and group interaction, not merely the governing over a state or group as conventionally conceived in thoughts about local or national government. Transactionalists view politics as a cooperative, genuine interaction between all participating parties whether buyer-seller, student-teacher, or worker-boss; we are biological as well as social subjects involved not merely in "transacting" for our own advantage or gain but connected to other entities. "[S]ocial phenomena cannot be understood except as there is prior understanding of physical conditions and the laws of their [socio-biological] interactions," wrote John Dewey in Logic: The Theory of Inquiry. Furthermore, he added, "inquiry into [social phenomena], with respect both to data that are significant and to their relations or proper ordering, is conditioned upon extensive prior knowledge of physical phenomena and their laws. This fact accounts in part for the retarded and immature state of social subjects." Thus, cooperation and knowing as inquiry is foundational to governing communal affairs of any kind including economic trade and our educative process. In Laws of Motion (1920), physicist James Clerk Maxwell articulated the modern conception of "transaction" (or trans-action) used here. His conception is not exclusive to an economic context or limited to the opposition of a buyer-seller in trade or some analogous situation. Unlike commercial affairs, there is a radical departure from any tendency to perceive buyer-seller (in an organism-environment paradigm) as if they are opposing or separate forces. Transactionalists like Maxwell view the buyer and seller as "two parts [or aspects] of the same phenomenon." Dewey and Bentley apply this 'transactional' view to the domain of learning more than any other context. Referred to as the educative process, acting without knowing (described below) often sets up the separation or fracturing of the enjoined phenomenon (e.g., knowing is doing, organizing the mental or physical acts in a pragmatic way). Without knowing-as-inquiry, blindly acting as an organism in an environment often does not work with the exception of beginner's luck. Acting to understand knowing elicits pragmatic knowledge of functioning as an organism-environment; both knowing and acting must essentially involve inquiry into things that have happened and are happening in order to challenge assumptions and expectations which may be wrong in some context: Knowledge – if the term is to be employed at all – is a name for the product of competent inquiries, and is constituted only as the outcome of a particular inquiry.From the constitutive process of knowing and doing, knowledge is more than "a process taking place" or some "status" located in an organism's [of person's] mind. Knowledge arises from inquiry. It arises out of a kind of testing, an iterative process of inquiry into what we know and expect, that ensures a suitable fitness not only in solving problems (finding a solution). It ensures the fitness of the organism-environment, which may vary depending on the situation, the time and place, or the culture. While a person is central (or "nuclear" as in a nucleus) to a conception of organism-environment, human beings as organisms must abdicate any sense of dominion over their social-biological cosmos. Being human is but a part, and never outside, that cosmos or environment which they need to survive and they need to adapt to, to thrive. Each situation and assumptions about it—and this transactionalists assert is radical way of thinking—must be tested, examined, and determined by a series of iterative moves and activity based on the capacity of that organism's ability to fulfill its desired intentions to eventually thrive (or not). Dewey and Bentley later insisted that knowing "as inquiry, [is therefore] a way, or distinct form, of behavior," out of which a transactional competence is achieved. In our existing models of formal education, we bifurcate what Dewey viewed as indispensable. We, as a rule, segregate "utility and culture, absorption and expression, theory and practice....in any educational scheme" In 1952, progressive educator Elsie Ripley Clapp distinguished a similar commitment to a "cooperative transaction of inquiry" in a vision of education that enjoined those in a community and those inside a school. Intelligence—that which is acquired through knowledgeable inquiry and mental testing—allows man to analyze and foresee consequences derived from the past experiences shaping our biases and expectations. Without intelligence of this kind, one is unlikely to control his/her actions without preconceived dogma, rites, or beliefs that might be wrong without a proper inquiry. If the philosophical study of politics were actually considered a "study of force," transactionalists would assert that knowing "what actions are permissible" (or not) given the condition of being an organism-environment, then co-operation and knowing-as-inquiry into one's bodily condition and conditioning and the situation one is transacting in that conditions one's body, all this is vital to functioning successfully among others in any social situation or environment. In the Stanford Encyclopedia of Philosophy, it is noted that John Dewey was critical of the classical neoliberal stance that abstracts the individual from environment as if the individual precedes or lords from outside of a conception of society or social institutions. Dewey maintained that social institutions were not a "means for obtaining something for individuals. They are means for 'creating' individuals in a co-operative inquiry into knowing how to live a satisfying life (Reconstruction in Philosophy, MW12, 190–192)." [C]lassical liberalism treats the individual as 'something given.' Instead, Dewey argues, 'liberalism knows that an individual is nothing fixed, given ready-made. It is something achieved, and achieved not in isolation but with the aid and support of conditions, cultural and physical: — including in "cultural", economic, legal and political institutions as well as science and art' ('The Future of Liberalism', LW11: 291).For Dewey, such treatment is 'the most pervasive fallacy of philosophical thinking' ('Context and Thought', LW5, 5). Transactionalism is a radical form of governing one's self in one's environment(s). Transactionalism resists a political tendency to "divide up experienced phenomena, and to take the distinct analysed elements to be separate existences, independent both of the analysis and of each other." Intelligent thinking is anti-dualistic, accurate, forethought. It takes into account other people, communities, and cultures. It stems from a "deliberate control of what is done with reference to making what happens to us and what we do to things as fertile as possible of suggestions (of suggested meanings)." [emphasis added] Furthermore, intelligent thinking is a means for trying out the validity of those suggestions and other assumptions. The political governing of thinking towards dualisms and bifurcation as well as the "false conception of the individual" (apart from their environment) is what Dewey argued actually limits man's free (meaning "liberal") thought and action. All of this served as the core reasoning behind Dewey's development of an experimental philosophy that offset elite distortions of public education and learning. Individual as co-constitutive, organism-environment Transactionalist psychologists and educational philosophers reject the ideologies precipitated from Western ideologies of do-it-yourself or the phrase If it is to be, it's up to me! Such mentalities tend to lead to entitlement. The naiveté of slogans like "follow your passion" often deny any consideration of our trans-dermal condition—our internal fitness and the external fitness of who we are as organism-environment. Transactionalists assert that the "advancing conformity and coercive competition so characteristic of our times" demands reassessment. A new "philosophical-psychological complex" is offered that confronts the "ever increasing growth of bureaucratic rule and the attendant rise of a complacent citizenry." Given the intensification of globalization and migration, a trans-dermal consciousness allows for a transactional emphasis on "human dignity and uniqueness" despite "a matrix of anxiety and despair [and] feelings of alienation." Transactionalist psychologists and philosophers replace a once sought-after existentialism as a remedy to feelings of alienation with a trans-dermal, organism-environment orientation to living. Rather than applying a theory or approach that emphasizes the individual as a "free and responsible agent determining their own development through acts of the will," subjects are invited to co-create functioning among all other organism-environments, including the specific conditions and consequences of any objects and personalities involved, in order to intelligently structure existence in and among it all. The very act of participating in co-creation, according to transactionalists, gives and allows each person her/his unique status and dignity in their environment. Aesthetics: value-satisfaction from an assumptive world Distinct from an aesthetic theory of taste or a rationale for the beauty in an object of art, a transactionalist theory of aesthetics concerns the perceptual judgments we use to define value, purposeful activity or satisfaction in any experience. Based on studies by transactionalist psychologists Adelbert Ames, Jr. (known for The Ames Demonstrations), William Howard Ittelson, Hadley Cantril, along with John Dewey, the biological role of perception is key to understanding transactionalism. Perceiving is viewed as "part of the process of living by which each one of us, from his own particular point of view, creates for himself the world within which he has his life's experiences and through which he strives to gain his satisfactions." The sum total of these assumptions was recognized as the "assumptive world." The assumptive world stems from all that we experience, all the things and events we assess and assign meaning to, which function as a contextual whole also known as a transactional whole. Dewey also referred to the assumptive world as a "situation" (where organism and environment are inseparable) or as a "field" in which behavior, stimulus, and response are framed as if a reflexive circuit. Trevor Phillips noted, "To the modern transactionalist, experiences alter perceptual processes, and in the act of altering them, the purposing aspect of perception is either furthered or its fulfillment interfered with." It is through action, through movement, that man is capable of bringing forth a value-satisfaction—the perception of satisfying an aim or outcome—to her or his experience. Man's capacity to "sense value in the quality of his experience" was registered through his serial expectations and standards stemming from previous transactions throughout life. A theory of value is therefore derived from one's behavioral inquiry within an assumptive world. "Knowledge is a transaction that develops out of man's explorations within [that] cosmos." Transactionalists reject the notion that any truth is inherently settled or beyond question. The consequences of any inquiry will be dependent on the situation or transactional whole in which man as an organism-environment finds him- or her-self. Since our body and the physical environments and social ecologies in which it trans-acts are continually in flux across time and space, a singular or repetitive assumption carried over in an unthinking manner may not be valuable or satisfactory. To clarify the theory of valuation, John Dewey wrote: To declare something satisfactory [vs. satisfying] is to assert that it meets specifiable conditions. It is, in effect, a judgment that the thing 'will do'. It involves a prediction; it contemplates a future in which the thing will continue to serve; it will do. It asserts a consequence the thing will actively institute, it will do." Ultimately, transactionalism is a move away from the conclusion that knowledge depends on an independent knower and something to be known. The reality of a particular situation depends, transactionally speaking, on the interpretation place[d] upon the situation by a particular person. Interpretation is possible only through the accumulation of experience which, in effect, is what is meant by "assumptive world". Without the hitches and mistakes one encounters in the welter of daily living, the nature of the assumptive world would never arise into consciousness. The assumptive world, initially highlighted in the 25 experiments in perception known as "The Ames demonstrations," becomes the seeming reality of our world. Man's transactions of living involve, in sum, capacities and aspects of his nature operating together. To transact is to participate in the process of translating the ongoing energies of the environment into one's own perceptual awareness, and to transform the environment through the perceptual act. Value-satisfaction arises when the inadequacies of man's assumptive world are revealed or invalidated. Thereby, the consequences of any transactional experience determines what is valuable or what will do vs. that which is satisfying but will not do. The good life, for the transactionalist, consists of a unity of values, achieved by means of reflective thought, and accepted in the full light of their conditions and consequences. To transact is to act intelligently with an aim in mind while avoiding the tendency to surrender one's awareness to complacency or indifference that stems from mere information or untested knowledge. Without action, a person can fool herself, distort her sense of satisfaction or value on behalf of consequences she or others prefer. Through action, the individual perceptions as well as the shared perceptual common sense of an assumptive world are validated and modified. We predict and refine our conditions of life yet "any standard set for these value qualities is influenced by the individual's personal biological and life history." Transactionalism is a creative process that takes into account the unique biology and biography of persons involved. Generational significance The importance of the study of transactionalism arose in the late 1960s in response to an "alienation syndrome" among youth of that generation. As the counter-culture challenged and reassessed society's "philosophical-psychological complex, its Weltanschauung," their political and social alienation sparked protests against the war and the draft as well as historic racial rebellions in various U.S. cities. The Long hot summer of 1967 and the counterculture movement named the Summer of Love also in 1967 reflected the antipathy of young people who questioned everything. American society's norms and values were perceived as denying dignity to all. Riots of the period were studied in a report by the U.S. Kerner Commission and scholars began to study the patterns of alienation expressed by youth in the sixties. Youth sought a kind of existentialism expressed by a need to be "true to oneself." This current of alienation unfortunately veered away from a relevant understanding of the transactional whole taking into account the reciprocal and co-constitutive nature of man as an organism-environment fulfilling important conditions of life with others all the time. It resembles the famous line from Devotions upon Emergent Occasions, written by English poet John Donne – "No man is an island". Transactionalism presented an alternative to the limitation and unintended outcomes of the alienation syndrome. Benefits and applications Designed to account for all aspects of experience—subjective and objective—transactionalism requires a slowing down in assessing all the facts involved with the how, what, when, where, and why as we move to transact with others. It demands and requires always considering how a transaction with another and one's self (e.g., a parent or spouse spending additional hours socializing at the gym) is or is not beneficial to all involved in a transaction (e.g., other members of the family). The costs may be in time, attention, or money or in a condition of life (e.g., family, career, sleep). Transactionalism requires an interdependence of thought, study, and action. A transactionalist must account for one's biology and cognition (metaphysics); the ways knowing reality (epistemology); the reciprocal, co-constitutive, relationship (or ethics) between our social self and the interactions constrained by both our natural and human-made environment. We as human beings live in distinct sociological patterns with people, material and immaterial culture shaped by specific and ever-changing times and places further articulated by increasing migration and globalization. Transactionalism insists that one attend to the political distribution of goods and services along with the ways its value has and is exchanged and changing among people and groups (politics) as well as how persons are socialized to understand what it means to live a good life as well as fulfill those conditions over time (aesthetics). Transactionalism offers more than existentialism offered with its aim of being "true to oneself." The alienation that results from its orientation to the self at the expense of societal norms and values, even in small groups, often leads to naiveté, despair, frustration, agitation, and even indifference, at the expense of consciously organizing one's acts, while functioning among others, to fulfill one's unique and necessary interests in living a good and satisfying life. Transactionalism counters the naive "do as I see fit" mentality of authenticity regardless of other's needs and concerns, which inevitably leads to negative consequences and outcomes over time. Transactionalism depends upon the "integration of man and his surroundings." Phillips' dissertation documented the evolution of a "transactional approach;" one that rests on the fact that we are biological, linguistic, and that we must transact considering a trans-dermal experience of our thoughts, behavior, and exchange on every level imagined while ethically functioning with others well. A series of podcasts exemplify the application of a transactional approach to a diverse array of professionals from various countries.

Methodology

In its most common sense, methodology is the study of research methods. However, the term can also refer to the methods themselves or to the philosophical discussion of associated background assumptions. A method is a structured procedure for bringing about a certain goal, like acquiring knowledge or verifying knowledge claims. This normally involves various steps, like choosing a sample, collecting data from this sample, and interpreting the data. The study of methods concerns a detailed description and analysis of these processes. It includes evaluative aspects by comparing different methods. This way, it is assessed what advantages and disadvantages they have and for what research goals they may be used. These descriptions and evaluations depend on philosophical background assumptions. Examples are how to conceptualize the studied phenomena and what constitutes evidence for or against them. When understood in the widest sense, methodology also includes the discussion of these more abstract issues. Methodologies are traditionally divided into quantitative and qualitative research. Quantitative research is the main methodology of the natural sciences. It uses precise numerical measurements. Its goal is usually to find universal laws used to make predictions about future events. The dominant methodology in the natural sciences is called the scientific method. It includes steps like observation and the formulation of a hypothesis. Further steps are to test the hypothesis using an experiment, to compare the measurements to the expected results, and to publish the findings. Qualitative research is more characteristic of the social sciences and gives less prominence to exact numerical measurements. It aims more at an in-depth understanding of the meaning of the studied phenomena and less at universal and predictive laws. Common methods found in the social sciences are surveys, interviews, focus groups, and the nominal group technique. They differ from each other concerning their sample size, the types of questions asked, and the general setting. In recent decades, many social scientists have started using mixed-methods research, which combines quantitative and qualitative methodologies. Many discussions in methodology concern the question of whether the quantitative approach is superior, especially whether it is adequate when applied to the social domain. A few theorists reject methodology as a discipline in general. For example, some argue that it is useless since methods should be used rather than studied. Others hold that it is harmful because it restricts the freedom and creativity of researchers. Methodologists often respond to these objections by claiming that a good methodology helps researchers arrive at reliable theories in an efficient way. The choice of method often matters since the same factual material can lead to different conclusions depending on one's method. Interest in methodology has risen in the 20th century due to the increased importance of interdisciplinary work and the obstacles hindering efficient cooperation. Definitions The term "methodology" is associated with a variety of meanings. In its most common usage, it refers either to a method, to the field of inquiry studying methods, or to philosophical discussions of background assumptions involved in these processes. Some researchers distinguish methods from methodologies by holding that methods are modes of data collection while methodologies are more general research strategies that determine how to conduct a research project. In this sense, methodologies include various theoretical commitments about the intended outcomes of the investigation. As method The term "methodology" is sometimes used as a synonym for the term "method". A method is a way of reaching some predefined goal. It is a planned and structured procedure for solving a theoretical or practical problem. In this regard, methods stand in contrast to free and unstructured approaches to problem-solving. For example, descriptive statistics is a method of data analysis, radiocarbon dating is a method of determining the age of organic objects, sautéing is a method of cooking, and project-based learning is an educational method. The term "technique" is often used as a synonym both in the academic and the everyday discourse. Methods usually involve a clearly defined series of decisions and actions to be used under certain circumstances, usually expressable as a sequence of repeatable instructions. The goal of following the steps of a method is to bring about the result promised by it. In the context of inquiry, methods may be defined as systems of rules and procedures to discover regularities of nature, society, and thought. In this sense, methodology can refer to procedures used to arrive at new knowledge or to techniques of verifying and falsifying pre-existing knowledge claims. This encompasses various issues pertaining both to the collection of data and their analysis. Concerning the collection, it involves the problem of sampling and of how to go about the data collection itself, like surveys, interviews, or observation. There are also numerous methods of how the collected data can be analyzed using statistics or other ways of interpreting it to extract interesting conclusions. As study of methods However, many theorists emphasize the differences between the terms "method" and "methodology". In this regard, methodology may be defined as "the study or description of methods" or as "the analysis of the principles of methods, rules, and postulates employed by a discipline". This study or analysis involves uncovering assumptions and practices associated with the different methods and a detailed description of research designs and hypothesis testing. It also includes evaluative aspects: forms of data collection, measurement strategies, and ways to analyze data are compared and their advantages and disadvantages relative to different research goals and situations are assessed. In this regard, methodology provides the skills, knowledge, and practical guidance needed to conduct scientific research in an efficient manner. It acts as a guideline for various decisions researchers need to take in the scientific process. Methodology can be understood as the middle ground between concrete particular methods and the abstract and general issues discussed by the philosophy of science. In this regard, methodology comes after formulating a research question and helps the researchers decide what methods to use in the process. For example, methodology should assist the researcher in deciding why one method of sampling is preferable to another in a particular case or which form of data analysis is likely to bring the best results. Methodology achieves this by explaining, evaluating and justifying methods. Just as there are different methods, there are also different methodologies. Different methodologies provide different approaches to how methods are evaluated and explained and may thus make different suggestions on what method to use in a particular case. According to Aleksandr Georgievich Spirkin, "[a] methodology is a system of principles and general ways of organising and structuring theoretical and practical activity, and also the theory of this system". Helen Kara defines methodology as "a contextual framework for research, a coherent and logical scheme based on views, beliefs, and values, that guides the choices researchers make". Ginny E. Garcia and Dudley L. Poston understand methodology either as a complex body of rules and postulates guiding research or as the analysis of such rules and procedures. As a body of rules and postulates, a methodology defines the subject of analysis as well as the conceptual tools used by the analysis and the limits of the analysis. Research projects are usually governed by a structured procedure known as the research process. The goal of this process is given by a research question, which determines what kind of information one intends to acquire. As discussion of background assumptions Some theorists prefer an even wider understanding of methodology that involves not just the description, comparison, and evaluation of methods but includes additionally more general philosophical issues. One reason for this wider approach is that discussions of when to use which method often take various background assumptions for granted, for example, concerning the goal and nature of research. These assumptions can at times play an important role concerning which method to choose and how to follow it. For example, Thomas Kuhn argues in his The Structure of Scientific Revolutions that sciences operate within a framework or a paradigm that determines which questions are asked and what counts as good science. This concerns philosophical disagreements both about how to conceptualize the phenomena studied, what constitutes evidence for and against them, and what the general goal of researching them is. So in this wider sense, methodology overlaps with philosophy by making these assumptions explicit and presenting arguments for and against them. According to C. S. Herrman, a good methodology clarifies the structure of the data to be analyzed and helps the researchers see the phenomena in a new light. In this regard, a methodology is similar to a paradigm. A similar view is defended by Spirkin, who holds that a central aspect of every methodology is the world view that comes with it. The discussion of background assumptions can include metaphysical and ontological issues in cases where they have important implications for the proper research methodology. For example, a realist perspective considering the observed phenomena as an external and independent reality is often associated with an emphasis on empirical data collection and a more distanced and objective attitude. Idealists, on the other hand, hold that external reality is not fully independent of the mind and tend, therefore, to include more subjective tendencies in the research process as well. For the quantitative approach, philosophical debates in methodology include the distinction between the inductive and the hypothetico-deductive interpretation of the scientific method. For qualitative research, many basic assumptions are tied to philosophical positions such as hermeneutics, pragmatism, Marxism, critical theory, and postmodernism. According to Kuhn, an important factor in such debates is that the different paradigms are incommensurable. This means that there is no overarching framework to assess the conflicting theoretical and methodological assumptions. This critique puts into question various presumptions of the quantitative approach associated with scientific progress based on the steady accumulation of data. Other discussions of abstract theoretical issues in the philosophy of science are also sometimes included. This can involve questions like how and whether scientific research differs from fictional writing as well as whether research studies objective facts rather than constructing the phenomena it claims to study. In the latter sense, some methodologists have even claimed that the goal of science is less to represent a pre-existing reality and more to bring about some kind of social change in favor of repressed groups in society. Related terms and issues Viknesh Andiappan and Yoke Kin Wan use the field of process systems engineering to distinguish the term "methodology" from the closely related terms "approach", "method", "procedure", and "technique". On their view, "approach" is the most general term. It can be defined as "a way or direction used to address a problem based on a set of assumptions". An example is the difference between hierarchical approaches, which consider one task at a time in a hierarchical manner, and concurrent approaches, which consider them all simultaneously. Methodologies are a little more specific. They are general strategies needed to realize an approach and may be understood as guidelines for how to make choices. Often the term "framework" is used as a synonym. A method is a still more specific way of practically implementing the approach. Methodologies provide the guidelines that help researchers decide which method to follow. The method itself may be understood as a sequence of techniques. A technique is a step taken that can be observed and measured. Each technique has some immediate result. The whole sequence of steps is termed a "procedure". A similar but less complex characterization is sometimes found in the field of language teaching, where the teaching process may be described through a three-level conceptualization based on "approach", "method", and "technique". One question concerning the definition of methodology is whether it should be understood as a descriptive or a normative discipline. The key difference in this regard is whether methodology just provides a value-neutral description of methods or what scientists actually do. Many methodologists practice their craft in a normative sense, meaning that they express clear opinions about the advantages and disadvantages of different methods. In this regard, methodology is not just about what researchers actually do but about what they ought to do or how to perform good research. Types Theorists often distinguish various general types or approaches to methodology. The most influential classification contrasts quantitative and qualitative methodology. Quantitative and qualitative Quantitative research is closely associated with the natural sciences. It is based on precise numerical measurements, which are then used to arrive at exact general laws. This precision is also reflected in the goal of making predictions that can later be verified by other researchers. Examples of quantitative research include physicists at the Large Hadron Collider measuring the mass of newly created particles and positive psychologists conducting an online survey to determine the correlation between income and self-assessed well-being. Qualitative research is characterized in various ways in the academic literature but there are very few precise definitions of the term. It is often used in contrast to quantitative research for forms of study that do not quantify their subject matter numerically. However, the distinction between these two types is not always obvious and various theorists have argued that it should be understood as a continuum and not as a dichotomy. A lot of qualitative research is concerned with some form of human experience or behavior, in which case it tends to focus on a few individuals and their in-depth understanding of the meaning of the studied phenomena. Examples of the qualitative method are a market researcher conducting a focus group in order to learn how people react to a new product or a medical researcher performing an unstructured in-depth interview with a participant from a new experimental therapy to assess its potential benefits and drawbacks. It is also used to improve quantitative research, such as informing data collection materials and questionnaire design. Qualitative research is frequently employed in fields where the pre-existing knowledge is inadequate. This way, it is possible to get a first impression of the field and potential theories, thus paving the way for investigating the issue in further studies. Quantitative methods dominate in the natural sciences but both methodologies are used in the social sciences. Some social scientists focus mostly on one method while others try to investigate the same phenomenon using a variety of different methods. It is central to both approaches how the group of individuals used for the data collection is selected. This process is known as sampling. It involves the selection of a subset of individuals or phenomena to be measured. Important in this regard is that the selected samples are representative of the whole population, i.e. that no significant biases were involved when choosing. If this is not the case, the data collected does not reflect what the population as a whole is like. This affects generalizations and predictions drawn from the biased data. The number of individuals selected is called the sample size. For qualitative research, the sample size is usually rather small, while quantitative research tends to focus on big groups and collecting a lot of data. After the collection, the data needs to be analyzed and interpreted to arrive at interesting conclusions that pertain directly to the research question. This way, the wealth of information obtained is summarized and thus made more accessible to others. Especially in the case of quantitative research, this often involves the application of some form of statistics to make sense of the numerous individual measurements. Many discussions in the history of methodology center around the quantitative methods used by the natural sciences. A central question in this regard is to what extent they can be applied to other fields, like the social sciences and history. The success of the natural sciences was often seen as an indication of the superiority of the quantitative methodology and used as an argument to apply this approach to other fields as well. However, this outlook has been put into question in the more recent methodological discourse. In this regard, it is often argued that the paradigm of the natural sciences is a one-sided development of reason, which is not equally well suited to all areas of inquiry. The divide between quantitative and qualitative methods in the social sciences is one consequence of this criticism. Which method is more appropriate often depends on the goal of the research. For example, quantitative methods usually excel for evaluating preconceived hypotheses that can be clearly formulated and measured. Qualitative methods, on the other hand, can be used to study complex individual issues, often with the goal of formulating new hypotheses. This is especially relevant when the existing knowledge of the subject is inadequate. Important advantages of quantitative methods include precision and reliability. However, they have often difficulties in studying very complex phenomena that are commonly of interest to the social sciences. Additional problems can arise when the data is misinterpreted to defend conclusions that are not directly supported by the measurements themselves. In recent decades, many researchers in the social sciences have started combining both methodologies. This is known as mixed-methods research. A central motivation for this is that the two approaches can complement each other in various ways: some issues are ignored or too difficult to study with one methodology and are better approached with the other. In other cases, both approaches are applied to the same issue to produce more comprehensive and well-rounded results. Qualitative and quantitative research are often associated with different research paradigms and background assumptions. Qualitative researchers often use an interpretive or critical approach while quantitative researchers tend to prefer a positivistic approach. Important disagreements between these approaches concern the role of objectivity and hard empirical data as well as the research goal of predictive success rather than in-depth understanding or social change. Others Various other classifications have been proposed. One distinguishes between substantive and formal methodologies. Substantive methodologies tend to focus on one specific area of inquiry. The findings are initially restricted to this specific field but may be transferrable to other areas of inquiry. Formal methodologies, on the other hand, are based on a variety of studies and try to arrive at more general principles applying to different fields. They may also give particular prominence to the analysis of the language of science and the formal structure of scientific explanation. A closely related classification distinguishes between philosophical, general scientific, and special scientific methods. One type of methodological outlook is called "proceduralism". According to it, the goal of methodology is to boil down the research process to a simple set of rules or a recipe that automatically leads to good research if followed precisely. However, it has been argued that, while this ideal may be acceptable for some forms of quantitative research, it fails for qualitative research. One argument for this position is based on the claim that research is not a technique but a craft that cannot be achieved by blindly following a method. In this regard, research depends on forms of creativity and improvisation to amount to good science. Other types include inductive, deductive, and transcendental methods. Inductive methods are common in the empirical sciences and proceed through inductive reasoning from many particular observations to arrive at general conclusions, often in the form of universal laws. Deductive methods, also referred to as axiomatic methods, are often found in formal sciences, such as geometry. They start from a set of self-evident axioms or first principles and use deduction to infer interesting conclusions from these axioms. Transcendental methods are common in Kantian and post-Kantian philosophy. They start with certain particular observations. It is then argued that the observed phenomena can only exist if their conditions of possibility are fulfilled. This way, the researcher may draw general psychological or metaphysical conclusions based on the claim that the phenomenon would not be observable otherwise. Importance It has been argued that a proper understanding of methodology is important for various issues in the field of research. They include both the problem of conducting efficient and reliable research as well as being able to validate knowledge claims by others. Method is often seen as one of the main factors of scientific progress. This is especially true for the natural sciences where the developments of experimental methods in the 16th and 17th century are often seen as the driving force behind the success and prominence of the natural sciences. In some cases, the choice of methodology may have a severe impact on a research project. The reason is that very different and sometimes even opposite conclusions may follow from the same factual material based on the chosen methodology. Aleksandr Georgievich Spirkin argues that methodology, when understood in a wide sense, is of great importance since the world presents us with innumerable entities and relations between them. Methods are needed to simplify this complexity and find a way of mastering it. On the theoretical side, this concerns ways of forming true beliefs and solving problems. On the practical side, this concerns skills of influencing nature and dealing with each other. These different methods are usually passed down from one generation to the next. Spirkin holds that the interest in methodology on a more abstract level arose in attempts to formalize these techniques to improve them as well as to make it easier to use them and pass them on. In the field of research, for example, the goal of this process is to find reliable means to acquire knowledge in contrast to mere opinions acquired by unreliable means. In this regard, "methodology is a way of obtaining and building up ... knowledge". Various theorists have observed that the interest in methodology has risen significantly in the 20th century. This increased interest is reflected not just in academic publications on the subject but also in the institutionalized establishment of training programs focusing specifically on methodology. This phenomenon can be interpreted in different ways. Some see it as a positive indication of the topic's theoretical and practical importance. Others interpret this interest in methodology as an excessive preoccupation that draws time and energy away from doing research on concrete subjects by applying the methods instead of researching them. This ambiguous attitude towards methodology is sometimes even exemplified in the same person. Max Weber, for example, criticized the focus on methodology during his time while making significant contributions to it himself. Spirkin believes that one important reason for this development is that contemporary society faces many global problems. These problems cannot be solved by a single researcher or a single discipline but are in need of collaborative efforts from many fields. Such interdisciplinary undertakings profit a lot from methodological advances, both concerning the ability to understand the methods of the respective fields and in relation to developing more homogeneous methods equally used by all of them. Criticism Most criticism of methodology is directed at one specific form or understanding of it. In such cases, one particular methodological theory is rejected but not methodology at large when understood as a field of research comprising many different theories. In this regard, many objections to methodology focus on the quantitative approach, specifically when it is treated as the only viable approach. Nonetheless, there are also more fundamental criticisms of methodology in general. They are often based on the idea that there is little value to abstract discussions of methods and the reasons cited for and against them. In this regard, it may be argued that what matters is the correct employment of methods and not their meticulous study. Sigmund Freud, for example, compared methodologists to "people who clean their glasses so thoroughly that they never have time to look through them". According to C. Wright Mills, the practice of methodology often degenerates into a "fetishism of method and technique". Some even hold that methodological reflection is not just a waste of time but actually has negative side effects. Such an argument may be defended by analogy to other skills that work best when the agent focuses only on employing them. In this regard, reflection may interfere with the process and lead to avoidable mistakes. According to an example by Gilbert Ryle, "[w]e run, as a rule, worse, not better, if we think a lot about our feet". A less severe version of this criticism does not reject methodology per se but denies its importance and rejects an intense focus on it. In this regard, methodology has still a limited and subordinate utility but becomes a diversion or even counterproductive by hindering practice when given too much emphasis. Another line of criticism concerns more the general and abstract nature of methodology. It states that the discussion of methods is only useful in concrete and particular cases but not concerning abstract guidelines governing many or all cases. Some anti-methodologists reject methodology based on the claim that researchers need freedom to do their work effectively. But this freedom may be constrained and stifled by "inflexible and inappropriate guidelines". For example, according to Kerry Chamberlain, a good interpretation needs creativity to be provocative and insightful, which is prohibited by a strictly codified approach. Chamberlain uses the neologism "methodolatry" to refer to this alleged overemphasis on methodology. Similar arguments are given in Paul Feyerabend's book "Against Method". However, these criticisms of methodology in general are not always accepted. Many methodologists defend their craft by pointing out how the efficiency and reliability of research can be improved through a proper understanding of methodology. A criticism of more specific forms of methodology is found in the works of the sociologist Howard S. Becker. He is quite critical of methodologists based on the claim that they usually act as advocates of one particular method usually associated with quantitative research. An often-cited quotation in this regard is that "[m]ethodology is too important to be left to methodologists". Alan Bryman has rejected this negative outlook on methodology. He holds that Becker's criticism can be avoided by understanding methodology as an inclusive inquiry into all kinds of methods and not as a mere doctrine for converting non-believers to one's preferred method. In different fields Part of the importance of methodology is reflected in the number of fields to which it is relevant. They include the natural sciences and the social sciences as well as philosophy and mathematics. Natural sciences The dominant methodology in the natural sciences (like astronomy, biology, chemistry, geoscience, and physics) is called the scientific method. Its main cognitive aim is usually seen as the creation of knowledge, but various closely related aims have also been proposed, like understanding, explanation, or predictive success. Strictly speaking, there is no one single scientific method. In this regard, the expression "scientific method" refers not to one specific procedure but to different general or abstract methodological aspects characteristic of all the aforementioned fields. Important features are that the problem is formulated in a clear manner and that the evidence presented for or against a theory is public, reliable, and replicable. The last point is important so that other researchers are able to repeat the experiments to confirm or disconfirm the initial study. For this reason, various factors and variables of the situation often have to be controlled to avoid distorting influences and to ensure that subsequent measurements by other researchers yield the same results. The scientific method is a quantitative approach that aims at obtaining numerical data. This data is often described using mathematical formulas. The goal is usually to arrive at some universal generalizations that apply not just to the artificial situation of the experiment but to the world at large. Some data can only be acquired using advanced measurement instruments. In cases where the data is very complex, it is often necessary to employ sophisticated statistical techniques to draw conclusions from it. The scientific method is often broken down into several steps. In a typical case, the procedure starts with regular observation and the collection of information. These findings then lead the scientist to formulate a hypothesis describing and explaining the observed phenomena. The next step consists in conducting an experiment designed for this specific hypothesis. The actual results of the experiment are then compared to the expected results based on one's hypothesis. The findings may then be interpreted and published, either as a confirmation or disconfirmation of the initial hypothesis. Two central aspects of the scientific method are observation and experimentation. This distinction is based on the idea that experimentation involves some form of manipulation or intervention. This way, the studied phenomena are actively created or shaped. For example, a biologist inserting viral DNA into a bacterium is engaged in a form of experimentation. Pure observation, on the other hand, involves studying independent entities in a passive manner. This is the case, for example, when astronomers observe the orbits of astronomical objects far away. Observation played the main role in ancient science. The scientific revolution in the 16th and 17th century affected a paradigm change that gave a much more central role to experimentation in the scientific methodology. This is sometimes expressed by stating that modern science actively "puts questions to nature". While the distinction is usually clear in the paradigmatic cases, there are also many intermediate cases where it is not obvious whether they should be characterized as observation or as experimentation. A central discussion in this field concerns the distinction between the inductive and the hypothetico-deductive methodology. The core disagreement between these two approaches concerns their understanding of the confirmation of scientific theories. The inductive approach holds that a theory is confirmed or supported by all its positive instances, i.e. by all the observations that exemplify it. For example, the observations of many white swans confirm the universal hypothesis that "all swans are white". The hypothetico-deductive approach, on the other hand, focuses not on positive instances but on deductive consequences of the theory. This way, the researcher uses deduction before conducting an experiment to infer what observations they expect. These expectations are then compared to the observations they actually make. This approach often takes a negative form based on falsification. In this regard, positive instances do not confirm a hypothesis but negative instances disconfirm it. Positive indications that the hypothesis is true are only given indirectly if many attempts to find counterexamples have failed. A cornerstone of this approach is the null hypothesis, which assumes that there is no connection (see causality) between whatever is being observed. It is up to the researcher to do all they can to disprove their own hypothesis through relevant methods or techniques, documented in a clear and replicable process. If they fail to do so, it can be concluded that the null hypothesis is false, which provides support for their own hypothesis about the relation between the observed phenomena. Social sciences Significantly more methodological variety is found in the social sciences, where both quantitative and qualitative approaches are used. They employ various forms of data collection, such as surveys, interviews, focus groups, and the nominal group technique. Surveys belong to quantitative research and usually involve some form of questionnaire given to a large group of individuals. It is paramount that the questions are easily understandable by the participants since the answers might not have much value otherwise. Surveys normally restrict themselves to closed questions in order to avoid various problems that come with the interpretation of answers to open questions. They contrast in this regard to interviews, which put more emphasis on the individual participant and often involve open questions. Structured interviews are planned in advance and have a fixed set of questions given to each individual. They contrast with unstructured interviews, which are closer to a free-flow conversation and require more improvisation on the side of the interviewer for finding interesting and relevant questions. Semi-structured interviews constitute a middle ground: they include both predetermined questions and questions not planned in advance. Structured interviews make it easier to compare the responses of the different participants and to draw general conclusions. However, they also limit what may be discovered and thus constrain the investigation in many ways. Depending on the type and depth of the interview, this method belongs either to quantitative or to qualitative research. The terms research conversation and muddy interview have been used to describe interviews conducted in informal settings which may not occur purely for the purposes of data collection. Some researcher employ the go-along method by conducting interviews while they and the participants navigate through and engage with their environment. Focus groups are a qualitative research method often used in market research. They constitute a form of group interview involving a small number of demographically similar people. Researchers can use this method to collect data based on the interactions and responses of the participants. The interview often starts by asking the participants about their opinions on the topic under investigation, which may, in turn, lead to a free exchange in which the group members express and discuss their personal views. An important advantage of focus groups is that they can provide insight into how ideas and understanding operate in a cultural context. However, it is usually difficult to use these insights to discern more general patterns true for a wider public. One advantage of focus groups is that they can help the researcher identify a wide range of distinct perspectives on the issue in a short time. The group interaction may also help clarify and expand interesting contributions. One disadvantage is due to the moderator's personality and group effects, which may influence the opinions stated by the participants. When applied to cross-cultural settings, cultural and linguistic adaptations and group composition considerations are important to encourage greater participation in the group discussion. The nominal group technique is similar to focus groups with a few important differences. The group often consists of experts in the field in question. The group size is similar but the interaction between the participants is more structured. The goal is to determine how much agreement there is among the experts on the different issues. The initial responses are often given in written form by each participant without a prior conversation between them. In this manner, group effects potentially influencing the expressed opinions are minimized. In later steps, the different responses and comments may be discussed and compared to each other by the group as a whole. Most of these forms of data collection involve some type of observation. Observation can take place either in a natural setting, i.e. the field, or in a controlled setting such as a laboratory. Controlled settings carry with them the risk of distorting the results due to their artificiality. Their advantage lies in precisely controlling the relevant factors, which can help make the observations more reliable and repeatable. Non-participatory observation involves a distanced or external approach. In this case, the researcher focuses on describing and recording the observed phenomena without causing or changing them, in contrast to participatory observation. An important methodological debate in the field of social sciences concerns the question of whether they deal with hard, objective, and value-neutral facts, as the natural sciences do. Positivists agree with this characterization, in contrast to interpretive and critical perspectives on the social sciences. According to William Neumann, positivism can be defined as "an organized method for combining deductive logic with precise empirical observations of individual behavior in order to discover and confirm a set of probabilistic causal laws that can be used to predict general patterns of human activity". This view is rejected by interpretivists. Max Weber, for example, argues that the method of the natural sciences is inadequate for the social sciences. Instead, more importance is placed on meaning and how people create and maintain their social worlds. The critical methodology in social science is associated with Karl Marx and Sigmund Freud. It is based on the assumption that many of the phenomena studied using the other approaches are mere distortions or surface illusions. It seeks to uncover deeper structures of the material world hidden behind these distortions. This approach is often guided by the goal of helping people effect social changes and improvements. Philosophy Philosophical methodology is the metaphilosophical field of inquiry studying the methods used in philosophy. These methods structure how philosophers conduct their research, acquire knowledge, and select between competing theories. It concerns both descriptive issues of what methods have been used by philosophers in the past and normative issues of which methods should be used. Many philosophers emphasize that these methods differ significantly from the methods found in the natural sciences in that they usually do not rely on experimental data obtained through measuring equipment. Which method one follows can have wide implications for how philosophical theories are constructed, what theses are defended, and what arguments are cited in favor or against. In this regard, many philosophical disagreements have their source in methodological disagreements. Historically, the discovery of new methods, like methodological skepticism and the phenomenological method, has had important impacts on the philosophical discourse. A great variety of methods has been employed throughout the history of philosophy. Methodological skepticism gives special importance to the role of systematic doubt. This way, philosophers try to discover absolutely certain first principles that are indubitable. The geometric method starts from such first principles and employs deductive reasoning to construct a comprehensive philosophical system based on them. Phenomenology gives particular importance to how things appear to be. It consists in suspending one's judgments about whether these things actually exist in the external world. This technique is known as epoché and can be used to study appearances independent of assumptions about their causes. The method of conceptual analysis came to particular prominence with the advent of analytic philosophy. It studies concepts by breaking them down into their most fundamental constituents to clarify their meaning. Common sense philosophy uses common and widely accepted beliefs as a philosophical tool. They are used to draw interesting conclusions. This is often employed in a negative sense to discredit radical philosophical positions that go against common sense. Ordinary language philosophy has a very similar method: it approaches philosophical questions by looking at how the corresponding terms are used in ordinary language. Many methods in philosophy rely on some form of intuition. They are used, for example, to evaluate thought experiments, which involve imagining situations to assess their possible consequences in order to confirm or refute philosophical theories. The method of reflective equilibrium tries to form a coherent perspective by examining and reevaluating all the relevant beliefs and intuitions. Pragmatists focus on the practical consequences of philosophical theories to assess whether they are true or false. Experimental philosophy is a recently developed approach that uses the methodology of social psychology and the cognitive sciences for gathering empirical evidence and justifying philosophical claims. Mathematics In the field of mathematics, various methods can be distinguished, such as synthetic, analytic, deductive, inductive, and heuristic methods. For example, the difference between synthetic and analytic methods is that the former start from the known and proceed to the unknown while the latter seek to find a path from the unknown to the known. Geometry textbooks often proceed using the synthetic method. They start by listing known definitions and axioms and proceed by taking inferential steps, one at a time, until the solution to the initial problem is found. An important advantage of the synthetic method is its clear and short logical exposition. One disadvantage is that it is usually not obvious in the beginning that the steps taken lead to the intended conclusion. This may then come as a surprise to the reader since it is not explained how the mathematician knew in the beginning which steps to take. The analytic method often reflects better how mathematicians actually make their discoveries. For this reason, it is often seen as the better method for teaching mathematics. It starts with the intended conclusion and tries to find another formula from which it can be deduced. It then goes on to apply the same process to this new formula until it has traced back all the way to already proven theorems. The difference between the two methods concerns primarily how mathematicians think and present their proofs. The two are equivalent in the sense that the same proof may be presented either way. Statistics Statistics investigates the analysis, interpretation, and presentation of data. It plays a central role in many forms of quantitative research that have to deal with the data of many observations and measurements. In such cases, data analysis is used to cleanse, transform, and model the data to arrive at practically useful conclusions. There are numerous methods of data analysis. They are usually divided into descriptive statistics and inferential statistics. Descriptive statistics restricts itself to the data at hand. It tries to summarize the most salient features and present them in insightful ways. This can happen, for example, by visualizing its distribution or by calculating indices such as the mean or the standard deviation. Inferential statistics, on the other hand, uses this data based on a sample to draw inferences about the population at large. That can take the form of making generalizations and predictions or by assessing the probability of a concrete hypothesis. Pedagogy Pedagogy can be defined as the study or science of teaching methods. In this regard, it is the methodology of education: it investigates the methods and practices that can be applied to fulfill the aims of education. These aims include the transmission of knowledge as well as fostering skills and character traits. Its main focus is on teaching methods in the context of regular schools. But in its widest sense, it encompasses all forms of education, both inside and outside schools. In this wide sense, pedagogy is concerned with "any conscious activity by one person designed to enhance learning in another". The teaching happening this way is a process taking place between two parties: teachers and learners. Pedagogy investigates how the teacher can help the learner undergo experiences that promote their understanding of the subject matter in question. Various influential pedagogical theories have been proposed. Mental-discipline theories were already common in ancient Greek and state that the main goal of teaching is to train intellectual capacities. They are usually based on a certain ideal of the capacities, attitudes, and values possessed by educated people. According to naturalistic theories, there is an inborn natural tendency in children to develop in a certain way. For them, pedagogy is about how to help this process happen by ensuring that the required external conditions are set up. Herbartianism identifies five essential components of teaching: preparation, presentation, association, generalization, and application. They correspond to different phases of the educational process: getting ready for it, showing new ideas, bringing these ideas in relation to known ideas, understanding the general principle behind their instances, and putting what one has learned into practice. Learning theories focus primarily on how learning takes place and formulate the proper methods of teaching based on these insights. One of them is apperception or association theory, which understands the mind primarily in terms of associations between ideas and experiences. On this view, the mind is initially a blank slate. Learning is a form of developing the mind by helping it establish the right associations. Behaviorism is a more externally oriented learning theory. It identifies learning with classical conditioning, in which the learner's behavior is shaped by presenting them with a stimulus with the goal of evoking and solidifying the desired response pattern to this stimulus. The choice of which specific method is best to use depends on various factors, such as the subject matter and the learner's age. Interest and curiosity on the side of the student are among the key factors of learning success. This means that one important aspect of the chosen teaching method is to ensure that these motivational forces are maintained, through intrinsic or extrinsic motivation. Many forms of education also include regular assessment of the learner's progress, for example, in the form of tests. This helps to ensure that the teaching process is successful and to make adjustments to the chosen method if necessary. Related concepts Methodology has several related concepts, such as paradigm and algorithm. In the context of science, a paradigm is a conceptual worldview. It consists of a number of basic concepts and general theories, that determine how the studied phenomena are to be conceptualized and which scientific methods are considered reliable for studying them. Various theorists emphasize similar aspects of methodologies, for example, that they shape the general outlook on the studied phenomena and help the researcher see them in a new light. In computer science, an algorithm is a procedure or methodology to reach the solution of a problem with a finite number of steps. Each step has to be precisely defined so it can be carried out in an unambiguous manner for each application. For example, the Euclidean algorithm is an algorithm that solves the problem of finding the greatest common divisor of two integers. It is based on simple steps like comparing the two numbers and subtracting one from the other.

Food

Food is any substance consumed by an organism for nutritional support. Food is usually of plant, animal, or fungal origin and contains essential nutrients such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth. Different species of animals have different feeding behaviours that satisfy the needs of their metabolisms and have evolved to fill a specific ecological niche within specific geographical contexts. Omnivorous humans are highly adaptable and have adapted to obtain food in many different ecosystems. Humans generally use cooking to prepare food for consumption. The majority of the food energy required is supplied by the industrial food industry, which produces food through intensive agriculture and distributes it through complex food processing and food distribution systems. This system of conventional agriculture relies heavily on fossil fuels, which means that the food and agricultural systems are one of the major contributors to climate change, accounting for as much as 37% of total greenhouse gas emissions. The food system has significant impacts on a wide range of other social and political issues, including sustainability, biological diversity, economics, population growth, water supply, and food security. Food safety and security are monitored by international agencies like the International Association for Food Protection, the World Resources Institute, the World Food Programme, the Food and Agriculture Organization, and the International Food Information Council. Definition and classification Food is any substance consumed to provide nutritional support and energy to an organism. It can be raw, processed, or formulated and is consumed orally by animals for growth, health, or pleasure. Food is mainly composed of water, lipids, proteins, and carbohydrates. Minerals (e.g., salts) and organic substances (e.g., vitamins) can also be found in food. Plants, algae, and some microorganisms use photosynthesis to make some of their own nutrients. Water is found in many foods and has been defined as a food by itself. Water and fiber have low energy densities, or calories, while fat is the most energy-dense component. Some inorganic (non-food) elements are also essential for plant and animal functioning. Human food can be classified in various ways, either by related content or by how it is processed. The number and composition of food groups can vary. Most systems include four basic groups that describe their origin and relative nutritional function: Vegetables and Fruit, Cereals and Bread, Dairy, and Meat. Studies that look into diet quality group food into whole grains/cereals, refined grains/cereals, vegetables, fruits, nuts, legumes, eggs, dairy products, fish, red meat, processed meat, and sugar-sweetened beverages. The Food and Agriculture Organization and World Health Organization use a system with nineteen food classifications: cereals, roots, pulses and nuts, milk, eggs, fish and shellfish, meat, insects, vegetables, fruits, fats and oils, sweets and sugars, spices and condiments, beverages, foods for nutritional uses, food additives, composite dishes and savoury snacks. Food sources In a given ecosystem, food forms a web of interlocking chains with primary producers at the bottom and apex predators at the top. Other aspects of the web include detrovores (that eat detritis) and decomposers (that break down dead organisms). Primary producers include algae, plants, bacteria and protists that acquire their energy from sunlight. Primary consumers are the herbivores that consume the plants, and secondary consumers are the carnivores that consume those herbivores. Some organisms, including most mammals and birds, diet consists of both animals and plants, and they are considered omnivores. The chain ends with the apex predators, the animals that have no known predators in its ecosystem. Humans are considered apex predators. Humans are omnivores, finding sustenance in vegetables, fruits, cooked meat, milk, eggs, mushrooms and seaweed. Cereal grain is a staple food that provides more food energy worldwide than any other type of crop. Corn (maize), wheat, and rice account for 87% of all grain production worldwide. Just over half of the world's crops are used to feed humans (55 percent), with 36 percent grown as animal feed and 9 percent for biofuels. Fungi and bacteria are also used in the preparation of fermented foods like bread, wine, cheese and yogurt. Photosynthesis During photosynthesis, energy from the sun is absorbed and used to transform water and carbon dioxide in the air or soil into oxygen and glucose. The oxygen is then released, and the glucose stored as an energy reserve. Photosynthetic plants, algae and certain bacteria often represent the lowest point of the food chains, making photosynthesis the primary source of energy and food for nearly all life on earth. Plants also absorb important nutrients and minerals from the air, natural waters, and soil. Carbon, oxygen and hydrogen are absorbed from the air or water and are the basic nutrients needed for plant survival. The three main nutrients absorbed from the soil for plant growth are nitrogen, phosphorus and potassium, with other important nutrients including calcium, sulfur, magnesium, iron boron, chlorine, manganese, zinc, copper molybdenum and nickel. Microorganisms Bacteria and other microorganisms also form the lower rungs of the food chain. They obtain their energy from photosynthesis or by breaking down dead organisms, waste or chemical compounds. Some form symbiotic relationships with other organisms to obtain their nutrients. Bacteria provide a source of food for protozoa, who in turn provide a source of food for other organisms such as small invertebrates. Other organisms that feed on bacteria include nematodes, fan worms, shellfish and a species of snail. In the marine environment, plankton (which includes bacteria, archaea, algae, protozoa and microscopic fungi) provide a crucial source of food to many small and large aquatic organisms. Without bacteria, life would scarcely exist because bacteria convert atmospheric nitrogen into nutritious ammonia. Ammonia is the precursor to proteins, nucleic acids, and most vitamins. Since the advent of industrial process for nitrogen fixation, the Haber-Bosch Process, the majority of ammonia in the world is human-made. Plants Plants as a food source are divided into seeds, fruits, vegetables, legumes, grains and nuts. Where plants fall within these categories can vary, with botanically described fruits such as the tomato, squash, pepper and eggplant or seeds like peas commonly considered vegetables. Food is a fruit if the part eaten is derived from the reproductive tissue, so seeds, nuts and grains are technically fruit. From a culinary perspective, fruits are generally considered the remains of botanically described fruits after grains, nuts, seeds and fruits used as vegetables are removed. Grains can be defined as seeds that humans eat or harvest, with cereal grains (oats, wheat, rice, corn, barley, rye, sorghum and millet) belonging to the Poaceae (grass) family and pulses coming from the Fabaceae (legume) family. Whole grains are foods that contain all the elements of the original seed (bran, germ, and endosperm). Nuts are dry fruits, distinguishable by their woody shell. Fleshy fruits (distinguishable from dry fruits like grain, seeds and nuts) can be further classified as stone fruits (cherries and peaches), pome fruits (apples, pears), berries (blackberry, strawberry), citrus (oranges, lemon), melons (watermelon, cantaloupe), Mediterranean fruits (grapes, fig), tropical fruits (banana, pineapple). Vegetables refer to any other part of the plant that can be eaten, including roots, stems, leaves, flowers, bark or the entire plant itself. These include root vegetables (potatoes and carrots), bulbs (onion family), flowers (cauliflower and broccoli), leaf vegetables (spinach and lettuce) and stem vegetables (celery and asparagus). The carbohydrate, protein and lipid content of plants is highly variable. Carbohydrates are mainly in the form of starch, fructose, glucose and other sugars. Most vitamins are found from plant sources, with exceptions of vitamin D and vitamin B12. Minerals can also be plentiful or not. Fruit can consist of up to 90% water, contain high levels of simple sugars that contribute to their sweet taste, and have a high vitamin C content. Compared to fleshy fruit (excepting Bananas) vegetables are high in starch, potassium, dietary fiber, folate and vitamins and low in fat and calories. Grains are more starch based and nuts have a high protein, fibre, vitamin E and B content. Seeds are a good source of food for animals because they are abundant and contain fibre and healthful fats, such as omega-3 fats. Complicated chemical interactions can enhance or depress bioavailability of certain nutrients. Phytates can prevent the release of some sugars and vitamins. Animals that only eat plants are called herbivores, with those that mostly just eat fruits known as frugivores, leaves, while shoot eaters are folivores (pandas) and wood eaters termed xylophages (termites). Frugivores include a diverse range of species from annelids to elephants, chimpanzees and many birds. About 182 fish consume seeds or fruit. Animals (domesticated and wild) use as many types of grasses that have adapted to different locations as their main source of nutrients. Humans eat thousands of plant species; there may be as many as 75,000 edible species of angiosperms, of which perhaps 7,000 are often eaten. Plants can be processed into breads, pasta, cereals, juices and jams or raw ingredients such as sugar, herbs, spices and oils can be extracted. Oilseeds are pressed to produce rich oils⁣sunflower, flaxseed, rapeseed (including canola oil) and sesame. Many plants and animals have coevolved in such a way that the fruit is a good source of nutrition to the animal who then excretes the seeds some distance away, allowing greater dispersal. Even seed predation can be mutually beneficial, as some seeds can survive the digestion process. Insects are major eaters of seeds, with ants being the only real seed dispersers. Birds, although being major dispersers, only rarely eat seeds as a source of food and can be identified by their thick beak that is used to crack open the seed coat. Mammals eat a more diverse range of seeds, as they are able to crush harder and larger seeds with their teeth. Animals Animals are used as food either directly or indirectly. This includes meat, eggs, shellfish and dairy products like milk and cheese. They are an important source of protein and are considered complete proteins for human consumption as they contain all the essential amino acids that the human body needs. One steak, chicken breast or pork chop contains about 30 grams of protein. One large egg has 7 grams of protein. A serving of cheese has about 15 grams of protein. And 1 cup of milk has about 8 grams of protein. Other nutrients found in animal products include calories, fat, essential vitamins (including B12) and minerals (including zinc, iron, calcium, magnesium). Food products produced by animals include milk produced by mammary glands, which in many cultures is drunk or processed into dairy products (cheese, butter, etc.). Eggs laid by birds and other animals are eaten and bees produce honey, a reduced nectar from flowers that is used as a popular sweetener in many cultures. Some cultures consume blood, such as in blood sausage, as a thickener for sauces, or in a cured, salted form for times of food scarcity, and others use blood in stews such as jugged hare. Taste Animals, specifically humans, typically have five different types of tastes: sweet, sour, salty, bitter, and umami. The differing tastes are important for distinguishing between foods that are nutritionally beneficial and those which may contain harmful toxins. As animals have evolved, the tastes that provide the most energy are the most pleasant to eat while others are not enjoyable, although humans in particular can acquire a preference for some substances which are initially unenjoyable. Water, while important for survival, has no taste. Sweetness is almost always caused by a type of simple sugar such as glucose or fructose, or disaccharides such as sucrose, a molecule combining glucose and fructose. Sourness is caused by acids, such as vinegar in alcoholic beverages. Sour foods include citrus, specifically lemons and limes. Sour is evolutionarily significant as it can signal a food that may have gone rancid due to bacteria. Saltiness is the taste of alkali metal ions such as sodium and potassium. It is found in almost every food in low to moderate proportions to enhance flavor. Bitter taste is a sensation considered unpleasant characterised by having a sharp, pungent taste. Unsweetened dark chocolate, caffeine, lemon rind, and some types of fruit are known to be bitter. Umami, commonly described as savory, is a marker of proteins and characteristic of broths and cooked meats. Foods that have a strong umami flavor include cheese, meat and mushrooms. While most animals taste buds are located in their mouth, some insects taste receptors are located on their legs and some fish have taste buds along their entire body. Dogs, cats and birds have relatively few taste buds (chickens have about 30), adult humans have between 2000 and 4000, while catfish can have more than a million. Herbivores generally have more than carnivores as they need to tell which plants may be poisonous. Not all mammals share the same tastes: some rodents can taste starch, cats cannot taste sweetness, and several carnivores (including hyenas, dolphins, and sea lions) have lost the ability to sense up to four of the five taste modalities found in humans. Digestion Food is broken into nutrient components through digestive process. Proper digestion consists of mechanical processes (chewing, peristalsis) and chemical processes (digestive enzymes and microorganisms). The digestive systems of herbivores and carnivores are very different as plant matter is harder to digest. Carnivores mouths are designed for tearing and biting compared to the grinding action found in herbivores. Herbivores however have comparatively longer digestive tracts and larger stomachs to aid in digesting the cellulose in plants. Food safety According to the World Health Organization (WHO), about 600 million people worldwide get sick and 420,000 die each year from eating contaminated food. Diarrhea is the most common illness caused by consuming contaminated food, with about 550 million cases and 230,000 deaths from diarrhea each year. Children under five years of age account for 40% of the burden of foodborne illness, with 125,000 deaths each year. A 2003 World Health Organization (WHO) report concluded that about 30% of reported food poisoning outbreaks in the WHO European Region occur in private homes. According to the WHO and CDC, in the USA alone, annually, there are 76 million cases of foodborne illness leading to 325,000 hospitalizations and 5,000 deaths. From 2011 to 2016, on average, there were 668,673 cases of foodborne illness and 21 deaths each year. In addition, during this period, 1,007 food poisoning outbreaks with 30,395 cases of food poisoning were reported.

Lifestyle (social sciences)

Lifestyle is the interests, opinions, behaviours, and behavioural orientations of an individual, group, or culture. The term was introduced by Austrian psychologist Alfred Adler in his 1929 book, The Case of Miss R., with the meaning of "a person's basic character as established early in childhood". The broader sense of lifestyle as a "way or style of living" has been documented since 1961. Lifestyle is a combination of determining intangible or tangible factors. Tangible factors relate specifically to demographic variables, i.e. an individual's demographic profile, whereas intangible factors concern the psychological aspects of an individual such as personal values, preferences, and outlooks. A rural environment has different lifestyles compared to an urban metropolis. Location is important even within an urban scope. The nature of the neighborhood in which a person resides affects the set of lifestyles available to that person due to differences between various neighborhoods' degrees of affluence and proximity to natural and cultural environments. For example, in areas near the sea, a surf culture or lifestyle can often be present. Individual identity A lifestyle typically reflects an individual's attitudes, way of life, values, or world view. Therefore, a lifestyle is a means of forging a sense of self and to create cultural symbols that resonate with personal identity. Not all aspects of a lifestyle are voluntary. Surrounding social and technical systems can constrain the lifestyle choices available to the individual and the symbols they are able to project to others and themself. The lines between personal identity and the everyday doings that signal a particular lifestyle become blurred in modern society. For example, "green lifestyle" means holding beliefs and engaging in activities that consume fewer resources and produce less harmful waste (i.e. a smaller ecological footprint), and deriving a sense of self from holding these beliefs and engaging in these activities. Some commentators argue that, in modernity, the cornerstone of lifestyle construction is consumption behavior, which offers the possibility to create and further individualize the self with different products or services that signal different ways of life. Lifestyle may include views on politics, religion, health, intimacy, and more. All of these aspects play a role in shaping someone's lifestyle. In the magazine and television industries, "lifestyle" is used to describe a category of publications or programs. History of lifestyles studies Three main phases can be identified in the history of lifestyles studies: Lifestyles and social position Earlier studies on lifestyles focus on the analysis of social structure and of the individuals' relative positions inside it. Thorstein Veblen, with his 'emulation' concept, opens this perspective by asserting that people adopt specific 'schemes of life', and in particular specific patterns of 'conspicuous consumption', depending on a desire for distinction from social strata they identify as inferior and a desire for emulation of the ones identified as superior. Max Weber intends lifestyles as distinctive elements of status groups strictly connected with a dialectic of recognition of prestige: the lifestyle is the most visible manifestation of social differentiation, even within the same social class, and in particular it shows the prestige which the individuals believe they enjoy or to which they aspire. Georg Simmel carries out formal analysis of lifestyles, at the heart of which can be found processes of individualisation, identification, differentiation, and recognition, understood both as generating processes of, and effects generated by, lifestyles, operating "vertically" as well as "horizontally". Finally, Pierre Bourdieu renews this approach within a more complex model in which lifestyles, made up mainly of social practices and closely tied to individual tastes, represent the basic point of intersection between the structure of the field and processes connected with the habitus. Lifestyles as styles of thought The approach interpreting lifestyles as principally styles of thought has its roots in the soil of psychological analysis. Initially, starting with Alfred Adler, a lifestyle was understood as a style of personality, in the sense that the framework of guiding values and principles which individuals develop in the first years of life end up defining a system of judgement which informs their actions throughout their lives. Later, particularly in Milton Rokeach's work, Arnold Mitchell's VALS research and Lynn R. Kahle's LOV research, lifestyles' analysis developed as profiles of values, reaching the hypothesis that it is possible to identify various models of scales of values organized hierarchically, to which different population sectors correspond. Then with Daniel Yankelovich and William Wells we move on to the so-called AIO approach in which attitudes, interests and opinions are considered as fundamental lifestyles' components, being analysed from both synchronic and diachronic points of view and interpreted on the basis of socio-cultural trends in a given social context (as, for instance, in Bernard Cathelat's work). Finally, a further development leads to the so-called profiles-and-trends approach, at the core of which is an analysis of the relations between mental and behavioural variables, bearing in mind that socio-cultural trends influence both the diffusion of various lifestyles within a population and the emerging of different modalities of interaction between thought and action. Lifestyles as styles of action Analysis of lifestyles as action profiles is characterized by the fact that it no longer considers the action level as a simple derivative of lifestyles, or at least as their collateral component, but rather as a constitutive element. In the beginning, this perspective focussed mainly on consumer behaviour, seeing products acquired as objects expressing on the material plane individuals' self-image and how they view their position in society. Subsequently, the perspective broadened to focus more generally on the level of daily life, concentrating – as in authors such as Joffre Dumazedier and Anthony Giddens – on the use of time, especially loisirs, and trying to study the interaction between the active dimension of choice and the dimension of routine and structuration which characterize that level of action. Finally, some authors, for instance Richard Jenkins and A. J. Veal, suggested an approach to lifestyles in which it is not everyday actions which make up the plane of analysis but those which the actors who adopt them consider particularly meaningful and distinctive. Health A healthy or unhealthy lifestyle will most likely be transmitted across generations. According to the study done by Case et al. (2002), when a 0-3-year-old child has a mother who practices a healthy lifestyle, this child will be 27% more likely to become healthy and adopt the same lifestyle. For instance, high income parents are more likely to eat more fruit and vegetables, have time to exercise, and provide the best living condition to their children. On the other hand, low-income parents are more likely to participate in unhealthy activities such as smoking to help them release poverty-related stress and depression. Parents are the first teacher for every child. Everything that parents do will be very likely transferred to their children through the learning process. Adults may be drawn together by mutual interest that results in a lifestyle. For example, William Dufty described how pursuing a sugar-free diet led to such associations: Class Lifestyle research can contribute to the question of the relevance of the class concept. Media culture The term lifestyle was introduced in the 1950s as a derivative of that of style in art: Theodor W. Adorno noted that there is a "culture industry" in which the mass media is involved, but that the term "mass culture" is inappropriate: The media culture of advanced capitalism typically creates new "life-styles" to drive the consumption of new commodities: See also Aeromobility Alternative lifestyle Intentional living Life stance Lifestyle brand Lifestyle guru Otium Personal life Sustainable living Simple living Style of life Tao Anthropology References Notes Sources Adorno, Th., "Culture Industry Reconsidered," in Adorno (1991).

Sustainable Development Goal 9

Sustainable Development Goal 9 (Goal 9 or SDG 9) is about "industry, innovation and infrastructure" and is one of the 17 Sustainable Development Goals adopted by the United Nations General Assembly in 2015. SDG 9 aims to build resilient infrastructure, promote sustainable industrialization and foster innovation. SDG 9 has eight targets, and progress is measured by twelve indicators. The first five targets are outcome targets: develop sustainable, resilient and inclusive infrastructures; promote inclusive and sustainable industrialization; increase access to financial services and markets; upgrade all industries and infrastructures for sustainability; enhance research and upgrade industrial technologies. The remaining three targets are means of implementation targets: Facilitate sustainable infrastructure development for developing countries; support domestic technology development and industrial diversification; universal access to information and communications technology. In 2019, it was reported that "the intensity of global carbon dioxide emissions has declined by nearly one quarter since 2000, showing a general decoupling of carbon dioxide emissions from GDP growth". Millions of people are still unable to access the internet due to cost, coverage, and other reasons. It is estimated that just 54% of the world's population are currently (in 2020) internet users. Background The aim of attaining inclusive and sustainable industrialization is to "unleash dynamic and competitive economic forces that generate employment and income". This goal includes striving for resilience (engineering and construction) and urban resilience. SDG 9 recognizes that humanity's ability to connect and communicate effectively, move people and things efficiently, and develop new skills, industries and technology, is crucial in overcoming the many interlinked economic, social and environmental challenges in the 21st century. In order to have a successful community, a functioning and strong infrastructure has to be in place as its basic requirement. SDG 9 is all about promoting innovative and sustainable technologies and ensuring equal and universal access to information and financial markets. The technological development in infrastructure is what gives rise to a sustainable society. This is expected to create prosperity and jobs, and build stable and prosperous societies across the globe. The key emphasis is on developing reliable and sustainable infrastructural solutions that support economic development as well as human well-being, while also ensuring financial affordability. This goal aims at ensuring every society in the world possess good infrastructure. Achieving SDG 9 will require significant financing and political will. Key challenges include improving internet access in developing countries, inadequate transport, (particularly in land-locked developing countries) and the disparity of Research and Development investment and the number of researchers in developing countries when compared to developed countries. Outcome targets SDG 9 is broken down into 8 specific targets to reach the SDG goal. The first five targets are called 'outcome targets' (9.1-9.5), with the last three named 'means of achieving targets' (9.a-9.c). Outcome targets have specific desired outcomes that achieve the objective of the SDG goal. They are as follows: Build resilient infrastructure, promote inclusive and sustainable industrialization, increase access to small scale enterprises, upgrade existing infrastructure, and enhance scientific research. . Each target includes one or more indicators that measure the achieved progress. Target 9.1: Develop sustainable, resilient and inclusive infrastructures Target 9.1 is: "Develop quality, reliable, sustainable and resilient infrastructure, including regional and trans-border infrastructure, to support economic development and human well-being, with a focus on affordable and fair access for all". It has two indicators: "Proportion of the rural population who live within 2 km of an all-season road" "Passenger and freight volumes, by mode of transport" Target 9.2: Promote inclusive and sustainable industrialization Target 9.2 is "Promote inclusive and sustainable industrialization, and by 2030, to raise significantly the industry's share of employment and GDP in line with national circumstances as well as to double its share in least developed countries" It has two indicators: "Manufacturing value added as a proportion of GDP and per capita" "Manufacturing employment as a proportion of total employment" Manufacturing is a major source of employment. In 2016, the least developed countries had less "manufacturing value added per capita." The figure for Europe and North America was US$4,621, compared to about $100 in the least developed countries. The industry employment in the world hasn't drastically changed. In 1991, the industry employment made up around 21% of total employment in the world, while in 2017, the industry employment made up 22% of total employment in the world. Manufacturing employment is growing mostly in developing countries, while it declines in developed countries. In Germany, the manufacturing employment made up 47% of total employment in 1991, while it declined to 27% of total employment in 2017. In Kenya, the manufacturing employment made up 6% of total employment and has grown by two percent points to 8% in 2017. Target 9.3: Increase access to financial services and markets Target 9.3 is: "Increase the access of small-scale industrial and other enterprises, particularly in developing countries, to financial services including affordable credit and their integration into value chains and markets". It has two indicators: "Proportion of small-scale industries in total industry value-added" "Proportion of small-scale industries with a loan or line of credit" According to a UN progress report from 2020, "only 22% of small-scale industries in sub-Saharan Africa received loans or lines of credit, compared with 48% in Latin America and the Caribbean". Target 9.4: Upgrade all industries and infrastructures for sustainability Target 9.4 is: "By 2030, upgrade infrastructure and retrofit industries to make them sustainable, with increased resource-use efficiency and greater adoption of clean and environmentally sound technologies and industrial processes, with all countries taking action in accordance with their respective capabilities". It has only one indicator: "CO2 emissions per unit of value added." According to a UN progress report from 2020, the "intensity of global carbon dioxide emissions has declined by nearly one quarter since 2000, showing a general decoupling of carbon dioxide emissions from GDP growth". Target 9.5: Enhance research and upgrade industrial technologies Target 9.5 is "Enhance scientific research, upgrade the technological capabilities of industrial sectors in all countries, in particular developing countries, including, by 2030, encouraging innovation and substantially increasing the number of research and development workers per 1 million people and public and private research and development spending." It has two indicators: "Research and development expenditure as a proportion of GDP" "Number of Researchers (in full-time equivalent) per million inhabitants" In Europe and North America, the number of researchers per 1 million people jumped to 3,372, and in sub-Saharan Africa, the number of researchers per million inhabitants was closer to 99 By 2018, women represented 33% of all researchers, although data are missing from some of the most populous countries. By 2018, research and development constituted an average 1.79% of the global GDP according to the UNESCO Institute for Statistics. Although research expenditure rose in most regions between 2014 and 2018, 80% of countries still invested less than 1% of GDP in research and development by 2018. The G20 countries still accounted for nine-tenths of research expenditure, researchers, publications and patents. In some cases, the researcher population rose faster than related expenditure, leaving less funding available to each researcher. Commitments to SDG 9.5 have not spurred an increase in reporting of data. On the contrary, a total of 99 countries reported data on domestic investment in research in 2015 but only 69 countries in 2018. Similarly, 59 countries recorded the number of researchers (in full-time equivalents) in 2018, down from 90 countries in 2015. Means of implementation targets Target 9.a: Facilitate sustainable infrastructure development for developing countries Target 9.a is: "Facilitate sustainable and resilient infrastructure development in developing countries through enhanced financial, technological and technical support to African countries, least developed countries, landlocked developing countries and Small Island Developing States." It has one indicator: "Total official international support (official development assistance plus other official flows) to infrastructure". Target 9.b: Support domestic technology development and industrial diversification Target 9.b is: "Support domestic technology development, research and innovation in developing countries, including by ensuring a conducive policy environment for, inter alia, industrial diversification and value addition to commodities". It has one indicator: "Proportion of medium and high-tech industry value added in total value added" Target 9.c: Universal access to information and communications technology Target 9.c is: "Significantly increase access to information and communications technology and strive to provide universal and affordable access to the Internet in least developed countries by 2020". It has one indicator: "Proportion of population covered by a mobile network, by technology" Mobile-cellular signal coverage is this target's indicator and has improved a great deal. In previously "unconnected" areas of the globe, 85 percent of people now live in covered areas. Planet-wide, 95% of the population was covered in 2017. Millions of people are still unable to access the internet due to cost, coverage, and other reasons. It is estimated that just 53% of the world's population are currently internet users. Estimates suggest that by the end of 2020, the world will have reached just 57% global internet use and 23% in least developed countries, missing target 9.c by a wide margin. Challenges COVID-19 Pandemic Even before the COVID-19 pandemic began in 2020, the world manufacturing growth was said to be declining. The pandemic hit industries hard and caused disruptions in value chains of goods and their supply, and has affected the digitization of business and services such as video conferencing, healthcare, teleworking etc. Monitoring High-level progress reports for all the SDGs are published in the form of reports by the United Nations Secretary General, the most recent one is from April 2020.

Feasibility study

A feasibility study is an assessment of the practicality of a project or system. A feasibility study aims to objectively and rationally uncover the strengths and weaknesses of an existing business or proposed venture, opportunities and threats present in the natural environment, the resources required to carry through, and ultimately the prospects for success. In its simplest terms, the two criteria to judge feasibility are cost required and value to be attained. A well-designed feasibility study should provide a historical background of the business or project, a description of the product or service, accounting statements, details of the operations and management, marketing research and policies, financial data, legal requirements and tax obligations. Generally, feasibility studies precede technical development and project implementation. A feasibility study evaluates the project's potential for success; therefore, perceived objectivity is an important factor in the credibility of the study for potential investors and lending institutions. It must therefore be conducted with an objective, unbiased approach to provide information upon which decisions can be based. Formal definition A project feasibility study is a comprehensive report that examines in detail the five frames of analysis of a given project. It also takes into consideration its four Ps, its risks and POVs, and its constraints (calendar, costs, and norms of quality). The goal is to determine whether the project should go ahead, be redesigned, or else abandoned altogether. The five frames of analysis are: The frame of definition; the frame of contextual risks; the frame of potentiality; the parametric frame; the frame of dominant and contingency strategies. The four Ps are traditionally defined as Plan, Processes, People, and Power. The risks are considered to be external to the project (e.g., weather conditions) and are divided in eight categories: (Plan) financial and organizational (e.g., government structure for a private project); (Processes) environmental and technological; (People) marketing and sociocultural; and (Power) legal and political. POVs are Points of Vulnerability: they differ from risks in the sense that they are internal to the project and can be controlled or else eliminated. The constraints are the standard constraints of calendar, costs and norms of quality that can each be objectively determined and measured along the entire project lifecycle. Depending on projects, portions of the study may suffice to produce a feasibility study; smaller projects, for example, may not require an exhaustive environmental assessment. Common factors TELOS is an acronym in project management used to define five areas of feasibility that determine whether a project should run or not. T - Technical — Is the project technically possible? E - Economic — Can the project be afforded? Will it increase profit? L - Legal — Is the project legal? O - Operational — How will the current operations support the change? S - Scheduling — Can the project be done in time? Technical feasibility This assessment is based on an outline design of system requirements, to determine whether the company has the technical expertise to handle completion of the project. When writing a feasibility report, the following should be taken to consideration: A brief description of the business to assess more possible factors which could affect the study The part of the business being examined The human and economic factor The possible solutions to the problem At this level, the concern is whether the proposal is both technically and legally feasible (assuming moderate cost). The technical feasibility assessment is focused on gaining an understanding of the present technical resources of the organization and their applicability to the expected needs of the proposed system. It is an evaluation of the hardware and software and how it meets the need of the proposed system Method of production The selection among a number of methods to produce the same commodity should be undertaken first. Factors that make one method being preferred to other method in agricultural projects are the following: Availability of inputs or raw materials and their quality and prices. Availability of markets for outputs of each method and the expected prices for these outputs. Various efficiency factors such as the expected increase in one additional unit of fertilizer or productivity of a specified crop per one thing Production technique After we determine the appropriate method of production of a commodity, it is necessary to look for the optimal technique to produce this commodity. Project requirements Once the method of production and its technique are determined, technical people have to determine the projects' requirements during the investment and operating periods. These include: Determination of tools and equipment needed for the project such as drinkers and feeders or pumps or pipes ...etc. Determination of projects' requirements of constructions such as buildings, storage, and roads ...etc. in addition to internal designs for these requirements. Determination of projects' requirements of skilled and unskilled labor and managerial and financial labor. Determination of construction period concerning the costs of designs and consultations and the costs of constructions and other tools. Determination of minimum storage of inputs, cash money to cope with operating and contingency costs. Project location The most important factors that determine the selection of project location are the following: Availability of land (proper acreage and reasonable costs). The impact of the project on the environment and the approval of the concerned institutions for license. The costs of transporting inputs and outputs to the project's location (i.e., the distance from the markets). Availability of various services related to the project such as availability of extension services or veterinary or water or electricity or good roads ...etc. Legal feasibility It determines whether the proposed system conflicts with legal requirements, e.g., a data processing system must comply with the local data protection regulations and if the proposed venture is acceptable in accordance to the laws of the land. Operational feasibility study Operational feasibility is the measure of how well a proposed system solves problems and takes advantage of the opportunities identified during scope definition and how it satisfies the requirements identified in the requirements analysis phase of system development. The operational feasibility assessment focuses on the degree to which the proposed development project fits in with the existing business environment and objectives about the development schedule, delivery date, corporate culture and existing business processes. To ensure success, desired operational outcomes must be imparted during design and development. These include such design-dependent parameters as reliability, maintainability, supportability, usability, producibility, disposability, sustainability, affordability, etc. These parameters are required to be considered at the early stages of the design if desired operational behaviours are to be realised. A system design and development requires appropriate and timely application of engineering and management efforts to meet the previously mentioned parameters. A system may serve its intended purpose most effectively when its technical and operating characteristics are engineered into the design. Therefore, operational feasibility is a critical aspect of systems engineering that must be integral to the early design phases. Time feasibility A time feasibility study will take into account the period in which the project is going to take up to its completion. A project will fail if it takes too long to be completed before it is useful. Typically this means estimating how long the system will take to develop, and if it can be completed in a given time period using some methods like payback period. Time feasibility is a measure of how reasonable the project timetable is. Given our technical expertise, are the project deadlines reasonable? Some projects are initiated with specific deadlines. It is necessary to determine whether the deadlines are mandatory or desirable. Other feasibility factors Resource feasibility Describe how much time is available to build the new system, when it can be built, whether it interferes with normal business operations, type and amount of resources required, dependencies, and developmental procedures with company revenue prospectus. Financial feasibility In case of a new project, financial viability can be judged on the following parameters: Total estimated cost of the project Financing of the project in terms of its capital structure, debt to equity ratio and promoter's share of total cost Existing investment by the promoter in any other business Projected cash flow and profitability The financial viability of a project should provide the following information: Full details of the assets to be financed and how liquid those assets are. Rate of conversion to cash-liquidity (i.e., how easily the various assets can be converted to cash). Project's funding potential and repayment terms. Sensitivity in the repayments capability to the following factors: Mild slowing of sales. Acute reduction/slowing of sales. Small increase in cost. Large increase in cost. Adverse economic conditions. In 1983 the first generation of the Computer Model for Feasibility Analysis and Reporting (COMFAR), a computation tool for financial analysis of investments, was released. Since then, this United Nations Industrial Development Organization (UNIDO) software has been developed to also support the economic appraisal of projects. The COMFAR III Expert is intended as an aid in the analysis of investment projects. The main module of the program accepts financial and economic data, produces financial and economic statements and graphical displays and calculates measures of performance. Supplementary modules assist in the analytical process. Cost-benefit and value-added methods of economic analysis developed by UNIDO are included in the program and the methods of major international development institutions are accommodated. The program is applicable for the analysis of investment in new projects and expansion or rehabilitation of existing enterprises as, e.g., in the case of reprivatisation projects. For joint ventures, the financial perspective of each partner or class of shareholder can be developed. Analysis can be performed under a variety of assumptions concerning inflation, currency revaluation and price escalations. Market research Market research studies is one of the most important sections of the feasibility study as it examines the marketability of the product or service and convinces readers that there is a potential market for the product or service. If a significant market for the product or services cannot be established, then there is no project. Typically, market studies will assess the potential sales of the product, absorption and market capture rates and the project's timing. The feasibility study outputs the feasibility study report, a report detailing the evaluation criteria, the study findings, and the recommendations.

Stewardship

Stewardship is a practice committed to ethical value that embodies the responsible planning and management of resources. The concepts of stewardship can be applied to the environment and nature, economics, health, places, property, information, theology, and cultural resources. Etymology Stewardship was originally made up of the tasks of a domestic steward, from stiġ (house, hall) and weard, (ward, guard, guardian, keeper). In the beginning, it referred to the household servant's duties for bringing food and drink to the castle's dining hall. Stewardship responsibilities were eventually expanded to include the domestic, service and management needs of the entire household. Commercial stewardship tends to the domestic and service requirements of passengers on ships, trains, airplanes or guests in restaurants. This concept of stewardship continues to be referenced within these specific categories. Stewardship is now generally recognized as the acceptance or assignment of responsibility to shepherd and safeguard the valuables of others.

Relativism

Relativism is a family of philosophical views which deny claims to objectivity within a particular domain and assert that valuations in that domain are relative to the perspective of an observer or the context in which they are assessed. There are many different forms of relativism, with a great deal of variation in scope and differing degrees of controversy among them. Moral relativism encompasses the differences in moral judgments among people and cultures. Epistemic relativism holds that there are no absolute principles regarding normative belief, justification, or rationality, and that there are only relative ones. Alethic relativism (also factual relativism) is the doctrine that there are no absolute truths, i.e., that truth is always relative to some particular frame of reference, such as a language or a culture (cultural relativism). Some forms of relativism also bear a resemblance to philosophical skepticism. Descriptive relativism seeks to describe the differences among cultures and people without evaluation, while normative relativism evaluates the word truthfulness of views within a given framework. Forms of relativism Anthropological versus philosophical relativism Anthropological relativism refers to a methodological stance, in which the researcher suspends (or brackets) their own cultural prejudice while trying to understand beliefs or behaviors in their contexts. This has become known as methodological relativism, and concerns itself specifically with avoiding ethnocentrism or the application of one's own cultural standards to the assessment of other cultures. This is also the basis of the so-called "emic" and "etic" distinction, in which: An emic or insider account of behavior is a description of a society in terms that are meaningful to the participant or actor's own culture; an emic account is therefore culture-specific, and typically refers to what is considered "common sense" within the culture under observation. An etic or outsider account is a description of a society by an observer, in terms that can be applied to other cultures; that is, an etic account is culturally neutral, and typically refers to the conceptual framework of the social scientist. (This is complicated when it is scientific research itself that is under study, or when there is theoretical or terminological disagreement within the social sciences.) Philosophical relativism, in contrast, asserts that the truth of a proposition depends on the metaphysical, or theoretical frame, or the instrumental method, or the context in which the proposition is expressed, or on the person, groups, or culture who interpret the proposition. Methodological relativism and philosophical relativism can exist independently from one another, but most anthropologists base their methodological relativism on that of the philosophical variety. Descriptive versus normative relativism The concept of relativism also has importance both for philosophers and for anthropologists in another way. In general, anthropologists engage in descriptive relativism ("how things are" or "how things seem"), whereas philosophers engage in normative relativism ("how things ought to be"), although there is some overlap (for example, descriptive relativism can pertain to concepts, normative relativism to truth). Descriptive relativism assumes that certain cultural groups have different modes of thought, standards of reasoning, and so forth, and it is the anthropologist's task to describe, but not to evaluate the validity of these principles and practices of a cultural group. It is possible for an anthropologist in his or her fieldwork to be a descriptive relativist about some things that typically concern the philosopher (e.g., ethical principles) but not about others (e.g., logical principles). However, the descriptive relativist's empirical claims about epistemic principles, moral ideals and the like are often countered by anthropological arguments that such things are universal, and much of the recent literature on these matters is explicitly concerned with the extent of, and evidence for, cultural or moral or linguistic or human universals. The fact that the various species of descriptive relativism are empirical claims may tempt the philosopher to conclude that they are of little philosophical interest, but there are several reasons why this is not so. First, some philosophers, notably Kant, argue that certain sorts of cognitive differences between human beings (or even all rational beings) are impossible, so such differences could never be found to obtain in fact, an argument that places a priori limits on what empirical inquiry could discover and on what versions of descriptive relativism could be true. Second, claims about actual differences between groups play a central role in some arguments for normative relativism (for example, arguments for normative ethical relativism often begin with claims that different groups in fact have different moral codes or ideals). Finally, the anthropologist's descriptive account of relativism helps to separate the fixed aspects of human nature from those that can vary, and so a descriptive claim that some important aspect of experience or thought does (or does not) vary across groups of human beings tells us something important about human nature and the human condition. Normative relativism concerns normative or evaluative claims that modes of thought, standards of reasoning, or the like are only right or wrong relative to a framework. 'Normative' is meant in a general sense, applying to a wide range of views; in the case of beliefs, for example, normative correctness equals truth. This does not mean, of course, that framework-relative correctness or truth is always clear, the first challenge being to explain what it amounts to in any given case (e.g., with respect to concepts, truth, epistemic norms). Normative relativism (say, in regard to normative ethical relativism) therefore implies that things (say, ethical claims) are not simply true in themselves, but only have truth values relative to broader frameworks (say, moral codes). (Many normative ethical relativist arguments run from premises about ethics to conclusions that assert the relativity of truth values, bypassing general claims about the nature of truth, but it is often more illuminating to consider the type of relativism under question directly.) Legal relativism In English common law, two (perhaps three) separate standards of proof are recognized: proof based on the balance of probabilities is the lesser standard used in civil litigation, which cases mostly concern money or some other penalty, that, if further and better evidence should emerge, is reasonably reversible. proof beyond reasonable doubt is used in criminal law cases where an accused's right to personal freedom or survival is in question, because such punishment is not reasonably reversible. Absolute truth is so complex as to be only capable of being fully understood by the omniscient established during the Tudor period as the one true God Related and contrasting positions Relationism is the theory that there are only relations between individual entities, and no intrinsic properties. Despite the similarity in name, it is held by some to be a position distinct from relativism—for instance, because "statements about relational properties [...] assert an absolute truth about things in the world". On the other hand, others wish to equate relativism, relationism and even relativity, which is a precise theory of relationships between physical objects: Nevertheless, "This confluence of relativity theory with relativism became a strong contributing factor in the increasing prominence of relativism". Whereas previous investigations of science only sought sociological or psychological explanations of failed scientific theories or pathological science, the 'strong programme' is more relativistic, assessing scientific truth and falsehood equally in a historic and cultural context. Criticisms A common argument against relativism suggests that it inherently refutes itself: the statement "all is relative" classes either as a relative statement or as an absolute one. If it is relative, then this statement does not rule out absolutes. If the statement is absolute, on the other hand, then it provides an example of an absolute statement, proving that not all truths are relative. However, this argument against relativism only applies to relativism that positions truth as relative–i.e. epistemological/truth-value relativism. More specifically, it is only extreme forms of epistemological relativism that can come in for this criticism as there are many epistemological relativists who posit that some aspects of what is regarded as factually "true" are not universal, yet still accept that other universal truths exist (e.g. gas laws or moral laws). Another argument against relativism posits a Natural Law. Simply put, the physical universe works under basic principles: the "Laws of Nature". Some contend that a natural Moral Law may also exist, for example as argued by, Immanuel Kant in Critique of Practical Reason, Richard Dawkins in The God Delusion (2006) and addressed by C. S. Lewis in Mere Christianity (1952). Dawkins said "I think we face an equal but much more sinister challenge from the left, in the shape of cultural relativism - the view that scientific truth is only one kind of truth and it is not to be especially privileged". Philosopher Hilary Putnam, among others, states that some forms of relativism make it impossible to believe one is in error. If there is no truth beyond an individual's belief that something is true, then an individual cannot hold their own beliefs to be false or mistaken. A related criticism is that relativizing truth to individuals destroys the distinction between truth and belief. Views Philosophical Ancient Sophism Sophists are considered the founding fathers of relativism in Western philosophy. Elements of relativism emerged among the Sophists in the 5th century BC. Notably, it was Protagoras who coined the phrase, "Man is the measure of all things: of things which are, that they are, and of things which are not, that they are not." The thinking of the Sophists is mainly known through their opponent, Plato. In a paraphrase from Plato's dialogue Theaetetus, Protagoras said: "What is true for you is true for you, and what is true for me is true for me." Modern Bernard Crick Bernard Crick, a British political scientist and advocate of relativism, suggested in In Defence of Politics (1962) that moral conflict between people is inevitable. He thought that only ethics can resolve such conflict, and when that occurs in public it results in politics. Accordingly, Crick saw the process of dispute resolution, harms reduction, mediation or peacemaking as central to all of moral philosophy. He became an important influence on feminists and later on the Greens. Paul Feyerabend Philosopher of science Paul Feyerabend is often considered to be a relativist, although he denied being one. Feyerabend argued that modern science suffers from being methodologically monistic (the belief that only a single methodology can produce scientific progress). Feyerabend summarises his case in Against Method with the phrase "anything goes". In an aphorism [Feyerabend] often repeated, "potentially every culture is all cultures". This is intended to convey that world views are not hermetically closed, since their leading concepts have an "ambiguity" - better, an open-endedness - which enables people from other cultures to engage with them. [...] It follows that relativism, understood as the doctrine that truth is relative to closed systems, can get no purchase. [...] For Feyerabend, both hermetic relativism and its absolutist rival [realism] serve, in their different ways, to "devalue human existence". The former encourages that unsavoury brand of political correctness which takes the refusal to criticise "other cultures" to the extreme of condoning murderous dictatorship and barbaric practices. The latter, especially in its favoured contemporary form of "scientific realism", with the excessive prestige it affords to the abstractions of "the monster 'science'", is in bed with a politics which likewise disdains variety, richness and everyday individuality - a politics which likewise "hides" its norms behind allegedly neutral facts, "blunts choices and imposes laws". Thomas Kuhn Thomas Kuhn's philosophy of science, as expressed in The Structure of Scientific Revolutions, is often interpreted as relativistic. He claimed that, as well as progressing steadily and incrementally ("normal science"), science undergoes periodic revolutions or "paradigm shifts", leaving scientists working in different paradigms with difficulty in even communicating. Thus the truth of a claim, or the existence of a posited entity, is relative to the paradigm employed. However, it is not necessary for him to embrace relativism because every paradigm presupposes the prior, building upon itself through history and so on. This leads to there being a fundamental, incremental, and referential structure of development which is not relative but again, fundamental. From these remarks, one thing is however certain: Kuhn is not saying that incommensurable theories cannot be compared - what they can't be is compared in terms of a system of common measure. He very plainly says that they can be compared, and he reiterates this repeatedly in later work, in a (mostly in vain) effort to avert the crude and sometimes catastrophic misinterpretations he suffered from mainstream philosophers and post-modern relativists alike. But Kuhn rejected the accusation of being a relativist later in his postscript: scientific development is ... a unidirectional and irreversible process. Later scientific theories are better than earlier ones for solving puzzles ... That is not a relativist's position, and it displays the sense in which I am a convinced believer in scientific progress. Some have argued that one can also read Kuhn's work as essentially positivist in its ontology: the revolutions he posits are epistemological, lurching toward a presumably 'better' understanding of an objective reality through the lens presented by the new paradigm. However, a number of passages in Structure do indeed appear to be distinctly relativist, and to directly challenge the notion of an objective reality and the ability of science to progress towards an ever-greater grasp of it, particularly through the process of paradigm change. In the sciences there need not be progress of another sort. We may, to be more precise, have to relinquish the notion, explicit or implicit, that changes of paradigm carry scientists and those who learn from them closer and closer to the truth. We are all deeply accustomed to seeing science as the one enterprise that draws constantly nearer to some goal set by nature in advance. But need there be any such goal? Can we not account for both science's existence and its success in terms of evolution from the community's state of knowledge at any given time? Does it really help to imagine that there is some one full, objective, true account of nature and that the proper measure of scientific achievement is the extent to which it brings us closer to that ultimate goal? George Lakoff and Mark Johnson George Lakoff and Mark Johnson define relativism in Metaphors We Live By as the rejection of both subjectivism and metaphysical objectivism in order to focus on the relationship between them, i.e. the metaphor by which we relate our current experience to our previous experience. In particular, Lakoff and Johnson characterize "objectivism" as a "straw man", and, to a lesser degree, criticize the views of Karl Popper, Kant and Aristotle. Robert Nozick In his book Invariances, Robert Nozick expresses a complex set of theories about the absolute and the relative. He thinks the absolute/relative distinction should be recast in terms of an invariant/variant distinction, where there are many things a proposition can be invariant with regard to or vary with. He thinks it is coherent for truth to be relative, and speculates that it might vary with time. He thinks necessity is an unobtainable notion, but can be approximated by robust invariance across a variety of conditions—although we can never identify a proposition that is invariant with regard to everything. Finally, he is not particularly warm to one of the most famous forms of relativism, moral relativism, preferring an evolutionary account. Joseph Margolis Joseph Margolis advocates a view he calls "robust relativism" and defends it in his books Historied Thought, Constructed World, Chapter 4 (California, 1995) and The Truth about Relativism (Blackwell, 1991). He opens his account by stating that our logics should depend on what we take to be the nature of the sphere to which we wish to apply our logics. Holding that there can be no distinctions which are not "privileged" between the alethic, the ontic, and the epistemic, he maintains that a many-valued logic just might be the most apt for aesthetics or history since, because in these practices, we are loath to hold to simple binary logic; and he also holds that many-valued logic is relativistic. (This is perhaps an unusual definition of "relativistic". Compare with his comments on "relationism".) To say that "True" and "False" are mutually exclusive and exhaustive judgements on Hamlet, for instance, really does seem absurd. A many-valued logicwith its values "apt", "reasonable", "likely", and so onseems intuitively more applicable to interpreting Hamlet. Where apparent contradictions arise between such interpretations, we might call the interpretations "incongruent", rather than dubbing either of them "false", because using many-valued logic implies that a measured value is a mixture of two extreme possibilities. Using the subset of many-valued logic, fuzzy logic, it can be said that various interpretations can be represented by membership in more than one possible truth set simultaneously. Fuzzy logic is therefore probably the best mathematical structure for understanding "robust relativism" and has been interpreted by Bart Kosko as philosophically being related to Zen Buddhism. It was Aristotle who held that relativism implies that we should, sticking with appearances only, end up contradicting ourselves somewhere if we could apply all attributes to all ousiai (beings). Aristotle, however, made non-contradiction dependent upon his essentialism. If his essentialism is false, then so too is his ground for disallowing relativism. (Subsequent philosophers have found other reasons for supporting the principle of non-contradiction.) Beginning with Protagoras and invoking Charles Sanders Peirce, Margolis shows that the historic struggle to discredit relativism is an attempt to impose an unexamined belief in the world's essentially rigid rule-like nature. Plato and Aristotle merely attacked "relationalism"the doctrine of true for l or true for k, and the like, where l and k are different speakers or different worldsor something similar (most philosophers would call this position "relativism"). For Margolis, "true" means true; that is, the alethic use of "true" remains untouched. However, in real world contexts, and context is ubiquitous in the real world, we must apply truth values. Here, in epistemic terms, we might tout court retire "true" as an evaluation and keep "false". The rest of our value-judgements could be graded from "extremely plausible" down to "false". Judgements which on a bivalent logic would be incompatible or contradictory are further seen as "incongruent", although one may well have more weight than the other. In short, relativistic logic is not, or need not be, the bugbear it is often presented to be. It may simply be the best type of logic to apply to certain very uncertain spheres of real experiences in the world (although some sort of logic needs to be applied in order to make that judgement). Those who swear by bivalent logic might simply be the ultimate keepers of the great fear of the flux. Richard Rorty Philosopher Richard Rorty has a somewhat paradoxical role in the debate over relativism: he is criticized for his relativistic views by many commentators, but has always denied that relativism applies to much anybody, being nothing more than a Platonic scarecrow. Rorty claims, rather, that he is a pragmatist, and that to construe pragmatism as relativism is to beg the question. '"Relativism" is the traditional epithet applied to pragmatism by realists' '"Relativism" is the view that every belief on a certain topic, or perhaps about any topic, is as good as every other. No one holds this view. Except for the occasional cooperative freshman, one cannot find anybody who says that two incompatible opinions on an important topic are equally good. The philosophers who get called 'relativists' are those who say that the grounds for choosing between such opinions are less algorithmic than had been thought.' 'In short, my strategy for escaping the self-referential difficulties into which "the Relativist" keeps getting himself is to move everything over from epistemology and metaphysics into cultural politics, from claims to knowledge and appeals to self-evidence to suggestions about what we should try.' Rorty takes a deflationary attitude to truth, believing there is nothing of interest to be said about truth in general, including the contention that it is generally subjective. He also argues that the notion of warrant or justification can do most of the work traditionally assigned to the concept of truth, and that justification is relative; justification is justification to an audience, for Rorty. In Contingency, Irony, and Solidarity he argues that the debate between so-called relativists and so-called objectivists is beside the point because they do not have enough premises in common for either side to prove anything to the other. Nalin de Silva In his book Mage Lokaya (My World), 1986, Nalin de Silva criticized the basis of the established western system of knowledge, and its propagation, which he refers as "domination throughout the world".He explained in this book that mind independent reality is impossible and knowledge is not found but constructed. Further he has introduced and developed the concept of "Constructive Relativism" as the basis on which knowledge is constructed relative to the sense organs, culture and the mind completely based on Avidya. Colin Murray Turbayne In his final book Metaphors for the Mind: The Creative Mind and Its Origins (1991), Colin Murray Turbayne joins the debate about relativism and realism by providing an analysis of the manner in which Platonic metaphors which were first presented in the procreation model of the Timaeus dialogue have evolved over time to influence the philosophical works of both George Berkeley and Emmanuel Kant. In addition, he illustrates the manner in which these ancient Greek metaphors have subsequently evolved to impact the development of the theories of "substance" and "attribute", which in turn have dominated the development of human thought and language in the 20th century. In his The Myth of Metaphor (1962) Turbayne argues that it is perfectly possible to transcend the limitations which are inherent in such metaphors, including those incorporated within the framework of classical "objective" mechanistic Newtonian cosmology and scientific materialism in general. In Turbayne's view, one can strive to embrace a more satisfactory epistemology by first acknowledging the limitations imposed by such metaphorical systems. This can readily be accomplished by restoring Plato's metaphorical model to its original state in which both "male" and "female" aspects of the mind work in concert within the context of a harmonious balance during the process of creation. Postmodernism The term "relativism" often comes up in debates over postmodernism, poststructuralism and phenomenology. Critics of these perspectives often identify advocates with the label "relativism". For example, the Sapir–Whorf hypothesis is often considered a relativist view because it posits that linguistic categories and structures shape the way people view the world. Stanley Fish has defended postmodernism and relativism. These perspectives do not strictly count as relativist in the philosophical sense, because they express agnosticism on the nature of reality and make epistemological rather than ontological claims. Nevertheless, the term is useful to differentiate them from realists who believe that the purpose of philosophy, science, or literary critique is to locate externally true meanings. Important philosophers and theorists such as Michel Foucault, Max Stirner, political movements such as post-anarchism or post-Marxism can also be considered as relativist in this sense - though a better term might be social constructivist. The spread and popularity of this kind of "soft" relativism varies between academic disciplines. It has wide support in anthropology and has a majority following in cultural studies. It also has advocates in political theory and political science, sociology, and continental philosophy (as distinct from Anglo-American analytical philosophy). It has inspired empirical studies of the social construction of meaning such as those associated with labelling theory, which defenders can point to as evidence of the validity of their theories (albeit risking accusations of performative contradiction in the process). Advocates of this kind of relativism often also claim that recent developments in the natural sciences, such as Heisenberg's uncertainty principle, quantum mechanics, chaos theory and complexity theory show that science is now becoming relativistic. However, many scientists who use these methods continue to identify as realist or post-positivist, and some sharply criticize the association. Religious Buddhism Madhyamaka Buddhism, which forms the basis for many Mahayana Buddhist schools and which was founded by Nāgārjuna. Nāgārjuna taught the idea of relativity. In the Ratnāvalī, he gives the example that shortness exists only in relation to the idea of length. The determination of a thing or object is only possible in relation to other things or objects, especially by way of contrast. He held that the relationship between the ideas of "short" and "long" is not due to intrinsic nature (svabhāva). This idea is also found in the Pali Nikāyas and Chinese Āgamas, in which the idea of relativity is expressed similarly: "That which is the element of light ... is seen to exist on account of [in relation to] darkness; that which is the element of good is seen to exist on account of bad; that which is the element of space is seen to exist on account of form." Madhyamaka Buddhism discerns two levels of truth: relative and ultimate. The two truths doctrine states that there are Relative or conventional, common-sense truth, which describes our daily experience of a concrete world, and Ultimate truth, which describes the ultimate reality as sunyata, empty of concrete and inherent characteristics. Conventional truth may be understood, in contrast, as "obscurative truth" or "that which obscures the true nature". It is constituted by the appearances of mistaken awareness. Conventional truth would be the appearance that includes a duality of apprehender and apprehended, and objects perceived within that. Ultimate truth is the phenomenal world free from the duality of apprehender and apprehended. Catholicism The Catholic Church, especially under John Paul II and Pope Benedict XVI, has identified relativism as one of the most significant problems for faith and morals today. According to the Church and to some theologians, relativism, as a denial of absolute truth, leads to moral license and a denial of the possibility of sin and of God. Whether moral or epistemological, relativism constitutes a denial of the capacity of the human mind and reason to arrive at truth. Truth, according to Catholic theologians and philosophers (following Aristotle) consists of adequatio rei et intellectus, the correspondence of the mind and reality. Another way of putting it states that the mind has the same form as reality. This means when the form of the computer in front of someone (the type, color, shape, capacity, etc.) is also the form that is in their mind, then what they know is true because their mind corresponds to objective reality. The denial of an absolute reference, of an axis mundi, denies God, who equates to Absolute Truth, according to these Christian theologians. They link relativism to secularism, an obstruction of religion in human life. Leo XIII Pope Leo XIII (1810–1903) was the first known Pope to use the word "relativism", in his encyclical Humanum genus (1884). Leo condemned Freemasonry and claimed that its philosophical and political system was largely based on relativism. John Paul II John Paul II wrote in Veritatis Splendor As is immediately evident, the crisis of truth is not unconnected with this development. Once the idea of a universal truth about the good, knowable by human reason, is lost, inevitably the notion of conscience also changes. Conscience is no longer considered in its primordial reality as an act of a person's intelligence, the function of which is to apply the universal knowledge of the good in a specific situation and thus to express a judgment about the right conduct to be chosen here and now. Instead, there is a tendency to grant to the individual conscience the prerogative of independently determining the criteria of good and evil and then acting accordingly. Such an outlook is quite congenial to an individualist ethic, wherein each individual is faced with his own truth, different from the truth of others. Taken to its extreme consequences, this individualism leads to a denial of the very idea of human nature. In Evangelium Vitae (The Gospel of Life), he says: Freedom negates and destroys itself, and becomes a factor leading to the destruction of others, when it no longer recognizes and respects its essential link with the truth. When freedom, out of a desire to emancipate itself from all forms of tradition and authority, shuts out even the most obvious evidence of an objective and universal truth, which is the foundation of personal and social life, then the person ends up by no longer taking as the sole and indisputable point of reference for his own choices the truth about good and evil, but only his subjective and changeable opinion or, indeed, his selfish interest and whim. Benedict XVI In April 2005, in his homily during Mass prior to the conclave which would elect him as Pope, then Cardinal Joseph Ratzinger talked about the world "moving towards a dictatorship of relativism": How many winds of doctrine we have known in recent decades, how many ideological currents, how many ways of thinking. The small boat of thought of many Christians has often been tossed about by these waves – thrown from one extreme to the other: from Marxism to liberalism, even to libertinism; from collectivism to radical individualism; from atheism to a vague religious mysticism; from agnosticism to syncretism, and so forth. Every day new sects are created and what Saint Paul says about human trickery comes true, with cunning which tries to draw those into error (cf Ephesians 4, 14). Having a clear Faith, based on the Creed of the Church, is often labeled today as a fundamentalism. Whereas, relativism, which is letting oneself be tossed and "swept along by every wind of teaching", looks like the only attitude acceptable to today's standards. We are moving towards a dictatorship of relativism which does not recognize anything as certain and which has as its highest goal one's own ego and one's own desires. However, we have a different goal: the Son of God, true man. He is the measure of true humanism. Being an "Adult" means having a faith which does not follow the waves of today's fashions or the latest novelties. A faith which is deeply rooted in friendship with Christ is adult and mature. It is this friendship which opens us up to all that is good and gives us the knowledge to judge true from false, and deceit from truth. On June 6, 2005, Pope Benedict XVI told educators: Today, a particularly insidious obstacle to the task of education is the massive presence in our society and culture of that relativism which, recognizing nothing as definitive, leaves as the ultimate criterion only the self with its desires. And under the semblance of freedom it becomes a prison for each one, for it separates people from one another, locking each person into his or her own 'ego'. Then during the World Youth Day in August 2005, he also traced to relativism the problems produced by the communist and sexual revolutions, and provided a counter-counter argument. In the last century we experienced revolutions with a common programme–expecting nothing more from God, they assumed total responsibility for the cause of the world in order to change it. And this, as we saw, meant that a human and partial point of view was always taken as an absolute guiding principle. Absolutizing what is not absolute but relative is called totalitarianism. It does not liberate man, but takes away his dignity and enslaves him. It is not ideologies that save the world, but only a return to the living God, our Creator, the Guarantor of our freedom, the Guarantor of what is really good and true. Pope Francis Pope Francis refers in Evangelii gaudium to two forms of relativism, "doctrinal relativism" and a "practical relativism" typical of "our age". The latter is allied to "widespread indifference" to systems of belief. Jainism Mahavira (599-527 BC), the 24th Tirthankara of Jainism, developed a philosophy known as Anekantavada. John Koller describes anekāntavāda as "epistemological respect for view of others" about the nature of existence, whether it is "inherently enduring or constantly changing", but "not relativism; it does not mean conceding that all arguments and all views are equal". Sikhism In Sikhism the Gurus (spiritual teachers) have propagated the message of "many paths" leading to the one God and ultimate salvation for all souls who tread on the path of righteousness. They have supported the view that proponents of all faiths can, by doing good and virtuous deeds and by remembering the Lord, certainly achieve salvation. The students of the Sikh faith are told to accept all leading faiths as possible vehicles for attaining spiritual enlightenment provided the faithful study, ponder and practice the teachings of their prophets and leaders. The holy book of the Sikhs called the Sri Guru Granth Sahib says: "Do not say that the Vedas, the Bible and the Koran are false. Those who do not contemplate them are false." Guru Granth Sahib page 1350; later stating: "The seconds, minutes, and hours, days, weeks and months, and the various seasons originate from the one Sun; O nanak, in just the same way, the many forms originate from the Creator." Guru Granth Sahib page 12,13.

Biotechnology

Biotechnology is a multidisciplinary field that involves the integration of natural sciences and engineering sciences in order to achieve the application of organisms and parts thereof for products and services. The term biotechnology was first used by Károly Ereky in 1919 to refer to the production of products from raw materials with the aid of living organisms. The core principle of biotechnology involves harnessing biological systems and organisms, such as bacteria, yeast, and plants, to perform specific tasks or produce valuable substances. Biotechnology had a significant impact on many areas of society, from medicine to agriculture to environmental science. One of the key techniques used in biotechnology is genetic engineering, which allows scientists to modify the genetic makeup of organisms to achieve desired outcomes. This can involve inserting genes from one organism into another, and consequently, create new traits or modifying existing ones. Other important techniques used in biotechnology include tissue culture, which allows researchers to grow cells and tissues in the lab for research and medical purposes, and fermentation, which is used to produce a wide range of products such as beer, wine, and cheese. The applications of biotechnology are diverse and have led to the development of essential products like life-saving drugs, biofuels, genetically modified crops, and innovative materials. It has also been used to address environmental challenges, such as developing biodegradable plastics and using microorganisms to clean up contaminated sites. Biotechnology is a rapidly evolving field with significant potential to address pressing global challenges and improve the quality of life for people around the world; however, despite its numerous benefits, it also poses ethical and societal challenges, such as questions around genetic modification and intellectual property rights. As a result, there is ongoing debate and regulation surrounding the use and application of biotechnology in various industries and fields. Definition The concept of biotechnology encompasses a wide range of procedures for modifying living organisms for human purposes, going back to domestication of animals, cultivation of plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering, as well as cell and tissue culture technologies. The American Chemical Society defines biotechnology as the application of biological organisms, systems, or processes by various industries to learning about the science of life and the improvement of the value of materials and organisms, such as pharmaceuticals, crops, and livestock. As per the European Federation of Biotechnology, biotechnology is the integration of natural science and organisms, cells, parts thereof, and molecular analogues for products and services. Biotechnology is based on the basic biological sciences (e.g., molecular biology, biochemistry, cell biology, embryology, genetics, microbiology) and conversely provides methods to support and perform basic research in biology. Biotechnology is the research and development in the laboratory using bioinformatics for exploration, extraction, exploitation, and production from any living organisms and any source of biomass by means of biochemical engineering where high value-added products could be planned (reproduced by biosynthesis, for example), forecasted, formulated, developed, manufactured, and marketed for the purpose of sustainable operations (for the return from bottomless initial investment on R & D) and gaining durable patents rights (for exclusives rights for sales, and prior to this to receive national and international approval from the results on animal experiment and human experiment, especially on the pharmaceutical branch of biotechnology to prevent any undetected side-effects or safety concerns by using the products). The utilization of biological processes, organisms or systems to produce products that are anticipated to improve human lives is termed biotechnology. By contrast, bioengineering is generally thought of as a related field that more heavily emphasizes higher systems approaches (not necessarily the altering or using of biological materials directly) for interfacing with and utilizing living things. Bioengineering is the application of the principles of engineering and natural sciences to tissues, cells, and molecules. This can be considered as the use of knowledge from working with and manipulating biology to achieve a result that can improve functions in plants and animals. Relatedly, biomedical engineering is an overlapping field that often draws upon and applies biotechnology (by various definitions), especially in certain sub-fields of biomedical or chemical engineering such as tissue engineering, biopharmaceutical engineering, and genetic engineering. History Although not normally what first comes to mind, many forms of human-derived agriculture clearly fit the broad definition of "utilizing a biotechnological system to make products". Indeed, the cultivation of plants may be viewed as the earliest biotechnological enterprise. Agriculture has been theorized to have become the dominant way of producing food since the Neolithic Revolution. Through early biotechnology, the earliest farmers selected and bred the best-suited crops (e.g., those with the highest yields) to produce enough food to support a growing population. As crops and fields became increasingly large and difficult to maintain, it was discovered that specific organisms and their by-products could effectively fertilize, restore nitrogen, and control pests. Throughout the history of agriculture, farmers have inadvertently altered the genetics of their crops through introducing them to new environments and breeding them with other plants — one of the first forms of biotechnology. These processes also were included in early fermentation of beer. These processes were introduced in early Mesopotamia, Egypt, China and India, and still use the same basic biological methods. In brewing, malted grains (containing enzymes) convert starch from grains into sugar and then adding specific yeasts to produce beer. In this process, carbohydrates in the grains broke down into alcohols, such as ethanol. Later, other cultures produced the process of lactic acid fermentation, which produced other preserved foods, such as soy sauce. Fermentation was also used in this time period to produce leavened bread. Although the process of fermentation was not fully understood until Louis Pasteur's work in 1857, it is still the first use of biotechnology to convert a food source into another form. Before the time of Charles Darwin's work and life, animal and plant scientists had already used selective breeding. Darwin added to that body of work with his scientific observations about the ability of science to change species. These accounts contributed to Darwin's theory of natural selection. For thousands of years, humans have used selective breeding to improve the production of crops and livestock to use them for food. In selective breeding, organisms with desirable characteristics are mated to produce offspring with the same characteristics. For example, this technique was used with corn to produce the largest and sweetest crops. In the early twentieth century scientists gained a greater understanding of microbiology and explored ways of manufacturing specific products. In 1917, Chaim Weizmann first used a pure microbiological culture in an industrial process, that of manufacturing corn starch using Clostridium acetobutylicum, to produce acetone, which the United Kingdom desperately needed to manufacture explosives during World War I. Biotechnology has also led to the development of antibiotics. In 1928, Alexander Fleming discovered the mold Penicillium. His work led to the purification of the antibiotic compound formed by the mold by Howard Florey, Ernst Boris Chain and Norman Heatley – to form what we today know as penicillin. In 1940, penicillin became available for medicinal use to treat bacterial infections in humans. The field of modern biotechnology is generally thought of as having been born in 1971 when Paul Berg's (Stanford) experiments in gene splicing had early success. Herbert W. Boyer (Univ. Calif. at San Francisco) and Stanley N. Cohen (Stanford) significantly advanced the new technology in 1972 by transferring genetic material into a bacterium, such that the imported material would be reproduced. The commercial viability of a biotechnology industry was significantly expanded on June 16, 1980, when the United States Supreme Court ruled that a genetically modified microorganism could be patented in the case of Diamond v. Chakrabarty. Indian-born Ananda Chakrabarty, working for General Electric, had modified a bacterium (of the genus Pseudomonas) capable of breaking down crude oil, which he proposed to use in treating oil spills. (Chakrabarty's work did not involve gene manipulation but rather the transfer of entire organelles between strains of the Pseudomonas bacterium). The MOSFET invented at Bell Labs between 1955 and 1960, Two years later, Leland C. Clark and Champ Lyons invented the first biosensor in 1962. Biosensor MOSFETs were later developed, and they have since been widely used to measure physical, chemical, biological and environmental parameters. The first BioFET was the ion-sensitive field-effect transistor (ISFET), invented by Piet Bergveld in 1970. It is a special type of MOSFET, where the metal gate is replaced by an ion-sensitive membrane, electrolyte solution and reference electrode. The ISFET is widely used in biomedical applications, such as the detection of DNA hybridization, biomarker detection from blood, antibody detection, glucose measurement, pH sensing, and genetic technology. By the mid-1980s, other BioFETs had been developed, including the gas sensor FET (GASFET), pressure sensor FET (PRESSFET), chemical field-effect transistor (ChemFET), reference ISFET (REFET), enzyme-modified FET (ENFET) and immunologically modified FET (IMFET). By the early 2000s, BioFETs such as the DNA field-effect transistor (DNAFET), gene-modified FET (GenFET) and cell-potential BioFET (CPFET) had been developed. A factor influencing the biotechnology sector's success is improved intellectual property rights legislation—and enforcement—worldwide, as well as strengthened demand for medical and pharmaceutical products. Rising demand for biofuels is expected to be good news for the biotechnology sector, with the Department of Energy estimating ethanol usage could reduce U.S. petroleum-derived fuel consumption by up to 30% by 2030. The biotechnology sector has allowed the U.S. farming industry to rapidly increase its supply of corn and soybeans—the main inputs into biofuels—by developing genetically modified seeds that resist pests and drought. By increasing farm productivity, biotechnology boosts biofuel production. Examples Biotechnology has applications in four major industrial areas, including health care (medical), crop production and agriculture, non-food (industrial) uses of crops and other products (e.g., biodegradable plastics, vegetable oil, biofuels), and environmental uses. For example, one application of biotechnology is the directed use of microorganisms for the manufacture of organic products (examples include beer and milk products). Another example is using naturally present bacteria by the mining industry in bioleaching. Biotechnology is also used to recycle, treat waste, clean up sites contaminated by industrial activities (bioremediation), and also to produce biological weapons. A series of derived terms have been coined to identify several branches of biotechnology, for example: Bioinformatics (or "gold biotechnology") is an interdisciplinary field that addresses biological problems using computational techniques, and makes the rapid organization as well as analysis of biological data possible. The field may also be referred to as computational biology, and can be defined as, "conceptualizing biology in terms of molecules and then applying informatics techniques to understand and organize the information associated with these molecules, on a large scale". Bioinformatics plays a key role in various areas, such as functional genomics, structural genomics, and proteomics, and forms a key component in the biotechnology and pharmaceutical sector. Blue biotechnology is based on the exploitation of sea resources to create products and industrial applications. This branch of biotechnology is the most used for the industries of refining and combustion principally on the production of bio-oils with photosynthetic micro-algae. Green biotechnology is biotechnology applied to agricultural processes. An example would be the selection and domestication of plants via micropropagation. Another example is the designing of transgenic plants to grow under specific environments in the presence (or absence) of chemicals. One hope is that green biotechnology might produce more environmentally friendly solutions than traditional industrial agriculture. An example of this is the engineering of a plant to express a pesticide, thereby ending the need of external application of pesticides. An example of this would be Bt corn. Whether or not green biotechnology products such as this are ultimately more environmentally friendly is a topic of considerable debate. It is commonly considered as the next phase of green revolution, which can be seen as a platform to eradicate world hunger by using technologies which enable the production of more fertile and resistant, towards biotic and abiotic stress, plants and ensures application of environmentally friendly fertilizers and the use of biopesticides, it is mainly focused on the development of agriculture. On the other hand, some of the uses of green biotechnology involve microorganisms to clean and reduce waste. Red biotechnology is the use of biotechnology in the medical and pharmaceutical industries, and health preservation. This branch involves the production of vaccines and antibiotics, regenerative therapies, creation of artificial organs and new diagnostics of diseases. As well as the development of hormones, stem cells, antibodies, siRNA and diagnostic tests. White biotechnology, also known as industrial biotechnology, is biotechnology applied to industrial processes. An example is the designing of an organism to produce a useful chemical. Another example is the using of enzymes as industrial catalysts to either produce valuable chemicals or destroy hazardous/polluting chemicals. White biotechnology tends to consume less in resources than traditional processes used to produce industrial goods. "Yellow biotechnology" refers to the use of biotechnology in food production (food industry), for example in making wine (winemaking), cheese (cheesemaking), and beer (brewing) by fermentation. It has also been used to refer to biotechnology applied to insects. This includes biotechnology-based approaches for the control of harmful insects, the characterisation and utilisation of active ingredients or genes of insects for research, or application in agriculture and medicine and various other approaches. Gray biotechnology is dedicated to environmental applications, and focused on the maintenance of biodiversity and the remotion of pollutants. Brown biotechnology is related to the management of arid lands and deserts. One application is the creation of enhanced seeds that resist extreme environmental conditions of arid regions, which is related to the innovation, creation of agriculture techniques and management of resources. Violet biotechnology is related to law, ethical and philosophical issues around biotechnology. Microbial biotechnology has been proposed for the rapidly emerging area of biotechnology applications in space and microgravity (space bioeconomy) Dark biotechnology is the color associated with bioterrorism or biological weapons and biowarfare which uses microorganisms, and toxins to cause diseases and death in humans, livestock and crops. Medicine In medicine, modern biotechnology has many applications in areas such as pharmaceutical drug discoveries and production, pharmacogenomics, and genetic testing (or genetic screening). In 2021, nearly 40% of the total company value of pharmaceutical biotech companies worldwide were active in Oncology with Neurology and Rare Diseases being the other two big applications. Pharmacogenomics (a combination of pharmacology and genomics) is the technology that analyses how genetic makeup affects an individual's response to drugs. Researchers in the field investigate the influence of genetic variation on drug responses in patients by correlating gene expression or single-nucleotide polymorphisms with a drug's efficacy or toxicity. The purpose of pharmacogenomics is to develop rational means to optimize drug therapy, with respect to the patients' genotype, to ensure maximum efficacy with minimal adverse effects. Such approaches promise the advent of "personalized medicine"; in which drugs and drug combinations are optimized for each individual's unique genetic makeup. Biotechnology has contributed to the discovery and manufacturing of traditional small molecule pharmaceutical drugs as well as drugs that are the product of biotechnology – biopharmaceutics. Modern biotechnology can be used to manufacture existing medicines relatively easily and cheaply. The first genetically engineered products were medicines designed to treat human diseases. To cite one example, in 1978 Genentech developed synthetic humanized insulin by joining its gene with a plasmid vector inserted into the bacterium Escherichia coli. Insulin, widely used for the treatment of diabetes, was previously extracted from the pancreas of abattoir animals (cattle or pigs). The genetically engineered bacteria are able to produce large quantities of synthetic human insulin at relatively low cost. Biotechnology has also enabled emerging therapeutics like gene therapy. The application of biotechnology to basic science (for example through the Human Genome Project) has also dramatically improved our understanding of biology and as our scientific knowledge of normal and disease biology has increased, our ability to develop new medicines to treat previously untreatable diseases has increased as well. Genetic testing allows the genetic diagnosis of vulnerabilities to inherited diseases, and can also be used to determine a child's parentage (genetic mother and father) or in general a person's ancestry. In addition to studying chromosomes to the level of individual genes, genetic testing in a broader sense includes biochemical tests for the possible presence of genetic diseases, or mutant forms of genes associated with increased risk of developing genetic disorders. Genetic testing identifies changes in chromosomes, genes, or proteins. Most of the time, testing is used to find changes that are associated with inherited disorders. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person's chance of developing or passing on a genetic disorder. As of 2011 several hundred genetic tests were in use. Since genetic testing may open up ethical or psychological problems, genetic testing is often accompanied by genetic counseling. Agriculture Genetically modified crops ("GM crops", or "biotech crops") are plants used in agriculture, the DNA of which has been modified with genetic engineering techniques. In most cases, the main aim is to introduce a new trait that does not occur naturally in the species. Biotechnology firms can contribute to future food security by improving the nutrition and viability of urban agriculture. Furthermore, the protection of intellectual property rights encourages private sector investment in agrobiotechnology. Examples in food crops include resistance to certain pests, diseases, stressful environmental conditions, resistance to chemical treatments (e.g. resistance to a herbicide), reduction of spoilage, or improving the nutrient profile of the crop. Examples in non-food crops include production of pharmaceutical agents, biofuels, and other industrially useful goods, as well as for bioremediation. Farmers have widely adopted GM technology. Between 1996 and 2011, the total surface area of land cultivated with GM crops had increased by a factor of 94, from . 10% of the world's crop lands were planted with GM crops in 2010. As of 2011, 11 different transgenic crops were grown commercially on in 29 countries such as the US, Brazil, Argentina, India, Canada, China, Paraguay, Pakistan, South Africa, Uruguay, Bolivia, Australia, Philippines, Myanmar, Burkina Faso, Mexico and Spain. Genetically modified foods are foods produced from organisms that have had specific changes introduced into their DNA with the methods of genetic engineering. These techniques have allowed for the introduction of new crop traits as well as a far greater control over a food's genetic structure than previously afforded by methods such as selective breeding and mutation breeding. Commercial sale of genetically modified foods began in 1994, when Calgene first marketed its Flavr Savr delayed ripening tomato. To date most genetic modification of foods have primarily focused on cash crops in high demand by farmers such as soybean, corn, canola, and cotton seed oil. These have been engineered for resistance to pathogens and herbicides and better nutrient profiles. GM livestock have also been experimentally developed; in November 2013 none were available on the market, but in 2015 the FDA approved the first GM salmon for commercial production and consumption. There is a scientific consensus that currently available food derived from GM crops poses no greater risk to human health than conventional food, but that each GM food needs to be tested on a case-by-case basis before introduction. Nonetheless, members of the public are much less likely than scientists to perceive GM foods as safe. The legal and regulatory status of GM foods varies by country, with some nations banning or restricting them, and others permitting them with widely differing degrees of regulation. GM crops also provide a number of ecological benefits, if not used in excess. Insect-resistant crops have proven to lower pesticide usage, therefore reducing the environmental impact of pesticides as a whole. However, opponents have objected to GM crops per se on several grounds, including environmental concerns, whether food produced from GM crops is safe, whether GM crops are needed to address the world's food needs, and economic concerns raised by the fact these organisms are subject to intellectual property law. Biotechnology has several applications in the realm of food security. Crops like Golden rice are engineered to have higher nutritional content, and there is potential for food products with longer shelf lives. Though not a form of agricultural biotechnology, vaccines can help prevent diseases found in animal agriculture. Additionally, agricultural biotechnology can expedite breeding processes in order to yield faster results and provide greater quantities of food. Transgenic biofortification in cereals has been considered as a promising method to combat malnutrition in India and other countries. Industrial Industrial biotechnology (known mainly in Europe as white biotechnology) is the application of biotechnology for industrial purposes, including industrial fermentation. It includes the practice of using cells such as microorganisms, or components of cells like enzymes, to generate industrially useful products in sectors such as chemicals, food and feed, detergents, paper and pulp, textiles and biofuels. In the current decades, significant progress has been done in creating genetically modified organisms (GMOs) that enhance the diversity of applications and economical viability of industrial biotechnology. By using renewable raw materials to produce a variety of chemicals and fuels, industrial biotechnology is actively advancing towards lowering greenhouse gas emissions and moving away from a petrochemical-based economy. Synthetic biology is considered one of the essential cornerstones in industrial biotechnology due to its financial and sustainable contribution to the manufacturing sector. Jointly biotechnology and synthetic biology play a crucial role in generating cost-effective products with nature-friendly features by using bio-based production instead of fossil-based. Synthetic biology can be used to engineer model microorganisms, such as Escherichia coli, by genome editing tools to enhance their ability to produce bio-based products, such as bioproduction of medicines and biofuels. For instance, E. coli and Saccharomyces cerevisiae in a consortium could be used as industrial microbes to produce precursors of the chemotherapeutic agent paclitaxel by applying the metabolic engineering in a co-culture approach to exploit the benefits from the two microbes. Another example of synthetic biology applications in industrial biotechnology is the re-engineering of the metabolic pathways of E. coli by CRISPR and CRISPRi systems toward the production of a chemical known as 1,4-butanediol, which is used in fiber manufacturing. In order to produce 1,4-butanediol, the authors alter the metabolic regulation of the Escherichia coli by CRISPR to induce point mutation in the gltA gene, knockout of the sad gene, and knock-in six genes (cat1, sucD, 4hbd, cat2, bld, and bdh). Whereas CRISPRi system used to knockdown the three competing genes (gabD, ybgC, and tesB) that affect the biosynthesis pathway of 1,4-butanediol. Consequently, the yield of 1,4-butanediol significantly increased from 0.9 to 1.8 g/L. Environmental Environmental biotechnology includes various disciplines that play an essential role in reducing environmental waste and providing environmentally safe processes, such as biofiltration and biodegradation. The environment can be affected by biotechnologies, both positively and adversely. Vallero and others have argued that the difference between beneficial biotechnology (e.g., bioremediation is to clean up an oil spill or hazard chemical leak) versus the adverse effects stemming from biotechnological enterprises (e.g., flow of genetic material from transgenic organisms into wild strains) can be seen as applications and implications, respectively. Cleaning up environmental wastes is an example of an application of environmental biotechnology; whereas loss of biodiversity or loss of containment of a harmful microbe are examples of environmental implications of biotechnology. Many cities have installed CityTrees, which use biotechnology to filter pollutants from urban atmospheres. Regulation The regulation of genetic engineering concerns approaches taken by governments to assess and manage the risks associated with the use of genetic engineering technology, and the development and release of genetically modified organisms (GMO), including genetically modified crops and genetically modified fish. There are differences in the regulation of GMOs between countries, with some of the most marked differences occurring between the US and Europe. Regulation varies in a given country depending on the intended use of the products of the genetic engineering. For example, a crop not intended for food use is generally not reviewed by authorities responsible for food safety. The European Union differentiates between approval for cultivation within the EU and approval for import and processing. While only a few GMOs have been approved for cultivation in the EU a number of GMOs have been approved for import and processing. The cultivation of GMOs has triggered a debate about the coexistence of GM and non-GM crops. Depending on the coexistence regulations, incentives for the cultivation of GM crops differ. Database for the GMOs used in the EU The EUginius (European GMO Initiative for a Unified Database System) database is intended to help companies, interested private users and competent authorities to find precise information on the presence, detection and identification of GMOs used in the European Union. The information is provided in English. Learning In 1988, after prompting from the United States Congress, the National Institute of General Medical Sciences (National Institutes of Health) (NIGMS) instituted a funding mechanism for biotechnology training. Universities nationwide compete for these funds to establish Biotechnology Training Programs (BTPs). Each successful application is generally funded for five years then must be competitively renewed. Graduate students in turn compete for acceptance into a BTP; if accepted, then stipend, tuition and health insurance support are provided for two or three years during the course of their PhD thesis work. Nineteen institutions offer NIGMS supported BTPs. Biotechnology training is also offered at the undergraduate level and in community colleges.

Standard of living

Standard of living is the level of income, comforts and services available to an individual, community or society. A contributing factor to an individual's quality of life, standard of living is generally concerned with objective metrics outside an individual's personal control, such as economic, societal, political, and environmental matters. Individuals or groups use the standard of living to evaluate where to live in the world, or when assessing the success of society. In international law, an "adequate standard of living" was first described in the Universal Declaration of Human Rights and further described in the International Covenant on Economic, Social and Cultural Rights. To evaluate the impact of policy for sustainable development, different disciplines have defined Decent Living Standards in order to evaluate or compare relative living experience. During much of its use in economics, improvements to standard of living was thought to be directly connected to economic growth, increase amount of energy consumption and other materials. However, the IPCC Sixth Assessment Report found that literature demonstrates that improvements in sustainable development practices as well as changes in technological efficiency and energy production and use, allow for a Decent Living Standard for all people without fossil fuels and ~15.3 GJ per capita by the end of the 21st century. This allows for climate change mitigation by demand reduction as well as other sustainable development practices. Factors considered by scholars Standard of living might be evaluated using a number of characteristics including as the quality and availability of employment, real income, disposable income, class disparity, poverty rate, quality and housing affordability, hours of work required to purchase necessities, gross domestic product, inflation rate, amount of leisure time, access to and quality of healthcare, quality and availability of education, literacy rates, life expectancy, occurrence of diseases, cost of goods and services, infrastructure, access to, quality and affordability of public transportation, national economic growth, economic and political stability, freedom, environmental quality, climate and safety. For the purposes of economics, politics and policy, it is usually compared across time or between groups defined by social, economic or geographical parameters. Right to an adequate standard of living Decent living standard The standard of living varies between individuals depending on different aspects of life. The standard of living consists of the individuals having the basics such as food, shelter, social safety and interaction, which all contribute to their wellbeing and what is considered to be a decent living standard. Commentators use a number of different measures and approaches to establish the decent living standard (DLS). The decent living standard revolves around the idea and principle that a majority of the population demand the basics that will allow them to have shelter, food and water; however it is not always able to be maintained for a long period of time. Measurement Standard of living is generally measured by standards such as inflation-adjusted income per person and poverty rate. Other measures such as access and quality of health care, income growth inequality, and educational standards are also used. Examples are access to certain goods (such as the number of refrigerators per 1000 people), or measurement of health such as life expectancy. It is the ease by which people living in a time or place are able to satisfy their needs and/or wants. There is also the biological standard of living, which pertains to how well the human biological organism fares in its socio-economic environment. It is often measured by the height of a population. The idea of a 'standard' may be contrasted with the quality of life, which takes into account not only the material standard of living but also other more intangible aspects that make up human life, such as leisure, safety, cultural resources, social life, physical health, environmental quality issues.

Ethics of technology

The ethics of technology is a sub-field of ethics addressing ethical questions specific to the technology age, the transitional shift in society wherein personal computers and subsequent devices provide for the quick and easy transfer of information. Technology ethics is the application of ethical thinking to growing concerns as new technologies continue to rise in prominence. The topic has evolved as technologies have developed. Technology poses an ethical dilemma on producers and consumers alike. The subject of technoethics, or the ethical implications of technology, have been studied by different philosophers such as Hans Jonas and Mario Bunge. Technoethics Technoethics (TE) is an interdisciplinary research area that draws on theories and methods from multiple knowledge domains (such as communications, social sciences, information studies, technology studies, applied ethics, and philosophy) to provide insights on ethical dimensions of technological systems and practices for advancing a technological society. Technoethics views technology and ethics as socially embedded enterprises and focuses on discovering the ethical uses for technology, protecting against the misuse of technology, and devising common principles to guide new advances in technological development and application to benefit society. Typically, scholars in technoethics have a tendency to conceptualize technology and ethics as interconnected and embedded in life and society. Technoethics denotes a broad range of ethical issues revolving around technology – from specific areas of focus affecting professionals working with technology to broader social, ethical, and legal issues concerning the role of technology in society and everyday life. Technoethical perspectives are constantly in transition as technology advances in areas unseen by creators and as users change the intended uses of new technologies. Humans cannot be separated from these technologies because it is an inherent part of consciousness. The short term and longer term ethical considerations for technologies engage the creator, producer, user, and governments. With the increasing impact emerging technologies have on society, the importance of assessing ethical and social issues constantly becomes more important. While such technologies provide opportunities for novel applications and the potential to transform the society on a global scale, their rise is accompanied by new ethical challenges and problems that must be considered. This becomes more difficult with the increasing pace at which technology is progressing and the increasing impact it has on the societal understanding by seemingly outrunning human control. The concept of technoethics focuses on expanding the knowledge of existing research in the areas of technology and ethics in order to provide a holistic construct for the different aspects and subdisciplines of ethics related to technology-related human activity like economics, politics, globalization, and scientific research. It is also concerned with the rights and responsibilities that designers and developers have regarding the outcomes of the respective technology. This is of particular importance with the emergence of algorithmic technology capable of making decisions autonomously and the related issues of developer or data bias influencing these decisions. To work against the manifestation of these biases, the balance between human and technology accountability for ethical failure has to be carefully evaluated and has shifted the view from technology as a merely positive tool towards the perception of technology as inherently neutral. Technoethics thus has to focus on both sides of the human technology equation when confronted with upcoming technology innovations and applications. With technology continuing to advance over time, there are new technoethical issues that come into play. For instance, discussions on genetically modified organisms (GMOs) have brought about a huge concern for technology, ethics, and safety. There is also a huge question of whether or not artificial intelligence (AI) should be trusted and relied upon. These are just some examples of how the advancements in technology will affect the ethical values of humans in the future. Technoethics finds application in various areas of technology. The following key areas are mentioned in the literature: Computer ethics: Focuses on the use of technology in areas including visual technology, artificial intelligence, and robotics. Engineering ethics: Dealing with professional standards of engineers and their moral responsibilities to the public. Internet ethics and cyberethics: Concerning the guarding against unethical Internet activity. Media and communication technoethics: Concerning ethical issues and responsibilities when using mass media and communication technology. Professional technoethics: Concerning all ethical considerations that revolve around the role of technology within professional conduct like in engineering, journalism, or medicine. Educational technoethics: Concerning the ethical issues and outcomes associated with using technology for educational aims. Biotech ethics: Linked to advances in bioethics and medical ethics like considerations arising in cloning, human genetic engineering, and stem cell research. Environmental technoethics: Concerning technological innovations that impact the environment and life. Nanoethics: Concerning ethical and social issues associated with developments in the alteration of matter at the level of atoms and molecules in various disciplines including computer science, engineering, and biology. Military technoethics: Concerning ethical issues associated with technology use in military action. Definitions Ethics address the issues of what is 'right', what is 'just', and what is 'fair'. Ethics describe moral principles influencing conduct; accordingly, the study of ethics focuses on the actions and values of people in society (what people do and how they believe they should act in the world). Technology is the branch of knowledge that deals with the creation and use of technical means and their interrelation with life, society, and the environment; it may draw upon a variety of fields, including industrial arts, engineering, applied science, and pure science. Technology "is core to human development and a key focus for understanding human life, society and human consciousness." Using theories and methods from multiple domains, technoethics provides insights on ethical aspects of technological systems and practices, examines technology-related social policies and interventions, and provides guidelines for how to ethically use new advancements in technology. Technoethics provides a systems theory and methodology to guide a variety of separate areas of inquiry into human-technological activity and ethics. Moreover, the field unites both technocentric and bio-centric philosophies, providing "conceptual grounding to clarify the role of technology to those affected by it and to help guide ethical problem solving and decision making in areas of activity that rely on technology." As a bio-techno-centric field, technoethics "has a relational orientation to both technology and human activity"; it provides "a system of ethical reference that justifies that profound dimension of technology as a central element in the attainment of a 'finalized' perfection of man." Fundamental problems Technology is merely a tool like a device or gadget. With this thought process of technology just being a device or gadget, it is not possible for technology to possess a moral or ethical quality. Going by this thought process the tool maker or end user would be the one who decides the morality or ethicality behind a device or gadget. "Ethics of technology" refers to two basic subdivisions: The ethics involved in the development of new technology—whether it is always, never, or contextually right or wrong to invent and implement a technological innovation. The ethical questions that are exacerbated by the ways in which technology extends or curtails the power of individuals—how standard ethical questions are changed by the new powers. In the former case, ethics of such things as computer security and computer viruses asks whether the very act of innovation is an ethically right or wrong act. Similarly, does a scientist have an ethical obligation to produce or fail to produce a nuclear weapon? What are the ethical questions surrounding the production of technologies that waste or conserve energy and resources? What are the ethical questions surrounding the production of new manufacturing processes that might inhibit employment, or might inflict suffering in the third world? In the latter case, the ethics of technology quickly break down into the ethics of various human endeavors as they are altered by new technologies. For example, bioethics is now largely consumed with questions that have been exacerbated by the new life-preserving technologies, new cloning technologies, and new technologies for implantation. In law, the right of privacy is being continually attenuated by the emergence of new forms of surveillance and anonymity. The old ethical questions of privacy and free speech are given new shape and urgency in an Internet age. Such tracing devices as RFID, biometric analysis and identification, genetic screening, all take old ethical questions and amplify their significance. As you can see, the fundamental problem is as society produces and advances technology that we use in all areas of our life from work, school, medicine, surveillance, etc. we receive great benefits, but there are underlying costs to these benefits. As technology evolves even more, some of the technological innovations can be seen as inhumane and those same technological innovations can be seen by others as creative, life changing, and innovative. History of technoethics Though the ethical consequences of new technologies have existed since Socrates' attack on writing in Plato's dialogue Phaedrus, the formal field of technoethics had only existed for a few decades. The first traces of TE can be seen in Dewey and Peirce's pragmatism. With the advent of the Industrial Revolution, it was easy to see that technological advances were going to influence human activity. This is why they put emphasis on the responsible use of technology. The term "technoethics" was coined in 1977 by the philosopher Mario Bunge to describe the responsibilities of technologists and scientists to develop ethics as a branch of technology. Bunge argued that the current state of technological progress was guided by ungrounded practices based on limited empirical evidence and trial-and-error learning. He recognized that "the technologist must be held not only technically but also morally responsible for whatever he designs or executes: not only should his artifacts be optimally efficient but, far from being harmful, they should be beneficial, and not only in the short run but also in the long term." He recognized a pressing need in society to create a new field called 'technoethics' to discover rationally grounded rules for guiding science and technological progress. With the spurt in technological advances came technological inquiry. Societal views of technology were changing; people were becoming more critical of the developments that were occurring and scholars were emphasizing the need to understand and to take a deeper look and study the innovations. Associations were uniting scholars from different disciplines to study the various aspects of technology. The main disciplines being philosophy, social sciences and science and technology studies (STS). Though many technologies were already focused on ethics, each technology discipline was separated from each other, despite the potential for the information to intertwine and reinforce itself. As technologies became increasingly developed in each discipline, their ethical implications paralleled their development, and became increasingly complex. Each branch eventually became united, under the term technoethics, so that all areas of technology could be studied and researched based on existing, real-world examples and a variety of knowledge, rather than just discipline-specific knowledge. Technology and ethics Ethics theories Technoethics involves the ethical aspects of technology within a society that is shaped by technology. This brings up a series of social and ethical questions regarding new technological advancements and new boundary crossing opportunities. Before moving forward and attempting to address any ethical questions and concerns, it is important to review the three major ethical theories to develop a perspective foundation: Utilitarianism (Bentham) is an ethical theory which attempts to maximize happiness and reduce suffering for the greatest number of people. Utilitarianism focused on results and consequences rather than rules. Duty ethics (Kant) notes the obligations that one has to society and follows society's universal rules. It focuses on the rightness of actions instead of the consequences, focusing on what an individual should do. Virtue ethics is another main perspective in normative ethics. It highlights the role and virtues that an individual's character contains to be able to determine or evaluate ethical behaviour in society. By practicing honing honest and generous behavior, Aristotle, the philosopher of this theory believes that people will then make the right choice when faced with an ethical decision. Relationship ethics states that care and consideration are both derived from human communication. Therefore, ethical communication is the core substance to maintain healthy relationships. Historical framing of technology – four main periods Greek civilization defined technology as techné. Techné is "the set principles, or rational method, involved in the production of an object or the accomplishment of an end; the knowledge such as principles of method; art." This conceptualization of technology used during the early Greek and Roman period to denote the mechanical arts, construction, and other efforts to create, in Cicero's words, a "second nature" within the natural world. Modern conceptualization of technology as invention materialized in the 17th century in Bacon's futuristic vision of a perfect society governed by engineers and scientists in Saloman's House, to raise the importance of technology in society. The German term "Technik" was used in the 19th-20th century. Technik is the totality of processes, machines, tools and systems employed in the practical arts and Engineering. Webber popularized it when it was used in broader fields. Mumford said it was underlying a civilization. Known as: before 1750: Eotechnic, in 1750-1890: Paleoethnic and in 1890: Neoethnic. Place it at the center of social life in close connection to social progress and societal change. Mumford says that a machine cannot be divorced from its larger social pattern, for it is the pattern that gives it meaning and purpose. Rapid advances in technology provoked a negative reaction from scholars who saw technology as a controlling force in society with the potential to destroy how people live (Technological Determinism). Heidegger warned people that technology was dangerous in that it exerted control over people through its mediating effects, thus limiting authenticity of experience in the world that defines life and gives life meaning. It is an intimate part of the human condition, deeply entrenched in all human history, society and mind. Significant technoethical developments in society Many advancements within the past decades have added to the field of technoethics. There are multiple concrete examples that have illustrated the need to consider ethical dilemmas in relation to technological innovations. Beginning in the 1940s influenced by the British eugenic movement, the Nazis conduct "racial hygiene" experiments causing widespread, global anti-eugenic sentiment. In the 1950s the first satellite Sputnik 1 orbited the Earth, the Obninsk Nuclear Power Plant was the first nuclear power plant to be opened, the American nuclear tests take place. The 1960s brought about the first crewed Moon landing, ARPANET created which leads to the later creation of the Internet, first heart transplantation completed, and the Telstar communications satellite is launched. The 70s, 80s, 90s, 2000s and 2010s also brought multiple developments. Technological consciousness Technological consciousness is the relationship between humans and technology. Technology is seen as an integral component of human consciousness and development. Technology, consciousness and society are intertwined in a relational process of creation that is key to human evolution. Technology is rooted in the human mind, and is made manifest in the world in the form of new understandings and artifacts. The process of technological consciousness frames the inquiry into ethical responsibility concerning technology by grounding technology in human life. The structure of technological consciousness is relational but also situational, organizational, aspectual and integrative. Technological consciousness situates new understandings by creating a context of time and space. As well, technological consciousness organizes disjointed sequences of experience under a sense of unity that allows for a continuity of experience. The aspectual component of technological consciousness recognizes that individuals can only be conscious of aspects of an experience, not the whole thing. For this reason, technology manifests itself in processes that can be shared with others. The integrative characteristics of technological consciousness are assimilation, substitution and conversation. Assimilation allows for unfamiliar experiences to be integrated with familiar ones. Substitution is a metaphorical process allowing for complex experiences to be codified and shared with others — for example, language. Conversation is the sense of an observer within an individual's consciousness, providing stability and a standpoint from which to interact with the process. Misunderstandings of consciousness and technology According to Rocci Luppicini, the common misunderstandings about consciousness and technology are listed as follows. The first misunderstanding is that consciousness is only in the head when according to Luppicini, consciousness is not only in the head meaning that "[c]onsciousness is responsible for the creation of new conscious relations wherever imagined, be it in the head, on the street or in the past." The second misunderstanding is technology is not a part of consciousness. Technology is a part of consciousness as "the conceptualization of technology has gone through drastic changes." The third misunderstanding is that technology controls society and consciousness, by which Luppicini means "that technology is rooted in consciousness as an integral part of mental life for everyone. This understanding will most likely alter how both patients and psychologists deal with the trials and tribunes of living with technology." The last misunderstanding is society controls technology and consciousness. "…(other) accounts fail to acknowledge the complex relational nature of technology as an operation within mind and society. This realization shifts the focus on technology to its origins within the human mind as explained through the theory of technological consciousness." Consciousness (C) is only a part of the head: C is responsible for the creation of new conscious relations Technology (T) is not part of C: Humans cannot be separated from technology T controls society and C: Technology cannot control the mind Society controls T and C: Society fails to take in account the consideration of society shaping what technology gets developed? Types of technology ethics Technology ethics are principles that can be used to govern technology including factors like risk management and individual rights. They are basically used to understand and resolve moral issues that have to do with the development and application of technology of different types. There are many types of technology ethics: Access rights: access to empowering technology as a right Accountability: decisions made for who is responsible when considering success or harm in technological advancements Digital rights: protecting intellectual property rights and privacy rights Environment: how to produce technology that could harm the environment Existential risk: technologies that represent a threat to the global quality of life pertaining to extinction Freedom: technology that is used to control a society raising questions related to freedom and independence Health and safety: health and safety risks that are increased and imposed by technologies Human Enhancement: human genetic engineering and human-machine integration Human judgement: when can decisions be judged by automation and when do they acquire a reasonable human? Over-automation: when does automation decrease quality of life and start affecting society? Precaution principle: Who decides that developing this new technology is safe for the world? Privacy: protection of privacy rights Security: Is due diligence required to ensure information security? Self replicating technology: should self replicating be the norm? Technology transparency: clearly explaining how a technology works and what its intentions are Terms of service: ethics related to legal agreements Ethical challenges Ethical challenges arise in many different situations: Human knowledge processes Workplace discrimination Strained work-life balance in technologically enhanced work environments: Many people find that simply having the technology allowing one to do work while at home increases stress levels. In a recent study 70% of respondents said that since technology, work has crept into their personal lives. Digital divide: Inequalities in information access for parts of the population Unequal opportunities for scientific and technological development Norris says access to information and knowledge resources within a knowledge society tend to favour the economically privileged who have greater access to technological tools needed to access information and knowledge resources disseminated online and the privatization of knowledge Inequality in terms of how scientific and technological knowledge is developed around the globe. Developing countries do not have the same opportunities as developed countries to invest in costly large-scale research and expensive research facilities and instrumentation Organizational responsibility and accountability issues Intellectual property ownership issues Information overload: Information processing theory asserts that working memory that has a limited capacity and too much information can lead to cognitive overload resulting in loss of information from short-term memory Knowledge society is intertwined with changing technology requiring new skills of its workforce. Cutler says that there is the perception that older workers lack experience with new technology and that retaining programs may be less effective and more expensive for older workers. Cascio says that there is a growth of virtual organizations. Saetre & Sornes say that it is a blurring of the traditional time and space boundaries has also led to many cases in the blurring of work and personal life Negative impacts of many scientific and technological innovations have on humans and the environment has led to some skepticism and resistance to increasing dependence on technology within the Knowledge Society. Doucet calls for city empowerment to have the courage and foresight to make decisions that are acceptable to its inhabitants rather that succumb to global consumer capitalism and the forces of international corporations on national and local governments Scientific and technological innovations that have transformed organizational life within a global economy have also supplanted human autonomy and control in work within a technologically oriented workplace The persuasive potential of technology raises the question of "how sensitive ... designers and programmers [should] be to the ethics of the persuasive technology they design." Technoethics can be used to determine the level of ethical responsibility that should be associated with outcomes of the use of technology, whether intended or unintended Rapidly changing organizational life and the history of unethical business practices have given rise to public debates concerning organizational responsibility and trust. The advent of virtual organizations and increase in remote work has bolstered ethical problems by providing more opportunities for fraud and the production of misinformation. Concerted efforts are required to uphold ethical values in advancing new knowledge and tools within societal relations which do not exclude people or limit liberties of some people at the expense of others Artificial Intelligence: Artificial Intelligence seems to be the one of the most talked of challenges when it comes ethics. In order to avoid these ethical challenges some solutions have been established; first and for most it should be developed for the common good and benefit of humanity. Secondly, it should operate on principles of intelligibility and fairness. It should also not be used to diminish the data rights or privacy of individuals, families, or communities. It is also believed that all citizens should have the right to be educated on artificial intelligence in order to be able to understand it. Finally, the autonomous power to hurt, destroy, or deceive humans should never be vested in artificial intelligence. Current issues Copyrights Digital copyrights are a complicated issue because there are multiple sides to the discussion. There are ethical considerations surrounding the artist, producer, and end user. Not to mention the relationships with other countries and the impact on the use of content housed in their countries. In Canada, national laws such as the Copyright Act and the history behind Bill C-32 are just the beginning of the government's attempt to shape the "wild west" of Canadian Internet activities. The ethical considerations behind Internet activities such a peer-to-peer file sharing involve every layer of the discussion – the consumer, artist, producer, music/movie/software industry, national government, and international relations. Overall, technoethics forces the "big picture" approach to all discussions on technology in society. Although time-consuming, this "big picture" approach offers some level of reassurance when considering that any law put in place could drastically alter the way we interact with our technology and thus the direction of work and innovation in the country. The use of copyrighted material to create new content is a hotly debated topic. The emergence of the musical "mashup" genre has compounded the issue of creative licensing. A moral conflict is created between those who believe that copyright protects any unauthorized use of content, and those who maintain that sampling and mash-ups are acceptable musical styles and, though they use portions of copyrighted material, the result is a new creative piece which is the property of the creator, and not of the original copyright holder. Whether or not the mashup genre should be allowed to use portions of copyrighted material to create new content is one which is currently under debate. Cybercriminality Cybercrime can consist of many subcategories and can be referred to as a big umbrella. Cyber theft such as online fraud, identity theft, and digital piracy can be classified as one sector. Another section of cybercrime can include cyber-violence which can be defined as online behavior that can be anywhere from hate speeches, harassment, cyberstalking, to behavior that leads to physical, psychological, or emotional assault against the well-being of an individual. Cyber obscenity is another section when child sexual exploitation materials are involved. Cyber trespass is when there is unauthorized computer system access. Cybercrime can encompass many other sections where technology and computers are used to assist and commit various forms of crimes. For many years , new technologies took an important place in social, cultural, political, and economic life. Thanks to the democratization of informatics access and the network's globalization, the number of exchanges and transaction is in perpetual progress. In the article, "The Dark Figure of Online Property Crime: Is Cyberspace Hiding a Crime Wave?", the authors analyze evidence that reveals cyber criminality rates are increasing as the typical street crimes gradually decrease. With the increase in cyber criminality, it is imperative to research more information on how to increase cyber security. The issue with increasing cyber security is that the more laws to protect people, the more citizens would feel threatened that their freedom is being compromised. One way to avoid making people feel threatened by all the security measures and protocols is by being as clear and straightforward as possible. Gregory Nojeim in his article "Cybersecurity and Freedom on the Internet" state, "Transparency in the cybersecurity program will build the confidence and trust that is essential to industry and public support for cybersecurity measures." It is important to create ethical laws that protect privacy, innovation, and consumers' freedom. Many people are exploiting the facilities and anonymity that modern technologies offer in order to commit multiple criminal activities. Cybercrime is one of the fastest growing areas of crime. The problem is that some laws that profess to protect people from those who would do wrong things via digital means also threaten to take away people's freedom. Privacy vs. security: Full-body airport scanners Since the introduction of full body X-ray scanners to airports in 2007, many concerns over traveler privacy have arisen. Individuals are asked to step inside a rectangular machine that takes an alternate wavelength image of the person's naked body for the purpose of detecting metal and non-metal objects being carried under the clothes of the traveler. This screening technology comes in two forms, millimeter wave technology (MM-wave technology) or backscatter X-rays (similar to x-rays used by dentists). Full-body scanners were introduced into airports to increase security and improve the quality of screening for objects such as weapons or explosives due to an increase of terrorist attacks involving airplanes occurring in the early 2000s. Ethical concerns of both travelers and academic groups include fear of humiliation due to the disclosure of anatomic or medical details, exposure to a low level of radiation (in the case of backscatter X-ray technology), violation of modesty and personal privacy, clarity of operating procedures, the use of this technology to discriminate against groups, and potential misuse of this technology for reasons other than detecting concealed objects. Also people with religious beliefs that require them to remain physically covered (arms, legs, face etc.) at all times will be unable and morally opposed to stepping inside of this virtually intrusive scanning technology. The Centre for Society, Science and Citizenship have discussed their ethical concerns including the ones mentioned above and suggest recommendations for the use of this technology in their report titled "Whole Body Imaging at airport checkpoints: the ethical and policy context" (2010). Privacy and GPS technologies The discourse around GPS tracking devices and geolocation technologies and this contemporary technology's ethical ramifications on privacy is growing as the technology becomes more prevalent in society. As discussed in the New York Timess Sunday Review on September 22, 2012, the editorial focused on the ethical ramifications that imprisoned a drug offender because of the GPS technology in his cellphone was able to locate the criminal's position. Now that most people carry on the person a cell, the authorities have the ability to constantly know the location of a large majority of citizens. The ethical discussion now can be framed from a legal perspective. As raised in the editorial, there are stark infractions that these geolocation devices on citizens' Fourth Amendment and their protection against unreasonable searches. This reach of this issue is not just limited to the United States but affects more democratic state that uphold similar citizens' rights and freedoms against unreasonable searches. These geolocation technologies are not only affecting how citizens interact with their state but also how employees interact with their workplaces. As discussed in article by the Canadian Broadcasting Company, "GPS and privacy", that a growing number of employers are installing geolocation technologies in "company vehicles, equipment and cellphones" (Hein, 2007). Both academia and unions are finding these new powers of employers to be indirect contradiction with civil liberties. This changing relationship between employee and employer because of the integration of GPS technology into popular society is demonstrating a larger ethical discussion on what are appropriate privacy levels. This discussion will only become more prevalent as the technology becomes more popular. Genetically modified organisms (GMOs) Genetically modified foods have become quite common in developed countries around the world, boasting greater yields, higher nutritional value, and greater resistance to pests, but there are still many ethical concerns regarding their use. Even commonplace genetically modified crops like corn raise questions of the ecological consequences of unintended cross pollination, potential horizontal gene transfer, and other unforeseen health concerns for humans and animals. Trademarked organisms like the "Glofish" are a relatively new occurrence. These zebrafish, genetically modified to appear in several fluorescent colours and sold as pets in the United States, could have unforeseen effects on freshwater environments were they ever to breed in the wild. Providing they receive approval from the U.S. Food and Drug Administration (FDA), another new type of fish may be arriving soon. The "AquAdvantage salmon", engineered to reach maturity within roughly 18 months (as opposed to three years in the wild), could help meet growing global demand. There are health and environmental concerns associated with the introduction any new GMO, but more importantly this scenario highlights the potential economic impact a new product may have. The FDA does perform an economic impact analysis to weigh, for example, the consequences these new genetically modified fish may have on the traditional salmon fishing industry against the long term gain of a cheaper, more plentiful source of salmon. These technoethical assessments, which regulatory organizations like the FDA are increasingly faced with worldwide, are vitally important in determining how GMOs—with all of their potential beneficial and harmful effects—will be handled moving forward. Pregnancy screening technology For over 40 years, newborn screening has been a triumph of the 20th century public health system. Through this technology, millions of parents are given the opportunity to screen for and test a number of disorders, sparing the death of their children or complications such as mental retardation. However, this technology is growing at a fast pace, disallowing researchers and practitioners from being able to fully understand how to treat diseases and provide families in need with the resources to cope. A version of pre-natal testing, called tandem mass spectrometry, is a procedure that "measures levels and patterns of numerous metabolites in a single drop of blood, which are then used to identify potential diseases. Using this same drop of blood, tandem mass spectrometry enables the detection of at least four times the number of disorders than was possible with previous technologies." This allows for a cost-effective and fast method of pre-natal testing. However, critics of tandem mass spectrometry and technologies like it are concerned about the adverse consequences of expanding newborn screen technology and the lack of appropriate research and infrastructure needed to provide optimum medical services to patients. Further concerns include "diagnostic odysseys", a situation in which the patient aimlessly continues to search for diagnoses where none exists. Among other consequences, this technology raises the issue of whether individuals other than newborn will benefit from newborn screening practices. A reconceptualization of the purpose of this screening will have far reaching economic, health and legal impact. This discussion is only just beginning and requires informed citizenry to reach legal if not moral consensus on how far we as a society are comfortable with taking this technology. Citizen journalism Citizen journalism is a concept describing citizens who wish to act as a professional journalist or media person by "collecting, reporting, analyzing, and disseminating news and information" According to Jay Rosen, citizen journalists are "the people formerly known as the audience," who "were on the receiving end of a media system that ran one way, in a broadcasting pattern, with high entry fees and a few firms competing to speak very loudly while the rest of the population listened in isolation from one another—and who today are not in a situation like that at all. ... The people formerly known as the audience are simply the public made realer, less fictional, more able, less predictable". The internet has provided society with a modern and accessible public space. Due to the openness of the internet, there are discernible effects on the traditional profession of journalism. Although the concept of citizen journalism is a seasoned one, "the presence of online citizen journalism content in the marketplace may add to the diversity of information that citizens have access to when making decisions related to the betterment of their community or their life". The emergence of online citizen journalism is fueled by the growing use of social media websites to share information about current events and issues locally, nationally and internationally. The open and instantaneous nature of the internet affects the criteria of information quality on the web. A journalistic code of ethics is not instilled for those who are practicing citizen journalism. Journalists, whether professional or citizen, have needed to adapt to new priorities of current audiences: accessibility, quantity of information, quick delivery and aesthetic appeal. Thus, technology has affected the ethical code of the profession of journalism with the popular free and instant sharing qualities of the internet. Professional journalists have had to adapt to these new practices to ensure that truthful and quality reporting is being distributed. The concept can be seen as a great advancement in how society communicates freely and openly or can be seen as contributing to the decay of traditional journalistic practices and codes of ethics. Other issues to consider: Privacy concerns: location services on cell devices which tell all users where a person is should they decide to turn on this feature, social media, online banking, new capabilities of cellular devices, Wi-fi, etc. New music technology: People see more electronic music today with the new technology able to create it, as well as more advanced recording technology Recent developments Despite the amassing body of scholarly work related to technoethics beginning in the 1970s, only recently has it become institutionalized and recognized as an important interdisciplinary research area and field of study. In 1998, the Epson Foundation founded the Instituto de Tecnoética in Spain under the direction of Josep Esquirol. This institute has actively promoted technoethical scholarship through awards, conferences, and publications. This helped encourage scholarly work for a largely European audience. The major driver for the emergence of technoethics can be attributed to the publication of major reference works available in English and circulated globally. The "Encyclopedia of Science, Technology, and Ethics" included a section on technoethics which helped bring it into mainstream philosophy. This helped to raise further interest leading to the publication of the first reference volume in the English language dedicated to the emerging field of Technoethics. The two volume Handbook of Research on Technoethics explores the complex connections between ethics and the rise of new technologies (e.g., life-preserving technologies, stem cell research, cloning technologies, new forms of surveillance and anonymity, computer networks, Internet advancement, etc.) This recent major collection provides the first comprehensive examination of technoethics and its various branches from over 50 scholars around the globe. The emergence of technoethics can be juxtaposed with a number of other innovative interdisciplinary areas of scholarship which have surfaced in recent years such as technoscience and technocriticism. Technology and ethics in the music industry With all the developments we've had in technology it has created a lot advancement for the music industry both positive and negative. A main concern is piracy and illegal downloading; with all that is available through the internet a lot of music (TV shows and movies as well) have become easily accessible to download and upload for free. This does create new challenges for artist, producers, and copyright laws. The advances it has positively made for the industry is a whole new genre of music. Computers are being used to create electronic music, as well as synthesizers (computerized/electronic piano). This type of music is becoming rapidly more common and listened to. These advances have allowed the industry to try new things and make new explorations. Because the internet is not controlled by a centralized power, users can maintain anonymity and find loopholes to avoid consequences for using peer-to-peer technology. The peer-to-peer network allows users to connect to a computer network and freely trade songs. Many companies, like Napster, have taken advantage of this because the protection of intellectual property is close to impossible on the internet. Digital and downloadable music has become a severe threat to major record companies. Associated digital music technologies have changed the power dynamics greatly for major record companies, music consumers, and the artists. Not only has this change in power dynamics provided more opportunities for independent music labels but also reduce costs for music. The digital environment in the music industry is always evolving. "The industry is beginning to work at adapting to the digital environment and downturns in a business performance like by online distribution and sales; harnessing visibility events for sales momentum; new capabilities for artist management in the digital age and by leveraging online communities to influence product development, among others". These new capabilities and new developments need strong intellectual property regulations to protect artists. Technology is a pillar in the music industry; therefore, it is imperative to have strong technology ethics. Copyright protections and legislation help artists trademark their music and protect their intellectual property. Protecting intellectual property in the music industry becomes tricky when music firms are in the process of incorporating new technologies and methodologies, which forces firms to be innovative and update the industry standards. Technology and ethics during the coronavirus pandemic As of April 20, 2020 there has been over 43 contract tracing apps available globally. Countries are in the process of creating their own methods of digitally tracing coronavirus status (symptoms, confirmed infected, exposed). Apple and Google are working together on a shared solution that helps with contract tracing around the world. Since this is a global pandemic with no end in sight, the restriction of some fundamental rights and freedoms may be ethically justifiable. It may be unethical to not use these tracing solutions to slow the spread. The European Convention on Human Rights, the United Nations International Covenant on Civil and Political Rights, and the United Nations Siracusa Principles all indicate when it is ethical to restrict the rights of the population to prevent the spread of infectious disease. All three documents cite that the circumstances for restricting rights must be time-bound, meet standards of necessity, proportionality, and scientific validity. We must evaluate if the gravity of the situation justifies the potential negative impact, if the evidence shows that the technology will work, is timely, will be adopted by enough people and yields accurate data and insights, and evaluate if the technology will only be temporary. These three documents also provide guidelines on how to ethically develop and design technologies. The development and design guidelines are important for being effective and for security reasons. The development of technology has enhanced the ability to obtain, track, and share data. Technology has been mobilized by governments around the world to combat the issue of COVID-19, which has brought attention to several issues surrounding ethics. Governments have implemented technologies such as smartphone metadata and Bluetooth applications to contact trace and notify the public of any important information. There are implications for privacy as technologies such as metadata have the capacity to track every movement of an individual. Due to the Coronavirus Pandemic, contact tracing and other tracking apps have been implemented globally in order to fight against the pandemic. Countries across the globe have developing various methods of digitally tracing corona virus such as outbreak origin, symptoms, confirmed positives, and those who are potentially exposed. Governments around the world combined available technology to identify individuals and surveillance technology while still having a low impact on individuals privacy. In 2020, the Australian government released a Bluetooth connected app that allows phones communicate through Bluetooth opposed to metadata. This allowed the app to connect with surrounding phones through Bluetooth opposed to metadata or GPS, which can have a bigger impact on individual privacy. The technology records individuals who have been in close proximity, by connecting through their phones, and recording the data for a certain time period before deleting itself. The app does not track individual's locations but still can pinpoint if they have had close contact with those who were positive or exposed. On the other hand, some countries such as South Korea utilized metadata technology to closely surveillance their citizens. Metadata can provide a detailed description of an individual's movements by staying regularly in contact with the local cellular towers to maintain reception. In S. Korea, the government utilized individuals' metadata information to convey any public health message to the public. Anonymized information would be released to the public of the locations of individuals who have tested positive for COVID-19. Similarly in Israel, the government approved emergency regulations that allowed authorities to utilize a database that tracks the movements of individuals that have tested positive for COVID-19. The rise of surveillance technologies by the government to track individuals raises many questions of ethic concerns. As lockdowns and Covid protocols continue, the focus on protecting public health can severely conflict with individual autonomy, although it can be necessary to implement certain technologies and protocols. Even though these three bodies of government can deem contact tracing ethical, all these contact tracing apps come with a price. They are collecting sensitive personal data including health data. This poses a threat to violate HIPAA and PII if not handled and processed correctly. Even if these apps are only used temporarily, they are storing permanent records of health, movements, and social interactions. Not only do we have to consider the ethical implications of your personal information being stored, but we must also look at the accessibility and digital literacy of the users. Not everyone has access to a smartphone or a cell phone. If we are developing smartphone applications, we will be missing a huge portion of coronavirus data. While it may be necessary to utilize technology to slow the spread of coronavirus, the Government needs to design and deploy the technology in a way that does not breach the public trust. There is a fine line of saving lives and possibly harming the fundamental rights and freedoms of individuals. Future developments The future of technoethics is a promising, yet evolving field. The studies of e-technology in workplace environments are an evolving trend in technoethics. With the constant evolution of technology, and innovations coming out daily, technoethics is looking to be a rather promising guiding framework for the ethical assessments of new technologies. Some of the questions regarding technoethics and the workplace environment that have yet to be examined and treated are listed below: Are organizational counter measures not necessary because it invades employee privacy? Are surveillance cameras and computer monitoring devices invasive methods that can have ethical repercussions? Should organizations have the right and power to impose consequences? Artificial intelligence Artificial intelligence is a large range of technology that deals with building smart machines and data processing so tasks can be performed by machines that are normally completed by humans. AI may prove to be beneficial to human life, but it can also quickly become pervasive and dangerous. Changes in AI are difficult to anticipate and understand, such as employers spying on workers, facial recognition, deep fakes, etc. Along with AI, the algorithms used to implement the technology may prove to be biased which can have detrimental effects on individuals. For example, in facial recognition technology, the AI may be proven to be biased toward different ethnic and racial groups than others. These challenges have social, racial, ethical, and economic implications. Deepfakes Deepfake is a form of media in which one existing image or video is replaced or altered by someone else. Altering may include acting out fake content, false advertisement, hoaxes, and financial fraud. The technology of deepfakes may also use machine learning or artificial intelligence. Deepfakes propose an ethical dilemma due to how accessible they are as well as the implications on one's integrity it may cause to viewers. Deepfakes reconsider the challenge of trustworthiness of the visual experience and can create negative consequences. Deepfakes contribute to the problem of "fake news" by enabling both the more widespread fabrication or manipulation of media that may be deliberately used for the purposes of disinformation. There are four categories of deepfakes: deepfake porn, deepfake political campaigns, deepfake for commercial use, and creative deepfakes. Deepfakes have many harmful effects such as deception, intimidation, and reputational harm. Deception causes views to synthesize a form of reality that did not exist before and may think of it as real footage. The contents of the footage may be detrimental depending on what it is. Detrimental information may include fraudulent voter information, candidate information, money fraud, etc. Intimidation may occur by targeting a certain audience with harmful threats to generate fear. An example of intimidation may be deepfake revenge pornography which also ties into reputational harm. Accessibility of deepfakes also raises ethical dilemmas as it can be accessed through apps like FakeApp, Zao, and Impressions. The accessibility to these applications may cause legal action. In 2018 the Malicious Deep Fake Prohibition Act was introduced to protect those who may be harmed by deepfakes. These crimes can result in prosecution for harassment or sentences to imprisonment. Although there can be legal actions for deepfakes, they do become increasingly difficult as many parties are involved in its development. The many parties for a deepfake such as the software developer, the application for amplification, the user of the software, etc. Due to these many different components, it may be difficult to prosecute individuals for deepfakes. United Nations Educational, Scientific and Cultural Organization (UNESCO) UNESCO – a specialized intergovernmental agency of the United Nations, focusing on promotion of education, culture social and natural sciences and communication and information. In the future, the use of principles as expressed in the UNESCO Universal Declaration on Bioethics and Human Rights (2005) will also be analyzed to broaden the description of bioethical reasoning (Adell & Luppicini, 2009). User data In a digital world, much of users' personal lives are stored on devices such as computers and smartphones, and we trust the companies we store our lives on to take care of our data. A topic of discussion regarding the ethics of technology is just exactly how much data these companies really need and what they are doing with it. Another major cause for concern is the security of our personal data and privacy, whether it is leaked intentionally or not. User data has been one of the main topics regarding ethics as companies and government entities increasingly have access to billions of users' information. Why do companies need so much data regarding their users and are users aware that their data is being tacked? These questions have risen over the years over concerns of how much do companies actually know. Some websites and apps now ask users if they are allowed to track user activity across different apps with the option to decline. Most companies before did not ask or notify users that their app activity would be tracked. Companies over the years have been facing an increased number of data hacks where user's data such as credit cards, social security, phone numbers, and addresses have been leaked. Users of social networks such as Snapchat and Facebook have been facing phone calls from scammers as recent data hacks released users' phone numbers. The most recent breach to affect Facebook leaked over 533 million Facebook users from 106 countries, including 32 million users alone in the U.S. The type of information leaked included user phone numbers, Facebook IDs, full names, locations, birthdates, bios, and email addresses. Hackers and web scrapers have been selling Facebook user data on hacker forums, information for 1 million users can go for $5,000 on these forums. Large companies share their users' data constantly. In 2018, the U.S, government cracked down on Facebook selling user data to other companies after declaring that it had made the data in question inaccessible. One such case was in a scandal regarding Cambridge Analytica, in which Facebook sold user data to the company without consent from the users whose data was being accessed. The data was then used for several political agendas, such as the Brexit vote and the U.S. Presidential Election of 2016. In an interview with CBS' 60 Minutes, Trump campaign manager Brad Parscale described in detail how he used data taken from different social media websites to create ads that were both visually appealing to potential voters and targeted the issues that they felt strongest about. Besides swinging political races, the theft of people's data can result in serious consequences on an individual level. In some cases, hackers can breach websites or businesses that have identifying information about a person, such as their credit card number, cell phone number, and address, and upload it to the dark web for sale, if they decide not to use it for their own deviant purposes. Drones In the book Society and Technological Change, 8th Edition, by Rudi Volti, the author comments on unmanned aerial vehicles, also known as UAVs or drones. Once used primarily as military technology, these are becoming increasingly accessible tools to the common person for hobbies like photography. In the author's belief, this can also cause concern for security and privacy, as these tools allow people with malicious intents easier access to spying. Outside of public areas, drones are also able to be used for spying on people in private settings, even in their own homes. In an article by today.com, the author writes about people using drones and taking videos and photographs of people in their most private moments, even in the privacy of their own home. From an ethical perspective, drones have a multitude of ethical issues many of which are determining current legal policy. Some areas include the ethical military usage of drones, private non-military use by hobbyists for photography or potential spying, drone usage in political campaigns as a way to spread campaign messages, drone usage in the private business sector as a means for delivery, and ethical usage of public/private airspace. Pet Cloning In 2020 pet cloning is to become something of interest for those who can afford it. For $25k - $50k anyone will be able to clone their house pet but there is no guarantee you will get the exact same pet that you once had. This may seem very appealing to certain animal-lovers, but what about all of those animals that already have no home? There are a few different ethical questions here; the first being how is this fair to the animals that are suffering out in the wilderness with no home? The second being that cloning animals is not only for pets, but for all animals in general. Maybe people are concerned that people are going to clone animals for food purposes.Another question about animal cloning is it is good for the welfare of the animal or will the radiation and other procedural aspects cause the animals life to end earlier? These are just some of many concerns some people have with animal cloning. Animal cloning The ethical standpoint of animal cloning is a heavily debated topic in a plethora of different career paths. Some of these ethical concerns are the health and well being of the animals, long term side effects, obstetrical complications that occur during cloning, environmental impacts, use of clones in farming/repopulation of endangered species, and the use of clones for other research, specifically in the medical/pharmaceutical field. Many of these concerns are only more recently spoken about due to the advancement of cloning technology in the past decade since humanity's first clone was only twenty-five years ago in 1996 resulting in the birth of a sheep known as Dolly. Facebook and Meta's ethical concerns Facebook, or rather Meta Platforms, Facebook's parent company is currently one of the top social networking sites, throughout the early to late 2010s and into current times (2022). A variety of issues ranging from privacy concerns, the issue of who bears the responsibility of unhealthy social interactions and other unhealthy behaviors, to deliberate enabling of misinformation on the platform. Recent issues such as Facebook data leaks and circulation of fake news highlights the downside of social media when in the wrong hands. following are a few examples of various ethical concerns raised throughout the years in relation to Facebook. Federal Trade Commission v. Facebook A recent Forbes interview conducted on October 22, 2021, by Curt Steinhorst, a contributor for Forbes, with Michael Thate, an ethics teacher employed at Princeton University, asserts that in addition to the Federal Trade Commission v. Facebook ruling determining that Facebook had engaged in unethical antitrust behaviors with the acquisition of its competing social media platforms Instagram and WhatsApp, "Facebook developed an algorithm to capture user attention and information into a platform that they knew promoted unhealthy behaviors." Firstly the unethical acquisition of smaller competing social media platforms restricts free-market practices and restricts users' choices in, at least in this case, what social media sites they choose to access. In addition to the antitrust, the promotion of unhealthy behaviors and lifestyles to increase user engagement on the platform is considered to be by Michael Thate to be an ethical concern, as users of the social media platform are given a choice between maintaining a healthy lifestyle and engaging in the social media platform that is designed to keep them on the site and actively engaged regardless of its impact on the wellbeing of the user. Facebook's algorithm On October 4, 2021, CBS News interviewed Frances Haugen, a whistleblower and former employee of Facebook, who revealed Facebook was aware of various concerning ethical practices. "The complaints say Facebook's own research shows that it amplifies hate, misinformation, and political unrest—but the company hides what it knows. One complaint alleges that Facebook's Instagram harms teenage girls." These various unethical practices were all employed to, yet again promote increased user engagement with the social media platform. Fences Haugen stated in the interview: "The thing I saw at Facebook over and over again was there were conflicts of interest between what was good for the public and what was good for Facebook. And Facebook, over and over again, chose to optimize for its own interests, like making more money." An article written on February 10, 2021, by Paige Cooper outlines how Facebook's algorithm has changed over the years highlights the changes made by Facebook to prioritize the more emotional interactions on the site. Facebook–Cambridge Analytica Through the 2010s the British political consulting firm Cambridge Analytica in a conjoined effort with Facebook gathered information and personal data on upwards of 87 million nonconsenting users as stated by a New York Times article titled "Cambridge Analytica and Facebook: The Scandal and the Fallout So Far". The illegally obtained data was then utilized in Donald Trump's 2016 presidential campaign to help develop personalized ads and campaign messages based on the data provided by Cambridge Analytica. An article was written by The Guardian on March 18, 2021, interviewing a Cambridge Analytica whistleblower Christopher Wylie. In the interview, Wylie asserted that the data given to him was legally obtained and that he and various other academic analyses were also unaware of the nature to which the data used in the psychological profiles was obtained. Areas of technoethical inquiry Biotech ethics Biotech ethics concerned with ethical dilemmas surrounding the use of biotechnologies in fields including medical research, health care, and industrial applications. Topics such as cloning ethics, e-health ethics, telemedicine ethics, genetics ethics, neuroethics, and sport and nutrition ethics fall into this category; examples of specific issues include the debates surrounding euthanasia and reproductive rights. Telemedicine is a medical technology that has been used to advance clinical care with the use of video conferencing, text messaging, and applications. With the advantage of telemedicine, there are concerns about its pitfalls such as threats to patient privacy and HIPAA regulations. Cyberattacks in healthcare are a significant concern when implementing technology because there needs to be measures in place to keep patient privacy secure. One type of cyber attack is a medical device hijack also known as medjack where hackers can alter the functionality of implants, and expose patient medical history. When implementing technology, it is important to check for weaknesses that can cause vulnerability to hacking. The use of technology in ethics also becomes a key factor when considering artificial intelligence. AI is not seen as a neutral tool, and policies have been set in place to ensure it is not misused under human bias. Although AI is a valuable tool in medicine, the current ethical policies are not up to standard to accommodate AI as it is a multi-disciplinary approach. AI in healthcare is not available to make clinical decisions; however, it can provide assistance in surgeries, imaging, etc. Technoethics and cognition This area of technoethical inquiry is concerned with technology's relation to the human mind, artificial agents, and society. Topics of study that would fit into this category would be artificial morality and moral agents, moral outsourcing, technoethical systems and techno-addiction. An artificial agent describes any type of technology that is created to act as an agent, either of its own power or on behalf of another agent. An artificial agent may try to advance its own goals or those of another agent. Mass surveillance The ethics behind mass surveillance has become a highly discussed ethical topic in the twenty-first century, especially in the United States due to the tragedy of 9/11. Some areas of ethical concern involve privacy, discrimination, trust in government, infringement of government-granted rights/basic human rights, conflict of interest, stigmatization, and obtrusiveness. Many of these ethical topics in the timeframe between 2001 and 2021 have become the main topic of discussion in many recent laws all throughout the world. Shortly after 9/11 when the United States began to fear the idea that more terrorist attacks could occur on American soil. A law passed on October 26, 2001, known as the Patriot Act was one of the first larger Mass Surveillance laws passed in the United States. Years later Europe would begin to follow suit with their own set of mass surveillance laws after a string of terrorist attacks. After the 2015 terrorist attacks in France, the French government would move forward with passing the International Electronic Communications Law. The IEC would recognize the power of the French Directorate-General for External Security allowing them to collect, monitor, and intercept all communications sent or received on French territory. In 2016, the United Kingdom would pass the Investigatory Powers Act of 2016, a law allowing the GCHQ to engage in acquisition, interception, and equipment interference of communications/systems sent by anyone on British territory. Finally, in 2016, another law like the Investigatory Powers Act was passed in Germany that was named the Communications Intelligence Gathering Act. This act allowed the German intelligence community to gather foreign nationals communications while they were in German territory. In 2021, Australia passed a law known as the Surveillance Legislation Amendment, which granted the Australian Federal Police and Australian Criminal Intelligence Commission the right to modify or delete data of suspected offenders, Collect intelligence on criminal networks, and finally, forcefully break into a suspected offender's online account. After these laws were passed all throughout Europe, and later on in Australia, a string of protests would begin to arise involving the laws, as citizens from each country would feel it infringed their privacy rights. Two years after the Investigatory Powers Act of 2016 was passed in the United Kingdom the English High Court would rule that the act would have to be rewritten. This ruling occurred due to the High Court finding the law to be incompatible with EU law since the law "authorizes the UK government to issue retention notices with no prior independent checks, such as review by a court or other body, and for the purpose of investigating crime that is not "serious crime"; and (2) subsequent access to any retained data was similarly not subject to any independent authorization and not limited to the purpose of combating "serious crime". The origin of this ruling comes from a human rights group known as Liberty who first began to battle the act shortly after it was enacted as they stated it violates the United Kingdom's citizens the right to privacy. In 2020, Four years after Germany enacted the Communications Intelligence Gathering Act it would also make its way to court to be reviewed. Receiving heavy backlash from multiple members of the German public and Non-German citizens. Many of these complaints continued to dwell on the same issue of the privacy of both German and non-German citizens. After a two day trial, the high German court did rule that the law was unconstitutional and gave the German parliament until 2021 to make corrections to the Act. Though, as of recent in the year 2020 during the height of the COVID-19 Pandemic. The ethical atmosphere regarding public health surveillance began to take center stage due to its overall use during the height of the pandemic. The purpose of this mass surveillance was for data collection of the transmission of the COVID-19. Though, many individuals around the world cited they felt this form of surveillance infringed on their privacy and basic human rights. Another concern regarding this level of surveillance was the lack of government or institutional policy documents regarding how to address the ethical challenges around mass surveillance to track a pandemic transmission rate. The use of this mass surveillance was used on a far larger scale compared to some of the other acts passed in recent years, as this had a more global focus due to the want to bring the transmission of COVID-19 to a halt. For example, on March 16, 2020, the Israeli government allowed emergency regulations regarding mass location tracking of citizens to slow the spread of the disease. Singapore and Taiwan also did something similar, yet their method of mass surveillance was allowing their law-enforcement agencies to monitor quarantine orders. Technoethics and society This field is concerned with the uses of technology to ethically regulate aspects of a society. For example: digital property ethics, social theory, law, science, organizational ethics and global ethics. Digital property rights or DPR refers to individual rights on information available online such as email accounts, online website accounts, posts, blogs, pictures, and other digital media. Digital property rights can be regulated and protected by making the digital property tamper-proof, by adding legal clause to the digital properties, and limiting the sharing of software code. Social theory refers to how societies change and develop over time in terms of behavior and explanation of behaviors. Technology has a great impact on social change. As technology evolves and upgrades, human interaction goes along with the changes. "Technological theory suggests that technology is an important factor for social change, and it would initiate changes in the arrangement of social relationships". Organizational ethics refers to the code of conduct and the way an organization responds to stimulus. Techno ethics plays a role in organizational ethics because technology can be embedded and incorporated in many different aspects of ethical values. Technofeminism Technoethics has concerned itself with society as a general group and made no distinctions between the genders, but considers technological effects and influences on each gender individually. This is an important consideration as some technologies are created for use by a specific gender, including birth control, abortion, fertility treatments, and Viagra. Feminists have had a significant influence on the prominence and development of reproductive technologies. Technoethical inquiry must examine these technologies' effects on the intended gender while also considering their influence on the other gender. Another dimension of technofeminism concerns female involvement in technological development: women's participation in the field of technology has broadened society's understanding of how technology affects the female experience in society. Information and communication technoethics Information and communication technoethics is "concerned with ethical issues and responsibilities arising when dealing with information and communication technology in the realm of communication." This field is related to internet ethics, rational and ethical decision making models, and information ethics. A major area of interest is the convergence of technologies: as technologies become more interdependent and provide people with multiple ways of accessing the same information, they transform society and create new ethical dilemmas. This is particularly evident in the realms of the internet. In recent years, users have had the unprecedented position of power in creating and disseminating news and other information globally via social networking; the concept of "citizen journalism" primarily relates to this. With developments in the media, has led to open media ethics as Ward writes, leading to citizen journalism. In cases such as the 2004 Indian Ocean Tsunami or the 2011 Arab Spring movements, citizen journalists were seen to have been significant sources of facts and information in relation to the events. These were re-broadcast by news outlets, and more importantly, re-circulated by and to other internet users. As Jay David Bolter and Richard Grusin state in their book Remediation: Understanding New Media (1999): "The liveness of the Web is a refashioned version of the liveness of broadcast television" However, it is commonly political events (such as 'Occupy' movements or the Iran Elections of 2009) that tend to raise ethical questions and concerns. In the latter example, there had been efforts made by the Iranian government in censoring and prohibiting the spread of internal happenings to the outside by its citizen journalists. This occurrence questioned the importance of the spread of crucial information regarding the issue, and the source from which it came from (citizen journalists, government authorities, etc.). This goes to prove how the internet "enables new forms of human action and expression [but] at the same time it disables [it]" Information and Communication Technoethics also identifies ways to develop ethical frameworks of research structures in order to capture the essence of new technologies. Educational and professional technoethics Technoethical inquiry in the field of education examines how technology impacts the roles and values of education in society. This field considers changes in student values and behavior related to technology, including access to inappropriate material in schools, online plagiarism using material copied directly from the internet, or purchasing papers from online resources and passing them off as the student's own work. Educational technoethics also examines the digital divide that exists between educational institutions in developed and developing countries or between unequally-funded institutions within the same country: for instance, some schools offer students access to online material, while others do not. Professional technoethics focuses on the issue of ethical responsibility for those who work with technology within a professional setting, including engineers, medical professionals, and so on. Efforts have been made to delineate ethical principles in professions such as computer programming (see programming ethics). Environmental and engineering technoethics Environmental technoethics originate from the 1960s and 1970s' interest in environment and nature. The field focuses on the human use of technologies that may impact the environment; areas of concern include transport, mining, and sanitation. Engineering technoethics emerged in the late 19th century. As the Industrial Revolution triggered a demand for expertise in engineering and a need to improve engineering standards, societies began to develop codes of professional ethics and associations to enforce these codes. Ethical inquiry into engineering examines the "responsibilities of engineers combining insights from both philosophy and the social sciences." Technoethical assessment and design A technoethical assessment (TEA) is an interdisciplinary, systems-based approach to assessing ethical dilemmas related to technology. TEAs aim to guide actions related to technology in an ethical direction by advancing knowledge of technologies and their effects; successful TEAs thus produce a shared understanding of knowledge, values, priorities, and other ethical aspects associated with technology. TEAs involve five key steps: Evaluate the intended ends and possible side effects of the technology in order to discern its overall value (interest). Compare the means and intended ends in terms of technical and non-technical (moral and social) aspects. Reject those actions where the output (overall value) does not balance the input in terms of efficiency and fairness. Consider perspectives from all stakeholder groups. Examine technological relations at a variety of levels (e.g. biological, physical, psychological, social, and environmental). Technoethical design (TED) refers to the process of designing technologies in an ethical manner, involving stakeholders in participatory design efforts, revealing hidden or tacit technological relations, and investigating what technologies make possible and how people will use them. TED involves the following four steps: Ensure that the components and relations within the technological system are explicitly understood by those in the design context. Perform a TEA to identify relevant technical knowledge. Optimize the technological system in order to meet stakeholders' and affected individuals' needs and interests. Consult with representatives of stakeholder and affected groups in order to establish consensus on key design issues. Both TEA and TED rely on systems theory, a perspective that conceptualizes society in terms of events and occurrences resulting from investigating system operations. Systems theory assumes that complex ideas can be studied as systems with common designs and properties which can be further explained using systems methodology. The field of technoethics regards technologies as self-producing systems that draw upon external resources and maintain themselves through knowledge creation; these systems, of which humans are a part, are constantly in flux as relations between technology, nature, and society change. TEA attempts to elicit the knowledge, goals, inputs, and outputs that comprise technological systems. Similarly, TED enables designers to recognize technology's complexity and power, to include facts and values in their designs, and to contextualize technology in terms of what it makes possible and what makes it possible. Organizational technoethics Recent advances in technology and their ability to transmit vast amounts of information in a short amount of time has changed the way information is being shared amongst co-workers and managers throughout organizations across the globe. Starting in the 1980s with information and communications technologies (ICTs), organizations have seen an increase in the amount of technology that they rely on to communicate within and outside of the workplace. However, these implementations of technology in the workplace create various ethical concerns and in turn a need for further analysis of technology in organizations. As a result of this growing trend, a subsection of technoethics known as organizational technoethics has emerged to address these issues. Key scholarly contributions Key scholarly contributions linking ethics, technology, and society can be found in a number of seminal works: The Imperative of Responsibility: In Search of Ethics for the Technological Age (Hans Jonas, 1979). On Technology, Medicine and Ethics (Hans Jonas, 1985). The Real World of Technology (Franklin, 1990). Thinking Ethics in Technology: Hennebach Lectures and Papers, 1995-1996 (Mitcham, 1997). Technology and the Good Life (Higgs, Light & Strong, 2000). Readings in the Philosophy of Technology (Kaplan, 2004). Ethics and technology: Ethical issues in an age of information and communication technology (Tavani, 2004). This resulting scholarly attention to ethical issues arising from technological transformations of work and life has helped given rise to a number of key areas (or branches) of technoethical inquiry under various research programs (i.e., computer ethics, engineering ethics, environmental technoethics, biotech ethics, nanoethics, educational technoethics, information and communication ethics, media ethics, and Internet ethics).

Holistic management (agriculture)

Holistic Management (from holos, a Greek word meaning all, whole, entire, total) in agriculture is an approach to managing resources that was originally developed by Allan Savory for grazing management., Holistic Management has been likened to "a permaculture approach to rangeland management". Holistic Management is a registered trademark of Holistic Management International (no longer associated with Allan Savory). It has faced criticism from many researchers who argue it is unable to provide the benefits claimed. Definition Holistic management describes a systems thinking approach to managing resources. Originally developed by Allan Savory, it is now being adapted for use in managing other systems with complex social, ecological and economic factors. Holistic planned grazing is similar to rotational grazing but differs in that it more explicitly recognizes and provides a framework for adapting to the four basic ecosystem processes: the water cycle, the mineral cycle including the carbon cycle, energy flow, and community dynamics (the relationship between organisms in an ecosystem), giving equal importance to livestock production and social welfare. Holistic Management has been likened to "a permaculture approach to rangeland management". Framework The Holistic Management decision-making framework uses six key steps to guide the management of resources: Define in its entirety what you are managing. No area should be treated as a single-product system. By defining the whole, people are better able to manage. This includes identifying the available resources, including money, that the manager has at his disposal. Define what you want now and for the future. Set the objectives, goals and actions needed to produce the quality of life sought, and what the life-nurturing environment must be like to sustain that quality of life far into the future. Watch for the earliest indicators of ecosystem health. Identify the ecosystem services that have deep impacts for people in both urban and rural environments, and find a way to easily monitor them. One of the best examples of an early indicator of a poorly functioning environment is patches of bare ground. An indicator of a better functioning environment is newly sprouting diversity of plants and a return or increase of wildlife. Don't limit the management tools you use. The eight tools for managing natural resources are money/labor, human creativity, grazing, animal impact, fire, rest, living organisms and science/technology. To be successful you need to use all these tools to the best of your ability. Test your decisions with questions that are designed to help ensure all your decisions are socially, environmentally and financially sound for both the short and long term. Monitor proactively, before your managed system becomes more imbalanced. This way the manager can take adaptive corrective action quickly, before the ecosystem services are lost. Always assume your plan is less than perfect and use a feedback loop that includes monitoring for the earliest signs of failure, adjusting and re-planning as needed. In other words use a "canary in a coal mine" approach. Four principles Savory stated four key principles of Holistic Management planned grazing, which he intended to take advantage of the symbiotic relationship between large herds of grazing animals and the grasslands that support them: Nature functions as a holistic community with a mutualistic relationship between people, animals and the land. If you remove or change the behavior of any keystone species like the large grazing herds, you have an unexpected and wide-ranging negative impact on other areas of the environment. It is absolutely crucial that any agricultural planning system must be flexible enough to adapt to nature’s complexity, since all environments are different and have constantly changing local conditions. Animal husbandry using domestic species can be used as a substitute for lost keystone species. Thus when managed properly in a way that mimics nature, agriculture can heal the land and even benefit wildlife, while at the same time benefiting people. Time and timing is the most important factor when planning land use. Not only is it crucial to understand how long to use the land for agriculture and how long to rest, it is equally important to understand exactly when and where the land is ready for that use and rest. Development The idea of holistic planned grazing was developed in the 1960s by Allan Savory, a wildlife biologist in his native Southern Rhodesia. Setting out to understand desertification in the context of the larger environmental movement, and influenced by the work of André Voisin, he hypothesized that the spread of deserts, the loss of wildlife, and the resulting human impoverishment were related to the reduction of the natural herds of large grazing animals and, even more, the changed behavior of the few remaining herds. Savory hypothesized further that livestock could be substituted for natural herds to provide important ecosystem services like nutrient cycling. However, while livestock managers had found that rotational grazing systems can work for livestock management purposes, scientific experiments demonstrated it does not necessarily improve ecological issues such as desertification. As Savory saw it, a more comprehensive framework for the management of grassland systems — an adaptive, holistic management plan — was needed. For that reason Holistic Management has been used as a Whole Farm/Ranch Planning tool In 1984, he founded the Center for Holistic Resource Management which became Holistic Management International. In many regions, pastoralism and communal land use are blamed for environmental degradation caused by overgrazing. After years of research and experience, Savory came to understand this assertion was often wrong, and that sometimes removing animals actually made matters worse. This concept is a variation of the trophic cascade, where humans are seen as the top level predator and the cascade follows from there. Savory developed a management system that he claimed would improve grazing systems. Holistic planned grazing is one of a number of newer grazing management systems that aim to more closely simulate the behavior of natural herds of wildlife and has been claimed to improve riparian habitats and water quality over systems that often led to land degradation, and claimed to improve range condition for both livestock and wildlife. Savory claims that Holistic Planned Grazing holds potential in mitigating climate change, while building soil, increasing biodiversity, and reversing desertification. This practice uses fencing and/or herders to restore grasslands. Carefully planned movements of large herds of livestock mimic the processes of nature where grazing animals are kept concentrated by pack predators and forced to move on after eating, trampling, and manuring an area, returning only after it has fully recovered. This grazing method seeks to emulate what occurred during the past 40 million years as the expansion of grass-grazer ecosystems built deep, rich grassland soils, sequestering carbon, and consequently cooling the planet. Uses While originally developed as a tool for range land use and restoring desertified land, the Holistic Management system can be applied to other areas with multiple complex socioeconomic and environmental factors. One such example is integrated water resources management, which promotes sector integration in development and management of water resources to ensure that water is allocated fairly between different users, maximizing economic and social welfare without compromising the sustainability of vital ecosystems.Another example is mine reclamation. A fourth use of Holistic Management® is in certain forms of no till crop production, intercropping, and permaculture. Holistic Management has been acknowledged by the United States Department of Agriculture. The most comprehensive use of Holistic Management is as a Whole Farm/Ranch Planning tool which has been used successfully by farmers and ranchers. For that reason, the USDA invested six years of Beginning Farmer/Rancher Development funding to use it to train beginning women farmers and ranchers. Criticism There are many peer-reviewed studies and journalistic publications that dispute the claims of Holistic Management theory. A 2014 review examined five specific ecological assumptions of Holistic Management and found that none were supported by scientific evidence in the Western US. A paper by Richard Teague et al. claims that the different criticisms had examined rotational systems in general and not holistic planned grazing. A meta-analysis of relevant studies between 1972 and 2016 found that Holistic Planned Grazing had no better effect than continuous grazing on plant cover, plant biomass and animal production, although it may have benefited some areas with higher precipitation. Conversely, at least three studies have documented soil improvement as measured by soil carbon, soil nitrogen, soil biota, water retention, nutrient-holding capacity, and ground litter on grazed land using multi-pasture grazing methods compared to continuously grazed land. There is also evidence that multi-pasture grazing methods may increase water retention compared to non-grazed land. However, George Wuerthner, writing in The Wildlife News in a 2013 article titled, "Allan Savory: Myth And Reality" stated, "The few scientific experiments that Savory supporters cite as vindication of his methods (out of hundreds that refute his assertions), often fail to actually test his theories. Several of the studies cited on HM web site had utilization levels (degree of vegetation removed) well below the level that Savory actually recommends." These critiques have been challenged on the grounds that many studies examined rotational grazing systems in general and not Holistic Management or Holistic Planned Grazing. In addition to a grazing method, Holistic Management involves goal setting, experiential learning and an emphasis on monitoring and adaptive decision-making that have not been captured by many scientific field trials. This has been proposed as a reason why many land managers have reported a more positive experience of Holistic Management than scientific studies. However, a 2022 review of 22 “farm-scale” studies, many of which included adaptive management, again found that Holistic Management had no effect on or reduced plant or animal productivity. The same study found that Holistic Management was associated with improved social cohesion and peer-to-peer learning, but concluded that the “social cohesion, learning and networking so prevalent on HM farms could be adopted by any farming community without accepting the unfounded HM rhetoric”. Carbon sequestration claims Savory has also faced criticisms for claiming the carbon sequestration potential of holistic grazing is immune from empirical scientific study. For instance, in 2000, Savory said that "the scientific method never discovers anything" and “the scientific method protects us from cranks like me". A 2017 factsheet authored by Savory stated that “Every study of holistic planned grazing that has been done has provided results that are rejected by range scientists because there was no replication!". TABLE Debates sums this up by saying "Savory argues that standardisation, replication, and therefore experimental testing of HPG [Holistic Planned Grazing] as a whole (rather than just the grazing system associated with it) is not possible, and that therefore, it is incapable of study by experimental science", but "he does not explain how HPG can make causal knowledge claims with regards to combating desertification and climate mitigation, without recourse to science demonstrating such connections." There is a less developed evidence base comparing Holistic management with the absence of livestock on grasslands. Several peer-reviewed studies have found that excluding livestock completely from semi-arid grasslands can lead to significant recovery of vegetation and soil carbon sequestration. A 2021 peer-reviewed paper found that sparsely grazed and natural grasslands account for 80% of the total cumulative carbon sink of the world’s grasslands, whereas managed grasslands (i.e. with greater livestock density) have been a net greenhouse gas source over the past decade. A 2011 study found that multi-paddock grazing of the type endorsed by Savory resulted in more soil carbon sequestration than heavy continuous grazing, but very slightly less soil carbon sequestration than "graze exclosure" (excluding grazing livestock from land). Another peer-reviewed paper found that if current pastureland was restored to its former state as wild grasslands, shrublands, and sparse savannas without livestock this could store an estimated 15.2 - 59.9 Gt additional carbon. In 2013 the Savory Institute published a response to some of their critics. The same month Savory was a guest speaker with TED and gave a presentation titled "How to Fight Desertification and Reverse Climate Change". In his TED Talk, Savory has claimed that holistic grazing could reduce carbon dioxide levels to pre-industrial levels in a span of 40 years, solving the problems caused by climate change. Commenting on his TED talk, Savory has since denied claiming that holistic grazing can reverse climate change, saying that “I have only used the words address climate change… although I have written and talked about reversing man-made desertification”. RealClimate.org published a piece saying that Savory's claims that his technique can bring atmospheric carbon "back to pre-industrial levels" are "simply not reasonable." According to Skeptical Science, "it is not possible to increase productivity, increase numbers of cattle and store carbon using any grazing strategy, never-mind Holistic Management [...] Long term studies on the effect of grazing on soil carbon storage have been done before, and the results are not promising.[...] Because of the complex nature of carbon storage in soils, increasing global temperature, risk of desertification and methane emissions from livestock, it is unlikely that Holistic Management, or any management technique, can reverse climate change. According to a 2016 study published by the University of Uppsala, the actual rate at which improved grazing management could contribute to carbon sequestration is seven times lower than the claims made by Savory. The study concludes that Holistic Management cannot reverse climate change. A study by the Food and Climate Research Network in 2017 has concluded that Savory's claims about carbon sequestration are "unrealistic" and very different from those issued by peer-reviewed studies. The FCRN study estimates that, on the basis of meta-study of the scientific literature, the total global soil carbon sequestration potential from grazing management ranges from 0.3-0.8 Gt CO2eq per year, which is equivalent to offsetting a maximum of 4-11% of current total global livestock emissions, and that “Expansion or intensification in the grazing sector as an approach to sequestering more carbon would lead to substantial increases in methane, nitrous oxide and land use change-induced CO2 emissions” Project Drawdown estimates the total carbon sequestration potential of improved managed grazing at 13.72 - 20.92 Gigatons CO2eq between 2020–2050, equal to 0.46-0.70 Gt CO2eq per year. A 2022 peer-reviewed paper estimated the carbon sequestration potential of improved grazing management at a similar level of 0.15-0.70 Gt CO2eq per year. Awards Savory received the 2003 Banksia International Award and in 2010 the Africa Centre for Holistic Management in Zimbabwe, Operation Hope (a "proof of concept" project using Holistic Management) was named the winner of the 2010 Buckminster Fuller Challenge for "recognizing initiatives which take a comprehensive, anticipatory, design approach to radically advance human well being and the health of our planet's ecosystems". In addition, numerous Holistic Management practitioners have received awards for their environmental stewardship through using Holistic Management practices.

Biopiracy

Biopiracy (also known as scientific colonialism) is the unauthorized appropriation of knowledge and genetic resources of farming and indigenous communities by individuals or institutions seeking exclusive monopoly control through patents or intellectual property. While bioprospecting is the act of exploring natural resources for undiscovered chemical compounds with medicinal or anti-microbial properties, commercial success from bioprospecting leads to the company's attempt at protecting their intellectual property rights on indigenous medicinal plants, seeds, genetic resources, and traditional medicines. Moreover, if biological resources and traditional knowledge are taken from indigenous or marginalized groups, the commercialization of their natural resource can harm communities. Despite the medicinal and innovative benefits of bioprospecting and biochemical research, the expropriation of indigenous land for their genetic resources without fair compensation inevitably leads to exploitation. Biopiracy can harm indigenous populations in multiple ways. Without proper compensation or reward for traditional knowledge of natural resources, the sudden increase in commercial value of the species producing the active compound can make it now unaffordable for the native people. In some cases, a patent filed by the western company could prohibit the use or sale of the resource by any individual or institution, including the indigenous group. With nearly one third of all small-molecule drugs approved by the U.S. Food and Drug Administration (FDA) between 1981 and 2014 being either natural products or compounds derived from natural products, bioprospecting or piracy is growing more significantly, especially in the pharmaceutical industry. Furthermore, the United Nations Educational, Scientific and Cultural Organization (UNESCO) mentions, in the context of intangible cultural heritage (ICH), that the medicinal traditions and knowledge of the Kallawaya communities in Peru have been affected by the lack of legal protection from pharmaceutical companies. A number of research projects are currently being developed on this subject, such as the research carried out using digital methods on the biopiracy of traditional medicines, which shows the current context of the problem by developing a description and analysis of the data, and by visualising and mapping the various organisations and actors in the social networks. With the advancement of extraction techniques of genetic material in biochemistry and molecular biology, scientists are now able to identify a specific gene, which directs to enzymes capable of converting one molecule to another. This scientific breakthrough brings up the question of whether the organism containing the gene that has been modified through a series of tests and experiments should be accredited to the country of origin. History Colonial implications Biopiracy is historically associated with colonialism, where developing resource-rich countries and indigenous populations would be exploited without permission. Since the arrival of European settlers in search of gold, silver, and rare spices, the wealth of knowledge on plant-based riches was highly valued. Following Marco Polo's journey through Southwestern India and China, Christopher Columbus expanded upon the "Spice Route" with the help of the Spanish Court. These explorers, amongst hundreds more, share an infamous history of pillaging through indigenous villages and depriving countries of their natural resources. Western food and pharmaceutical companies have profited immensely from these efforts. Valuable commodities like sugar, pepper, quinine, and coffee were all taken from colonized countries that led to environmental destructions in the corresponding developing countries. The General Agreement on Tariffs and Trade (GATT) of 1947 was an effort to encourage international trade by reducing or eliminating trade barriers like tariffs or quotas. Trade-Related Intellectual Property Rights (TRIPS) was negotiated at the end of GATT. Similarly, Columbus set a precedent in 1492 through land titles granted by European kings and queens, which acted as a sort of patent for colonizers. The World Trade Organization (WTO) agreement of TRIPS attempts to signal the importance of maintaining a balance between trade and intellectual property. This agreement, since 1994, requires WTO member countries to develop legal frameworks to protect plant and animal resources in agricultural, pharmaceutical, chemical, textile, or other commodity contexts. Several countries have criticized this agreement, claiming that it's counterproductive in protecting their natural resources. The Eurocentric roots of property claiming and piracy are reinforced by modern Intellectual Property laws established by GATT and WTO which supplements the colonial ideas to "discover and conquer" and to "subdue, occupy, and possess." Environmental activist and food sovereignty advocate Vandana Shiva calls patenting and claiming rights to genetic material and bio-resources "the second coming of Columbus" due to its reinforcement of colonial power dynamics. For example, the intellectual property for Indian products like tamarind, turmeric, and Darjeeling tea have been taken and patented by private corporations in historically colonial countries. More specifically, in 2010 The University of Michigan attempted to patent curcumin, the active ingredient of turmeric powder, to create drugs used for wound healing without directly crediting Indian communities, where turmeric was traditionally used in medicine for treating wounds, infections and skin problems for centuries. "Gene Rush" in Sri Lanka The "Gene Rush" is the new era of biotechnology that allows scientists to extract specific genes from living organisms as raw materials. With the introduction of deoxyribonucleic acid (DNA) research, Sri Lanka has been marked with imminent danger as a target of biopiracy. Spotted in the top 34 biodiversity hotspots, Sri Lanka claims the highest biodiversity per unit area of terrestrial among Asian countries. Currently, Sri Lanka has 1,500 identified species of medicinal herbs and plants, and its attraction to biopiracy has put environment protection and conservation at a significant priority in the country. Recent efforts were enacted by United Nations Industrial Development Organization (UNIDO) in collaboration with the Spice Council and the government of Sri Lanka to enhance the productive capacities and competitiveness of the cinnamon value chain in the country. Terminology "Biopiracy" was coined in the early 1990s by Pat Mooney, founder of ETC Group which works to protect the world's most vulnerable people from socioeconomic and environmental impacts of new, modern technologies. He defines it as when researchers or research organizations take biological resources without official sanction, largely from less affluent countries or marginalized people. Biopiracy includes theft or misappropriation of genetic resources and traditional knowledge through the intellectual property system and unauthorized and uncompensated collection of genetic resources for commercial purposes. Mooney, along with other critics of the patent system, believes that the current intellectual property system creates inequities in the system by allowing wealthy and powerful groups of people to own the most basic building blocks of life. Intellectual Property and international law Intellectual property (IP) rights include patents, copyright, industrial design rights, trademarks, plant variety rights, trade dress, geographical indications, and sometimes trade secrets. Intellectual property rights (IPR) were created to promote and reward scientific knowledge and creativity. However, they naturally weigh towards benefiting transnational corporations. Restrictions in favor of corporations Early intellectual property treaties were crafted in the late 19th century by European powers, and inherently ignored large parts of the impact of intellectual property on non-European peoples, cultures, and traditions. In the late 20th century, more inequalities were added to the intellectual property system, representing a shift from common rights to private rights of knowledge. The preamble of TRIPS agreement acknowledges these rights as private rights. By privatizing intellectual commons, TRIPS encourages corporate monopoly. A second restriction comes from the fact that IP rights are only recognized when they generate profit, rather than then when they meet social needs. The TRIPS agreement clarifies that an innovation must be capable of industrial profit in order to be recognized as an IPR, which discourages recognition of social good. Legal framework against biopiracy in relation to genetic resources and traditional knowledge In parallel, the international community has been working on different legal pathways to rebalance the intellectual property system in favour of indigenous peoples and local communities, in an attempt to address concerns related to biopiracy. 1992–2010: Biodiversity Convention in Rio & Protocol in Nagoya First elements related to genetic resources and traditional knowledge were included in the 1992 Convention on Biological Diversity (CBD). In 2010 (in force 2014), the Nagoya protocol to the CBD created actionable mechanisms to ensure a fair access and benefit-sharing (FABS or ABS) of genetic resources (GR). 2023: High Seas Treaty in New York In June 2023, the UN adopted the United Nations agreement on biodiversity beyond national jurisdiction (BBNJ Agreement), also called "High Seas Treaty". It concerns the conservation and sustainable use of marine biological diversity in areas beyond national jurisdiction, following maritime jurisdictions established under the United Nations Convention on the Law of the Sea. 2024: GRATK Treaty in Geneva Since 2001, the World Intellectual Property Organization through its Intergovernmental Committee on Intellectual Property and Genetic Resources, Traditional Knowledge and Folklore (IGC) has worked on several areas to bridge the gaps in international law in relation to biopiracy in genetic resources, traditional knowledge (TK), and traditional cultural expressions (TCE, formerly called "folklore"). The first output from the work of the IGC was a Diplomatic Conference, held in May 2024 to agree on a treaty for patent disclosures requirements in relation to "GR and Associated TK" (hence the treaty's acronym, GRATK). On 24 May 2024, the WIPO Diplomatic Conference finally adopted the "landmark" WIPO Treaty on Intellectual Property, Genetic Resources and Associated Traditional Knowledge (GRATK), which was signed by 30 countries on the day of its conclusion. Examples Neem tree In the arid areas of India, the neem tree, or Azadirachta indica, is a fast-growing evergreen of up to 20 meters in height. From its roots to leaves, the tree contains a number of potent chemical compounds, including azadirachtin which can be found in the seeds. The neem tree has applications in medicine, toiletries, contraception, timber, fuel, and in agriculture. Historically, access to the neem tree's various products has been free or cheap. There are about 14 million neem trees in India, and the centuries old village techniques of seed oil extraction and pesticidal emulsions do not require expensive equipment. Villagers relied on the large number of different medicinal compounds accessible through the neem material which were commonly available. When US timber importer Robert Larson noticed the tree's usefulness in 1971, he conducted research over the next decade on the pesticidal properties in the neem extract called Margosan-O. After gaining clearance for the product from the US Environmental Protection Agency (EPA) in 1985, he sold the patent for the product to W.R. Grace. While the corporation patented the neem tree seed extract for their antifungal spray, Neemex in 1994, neem extracts have been used by rural farmers in India for more than 2,000 years in insect repellants. Challenge against patent India-based Research Foundation for Science, Technology, and Ecology (RFSTE) challenged the US patent with the claim that the qualities of the neem tree and their use had been known in India for over 2,000 years. The Congressional Research Service (CRS) reported to US Congress in justification of the patent claiming that the synthetic form or the process of synthesis of the naturally occurring compound should be patentable. The patent was finally overturned by the EPO in 2000. The village neem tree has become a symbol of Indian Indigenous knowledge and resistance against transnational corporations, and protestors against international property rights legislation carried twigs or branches of neem. Hoodia The Hoodia plant of the Kalahari Desert was used for thousands of years by the nomadic San people in southern Africa to help survive through hunger and thirst during their long expeditions in the desert. In 2016, the South African Council for Scientific and Industrial Research (CSIR) gained a government-funded patent for a new drug (P57) derived from the succulent for its appetite-suppressing qualities. CSIR scientists isolated the P57 molecule in 1996 after decades of research on indigenous plants. The patented formula was sold to western pharmaceutical multinational companies Pfizer and Phytopharm as a miracle drug for weight loss. Challenge against patent Following the confirmation of the patent, representatives of the San people, backed by the global support of patent-law critics and bioethicists, demanded restitution of their rights to their common intellectual property. After a long dispute, CSIR and the San people came to a confidential 'benefit-sharing' agreement where the San people were given royalties, knowledge exchange and creation of jobs from the industry. Pineapple leather Piña cloth, in the nineteenth century, was a creation unique to the Philippines. With fibers collected from the leaves of pineapples, the weaving mechanism of piña is a complex and labor-intensive process used by a small number of women to dress the country's elite. Scraping, the most common method of extracting pineapple leaf fibre (PALF), starts with carefully removing the prickles, epidermis, and pulp from the sides of the leaf with a dull knife. This is followed by exposing the fiber and finely combing it to separate the strands. With the help of a bamboo device, the separated strands are then threaded and weaved together through a delicate process to create a continuous filament. After some years of research and development of potential leather alternatives at the Royal College of Art in London, Dr. Carmen Hijosa, founder and chief creative innovation officer of Ananas Anam, claimed the rights to Piñatex, a leather alternative made from PALF. The patent on this technology makes it nearly impossible for the people of the Philippines and indigenous people to gain credit for the fabric that greatly impacted the shape of their history and culture for generations. Piñatex recently partnered with Dole, promising scaled-up leather production with the waste product from their pineapple farms in the Philippines. Despite the violent history of the Dole Empire, Piñatex has been expanding its market by collaborating with brands like Chanel, H&M, and Nike. The patent remains to this day. Corporate greenwashing Greenwashing is a term coined by environmentalist Jay Westervelt in 1986, meaning the false claims by companies that give the impression of sustainability and environmentalism. Without clarifying the metrics and quantifiable goal of the company's environmental agenda, many big companies attempt to paint the picture of ethical and eco-friendly images. Resources and materials pirated from indigenous communities are often commodified and recycled into corporate environmentalist agendas. Due to the exploitative nature of the fast fashion supply chain, many 'green' collections released by corporations only promote their marketing strategies and increase problems with textile waste and climate change. Nike received backlash after the 2020 Impact Report which showed the lack of sustainability in footwear. To tackle the feedback, Nike launched the Happy Pineapple Collection featuring Ananas Anam's vegan leather material and a tropical fruit design embroidered across the Air Max 90, the Air Max 95, Air Force One, and Air-Zoom collections. The Conscious Collection released by H&M in 2010 also partners with Ananas Anam to produce vegan leather jackets. Due to inconclusive data on Piñatex biodegradability, the Norwegian Consumer Authority accused the brand of misleading customers with vague details of the sustainability claims made. The brand responded by saying they would accept the criticism and communicate the extra value. New efforts The Convention on Biological Diversity created by the United Nations in 1992 demanded that bioprospecting should not be done without the consent of the host country. The convention concluded that exploitation of local resources for medicinal and pharmaceutical purposes should actively involve local traditional communities and the produced profit and benefits be shared in an equitable way. The International Cooperative Biodiversity Group (ICBG) is a network of bioprospecting projects funded by the US government. While the main objective is to discover and research plants bearing chemical compounds that could cure diseases in the United States, the countries hosting the searches can expect equitable rewards and benefits. Local job creation in communities is promoted by conducting the initial extraction and analysis steps in local laboratories. If the research leads to commercialized drugs, 50% of the royalties are invested into community development funds run by indigenous people.

Weak and strong sustainability

Weak and strong sustainability are terms that have emerged from the field of environmental economics and describe opposing approaches to sustainability, specifically in relation to natural resource management and economic development. Weak sustainability argues that natural and human capital are interchangeable, meaning that the use or loss of natural capital can be considered sustainable if the human capital meets or exceeds the value of the natural capital. It assumes that different types of value can be measured and given value in the same way. Strong sustainability argues that natural capital should be maintained or enhanced independently of human-made capital. It considers that certain natural assets are incommensurable and have critical ecological functions that cannot be substituted by human-made alternatives. For example, according to weak sustainability, replacing a natural forest with a park or agricultural land can be considered sustainable if the recreational or economic value equal the value of the biodiversity lost and further environmental impact caused. According to strong sustainability, cutting down trees in a natural forest and planting new trees elsewhere cannot be considered sustainable, as the value of biodiversity was lost and wider ecological implications cannot truly be measured or offset. One of the first pieces of work to discuss these ideas was "Blueprint for a Green Economy" by Pearce, Markandya, and Barbier, published in 1989. This work laid the foundations for further discussion on the substitutability of natural capital (e.g., forests, water, and clean air) and human-made capital (e.g., buildings, machinery, and technology), and the implications for long-term ecological and economic health. Origins and theory Capital approach to sustainability and intergenerational equity To understand the concept of weak sustainability, it is first necessary to explore the capital approach to sustainability. This is key to the idea of intergenerational equity. This implies that a fair distribution of resources and assets between generations exists. Decision makers, both in theory and practice, need a concept that enables assessment in order to decide if intergenerational equity is achieved. The capital approach lends itself to this task. In this context we must distinguish between the different types of capital. Human capital (e.g. skills, knowledge) and natural capital (e.g. minerals, water) tend to be the most frequently cited examples. Within the concept it is believed that the amount of capital a generation has at its disposal is decisive for its development. A development is then called sustainable when it leaves the capital stock at least unchanged. Sustainable development Although related, sustainable development and sustainability are two different concepts. Weak sustainability is an idea based upon the work of Nobel laureate Robert Solow, and John Hartwick. which states that 'human capital' can substitute 'natural capital'. The weak sustainability paradigm stems from the 1970s. It began as an extension of the neoclassical theory of economic growth, accounting for non-renewable natural resources as a factor of production. However, it only really came into the mainstream in the 1990s as the idea received more political attention as sustainable development discussions evolved in the late 1980s and early 1990s. A key landmark was the Rio Summit in 1992 where the vast majority of nation-states committed themselves to sustainable development. This commitment was demonstrated by the signing of Agenda 21, a global action plan on sustainable development. At its inception, sustainability was interpreted as a requirement to preserve, intact, the environment as we find it today in all its forms. The Brundtland Report, for example, stated that ‘The loss of plant and animal species can greatly limit the options of future generations. The result is that sustainable development requires the conservation of plant and animal species’. Development of theory Wilfred Beckerman posits that the absolutist concept of sustainable development given above is morally repugnant. The largest part of the world's population live in acute poverty. Taking that as well as the acute degradation into account, one could justify using up vast resources in an attempt to preserve certain species from extinction. These species providing no real benefit for society other than a possible value for the knowledge of their continued existence. He argues that such a task would involve using resources that could have instead been devoted to more pressing world concerns. Examples include increasing access to clean drinking water or sanitation in the Third World. Many environmentalists shifted their attention to the idea of ‘weak’ sustainability. This allows for some natural resources to decrease as long as sufficient compensation is provided by increases in other resources. The result usually was an increase in human capital. This compensation is in the form of sustained human welfare. This is illustrated in a well-regarded definition by David Pearce, the author of numerous works on sustainability. He defines sustainability as implying something about maintaining the level of human welfare (or well-being) so that it may improve, but never declines (or, not more than temporarily). This implies sustainable development will not decrease over time. Inter-generational equity assumes each following generation has at least as much capital at its disposal as the preceding generation. The idea of leaving capital stock at least unchanged is widely accepted. The question arises, whether or not one form of capital may be substituted by another. This is the focus of the debate between ‘weak’ and ‘strong’ sustainability, and how intergenerational equity is to be achieved. Strong sustainability argument Strong sustainability does not share the notion of inter-changeability; it assumes that economic and environmental capital are complementary but not interchangeable. Since the nineties, there has been an ardent debate on the substitutability between natural and human-made capital. While "Weak Sustainability" supporters mainly believe that these are substitutable, "Strong Sustainability" followers generally contest the possibility of inter-changeability. Strong sustainability accepts there are certain functions that the environment performs that cannot be duplicated by humans or human made capital. The ozone layer is one example of an ecosystem service that is crucial for human existence, forms part of natural capital, but is difficult for humans to duplicate. Unlike weak sustainability, strong sustainability puts the emphasis on ecological scale over economic gains. This implies that nature has a right to exist and that it has been borrowed and should be passed on from one generation to the next still intact in its original form. One version of strong sustainability is in defining and respecting hard boundaries and limits in relation to planetary boundaries. This attempts to give incommensurable value to certain environmental changes or actions. Weak sustainability in practice Weak sustainability has been defined using concepts like human capital and natural capital. Human (or produced) capital incorporates resources such as infrastructure, labour and knowledge. Natural capital covers the stock of environmental assets such as fossil fuels, biodiversity and other ecosystem structures and functions relevant for ecosystem services. In very weak sustainability, the overall stock of man-made capital and natural capital remains constant over time. It is important to note that, unconditional substitution between the various kinds of capital is allowed within weak sustainability. This means that natural resources may decline as long as human capital is increased. Examples include the degradation of the ozone layer, tropical forests and coral reefs if accompanied by benefits to human capital. An example of the benefit to human capital could include increased financial profits. If capital is left constant over time intergenerational equity, and thus Sustainable Development, is achieved. An example of weak sustainability could be mining coal and using it for production of electricity. The natural resource coal, is replaced by a manufactured good which is electricity. The electricity is then in turn used to improve domestic life quality (e.g. cooking, lighting, heating, refrigeration and operating boreholes to supply water in some villages) and for industrial purposes (growing the economy by producing other resources using machines that are electricity operated.) Case studies of weak sustainability in practice have had both positive and negative results. The concept of weak sustainability still attracts a lot of criticism. Some even suggest that the concept of sustainability is redundant. Other approaches are advocated, including ‘social bequests’, which focus the attention away from neoclassical theory altogether. A prime example of a weak sustainability is the Government Pension Fund of Norway. Statoil ASA, a state-owned Norwegian oil company invested its surplus profits from petroleum into a pension portfolio to date worth over $1 trillion. The oil, a type of natural capital, was exported in vast quantities by Norway. The resultant fund allows for long-lasting income for the population in exchange for a finite resource, actually increasing the total capital available for Norway above the original levels. This example shows how weak sustainability and substitution can be cleverly applied on a national scale, although it is recognised that its applications are very restricted on a global scale. In this application, Hartwick's rule would state that the pension fund was sufficient capital to offset the depletion of the oil resources. A less positive case is that of the small Pacific nation of Nauru. A substantial phosphate deposit was found on the island in 1900, and now approximately 80% of the island has been rendered uninhabitable after over 100 years of mining. Concurrent with this extraction, Nauru's inhabitants, over the last few decades of the twentieth century, have enjoyed a high per capita income. Money from the mining of phosphate enabled the establishment of a trust fund, which was estimated to be as much as $1 billion. However, chiefly as a result of the Asian financial crisis, the trust fund was almost entirely wiped out. This ‘development’ of Nauru followed the logic of weak sustainability, and almost led to complete environmental destruction. This case presents a telling argument against weak sustainability, suggesting that a substitution of natural for man-made capital may not be reversible in the long-term. Role of governance and policy recommendations The implementation of weak sustainability in governance can be viewed theoretically and practically through Hartwick's rule. In resource economics, Hartwick's rule defines the amount of investment in human capital that is needed to offset declining stocks of non-renewable resources. Solow showed that, given a degree of substitutability between human capital and natural capital, one way to design a sustainable consumption program for an economy is to accumulate man-made capital. When this accumulation is sufficiently rapid the effect from the shrinking exhaustible resource stock is countered by the services from the increased human capital stock. Hartwick's rule, is often referred to as "invest resource rents", where ‘rent’ is payment to a factor of production (in this case capital) in excess of that needed to keep it in its present use. This requires that a nation invest all rent earned from exhaustible resources currently extracted. Later, Pearce and Atkinson and Hamilton added to Hartwick's rule, by setting out a theoretical and empirical measure of net investment in human and natural capital (and later human capital) that became known as genuine savings. Genuine savings measures net changes in produced, natural and human capital stocks, valued in monetary terms. The aim of governance therefore should be to keep genuine savings above or equal to zero. In this sense it is similar to green accounting, which attempts to factor environmental costs into the financial results of operations. A key example of this is the World Bank, who now regularly publishes a comparative and comprehensive set of genuine savings estimates for over 150 countries which is called ‘adjusted savings’. Criticisms of the strong vs. weak sustainability model Martinez-Allier's address concerns over the implications of measuring weak sustainability, after results of work conducted by Pearce & Atkinson in the early 1990s. By their measure, most of the Northern, industrialised countries are deemed sustainable, as is the world economy as a whole. This point of view can be considered to be flawed since the world would (arguably) not be sustainable if all countries have the resource intensity rate and pollution rate of many industrialised countries. Industrialization does not necessarily equate to sustainability. According to Pearce and Atkinson's calculations, the Japanese economy is one of the most sustainable economies in the world. The reason for this is that its saving rate is so high. This trend still remains today and therefore exceeds depreciation on both natural and man-made capital. Thus, they suggest that it is the gross negligence of factors other than savings in measuring sustainability that makes weak sustainability an inappropriate concept. The integrative sustainability model has the economy completely located within society and society completely located within the environment. In other words, the economy is a subset of society and society is completely dependent upon the environment. This interdependence means that any sustainability-related issue must be considered holistically. Other inadequacies of the paradigm include the difficulties in measuring savings rates and the inherent problems in quantifying the many different attributes and functions of the biophysical world in monetary terms. By including all human and biophysical resources under the same heading of ‘capital’, the depleting of fossil fuels, reduction of biodiversity and so forth, are potentially compatible with sustainability. As Gowdy & O'Hara so aptly put it, "As long as the criterion of weak sustainability is met, with savings outstripping capital depletion, there is no conflict between the destruction of species and ecosystems or the depletion of fossil fuels, and the goal of sustainability." Opposing weak sustainability, strong sustainability supporters contend that we need "a more small-scale decentralized way of life based upon greater self-reliance, so as to create a social and economic system less destructive towards nature." Strong sustainability does not make allowances for the substitution of human, and human made capital for Earth's land, water, and their biodiversity. The products created by mankind cannot replace the natural capital found in ecosystems. Another critical weakness of the concept is related to environmental resilience. According to Van Den Bergh, resilience can be considered as a global, structural stability concept, based on the idea that multiple, locally stable ecosystems can exist. Sustainability can thus be directly related to resilience. With this in mind, weak sustainability can cause extreme sensitivity to either natural disturbances (such as diseases in agriculture with little crop diversity) or economic disturbances (as outlined in the case study of Nauru above). This high level of sensitivity within regional systems in the face of external factors brings to attention an important inadequacy of weak sustainability. Rejection of both weak and strong models Some critics dismiss the entire concept of sustainability. Beckerman's influential work concludes that weak sustainability is “redundant and illogical”. He holds that sustainability only makes sense in its 'strong' form, but that "requires subscribing to a morally repugnant and totally impracticable objective." He also says that he regrets that so much time has been wasted on the entire concept of sustainable development. Others have suggested that a better approach to sustainability would be that of social bequests. This approach is intended to "free us from a 'zero-sum' game in which our gain is an automatic loss for future generations". The social bequest approach reframes the problem to focus on what we leave to future generations rather than how much; the argument is that when the problem is phrased as ‘how much,' this implies that some amount of a resource should be used, and some amount should be left. Daniel Bromley uses the example of rainforests to illustrate his argument: If we decide to use 25% of a rainforest and leave the rest, but then the next time we make a decision we start all over again and use 25% of what's left, and so on, eventually there will be no rainforest left. By focusing on bequests of specific rights and opportunities for future generations, we can remove ourselves from the "straightjacket of substitution and marginal tradeoffs of neoclassical theory".

Emic and etic

In anthropology, folkloristics, linguistics, and the social and behavioral sciences, emic and etic refer to two kinds of field research done and viewpoints obtained. The "emic" approach is an insider's perspective, which looks at the beliefs, values, and practices of a particular culture from the perspective of the people who live within that culture. This approach aims to understand the cultural meaning and significance of a particular behavior or practice, as it is understood by the people who engage in it. The "etic" approach, on the other hand, is an outsider's perspective, which looks at a culture from the perspective of an outside observer or researcher. This approach tends to focus on the observable behaviors and practices of a culture, and aims to understand them in terms of their functional or evolutionary significance. The etic approach often involves the use of standardized measures and frameworks to compare different cultures and may involve the use of concepts and theories from other disciplines, such as psychology or sociology. The emic and etic approaches each have their own strengths and limitations, and each can be useful in understanding different aspects of culture and behavior. Some anthropologists argue that a combination of both approaches is necessary for a complete understanding of a culture, while others argue that one approach may be more appropriate depending on the specific research question being addressed. Definitions "The emic approach investigates how local people think...". How they perceive and categorize the world, their rules for behavior, what has meaning for them, and how they imagine and explain things. "The etic (scientist-oriented) approach shifts the focus from local observations, categories, explanations, and interpretations to those of the anthropologist. The etic approach realizes that members of a culture often are too involved in what they are doing... to interpret their cultures impartially. When using the etic approach, the ethnographer emphasizes what he or she considers important." Although emics and etics are sometimes regarded as inherently in conflict and one can be preferred to the exclusion of the other, the complementarity of emic and etic approaches to anthropological research has been widely recognized, especially in the areas of interest concerning the characteristics of human nature as well as the form and function of human social systems. Emic and etic approaches of understanding behavior and personality fall under the study of cultural anthropology. Cultural anthropology states that people are shaped by their cultures and their subcultures, and we must account for this in the study of personality. One way is looking at things through an emic approach. This approach "is culture specific because it focuses on a single culture and it is understood on its own terms." As explained below, the term "emic" originated from the specific linguistic term "phonemic", from phoneme, which is a language-specific way of abstracting speech sounds. An 'emic' account is a description of behavior or a belief in terms meaningful (consciously or unconsciously) to the actor; that is, an emic account comes from a person within the culture. Almost anything from within a culture can provide an emic account. An 'etic' account is a description of a behavior or belief by a social analyst or scientific observer (a student or scholar of anthropology or sociology, for example), in terms that can be applied across cultures; that is, an etic account attempts to be 'culturally neutral', limiting any ethnocentric, political or cultural bias or alienation by the observer. When these two approaches are combined, the "richest" view of a culture or society can be understood. On its own, an emic approach would struggle with applying overarching values to a single culture. The etic approach is helpful in enabling researchers to see more than one aspect of one culture, and in applying observations to cultures around the world. History The terms were coined in 1954 by linguist Kenneth Pike, who argued that the tools developed for describing linguistic behaviors could be adapted to the description of any human social behavior. As Pike noted, social scientists have long debated whether their knowledge is objective or subjective. Pike's innovation was to turn away from an epistemological debate, and turn instead to a methodological solution. Emic and etic are derived from the linguistic terms phonemic and phonetic, respectively, where a phone is a distinct speech sound or gesture, regardless of whether the exact sound is critical to the meanings of words, whereas a phoneme is a speech sound in a given language that, if swapped with another phoneme, could change one word to another. The possibility of a truly objective description was discounted by Pike himself in his original work; he proposed the emic-etic dichotomy in anthropology as a way around philosophic issues about the very nature of objectivity. The terms were also championed by anthropologists Ward Goodenough and Marvin Harris with slightly different connotations from those used by Pike. Goodenough was primarily interested in understanding the culturally specific meaning of specific beliefs and practices; Harris was primarily interested in explaining human behavior. Pike, Harris, and others have argued that cultural "insiders" and "outsiders" are equally capable of producing emic and etic accounts of their culture. Some researchers use "etic" to refer to objective or outsider accounts, and "emic" to refer to subjective or insider accounts. Margaret Mead was an anthropologist who studied the patterns of adolescence in Samoa. She discovered that the difficulties and the transitions that adolescents faced are culturally influenced. The hormones that are released during puberty can be defined using an etic framework, because adolescents globally have the same hormones being secreted. However, Mead concluded that how adolescents respond to these hormones is greatly influenced by their cultural norms. Through her studies, Mead found that simple classifications about behaviors and personality could not be used because peoples’ cultures influenced their behaviors in such a radical way. Her studies helped create an emic approach of understanding behaviors and personality. Her research deduced that culture has a significant impact in shaping an individual's personality. Carl Jung, a Swiss psychoanalyst, is a researcher who took an emic approach in his studies. Jung studied mythology, religion, ancient rituals, and dreams, leading him to believe that there are archetypes that can be identified and used to categorize people's behaviors. Archetypes are universal structures of the collective unconscious that refer to the inherent way people are predisposed to perceive and process information. The main archetypes that Jung studied were the persona (how people choose to present themselves to the world), the anima and animus (part of people experiencing the world in viewing the opposite sex, that guides how they select their romantic partner), and the shadow (dark side of personalities because people have a concept of evil; well-adjusted people must integrate both good and bad parts of themselves). Jung looked at the role of the mother and deduced that all people have mothers and see their mothers in a similar way; they offer nurture and comfort. His studies also suggest that "infants have evolved to suck milk from the breast, it is also the case that all children have inborn tendencies to react in certain ways." This way of looking at the mother is an emic way of applying a concept cross-culturally and universally. Importance as regards personality Emic and etic approaches are important to understanding personality because problems can arise "when concepts, measures, and methods are carelessly transferred to other cultures in attempts to make cross-cultural generalizations about personality." It is hard to apply certain generalizations of behavior to people who are so diverse and culturally different. One example of this is the F-scale (Macleod). The F-scale, which was created by Theodor Adorno, is used to measure authoritarian personality, which can, in turn, be used to predict prejudiced behaviors. This test, when applied to Americans accurately depicts prejudices towards black individuals. However, when a study was conducted in South Africa using the F-Scale, (Pettigrew and Friedman) results did not predict any prejudices towards black individuals. This study used emic approaches of study by conducting interviews with the locals and etic approaches by giving participants generalized personality tests.

Sustainable development

Sustainable development is an approach to growth and human development that aims to meet the needs of the present without compromising the ability of future generations to meet their own needs. The aim is to have a society where living conditions and resources meet human needs without undermining planetary integrity. Sustainable development aims to balance the needs of the economy, environment, and social well-being. The Brundtland Report in 1987 helped to make the concept of sustainable development better known. Sustainable development overlaps with the idea of sustainability which is a normative concept. UNESCO formulated a distinction between the two concepts as follows: "Sustainability is often thought of as a long-term goal (i.e. a more sustainable world), while sustainable development refers to the many processes and pathways to achieve it." There are some problems with the concept of sustainable development. Some scholars say it is an oxymoron because according to them, development is inherently unsustainable. Other commentators are disappointed in the lack of progress that has been achieved so far. Part of the problem is that development itself is not consistently defined. The Rio Process that began at the 1992 Earth Summit in Rio de Janeiro has placed the concept of sustainable development on the international agenda. In 2015 the United Nations General Assembly (UNGA) adopted the Sustainable Development Goals for the year 2030. These development goals address the global challenges, including for example poverty, climate change, biodiversity loss, and peace. Definition of sustainable development In 1987, the United Nations World Commission on Environment and Development released the report Our Common Future, commonly called the Brundtland Report. The report included a definition of "sustainable development" which is now widely used: Sustainable development thus tries to find a balance between economic development, environmental protection, and social well-being. Related concepts Sustainability Development of the concept Sustainable development has its roots in ideas regarding sustainable forest management, which were developed in Europe during the 17th and 18th centuries. In response to a growing awareness of the depletion of timber resources in England, John Evelyn argued, in his 1662 essay Sylva, that "sowing and planting of trees had to be regarded as a national duty of every landowner, in order to stop the destructive over- exploitation of natural resources." In 1713, Hans Carl von Carlowitz, a senior mining administrator in the service of Elector Frederick Augustus I of Saxony published Sylvicultura economics, a 400-page work on forestry. Building upon the ideas of Evelyn and French minister Jean-Baptiste Colbert, von Carlowitz developed the concept of managing forests for sustained yield. His work influenced others, including Alexander von Humboldt and Georg Ludwig Hartig, eventually leading to the development of the science of forestry. This, in turn, influenced people like Gifford Pinchot, the first head of the US Forest Service, whose approach to forest management was driven by the idea of wise use of resources, and Aldo Leopold whose land ethic was influential in the development of the environmental movement in the 1960s. Following the publication of Rachel Carson's Silent Spring in 1962, the developing environmental movement drew attention to the relationship between economic growth and environmental degradation. Kenneth E. Boulding, in his influential 1966 essay The Economics of the Coming Spaceship Earth, identified the need for the economic system to fit itself to the ecological system with its limited pools of resources. Another milestone was the 1968 article by Garrett Hardin that popularized the term "tragedy of the commons". The direct linking of sustainability and development in a contemporary sense can be traced to the early 1970s. "Strategy of Progress", a 1972 book (in German) by Ernst Basler, explained how the long-acknowledged sustainability concept of preserving forests for future wood production can be directly transferred to the broader importance of preserving environmental resources to sustain the world for future generations. That same year, the interrelationship of environment and development was formally demonstrated in a systems dynamic simulation model reported in the classic report on Limits to Growth. This was commissioned by the Club of Rome and written by a group of scientists led by Dennis and Donella Meadows of the Massachusetts Institute of Technology. Describing the desirable "state of global equilibrium", the authors wrote: "We are searching for a model output that represents a world system that is sustainable without sudden and uncontrolled collapse and capable of satisfying the basic material requirements of all of its people." The year 1972 also saw the publication of the influential book, A Blueprint for Survival. In 1975, an MIT research group prepared ten days of hearings on "Growth and Its Implication for the Future" for the US Congress, the first hearings ever held on sustainable development. In 1980, the International Union for Conservation of Nature published a world conservation strategy that included one of the first references to sustainable development as a global priority and introduced the term "sustainable development". Two years later, the United Nations World Charter for Nature raised five principles of conservation by which human conduct affecting nature is to be guided and judged. Since the Brundtland Report, the concept of sustainable development has developed beyond the initial intergenerational framework to focus more on the goal of "socially inclusive and environmentally sustainable economic growth". In 1992, the UN Conference on Environment and Development published the Earth Charter, which outlines the building of a just, sustainable, and peaceful global society in the 21st century. The action plan Agenda 21 for sustainable development identified information, integration, and participation as key building blocks to help countries achieve development that recognizes these interdependent pillars. Furthermore, Agenda 21 emphasizes that broad public participation in decision-making is a fundamental prerequisite for achieving sustainable development. The Rio Protocol was a huge leap forward: for the first time, the world agreed on a sustainability agenda. In fact, a global consensus was facilitated by neglecting concrete goals and operational details. The Sustainable Development Goals (SDGs) now have concrete targets (unlike the results from the Rio Process) but no methods for sanctions. Dimensions Sustainable development, like sustainability, is regarded to have three dimensions: the environment, economy and society. The idea is that a good balance between the three dimensions should be achieved. Instead of calling them dimensions, other terms commonly used are pillars, domains, aspects, spheres. Pathways Six interdependent capacities are deemed to be necessary for the successful pursuit of sustainable development. These are the capacities to measure progress towards sustainable development; promote equity within and between generations; adapt to shocks and surprises; transform the system onto more sustainable development pathways; link knowledge with action for sustainability; and to devise governance arrangements that allow people to work together. Environmental sustainability Environmental sustainability concerns the natural environment and how it endures and remains diverse and productive. Since natural resources are derived from the environment, the state of air, water, and climate is of particular concern. Environmental sustainability requires society to design activities to meet human needs while preserving the life support systems of the planet. This, for example, entails using water sustainably, using renewable energy and sustainable material supplies (e.g. harvesting wood from forests at a rate that maintains the biomass and biodiversity). An unsustainable situation occurs when natural capital (the total of nature's resources) is used up faster than it can be replenished. Sustainability requires that human activity only uses nature's resources at a rate at which they can be replenished naturally. The concept of sustainable development is intertwined with the concept of carrying capacity. Theoretically, the long-term result of environmental degradation is the inability to sustain human life. Important operational principles of sustainable development were published by Herman Daly in 1990: renewable resources should provide a sustainable yield (the rate of harvest should not exceed the rate of regeneration); for non-renewable resources there should be equivalent development of renewable substitutes; waste generation should not exceed the assimilative capacity of the environment. Land use changes, agriculture and food Environmental problems associated with industrial agriculture and agribusiness are now being addressed through approaches such as sustainable agriculture, organic farming and more sustainable business practices. The most cost-effective climate change mitigation options include afforestation, sustainable forest management, and reducing deforestation. At the local level there are various movements working towards sustainable food systems which may include less meat consumption, local food production, slow food, sustainable gardening, and organic gardening. The environmental effects of different dietary patterns depend on many factors, including the proportion of animal and plant foods consumed and the method of food production. Materials and waste As global population and affluence have increased, so has the use of various materials increased in volume, diversity, and distance transported. Included here are raw materials, minerals, synthetic chemicals (including hazardous substances), manufactured products, food, living organisms, and waste. By 2050, humanity could consume an estimated 140 billion tons of minerals, ores, fossil fuels and biomass per year (three times its current amount) unless the economic growth rate is decoupled from the rate of natural resource consumption. Developed countries' citizens consume an average of 16 tons of those four key resources per capita per year, ranging up to 40 or more tons per person in some developed countries with resource consumption levels far beyond what is likely sustainable. By comparison, the average person in India today consumes four tons per year. Sustainable use of materials has targeted the idea of dematerialization, converting the linear path of materials (extraction, use, disposal in landfill) to a circular material flow that reuses materials as much as possible, much like the cycling and reuse of waste in nature. Dematerialization is being encouraged through the ideas of industrial ecology, eco design and ecolabelling. This way of thinking is expressed in the concept of circular economy, which employs reuse, sharing, repair, refurbishment, remanufacturing and recycling to create a closed-loop system, minimizing the use of resource inputs and the creation of waste, pollution and carbon emissions. Building electric vehicles has been one of the most popular ways in the field of sustainable development, the potential of using reusable energy and reducing waste offered a perspective in sustainable development. The European Commission has adopted an ambitious Circular Economy Action Plan in 2020, which aims at making sustainable products the norm in the EU. Biodiversity and ecosystem services There is a connection between ecosystems and biodiversity. Ecosystems are made up of various living things interacting with one another and their surroundings. Along with this, biodiversity lays the groundwork for ecosystems to function well by defining the kinds of species that can coexist in an environment, as well as their functions and interactions with other species. In 2019, a summary for policymakers of the largest, most comprehensive study to date of biodiversity and ecosystem services was published by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services. It recommended that human civilization will need a transformative change, including sustainable agriculture, reductions in consumption and waste, fishing quotas and collaborative water management. Biodiversity is not only crucial for the well-being of animals and wildlife but also plays a positive role in the lives of human beings in the way in which it aids development of human life. Management of human consumption and impacts The environmental impact of a community or humankind as a whole depends both on population and impact per person, which in turn depends in complex ways on what resources are being used, whether or not those resources are renewable, and the scale of the human activity relative to the carrying capacity of the ecosystems involved. Careful resource management can be applied at many scales, from economic sectors like agriculture, manufacturing and industry, to work organizations, the consumption patterns of households and individuals, and the resource demands of individual goods and services. The underlying driver of direct human impacts on the environment is human consumption. This impact is reduced by not only consuming less but also making the full cycle of production, use, and disposal more sustainable. Consumption of goods and services can be analyzed and managed at all scales through the chain of consumption, starting with the effects of individual lifestyle choices and spending patterns, through to the resource demands of specific goods and services, the impacts of economic sectors, through national economies to the global economy. Key resource categories relating to human needs are food, energy, raw materials and water. Improving on economic and social aspects It has been suggested that because of the rural poverty and overexploitation, environmental resources should be treated as important economic assets, called natural capital. Economic development has traditionally required a growth in the gross domestic product. This model of unlimited personal and GDP growth may be over. Sustainable development may involve improvements in the quality of life for many but may necessitate a decrease in resource consumption. "Growth" generally ignores the direct effect that the environment may have on social welfare, whereas "development" takes it into account. As early as the 1970s, the concept of sustainability was used to describe an economy "in equilibrium with basic ecological support systems". Scientists in many fields have highlighted The Limits to Growth, and economists have presented alternatives, for example a 'steady-state economy', to address concerns over the impacts of expanding human development on the planet. In 1987, the economist Edward Barbier published the study The Concept of Sustainable Economic Development, where he recognized that goals of environmental conservation and economic development are not conflicting and can be reinforcing each other. A World Bank study from 1999 concluded that based on the theory of genuine savings (defined as "traditional net savings less the value of resource depletion and environmental degradation plus the value of investment in human capital"), policymakers have many possible interventions to increase sustainability, in macroeconomics or purely environmental. Several studies have noted that efficient policies for renewable energy and pollution are compatible with increasing human welfare, eventually reaching a golden-rule steady state. A meta review in 2002 looked at environmental and economic valuations and found a "lack of concrete understanding of what "sustainability policies" might entail in practice". A study concluded in 2007 that knowledge, manufactured and human capital (health and education) has not compensated for the degradation of natural capital in many parts of the world. It has been suggested that intergenerational equity can be incorporated into a sustainable development and decision making, as has become common in economic valuations of climate economics. The World Business Council for Sustainable Development published a Vision 2050 document in 2021 to show "How business can lead the transformations the world needs". The vision states that "we envision a world in which 9+billion people can live well, within planetary boundaries, by 2050." This report was highlighted by The Guardian as "the largest concerted corporate sustainability action plan to date – include reversing the damage done to ecosystems, addressing rising greenhouse gas emissions and ensuring societies move to sustainable agriculture." Barriers Assessments and reactions The concept of sustainable development has been and still is, subject to criticism, including the question of what is to be sustained in sustainable development. It has been argued that there is no such thing as sustainable use of a non-renewable resource, since any positive rate of exploitation will eventually lead to the exhaustion of earth's finite stock; this perspective renders the Industrial Revolution as a whole unsustainable. The sustainable development debate is based on the assumption that societies need to manage three types of capital (economic, social, and natural), which may be non-substitutable and whose consumption might be irreversible. Natural capital can not necessarily be substituted by economic capital. While it is possible that we can find ways to replace some natural resources, it is much less likely that they will ever be able to replace ecosystem services, such as the protection provided by the ozone layer, or the climate stabilizing function of the Amazonian forest. The concept of sustainable development has been criticized from different angles. While some see it as paradoxical (or an oxymoron) and regard development as inherently unsustainable, others are disappointed in the lack of progress that has been achieved so far. Part of the problem is that "development" itself is not consistently defined. The vagueness of the Brundtland definition of sustainable development has been criticized as follows: The definition has "opened up the possibility of downplaying sustainability. Hence, governments spread the message that we can have it all at the same time, i.e. economic growth, prospering societies and a healthy environment. No new ethic is required. This so-called weak version of sustainability is popular among governments, and businesses, but profoundly wrong and not even weak, as there is no alternative to preserving the earth's ecological integrity." Society and culture Sustainable development goals Education for sustainable development Education for sustainable development (ESD) is a term officially used by the United Nations. It is defined as education practices that encourage changes in knowledge, skills, values, and attitudes to enable a more sustainable and just society for humanity. ESD aims to empower and equip current and future generations to meet their needs using a balanced and integrated approach to sustainable development's economic, social, and environmental dimensions. Agenda 21 was the first international document that identified education as an essential tool for achieving sustainable development and highlighted areas of action for education. ESD is a component of measurement in an indicator for Sustainable Development Goal 12 (SDG) for "responsible consumption and production". SDG 12 has 11 targets, and target 12.8 is "By 2030, ensure that people everywhere have the relevant information and awareness for sustainable development and lifestyles in harmony with nature." 20 years after the Agenda 21 document was declared, the 'Future we want' document was proclaimed in the Rio+20 UN Conference on Sustainable Development, stating that "We resolve to promote education for sustainable development and to integrate sustainable development more actively into education beyond the Decade of Education for Sustainable Development." One version of education for Sustainable Development recognizes modern-day environmental challenges. It seeks to define new ways to adjust to a changing biosphere, as well as engage individuals to address societal issues that come with them In the International Encyclopedia of Education, this approach to education is seen as an attempt to "shift consciousness toward an ethics of life-giving relationships that respects the interconnectedness of man to his natural world" to equip future members of society with environmental awareness and a sense of responsibility to sustainability. For UNESCO, education for sustainable development involves: The Thessaloniki Declaration, presented at the "International Conference on Environment and Society: Education and Public Awareness for Sustainability" by UNESCO and the Government of Greece (December 1997), highlights the importance of sustainability not only with regards to the natural environment, but also with "poverty, health, food security, democracy, human rights, and peace".

Spiritual ecology

Spiritual ecology is an emerging field in religion, conservation, and academia that proposes that there is a spiritual facet to all issues related to conservation, environmentalism, and earth stewardship. Proponents of spiritual ecology assert a need for contemporary nature conservation work to include spiritual elements and for contemporary religion and spirituality to include awareness of and engagement in ecological issues. Introduction Contributors in the field of spiritual ecology contend there are spiritual elements at the root of environmental issues. Those working in the arena of spiritual ecology further suggest that there is a critical need to recognize and address the spiritual dynamics at the root of environmental degradation. The field is largely emerging through three individual streams of formal study and activity: science and academia, religion and spirituality, and ecological sustainability. Despite the disparate arenas of study and practice, the principles of spiritual ecology are simple: In order to resolve such environmental issues as depletion of species, global warming, and over-consumption, humanity must examine and reassess our underlying attitudes and beliefs about the earth, and our spiritual responsibilities toward the planet. U.S. advisor on climate change, James Gustave Speth, said: Thus, it is argued, ecological renewal and sustainability necessarily depends upon spiritual awareness and an attitude of responsibility. Spiritual ecologists concur that this includes both the recognition of creation as sacred and behaviors that honor that sacredness. Recent written and spoken contributions of Pope Francis, particularly his May 2015 Encyclical, Laudato si', as well as unprecedented involvement of faith leaders at the 2015 United Nations Climate Change Conference in Paris reflect a growing popularity of this emerging view. The UN secretary general, Ban Ki-moon, stated on December 4, 2015, that History Spiritual ecologists have identified the Scientific Revolution—beginning the 16th century, and continuing through the Age of Enlightenment to the Industrial Revolution—as contributing to a critical shift in human understanding with reverberating effects on the environment. The radical expansion of collective consciousness into the era of rational science included a collective change from experiencing nature as a living, spiritual presence to a utilitarian means to an end. During the modern age, reason became valued over faith, tradition, and revelation. Industrialized society replaced agricultural societies and the old ways of relating to seasons and cycles. Furthermore, it is argued that the growing predominance of a global, mechanized and commercialized worldview, a collective sense of the sacred was severed and replaced with an insatiable drive for scientific progress and material prosperity without any sense of limits or responsibility. Some in spiritual ecology argue that a pervasive patriarchal competitive world-view, and a monotheistic religious orientation towards a transcendent divinity, is largely responsible for destructive attitudes about the earth, body, and the sacred nature of creation. Thus, many identify the wisdom of indigenous cultures, for whom the physical world is still regarded as sacred, as holding a key to our current ecological predicament. Spiritual ecology is a response to the values and socio-political structures of recent centuries with their trajectory away from intimacy with the earth and its sacred essence. It has been forming and developing as an intellectual and practice-oriented discipline for nearly a century. Spiritual ecology includes a vast array of people and practices that intertwine spiritual and environmental experience and understanding. Additionally, within the tradition itself resides a deep, developing spiritual vision of a collective human/earth/divine evolution that is expanding consciousness beyond the dualities of human/other, human/earth, heaven/earth, mind/body. This belongs to the contemporary movement that recognizes the unity and interrelationship, or "interbeing", the interconnectedness of all of that is creation. Spiritual visionaries carrying this thread include Rudolf Steiner (1861–1925) who founded the spiritual movement of anthroposophy, and described a "co-evolution of spirituality and nature" and Pierre Teilhard de Chardin (1881–1955), a French Jesuit and paleontologist who spoke of a transition in collective awareness toward a consciousness of the divinity within every particle of life, even the most dense mineral. This shift includes the necessary dissolution of divisions between fields of study as mentioned above. "Science, philosophy and religion are bound to converge as they draw nearer to the whole", said Teilhard. Thomas Berry (1914–2009), the American Passionist priest known a 'geologian', has been one of the most influential figures in this developing movement, with his stress on returning to a sense of wonder and reverence for the natural world. He shared and furthered many of Teilhard de Chardin's views, including the understanding that humanity is not at the center of the universe, but integrated into a divine whole with its own evolutionary path. This view compels a re-thinking of the earth/human relationship: "The present urgency is to begin thinking within the context of the whole planet, the integral earth community with all its human and other-than-human components." Leaders in Buddhism including the Engaged Buddhism movement, historically identify a need to return to a sense ones innate inborn nature that is part of the Earth. Joanna Macy describes a collective shift – referred to as the "Great Turning" – taking humanity into a new consciousness in which the earth is not experienced as separate. Sufi teacher Llewellyn Vaughan-Lee similarly grounds his spiritual ecology work in the context of a collective evolutionary expansion towards oneness, bringing us all toward an experience of earth and humanity – all life – as interdependent. In the vision and experience of oneness, the term "spiritual ecology" becomes, itself, redundant. What is earth-sustaining is spiritual; that which is spiritual honors a sacred earth. An important element in the work of these contemporary teachers is the call for humanity's full acceptance of responsibility for what we have done – physically and spiritually – to the earth. Only through accepting responsibility will healing and transformation occur. Including the need for a spiritual response to the environmental crisis, Charles, Prince of Wales in his 2010 book Harmony: A New Way of Looking at Our World, writes: "A specifically mechanistic science has only recently assumed a position of such authority in the world... (and) not only has it prevented us from considering the world philosophically any more, our predominantly mechanistic way of looking at the world has also excluded our spiritual relationship with Nature. Any such concerns get short shrift in the mainstream debate about what we do to the Earth." Prince Charles, who has promoted environmental awareness since the 1980s, continues: In May 2015 Pope Francis's Encyclical, "Laudato Si': On Care for our Common Home", endorsed the need for a spiritual and moral response to our environmental crisis, and thus implicitly brings the subject of spiritual ecology to the forefront of our present ecological debate. This encyclical recognizes that "The ecological crisis is essentially a spiritual problem", in line with the ideas of this developing field. American environmentalist, author, and journalist Bill McKibben who has written extensively on the impact of global warming, says that Pope Francis has "brought the full weight of the spiritual order to bear on the global threat posed by climate change, and in so doing joined its power with the scientific order". Scientist, environmentalist, and a leader in sustainable ecology David Suzuki also expresses the importance of including the sacred in addressing the ecological crisis: A Catholic nun interviewed by Sarah MacFarland Taylor, author of the 2009 book, Green Sisters: Spiritual Ecology, articulates this perspective of unity: "There is no division between planting new fields and prayer." Indigenous wisdom Many in the field of spiritual ecology agree that a distinct stream of experience threading throughout history that has at its heart a lived understanding of the principles, values and attitudes of spiritual ecology: indigenous wisdom. The term "indigenous" in this context refers to that which is native, original, and resident to a place, more specifically to societies who share and preserve ways of knowing the world in relationship to the land. For many Native traditions, the earth is the central spiritual context. This principle condition reflects an attitude and way of being in the world that is rooted in land and embedded in place. Spiritual ecology directs us to look to revered holders of these traditions in order to understand the source of our current ecological and spiritual crisis and find guidance to move into a state of balance. Features of many indigenous teachings include life as a continual act of prayer and thanksgiving, knowledge and symbiotic relationship with an animate nature, and being aware of one's actions on future generations. Such understanding necessarily implies a mutuality and reciprocity between people, earth and the cosmos. The above historical trajectory is located predominantly in a Judeo-Christian European context, for it is within this context that humanity experienced the loss of the sacred nature of creation, with its devastating consequences. For example, with colonization, indigenous spiritual ecology was historically replaced by an imposed Western belief that land and the environment are commodities to be used and exploited, with exploitation of natural resources in the name of socio-economic evolution. This perspective "... tended to remove any spiritual value of the land, with regard only given for economic value, and this served to further distance communities from intimate relationships with their environments", often with "devastating consequences for indigenous people and nature around the world". Research on early prehistoric human activity in the Quaternary extinction event, shows overhunting megafauna well before European colonization in North America, South America and Australia. While this might cast doubt upon the view of indigenous wisdom and the sacred relationship to land and environment throughout the entirety of human history, it this does not negate the more recent devastating effects as referenced. Along with the basic principles and behaviors advocated by spiritual ecology, some indigenous traditions hold the same evolutionary view articulated by the Western spiritual teachers listed above. The understanding of humanity evolving toward a state of unity and harmony with the earth after a period of discord and suffering is described in a number of prophecies around the globe. These include the White Buffalo prophecy of the Plains Indians, the prophecy of the Eagle and Condor from the people of the Andes, and the Onondaga prophecies held and retold by Oren Lyons. Current trends Spiritual ecology is developing largely in three arenas identified above: science and academia, religion and spirituality, and environmental conservation. Science and academia Among scholars contributing to spiritual ecology, five stand out: Steven Clark Rockefeller, Mary Evelyn Tucker, John Grim, Bron Taylor and Roger S. Gottlieb. Mary Evelyn Tucker and John Grim are the co-ordinators of the Yale Forum on Religion and Ecology, an international multi-religious project exploring religious world-views, texts ethics and practices in order to broaden understanding of the complex nature of current environmental concerns. Steven C. Rockefeller is an author of numerous books about religion and the environment, and is professor emeritus of religion at Middlebury College. He played a leading role in the drafting of the Earth Charter. Roger S. Gottlieb is a professor of Philosophy at Worcester Polytechnic Institute is author of over 100 articles and 16 books on environmentalism, religious life, contemporary spirituality, political philosophy, ethics, feminism, and the Holocaust. Bron Taylor at the University of Florida coined the term "Dark Green Religion" to describe a set of beliefs and practices centered on the conviction that nature is sacred. Other leaders in the field include: Leslie E. Sponsel at the University of Hawaiʻi, Sarah McFarland Taylor at Northwestern University, Mitchell Thomashow at Antioch University New England and the Schumacher College Programs. Within the field of science, spiritual ecology is emerging in arenas including physics, biology (e.g. Ursula Goodenough), consciousness studies (e.g. Brian Swimme at California Institute of Integral Studies), systems theory (e.g. David Loy), and the Gaia hypothesis, which was first articulated by James Lovelock and Lynn Margulis in the 1970s. Another example is scientist and author Diana Beresford-Kroeger, world recognized expert on how trees chemically affect the environment, who brings together the fields of ethnobotany, horticulture, ecology, and spirituality in relation to the current ecological crisis and stewardship of the natural world. She says, "... the world, the gift of this world is fantastic and phenomenal. The molecular working of the world is extraordinary, the mathematics of the world is extraordinary ... sacred and science go together." Religion and ecology Within many faiths, environmentalism is becoming an area of study and advocacy. Pope Francis's May 2015 encyclical, Laudato si', offered a strong confirmation of spiritual ecology and its principles from within the Catholic Church. Additionally, over 150 leaders from various faiths signed a letter to the UN Climate Summit in Paris 2015 recognizing the earth as "a gift" from God and calling for climate action. Christian environmentalists emphasize the ecological responsibilities of all Christians as stewards of God's earth, while contemporary Muslim religious ecology is inspired by Qur'anic themes, such as mankind being khalifa, or trustee of God on earth (2:30). There is also a Jewish ecological perspective based upon the Bible and Torah, for example the laws of bal tashchit (neither to destroy wantonly, nor waste resources unnecessarily). Engaged Buddhism applies Buddhist principles and teachings to social and environmental issues. A collection of Buddhist responses to global warming can be seen at Ecological Buddhism. In addition to Pope Francis, other world traditions currently seem to include a subset of leaders committed to an ecological perspective. The "Green Patriarch" Bartholomew I, the Ecumenical Patriarch of the Eastern Orthodox Church, has worked since the late nineties to bring together scientists, environmentalists, religious leaders and policy makers to address the ecological crisis, and says protecting the planet is a "sacred task and a common vocation ... Global warming is a moral crisis and a moral challenge." The Islamic Foundation For Ecology And Environmental Sciences (IFEES) were one of the sponsors of the International Islamic Climate Change Symposium held in Istanbul in August 2015, which resulted in "The Islamic Declaration on Global Climate Change"—a declaration endorsed by religious leaders, noted Islamic scholars and teachers from 20 countries. In October, 2015, 425 rabbis signed "A Rabbinic Letter on the Climate Crisis", calling for vigorous action to prevent worsening climate disruption and to seek eco-social justice. Hindu scriptures also allude strongly and often to the connection between humans and nature, and these texts form the foundation of the Hindu Declaration on Climate Change, presented at a 2009 meeting of the Parliament of World Religions. Many world faith and religious leaders, such as the 14th Dalai Lama, were present at the 2015 Climate Change Conference, and shared the view that: "Saving the planet is not just a political duty, but also a moral one." The Karmapa, Ogyen Trinley Dorje, has also stated, "The environmental emergency that we face is not just a scientific issue, nor is it just a political issue—it is also a moral issue." These religious approaches to ecology also have a growing interfaith expression, for example in the Interfaith Center for Sustainable Development where world religious leaders speak out on climate change and sustainability. And at their gathering in Fall 2015, the Parliament of World Religions created a declaration for Interfaith Action on Climate Change, and "brought together more than 10,000 activists, professors, clergy, and global leaders from 73 countries and 50 faiths to confront climate change". Earth-based traditions and earth spirituality Care for and respect to earth as sacred—as Mother Earth (Mother Nature)—who provides life and nourishment, is one form of Earth-based spirituality. PaGaian Cosmology is a tradition within such Earth-based spirituality. Glenys Livingstone describes it in her book as Spirituality and ecology While religiously-oriented environmentalism is grounded in scripture and theology, there is a movement that articulates the need for an ecological approach founded on spiritual awareness rather than religious belief. The individuals articulating this approach may have a religious background, but their ecological vision comes from their own lived spiritual experience. The difference between this spiritually-oriented ecology and a religious approach to ecology can be seen as analogous to how the Inter-spiritual Movement moves beyond interfaith and interreligious dialogue to focus on the actual experience of spiritual principles and practices. Spiritual ecology similarly explores the importance of this experiential spiritual dimension in relation to the present ecological crisis. The Engaged Buddhist teacher Thich Nhat Hanh speaks of the importance of mindfulness in taking care of our Mother Earth, and how the highest form of prayer is real communion with the Earth. Franciscan friar Richard Rohr emphasizes the need to experience the whole world as a divine incarnation. Sufi mystic Llewellyn Vaughan-Lee directs our attention not just to the suffering of the physical world, but also its interior spiritual self, or anima mundi (world soul). Cultural ecologist and geophilosopher David Abram, who coined the phrase "the more-than-human world" (in order to describe nature as a realm that thoroughly includes humankind with all our culture yet also necessarily exceeds human creativity and culture) aims the careful language of his writing and speaking toward a reenchantment of matter. He was the first philosopher to call for an attentive reappraisal of "animism" as a uniquely ecological way of perceiving, speaking, and thinking; his writings are now associated with a broad movement, among both academics and environmental activists, often termed the "new animism" Environmental conservation The environmental conservation field has been informed, shaped, and led by individuals who have reported profound experiences of nature's sacredness and have fought to protect it. Robin Wall Kimmerer, Professor of Environmental and Forest Biology at the State University of New York, has founded the Center for Native Peoples and the Environment which bridges scientific based study of ecology and the environment with traditional ecological knowledge, which includes spirituality. As she wrote in BioScience: The World Wide Fund for Nature has developed "Sacred Earth: Faiths for Conservation", a program to collaborate with spiritual leaders and faith communities from all different spiritual traditions around the world, to face environmental issues including deforestation, pollution, unsustainable extraction, melting glaciers and rising sea levels. The Sacred Earth program works with faith-based leaders and communities, who "best articulate ethical and spiritual ideals around the sacred value of Earth and its diversity, and are committed to protecting it". One of the conservation projects developed from the WWF Sacred Earth program is Khoryug, based in the Eastern Himalayas, which is an association of several Tibetan Buddhist monasteries that works on environmental protection of the Himalayan region through apply the values of compassion and interdependence towards the Earth and all living beings that dwell here. Organized under the auspices of the 17th Karmapa, Ogyen Trinley Dorje, the Khoryug project resulted in the publication of environmental guidelines for Buddhists and "more than 55 monastery-led projects to address forest degradation, water loss, wildlife trade, waste, pollution and climate change". Krishna Kant Shukla, a physicist and musician, is noted for his lectures on "Indian villages as models of sustainable development" and his work in establishing Saha Astitva, a model ecovillage and organic farm in tribal Maharashtra, India. Women have shown a unique commitment and capacity to protect the earth's resources, as illustrated by the lives of Wangari Maathai, founder of Africa's Green Belt Movement, which was initially made up of women planting trees; Jane Goodall, innovator of local sustainable programs in Africa, many of which are designed to empower girls and women; and Vandana Shiva, the Indian feminist activist working on a variety of issues including seed saving, protecting small farms in India and protesting agri-business. Other contemporary inter-disciplinary environmentalists include Wendell Berry, a farmer, poet, and academic living in Kentucky, who fights for small farms and criticizes agri-business; and Satish Kumar, a former Jain monk and founder of Schumacher College, a center for ecological studies. Opposing views Although the May 2015 Encyclical from Pope Francis brought the importance of the subject spiritual ecology to the fore of mainstream contemporary culture, it is a point of view that is not widely used in the work of mainstream environmentalists and ecologists. Academic research on the subject has also generated some criticism.<ref>See also Sponsel, Leslie E. Religion, nature and environmentalism Encyclopedia of the Earth, published July 2, 2007 (updated March 2013).</ref> Ken Wilber has criticized spiritual ecology, suggesting that "spiritually oriented deep ecologists" fail to acknowledge the transcendent aspect of the divine, or hierarchical cosmologies, and thus exclude an important aspect of spirituality, as well as presenting what Wilber calls a one-dimensional "flat land" ontology in which the sacred in nature is wholly immanent. But Wilber's views are also criticized as not including an in-depth understanding of indigenous spirituality.

Human behavior

Human behavior is the potential and expressed capacity (mentally, physically, and socially) of human individuals or groups to respond to internal and external stimuli throughout their life. Behavior is driven by genetic and environmental factors that affect an individual. Behavior is also driven, in part, by thoughts and feelings, which provide insight into individual psyche, revealing such things as attitudes and values. Human behavior is shaped by psychological traits, as personality types vary from person to person, producing different actions and behavior. Social behavior accounts for actions directed at others. It is concerned with the considerable influence of social interaction and culture, as well as ethics, interpersonal relationships, politics, and conflict. Some behaviors are common while others are unusual. The acceptability of behavior depends upon social norms and is regulated by various means of social control. Social norms also condition behavior, whereby humans are pressured into following certain rules and displaying certain behaviors that are deemed acceptable or unacceptable depending on the given society or culture. Cognitive behavior accounts for actions of obtaining and using knowledge. It is concerned with how information is learned and passed on, as well as creative application of knowledge and personal beliefs such as religion. Physiological behavior accounts for actions to maintain the body. It is concerned with basic bodily functions as well as measures taken to maintain health. Economic behavior accounts for actions regarding the development, organization, and use of materials as well as other forms of work. Ecological behavior accounts for actions involving the ecosystem. It is concerned with how humans interact with other organisms and how the environment shapes human behavior. Study Human behavior is studied by the social sciences, which include psychology, sociology, ethology, and their various branches and schools of thought. There are many different facets of human behavior, and no one definition or field study encompasses it in its entirety. The nature versus nurture debate is one of the fundamental divisions in the study of human behavior; this debate considers whether behavior is predominantly affected by genetic or environmental factors. The study of human behavior sometimes receives public attention due to its intersection with cultural issues, including crime, sexuality, and social inequality. Some natural sciences also place emphasis on human behavior. Neurology and evolutionary biology, study how behavior is controlled by the nervous system and how the human mind evolved, respectively. In other fields, human behavior may be a secondary subject of study when considering how it affects another subject. Outside of formal scientific inquiry, human behavior and the human condition is also a major focus of philosophy and literature. Philosophy of mind considers aspects such as free will, the mind–body problem, and malleability of human behavior. Human behavior may be evaluated through questionnaires, interviews, and experimental methods. Animal testing may also be used to test behaviors that can then be compared to human behavior. Twin studies are a common method by which human behavior is studied. Twins with identical genomes can be compared to isolate genetic and environmental factors in behavior. Lifestyle, susceptibility to disease, and unhealthy behaviors have been identified to have both genetic and environmental indicators through twin studies. Social behavior Human social behavior is the behavior that considers other humans, including communication and cooperation. It is highly complex and structured, based on advanced theory of mind that allows humans to attribute thoughts and actions to one another. Through social behavior, humans have developed society and culture distinct from other animals. Human social behavior is governed by a combination of biological factors that affect all humans and cultural factors that change depending on upbringing and societal norms. Human communication is based heavily on language, typically through speech or writing. Nonverbal communication and paralanguage can modify the meaning of communications by demonstrating ideas and intent through physical and vocal behaviors. Social norms Human behavior in a society is governed by social norms. Social norms are unwritten expectations that members of society have for one another. These norms are ingrained in the particular culture that they emerge from, and humans often follow them unconsciously or without deliberation. These norms affect every aspect of life in human society, including decorum, social responsibility, property rights, contractual agreement, morality, and justice. Many norms facilitate coordination between members of society and prove mutually beneficial, such as norms regarding communication and agreements. Norms are enforced by social pressure, and individuals that violate social norms risk social exclusion. Systems of ethics are used to guide human behavior to determine what is moral. Humans are distinct from other animals in the use of ethical systems to determine behavior. Ethical behavior is human behavior that takes into consideration how actions will affect others and whether behaviors will be optimal for others. What constitutes ethical behavior is determined by the individual value judgments of the person and the collective social norms regarding right and wrong. Value judgments are intrinsic to people of all cultures, though the specific systems used to evaluate them may vary. These systems may be derived from divine law, natural law, civil authority, reason, or a combination of these and other principles. Altruism is an associated behavior in which humans consider the welfare of others equally or preferentially to their own. While other animals engage in biological altruism, ethical altruism is unique to humans. Deviance is behavior that violates social norms. As social norms vary between individuals and cultures, the nature and severity of a deviant act is subjective. What is considered deviant by a society may also change over time as new social norms are developed. Deviance is punished by other individuals through social stigma, censure, or violence. Many deviant actions are recognized as crimes and punished through a system of criminal justice. Deviant actions may be punished to prevent harm to others, to maintain a particular worldview and way of life, or to enforce principles of morality and decency. Cultures also attribute positive or negative value to certain physical traits, causing individuals that do not have desirable traits to be seen as deviant. Interpersonal relationships Interpersonal relationships can be evaluated by the specific choices and emotions between two individuals, or they can be evaluated by the broader societal context of how such a relationship is expected to function. Relationships are developed through communication, which creates intimacy, expresses emotions, and develops identity. An individual's interpersonal relationships form a social group in which individuals all communicate and socialize with one another, and these social groups are connected by additional relationships. Human social behavior is affected not only by individual relationships, but also by how behaviors in one relationship may affect others. Individuals that actively seek out social interactions are extraverts, and those that do not are introverts. Romantic love is a significant interpersonal attraction toward another. Its nature varies by culture, but it is often contingent on gender, occurring in conjunction with sexual attraction and being either heterosexual or homosexual. It takes different forms and is associated with many individual emotions. Many cultures place a higher emphasis on romantic love than other forms of interpersonal attraction. Marriage is a union between two people, though whether it is associated with romantic love is dependent on the culture. Individuals that are closely related by consanguinity form a family. There are many variations on family structures that may include parents and children as well as stepchildren or extended relatives. Family units with children emphasize parenting, in which parents engage in a high level of parental investment to protect and instruct children as they develop over a period of time longer than that of most other mammals. Politics and conflict When humans make decisions as a group, they engage in politics. Humans have evolved to engage in behaviors of self-interest, but this also includes behaviors that facilitate cooperation rather than conflict in collective settings. Individuals will often form in-group and out-group perceptions, through which individuals cooperate with the in-group and compete with the out-group. This causes behaviors such as unconsciously conforming, passively obeying authority, taking pleasure in the misfortune of opponents, initiating hostility toward out-group members, artificially creating out-groups when none exist, and punishing those that do not comply with the standards of the in-group. These behaviors lead to the creation of political systems that enforce in-group standards and norms. When humans oppose one another, it creates conflict. It may occur when the involved parties have a disagreement of opinion, when one party obstructs the goals of another, or when parties experience negative emotions such as anger toward one another. Conflicts purely of disagreement are often resolved through communication or negotiation, but incorporation of emotional or obstructive aspects can escalate conflict. Interpersonal conflict is that between specific individuals or groups of individuals. Social conflict is that between different social groups or demographics. This form of conflict often takes place when groups in society are marginalized, do not have the resources they desire, wish to instigate social change, or wish to resist social change. Significant social conflict can cause civil disorder. International conflict is that between nations or governments. It may be solved through diplomacy or war. Cognitive behavior Human cognition is distinct from that of other animals. This is derived from biological traits of human cognition, but also from shared knowledge and development passed down culturally. Humans are able to learn from one another due to advanced theory of mind that allows knowledge to be obtained through education. The use of language allows humans to directly pass knowledge to one another. The human brain has neuroplasticity, allowing it to modify its features in response to new experiences. This facilitates learning in humans and leads to behaviors of practice, allowing the development of new skills in individual humans. Behavior carried out over time can be ingrained as a habit, where humans will continue to regularly engage in the behavior without consciously deciding to do so. Humans engage in reason to make inferences with a limited amount of information. Most human reasoning is done automatically without conscious effort on the part of the individual. Reasoning is carried out by making generalizations from past experiences and applying them to new circumstances. Learned knowledge is acquired to make more accurate inferences about the subject. Deductive reasoning infers conclusions that are true based on logical premises, while inductive reasoning infers what conclusions are likely to be true based on context. Emotion is a cognitive experience innate to humans. Basic emotions such as joy, distress, anger, fear, surprise, and disgust are common to all cultures, though social norms regarding the expression of emotion may vary. Other emotions come from higher cognition, such as love, guilt, shame, embarrassment, pride, envy, and jealousy. These emotions develop over time rather than instantly and are more strongly influenced by cultural factors. Emotions are influenced by sensory information, such as color and music, and moods of happiness and sadness. Humans typically maintain a standard level of happiness or sadness determined by health and social relationships, though positive and negative events have short-term influences on mood. Humans often seek to improve the moods of one another through consolation, entertainment, and venting. Humans can also self-regulate mood through exercise and meditation. Creativity is the use of previous ideas or resources to produce something original. It allows for innovation, adaptation to change, learning new information, and novel problem solving. Expression of creativity also supports quality of life. Creativity includes personal creativity, in which a person presents new ideas authentically, but it can also be expanded to social creativity, in which a community or society produces and recognizes ideas collectively. Creativity is applied in typical human life to solve problems as they occur. It also leads humans to carry out art and science. Individuals engaging in advanced creative work typically have specialized knowledge in that field, and humans draw on this knowledge to develop novel ideas. In art, creativity is used to develop new artistic works, such as visual art or music. In science, those with knowledge in a particular scientific field can use trial and error to develop theories that more accurately explain phenomena. Religious behavior is a set of traditions that are followed based on the teachings of a religious belief system. The nature of religious behavior varies depending on the specific religious traditions. Most religious traditions involve variations of telling myths, practicing rituals, making certain things taboo, adopting symbolism, determining morality, experiencing altered states of consciousness, and believing in supernatural beings. Religious behavior is often demanding and has high time, energy, and material costs, and it conflicts with rational choice models of human behavior, though it does provide community-related benefits. Anthropologists offer competing theories as to why humans adopted religious behavior. Religious behavior is heavily influenced by social factors, and group involvement is significant in the development of an individual's religious behavior. Social structures such as religious organizations or family units allow the sharing and coordination of religious behavior. These social connections reinforce the cognitive behaviors associated with religion, encouraging orthodoxy and commitment. According to a Pew Research Center report, 54% of adults around the world state that religion is very important in their lives as of 2018. Physiological behavior Humans undergo many behaviors common to animals to support the processes of the human body. Humans eat food to obtain nutrition. These foods may be chosen for their nutritional value, but they may also be eaten for pleasure. Eating often follows a food preparation process to make it more enjoyable. Humans dispose of waste through urination and defecation. Excrement is often treated as taboo, particularly in developed and urban communities where sanitation is more widely available and excrement has no value as fertilizer. Humans also regularly engage in sleep, based on homeostatic and circadian factors. The circadian rhythm causes humans to require sleep at a regular pattern and is typically calibrated to the day-night cycle and sleep-wake habits. Homeostasis is also maintained, causing longer sleep longer after periods of sleep deprivation. The human sleep cycle takes place over 90 minutes, and it repeats 3–5 times during normal sleep. There are also unique behaviors that humans undergo to maintain physical health. Humans have developed medicine to prevent and treat illnesses. In industrialized nations, eating habits that favor better nutrition, hygienic behaviors that promote sanitation, medical treatment to eradicate diseases, and the use of birth control significantly improve human health. Humans can also engage in exercise beyond that required for survival to maintain health. Humans engage in hygiene to limit exposure to dirt and pathogens. Some of these behaviors are adaptive while others are learned. Basic behaviors of disgust evolved as an adaptation to prevent contact with sources of pathogens, resulting in a biological aversion to feces, body fluids, rotten food, and animals that are commonly disease vectors. Personal grooming, disposal of human corpses, use of sewerage, and use of cleaning agents are hygienic behaviors common to most human societies. Humans reproduce sexually, engaging in sexual intercourse for both reproduction and sexual pleasure. Human reproduction is closely associated with human sexuality and an instinctive desire to procreate, though humans are unique in that they intentionally control the number of offspring that they produce. Humans engage in a large variety of reproductive behaviors relative to other animals, with various mating structures that include forms of monogamy, polygyny, and polyandry. How humans engage in mating behavior is heavily influenced by cultural norms and customs. Unlike most mammals, human women ovulate spontaneously rather than seasonally, with a menstrual cycle that typically lasts 25–35 days. Humans are bipedal and move by walking. Human walking corresponds to the bipedal gait cycle, which involves alternating heel contact and toe off with the ground and slight elevation and rotation of the pelvis. Balance while walking is learned during the first 7–9 years of life, and individual humans develop unique gaits while learning to displace weight, adjust center of mass, and coordinate neural control with movement. Humans can achieve higher speed by running. The endurance running hypothesis proposes that humans can outpace most other animals over long distances through running, though human running causes a higher rate of energy exertion. The human body self-regulates through perspiration during periods of exertion, allowing humans more endurance than other animals. The human hand is prehensile and capable of grasping objects and applying force with control over the hand's dexterity and grip strength. This allows the use of complex tools by humans. Economic behavior Humans engage in predictable behaviors when considering economic decisions, and these behaviors may or may not be rational. Humans make basic decisions through cost–benefit analysis and the acceptable rate of return at the minimum risk. Human economic decision making is often reference dependent, in which options are weighed in reference to the status quo rather than absolute gains and losses. Humans are also loss averse, fearing loss rather than seeking gain. Advanced economic behavior developed in humans after the Neolithic Revolution and the development of agriculture. These developments led to a sustainable supply of resources that allowed specialization in more complex societies. Work The nature of human work is defined by the complexity of society. The simplest societies are tribes that work primarily for sustenance as hunter-gatherers. In this sense, work is not a distinct activity but a constant that makes up all parts of life, as all members of the society must work consistently to stay alive. More advanced societies developed after the Neolithic Revolution, emphasizing work in agricultural and pastoral settings. In these societies, production is increased, ending the need for constant work and allowing some individuals to specialize and work in areas outside of food-production. This also created non-laborious work, as increasing occupational complexity required some individuals to specialize in technical knowledge and administration. Laborious work in these societies has variously been carried out by slaves, serfs, peasants, and guild craftsmen. The nature of work changed significantly during the Industrial Revolution in which the factory system was developed for use by industrializing nations. In addition to further increasing general quality of life, this development changed the dynamic of work. Under the factory system, workers increasingly collaborate with others, employers serve as authority figures during work hours, and forced labor is largely eradicated. Further changes occur in post-industrial societies where technological advance makes industries obsolete, replacing them with mass production and service industries. Humans approach work differently based on both physical and personal attributes, and some work with more effectiveness and commitment than others. Some find work to contribute to personal fulfillment, while others work only out of necessity. Work can also serve as an identity, with individuals identifying themselves based on their occupation. Work motivation is complex, both contributing to and subtracting from various human needs. The primary motivation for work is for material gain, which takes the form of money in modern societies. It may also serve to create self-esteem and personal worth, provide activity, gain respect, and express creativity. Modern work is typically categorized as laborious or blue-collar work and non-laborious or white-collar work. Leisure Leisure is activity or lack of activity that takes place outside of work. It provides relaxation, entertainment, and improved quality of life for individuals. Engaging in leisure can be beneficial for physical and mental health. It may be used to seek temporary relief from psychological stress, to produce positive emotions, or to facilitate social interaction. However, leisure can also facilitate health risks and negative emotions caused by boredom, substance abuse, or high-risk behavior. Leisure may be defined as serious or casual. Serious leisure behaviors involve non-professional pursuit of arts and sciences, the development of hobbies, or career volunteering in an area of expertise. Casual leisure behaviors provide short-term gratification, but they do not provide long-term gratification or personal identity. These include play, relaxation, casual social interaction, volunteering, passive entertainment, active entertainment, and sensory stimulation. Passive entertainment is typically derived from mass media, which may include written works or digital media. Active entertainment involves games in which individuals participate. Sensory stimulation is immediate gratification from behaviors such as eating or sexual intercourse. Consumption Humans operate as consumers that obtain and use goods. All production is ultimately designed for consumption, and consumers adapt their behavior based on the availability of production. Mass consumption began during the Industrial Revolution, caused by the development of new technologies that allowed for increased production. Many factors affect a consumer's decision to purchase goods through trade. They may consider the nature of the product, its associated cost, the convenience of purchase, and the nature of advertising around the product. Cultural factors may influence this decision, as different cultures value different things, and subcultures may have different priorities when it comes to purchasing decisions. Social class, including wealth, education, and occupation may affect one's purchasing behavior. A consumer's interpersonal relationships and reference groups may also influence purchasing behavior. Ecological behavior Like all living things, humans live in ecosystems and interact with other organisms. Human behavior is affected by the environment in which a human lives, and environments are affected by human habitation. Humans have also developed man-made ecosystems such as urban areas and agricultural land. Geography and landscape ecology determine how humans are distributed within an ecosystem, both naturally and through planned urban morphology. Humans exercise control over the animals that live within their environment. Domesticated animals are trained and cared for by humans. Humans can develop social and emotional bonds with animals in their care. Pets are kept for companionship within human homes, including dogs and cats that have been bred for domestication over many centuries. Livestock animals, such as cattle, sheep, goats, and poultry, are kept on agricultural land to produce animal products. Domesticated animals are also kept in laboratories for animal testing. Non-domesticated animals are sometimes kept in nature reserves and zoos for tourism and conservation. Causes and factors Human behavior is influenced by biological and cultural elements. The structure and agency debate considers whether human behavior is predominantly led by individual human impulses or by external structural forces. Behavioral genetics considers how human behavior is affected by inherited traits. Though genes do not guarantee certain behaviors, certain traits can be inherited that make individuals more likely to engage in certain behaviors or express certain personalities. An individual's environment can also affect behavior, often in conjunction with genetic factors. An individual's personality and attitudes affect how behaviors are expressed, formed in conjunction by genetic and environmental factors. Age Infants Infants are limited in their ability to interpret their surroundings shortly after birth. Object permanence and understanding of motion typically develop within the first six months of an infant's life, though the specific cognitive processes are not understood. The ability to mentally categorize different concepts and objects that they perceive also develops within the first year. Infants are quickly able to discern their body from their surroundings and often take interest in their own limbs or actions they cause by two months of age. Infants practice imitation of other individuals to engage socially and learn new behaviors. In young infants, this involves imitating facial expressions, and imitation of tool use takes place within the first year. Communication develops over the first year, and infants begin using gestures to communicate intention around nine to ten months of age. Verbal communication develops more gradually, taking form during the second year of age. Children Children develop fine motor skills shortly after infancy, in the range of three to six years of age, allowing them to engage in behaviors using the hands and eye–hand coordination and perform basic activities of self sufficiency. Children begin expressing more complex emotions in the three- to six-year-old range, including humor, empathy, and altruism, as well engaging in creativity and inquiry. Aggressive behaviors also become varied at this age as children engage in increased physical aggression before learning to favor diplomacy over aggression. Children at this age can express themselves using language with basic grammar. As children grow older, they develop emotional intelligence. Young children engage in basic social behaviors with peers, typically forming friendships centered on play with individuals of the same age and gender. Behaviors of young children are centered around play, which allows them to practice physical, cognitive, and social behaviors. Basic self-concept first develops as children grow, particularly centered around traits such as gender and ethnicity, and behavior is heavily affected by peers for the first time. Adolescents Adolescents undergo changes in behavior caused by puberty and the associated changes in hormone production. Production of testosterone increases sensation seeking and sensitivity to rewards in adolescents as well as aggression and risk-taking in adolescent boys. Production of estradiol causes similar risk-taking behavior among adolescent girls. The new hormones cause changes in emotional processing that allow for close friendships, stronger motivations and intentions, and adolescent sexuality. Adolescents undergo social changes on a large scale, developing a full self-concept and making autonomous decisions independently of adults. They typically become more aware of social norms and social cues than children, causing an increase in self-consciousness and adolescent egocentrism that guides behavior in social settings throughout adolescence. Culture and environment Human brains, as with those of all mammals, are neuroplastic. This means that the structure of the brain changes over time as neural pathways are altered in response to the environment. Many behaviors are learned through interaction with others during early development of the brain. Human behavior is distinct from the behavior of other animals in that it is heavily influenced by culture and language. Social learning allows humans to develop new behaviors by following the example of others. Culture is also the guiding influence that defines social norms. Physiology Neurotransmitters, hormones, and metabolism are all recognized as biological factors in human behavior. Physical disabilities can prevent individuals from engaging in typical human behavior or necessitate alternative behaviors. Accommodations and accessibility are often made available for individuals with physical disabilities in developed nations, including health care, assistive technology, and vocational services. Severe disabilities are associated with increased leisure time but also with a lower satisfaction in the quality of leisure time. Productivity and health both commonly undergo long term decline following the onset of a severe disability. Mental disabilities are those that directly affect cognitive and social behavior. Common mental disorders include mood disorders, anxiety disorders, personality disorders, and substance dependence.

Applied ethics

Applied ethics is the practical aspect of moral considerations. It is ethics with respect to real-world actions and their moral considerations in private and public life, the professions, health, technology, law, and leadership. For example, bioethics is concerned with identifying the best approach to moral issues in the life sciences, such as euthanasia, the allocation of scarce health resources, or the use of human embryos in research. Environmental ethics is concerned with ecological issues such as the responsibility of government and corporations to clean up pollution. Business ethics includes the duties of whistleblowers to the public and to their employers. History Applied ethics has expanded the study of ethics beyond the realms of academic philosophical discourse. The field of applied ethics, as it appears today, emerged from debate surrounding rapid medical and technological advances in the early 1970s and is now established as a subdiscipline of moral philosophy. However, applied ethics is, by its very nature, a multi-professional subject because it requires specialist understanding of the potential ethical issues in fields like medicine, business or information technology. Nowadays, ethical codes of conduct exist in almost every profession. An applied ethics approach to the examination of moral dilemmas can take many different forms but one of the most influential and most widely utilised approaches in bioethics and health care ethics is the four-principle approach developed by Tom Beauchamp and James Childress. The four-principle approach, commonly termed principlism, entails consideration and application of four prima facie ethical principles: autonomy, non-maleficence, beneficence, and justice. Underpinning theory Applied ethics is distinguished from normative ethics, which concerns standards for right and wrong behavior, and from meta-ethics, which concerns the nature of ethical properties, statements, attitudes, and judgments. Whilst these three areas of ethics appear to be distinct, they are also interrelated. The use of an applied ethics approach often draws upon these normative ethical theories: Consequentialist ethics, which hold that the rightness of acts depends only on their consequences. The paradigmatic consequentialist theory is utilitarianism, which classically holds that whether an act is morally right depends on whether it maximizes net aggregated psychological wellbeing. This theory's main developments came from Jeremy Bentham and John Stuart Mill who distinguished between act and rule utilitarianism. Notable later developments were made by Henry Sidgwick who introduced the significance of motive or intent, and R. M. Hare who introduced the significance of preference in utilitarian decision-making. Other forms of consequentialism include prioritarianism. Deontological ethics, which hold that acts have an inherent rightness or wrongness regardless of their context or consequences. This approach is epitomized by Immanuel Kant's notion of the categorical imperative, which was the centre of Kant's ethical theory based on duty. Another key deontological theory is natural law, which was heavily developed by Thomas Aquinas and is an important part of the Catholic Church's teaching on morals. Threshold deontology holds that rules ought to govern up to a point despite adverse consequences; but when the consequences become so dire that they cross a stipulated threshold, consequentialism takes over. Virtue ethics, derived from Aristotle's and Confucius' notions, which asserts that the right action will be that chosen by a suitably 'virtuous' agent. Normative ethical theories can clash when trying to resolve real-world ethical dilemmas. One approach attempting to overcome the divide between consequentialism and deontology is case-based reasoning, also known as casuistry. Casuistry does not begin with theory, rather it starts with the immediate facts of a real and concrete case. While casuistry makes use of ethical theory, it does not view ethical theory as the most important feature of moral reasoning. Casuists, like Albert Jonsen and Stephen Toulmin (The Abuse of Casuistry, 1988), challenge the traditional paradigm of applied ethics. Instead of starting from theory and applying theory to a particular case, casuists start with the particular case itself and then ask what morally significant features (including both theory and practical considerations) ought to be considered for that particular case. In their observations of medical ethics committees, Jonsen and Toulmin note that a consensus on particularly problematic moral cases often emerges when participants focus on the facts of the case, rather than on ideology or theory. Thus, a Rabbi, a Catholic priest, and an agnostic might agree that, in this particular case, the best approach is to withhold extraordinary medical care, while disagreeing on the reasons that support their individual positions. By focusing on cases and not on theory, those engaged in moral debate increase the possibility of agreement. Applied ethics was later distinguished from the nascent applied epistemology, which is also under the umbrella of applied philosophy. While the former was concerned with the practical application of moral considerations, the latter focuses on the application of epistemology in solving practical problems.

Climate change scenario

A climate change scenario is a hypothetical future based on a "set of key driving forces". Scenarios explore the long-term effectiveness of mitigation and adaptation. Scenarios help to understand what the future may hold. They can show which decisions will have the most meaningful effects on mitigation and adaptation. Closely related to climate change scenarios are pathways, which are more concrete and action-oriented. However, in the literature, the terms scenarios and pathways are often used interchangeably. Many parameters influence climate change scenarios. Three important parameters are the number of people (and population growth), their economic activity new technologies. Economic and energy models, such as World3 and POLES, quantify the effects of these parameters. Climate change scenarios exist at a national, regional or global scale. Countries use scenario studies in order to better understand their decisions. This is useful when they are developing their adaptation plans or Nationally Determined Contributions. International goals for mitigating climate change like the Paris Agreement are based on studying these scenarios. For example, the IPCC Special Report on Global Warming of 1.5 °C was a "key scientific input" into the 2018 United Nations Climate Change Conference. Various pathways are considered in the report, describing scenarios for mitigation of global warming. Pathways include for example portfolios for energy supply and carbon dioxide removal. Terminology The IPCC Sixth Assessment Report defines scenario as follows: "A plausible description of how the future may develop based on a [...] set of assumptions about key driving forces and relationships." A set of scenarios shows a range of possible futures. Scenarios are not predictions. Scenarios help decision makers to understand what will be the effects of a decision. The concept of pathways is closely related. The formal definition of pathways is as follows: "The temporal evolution of natural and/or human systems towards a future state. [...] Pathway approaches [...] involve various dynamics, goals, and actors across different scales." In other words: pathways are a roadmap which list actions that need to be taken to make a scenario come true. Decision makers can use a pathway to make a plan, e.g. with regards to the timing of fossil-fuel phase out or the reduction of fossil fuel subsidies. Pathways are more concrete and action-oriented compared to scenarios. They provide a roadmap for achieving desired climate targets. There can be several pathways to achieve the same scenario end point in future. In the literature the terms scenarios and pathways are often used interchangeably. The IPCC publications on the physical science basis tend to use scenarios more, whereas the publications on mitigation tend to use modelled emission and mitigation pathways as a term. Types There are the following types of scenarios: baseline scenarios concentrations scenarios emissions scenarios mitigation scenarios reference scenarios socio economic scenarios. A baseline scenario is used as a reference for comparison against an alternative scenario, e.g., a mitigation scenario. A wide range of quantitative projections of greenhouse gas emissions have been produced. The "SRES" scenarios are "baseline" emissions scenarios (i.e., they assume that no future efforts are made to limit emissions), and have been frequently used in the scientific literature (see Special Report on Emissions Scenarios for details). Purpose Climate change scenarios can be thought of as stories of possible futures. They allow the description of factors that are difficult to quantify, such as governance, social structures, and institutions. There is considerable variety among scenarios, ranging from variants of sustainable development, to the collapse of social, economic, and environmental systems. Factors affecting future GHG emissions The following parameters influence what the scenarios look like: future population levels, economic activity, the structure of governance, social values, and patterns of technological change. No strong patterns were found in the relationship between economic activity and GHG emissions. Economic growth was found to be compatible with increasing or decreasing GHG emissions. In the latter case, emissions growth is mediated by increased energy efficiency, shifts to non-fossil energy sources, and/or shifts to a post-industrial (service-based) economy. Factors affecting the emission projections include: Population projections: All other factors being equal, lower population projections result in lower emissions projections. Economic development: Economic activity is a dominant driver of energy demand and thus of GHG emissions. Energy use: Future changes in energy systems are a fundamental determinant of future GHG emissions. Energy intensity: This is the total primary energy supply (TPES) per unit of GDP. In all of the baseline scenarios assessments, energy intensity was projected to improve significantly over the 21st century. The uncertainty range in projected energy intensity was large. Carbon intensity: This is the CO2 emissions per unit of TPES. Compared with other scenarios, Fisher et al. (2007) found that the carbon intensity was more constant in scenarios where no climate policy had been assumed. The uncertainty range in projected carbon intensity was large. At the high end of the range, some scenarios contained the projection that energy technologies without CO2 emissions would become competitive without climate policy. These projections were based on the assumption of increasing fossil fuel prices and rapid technological progress in carbon-free technologies. Scenarios with a low improvement in carbon intensity coincided with scenarios that had a large fossil fuel base, less resistance to coal consumption, or lower technology development rates for fossil-free technologies. Land-use change: Land-use change plays an important role in climate change, impacting on emissions, sequestration and albedo. One of the dominant drivers in land-use change is food demand. Population and economic growth are the most significant drivers of food demand. In producing scenarios, an important consideration is how social and economic development will progress in developing countries. If, for example, developing countries were to follow a development pathway similar to the current industrialized countries, it could lead to a very large increase in emissions. Emissions do not only depend on the growth rate of the economy. Other factors include the structural changes in the production system, technological patterns in sectors such as energy, geographical distribution of human settlements and urban structures (this affects, for example, transportation requirements), consumption patterns (e.g., housing patterns, leisure activities, etc.), and trade patterns the degree of protectionism and the creation of regional trading blocks can affect availability to technology. In the majority of studies, the following relationships were found (but are not proof of causation): Rising GHGs: This was associated with scenarios having a growing, post-industrial economy with globalization, mostly with low government intervention and generally high levels of competition. Income equality declined within nations, but there was no clear pattern in social equity or international income equality. Falling GHGs: In some of these scenarios, GDP rose. Other scenarios showed economic activity limited at an ecologically sustainable level. Scenarios with falling emissions had a high level of government intervention in the economy. The majority of scenarios showed increased social equity and income equality within and among nations. Predicted trends for greenhouse gas emissions are shown in different formats: Needed emissions cuts Pledges Recent and currently remaining carbon budget Mitigation scenarios Climate change mitigation scenarios are possible futures in which global warming is reduced by deliberate actions, such as a comprehensive switch to energy sources other than fossil fuels. These are actions that minimize emissions so atmospheric greenhouse gas concentrations are stabilized at levels that restrict the adverse consequences of climate change. Using these scenarios, the examination of the impacts of different carbon prices on an economy is enabled within the framework of different levels of global aspirations. The Paris Agreement has the goal to keep the increase of global temperature below 2°C, preferably below 1.5°C above pre-industrial levels to reduce effects of climate change. A typical mitigation scenario is constructed by selecting a long-range target, such as a desired atmospheric concentration of carbon dioxide, and then fitting the actions to the target, for example by placing a cap on net global and national emissions of greenhouse gases. Concentration scenarios Contributions to climate change, whether they cool or warm the Earth, are often described in terms of the radiative forcing or imbalance they introduce to the planet's energy budget. Now and in the future, anthropogenic carbon dioxide is believed to be the major component of this forcing, and the contribution of other components is often quantified in terms of "parts-per-million carbon dioxide equivalent" (ppm CO2e), or the increment/decrement in carbon dioxide concentrations which would create a radiative forcing of the same magnitude. 450 ppm The BLUE scenarios in the IEA's Energy Technology Perspectives publication of 2008 describe pathways to a long-range concentration of 450 ppm. Joseph Romm has sketched how to achieve this target through the application of 14 wedges. World Energy Outlook 2008, mentioned above, also describes a "450 Policy Scenario", in which extra energy investments to 2030 amount to $9.3 trillion over the Reference Scenario. The scenario also features, after 2020, the participation of major economies such as China and India in a global cap-and-trade scheme initially operating in OECD and European Union countries. Also the less conservative 450 ppm scenario calls for extensive deployment of negative emissions, i.e. the removal of from the atmosphere. According to the International Energy Agency (IEA) and OECD, "Achieving lower concentration targets (450 ppm) depends significantly on the use of BECCS". 550 ppm This is the target advocated (as an upper bound) in the Stern Review. As approximately a doubling of levels relative to preindustrial times, it implies a temperature increase of about three degrees, according to conventional estimates of climate sensitivity. Pacala and Socolow list 15 "wedges", any 7 of which in combination should suffice to keep levels below 550 ppm. The International Energy Agency's World Energy Outlook report for 2008 describes a "Reference Scenario" for the world's energy future "which assumes no new government policies beyond those already adopted by mid-2008", and then a "550 Policy Scenario" in which further policies are adopted, a mixture of "cap-and-trade systems, sectoral agreements and national measures". In the Reference Scenario, between 2006 and 2030 the world invests $26.3 trillion in energy-supply infrastructure; in the 550 Policy Scenario, a further $4.1 trillion is spent in this period, mostly on efficiency increases which deliver fuel cost savings of over $7 trillion. Commonly used pathway descriptions Closely related to climate change scenarios are pathways, which are more concrete and action-oriented. The IPCC assessment reports talk about the following types of pathways: 1.5°C pathway Adaptation pathways Climate-resilient pathways Development pathways Emission pathways Mitigation pathways Non-overshoot pathways Overshoot pathways Representative Concentration Pathways (RCPs) Shared Socio-economic Pathways (SSPs) Transformation pathways Representative Concentration Pathway Shared Socioeconomic Pathways National climate (change) projections To explore a wide range of plausible climatic outcomes and to enhance confidence in the projections, national climate change projections are often generated from multiple general circulation models (GCMs). Such climate ensembles can take the form of perturbed physics ensembles (PPE), multi-model ensembles (MME), or initial condition ensembles (ICE). As the spatial resolution of the underlying GCMs is typically quite coarse, the projections are often downscaled, either dynamically using regional climate models (RCMs), or statistically. Some projections include data from areas which are larger than the national boundaries, e.g. to more fully evaluate catchment areas of transboundary rivers. Various countries have produced their national climate projections with feedback and/or interaction with stakeholders. Such engagement efforts have helped tailoring the climate information to the stakeholders' needs, including the provision of sector-specific climate indicators such as degree-heating days. Over 30 countries have reported national climate projections / scenarios in their most recent submissions to the United Nations Framework Convention on Climate Change. Many European governments have also funded national information portals on climate change. Australia: CCIA California: Cal-Adapt Netherlands: KNMI'14 Switzerland: CH2011 / CH2018 UK: UKCP09 / UKCP18 For countries which lack adequate resources to develop their own climate change projections, organisations such as UNDP or FAO have sponsored development of projections and national adaptation programmes (NAPAs).

Ecosystem

An ecosystem (or ecological system) is a system that environments and their organisms form through their interaction. The biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. Internal factors are controlled, for example, by decomposition, root competition, shading, disturbance, succession, and the types of species present. While the resource inputs are generally controlled by external processes, the availability of these resources within the ecosystem is controlled by internal factors. Therefore, internal factors not only control ecosystem processes but are also controlled by them. Ecosystems are dynamic entities—they are subject to periodic disturbances and are always in the process of recovering from some past disturbance. The tendency of an ecosystem to remain close to its equilibrium state, despite that disturbance, is termed its resistance. The capacity of a system to absorb disturbance and reorganize while undergoing change so as to retain essentially the same function, structure, identity, and feedbacks is termed its ecological resilience. Ecosystems can be studied through a variety of approaches—theoretical studies, studies monitoring specific ecosystems over long periods of time, those that look at differences between ecosystems to elucidate how they work and direct manipulative experimentation. Biomes are general classes or categories of ecosystems. However, there is no clear distinction between biomes and ecosystems. Ecosystem classifications are specific kinds of ecological classifications that consider all four elements of the definition of ecosystems: a biotic component, an abiotic complex, the interactions between and within them, and the physical space they occupy. Biotic factors of the ecosystem are living things; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere. Plants allow energy to enter the system through photosynthesis, building up plant tissue. Animals play an important role in the movement of matter and energy through the system, by feeding on plants and on one another. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems provide a variety of goods and services upon which people depend, and may be part of. Ecosystem goods include the "tangible, material products" of ecosystem processes such as water, food, fuel, construction material, and medicinal plants. Ecosystem services, on the other hand, are generally "improvements in the condition or location of things of value". These include things like the maintenance of hydrological cycles, cleaning air and water, the maintenance of oxygen in the atmosphere, crop pollination and even things like beauty, inspiration and opportunities for research. Many ecosystems become degraded through human impacts, such as soil loss, air and water pollution, habitat fragmentation, water diversion, fire suppression, and introduced species and invasive species. These threats can lead to abrupt transformation of the ecosystem or to gradual disruption of biotic processes and degradation of abiotic conditions of the ecosystem. Once the original ecosystem has lost its defining features, it is considered "collapsed". Ecosystem restoration can contribute to achieving the Sustainable Development Goals. Definition An ecosystem (or ecological system) consists of all the organisms and the abiotic pools (or physical environment) with which they interact. The biotic and abiotic components are linked together through nutrient cycles and energy flows. "Ecosystem processes" are the transfers of energy and materials from one pool to another. Ecosystem processes are known to "take place at a wide range of scales". Therefore, the correct scale of study depends on the question asked. Origin and development of the term The term "ecosystem" was first used in 1935 in a publication by British ecologist Arthur Tansley. The term was coined by Arthur Roy Clapham, who came up with the word at Tansley's request. Tansley devised the concept to draw attention to the importance of transfers of materials between organisms and their environment. He later refined the term, describing it as "The whole system, ... including not only the organism-complex, but also the whole complex of physical factors forming what we call the environment". Tansley regarded ecosystems not simply as natural units, but as "mental isolates". Tansley later defined the spatial extent of ecosystems using the term "ecotope". G. Evelyn Hutchinson, a limnologist who was a contemporary of Tansley's, combined Charles Elton's ideas about trophic ecology with those of Russian geochemist Vladimir Vernadsky. As a result, he suggested that mineral nutrient availability in a lake limited algal production. This would, in turn, limit the abundance of animals that feed on algae. Raymond Lindeman took these ideas further to suggest that the flow of energy through a lake was the primary driver of the ecosystem. Hutchinson's students, brothers Howard T. Odum and Eugene P. Odum, further developed a "systems approach" to the study of ecosystems. This allowed them to study the flow of energy and material through ecological systems. Processes External and internal factors Ecosystems are controlled by both external and internal factors. External factors, also called state factors, control the overall structure of an ecosystem and the way things work within it, but are not themselves influenced by the ecosystem. On broad geographic scales, climate is the factor that "most strongly determines ecosystem processes and structure". Climate determines the biome in which the ecosystem is embedded. Rainfall patterns and seasonal temperatures influence photosynthesis and thereby determine the amount of energy available to the ecosystem. Parent material determines the nature of the soil in an ecosystem, and influences the supply of mineral nutrients. Topography also controls ecosystem processes by affecting things like microclimate, soil development and the movement of water through a system. For example, ecosystems can be quite different if situated in a small depression on the landscape, versus one present on an adjacent steep hillside. Other external factors that play an important role in ecosystem functioning include time and potential biota, the organisms that are present in a region and could potentially occupy a particular site. Ecosystems in similar environments that are located in different parts of the world can end up doing things very differently simply because they have different pools of species present. The introduction of non-native species can cause substantial shifts in ecosystem function. Unlike external factors, internal factors in ecosystems not only control ecosystem processes but are also controlled by them. While the resource inputs are generally controlled by external processes like climate and parent material, the availability of these resources within the ecosystem is controlled by internal factors like decomposition, root competition or shading. Other factors like disturbance, succession or the types of species present are also internal factors. Primary production Primary production is the production of organic matter from inorganic carbon sources. This mainly occurs through photosynthesis. The energy incorporated through this process supports life on earth, while the carbon makes up much of the organic matter in living and dead biomass, soil carbon and fossil fuels. It also drives the carbon cycle, which influences global climate via the greenhouse effect. Through the process of photosynthesis, plants capture energy from light and use it to combine carbon dioxide and water to produce carbohydrates and oxygen. The photosynthesis carried out by all the plants in an ecosystem is called the gross primary production (GPP). About half of the gross GPP is respired by plants in order to provide the energy that supports their growth and maintenance. The remainder, that portion of GPP that is not used up by respiration, is known as the net primary production (NPP). Total photosynthesis is limited by a range of environmental factors. These include the amount of light available, the amount of leaf area a plant has to capture light (shading by other plants is a major limitation of photosynthesis), the rate at which carbon dioxide can be supplied to the chloroplasts to support photosynthesis, the availability of water, and the availability of suitable temperatures for carrying out photosynthesis. Energy flow Energy and carbon enter ecosystems through photosynthesis, are incorporated into living tissue, transferred to other organisms that feed on the living and dead plant matter, and eventually released through respiration. The carbon and energy incorporated into plant tissues (net primary production) is either consumed by animals while the plant is alive, or it remains uneaten when the plant tissue dies and becomes detritus. In terrestrial ecosystems, the vast majority of the net primary production ends up being broken down by decomposers. The remainder is consumed by animals while still alive and enters the plant-based trophic system. After plants and animals die, the organic matter contained in them enters the detritus-based trophic system. Ecosystem respiration is the sum of respiration by all living organisms (plants, animals, and decomposers) in the ecosystem. Net ecosystem production is the difference between gross primary production (GPP) and ecosystem respiration. In the absence of disturbance, net ecosystem production is equivalent to the net carbon accumulation in the ecosystem. Energy can also be released from an ecosystem through disturbances such as wildfire or transferred to other ecosystems (e.g., from a forest to a stream to a lake) by erosion. In aquatic systems, the proportion of plant biomass that gets consumed by herbivores is much higher than in terrestrial systems. In trophic systems, photosynthetic organisms are the primary producers. The organisms that consume their tissues are called primary consumers or secondary producers—herbivores. Organisms which feed on microbes (bacteria and fungi) are termed microbivores. Animals that feed on primary consumers—carnivores—are secondary consumers. Each of these constitutes a trophic level. The sequence of consumption—from plant to herbivore, to carnivore—forms a food chain. Real systems are much more complex than this—organisms will generally feed on more than one form of food, and may feed at more than one trophic level. Carnivores may capture some prey that is part of a plant-based trophic system and others that are part of a detritus-based trophic system (a bird that feeds both on herbivorous grasshoppers and earthworms, which consume detritus). Real systems, with all these complexities, form food webs rather than food chains which present a number of common, non random properties in the topology of their network. Decomposition The carbon and nutrients in dead organic matter are broken down by a group of processes known as decomposition. This releases nutrients that can then be re-used for plant and microbial production and returns carbon dioxide to the atmosphere (or water) where it can be used for photosynthesis. In the absence of decomposition, the dead organic matter would accumulate in an ecosystem, and nutrients and atmospheric carbon dioxide would be depleted. Decomposition processes can be separated into three categories—leaching, fragmentation and chemical alteration of dead material. As water moves through dead organic matter, it dissolves and carries with it the water-soluble components. These are then taken up by organisms in the soil, react with mineral soil, or are transported beyond the confines of the ecosystem (and are considered lost to it). Newly shed leaves and newly dead animals have high concentrations of water-soluble components and include sugars, amino acids and mineral nutrients. Leaching is more important in wet environments and less important in dry ones. Fragmentation processes break organic material into smaller pieces, exposing new surfaces for colonization by microbes. Freshly shed leaf litter may be inaccessible due to an outer layer of cuticle or bark, and cell contents are protected by a cell wall. Newly dead animals may be covered by an exoskeleton. Fragmentation processes, which break through these protective layers, accelerate the rate of microbial decomposition. Animals fragment detritus as they hunt for food, as does passage through the gut. Freeze-thaw cycles and cycles of wetting and drying also fragment dead material. The chemical alteration of the dead organic matter is primarily achieved through bacterial and fungal action. Fungal hyphae produce enzymes that can break through the tough outer structures surrounding dead plant material. They also produce enzymes that break down lignin, which allows them access to both cell contents and the nitrogen in the lignin. Fungi can transfer carbon and nitrogen through their hyphal networks and thus, unlike bacteria, are not dependent solely on locally available resources. Decomposition rates Decomposition rates vary among ecosystems. The rate of decomposition is governed by three sets of factors—the physical environment (temperature, moisture, and soil properties), the quantity and quality of the dead material available to decomposers, and the nature of the microbial community itself. Temperature controls the rate of microbial respiration; the higher the temperature, the faster the microbial decomposition occurs. Temperature also affects soil moisture, which affects decomposition. Freeze-thaw cycles also affect decomposition—freezing temperatures kill soil microorganisms, which allows leaching to play a more important role in moving nutrients around. This can be especially important as the soil thaws in the spring, creating a pulse of nutrients that become available. Decomposition rates are low under very wet or very dry conditions. Decomposition rates are highest in wet, moist conditions with adequate levels of oxygen. Wet soils tend to become deficient in oxygen (this is especially true in wetlands), which slows microbial growth. In dry soils, decomposition slows as well, but bacteria continue to grow (albeit at a slower rate) even after soils become too dry to support plant growth. Dynamics and resilience Ecosystems are dynamic entities. They are subject to periodic disturbances and are always in the process of recovering from past disturbances. When a perturbation occurs, an ecosystem responds by moving away from its initial state. The tendency of an ecosystem to remain close to its equilibrium state, despite that disturbance, is termed its resistance. The capacity of a system to absorb disturbance and reorganize while undergoing change so as to retain essentially the same function, structure, identity, and feedbacks is termed its ecological resilience. Resilience thinking also includes humanity as an integral part of the biosphere where we are dependent on ecosystem services for our survival and must build and maintain their natural capacities to withstand shocks and disturbances. Time plays a central role over a wide range, for example, in the slow development of soil from bare rock and the faster recovery of a community from disturbance. Disturbance also plays an important role in ecological processes. F. Stuart Chapin and coauthors define disturbance as "a relatively discrete event in time that removes plant biomass". This can range from herbivore outbreaks, treefalls, fires, hurricanes, floods, glacial advances, to volcanic eruptions. Such disturbances can cause large changes in plant, animal and microbe populations, as well as soil organic matter content. Disturbance is followed by succession, a "directional change in ecosystem structure and functioning resulting from biotically driven changes in resource supply." The frequency and severity of disturbance determine the way it affects ecosystem function. A major disturbance like a volcanic eruption or glacial advance and retreat leave behind soils that lack plants, animals or organic matter. Ecosystems that experience such disturbances undergo primary succession. A less severe disturbance like forest fires, hurricanes or cultivation result in secondary succession and a faster recovery. More severe and more frequent disturbance result in longer recovery times. From one year to another, ecosystems experience variation in their biotic and abiotic environments. A drought, a colder than usual winter, and a pest outbreak all are short-term variability in environmental conditions. Animal populations vary from year to year, building up during resource-rich periods and crashing as they overshoot their food supply. Longer-term changes also shape ecosystem processes. For example, the forests of eastern North America still show legacies of cultivation which ceased in 1850 when large areas were reverted to forests. Another example is the methane production in eastern Siberian lakes that is controlled by organic matter which accumulated during the Pleistocene. Nutrient cycling Ecosystems continually exchange energy and carbon with the wider environment. Mineral nutrients, on the other hand, are mostly cycled back and forth between plants, animals, microbes and the soil. Most nitrogen enters ecosystems through biological nitrogen fixation, is deposited through precipitation, dust, gases or is applied as fertilizer. Most terrestrial ecosystems are nitrogen-limited in the short term making nitrogen cycling an important control on ecosystem production. Over the long term, phosphorus availability can also be critical. Macronutrients which are required by all plants in large quantities include the primary nutrients (which are most limiting as they are used in largest amounts): Nitrogen, phosphorus, potassium. Secondary major nutrients (less often limiting) include: Calcium, magnesium, sulfur. Micronutrients required by all plants in small quantities include boron, chloride, copper, iron, manganese, molybdenum, zinc. Finally, there are also beneficial nutrients which may be required by certain plants or by plants under specific environmental conditions: aluminum, cobalt, iodine, nickel, selenium, silicon, sodium, vanadium. Until modern times, nitrogen fixation was the major source of nitrogen for ecosystems. Nitrogen-fixing bacteria either live symbiotically with plants or live freely in the soil. The energetic cost is high for plants that support nitrogen-fixing symbionts—as much as 25% of gross primary production when measured in controlled conditions. Many members of the legume plant family support nitrogen-fixing symbionts. Some cyanobacteria are also capable of nitrogen fixation. These are phototrophs, which carry out photosynthesis. Like other nitrogen-fixing bacteria, they can either be free-living or have symbiotic relationships with plants. Other sources of nitrogen include acid deposition produced through the combustion of fossil fuels, ammonia gas which evaporates from agricultural fields which have had fertilizers applied to them, and dust. Anthropogenic nitrogen inputs account for about 80% of all nitrogen fluxes in ecosystems. When plant tissues are shed or are eaten, the nitrogen in those tissues becomes available to animals and microbes. Microbial decomposition releases nitrogen compounds from dead organic matter in the soil, where plants, fungi, and bacteria compete for it. Some soil bacteria use organic nitrogen-containing compounds as a source of carbon, and release ammonium ions into the soil. This process is known as nitrogen mineralization. Others convert ammonium to nitrite and nitrate ions, a process known as nitrification. Nitric oxide and nitrous oxide are also produced during nitrification. Under nitrogen-rich and oxygen-poor conditions, nitrates and nitrites are converted to nitrogen gas, a process known as denitrification. Mycorrhizal fungi which are symbiotic with plant roots, use carbohydrates supplied by the plants and in return transfer phosphorus and nitrogen compounds back to the plant roots. This is an important pathway of organic nitrogen transfer from dead organic matter to plants. This mechanism may contribute to more than 70 Tg of annually assimilated plant nitrogen, thereby playing a critical role in global nutrient cycling and ecosystem function. Phosphorus enters ecosystems through weathering. As ecosystems age this supply diminishes, making phosphorus-limitation more common in older landscapes (especially in the tropics). Calcium and sulfur are also produced by weathering, but acid deposition is an important source of sulfur in many ecosystems. Although magnesium and manganese are produced by weathering, exchanges between soil organic matter and living cells account for a significant portion of ecosystem fluxes. Potassium is primarily cycled between living cells and soil organic matter. Function and biodiversity Biodiversity plays an important role in ecosystem functioning. Ecosystem processes are driven by the species in an ecosystem, the nature of the individual species, and the relative abundance of organisms among these species. Ecosystem processes are the net effect of the actions of individual organisms as they interact with their environment. Ecological theory suggests that in order to coexist, species must have some level of limiting similarity—they must be different from one another in some fundamental way, otherwise, one species would competitively exclude the other. Despite this, the cumulative effect of additional species in an ecosystem is not linear: additional species may enhance nitrogen retention, for example. However, beyond some level of species richness, additional species may have little additive effect unless they differ substantially from species already present. This is the case for example for exotic species. The addition (or loss) of species that are ecologically similar to those already present in an ecosystem tends to only have a small effect on ecosystem function. Ecologically distinct species, on the other hand, have a much larger effect. Similarly, dominant species have a large effect on ecosystem function, while rare species tend to have a small effect. Keystone species tend to have an effect on ecosystem function that is disproportionate to their abundance in an ecosystem. An ecosystem engineer is any organism that creates, significantly modifies, maintains or destroys a habitat. Study approaches Ecosystem ecology Ecosystem ecology is the "study of the interactions between organisms and their environment as an integrated system". The size of ecosystems can range up to ten orders of magnitude, from the surface layers of rocks to the surface of the planet. The Hubbard Brook Ecosystem Study started in 1963 to study the White Mountains in New Hampshire. It was the first successful attempt to study an entire watershed as an ecosystem. The study used stream chemistry as a means of monitoring ecosystem properties, and developed a detailed biogeochemical model of the ecosystem. Long-term research at the site led to the discovery of acid rain in North America in 1972. Researchers documented the depletion of soil cations (especially calcium) over the next several decades. Ecosystems can be studied through a variety of approaches—theoretical studies, studies monitoring specific ecosystems over long periods of time, those that look at differences between ecosystems to elucidate how they work and direct manipulative experimentation. Studies can be carried out at a variety of scales, ranging from whole-ecosystem studies to studying microcosms or mesocosms (simplified representations of ecosystems). American ecologist Stephen R. Carpenter has argued that microcosm experiments can be "irrelevant and diversionary" if they are not carried out in conjunction with field studies done at the ecosystem scale. In such cases, microcosm experiments may fail to accurately predict ecosystem-level dynamics. Classifications Biomes are general classes or categories of ecosystems. However, there is no clear distinction between biomes and ecosystems. Biomes are always defined at a very general level. Ecosystems can be described at levels that range from very general (in which case the names are sometimes the same as those of biomes) to very specific, such as "wet coastal needle-leafed forests". Biomes vary due to global variations in climate. Biomes are often defined by their structure: at a general level, for example, tropical forests, temperate grasslands, and arctic tundra. There can be any degree of subcategories among ecosystem types that comprise a biome, e.g., needle-leafed boreal forests or wet tropical forests. Although ecosystems are most commonly categorized by their structure and geography, there are also other ways to categorize and classify ecosystems such as by their level of human impact (see anthropogenic biome), or by their integration with social processes or technological processes or their novelty (e.g. novel ecosystem). Each of these taxonomies of ecosystems tends to emphasize different structural or functional properties. None of these is the "best" classification. Ecosystem classifications are specific kinds of ecological classifications that consider all four elements of the definition of ecosystems: a biotic component, an abiotic complex, the interactions between and within them, and the physical space they occupy. Different approaches to ecological classifications have been developed in terrestrial, freshwater and marine disciplines, and a function-based typology has been proposed to leverage the strengths of these different approaches into a unified system. Human interactions with ecosystems Human activities are important in almost all ecosystems. Although humans exist and operate within ecosystems, their cumulative effects are large enough to influence external factors like climate. Ecosystem goods and services Ecosystems provide a variety of goods and services upon which people depend. Ecosystem goods include the "tangible, material products" of ecosystem processes such as water, food, fuel, construction material, and medicinal plants. They also include less tangible items like tourism and recreation, and genes from wild plants and animals that can be used to improve domestic species. Ecosystem services, on the other hand, are generally "improvements in the condition or location of things of value". These include things like the maintenance of hydrological cycles, cleaning air and water, the maintenance of oxygen in the atmosphere, crop pollination and even things like beauty, inspiration and opportunities for research. While material from the ecosystem had traditionally been recognized as being the basis for things of economic value, ecosystem services tend to be taken for granted. The Millennium Ecosystem Assessment is an international synthesis by over 1000 of the world's leading biological scientists that analyzes the state of the Earth's ecosystems and provides summaries and guidelines for decision-makers. The report identified four major categories of ecosystem services: provisioning, regulating, cultural and supporting services. It concludes that human activity is having a significant and escalating impact on the biodiversity of the world ecosystems, reducing both their resilience and biocapacity. The report refers to natural systems as humanity's "life-support system", providing essential ecosystem services. The assessment measures 24 ecosystem services and concludes that only four have shown improvement over the last 50 years, 15 are in serious decline, and five are in a precarious condition. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is an intergovernmental organization established to improve the interface between science and policy on issues of biodiversity and ecosystem services. It is intended to serve a similar role to the Intergovernmental Panel on Climate Change. Ecosystem services are limited and also threatened by human activities. To help inform decision-makers, many ecosystem services are being assigned economic values, often based on the cost of replacement with anthropogenic alternatives. The ongoing challenge of prescribing economic value to nature, for example through biodiversity banking, is prompting transdisciplinary shifts in how we recognize and manage the environment, social responsibility, business opportunities, and our future as a species. Degradation and decline As human population and per capita consumption grow, so do the resource demands imposed on ecosystems and the effects of the human ecological footprint. Natural resources are vulnerable and limited. The environmental impacts of anthropogenic actions are becoming more apparent. Problems for all ecosystems include: environmental pollution, climate change and biodiversity loss. For terrestrial ecosystems further threats include air pollution, soil degradation, and deforestation. For aquatic ecosystems threats also include unsustainable exploitation of marine resources (for example overfishing), marine pollution, microplastics pollution, the effects of climate change on oceans (e.g. warming and acidification), and building on coastal areas. Many ecosystems become degraded through human impacts, such as soil loss, air and water pollution, habitat fragmentation, water diversion, fire suppression, and introduced species and invasive species. These threats can lead to abrupt transformation of the ecosystem or to gradual disruption of biotic processes and degradation of abiotic conditions of the ecosystem. Once the original ecosystem has lost its defining features, it is considered collapsed (see also IUCN Red List of Ecosystems). Ecosystem collapse could be reversible and in this way differs from species extinction. Quantitative assessments of the risk of collapse are used as measures of conservation status and trends. Management When natural resource management is applied to whole ecosystems, rather than single species, it is termed ecosystem management. Although definitions of ecosystem management abound, there is a common set of principles which underlie these definitions: A fundamental principle is the long-term sustainability of the production of goods and services by the ecosystem; "intergenerational sustainability [is] a precondition for management, not an afterthought". While ecosystem management can be used as part of a plan for wilderness conservation, it can also be used in intensively managed ecosystems (see, for example, agroecosystem and close to nature forestry). Restoration and sustainable development Integrated conservation and development projects (ICDPs) aim to address conservation and human livelihood (sustainable development) concerns in developing countries together, rather than separately as was often done in the past.

Ecosystem diversity

Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment. Ecosystem diversity addresses the combined characteristics of biotic properties which are living organisms (biodiversity) and abiotic properties such as nonliving things like water or soil (geodiversity). It is a variation in the ecosystems found in a region or the variation in ecosystems over the whole planet. Ecological diversity includes the variation in both terrestrial and aquatic ecosystems. Ecological diversity can also take into account the variation in the complexity of a biological community, including the number of different niches, the number of and other ecological processes. An example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans. Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity. Impact Diversity in the ecosystem is significant to human existence for a variety of reasons. Ecosystem diversity boosts the availability of oxygen via the process of photosynthesis amongst plant organisms domiciled in the habitat. Diversity in an aquatic environment helps in the purification of water by plant varieties for use by humans. Diversity increases plant varieties which serves as a good source for medicines and herbs for human use. A lack of diversity in the ecosystem produces an opposite result. Examples Some examples of ecosystems that are rich in diversity are: Deserts Forests Large marine ecosystems Marine ecosystems Old-growth forests Rainforests Tundra Coral reefs Marine Ecosystem diversity as a result of evolutionary pressure Ecological diversity around the world can be directly linked to the evolutionary and selective pressures that constrain the diversity outcome of the ecosystems within different niches. Tundras, Rainforests, coral reefs and deciduous forests all are formed as a result of evolutionary pressures. Even seemingly small evolutionary interactions can have large impacts on the diversity of the ecosystems throughout the world. One of the best studied cases of this is of the honeybee's interaction with angiosperms on every continent in the world except Antarctica. In 2010, Robert Brodschneider and Karl Crailsheim conducted a study on the health and nutrition in honeybee colonies. The study focused on overall colony health, adult nutrition, and larva nutrition as a function of the effect of pesticides, monocultures and genetically modified crops to see if the anthropogenically created problems can have an effect pollination levels. The results indicate that human activity does have a role in the destruction of the fitness of the bee colony. The extinction or near extinction of these pollinators would result in many plants that feed humans on a wide scale needing alternative pollination methods. Crop pollinating insects are worth annually $14.6 billion to the US economy and the cost to hand pollinate over insect pollination is estimated to cost $5,715-$7,135 more per hectare. Not only will there be a cost increase but also an decrease in colony fitness, leading to a decrease in genetic diversity, which studies have shown has a direct link to the long-term survival of the honeybee colonies. According to a study, there are over 50 plants that are dependent on bee pollination, many of these being key staples to feeding the world. Another study conducted states that a lack of plant diversity will lead to a decline in the bee population fitness, and a low bee colony fitness has impacts on the fitness of plant ecosystem diversity. By allowing for bee pollination and working to reduce anthropogenically harmful footprints, bee pollination can increase genetic diversity of flora growth and create a unique ecosystem that is highly diverse and can provide a habitat and niche for many other organisms to thrive. Due to the evolutionary pressures of bees being located on six out of seven continents, there can be no denying the impact of pollinators on the ecosystem diversity. The pollen collected by the bees is harvested and used as an energy source for wintertime; this act of collecting pollen from local plants also has a more important effect of facilitating the movement of genes between organisms. The new evolutionary pressures that are largely anthropogenically catalyzed can potentially cause widespread collapse of ecosystems. In the north Atlantic Sea, a study was conducted that followed the effects of the human interaction on surrounding ocean habitats. They found that there was no habitat or trophic level that in some way was affected negatively by human interaction, and that much of the diversity of life was being stunted as a result.

Megatrends are trends that have an effect on a global scale. Some of the current megatrends relate to global threats. A megatrend strongly influences different spheres of life in many countries and at different levels, covering political, economic, natural environmental, social, and cultural dimensions. A megatrend is different than a shortlived product or consumer trend. John Naisbitt was a pioneer of future studies. His book “Megatrends: Ten New Directions Transforming Our Lives” was first published in 1982. It focused mainly on the United States but also attempted to present a global outlook. Naisbitt accurately predicted the change from industrialized to information societies. A growing number of research institutions, international organizations, and think tanks are reflecting on megatrends with the purpose of engaging in dialogue and influence policymaking and investments. Kuhn & Margellos proposed a framework to identify and prioritize megatrends which focuses on five criteria relating to the relevance of trends. The five key criteria are the following: Research and, particularly, research coverage of the trend by researchers and analysts from different disciplinary background in different countries and regions. Level of political attention for the trend in a significant number of countries and regions. Significant interest from global investors. This acknowledges that investments have great potential to promote trends. Media coverage of the trend. This refers to traditional media and social media. Strength of social movements and advocacy actions related to the trend. These factors represent different spheres of societies: scientific and research, state, and government institutions; financial and business sectors; media; and civil society. Kuhn & Margellos interviewed researchers and experts from more than 30 countries to prioritize megatrends resulting in the following megatrends: Climate Action and Sustainability Digitalization Inequality Demography Urbanization and Smart Cities Health and Nutrition Green Economy Sustainable Finance Multipolar World Order and the Future of Multilateralism Democracy and Governance Innovations Civilizational Developments: Diversity, Individualization and Loneliness, Gender Shift, and Identity Politics Migration. However, it is important to note that the identification and analysis of megatrends rely on the disciplinary and professional perspectives of researchers and experts, as well as the specific country or region upon which their analysis is focused. Economic implications Economically, megatrends can be exploited by enterprises to make profit. At least 7 megatrends have been identified by multinational investment and professional services companies: Technological progress, esp. in the internet domain Demographic change and social change Rapid global urbanization Climate change and resource depletion Emerging markets The impact of deepfakes and other synthetic media Microbiomes and synthetic biology References Futures studies Research

Ecocentrism

Ecocentrism (; from Greek: οἶκος oikos, 'house' and κέντρον kentron, 'center') is a term used by environmental philosophers and ecologists to denote a nature-centered, as opposed to human-centered (i.e., anthropocentric), system of values. The justification for ecocentrism usually consists in an ontological belief and subsequent ethical claim. The ontological belief denies that there are any existential divisions between human and non-human nature sufficient to claim that humans are either (a) the sole bearers of intrinsic value or (b) possess greater intrinsic value than non-human nature. Thus the subsequent ethical claim is for an equality of intrinsic value across human and non-human nature, or biospherical egalitarianism. Origin of term The ecocentric ethic was conceived by Aldo Leopold and recognizes that all species, including humans, are the product of a long evolutionary process and are inter-related in their life processes. The writings of Aldo Leopold and his idea of the land ethic and good environmental management are a key element to this philosophy. Ecocentrism focuses on the biotic community as a whole and strives to maintain ecosystem composition and ecological processes. The term also finds expression in the first principle of the deep ecology movement, as formulated by Arne Næss and George Sessions in 1984 which points out that anthropocentrism, which considers humans as the center of the universe and the pinnacle of all creation, is a difficult opponent for ecocentrism. Background Environmental thought and the various branches of the environmental movement are often classified into two intellectual camps: those that are considered anthropocentric, or "human-centred," in orientation and those considered biocentric, or "life-centred". This division has been described in other terminology as "shallow" ecology versus "deep" ecology and as "technocentrism" versus "ecocentrism". Ecocentrism can be seen as one stream of thought within environmentalism, the political and ethical movement that seeks to protect and improve the quality of the natural environment through changes to environmentally harmful human activities by adopting environmentally benign forms of political, economic, and social organization and through a reassessment of humanity's relationship with nature. In various ways, environmentalism claims that non-human organisms and the natural environment as a whole deserve consideration when appraising the morality of political, economic, and social policies. Environmental communication scholars suggest that anthropocentric ways of being and identities are maintained by various modes of cultural disciplinary power such as ridiculing, labelling, and silencing. Accordingly, the transition to more ecocentric ways of being and identities requires not only legal and economic structural change, but also the emergence of ecocultural practices that challenge anthropocentric disciplinary power and lead to the creation of ecocentric cultural norms. Relationship to other similar philosophies Anthropocentrism Ecocentrism is taken by its proponents to constitute a radical challenge to long-standing and deeply rooted anthropocentric attitudes in Western culture, science, and politics. Anthropocentrism is alleged to leave the case for the protection of non-human nature subject to the demands of human utility, and thus never more than contingent on the demands of human welfare. An ecocentric ethic, by contrast, is believed to be necessary in order to develop a non-contingent basis for protecting the natural world. Critics of ecocentrism have argued that it opens the doors to an anti-humanist morality that risks sacrificing human well-being for the sake of an ill-defined 'greater good'. Deep ecologist Arne Naess has identified anthropocentrism as a root cause of the ecological crisis, human overpopulation, and the extinctions of many non-human species. Lupinacci also points to anthropocentrism as a root cause of environmental degradation. Others point to the gradual historical realization that humans are not the centre of all things, that "A few hundred years ago, with some reluctance, Western people admitted that the planets, Sun and stars did not circle around their abode. In short, our thoughts and concepts though irreducibly anthropomorphic need not be anthropocentric." Industrocentrism It sees all things on earth as resources to be utilized by humans or to be commodified. This view is the opposite of anthropocentrism and ecocentrism. Technocentrism Ecocentrism is also contrasted with technocentrism (meaning values centred on technology) as two opposing perspectives on attitudes towards human technology and its ability to affect, control and even protect the environment. Ecocentrics, including "deep green" ecologists, see themselves as being subject to nature, rather than in control of it. They lack faith in modern technology and the bureaucracy attached to it. Ecocentrics will argue that the natural world should be respected for its processes and products, and that low impact technology and self-reliance is more desirable than technological control of nature. Technocentrics, including imperialists, have absolute faith in technology and industry and firmly believe that humans have control over nature. Although technocentrics may accept that environmental problems do exist, they do not see them as problems to be solved by a reduction in industry. Indeed, technocentrics see that the way forward for developed and developing countries and the solutions to our environmental problems today lie in scientific and technological advancement. Biocentrism The distinction between biocentrism and ecocentrism is ill-defined. Ecocentrism recognizes Earth's interactive living and non-living systems rather than just the Earth's organisms (biocentrism) as central in importance. The term has been used by those advocating "left biocentrism", combining deep ecology with an "anti-industrial and anti-capitalist" position (David Orton et al.).

Nature conservation

Nature conservation is the moral philosophy and conservation movement focused on protecting species from extinction, maintaining and restoring habitats, enhancing ecosystem services, and protecting biological diversity. A range of values underlie conservation, which can be guided by biocentrism, anthropocentrism, ecocentrism, and sentientism, environmental ideologies that inform ecocultural practices and identities. There has recently been a movement towards evidence-based conservation which calls for greater use of scientific evidence to improve the effectiveness of conservation efforts. As of 2018 15% of land and 7.3% of the oceans were protected. Many environmentalists set a target of protecting 30% of land and marine territory by 2030. In 2021, 16.64% of land and 7.9% of the oceans were protected. The 2022 IPCC report on climate impacts and adaptation, underlines the need to conserve 30% to 50% of the Earth's land, freshwater and ocean areas – echoing the 30% goal of the U.N.'s Convention on Biodiversity. Introduction Conservation goals include conserving habitat, preventing deforestation, maintaining soil organic matter, halting species extinction, reducing overfishing, and mitigating climate change. Different philosophical outlooks guide conservationists towards these different goals. The principal value underlying many expressions of the conservation ethic is that the natural world has intrinsic and intangible worth along with utilitarian value – a view carried forward by parts of the scientific conservation movement and some of the older Romantic schools of the ecology movement. Philosophers have attached intrinsic value to different aspects of nature, whether this is individual organisms (biocentrism) or ecological wholes such as species or ecosystems (ecoholism). More utilitarian schools of conservation have an anthropocentric outlook and seek a proper valuation of local and global impacts of human activity upon nature in their effect upon human wellbeing, now and to posterity. How such values are assessed and exchanged among people determines the social, political and personal restraints and imperatives by which conservation is practiced. This is a view common in the modern environmental movement. There is increasing interest in extending the responsibility for human wellbeing to include the welfare of sentient animals. In 2022 the United Kingdom introduced the Animal Welfare (Sentience) Act which lists all vertebrates, decapod crustaceans and cephalopods as sentient beings. Branches of conservation ethics focusing on sentient individuals include ecofeminism and compassionate conservation. In the United States of America, the year 1864 saw the publication of two books which laid the foundation for Romantic and Utilitarian conservation traditions in America. The posthumous publication of Henry David Thoreau's Walden established the grandeur of unspoiled nature as a citadel to nourish the spirit of man. A very different book from George Perkins Marsh, Man and Nature, later subtitled "The Earth as Modified by Human Action", catalogued his observations of man exhausting and altering the land from which his sustenance derives. The consumer conservation ethic has been defined as the attitudes and behaviors held and engaged in by individuals and families that ultimately serve to reduce overall societal consumption of energy. The conservation movement has emerged from the advancements of moral reasoning. Increasing numbers of philosophers and scientists have made its maturation possible by considering the relationships between human beings and organisms with the same rigor. This social ethic primarily relates to local purchasing, moral purchasing, the sustained, and efficient use of renewable resources, the moderation of destructive use of finite resources, and the prevention of harm to common resources such as air and water quality, the natural functions of a living earth, and cultural values in a built environment. These practices are used to slow down the accelerating rate in which extinction is occurring at. The origins of this ethic can be traced back to many different philosophical and religious beliefs; that is, these practices has been advocated for centuries. In the past, conservationism has been categorized under a spectrum of views, including anthropocentric, utilitarian conservationism, and radical eco-centric green eco-political views. More recently, the three major movements has been grouped to become what we now know as conservation ethic. The person credited with formulating the conservation ethic in the United States is former president, Theodore Roosevelt. Terminology The term "conservation" was coined by Gifford Pinchot in 1907. He told his close friend United States President Theodore Roosevelt who used it for a national conference of governors in 1908. In common usage, the term refers to the activity of systematically protecting natural resources such as forests, including biological diversity. Carl F. Jordan defines biological conservation as: While this usage is not new, the idea of biological conservation has been applied to the principles of ecology, biogeography, anthropology, economy, and sociology to maintain biodiversity. The term "conservation" itself may cover the concepts such as cultural diversity, genetic diversity, and the concept of movements environmental conservation, seedbank curation (preservation of seeds), and gene bank coordination (preservation of animals' genetic material). These are often summarized as the priority to respect diversity. Much recent movement in conservation can be considered a resistance to commercialism and globalization. Slow Food is a consequence of rejecting these as moral priorities, and embracing a slower and more locally focused lifestyle. Sustainable living is a lifestyle that people are beginning to adopt, promoting to make decisions that would help protect biodiversity. The small lifestyle changes that promote sustainability will eventually accumulate into the proliferation of biological diversity. Regulating the ecolabeling of products from fisheries, controlling for sustainable food production, or keeping the lights off during the day are some examples of sustainable living. However, sustainable living is not a simple and uncomplicated approach. A 1987 Brundtland Report expounds on the notion of sustainability as a process of change that looks different for everyone: "It is not a fixed state of harmony, but rather a process of change in which the exploitation of resources, the direction of investments, the orientation of technological development, and institutional change are made consistent with future as well as present needs. We do not pretend that the process is easy or straightforward." Simply put, sustainable living does make a difference by compiling many individual actions that encourage the protection of biological diversity. Practice Distinct trends exist regarding conservation development. The need for conserving land has only recently intensified during what some scholars refer to as the Capitalocene epoch. This era marks the beginning of colonialism, globalization, and the Industrial Revolution that has led to global land change as well as climate change. While many countries' efforts to preserve species and their habitats have been government-led, those in the North Western Europe tended to arise out of the middle-class and aristocratic interest in natural history, expressed at the level of the individual and the national, regional or local learned society. Thus countries like Britain, the Netherlands, Germany, etc. had what would be called non-governmental organizations – in the shape of the Royal Society for the Protection of Birds, National Trust and County Naturalists' Trusts (dating back to 1889, 1895, and 1912 respectively) Natuurmonumenten, Provincial Conservation Trusts for each Dutch province, Vogelbescherming, etc. – a long time before there were national parks and national nature reserves. This in part reflects the absence of wilderness areas in heavily cultivated Europe, as well as a longstanding interest in laissez-faire government in some countries, like the UK, leaving it as no coincidence that John Muir, the Scottish-born founder of the National Park movement (and hence of government-sponsored conservation) did his sterling work in the US, where he was the motor force behind the establishment of such national parks as Yosemite and Yellowstone. Nowadays, officially more than 10 percent of the world is legally protected in some way or the other, and in practice, private fundraising is insufficient to pay for the effective management of so much land with protective status. Protected areas in developing countries, where probably as many as 70–80 percent of the species of the world live, still enjoy very little effective management and protection. Some countries, such as Mexico, have non-profit civil organizations and landowners dedicated to protecting vast private property, such is the case of Hacienda Chichen's Maya Jungle Reserve and Bird Refuge in Chichen Itza, Yucatán. The Adopt A Ranger Foundation has calculated that worldwide about 140,000 rangers are needed for the protected areas in developing and transition countries. There are no data on how many rangers are employed at the moment, but probably less than half the protected areas in developing and transition countries have any rangers at all and those that have them are at least 50% short. This means that there would be a worldwide ranger deficit of 105,000 rangers in the developing and transition countries. The terms conservation and preservation are frequently conflated outside the academic, scientific, and professional kinds of literature. The United States' National Park Service offers the following explanation of the important ways in which these two terms represent very different conceptions of environmental protection ethics: During the environmental movement of the early 20th century, two opposing factions emerged: conservationists and preservationists. Conservationists sought to regulate human use while preservationists sought to eliminate human impact altogether." C. Anne Claus presents a distinction for conservation practices. Claus divides conservation into conservation-far and conservation-near. Conservation-far is the means of protecting nature by separating it and safeguarding it from humans. Means of doing this include the creation of preserves or national parks. They are meant to keep the flora and fauna away from human influence and have become a staple method in the west. Conservation-near however is conservation via connection. The method of reconnecting people to nature through traditions and beliefs to foster a desire to protect nature. The basis is that instead of forcing compliance to separate from nature onto the people, instead conservationists work with locals and their traditions to find conservation efforts that work for all. Evidence-based conservation Evidence-based conservation is the application of evidence in conservation management actions and policy making. It is defined as systematically assessing scientific information from published, peer-reviewed publications and texts, practitioners' experiences, independent expert assessment, and local and indigenous knowledge on a specific conservation topic. This includes assessing the current effectiveness of different management interventions, threats and emerging problems, and economic factors. Evidence-based conservation was organized based on the observations that decision making in conservation was based on intuition and/or practitioner experience often disregarding other forms of evidence of successes and failures (e.g. scientific information). This has led to costly and poor outcomes. Evidence-based conservation provides access to information that will support decision making through an evidence-based framework of "what works" in conservation. The evidence-based approach to conservation is based on evidence-based practice which started in medicine and later spread to nursing, education, psychology, and other fields. It is part of the larger movement towards evidence-based practices.

Environmental biotechnology

Environmental biotechnology is biotechnology that is applied to and used to study the natural environment. Environmental biotechnology could also imply that one try to harness biological process for commercial uses and exploitation. The International Society for Environmental Biotechnology defines environmental biotechnology as "the development, use and regulation of biological systems for remediation of contaminated environments (land, air, water), and for environment-friendly processes (green manufacturing technologies and sustainable development)". Environmental biotechnology can simply be described as "the optimal use of nature, in the form of plants, animals, bacteria, fungi and algae, to produce renewable energy, food and nutrients in a synergistic integrated cycle of profit making processes where the waste of each process becomes the feedstock for another process". Significance for agriculture, food security, climate change mitigation and adaptation and the MDGs The IAASTD has called for the advancement of small-scale agro-ecological farming systems and technology in order to achieve food security, climate change mitigation, climate change adaptation and the realisation of the Millennium Development Goals. Environmental biotechnology has been shown to play a significant role in agroecology in the form of zero waste agriculture and most significantly through the operation of over 15 million biogas digesters worldwide. Significance towards industrial biotechnology Consider the effluents of starch plant which has mixed up with a local water body like a lake or pond. We find huge deposits of starch which are not so easily taken up for degradation by microorganisms except for a few exemptions. Microorganisms from the polluted site are scan for genomic changes that allow them to degrade/utilize the starch better than other microbes of the same genus. The modified genes are then identified. The resultant genes are cloned into industrially significant microorganisms and are used for economically processes like in pharmaceutical industry, fermentations... etc.. Similar situations can be encountered in the case of marine oil spills which require cleanup, where microbes isolated from oil rich environments like oil wells, oil transfer pipelines...etc. have been found having the potential to degrade oil or use it as an energy source. Thus they serve as a remedy to oil spills. Microbes isolated from pesticide-contaminated soils may capable of utilizing the pesticides as energy source and hence when mixed along with bio-fertilizers, could serve as an insurance against increased pesticide-toxicity levels in agricultural platform. On the other hand, these newly introduced microorganisms could create an imbalance in the environment concerned. The mutual harmony in which the organisms in that particular environment existed may have to face alteration and we should be extremely careful so as to not disturb the mutual relationships already existing in the environment of both the benefits and the disadvantages would pave way for an improvised version of environmental biotechnology. Applications and Implications Humans have long been manipulating genetic material through breeding and modern genetic modification for optimizing crop yield, etc.. There can also be unexpected, negative health and environmental outcomes. Environmental biotechnology is about the balance between the applications that provide for these and the implications of manipulating genetic material. Textbooks address both the applications and implications. Environmental engineering texts addressing sewage treatment and biological principles are often now considered to be environmental biotechnology texts. These generally address the applications of biotechnologies, whereas the implications of these technologies are less often addressed; usually in books concerned with potential impacts and even catastrophic events.

Anthropocentrism

Anthropocentrism (; ) is the belief that human beings are the central or most important entity on the planet. The term can be used interchangeably with humanocentrism, and some refer to the concept as human supremacy or human exceptionalism. From an anthropocentric perspective, humankind is seen as separate from nature and superior to it, and other entities (animals, plants, minerals, etc.) are viewed as resources for humans to use. It is possible to distinguish between at least three types of anthropocentrism: perceptual anthropocentrism (which "characterizes paradigms informed by sense-data from human sensory organs"); descriptive anthropocentrism (which "characterizes paradigms that begin from, center upon, or are ordered around Homo sapiens / ‘the human'"); and normative anthropocentrism (which "characterizes paradigms that make assumptions or assertions about the superiority of Homo sapiens, its capacities, the primacy of its values, [or] its position in the universe"). Anthropocentrism tends to interpret the world in terms of human values and experiences. It is considered to be profoundly embedded in many modern human cultures and conscious acts. It is a major concept in the field of environmental ethics and environmental philosophy, where it is often considered to be the root cause of problems created by human action within the ecosphere. However, many proponents of anthropocentrism state that this is not necessarily the case: they argue that a sound long-term view acknowledges that the global environment must be made continually suitable for humans and that the real issue is shallow anthropocentrism. Environmental philosophy Some environmental philosophers have argued that anthropocentrism is a core part of a perceived human drive to dominate or "master" the Earth. Anthropocentrism is believed by some to be the central problematic concept in environmental philosophy, where it is used to draw attention to claims of a systematic bias in traditional Western attitudes to the non-human world that shapes humans' sense of self and identities. Val Plumwood argued that anthropocentrism plays an analogous role in green theory to androcentrism in feminist theory and ethnocentrism in anti-racist theory. Plumwood called human-centredness "anthrocentrism" to emphasise this parallel. One of the first extended philosophical essays addressing environmental ethics, John Passmore's Man's Responsibility for Nature has been criticised by defenders of deep ecology because of its anthropocentrism, often claimed to be constitutive of traditional Western moral thought. Indeed, defenders of anthropocentrism concerned with the ecological crisis contend that the maintenance of a healthy, sustainable environment is necessary for human well-being as opposed to for its own sake. According to William Grey, the problem with a "shallow" viewpoint is not that it is human-centred: "What's wrong with shallow views is not their concern about the well-being of humans, but that they do not really consider enough in what that well-being consists. According to this view, we need to develop an enriched, fortified anthropocentric notion of human interest to replace the dominant short-term, sectional and self-regarding conception." In turn, Plumwood in Environmental Culture: The Ecological Crisis of Reason argued that Grey's anthropocentrism is inadequate. Many devoted environmentalists encompass a somewhat anthropocentric-based philosophical view supporting the fact that they will argue in favor of saving the environment for the sake of human populations. Grey writes: "We should be concerned to promote a rich, diverse, and vibrant biosphere. Human flourishing may certainly be included as a legitimate part of such a flourishing." Such a concern for human flourishing amidst the flourishing of life as a whole, however, is said to be indistinguishable from that of deep ecology and biocentrism, which has been proposed as both an antithesis of anthropocentrism and as a generalised form of anthropocentrism. Judaeo–Christian traditions In the 1985 CBC series "A Planet For the Taking", David Suzuki explored the Old Testament roots of anthropocentrism and how it shaped human views of non-human animals. Some Christian proponents of anthropocentrism base their belief on the Bible, such as the verse 1:26 in the Book of Genesis: The use of the word "dominion" in the Genesis has been used to justify an anthropocentric worldview, but recently some have found it controversial, viewing it as possibly a mistranslation from the Hebrew. However an argument can be made that the Bible actually places all the importance on God as creator, and humans as merely another part of creation. Moses Maimonides, a Torah scholar who lived in the twelfth century AD, was renowned for his staunch opposition to anthropocentrism. He referred to humans as "just a drop in the bucket" and asserted that "humans are not the axis of the world". He also claimed that anthropocentric thinking is what leads humans to believe in the existence of evil things in nature. According to Rabbi Norman Lamm, Moses Maimonides "refuted the exaggerated ideas about the importance of man and urged us to abandon these fantasies. Catholic social teaching sees the pre-eminence of human beings over the rest of creation in terms of service rather than domination. Pope Francis, in his 2015 encyclical letter Laudato si' , notes that "an obsession with denying any pre-eminence to the human person" endangers the concern which should be shown to protecting and upholding the welfare of all people, which he argues should rank alongside the "care for our common home" which is the subject of his letter. In the same text he acknowledges that "a mistaken understanding" of Christian belief "has at times led us to justify mistreating nature, to exercise tyranny over creation": in such actions, Christian believers have "not [been] faithful to the treasures of wisdom which we have been called to protect and preserve. In his follow-up exhortation, Laudate Deum (2023) he refers to a preferable understanding of "the unique and central value of the human being amid the marvellous concert of all God's creatures" as a "situated anthropocentrism". Human rights Anthropocentrism is the grounding for some naturalistic concepts of human rights. Defenders of anthropocentrism argue that it is the necessary fundamental premise to defend universal human rights, since what matters morally is simply being human. For example, noted philosopher Mortimer J. Adler wrote, "Those who oppose injurious discrimination on the moral ground that all human beings, being equal in their humanity, should be treated equally in all those respects that concern their common humanity, would have no solid basis in fact to support their normative principle." Adler is stating here that denying what is now called human exceptionalism could lead to tyranny, writing that if humans ever came to believe that they do not possess a unique moral status, the intellectual foundation of their liberties collapses: "Why, then, should not groups of superior men be able to justify their enslavement, exploitation, or even genocide of inferior human groups on factual and moral grounds akin to those we now rely on to justify our treatment of the animals we harness as beasts of burden, that we butcher for food and clothing, or that we destroy as disease-bearing pests or as dangerous predators?" Author and anthropocentrism defender Wesley J. Smith from the Discovery Institute has written that human exceptionalism is what gives rise to human duties to each other, the natural world, and to treat animals humanely. Writing in A Rat is a Pig is a Dog is a Boy, a critique of animal rights ideology, "Because we are unquestionably a unique species—the only species capable of even contemplating ethical issues and assuming responsibilities—we uniquely are capable of apprehending the difference between right and wrong, good and evil, proper and improper conduct toward animals. Or to put it more succinctly, if being human isn't what requires us to treat animals humanely, what in the world does?" Moral status of animals Anthropocentrism is closely related to the notion of speciecism, defined by Richard D. Ryder as a "a prejudice or attitude of bias in favour of the interests of members of one's own species and against those of members of other species". One of the earliest of these critics was J. Howard Moore, who in The Universal Kinship (1906) argued that Charles Darwin's On the Origin of Species (1859) "sealed the doom" of anthropocentrism. While humans cognition is relatively advanced, many traits traditionally used to justify humanity exceptionalism (such as rationality, emotional complexity and social bonds) are not unique to humans. Research in ethology has shown that non-human animals, such as primates, elephants, and cetaceans, also demonstrate complex social structures, emotional depth, and problem-solving abilities. This challenges the claim that humans possess qualities absent in other animals, and which would justify denying moral status to them. Animal welfare proponents attribute moral consideration to all sentient animals, proportional to their ability to have positive or negative mental experiences. It is notably associated with the ethical theory of utilitarianism, which aims to maximize well-being. It is notably defended by Peter Singer. According to David Pearce, "other things being equal, equally strong interests should count equally." Jeremy Bentham is also known for raising early the issue of animal welfare, arguing that "the question is not, Can they reason? nor, Can they talk? but, Can they suffer?". Animal welfare proponents can in theory accept animal exploitation if the benefits outweigh the harms. But in practice, they generally consider that intensive animal farming causes a massive amount of suffering that outweighs the relatively minor benefit that humans get from consuming animals. Animal rights proponents argue that all animals have inherent rights, similar to human rights, and should not be used as means to human ends. Unlike animal welfare advocates, who focus on minimizing suffering, animal rights supporters often call for the total abolition of practices that exploit animals, such as intensive animal farming, animal testing, and hunting. Prominent figures like Tom Regan argue that animals are "subjects of a life" with inherent value, deserving moral consideration regardless of the potential benefits humans may derive from using them. Cognitive psychology In cognitive psychology, the term anthropocentric thinking has been defined as "the tendency to reason about unfamiliar biological species or processes by analogy to humans." Reasoning by analogy is an attractive thinking strategy, and it can be tempting to apply one's own experience of being human to other biological systems. For example, because death is commonly felt to be undesirable, it may be tempting to form the misconception that death at a cellular level or elsewhere in nature is similarly undesirable (whereas in reality programmed cell death is an essential physiological phenomenon, and ecosystems also rely on death). Conversely, anthropocentric thinking can also lead people to underattribute human characteristics to other organisms. For instance, it may be tempting to wrongly assume that an animal that is very different from humans, such as an insect, will not share particular biological characteristics, such as reproduction or blood circulation. Anthropocentric thinking has predominantly been studied in young children (mostly up to the age of 10) by developmental psychologists interested in its relevance to biology education. Children as young as 6 have been found to attribute human characteristics to species unfamiliar to them (in Japan), such as rabbits, grasshoppers or tulips. Although relatively little is known about its persistence at a later age, evidence exists that this pattern of human exceptionalist thinking can continue through young adulthood at least, even among students who have been increasingly educated in biology. The notion that anthropocentric thinking is an innate human characteristic has been challenged by study of American children raised in urban environments, among whom it appears to emerge between the ages of 3 and 5 years as an acquired perspective. Children's recourse to anthropocentric thinking seems to vary with their experience of nature, and cultural assumptions about the place of humans in the natural world. For example, whereas young children who kept goldfish were found to think of frogs as being more goldfish-like, other children tended to think of frogs in terms of humans. More generally, children raised in rural environments appear to use anthropocentric thinking less than their urban counterparts because of their greater familiarity with different species of animals and plants. Studies involving children from some of the indigenous peoples of the Americas have found little use of anthropocentric thinking. Study of children among the Wichí people in South America showed a tendency to think of living organisms in terms of their perceived taxonomic similarities, ecological considerations, and animistic traditions, resulting in a much less anthropocentric view of the natural world than is experienced by many children in Western societies. In popular culture In fiction from all eras and societies, there is fiction depicting the actions of humans to ride, eat, milk, and otherwise treat (non-human) animals as inferior. There are occasional fictional exceptions, such as talking animals as aberrations to the rule distinguishing people from animals. In science fiction, humanocentrism is the idea that humans, as both beings and as a species, are the superior sentients. Essentially the equivalent of racial supremacy on a galactic scale, it entails intolerant discrimination against sentient non-humans, much like race supremacists discriminate against those not of their race. A prime example of this concept is utilized as a story element for the Mass Effect series. After humanity's first contact results in a brief war, many humans in the series develop suspicious or even hostile attitudes towards the game's various alien races. By the time of the first game, which takes place several decades after the war, many humans still retain such sentiments in addition to forming 'pro-human' organizations. This idea is countered by anti-humanism. At times, this ideal also includes fear of and superiority over strong AIs and cyborgs, downplaying the ideas of integration, cybernetic revolts, machine rule and Tilden's Laws of Robotics. Mark Twain mocked the belief in human supremacy in Letters from the Earth (written c. 1909, published 1962). The Planet of the Apes franchise focuses on the analogy of apes becoming the dominant species in society and the fall of humans (see also human extinction). In the 1968 film, Taylor, a human states "take your stinking paws off me, you damn dirty ape!". In the 2001 film, this is contrasted with Attar (a gorilla)'s quote "take your stinking hands off me, you damn dirty human!". This links in with allusions that in becoming the dominant species apes are becoming more like humans (anthropomorphism). In the film Battle for the Planet of the Apes, Virgil, an orangutan states "ape has never killed ape, let alone an ape child. Aldo has killed an ape child. The branch did not break. It was cut with a sword." in reference to planned murder; a stereotypical human concept. Additionally, in Dawn of the Planet of the Apes, Caesar states "I always think...ape better than human. I see now...how much like them we are." In George Orwell's novel Animal Farm, this theme of anthropocentrism is also present. Whereas originally the animals planned for liberation from humans and animal equality, as evident from the "seven commandments" such as "whatever goes upon two legs is an enemy", "Whatever goes upon four legs, or has wings, is a friend", "All animals are equal"; the pigs would later abridge the commandments with statements such as "All animals are equal, but some animals are more equal than others", and "Four legs good, two legs better." The 2012 documentary The Superior Human? systematically analyzes anthropocentrism and concludes that value is fundamentally an opinion, and since life forms naturally value their own traits, most humans are misled to believe that they are actually more valuable than other species. This natural bias, according to the film, combined with a received sense of comfort and an excuse for exploitation of non-humans cause anthropocentrism to remain in society. In his 2009 book Eating Animals, Jonathan Foer describes anthropocentrism as "The conviction that humans are the pinnacle of evolution, the appropriate yardstick by which to measure the lives of other animals, and the rightful owners of everything that lives."

Climate change mitigation

Climate change mitigation (or decarbonisation) is action to limit the greenhouse gases in the atmosphere that cause climate change. Climate change mitigation actions include conserving energy and replacing fossil fuels with clean energy sources. Secondary mitigation strategies include changes to land use and removing carbon dioxide (CO2) from the atmosphere. Current climate change mitigation policies are insufficient as they would still result in global warming of about 2.7 °C by 2100, significantly above the 2015 Paris Agreement's goal of limiting global warming to below 2 °C. Solar energy and wind power can replace fossil fuels at the lowest cost compared to other renewable energy options. The availability of sunshine and wind is variable and can require electrical grid upgrades, such as using long-distance electricity transmission to group a range of power sources. Energy storage can also be used to even out power output, and demand management can limit power use when power generation is low. Cleanly generated electricity can usually replace fossil fuels for powering transportation, heating buildings, and running industrial processes. Certain processes are more difficult to decarbonise, such as air travel and cement production. Carbon capture and storage (CCS) can be an option to reduce net emissions in these circumstances, although fossil fuel power plants with CCS technology is currently a high cost climate change mitigation strategy. Human land use changes such as agriculture and deforestation cause about 1/4th of climate change. These changes impact how much is absorbed by plant matter and how much organic matter decays or burns to release . These changes are part of the fast carbon cycle, whereas fossil fuels release that was buried underground as part of the slow carbon cycle. Methane is a short lived greenhouse gas that is produced by decaying organic matter and livestock, as well as fossil fuel extraction. Land use changes can also impact precipitation patterns and the reflectivity of the surface of the Earth. It is possible to cut emissions from agriculture by reducing food waste, switching to a more plant-based diet (also referred to as low-carbon diet), and by improving farming processes. Various policies can encourage climate change mitigation. Carbon pricing systems have been set up that either tax emissions or cap total emissions and trade emission credits. Fossil fuel subsidies can be eliminated in favor of clean energy subsidies, and incentives offered for installing energy efficiency measures or switching to electric power sources. Another issue is overcoming environmental objections when constructing new clean energy sources and making grid modifications. Definitions and scope Climate change mitigation aims to sustain ecosystems to maintain human civilisation. This requires drastic cuts in greenhouse gas emissions . The Intergovernmental Panel on Climate Change (IPCC) defines mitigation (of climate change) as "a human intervention to reduce emissions or enhance the sinks of greenhouse gases". It is possible to approach various mitigation measures in parallel. This is because there is no single pathway to limit global warming to 1.5 or 2 °C. There are four types of measures: Sustainable energy and sustainable transport Energy conservation, including efficient energy use Sustainable agriculture and green industrial policy Enhancing carbon sinks and carbon dioxide removal (CDR), including carbon sequestration The IPCC defined carbon dioxide removal as "Anthropogenic activities removing carbon dioxide from the atmosphere and durably storing it in geological, terrestrial, or ocean reservoirs, or in products. It includes existing and potential anthropogenic enhancement of biological or geochemical sinks and direct air carbon dioxide capture and storage (DACCS), but excludes natural uptake not directly caused by human activities." Relationship with solar radiation modification (SRM) While solar radiation modification (SRM) could reduce surface temperatures, it temporarily masks climate change rather than addressing the root cause, which is greenhouse gases. SRM would work by altering how much solar radiation the Earth absorbs. Examples include reducing the amount of sunlight reaching the surface, reducing the optical thickness and lifetime of clouds, and changing the ability of the surface to reflect radiation. The IPCC describes SRM as a climate risk reduction strategy or supplementary option rather than a climate mitigation option. The terminology in this area is still evolving. Experts sometimes use the term geoengineering or climate engineering in the scientific literature for both CDR or SRM, if the techniques are used at a global scale. IPCC reports no longer use the terms geoengineering or climate engineering. Emission trends and pledges Greenhouse gas emissions from human activities strengthen the greenhouse effect. This contributes to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. Emissions in the 2010s averaged a record 56 billion tons (Gt) a year. In 2016, energy for electricity, heat and transport was responsible for 73.2% of GHG emissions. Direct industrial processes accounted for 5.2%, waste for 3.2% and agriculture, forestry and land use for 18.4%. Electricity generation and transport are major emitters. The largest single source is coal-fired power stations with 20% of greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest sources of anthropogenic methane emissions are agriculture, and gas venting and fugitive emissions from the fossil-fuel industry. The largest agricultural methane source is livestock. Agricultural soils emit nitrous oxide, partly due to fertilizers. There is now a political solution to the problem of fluorinated gases from refrigerants. This is because many countries have ratified the Kigali Amendment. Carbon dioxide is the dominant emitted greenhouse gas. Methane emissions almost have the same short-term impact. Nitrous oxide (N2O) and fluorinated gases (F-Gases) play a minor role. Livestock and manure produce 5.8% of all greenhouse gas emissions. But this depends on the time frame used to calculate the global warming potential of the respective gas. Greenhouse gas (GHG) emissions are measured in equivalents. Scientists determine their equivalents from their global warming potential (GWP). This depends on their lifetime in the atmosphere. There are widely used greenhouse gas accounting methods that convert volumes of methane, nitrous oxide and other greenhouse gases to carbon dioxide equivalents. Estimates largely depend on the ability of oceans and land sinks to absorb these gases. Short-lived climate pollutants (SLCPs) persist in the atmosphere for a period ranging from days to 15 years. Carbon dioxide can remain in the atmosphere for millennia. Short-lived climate pollutants include methane, hydrofluorocarbons (HFCs), tropospheric ozone and black carbon. Scientists increasingly use satellites to locate and measure greenhouse gas emissions and deforestation. Earlier, scientists largely relied on or calculated estimates of greenhouse gas emissions and governments' self-reported data. Needed emissions cuts The annual "Emissions Gap Report" by UNEP stated in 2022 that it was necessary to almost halve emissions. "To get on track for limiting global warming to 1.5°C, global annual GHG emissions must be reduced by 45 per cent compared with emissions projections under policies currently in place in just eight years, and they must continue to decline rapidly after 2030, to avoid exhausting the limited remaining atmospheric carbon budget." The report commented that the world should focus on broad-based economy-wide transformations and not incremental change. In 2022, the Intergovernmental Panel on Climate Change (IPCC) released its Sixth Assessment Report on climate change. It warned that greenhouse gas emissions must peak before 2025 at the latest and decline 43% by 2030 to have a good chance of limiting global warming to 1.5 °C (2.7 °F). Or in the words of Secretary-General of the United Nations António Guterres: "Main emitters must drastically cut emissions starting this year". Pledges Climate Action Tracker described the situation on 9 November 2021 as follows. The global temperature will rise by 2.7 °C by the end of the century with current policies and by 2.9 °C with nationally adopted policies. The temperature will rise by 2.4 °C if countries only implement the pledges for 2030. The rise would be 2.1 °C with the achievement of the long-term targets too. Full achievement of all announced targets would mean the rise in global temperature will peak at 1.9 °C and go down to 1.8 °C by the year 2100. Experts gather information about climate pledges in the Global Climate Action Portal - Nazca. The scientific community is checking their fulfilment. There has not been a definitive or detailed evaluation of most goals set for 2020. But it appears the world failed to meet most or all international goals set for that year. One update came during the 2021 United Nations Climate Change Conference in Glasgow. The group of researchers running the Climate Action Tracker looked at countries responsible for 85% of greenhouse gas emissions. It found that only four countries or political entities—the EU, UK, Chile and Costa Rica—have published a detailed official policyplan that describes the steps to realise 2030 mitigation targets. These four polities are responsible for 6% of global greenhouse gas emissions. In 2021 the US and EU launched the Global Methane Pledge to cut methane emissions by 30% by 2030. The UK, Argentina, Indonesia, Italy and Mexico joined the initiative. Ghana and Iraq signaled interest in joining. A White House summary of the meeting noted those countries represent six of the top 15 methane emitters globally. Israel also joined the initiative. Low-carbon energy The energy system includes the delivery and use of energy. It is the main emitter of carbon dioxide. Rapid and deep reductions in the carbon dioxide and other greenhouse gas emissions from the energy sector are necessary to limit global warming to well below 2 °C. IPCC recommendations include reducing fossil fuel consumption, increasing production from low- and zero carbon energy sources, and increasing use of electricity and alternative energy carriers. Nearly all scenarios and strategies involve a major increase in the use of renewable energy in combination with increased energy efficiency measures. It will be necessary to accelerate the deployment of renewable energy six-fold from 0.25% annual growth in 2015 to 1.5% to keep global warming under 2 °C. The competitiveness of renewable energy is a key to a rapid deployment. In 2020, onshore wind and solar photovoltaics were the cheapest source for new bulk electricity generation in many regions. Renewables may have higher storage costs but non-renewables may have higher clean-up costs. A carbon price can increase the competitiveness of renewable energy. Solar and wind energy Wind and sun can provide large amounts of low-carbon energy at competitive production costs. The IPCC estimates that these two mitigation options have the largest potential to reduce emissions before 2030 at low cost. Solar photovoltaics (PV) has become the cheapest way to generate electricity in many regions of the world. The growth of photovoltaics has been close to exponential. It has about doubled every three years since the 1990s. A different technology is concentrated solar power (CSP). This uses mirrors or lenses to concentrate a large area of sunlight on to a receiver. With CSP, the energy can be stored for a few hours. This provides supply in the evening. Solar water heating doubled between 2010 and 2019. Regions in the higher northern and southern latitudes have the greatest potential for wind power. Offshore wind farms are more expensive. But offshore units deliver more energy per installed capacity with less fluctuations. In most regions, wind power generation is higher in the winter when PV output is low. For this reason, combinations of wind and solar power lead to better-balanced systems. Other renewables Other well-established renewable energy forms include hydropower, bioenergy and geothermal energy. Hydroelectricity is electricity generated by hydropower and plays a leading role in countries like Brazil, Norway and China. but there are geographical limits and environmental issues. Tidal power can be used in coastal regions. Bioenergy can provide energy for electricity, heat and transport. Bioenergy, in particular biogas, can provide dispatchable electricity generation. While burning plant-derived biomass releases , the plants withdraw from the atmosphere while they grow. The technologies for producing, transporting and processing a fuel have a significant impact on the lifecycle emissions of the fuel. For example, aviation is starting to use renewable biofuels. Geothermal power is electrical power generated from geothermal energy. Geothermal electricity generation is currently used in 26 countries. Geothermal heating is in use in 70 countries. Integrating variable renewable energy Wind and solar power production does not consistently match demand. To deliver reliable electricity from variable renewable energy sources such as wind and solar, electrical power systems must be flexible. Most electrical grids were constructed for non-intermittent energy sources such as coal-fired power plants. The integration of larger amounts of solar and wind energy into the grid requires a change of the energy system; this is necessary to ensure that the supply of electricity matches demand. There are various ways to make the electricity system more flexible. In many places, wind and solar generation are complementary on a daily and a seasonal scale. There is more wind during the night and in winter when solar energy production is low. Linking different geographical regions through long-distance transmission lines also makes it possible to reduce variability. It is possible to shift energy demand in time. Energy demand management and the use of smart grids make it possible to match the times when variable energy production is highest. Sector coupling can provide further flexibility. This involves coupling the electricity sector to the heat and mobility sector via power-to-heat-systems and electric vehicles. Energy storage helps overcome barriers to intermittent renewable energy. The most commonly used and available storage method is pumped-storage hydroelectricity. This requires locations with large differences in height and access to water. Batteries are also in wide use. They typically store electricity for short periods. Batteries have low energy density. This and their cost makes them impractical for the large energy storage necessary to balance inter-seasonal variations in energy production. Some locations have implemented pumped hydro storage with capacity for multi-month usage. Nuclear power Nuclear power could complement renewables for electricity. On the other hand, environmental and security risks could outweigh the benefits. The construction of new nuclear reactors currently takes about 10 years. This is much longer than scaling up the deployment of wind and solar. And this timing gives rise to credit risks. However nuclear may be much cheaper in China. China is building a significant number of new power plants. the cost of extending nuclear power plant lifetimes is competitive with other electricity generation technologies if long term costs for nuclear waste disposal are excluded from the calculation. There is also no sufficient financial insurance for nuclear accidents. Replacing coal with natural gas Demand reduction Reducing demand for products and services that cause greenhouse gas emissions can help in mitigating climate change. One is to reduce demand by behavioural and cultural changes, for example by making changes in diet, especially the decision to reduce meat consumption, an effective action individuals take to fight climate change. Another is by reducing the demand by improving infrastructure, by building a good public transport network, for example. Lastly, changes in end-use technology can reduce energy demand. For instance a well-insulated house emits less than a poorly-insulated house. Mitigation options that reduce demand for products or services help people make personal choices to reduce their carbon footprint. This could be in their choice of transport or food. So these mitigation options have many social aspects that focus on demand reduction; they are therefore demand-side mitigation actions. For example, people with high socio-economic status often cause more greenhouse gas emissions than those from a lower status. If they reduce their emissions and promote green policies, these people could become low-carbon lifestyle role models. However, there are many psychological variables that influence consumers. These include awareness and perceived risk. Government policies can support or hinder demand-side mitigation options. For example, public policy can promote circular economy concepts which would support climate change mitigation. Reducing greenhouse gas emissions is linked to the sharing economy. There is a debate regarding the correlation of economic growth and emissions. It seems economic growth no longer necessarily means higher emissions. Energy conservation and efficiency Global primary energy demand exceeded 161,000 terawatt hours (TWh) in 2018. This refers to electricity, transport and heating including all losses. In transport and electricity production, fossil fuel usage has a low efficiency of less than 50%. Large amounts of heat in power plants and in motors of vehicles go to waste. The actual amount of energy consumed is significantly lower at 116,000 TWh. Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. One way is to use energy more efficiently. This means using less energy than before to produce the same service. Another way is to reduce the amount of service used. An example of this would be to drive less. Energy conservation is at the top of the sustainable energy hierarchy. When consumers reduce wastage and losses they can conserve energy. The upgrading of technology as well as the improvements to operations and maintenance can result in overall efficiency improvements. Efficient energy use (or energy efficiency) is the process of reducing the amount of energy required to provide products and services. Improved energy efficiency in buildings ("green buildings"), industrial processes and transportation could reduce the world's energy needs in 2050 by one third. This would help reduce global emissions of greenhouse gases. For example, insulating a building allows it to use less heating and cooling energy to achieve and maintain thermal comfort. Improvements in energy efficiency are generally achieved by adopting a more efficient technology or production process. Another way is to use commonly accepted methods to reduce energy losses. Lifestyle changes Individual action on climate change can include personal choices in many areas. These include diet, travel, household energy use, consumption of goods and services, and family size. People who wish to reduce their carbon footprint can take high-impact actions such as avoiding frequent flying and petrol-fuelled cars, eating mainly a plant-based diet, having fewer children, using clothes and electrical products for longer, and electrifying homes. These approaches are more practical for people in high-income countries with high-consumption lifestyles. Naturally, it is more difficult for those with lower income statuses to make these changes. This is because choices like electric-powered cars may not be available. Excessive consumption is more to blame for climate change than population increase. High-consumption lifestyles have a greater environmental impact, with the richest 10% of people emitting about half the total lifestyle emissions. Dietary change Some scientists say that avoiding meat and dairy foods is the single biggest way an individual can reduce their environmental impact. The widespread adoption of a vegetarian diet could cut food-related greenhouse gas emissions by 63% by 2050. China introduced new dietary guidelines in 2016 which aim to cut meat consumption by 50% and thereby reduce greenhouse gas emissions by 1Gt per year by 2030. Overall, food accounts for the largest share of consumption-based greenhouse gas emissions. It is responsible for nearly 20% of the global carbon footprint. Almost 15% of all anthropogenic greenhouse gas emissions have been attributed to the livestock sector. A shift towards plant-based diets would help to mitigate climate change. In particular, reducing meat consumption would help to reduce methane emissions. If high-income nations switched to a plant-based diet, vast amounts of land used for animal agriculture could be allowed to return to their natural state. This in turn has the potential to sequester 100 billion tonnes of by the end of the century. A comprehensive analysis found that plant based diets reduce emissions, water pollution and land use significantly (by 75%), while reducing the destruction of wildlife and usage of water. Family size Population growth has resulted in higher greenhouse gas emissions in most regions, particularly Africa. However, economic growth has a bigger effect than population growth. Rising incomes, changes in consumption and dietary patterns, as well as population growth, cause pressure on land and other natural resources. This leads to more greenhouse gas emissions and fewer carbon sinks. Some scholars have argued that humane policies to slow population growth should be part of a broad climate response together with policies that end fossil fuel use and encourage sustainable consumption. Advances in female education and reproductive health, especially voluntary family planning, can contribute to reducing population growth. Preserving and enhancing carbon sinks An important mitigation measure is "preserving and enhancing carbon sinks". This refers to the management of Earth's natural carbon sinks in a way that preserves or increases their capability to remove CO2 from the atmosphere and to store it durably. Scientists call this process also carbon sequestration. In the context of climate change mitigation, the IPCC defines a sink as "Any process, activity or mechanism which removes a greenhouse gas, an aerosol or a precursor of a greenhouse gas from the atmosphere". Globally, the two most important carbon sinks are vegetation and the ocean. To enhance the ability of ecosystems to sequester carbon, changes are necessary in agriculture and forestry. Examples are preventing deforestation and restoring natural ecosystems by reforestation. Scenarios that limit global warming to 1.5 °C typically project the large-scale use of carbon dioxide removal methods over the 21st century. There are concerns about over-reliance on these technologies, and their environmental impacts. But ecosystem restoration and reduced conversion are among the mitigation tools that can yield the most emissions reductions before 2030. Land-based mitigation options are referred to as "AFOLU mitigation options" in the 2022 IPCC report on mitigation. The abbreviation stands for "agriculture, forestry and other land use" The report described the economic mitigation potential from relevant activities around forests and ecosystems as follows: "the conservation, improved management, and restoration of forests and other ecosystems (coastal wetlands, peatlands, savannas and grasslands)". A high mitigation potential is found for reducing deforestation in tropical regions. The economic potential of these activities has been estimated to be 4.2 to 7.4 gigatonnes of carbon dioxide equivalent (GtCO2 -eq) per year. Forests Conservation The Stern Review on the economics of climate change stated in 2007 that curbing deforestation was a highly cost-effective way of reducing greenhouse gas emissions. About 95% of deforestation occurs in the tropics, where clearing of land for agriculture is one of the main causes. One forest conservation strategy is to transfer rights over land from public ownership to its indigenous inhabitants. Land concessions often go to powerful extractive companies. Conservation strategies that exclude and even evict humans, called fortress conservation, often lead to more exploitation of the land. This is because the native inhabitants turn to work for extractive companies to survive. Proforestation is promoting forests to capture their full ecological potential. This is a mitigation strategy as secondary forests that have regrown in abandoned farmland are found to have less biodiversity than the original old-growth forests. Original forests store 60% more carbon than these new forests. Strategies include rewilding and establishing wildlife corridors. Afforestation and reforestation Afforestation is the establishment of trees where there was previously no tree cover. Scenarios for new plantations covering up to 4000 million hectares (Mha) (6300 x 6300 km) suggest cumulative carbon storage of more than 900 GtC (2300 Gt) until 2100. But they are not a viable alternative to aggressive emissions reduction. This is because the plantations would need to be so large they would eliminate most natural ecosystems or reduce food production. One example is the Trillion Tree Campaign. However, preserving biodiversity is also important and for example not all grasslands are suitable for conversion into forests. Grasslands can even turn from carbon sinks to carbon sources. Reforestation is the restocking of existing depleted forests or in places where there were recently forests. Reforestation could save at least 1GtCO2 per year, at an estimated cost of $5–15 per tonne of carbon dioxide (tCO2). Restoring all degraded forests all over the world could capture about 205 GtC (750 Gt). With increased intensive agriculture and urbanization, there is an increase in the amount of abandoned farmland. By some estimates, for every acre of original old-growth forest cut down, more than 50 acres of new secondary forests are growing. In some countries, promoting regrowth on abandoned farmland could offset years of emissions. Planting new trees can be expensive and a risky investment. For example, about 80 percent of planted trees in the Sahel die within two years. Reforestation has higher carbon storage potential than afforestation. Even long-deforested areas still contain an "underground forest" of living roots and tree stumps. Helping native species sprout naturally is cheaper than planting new trees and they are more likely to survive. This could include pruning and coppicing to accelerate growth. This also provides woodfuel, which is otherwise a major source of deforestation. Such practices, called farmer-managed natural regeneration, are centuries old but the biggest obstacle towards implementation is ownership of the trees by the state. The state often sells timber rights to businesses which leads to locals uprooting seedlings because they see them as a liability. Legal aid for locals and changes to property law such as in Mali and Niger have led to significant changes. Scientists describe them as the largest positive environmental transformation in Africa. It is possible to discern from space the border between Niger and the more barren land in Nigeria, where the law has not changed. Soils There are many measures to increase soil carbon. This makes it complex and hard to measure and account for. One advantage is that there are fewer trade-offs for these measures than for BECCS or afforestation, for example. Globally, protecting healthy soils and restoring the soil carbon sponge could remove 7.6 billion tonnes of carbon dioxide from the atmosphere annually. This is more than the annual emissions of the US. Trees capture while growing above ground and exuding larger amounts of carbon below ground. Trees contribute to the building of a soil carbon sponge. Carbon formed above ground is released as immediately when wood is burned. If dead wood remains untouched, only some of the carbon returns to the atmosphere as decomposition proceeds. Farming can deplete soil carbon and render soil incapable of supporting life. However, conservation farming can protect carbon in soils, and repair damage over time. The farming practice of cover crops is a form of carbon farming. Methods that enhance carbon sequestration in soil include no-till farming, residue mulching and crop rotation. Scientists have described the best management practices for European soils to increase soil organic carbon. These are conversion of arable land to grassland, straw incorporation, reduced tillage, straw incorporation combined with reduced tillage, ley cropping system and cover crops. Another mitigation option is the production of biochar and its storage in soils This is the solid material that remains after the pyrolysis of biomass. Biochar production releases half of the carbon from the biomass—either released into the atmosphere or captured with CCS—and retains the other half in the stable biochar. It can endure in soil for thousands of years. Biochar may increase the soil fertility of acidic soils and increase agricultural productivity. During production of biochar, heat is released which may be used as bioenergy. Wetlands Wetland restoration is an important mitigation measure. It has moderate to great mitigation potential on a limited land area with low trade-offs and costs. Wetlands perform two important functions in relation to climate change. They can sequester carbon, converting carbon dioxide to solid plant material through photosynthesis. They also store and regulate water. Wetlands store about 45 million tonnes of carbon per year globally. Some wetlands are a significant source of methane emissions. Some also emit nitrous oxide. Peatland globally covers just 3% of the land's surface. But it stores up to 550 gigatonnes (Gt) of carbon. This represents 42% of all soil carbon and exceeds the carbon stored in all other vegetation types, including the world's forests. The threat to peatlands includes draining the areas for agriculture. Another threat is cutting down trees for lumber, as the trees help hold and fix the peatland. Additionally, peat is often sold for compost. It is possible to restore degraded peatlands by blocking drainage channels in the peatland, and allowing natural vegetation to recover. Mangroves, salt marshes and seagrasses make up the majority of the ocean's vegetated habitats. They only equal 0.05% of the plant biomass on land. But they store carbon 40 times faster than tropical forests. Bottom trawling, dredging for coastal development and fertilizer runoff have damaged coastal habitats. Notably, 85% of oyster reefs globally have been removed in the last two centuries. Oyster reefs clean the water and help other species thrive. This increases biomass in that area. In addition, oyster reefs mitigate the effects of climate change by reducing the force of waves from hurricanes. They also reduce the erosion from rising sea levels. Restoration of coastal wetlands is thought to be more cost-effective than restoration of inland wetlands. Deep ocean These options focus on the carbon which ocean reservoirs can store. They include ocean fertilization, ocean alkalinity enhancement or enhanced weathering. The IPCC found in 2022 ocean-based mitigation options currently have only limited deployment potential. But it assessed that their future mitigation potential is large. It found that in total, ocean-based methods could remove 1–100 Gt of per year. Their costs are in the order of US$40–500 per tonne of . Most of these options could also help to reduce ocean acidification. This is the drop in pH value caused by increased atmospheric CO2 concentrations. Blue carbon management is another type of ocean-based biological carbon dioxide removal (CDR). It can involve land-based as well as ocean-based measures. The term usually refers to the role that tidal marshes, mangroves and seagrasses can play in carbon sequestration. Some of these efforts can also take place in deep ocean waters. This is where the vast majority of ocean carbon is held. These ecosystems can contribute to climate change mitigation and also to ecosystem-based adaptation. Conversely, when blue carbon ecosystems are degraded or lost they release carbon back to the atmosphere. There is increasing interest in developing blue carbon potential. Scientists have found that in some cases these types of ecosystems remove far more carbon per area than terrestrial forests. However, the long-term effectiveness of blue carbon as a carbon dioxide removal solution remains under discussion. Enhanced weathering Enhanced weathering could remove 2–4 Gt of per year. This process aims to accelerate natural weathering by spreading finely ground silicate rock, such as basalt, onto surfaces. This speeds up chemical reactions between rocks, water, and air. It removes carbon dioxide from the atmosphere, permanently storing it in solid carbonate minerals or ocean alkalinity. Cost estimates are in the US$50–200 per tonne range of . Other methods to capture and store CO2 In addition to traditional land-based methods to remove carbon dioxide (CO2) from the air, other technologies are under development. These could reduce CO2 emissions and lower existing atmospheric CO2 levels. Carbon capture and storage (CCS) is a method to mitigate climate change by capturing CO2 from large point sources, such as cement factories or biomass power plants. It then stores it away safely instead of releasing it into the atmosphere. The IPCC estimates that the costs of halting global warming would double without CCS. Bioenergy with carbon capture and storage (BECCS) expands on the potential of CCS and aims to lower atmospheric CO2 levels. This process uses biomass grown for bioenergy. The biomass yields energy in useful forms such as electricity, heat, biofuels, etc. through consumption of the biomass via combustion, fermentation, or pyrolysis. The process captures the CO2 that was extracted from the atmosphere when it grew. It then stores it underground or via land application as biochar. This effectively removes it from the atmosphere. This makes BECCS a negative emissions technology (NET). Scientists estimated the potential range of negative emissions from BECCS in 2018 as 0–22 Gt per year. , BECCS was capturing approximately 2 million tonnes per year of CO2 annually. The cost and availability of biomass limits wide deployment of BECCS. BECCS currently forms a big part of achieving climate targets beyond 2050 in modelling, such as by the Integrated Assessment Models (IAMs) associated with the IPCC process. But many scientists are sceptical due to the risk of loss of biodiversity. Direct air capture is a process of capturing directly from the ambient air. This is in contrast to CCS which captures carbon from point sources. It generates a concentrated stream of for sequestration, utilization or production of carbon-neutral fuel and windgas. Artificial processes vary, and there are concerns about the long-term effects of some of these processes. Mitigation by sector Buildings The building sector accounts for 23% of global energy-related emissions. About half of the energy is used for space and water heating. Building insulation can reduce the primary energy demand significantly. Heat pump loads may also provide a flexible resource that can participate in demand response to integrate variable renewable resources into the grid. Solar water heating uses thermal energy directly. Sufficiency measures include moving to smaller houses when the needs of households change, mixed use of spaces and the collective use of devices. Planners and civil engineers can construct new buildings using passive solar building design, low-energy building, or zero-energy building techniques. In addition, it is possible to design buildings that are more energy-efficient to cool by using lighter-coloured, more reflective materials in the development of urban areas. Heat pumps efficiently heat buildings, and cool them by air conditioning. A modern heat pump typically transports around three to five times more thermal energy than electrical energy consumed. The amount depends on the coefficient of performance and the outside temperature. Refrigeration and air conditioning account for about 10% of global emissions caused by fossil fuel-based energy production and the use of fluorinated gases. Alternative cooling systems, such as passive cooling building design and passive daytime radiative cooling surfaces, can reduce air conditioning use. Suburbs and cities in hot and arid climates can significantly reduce energy consumption from cooling with daytime radiative cooling. Energy consumption for cooling is likely to rise significantly due to increasing heat and availability of devices in poorer countries. Of the 2.8 billion people living in the hottest parts of the world, only 8% currently have air conditioners, compared with 90% of people in the US and Japan. Adoption of air conditioners typically increases in warmer areas at above $10,000 annual household income. By combining energy efficiency improvements and decarbonising electricity for air conditioning with the transition away from super-polluting refrigerants, the world could avoid cumulative greenhouse gas emissions of up to 210–460 Gt-eq over the next four decades. A shift to renewable energy in the cooling sector comes with two advantages: Solar energy production with mid-day peaks corresponds with the load required for cooling and additionally, cooling has a large potential for load management in the electric grid. Urban planning Cities emitted 28 GtCO2-eq in 2020 of combined CO2 and emissions. This was from producing and consuming goods and services. Climate-smart urban planning aims to reduce sprawl to reduce the distance travelled. This lowers emissions from transportation. Switching from cars by improving walkability and cycling infrastructure is beneficial to a country's economy as a whole. Urban forestry, lakes and other blue and green infrastructure can reduce emissions directly and indirectly by reducing energy demand for cooling. Methane emissions from municipal solid waste can be reduced by segregation, composting, and recycling. Transport Transportation accounts for 15% of emissions worldwide. Increasing the use of public transport, low-carbon freight transport and cycling are important components of transport decarbonisation. Electric vehicles and environmentally friendly rail help to reduce the consumption of fossil fuels. In most cases, electric trains are more efficient than air transport and truck transport. Other efficiency means include improved public transport, smart mobility, carsharing and electric hybrids. Fossil-fuel for passenger cars can be included in emissions trading. Furthermore, moving away from a car-dominated transport system towards low-carbon advanced public transport system is important. Heavyweight, large personal vehicles (such as cars) require a lot of energy to move and take up much urban space. Several alternatives modes of transport are available to replace these. The European Union has made smart mobility part of its European Green Deal. In smart cities, smart mobility is also important. The World Bank is helping lower income countries buy electric buses. Their purchase price is higher than diesel buses. But lower running costs and health improvements due to cleaner air can offset this higher price. Between one quarter and three quarters of cars on the road by 2050 are forecast to be electric vehicles. Hydrogen may be a solution for long-distance heavy freight trucks, if batteries alone are too heavy. Shipping In the shipping industry, the use of liquefied natural gas (LNG) as a marine bunker fuel is driven by emissions regulations. Ship operators must switch from heavy fuel oil to more expensive oil-based fuels, implement costly flue gas treatment technologies or switch to LNG engines. Methane slip, when gas leaks unburned through the engine, lowers the advantages of LNG. Maersk, the world's biggest container shipping line and vessel operator, warns of stranded assets when investing in transitional fuels like LNG. The company lists green ammonia as one of the preferred fuel types of the future. It has announced the first carbon-neutral vessel on the water by 2023, running on carbon-neutral methanol. Cruise operators are trialling partially hydrogen-powered ships. Hybrid and all electric ferries are suitable for short distances. Norway's goal is an all electric fleet by 2025. Air transport Jet airliners contribute to climate change by emitting carbon dioxide, nitrogen oxides, contrails and particulates. Their radiative forcing is estimated at 1.3–1.4 that of alone, excluding induced cirrus cloud. In 2018, global commercial operations generated 2.4% of all emissions. The aviation industry has become more fuel efficient. But overall emissions have risen as the volume of air travel has increased. By 2020, aviation emissions were 70% higher than in 2005 and they could grow by 300% by 2050. It is possible to reduce aviation's environmental footprint by better fuel economy in aircraft. Optimising flight routes to lower non- effects on climate from nitrogen oxides, particulates or contrails can also help. Aviation biofuel, carbon emission trading and carbon offsetting, part of the 191 nation ICAO's Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), can lower emissions. Short-haul flight bans, train connections, personal choices and taxation on flights can lead to fewer flights. Hybrid electric aircraft and electric aircraft or hydrogen-powered aircraft may replace fossil fuel-powered aircraft. Experts expect emissions from aviation to rise in most projections, at least until 2040. They currently amount to 180 Mt of or 11% of transport emissions. Aviation biofuel and hydrogen can only cover a small proportion of flights in the coming years. Experts expect hybrid-driven aircraft to start commercial regional scheduled flights after 2030. Battery-powered aircraft are likely to enter the market after 2035. Under CORSIA, flight operators can purchase carbon offsets to cover their emissions above 2019 levels. CORSIA will be compulsory from 2027. Agriculture, forestry and land use Almost 20% of greenhouse gas emissions come from the agriculture and forestry sector. To significantly reduce these emissions, annual investments in the agriculture sector need to increase to $260 billion by 2030. The potential benefits from these investments are estimated at about $4.3 trillion by 2030, offering a substantial economic return of 16-to-1. Mitigation measures in the food system can be divided into four categories. These are demand-side changes, ecosystem protections, mitigation on farms, and mitigation in supply chains. On the demand side, limiting food waste is an effective way to reduce food emissions. Changes to a diet less reliant on animal products such as plant-based diets are also effective. With 21% of global methane emissions, cattle are a major driver of global warming. When rainforests are cut and the land is converted for grazing, the impact is even higher. In Brazil, producing 1 kg of beef can result in the emission of up to 335 kg CO2-eq. Other livestock, manure management and rice cultivation also emit greenhouse gases, in addition to fossil fuel combustion in agriculture. Important mitigation options for reducing the greenhouse gas emissions from livestock include genetic selection, introduction of methanotrophic bacteria into the rumen, vaccines, feeds, diet modification and grazing management. Other options are diet changes towards ruminant-free alternatives, such as milk substitutes and meat analogues. Non-ruminant livestock, such as poultry, emit far fewer GHGs. It is possible to cut methane emissions in rice cultivation by improved water management, combining dry seeding and one drawdown, or executing a sequence of wetting and drying. This results in emission reductions of up to 90% compared to full flooding and even increased yields. Industry Industry is the largest emitter of greenhouse gases when direct and indirect emissions are included. Electrification can reduce emissions from industry. Green hydrogen can play a major role in energy-intensive industries for which electricity is not an option. Further mitigation options involve the steel and cement industry, which can switch to a less polluting production process. Products can be made with less material to reduce emission-intensity and industrial processes can be made more efficient. Finally, circular economy measures reduce the need for new materials. This also saves on emissions that would have been released from the mining of collecting of those materials. The decarbonisation of cement production requires new technologies, and therefore investment in innovation. Bioconcrete is one possibility to reduce emissions. But no technology for mitigation is yet mature. So CCS will be necessary at least in the short-term. Another sector with a significant carbon footprint is the steel sector, which is responsible for about 7% of global emissions. Emissions can be reduced by using electric arc furnaces to melt and recycle scrap steel. To produce virgin steel without emissions, blast furnaces could be replaced by hydrogen direct reduced iron and electric arc furnaces. Alternatively, carbon capture and storage solutions can be used. Coal, gas and oil production often come with significant methane leakage. In the early 2020s some governments recognized the scale of the problem and introduced regulations. Methane leaks at oil and gas wells and processing plants are cost-effective to fix in countries which can easily trade gas internationally. There are leaks in countries where gas is cheap; such as Iran, Russia, and Turkmenistan. Nearly all this can be stopped by replacing old components and preventing routine flaring. Coalbed methane may continue leaking even after the mine has been closed. But it can be captured by drainage and/or ventilation systems. Fossil fuel firms do not always have financial incentives to tackle methane leakage. Co-benefits Co-benefits of climate change mitigation, also often referred to as ancillary benefits, were firstly dominated in the scientific literature by studies that describe how lower GHG emissions lead to better air quality and consequently impact human health positively. The scope of co-benefits research expanded to its economic, social, ecological and political implications. Positive secondary effects that occur from climate mitigation and adaptation measures have been mentioned in research since the 1990s. The IPCC first mentioned the role of co-benefits in 2001, followed by its fourth and fifth assessment cycle stressing improved working environment, reduced waste, health benefits and reduced capital expenditures. In the early 2000s the OECD was further fostering its efforts in promoting ancillary benefits. The IPCC pointed out in 2007: "Co-benefits of GHG mitigation can be an important decision criteria in analyses carried out by policy-makers, but they are often neglected" and added that the co-benefits are "not quantified, monetised or even identified by businesses and decision-makers". Appropriate consideration of co-benefits can greatly "influence policy decisions concerning the timing and level of mitigation action", and there can be "significant advantages to the national economy and technical innovation". An analysis of climate action in the UK found that public health benefits are a major component of the total benefits derived from climate action. Employment and economic development Co-benefits can positively impact employment, industrial development, states' energy independence and energy self-consumption. The deployment of renewable energies can foster job opportunities. Depending on the country and deployment scenario, replacing coal power plants with renewable energy can more than double the number of jobs per average MW capacity. Investments in renewable energies, especially in solar- and wind energy, can boost the value of production. Countries which rely on energy imports can enhance their energy independence and ensure supply security by deploying renewables. National energy generation from renewables lowers the demand for fossil fuel imports which scales up annual economic saving. The European Commission forecasts a shortage of 180,000 skilled workers in hydrogen production and 66,000 in solar photovoltaic power by 2030. Energy security A higher share of renewables can additionally lead to more energy security. Socioeconomic co-benefits have been analysed such as energy access in rural areas and improved rural livelihoods. Rural areas which are not fully electrified can benefit from the deployment of renewable energies. Solar-powered mini-grids can remain economically viable, cost-competitive and reduce the number of power cuts. Energy reliability has additional social implications: stable electricity improves the quality of education. The International Energy Agency (IEA) spelled out the "multiple benefits approach" of energy efficiency while the International Renewable Energy Agency (IRENA) operationalised the list of co-benefits of the renewable energy sector. Health and well-being The health benefits from climate change mitigation are significant. Potential measures can not only mitigate future health impacts from climate change but also improve health directly. Climate change mitigation is interconnected with various health co-benefits, such as those from reduced air pollution. Air pollution generated by fossil fuel combustion is both a major driver of global warming and the cause of a large number of annual deaths. Some estimates are as high as excess deaths during 2018. A 2023 study estimated that fossil fuels kill over 5 million people each year, as of 2019, by causing diseases such as heart attack, stroke and chronic obstructive pulmonary disease. Particulate air pollution kills by far the most, followed by ground-level ozone. Mitigation policies can also promote healthier diets such as less red meat, more active lifestyles, and increased exposure to green urban spaces. Access to urban green spaces provides benefits to mental health as well. The increased use of green and blue infrastructure can reduce the urban heat island effect. This reduces heat stress on people. Climate change adaptation Some mitigation measures have co-benefits in the area of climate change adaptation. This is for example the case for many nature-based solutions. Examples in the urban context include urban green and blue infrastructure which provide mitigation as well as adaptation benefits. This can be in the form of urban forests and street trees, green roofs and walls, urban agriculture and so forth. The mitigation is achieved through the conservation and expansion of carbon sinks and reduced energy use of buildings. Adaptation benefits come for example through reduced heat stress and flooding risk. Negative side effects Mitigation measures can also have negative side effects and risks. In agriculture and forestry, mitigation measures can affect biodiversity and ecosystem functioning. In renewable energy, mining for metals and minerals can increase threats to conservation areas. There is some research into ways to recycle solar panels and electronic waste. This would create a source for materials so there is no need to mine them. Scholars have found that discussions about risks and negative side effects of mitigation measures can lead to deadlock or the feeling that there are insuperable barriers to taking action. Costs and funding Several factors affect mitigation cost estimates. One is the baseline. This is a reference scenario that the alternative mitigation scenario is compared with. Others are the way costs are modelled, and assumptions about future government policy. Cost estimates for mitigation for specific regions depend on the quantity of emissions allowed for that region in future, as well as the timing of interventions. Mitigation costs will vary according to how and when emissions are cut. Early, well-planned action will minimize the costs. Globally, the benefits of keeping warming under 2 °C exceed the costs. Economists estimate the cost of climate change mitigation at between 1% and 2% of GDP. While this is a large sum, it is still far less than the subsidies governments provide to the ailing fossil fuel industry. The International Monetary Fund estimated this at more than $5 trillion per year. Another estimate says that financial flows for climate mitigation and adaptation are going to be over $800 billion per year. These financial requirements are predicted to exceed $4 trillion per year by 2030. Globally, limiting warming to 2 °C may result in higher economic benefits than economic costs. The economic repercussions of mitigation vary widely across regions and households, depending on policy design and level of international cooperation. Delayed global cooperation increases policy costs across regions, especially in those that are relatively carbon intensive at present. Pathways with uniform carbon values show higher mitigation costs in more carbon-intensive regions, in fossil-fuels exporting regions and in poorer regions. Aggregate quantifications expressed in GDP or monetary terms undervalue the economic effects on households in poorer countries. The actual effects on welfare and well-being are comparatively larger. Cost–benefit analysis may be unsuitable for analysing climate change mitigation as a whole. But it is still useful for analysing the difference between a 1.5 °C target and 2 °C. One way of estimating the cost of reducing emissions is by considering the likely costs of potential technological and output changes. Policymakers can compare the marginal abatement costs of different methods to assess the cost and amount of possible abatement over time. The marginal abatement costs of the various measures will differ by country, by sector, and over time. Eco-tariffs on only imports contribute to reduced global export competitiveness and to deindustrialization. Avoided costs of climate change effects It is possible to avoid some of the costs of the effects of climate change by limiting climate change. According to the Stern Review, inaction can be as high as the equivalent of losing at least 5% of global gross domestic product (GDP) each year, now and forever. This can be up to 20% of GDP or more when including a wider range of risks and impacts. But mitigating climate change will only cost about 2% of GDP. Also it may not be a good idea from a financial perspective to delay significant reductions in greenhouse gas emissions. Mitigation solutions are often evaluated in terms of costs and greenhouse gas reduction potentials. This fails to take into account the direct effects on human well-being. Distributing emissions abatement costs Mitigation at the speed and scale required to limit warming to 2 °C or below implies deep economic and structural changes. These raise multiple types of distributional concerns across regions, income classes and sectors. There have been different proposals on how to allocate responsibility for cutting emissions. These include egalitarianism, basic needs according to a minimum level of consumption, proportionality and the polluter-pays principle. A specific proposal is "equal per capita entitlements". This approach has two categories. In the first category, emissions are allocated according to national population. In the second category, emissions are allocated in a way that attempts to account for historical or cumulative emissions. Funding In order to reconcile economic development with mitigating carbon emissions, developing countries need particular support. This would be both financial and technical. The IPCC found that accelerated support would also tackle inequities in financial and economic vulnerability to climate change. One way to achieve this is the Kyoto Protocol's Clean Development Mechanism (CDM). Policies National policies Climate change mitigation policies can have a large and complex impact on the socio-economic status of individuals and countries This can be both positive and negative. It is important to design policies well and make them inclusive. Otherwise climate change mitigation measures can impose higher financial costs on poor households. An evaluation was conducted on 1,500 climate policy interventions made between 1998 and 2022. The interventions took place in 41 countries and across 6 continents, which together contributed 81% of the world's total emissions as of 2019. The evaluation found 63 successful interventions that resulted in significant emission reductions; the total release averted by these interventions was between 0.6 and 1.8 billion metric tonnes. The study focused on interventions with at least 4.5% emission reductions, but the researchers noted that meeting the reductions required by the Paris Agreement would require 23 billion metric tonnes per year. Generally, carbon pricing was found to be most effective in developed countries, while regulation was most effective in the developing countries. Complementary policy mixes benefited from synergies, and were mostly found to be more effective interventions than the implementation of isolated policies. The OECD recognise 48 distinct climate mitigation policies suitable for implementation at national level. Broadly, these can be categorised into three types: market based instruments, non market based instruments and other policies. Other policies include the Establishing an Independent climate advisory body. Non market based policies include the Implementing or tighening of Regulatory standards. These set technology or performance standards. They can be effective in addressing the market failure of informational barriers. Among market based policies, the carbon price has been found to be the most effective (at least for developed economies), and has its own section below. Additional market based policy instruments for climate change mitigation include: Emissions taxes These often require domestic emitters to pay a fixed fee or tax for every tonne of CO2 emissions they release into the atmosphere. Methane emissions from fossil fuel extraction are also occasionally taxed. But methane and nitrous oxide from agriculture are typically not subject to tax. Removing unhelpful subsidies: Many countries provide subsidies for activities that affect emissions. For example, significant fossil fuel subsidies are present in many countries. Phasing-out fossil fuel subsidies is crucial to address the climate crisis. It must however be done carefully to avoid protests and making poor people poorer. Creating helpful subsidies: Creating subsidies and financial incentives. One example is energy subsidies to support clean generation which is not yet commercially viable such as tidal power. Tradable permits: A permit system can limit emissions. Carbon pricing Imposing additional costs on greenhouse gas emissions can make fossil fuels less competitive and accelerate investments into low-carbon sources of energy. A growing number of countries raise a fixed carbon tax or participate in dynamic carbon emission trading (ETS) systems. In 2021, more than 21% of global greenhouse gas emissions were covered by a carbon price. This was a big increase from earlier due to the introduction of the Chinese national carbon trading scheme. Trading schemes offer the possibility to limit emission allowances to certain reduction targets. However, an oversupply of allowances keeps most ETS at low price levels around $10 with a low impact. This includes the Chinese ETS which started with $7/t in 2021. One exception is the European Union Emission Trading Scheme where prices began to rise in 2018. They reached about €80/t in 2022. This results in additional costs of about €0.04/KWh for coal and €0.02/KWh for gas combustion for electricity, depending on the emission intensity. Industries which have high energy requirements and high emissions often pay only very low energy taxes, or even none at all. While this is often part of national schemes, carbon offsets and credits can be part of a voluntary market as well such as on the international market. Notably, the company Blue Carbon of the UAE has bought ownership over an area equivalent to the United Kingdom to be preserved in return for carbon credits. International agreements Almost all countries are parties to the United Nations Framework Convention on Climate Change (UNFCCC). The ultimate objective of the UNFCCC is to stabilize atmospheric concentrations of greenhouse gases at a level that would prevent dangerous human interference with the climate system. Although not designed for this purpose, the Montreal Protocol has benefited climate change mitigation efforts. The Montreal Protocol is an international treaty that has successfully reduced emissions of ozone-depleting substances such as CFCs. These are also greenhouse gases. Paris Agreement History Historically efforts to deal with climate change have taken place at a multinational level. They involve attempts to reach a consensus decision at the United Nations, under the United Nations Framework Convention on Climate Change (UNFCCC). This is the dominant approach historically of engaging as many international governments as possible in taking action on a worldwide public issue. The Montreal Protocol in 1987 is a precedent that this approach can work. But some critics say the top-down framework of only utilizing the UNFCCC consensus approach is ineffective. They put forward counter-proposals of bottom-up governance. At this same time this would lessen the emphasis on the UNFCCC. The Kyoto Protocol to the UNFCCC adopted in 1997 set out legally binding emission reduction commitments for the "Annex 1" countries. The Protocol defined three international policy instruments ("Flexibility Mechanisms") which could be used by the Annex 1 countries to meet their emission reduction commitments. According to Bashmakov, use of these instruments could significantly reduce the costs for Annex 1 countries in meeting their emission reduction commitments. The Paris Agreement reached in 2015 succeeded the Kyoto Protocol which expired in 2020. Countries that ratified the Kyoto protocol committed to reduce their emissions of carbon dioxide and five other greenhouse gases, or engage in carbon emissions trading if they maintain or increase emissions of these gases. In 2015, the UNFCCC's "structured expert dialogue" came to the conclusion that, "in some regions and vulnerable ecosystems, high risks are projected even for warming above 1.5 °C". Together with the strong diplomatic voice of the poorest countries and the island nations in the Pacific, this expert finding was the driving force leading to the decision of the 2015 Paris Climate Conference to lay down this 1.5 °C long-term target on top of the existing 2 °C goal. Society and culture Commitments to divest More than 1000 organizations with investments worth US$8 trillion have made commitments to fossil fuel divestment. Socially responsible investing funds allow investors to invest in funds that meet high environmental, social and corporate governance (ESG) standards. Barriers There are individual, institutional and market barriers to achieving climate change mitigation. They differ for all the different mitigation options, regions and societies. Difficulties with accounting for carbon dioxide removal can act as economic barriers. This would apply to BECCS (bioenergy with carbon capture and storage). The strategies that companies follow can act as a barrier. But they can also accelerate decarbonisation. In order to decarbonise societies the state needs to play a predominant role. This is because it requires a massive coordination effort. This strong government role can only work well if there is social cohesion, political stability and trust. For land-based mitigation options, finance is a major barrier. Other barriers are cultural values, governance, accountability and institutional capacity. Developing countries face further barriers to mitigation. The cost of capital increased in the early 2020s. A lack of available capital and finance is common in developing countries. Together with the absence of regulatory standards, this barrier supports the proliferation of inefficient equipment. There are also financial and capacity barrier in many of these countries. One study estimates that only 0.12% of all funding for climate-related research goes on the social science of climate change mitigation. Vastly more funding goes on natural science studies of climate change. Considerable sums also go on studies of the impact of climate change and adaptation to it. Impacts of the COVID-19 pandemic The COVID-19 pandemic led some governments to shift their focus away from climate action, at least temporarily. This obstacle to environmental policy efforts may have contributed to slowed investment in green energy technologies. The economic slowdown resulting from COVID-19 added to this effect. In 2020, carbon dioxide emissions fell by 6.4% or 2.3 billion tonnes globally. Greenhouse gas emissions rebounded later in the pandemic as many countries began lifting restrictions. The direct impact of pandemic policies had a negligible long-term impact on climate change. Examples by country United States China China has committed to peak emissions by 2030 and reach net zero by 2060. Warming cannot be limited to 1.5 °C if any coal plants in China (without carbon capture) operate after 2045. The Chinese national carbon trading scheme started in 2021. European Union The European Commission estimates that an additional €477 million in annual investment is needed for the European Union to meet its Fit-for-55 decarbonization goals. In the European Union, government-driven policies and the European Green Deal have helped position greentech (as an example) as a vital area for venture capital investment. By 2023, venture capital in the EU's greentech sector equaled that of the United States, reflecting a concerted effort to drive innovation and mitigate climate change through targeted financial support. The European Green Deal has fostered policies that contributed to a 30% rise in venture capital for greentech companies in the EU from 2021 to 2023, despite a downturn in other sectors during the same period. While overall venture capital investment in the EU remains about six times lower than in the United States, the greentech sector has closed this gap significantly, attracting substantial funding. Key areas benefitting from increased investments are energy storage, circular economy initiatives, and agricultural technology. This is supported by the EU's ambitious goal to reduce greenhouse gas emissions by at least 55% by 2030.

Energy conservation

Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less and better sources of energy for continuous service) or changing one's behavior to use less and better source of service (for example, by driving vehicles which consume renewable energy or energy with more efficiency). Energy conservation can be achieved through efficient energy use, which has some advantages, including a reduction in greenhouse gas emissions and a smaller carbon footprint, as well as cost, water, and energy savings. Green engineering practices improve the life cycle of the components of machines which convert energy from one form into another. Energy can be conserved by reducing waste and losses, improving efficiency through technological upgrades, improving operations and maintenance, changing users' behaviors through user profiling or user activities, monitoring appliances, shifting load to off-peak hours, and providing energy-saving recommendations. Observing appliance usage, establishing an energy usage profile, and revealing energy consumption patterns in circumstances where energy is used poorly, can pinpoint user habits and behaviors in energy consumption. Appliance energy profiling helps identify inefficient appliances with high energy consumption and energy load. Seasonal variations also greatly influence energy load, as more air-conditioning is used in warmer seasons and heating in colder seasons. Achieving a balance between energy load and user comfort is complex yet essential for energy preservation. On a large scale, a few factors affect energy consumption trends, including political issues, technological developments, economic growth, and environmental concerns. User-oriented energy conservation User behavior has a significant effect on energy conservation. It involves user activity detection, profiling, and appliance interaction behaviors. User profiling consists of the identification of energy usage patterns of the user and replacing required system settings with automated settings that can be initiated on request. Within user profiling, personal characteristics are instrumental in affecting energy conservation behavior. These characteristics include household income, education, gender, age, and social norms. User behavior also relies on the impact of personality traits, social norms, and attitudes on energy conservation behavior. Beliefs and attitudes toward a convenient lifestyle, environmentally friendly transport, energy security, and residential location choices affect energy conservation behavior. As a result, energy conservation can be made possible by adopting pro-environmental behavior and energy-efficient systems. Education on approaches to energy conservation can result in wise energy use. The choices made by the users yield energy usage patterns. Rigorous analysis of these usage patterns identifies waste energy patterns, and improving those patterns may reduce significant energy load. Therefore, human behavior is critical to determining the implications of energy conservation measures and solving environmental problems. Substantial energy conservation may be achieved if users' habit loops are modified. User habits User habits significantly impact energy demand; thus, providing recommendations for improving user habits contributes to energy conservation. Micro-moments are essential in realizing energy consumption patterns and are identified using a variety of sensing units positioned in prominent areas across the home. The micro-moment is an event that changes the state of the appliance from inactive to active and helps in building users' energy consumption profiles according to their activities. Energy conservation can be achieved through user habits by following energy-saving recommendations at micro-moments. Unnecessary energy usage can be decreased by selecting a suitable schedule for appliance operation. Creating an effective scheduling system requires an understanding of user habits regarding appliances. Off-peak scheduling Many techniques for energy conservation comprise off-peak scheduling, which means operating an appliance in a low-price energy hour. This schedule can be achieved after user habits regarding appliance use are understood. Most energy providers divide the energy tariff into high and low-price hours; therefore, scheduling an appliance to work an off-peak hour will significantly reduce electricity bills. User activity detection User activity detection leads to the precise detection of appliances required for an activity. If an appliance is active but not required for a user's current activity, it wastes energy and can be turned off to conserve energy. The precise identification of user activities is necessary to achieve this method of energy conservation. Energy conservation opportunities by sector Buildings Existing buildings Energy conservation measures have primarily focused on technological innovations to improve efficiencies and financial incentives with theoretical explanations obtained from the mentioned analytical traditions. Existing buildings can improve energy efficiency by changing structural maintenance materials, adjusting the composition of air conditioning systems, selecting energy-saving equipment, and formulating subsidy policies. These measures can improve users' thermal comfort and reduce buildings' environmental impact. The selection of combinatorial optimization schemes that contain measures to guide and restrict users' behavior in addition to carrying out demand-side management can dynamically adjust energy consumption. At the same time, economic means should enable users to change their behavior and achieve a low-carbon life. Combination optimization and pricing incentives reduce building energy consumption and carbon emissions and reduce users' costs. Energy monitoring through energy audits can achieve energy efficiency in existing buildings. An energy audit is an inspection and analysis of energy use and flows for energy conservation in a structure, process, or system intending to reduce energy input without negatively affecting output. Energy audits can determine specific opportunities for energy conservation and efficiency measures as well as determine cost-effective strategies. Training professionals typically accomplish this and can be part of some national programs discussed above. The recent development of smartphone apps enables homeowners to complete relatively sophisticated energy audits themselves. For instance, smart thermostats can connect to standard HVAC systems to maintain energy-efficient indoor temperatures. In addition, data loggers can also be installed to monitor the interior temperature and humidity levels to provide a more precise understanding of the conditions. If the data gathered is compared with the users' perceptions of comfort, more fine-tuning of the interiors can be implemented (e.g., increasing the temperature where A.C. is used to prevent over-cooling). Building technologies and smart meters can allow commercial and residential energy users to visualize the impact their energy use can have in their workplaces or homes. Advanced real-time energy metering can help people save energy through their actions. Another approach towards energy conservation is the implementation of ECMs in commercial buildings, which often employ Energy Service Companies (ESCOs) experienced in energy performance contracting. This industry has been around since the 1970s and is more prevalent than ever today. The US-based organization EVO (Efficiency Valuation Organization) has created a set of guidelines for ESCOs to adhere to in evaluating the savings achieved by ECMs. These guidelines are called the International Performance Measurement and Verification Protocol (IPMVP). Energy efficiency can also be achieved by upgrading certain aspects of existing buildings. Firstly, making thermal improvements by adding insulation to crawl spaces and ensuring no leaks achieves an efficient building envelope, reducing the need for mechanical systems to heat and cool the space. High-performance insulation is also supported by adding double/triple-glazed windows to minimize thermal heat transmission. Minor upgrades in existing buildings include changing mixers to low flow greatly aids in water conservation, changing light bulbs to LED lights results in 70-90% less energy consumption than a standard incandescent or C.F.L. bulb, changing inefficient appliances with Energy Star-rated appliances will consume less energy, and finally adding vegetation in the landscape surrounding the building to function as a shading element. A window windcatcher can reduce the total energy use of a building by 23.3%. Energy conservation through users' behaviors requires understanding household occupants' lifestyle, social, and behavioral factors in analyzing energy consumption. This involves one-time investments in energy efficiency, such as purchasing new energy-efficient appliances or upgrading the building insulation without curtailing economic utility or the level of energy services, and energy curtailment behaviors which are theorized to be driven more by social-psychological factors and environmental concerns in comparison to the energy efficiency behaviors. Replacing existing appliances with newer and more efficient ones leads to energy efficiency as less energy is wasted throughout. Overall, energy efficiency behaviors are identified more with one-time, cost-incurring investments in efficient appliances and retrofits, while energy curtailment behaviors include repetitive, low-cost energy-saving efforts. To identify and optimize residential energy use, conventional and behavioral economics, technology adoption theory and attitude-based decision-making, social and environmental psychology, and sociology must be analyzed. The techno-economic and psychological literature analysis focuses on the individual attitude, behavior, and choice/context/external conditions. In contrast, the sociological literature relies more on the energy consumption practices shaped by the social, cultural, and economic factors in a dynamic setting. New buildings Many steps can be taken toward energy conservation and efficiency when designing new buildings. Firstly, the building can be designed to optimize building performance by having an efficient building envelope with high-performing insulation and window glazing systems, window facades strategically oriented to optimize daylighting, shading elements to mitigate unwanted glare, and passive energy systems for appliances. In passive solar building designs, windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. The key to designing a passive solar building is to best take advantage of the local climate. Elements to be considered include window placement and glazing type, thermal insulation, thermal mass, and shading. Optimizing daylighting can decrease energy waste from incandescent bulbs, windows, and balconies, allow natural ventilation, reduce the need for heating and cooling, low flow mixers aid in water conservation, and upgrade to Energy star rated appliances consume less energy. Designing a building according to LEED guidelines while incorporating smart home technology can help save a lot of energy and money in the long run. Passive solar design techniques can be applied most easily to new buildings, but existing buildings can be retrofitted. Mainly, energy conservation is achieved by modifying user habits or providing an energy-saving recommendation of curtailing an appliance or scheduling it to low-price energy tariff hours. Besides changing user habits and appliance control, identifying irrelevant appliances concerning user activities in smart homes saves energy. Smart home technology can advise users on energy-saving strategies according to their behavior, encouraging behavioral change that leads to energy conservation. This guidance includes reminders to turn off lights, leakage sensors to prevent plumbing issues, running appliances on off-peak hours, and smart sensors that save energy. Such technology learns user-appliance activity patterns, gives a complete overview of various energy-consuming appliances, and can provide guidance to improve these patterns to contribute to energy conservation. As a result, they can strategically schedule appliances by monitoring the energy consumption profiles of the appliances, schedule devices to the energy-efficient mode, or plan to work during off-peak hours. Appliance-oriented approaches emphasize appliance profiling, curtailing, and scheduling to off-peak hours, as supervision of appliances is key to energy preservation. It usually leads to appliance curtailment in which an appliance is either scheduled to work another time or is turned off. Appliance curtailment involves appliance recognition, activity-appliances model, unattended appliance detection, and energy conservation service. The appliance recognition module detects active appliances to identify the activities of smart home users. After identifying users' activities, the association between the functional appliances and user activities is established. The unattended appliance detection module looks for active appliances but is unrelated to user activity. These functional appliances waste energy and can be turned off by providing recommendations to the user. Based on the smart home recommendations, users can give weight to certain appliances that increase user comfort and satisfaction while conserving energy. Energy consumption models of energy consumption of appliances and the level of comfort they create can balance priorities among smart home comfort levels and energy consumption. According to Kashimoto, Ogura, Yamamoto, Yasumoto, and Ito, the energy supply reduces based on the historical state of the appliance and increases according to the comfort level requirement of the user, leading to a targeted energy-saving ratio. Scenarios-based energy consumption can be employed as a strategy for energy conservation, with each scenario encompassing a specific set of rules for energy consumption. Transportation Transporting people, goods, and services represented 29% of U.S. energy consumption in 2007. The transportation sector also accounted for about 33% of U.S. carbon dioxide emissions in 2006, with highway vehicles accounting for about 84% of that, making transportation an essential target for addressing global climate change (E.I.A., 2008). Suburban infrastructure evolved during an age of relatively easy access to fossil fuels, leading to transportation-dependent living systems.[citation needed] The amount of energy used to transport people to and from a facility, whether they are commuters, customers, vendors, or homeowners, is known as the transportation energy intensity of the building. Land is developing at a faster rate than population growth, leading to urban sprawl and, therefore, high transportation energy intensity as more people need to commute longer distances to jobs. As a result, the location of a building is essential in decreasing embodied emissions. In transportation, state and local efforts in energy conservation and efficiency measures tend to be more targeted and smaller in scale. However, with more robust fuel economy standards, new targets for the use of alternative transportation fuels, and new efforts in electric and hybrid electric vehicles, EPAct05 and EISA provide a new set of national policy signals and financial incentives to the private sector and state and local governments for the transportation sector. Zoning reforms that allow greater urban density and designs for walking and bicycling can greatly reduce energy consumed for transportation. Many Americans work in jobs that allow for remote work instead of commuting daily, which is a significant opportunity to conserve energy.[citation needed] Intelligent transportation systems (ITS) provide a solution to traffic congestion and C.E.s caused by increased vehicles. ITS combines improvements in information technology and systems, communications, sensors, controllers, and advanced mathematical methods with the traditional world of transportation infrastructure. It improves traffic safety and mobility, reduces environmental impact, promotes sustainable transportation, and increases productivity. The ITS strengthens the connection and cooperation between people, vehicles, roads, and the environment while improving road capacity, reducing traffic accidents, and improving transportation efficiency and safety by alleviating traffic congestion and reducing pollution. It makes full use of traffic information as an application service, which can enhance the operational efficiency of existing traffic facilities. The most significant energy-saving potential is that there are the most problems in urban transportation in various countries, such as management systems, policies and regulations, planning, technology, operation, and management mechanism. Improvements in one or several aspects will improve road transportation. Efficiency has a positive impact, which leads to the improvement of the urban traffic environment and efficiency. In addition to ITS, transit-oriented development (T.O.D.) significantly improves transportation in urban areas by emphasizing density, proximity to transit, diversity of uses, and streetscape design. Density is important for optimizing location and is a way to cut down on driving. Planners can regulate development rights by exchanging them from ecologically sensitive areas to growth-friendly zones according to density transfer procedures. Distance is defined as the accessibility of rail and bus transits, which serve as deterrents for driving. For transit-oriented development to be feasible, transportation stops must be close to where people live. Diversity refers to mixed-use areas that offer essential services close to homes and offices and include residential spaces for different socioeconomic categories, commercial and retail. This creates a pedestrian shed where one area can meet people's everyday needs on foot. Lastly, the streetscapes design involves minimal parking and walkable areas that calm traffic. Generous parking incentivizes people to use cars, whereas minimal and expensive parking deters commuters. At the same time, streetscapes can be designed to incorporate bicycling lanes and designated bicycle paths and trails. People may commute by bicycle to work without being concerned about their bicycles becoming wet because of covered bicycle storage. This encourages commuters to use bicycles rather than other modes of transportation and contributes to energy saving. People will be happy to walk a few blocks from a train stop if there are attractive, pedestrian-friendly outdoor spaces nearby with good lighting, park benches, outdoor tables at cafés, shade tree plantings, pedestrian courts that are blocked off to cars, and public internet connection. Additionally, this strategy calms traffic, improving the intended pedestrian environment. New urban planning schemes can be designed to improve connectivity in cities through networks of interconnected streets that spread out traffic flow, slow down vehicles, and make walking more pleasant. By dividing the number of road links by the number of road nodes, the connectivity index is calculated. The higher the connectivity index, the greater the route choices and the better the pedestrian access. Realizing the transportation impacts associated with buildings allows commuters to take steps toward energy conservation. Connectivity encourages energy-conserving behaviors as commuters use fewer cars, walk and bike more, and use public transportation. For commuters who do not have the option of public transportation, smaller vehicles that are hybrid or have better mileage can be used. Consumer products Homeowners implementing ECMs in their residential buildings often start with an energy audit. This is a way homeowners look at what areas of their homes are using, and possibly losing energy. Residential energy auditors are accredited by the Building Performance Institute (BPI) or the Residential Energy Services Network (RESNET). Homeowners can hire a professional or do it themselves or use a smartphone to help do an audit. Energy conservation measures are often combined into larger guaranteed Energy Savings Performance Contracts to maximize energy savings while minimizing disruption to building occupants by coordinating renovations. Some ECMs cost less to implement yet return higher energy savings. Traditionally, lighting projects were a good example of "low hanging fruit" that could be used to drive implementation of more substantial upgrades to HVAC systems in large facilities. Smaller buildings might combine window replacement with modern insulation using advanced building foams to improve energy for performance. Energy dashboard projects are a new kind of ECM that relies on the behavioral change of building occupants to save energy. When implemented as part of a program, case studies, such as that for the DC Schools, report energy savings up 30%. Under the right circumstances, open energy dashboards can even be implemented for free to improve upon these savings even more. Consumers are often poorly informed of the savings of energy-efficient products. A prominent example of this is the energy savings that can be made by replacing an incandescent light bulb with a more modern alternative. When purchasing light bulbs, many consumers opt for cheap incandescent bulbs, failing to take into account their higher energy costs and lower lifespans when compared to modern compact fluorescent and LED bulbs. Although these energy-efficient alternatives have a higher upfront cost, their long lifespan and low energy use can save consumers a considerable amount of money. The price of LED bulbs has also been steadily decreasing in the past five years due to improvements in semiconductor technology. Many LED bulbs on the market qualify for utility rebates that further reduce the price of the purchase to the consumer. Estimates by the U.S. Department of Energy state that widespread adoption of LED lighting over the next 20 years could result in about $265 billion worth of savings in United States energy costs. The research one must put into conserving energy is often too time-consuming and costly for the average consumer when there are cheaper products and technology available using today's fossil fuels. Some governments and NGOs are attempting to reduce this complexity with Eco-labels that make differences in energy efficiency easy to research while shopping. To provide the kind of information and support people need to invest money, time and effort in energy conservation, it is important to understand and link to people's topical concerns. For instance, some retailers argue that bright lighting stimulates purchasing. However, health studies have demonstrated that headache, stress, blood pressure, fatigue and worker error all generally increase with the common over-illumination present in many workplace and retail settings. It has been shown that natural daylighting increases productivity levels of workers, while reducing energy consumption. In warm climates where air conditioning is used, any household device that gives off heat will result in a larger load on the cooling system. Items such as stoves, dishwashers, clothes dryers, hot water, and incandescent lighting all add heat to the home. Low-power or insulated versions of these devices give off less heat for the air conditioning to remove. The air conditioning system can also improve efficiency by using a heat sink that is cooler than the standard air heat exchanger, such as geothermal or water. In cold climates, heating air and water is a major demand for household energy use. Significant energy reductions are possible by using different technologies. Heat pumps are a more efficient alternative to electrical resistance heaters for warming air or water. A variety of efficient clothes dryers are available, and the clothes lines requires no energy- only time. Natural-gas (or bio-gas) condensing boilers and hot-air furnaces increase efficiency over standard hot-flue models. Standard electric boilers can be made to run only at hours of the day when they are needed by means of a time switch. This decreases energy use vastly. In showers, a semi-closed-loop system could be used. New construction implementing heat exchangers can capture heat from wastewater or exhaust air in bathrooms, laundry, and kitchens. In both warm and cold climate extremes, airtight thermal insulated construction is the largest factor determining the efficiency of a home. Insulation is added to minimize the flow of heat to or from the home, but can be labor-intensive to retrofit to an existing home. Energy conservation by countries Asia Although energy efficiency is expected to play a vital role in cost-effectively cutting energy demand, only a small part of its economic potential is exploited in Asia. Governments have implemented a range of subsidies such as cash grants, cheap credit, tax exemptions, and co-financing with public-sector funds to encourage energy-efficiency initiatives across several sectors. Governments in the Asia-Pacific region have implemented a range of information provision and labeling programs for buildings, appliances, and the transportation and industrial sectors. Information programs can simply provide data, such as fuel-economy labels, or actively seek to encourage behavioral changes, such as Japan's Cool Biz campaign that encourages setting air conditioners at 28-degrees Celsius and allowing employees to dress casually in the summer. China's government has launched a series of policies since 2005 to effectively promote the goal of reducing energy-saving emissions; however, road transportation, the fastest-growing energy-consuming sector in the transportation industry, lacks specific, operational, and systematic energy-saving plans. Road transportation is the highest priority to achieve energy conservation effectively and reduce emissions, particularly since social and economic development has entered the "new norm" period. Generally speaking, the government should make comprehensive plans for conservation and emissions reduction in the road transportation industry within the three dimensions of demand, structure, and technology. For example, encouraging trips using public transportation and new transportation modes such as car-sharing and increasing investment in new energy vehicles in structure reform, etc. European Union At the end of 2006, the European Union (EU) pledged to cut its annual consumption of primary energy by 20% by 2020. The EU Energy Efficiency Directive 2012 mandates energy efficiency improvements within the EU. As part of the EU's SAVE program, aimed at promoting energy efficiency and encouraging energy-saving behavior, the Boiler Efficiency Directive specifies minimum levels of efficiency for boilers using liquid or gaseous fuels. There is steady progress on energy regulation implementation in Europe, North America, and Asia, with the highest number of building energy standards being adopted and implemented. Moreover, the performance of Europe is highly encouraging concerning energy standard activities. They recorded the highest percentage of mandatory energy standards compared to the other five regions. In 2050, energy savings in Europe can reach 67% of the 2019 baseline scenario, amounting to a demand of 361 Mtoe in an "energy efficiency first" societal trend scenario. A condition is that there be no rebound effect, for otherwise the savings are 32% only or energy use may even increase by 42% if techno-economic potentials are not realized. Germany has reduced its primary energy consumption by 11% from 1990 to 2015 and set itself goals of reducing it by 30% by the year 2030 and by 50% by the year 2050 in comparison to the level of 2008. India The Petroleum Conservation Research Association (PCRA) is an Indian governmental body created in 1978 that engages in promoting energy efficiency and conservation in every walk of life. In the recent past, PCRA has organised mass media campaigns in television, radio, and print media. This is an impact-assessment survey by a third party that revealed that due to these larger campaigns by PCRA, the public's overall awareness level has gone up leading to the saving of fossil fuels worth crores of rupees, besides reducing pollution. The Bureau of Energy Efficiency is an Indian government organization created in 2001 that is responsible for promoting energy efficiency and conservation. Protection and Conservation of Natural Resources are done by Community Natural Resources Management (CNRM). Iran Supreme leader of Iran Ali Khamenei had regularly criticized energy administration and high fuel consumption. Japan Since the 1973 oil crisis, energy conservation has been an issue in Japan. All oil-based fuel is imported, so domestic sustainable energy is being developed. The Energy Conservation Center promotes energy efficiency in every aspect of Japan. Public entities are implementing the efficient use of energy for industries and research. It includes projects such as the Top Runner Program. In this project, new appliances are regularly tested on efficiency, and the most efficient ones are made the standard. Middle East The Middle East holds 40% of the world's crude oil reserves and 23% of its natural gas reserves. Conservation of domestic fossil fuels is, therefore, a legitimate priority for the Gulf countries, given domestic needs as well as the global market for these products. Energy subsidies are the chief barrier to conservation in the Gulf. Residential electricity prices can be a tenth of U.S. rates. As a result, increased tariff revenues from gas, electricity, and water sales would encourage investment in natural gas exploration and production and generation capacity, helping to alleviate future shortages. Households in the MENA region are responsible for 53% of energy use in Saudi Arabia and 57% of the UAE's ecological footprint. This is partially due to poorly designed and constructed buildings, mainly under a cheap energy model that has left them without contemporary control technology or even proper insulation and efficient appliances. Building energy consumption can be cut by 20% under a combination of insulation, efficient windows and appliances, shading, reflective roofing, and a host of automated controls that adjust energy use. Governments could also set minimum energy efficiency and water use standards on importing appliances sold inside their countries, effectively banning the sale of inefficient air conditioners, dishwashers, and washing machines. Administration of the laws would essentially be a function of national customs services. Governments could go further, offering incentives – or mandates – that air conditioners of a certain age be replaced. Lebanon In Lebanon and since 2002 The Lebanese Center for Energy Conservation (LCEC) has been promoting the development of efficient and rational uses of energy and the use of renewable energy at the consumer level. It was created as a project financed by the International Environment Facility (GEF) and the Ministry of Energy Water (MEW) under the management of the United Nations Development Programme (UNDP) and gradually established itself as an independent technical national center although it continues to be supported by the United Nations Development Programme (UNDP) as indicated in the Memorandum of Understanding (MoU) signed between MEW and UNDP on 18 June 2007. Nepal Until recently, Nepal has been focusing on the exploitation of its huge water resources to produce hydropower. Demand-side management and energy conservation were not in the focus of government action. In 2009, bilateral Development Cooperation between Nepal and the Federal Republic of Germany has agreed upon the joint implementation of the "Nepal Energy Efficiency Programme". The lead executing agencies for the implementation are the Water and Energy Commission Secretariat (WECS). The aim of the program is the promotion of energy efficiency in policymaking, in rural and urban households as well as in the industry. Due to the lack of a government organization that promotes energy efficiency in the country, the Federation of Nepalese Chambers of Commerce and Industry (FNCCI) has established the Energy Efficiency Centre under his roof to promote energy conservation in the private sector. The Energy Efficiency Centre is a non-profit initiative that is offering energy auditing services to the industries. The centre is also supported by Nepal Energy Efficiency Programme of Deutsche Gesellschaft für Internationale Zusammenarbeit. A study conducted in 2012 found out that Nepalese industries could save 160,000-megawatt hours of electricity and 8,000 terajoules of thermal energy (like diesel, furnace oil, and coal) every year. These savings are equivalent to annual energy cost cut of up to 6.4 Billion Nepalese Rupees. As a result of Nepal Economic Forum 2014, an economic reform agenda in the priority sectors was declared focusing on energy conservation among others. In the energy reform agenda, the government of Nepal gave the commitment to introduce incentive packages in the budget of the fiscal year 2015/16 for industries that practices energy efficiency or use efficient technologies (incl. cogeneration). New Zealand In New Zealand the Energy Efficiency and Conservation Authority is the Government Agency responsible for promoting energy efficiency and conservation. The Energy Management Association of New Zealand is a membership-based organization representing the New Zealand energy services sector, providing training and accreditation services with the aim of ensuring energy management services are credible and dependable. Nigeria In Nigeria, the Lagos State Government is encouraging Lagosians to imbibe an energy conservation culture. In 2013, the Lagos State Electricity Board (LSEB) ran an initiative tagged "Conserve Energy, Save Money" under the Ministry of Energy and Mineral Resources. The initiative is designed to sensitize Lagosians around the theme of energy conservation by influencing their behavior through do-it-yourself tips. In September 2013, Governor Babatunde Raji Fashola of Lagos State and the campaign ambassador, rapper Jude "MI" Abaga participated in the Governor's conference video call on the topic of energy conservation. In addition to this, during the month of October (the official energy conservation month in the state), LSEB hosted experience centers in malls around Lagos State where members of the public were encouraged to calculate their household energy consumption and discover ways to save money using a consumer-focused energy app. To get Lagosians started on energy conservation, solar lamps and energy-saving bulbs were also handed out. In Kaduna State, the Kaduna Power Supply Company (KAPSCO) ran a program to replace all light bulbs in Public Offices; fitting energy-saving bulbs in place of incandescent bulbs. KAPSCO is also embarking on an initiative to retrofit all conventional streetlights in the Kaduna Metropolis to LEDs which consume much less energy. Sri Lanka Sri Lanka currently consumes fossil fuels, hydro power, wind power, solar power and dendro power for their day to day power generation. The Sri Lanka Sustainable Energy Authority is playing a major role regarding energy management and energy conservation. Today, most industries are requested to reduce their energy consumption by using renewable energy sources and optimizing their energy usage. Turkey Turkey aims to decrease by at least 20% the amount of energy consumed per GDP of Turkey by 2023 (energy intensity). United Kingdom The Department for Business, Energy and Industrial Strategy is responsible for promoting energy efficiency in the United Kingdom. United States The United States is currently the second-largest single consumer of energy, following China. The U.S. Department of Energy categorizes national energy use in four broad sectors: transportation, residential, commercial, and industrial. About half of U.S. energy consumption in the transportation and residential sectors is primarily controlled by individual consumers. In the typical American home, space heating is the most significant energy use, followed by electrical technology (appliances, lighting, and electronics) and water heating. Commercial and industrial energy expenditures are determined by businesses entities and other facility managers. National energy policy has a significant effect on energy usage across all four sectors. Since the oil embargoes and price spikes of the 1970s, energy efficiency and conservation have been fundamental tenets of U.S. energy policy. The scope of energy conservation and efficiency measures has been broadened throughout time by U.S. energy policies and programs, including federal and state legislation and regulatory actions, to include all economic sectors and all geographical areas of the nation. Measurable energy conservation and efficiency gains in the 1980s led to the 1987 Energy Security Report to the President (DOE, 1987) that "the United States uses about 29 quads less energy in a year today than it would have if our economic growth since 1972 had been accompanied by the less- efficient trends in energy use we were following at that time" The DOE Strategy and the legislation included new strategies for strengthening conservation and efficiency in buildings, industry, and electric power, such as integrated resource planning for electric and natural gas utilities and efficiency and labeling standards for 13 residential appliances and equipment categories. Lack of a national consensus on how to proceed interfered with developing a consistent and comprehensive approach. Nevertheless, the Energy Policy Act of 2005 (EPAct05; 109th U.S. Congress, 2005) contained many new energy conservation and efficiency provisions in the transportation, buildings, and electric power sectors. The most recent federal law to increase and broaden U.S. energy conservation and efficiency laws, programs, and practices is the Energy Independence and Security Act of 2007 (EISA). Over the next few decades, it is anticipated that EISA will significantly reduce energy use because it has more standards and targets than previous legislation. Both acts reinforce the importance of lighting and appliance efficiency programs, targeting an additional 70% lighting efficiency by 2020, introducing 45 new standards for appliances, and setting up new standards for vehicle fuel economy. The Federal Government is also promoting a new 30% model code for efficient building practices in the construction industry. Additionally, according to the American Council for an Energy-Efficient Economy (ACEEE), the EISA's energy efficiency and conservation initiatives will cut carbon dioxide emissions by 9% in 2030. These requirements cover appliance and lighting efficiency, energy savings in homes, businesses, and public buildings, the effectiveness of industrial manufacturing facilities, and the efficiency of electricity supply and end use. Expectations are high for increased energy savings due to these initiatives, which have already started contributing to new federal, state, and local laws, programs, and practices across the U.S. The development and use of alternative transportation fuels (whose supply is expected to expand by 15% by 2022), renewable energy sources, and other clean energy technologies have also received more attention and financial incentives. Recent policies also emphasize growing the use of coal with carbon capture and sequestration, solar, wind, nuclear, and other clean energy sources. In February 2023 the United States Department of Energy proposed a set of new energy efficiency standards that, if implemented, will save to users of different electric machines in the United States around $3,500,000,000 per year and will reduce by the year 2050 carbon emissions by the same amount as emitted by 29,000,000 houses. Mechanisms to promote conservation Governmental mechanisms Governments at the national, regional, and local levels may implement policies to promote energy efficiency. Building energy rules can cover the energy consumption of an entire structure or specific building components, like heating and cooling systems. They represent some of the most frequently used instruments for energy efficiency improvements in buildings and can play an essential role in improving energy conservation in buildings. There are multiple reasons for the growth of these policies and programs since the 2000s, including cost savings as energy prices increased, growing concern about the environmental impacts of energy use, and public health concerns. The policies and programs related to energy conservation are critical to establishing safety and performance levels, assisting in consumer decision-making, and explicitly identifying energy-conserving and energy-efficient products. Recent policies include new programs and regulatory incentives that call for electric and natural gas utilities to increase their involvement in delivering energy-efficiency products and services to their customers. For example, the National Action Plan for Energy Efficiency (NAPEE) is a public-private partnership created in response to EPAct05 that brings together senior executives from electric and natural gas utilities, state public utility commissions, other state agencies, and environmental and consumer groups representing every region of the country. The success of building energy regulation in effectively controlling energy consumption in the building sector will be, to a great extent, associated with the adopted energy performance indicator and the promoted energy assessment tools. It can help overcome significant market barriers and ensure cost-effective energy efficiency opportunities are incorporated into new buildings. This is crucial in emerging nations where new constructions are rapidly developing, and market and energy prices sometimes discourage efficient technologies. The building energy standards development and adoption showed that 42% of emerging developing countries surveyed have no energy standard in place, 20% have mandatory, 22% have mixed, and 16% proposed. The major impediments to implementing building energy regulations for energy conservation and efficiency in the building sector are institutional barriers and market failures rather than technical problems, as pointed out by Nature Publishing Group (2008). Among these, Santamouris (2005) includes a lack of owners' awareness of energy conservation benefits, building energy regulations benefits, insufficient awareness and training of property managers, builders, and engineers, and a lack of specialized professionals to ensure compliance. Based on the above information, the development and adoption of building energy regulations, such as energy standards in developing countries, are still far behind compared to building energy regulation adoption and implementation in developed countries. Building energy standards are starting to appear in Africa, Latin America, and Middle East regions, even though this is a new development going to the result obtained in this study. The level of progress on energy regulation activities in Africa, Latin America, and the Middle East is increasing, given the higher number of energy standard proposals recorded in these regions. According to the Royal Institute of Chartered Surveyors, several codes are being developed in developing countries with UNDP and GEF support. These typically include elemental and integrated routes to compliance, such as a fundamental method defining the performance requirements of specific building elements. However, they are still far behind in building energy regulation development, implementation, and compliance compared to developed nations. Also, decision-making regarding energy regulations is still from the government only, with little or no input from non-governmental entities. As a result, lower energy regulation development is recorded in these regions compared to regions with integrated and consensus approaches. Additionally, there is growing government involvement in the development and implementation of energy standards; 62% of Middle Eastern respondents, 45% of African respondents, and 43% of Latin American respondents indicated that existing government agencies, such as building agencies and energy agencies, are involved in implementing building energy standards in their respective nations, as opposed to 20% of European respondents, 38% of Asian respondents, and 0% of North American respondents, who indicated the involvement of existing agencies. Several North African nations, like Tunisia and Egypt, have programs relating to building energy standards, while Algeria and Morocco are now seeking to establish building energy standards, according to the Royal Institute of Chartered Surveyors. Similarly, Egypt's residential energy standard became law in 2005, and their commercial standard was anticipated to follow. The standards provide minimal performance requirements for applications involving air conditioners and other appliances and elemental and integrated pathways. However, it was claimed that enforcement legislation was still required in 2005. Additionally, Morocco launched a program in 2005 to create thermal energy requirements for construction, concentrating on the hospitality, healthcare, and communal housing industries. Mandatory energy standards Energy standards are the primary way governments foster energy efficiency as a public good. A recognized standard-setting organization prepares a standard. Standards developed by recognized organizations are often used as the basis for the development and updating of building codes. They allow innovative approaches and techniques to achieve effective energy use and optimum building performance. Besides, it encourages cost-effective energy use of building components, including building envelope, lighting, HVAC, electrical installations, lift and escalator, and other equipment. Energy-efficiency standards have been expanded and strengthened for appliances, building equipment, and lighting. For example, appliances and equipment standards are being developed for a new range of devices, including reduction goals for "standby" power that keeps consumer electronic products in a ready-to-use mode. Some devices require certain levels of energy performance from a car, building, appliance, or other technical equipment. If the vehicle, building, appliance, or equipment does not meet these standards, there may be restrictions on its sale or rent. In the U.K., these are called "minimum energy efficiency standards" or MEES and were applied to privately rented accommodation in 2019. Energy codes and standards are vital in setting minimum energy-efficient design and construction requirements. Buildings should be developed following energy standards to save energy efficiently. They specify uniform requirements for new buildings, additions, and modifications. National organizations like the American Society of Heating, Refrigerating, and Air-Conditioning Engineers publish the standards (ASHRAE). State and municipal governments frequently use energy standards as the technical foundation for creating their energy regulations. Some energy standards are written in a mandatory and enforceable language, making it simple for governments to add the standards' provisions directly to their laws or regulations. The American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) is a well-known example of a standard-making organization. This organization dates to the nineteenth century and is international in its membership (About ASHRAE 2018). Examples of ASHRAE standards that relate to energy conservation in the built environment are: Standard 62.1-2016 Ventilation for Acceptable Indoor Air Quality Standard 90.2-2007 Energy Efficient Design of Low-Rise Residential Buildings Standard 100-2018 Energy Efficiency in Existing Buildings Standard 189.1-2014 Standard for the Design of High-Performance Green Buildings The Residential Energy Services Network is a crucial benchmark for energy reduction (RESNET). The Home Energy Rating System (HERS) of RESNET, which is based on the International Code Council's (ICC) energy code, is used to rate home energy consumption with a standard numerical scale that examines factors in home energy use (About HERS 2018). The American National Standards Institute (ANSI) has acknowledged the HERS assessment system as a national benchmark for evaluating energy efficiency. The International Energy Conservation Code (IECC) of the ICC requires an energy rating index, and the main index used in the residential building sector is HERS. The mortgage financing sector makes substantial use of the HERS index. A home's expected energy usage may impact the available mortgage funds based on the HERS score, with more energy-efficient, lower energy-using homes potentially qualifying for a better mortgage rate or amount. Mandatory energy labels Many governments require that a car, building, or piece of equipment be labeled with its energy performance. This allows consumers and customers to see the energy implications of their choices, but does not restrict their choices or regulate which products are available to choose from. It also does not enable easily comparing options (such as being able to filter by energy-efficiency in online stores) or have the best energy-conserving options accessible (such as energy-conserving options being available in the frequented local store). (An analogy would be nutritional labeling on food.) A trial of estimated financial energy cost of refrigerators alongside EU energy-efficiency class (EEEC) labels online found that the approach of labels involves a trade-off between financial considerations and higher cost requirements in effort or time for the product-selection from the many available options which are often unlabelled and don't have any EEEC-requirement for being bought, used or sold within the EU. Moreover, in this one trial the labeling was ineffective in shifting purchases towards more sustainable options. Energy taxes Some countries employ energy or carbon taxes to motivate energy users to reduce their consumption. Carbon taxes can motivate consumption to shift to energy sources with fewer emissions of carbon dioxide, such as solar power, wind power, hydroelectricity or nuclear power while avoiding cars with combustion engines, jet fuel, oil, fossil gas and coal. On the other hand, taxes on all energy consumption can reduce energy use across the board while reducing a broader array of environmental consequences arising from energy production. The state of California employs a tiered energy tax whereby every consumer receives a baseline energy allowance that carries a low tax. As for usage increases above that baseline, the tax increases drastically. Such programs aim to protect poorer households while creating a larger tax burden for high energy consumers. Developing countries specifically are less likely to impose policy measures that slow carbon emissions as this would slow their economic development. These growing countries may be more likely to support their own economic growth and support their citizens rather than decreasing their carbon emissions. The following pros and cons of a carbon tax help one to see some of the potential effects of a carbon tax policy. Pros of Carbon Tax include: Making polluters pay the external cost of carbon emissions. Enables greater social efficiency as all citizens pay the full social cost. Raises revenue which can, in turn, be spent on mitigating the effects of pollution. Encourages firms and consumers to search for non-carbon producing alternatives (ex. solar power, wind power, hydroelectricity, or nuclear power). Reduces environmental costs associated with excess carbon pollution. Cons of Carbon Tax include: Businesses claim higher taxes which can discourage investment and economic growth. A carbon tax may encourage tax evasion as firms may pollute in secret to avoid a carbon tax. It may be difficult to measure external costs and how much the carbon tax should truly be. There are administration costs in measuring pollution and collecting the associated tax. Firms may move production to countries in which there is no carbon tax.

Qualitative research

Qualitative research is a type of research that aims to gather and analyse non-numerical (descriptive) data in order to gain an understanding of individuals' social reality, including understanding their attitudes, beliefs, and motivation. This type of research typically involves in-depth interviews, focus groups, or field observations in order to collect data that is rich in detail and context. Qualitative research is often used to explore complex phenomena or to gain insight into people's experiences and perspectives on a particular topic. It is particularly useful when researchers want to understand the meaning that people attach to their experiences or when they want to uncover the underlying reasons for people's behavior. Qualitative methods include ethnography, grounded theory, discourse analysis, and interpretative phenomenological analysis. Qualitative research methods have been used in sociology, anthropology, political science, psychology, communication studies, social work, folklore, educational research, information science and software engineering research. Background Qualitative research has been informed by several strands of philosophical thought and examines aspects of human life, including culture, expression, beliefs, morality, life stress, and imagination. Contemporary qualitative research has been influenced by a number of branches of philosophy, for example, positivism, postpositivism, critical theory, and constructivism. The historical transitions or 'moments' in qualitative research, together with the notion of 'paradigms' (Denzin & Lincoln, 2005), have received widespread popularity over the past decades. However, some scholars have argued that the adoptions of paradigms may be counterproductive and lead to less philosophically engaged communities. Approaches to inquiry The use of nonquantitative material as empirical data has been growing in many areas of the social sciences, including learning sciences, development psychology and cultural psychology. Several philosophical and psychological traditions have influenced investigators' approaches to qualitative research, including phenomenology, social constructionism, symbolic interactionism, and positivism. Philosophical traditions Phenomenology refers to the philosophical study of the structure of an individual's consciousness and general subjective experience. Approaches to qualitative research based on constructionism, such as grounded theory, pay attention to how the subjectivity of both the researcher and the study participants can affect the theory that develops out of the research. The symbolic interactionist approach to qualitative research examines how individuals and groups develop an understanding of the world. Traditional positivist approaches to qualitative research seek a more objective understanding of the social world. Qualitative researchers have also been influenced by the sociology of knowledge and the work of Alfred Schütz, Peter L. Berger, Thomas Luckmann, and Harold Garfinkel. Sources of data Qualitative researchers use different sources of data to understand the topic they are studying. These data sources include interview transcripts, videos of social interactions, notes, verbal reports and artifacts such as books or works of art. The case study method exemplifies qualitative researchers' preference for depth, detail, and context. Data triangulation is also a strategy used in qualitative research. Autoethnography, the study of self, is a qualitative research method in which the researcher uses his or her personal experience to understand an issue. Grounded theory is an inductive type of research, based on ("grounded" in) a very close look at the empirical observations a study yields. Thematic analysis involves analyzing patterns of meaning. Conversation analysis is primarily used to analyze spoken conversations. Biographical research is concerned with the reconstruction of life histories, based on biographical narratives and documents. Narrative inquiry studies the narratives that people use to describe their experience. Data collection Qualitative researchers may gather information through observations, note-taking, interviews, focus groups (group interviews), documents, images and artifacts. Interviews Research interviews are an important method of data collection in qualitative research. An interviewer is usually a professional or paid researcher, sometimes trained, who poses questions to the interviewee, in an alternating series of usually brief questions and answers, to elicit information. Compared to something like a written survey, qualitative interviews allow for a significantly higher degree of intimacy, with participants often revealing personal information to their interviewers in a real-time, face-to-face setting. As such, this technique can evoke an array of significant feelings and experiences within those being interviewed. Sociologists Bredal, Stefansen and Bjørnholt identified three "participant orientations", that they described as "telling for oneself", "telling for others" and "telling for the researcher". They also proposed that these orientations implied "different ethical contracts between the participant and researcher". Participant observation In participant observation ethnographers get to understand a culture by directly participating in the activities of the culture they study. Participant observation extends further than ethnography and into other fields, including psychology. For example, by training to be an EMT and becoming a participant observer in the lives of EMTs, Palmer studied how EMTs cope with the stress associated with some of the gruesome emergencies they deal with. Recursivity In qualitative research, the idea of recursivity refers to the emergent nature of research design. In contrast to standardized research methods, recursivity embodies the idea that the qualitative researcher can change a study's design during the data collection phase. Recursivity in qualitative research procedures contrasts to the methods used by scientists who conduct experiments. From the perspective of the scientist, data collection, data analysis, discussion of the data in the context of the research literature, and drawing conclusions should be each undertaken once (or at most a small number of times). In qualitative research however, data are collected repeatedly until one or more specific stopping conditions are met, reflecting a nonstatic attitude to the planning and design of research activities. An example of this dynamism might be when the qualitative researcher unexpectedly changes their research focus or design midway through a study, based on their first interim data analysis. The researcher can even make further unplanned changes based on another interim data analysis. Such an approach would not be permitted in an experiment. Qualitative researchers would argue that recursivity in developing the relevant evidence enables the researcher to be more open to unexpected results and emerging new constructs. Data analysis Qualitative researchers have a number of analytic strategies available to them. Coding In general, coding refers to the act of associating meaningful ideas with the data of interest. In the context of qualitative research, interpretative aspects of the coding process are often explicitly recognized and articulated; coding helps to produce specific words or short phrases believed to be useful abstractions from the data. Pattern thematic analysis Data may be sorted into patterns for thematic analyses as the primary basis for organizing and reporting the study findings. Content analysis According to Krippendorf, "Content analysis is a research technique for making replicable and valid inference from data to their context" (p. 21). It is applied to documents and written and oral communication. Content analysis is an important building block in the conceptual analysis of qualitative data. It is frequently used in sociology. For example, content analysis has been applied to research on such diverse aspects of human life as changes in perceptions of race over time, the lifestyles of contractors, and even reviews of automobiles. Issues Computer-assisted qualitative data analysis software (CAQDAS) Contemporary qualitative data analyses can be supported by computer programs (termed computer-assisted qualitative data analysis software). These programs have been employed with or without detailed hand coding or labeling. Such programs do not supplant the interpretive nature of coding. The programs are aimed at enhancing analysts' efficiency at applying, retrieving, and storing the codes generated from reading the data. Many programs enhance efficiency in editing and revising codes, which allow for more effective work sharing, peer review, data examination, and analysis of large datasets. Common qualitative data analysis software includes: ATLAS.ti Dedoose (mixed methods) MAXQDA (mixed methods) NVivo QDA MINER A criticism of quantitative coding approaches is that such coding sorts qualitative data into predefined (nomothetic) categories that are reflective of the categories found in objective science. The variety, richness, and individual characteristics of the qualitative data are reduced or, even, lost. To defend against the criticism that qualitative approaches to data are too subjective, qualitative researchers assert that by clearly articulating their definitions of the codes they use and linking those codes to the underlying data, they preserve some of the richness that might be lost if the results of their research boiled down to a list of predefined categories. Qualitative researchers also assert that their procedures are repeatable, which is an idea that is valued by quantitatively oriented researchers. Sometimes researchers rely on computers and their software to scan and reduce large amounts of qualitative data. At their most basic level, numerical coding schemes rely on counting words and phrases within a dataset; other techniques involve the analysis of phrases and exchanges in analyses of conversations. A computerized approach to data analysis can be used to aid content analysis, especially when there is a large corpus to unpack. Trustworthiness A central issue in qualitative research is trustworthiness (also known as credibility or, in quantitative studies, validity). There are many ways of establishing trustworthiness, including member check, interviewer corroboration, peer debriefing, prolonged engagement, negative case analysis, auditability, confirmability, bracketing, and balance. Data triangulation and eliciting examples of interviewee accounts are two of the most commonly used methods of establishing the trustworthiness of qualitative studies. Transferability of results has also been considered as an indicator of validity. Limitations of qualitative research Qualitative research is not without limitations. These limitations include participant reactivity, the potential for a qualitative investigator to over-identify with one or more study participants, "the impracticality of the Glaser-Strauss idea that hypotheses arise from data unsullied by prior expectations," the inadequacy of qualitative research for testing cause-effect hypotheses, and the Baconian character of qualitative research. Participant reactivity refers to the fact that people often behave differently when they know they are being observed. Over-identifying with participants refers to a sympathetic investigator studying a group of people and ascribing, more than is warranted, a virtue or some other characteristic to one or more participants. Compared to qualitative research, experimental research and certain types of nonexperimental research (e.g., prospective studies), although not perfect, are better means for drawing cause-effect conclusions. Glaser and Strauss, influential members of the qualitative research community, pioneered the idea that theoretically important categories and hypotheses can emerge "naturally" from the observations a qualitative researcher collects, provided that the researcher is not guided by preconceptions. The ethologist David Katz wrote "a hungry animal divides the environment into edible and inedible things....Generally speaking, objects change...according to the needs of the animal." Karl Popper carrying forward Katz's point wrote that "objects can be classified and can become similar or dissimilar, only in this way--by being related to needs and interests. This rule applied not only to animals but also to scientists." Popper made clear that observation is always selective, based on past research and the investigators' goals and motives and that preconceptionless research is impossible. The Baconian character of qualitative research refers to the idea that a qualitative researcher can collect enough observations such that categories and hypotheses will emerge from the data. Glaser and Strauss developed the idea of theoretical sampling by way of collecting observations until theoretical saturation is obtained and no additional observations are required to understand the character of the individuals under study. Bertrand Russell suggested that there can be no orderly arrangement of observations such that a hypothesis will jump out of those ordered observations; some provisional hypothesis usually guides the collection of observations. In psychology Community psychology Autobiographical narrative research has been conducted in the field of community psychology. A selection of autobiographical narratives of community psychologists can be found in the book Six Community Psychologists Tell Their Stories: History, Contexts, and Narrative. Educational psychology Edwin Farrell used qualitative methods to understand the social reality of at-risk high school students. Later he used similar methods to understand the reality of successful high school students who came from the same neighborhoods as the at-risk students he wrote about in his previously mentioned book. Health psychology In the field of health psychology, qualitative methods have become increasingly employed in research on understanding health and illness and how health and illness are socially constructed in everyday life. Since then, a broad range of qualitative methods have been adopted by health psychologists, including discourse analysis, thematic analysis, narrative analysis, and interpretative phenomenological analysis. In 2015, the journal Health Psychology published a special issue on qualitative research.<ref>Gough, B., & Deatrick, J.A. (eds.)(2015). Qualitative research in health psychology [special issue]. Health Psychology, 34 (4).</ref> Industrial and organizational psychology According to Doldor and colleagues organizational psychologists extensively use qualitative research "during the design and implementation of activities like organizational change, training needs analyses, strategic reviews, and employee development plans." Occupational health psychology Although research in the field of occupational health psychology (OHP) has predominantly been quantitatively oriented, some OHP researchers have employed qualitative methods. Qualitative research efforts, if directed properly, can provide advantages for quantitatively oriented OHP researchers. These advantages include help with (1) theory and hypothesis development, (2) item creation for surveys and interviews, (3) the discovery of stressors and coping strategies not previously identified, (4) interpreting difficult-to-interpret quantitative findings, (5) understanding why some stress-reduction interventions fail and others succeed, and (6) providing rich descriptions of the lived lives of people at work.Schonfeld, I. S., & Farrell, E. (2010). Qualitative methods can enrich quantitative research on occupational stress: An example from one occupational group. In D. C. Ganster & P. L. Perrewé (Eds.), Research in occupational stress and wellbeing series. Vol. 8. New developments in theoretical and conceptual approaches to job stress (pp. 137-197). Bingley, UK: Emerald. Some OHP investigators have united qualitative and quantitative methods within a single study (e.g., Elfering et al., [2005]); these investigators have used qualitative methods to assess job stressors that are difficult to ascertain using standard measures and well validated standardized instruments to assess coping behaviors and dependent variables such as mood. Social media psychology Since the advent of social media in the early 2000s, formerly private accounts of personal experiences have become widely shared with the public by millions of people around the world. Disclosures are often made openly, which has contributed to social media's key role in movements like the #metoo movement. The abundance of self-disclosure on social media has presented an unprecedented opportunity for qualitative and mixed methods researchers; mental health problems can now be investigated qualitatively more widely, at a lower cost, and with no intervention by the researchers. To take advantage of these data, researchers need to have mastered the tools for conducting qualitative research.

Homogeneity and heterogeneity

Homogeneity and heterogeneity are concepts relating to the uniformity of a substance, process or image. A homogeneous feature is uniform in composition or character (i.e. color, shape, size, weight, height, distribution, texture, language, income, disease, temperature, radioactivity, architectural design, etc.); one that is heterogeneous is distinctly nonuniform in at least one of these qualities. Etymology and spelling The words homogeneous and heterogeneous come from Medieval Latin homogeneus and heterogeneus, from Ancient Greek ὁμογενής (homogenēs) and ἑτερογενής (heterogenēs), from ὁμός (homos, "same") and ἕτερος (heteros, "other, another, different") respectively, followed by γένος (genos, "kind"); -ous is an adjectival suffix. Alternate spellings omitting the last -e- (and the associated pronunciations) are common, but mistaken: homogenous is strictly a biological/pathological term which has largely been replaced by homologous. But use of homogenous to mean homogeneous has seen a rise since 2000, enough for it to now be considered an "established variant". Similarly, heterogenous is a spelling traditionally reserved to biology and pathology, referring to the property of an object in the body having its origin outside the body. Scaling The concepts are the same to every level of complexity. From atoms to galaxies, plants, animals, humans, and other living organisms all share both a common or unique set of complexities. Hence, an element may be homogeneous on a larger scale, compared to being heterogeneous on a smaller scale. This is known as an effective medium approximation. Examples Various disciplines understand heterogeneity, or being heterogeneous, in different ways. Biology Environmental heterogeneity Environmental heterogeneity (EH) is a hypernym for different environmental factors that contribute to the diversity of species, like climate, topography, and land cover. Biodiversity is correlated with geodiversity on a global scale. Heterogeneity in geodiversity features and environmental variables are indicators of environmental heterogeneity. They drive biodiversity at local and regional scales. Scientific literature in ecology contains a big number of different terms for environmental heterogeneity, often undefined or conflicting in their meaning. and are a synonyms of environmental heterogeneity. Chemistry Homogeneous and heterogeneous mixtures In chemistry, a heterogeneous mixture consists of either or both of 1) multiple states of matter or 2) hydrophilic and hydrophobic substances in one mixture; an example of the latter would be a mixture of water, octane, and silicone grease. Heterogeneous solids, liquids, and gases may be made homogeneous by melting, stirring, or by allowing time to pass for diffusion to distribute the molecules evenly. For example, adding dye to water will create a heterogeneous solution at first, but will become homogeneous over time. Entropy allows for heterogeneous substances to become homogeneous over time. A heterogeneous mixture is a mixture of two or more compounds. Examples are: mixtures of sand and water or sand and iron filings, a conglomerate rock, water and oil, a salad, trail mix, and concrete (not cement). A mixture can be determined to be homogeneous when everything is settled and equal, and the liquid, gas, the object is one color or the same form. Various models have been proposed to model the concentrations in different phases. The phenomena to be considered are mass rates and reaction. Homogeneous and heterogeneous reactions Homogeneous reactions are chemical reactions in which the reactants and products are in the same phase, while heterogeneous reactions have reactants in two or more phases. Reactions that take place on the surface of a catalyst of a different phase are also heterogeneous. A reaction between two gases or two miscible liquids is homogeneous. A reaction between a gas and a liquid, a gas and a solid or a liquid and a solid is heterogeneous. Geology Earth is a heterogeneous substance in many aspects; for instance, rocks (geology) are inherently heterogeneous, usually occurring at the micro-scale and mini-scale. Linguistics In formal semantics, homogeneity is the phenomenon in which plural expressions imply "all" when asserted but "none" when negated. For example, the English sentence "Robin read the books" means that Robin read all the books, while "Robin didn't read the books" means that she read none of them. Neither sentence can be asserted if Robin read exactly half of the books. This is a puzzle because the negative sentence does not appear to be the classical negation of the sentence. A variety of explanations have been proposed including that natural language operates on a trivalent logic. Information technology With information technology, heterogeneous computing occurs in a network comprising different types of computers, potentially with vastly differing memory sizes, processing power and even basic underlying architecture. Mathematics and statistics In algebra, homogeneous polynomials have the same number of factors of a given kind. In the study of binary relations, a homogeneous relation R is on a single set (R ⊆ X × X) while a heterogeneous relation concerns possibly distinct sets (R ⊆ X × Y,  X = Y or X ≠ Y). In statistical meta-analysis, study heterogeneity is when multiple studies on an effect are measuring somewhat different effects due to differences in subject population, intervention, choice of analysis, experimental design, etc.; this can cause problems in attempts to summarize the meaning of the studies. Medicine In medicine and genetics, a genetic or allelic heterogeneous condition is one where the same disease or condition can be caused, or contributed to, by several factors, or in genetic terms, by varying or different genes or alleles. In cancer research, cancer cell heterogeneity is thought to be one of the underlying reasons that make treatment of cancer difficult. Physics In physics, "heterogeneous" is understood to mean "having physical properties that vary within the medium". Sociology In sociology, "heterogeneous" may refer to a society or group that includes individuals of differing ethnicities, cultural backgrounds, sexes, or ages. Diverse is the more common synonym in the context.

PEST analysis

In business analysis, PEST analysis (political, economic, social and technological) is a framework of external macro-environmental factors used in strategic management and market research. PEST analysis was developed in 1967 by Francis Aguilar as an environmental scanning framework for businesses to understand the external conditions and relations of a business in order to assist managers in strategic planning. It has also been termed ETPS analysis. PEST analyses give an overview of the different macro-environmental factors to be considered by a business, indicating market growth or decline, business position, as well as the potential of and direction for operations. Components The basic PEST analysis includes four factors: political, economic, social, and technological. Political Political factors relate to how the governments intervene in economies. Specifically, political factors comprise areas including tax policy, labour law, environmental law, trade restrictions, tariffs, and political stability. Other factors include what are considered merit goods and demerit goods by a government, and the impact of governments on health, education, and infrastructure of a nation. Economic Economic factors include economic growth, exchange rates, inflation rate, and interest rates. Social Social factors include cultural aspects and health consciousness, population growth rate, age distribution, career attitudes and safety emphasis. Trends in social factors affect the demand for a company's products and how that company operates. Through analysis of social factors, companies may adopt various management strategies to adapt to social trends. Technological Technological factors include R&D activity, automation, technology incentives and the rate of technological change. These can determine barriers to entry, minimum efficient production level and influence the outsourcing decisions. Technological shifts would also affect costs, quality, and innovation. Variants Many similar frameworks have been constructed, with the addition of other components such as environment and law. These include PESTLE, PMESII-PT, STEPE, STEEP, STEEPLE, STEER, and TELOS. Legal and regulatory Legal factors include discrimination law, consumer law, antitrust law, employment law, and health and safety law, which can affect how a company operates, its costs, and the demand for its products. Regulatory factors have also been analysed as its own pillar. Environment Environmental factors include ecological and environmental aspects such as weather, climate, and climate change, which may especially affect industries such as tourism, farming, and insurance. Environmental analyses often use the PESTLE framework, which allow for the evaluation of factors affecting management decisions for coastal zone and freshwater resources, development of sustainable buildings, sustainable energy solutions, and transportation. Demographic Demographic factors have been considered in frameworks such as STEEPLED. Factors include gender, age, ethnicity, knowledge of languages, disabilities, mobility, home ownership, employment status, religious belief or practice, culture and tradition, living standards and income level. Military Military analyses have used the PMESII-PT framework, which considers political, military, economic, social, information, infrastructure, physical environment and time aspects in a military context. Operational The TELOS framework explores technical, economic, legal, operational, and scheduling factors. Limitations PEST analysis can be helpful to explain market changes in the past, but it is not always suitable to predict or foresee upcoming market changes.

Misanthropy

Misanthropy is the general hatred, dislike, or distrust of the human species, human behavior, or human nature. A misanthrope or misanthropist is someone who holds such views or feelings. Misanthropy involves a negative evaluative attitude toward humanity that is based on humankind's flaws. Misanthropes hold that these flaws characterize all or at least the greater majority of human beings. They claim that there is no easy way to rectify them short of a complete transformation of the dominant way of life. Various types of misanthropy are distinguished in the academic literature based on what attitude is involved, at whom it is directed, and how it is expressed. Either emotions or theoretical judgments can serve as the foundation of the attitude. It can be directed toward all humans without exception or exclude a few idealized people. In this regard, some misanthropes condemn themselves while others consider themselves superior to everyone else. Misanthropy is sometimes associated with a destructive outlook aiming to hurt other people or an attempt to flee society. Other types of misanthropic stances include activism by trying to improve humanity, quietism in the form of resignation, and humor mocking the absurdity of the human condition. The negative misanthropic outlook is based on different types of human flaws. Moral flaws and unethical decisions are often seen as the foundational factor. They include cruelty, selfishness, injustice, greed, and indifference to the suffering of others. They may result in harm to humans and animals, such as genocides and factory farming of livestock. Other flaws include intellectual flaws, like dogmatism and cognitive biases, as well as aesthetic flaws concerning ugliness and lack of sensitivity to beauty. Many debates in the academic literature discuss whether misanthropy is a valid viewpoint and what its implications are. Proponents of misanthropy usually point to human flaws and the harm they have caused as a sufficient reason for condemning humanity. Critics have responded to this line of thought by claiming that severe flaws concern only a few extreme cases, like mentally ill perpetrators, but not humanity at large. Another objection is based on the claim that humans also have virtues besides their flaws and that a balanced evaluation might be overall positive. A further criticism rejects misanthropy because of its association with hatred, which may lead to violence, and because it may make people friendless and unhappy. Defenders of misanthropy have responded by claiming that this applies only to some forms of misanthropy but not to misanthropy in general. A related issue concerns the question of the psychological and social factors that cause people to become misanthropes. They include socio-economic inequality, living under an authoritarian regime, and undergoing personal disappointments in life. Misanthropy is relevant in various disciplines. It has been discussed and exemplified by philosophers throughout history, like Heraclitus, Diogenes, Thomas Hobbes, Jean-Jacques Rousseau, Arthur Schopenhauer, and Friedrich Nietzsche. Misanthropic outlooks form part of some religious teachings discussing the deep flaws of human beings, like the Christian doctrine of original sin. Misanthropic perspectives and characters are also found in literature and popular culture. They include William Shakespeare's portrayal of Timon of Athens, Molière's play The Misanthrope, and Gulliver's Travels by Jonathan Swift. Misanthropy is closely related to but not identical to philosophical pessimism. Some misanthropes promote antinatalism, the view that humans should abstain from procreation. Definition Misanthropy is traditionally defined as hatred or dislike of humankind. The word originated in the 17th century and has its roots in the Greek words μῖσος mīsos 'hatred' and ἄνθρωπος ānthropos 'man, human'. In contemporary philosophy, the term is usually understood in a wider sense as a negative evaluation of humanity as a whole based on humanity's vices and flaws. This negative evaluation can express itself in various forms, hatred being only one of them. In this sense, misanthropy has a cognitive component based on a negative assessment of humanity and is not just a blind rejection. Misanthropy is usually contrasted with philanthropy, which refers to the love of humankind and is linked to efforts to increase human well-being, for example, through good will, charitable aid, and donations. Both terms have a range of meanings and do not necessarily contradict each other. In this regard, the same person may be a misanthrope in one sense and a philanthrope in another sense. One central aspect of all forms of misanthropy is that their target is not local but ubiquitous. This means that the negative attitude is not just directed at some individual persons or groups but at humanity as a whole. In this regard, misanthropy is different from other forms of negative discriminatory attitudes directed at a particular group of people. This distinguishes it from the intolerance exemplified by misogynists, misandrists, and racists, which hold a negative attitude toward women, men, or certain races. According to literature theorist Andrew Gibson, misanthropy does not need to be universal in the sense that a person literally dislikes every human being. Instead, it depends on the person's horizon. For instance, a villager who loathes every other villager without exception is a misanthrope if their horizon is limited to only this village. Both misanthropes and their critics agree that negative features and failings are not equally distributed, i.e. that the vices and bad traits are exemplified much more strongly in some than in others. But for misanthropy, the negative assessment of humanity is not based on a few extreme and outstanding cases: it is a condemnation of humanity as a whole that is not just directed at exceptionally bad individuals but includes regular people as well. Because of this focus on the ordinary, it is sometimes held that these flaws are obvious and trivial but people may ignore them due to intellectual flaws. Some see the flaws as part of human nature as such. Others also base their view on non-essential flaws, i.e. what humanity has come to be. This includes flaws seen as symptoms of modern civilization in general. Nevertheless, both groups agree that the relevant flaws are "entrenched". This means that there is either no or no easy way to rectify them and nothing short of a complete transformation of the dominant way of life would be required if that is possible at all. Types Various types of misanthropy are distinguished in the academic literature. They are based on what attitude is involved, how it is expressed, and whether the misanthropes include themselves in their negative assessment. The differences between them often matter for assessing the arguments for and against misanthropy. An early categorization suggested by Immanuel Kant distinguishes between positive and negative misanthropes. Positive misanthropes are active enemies of humanity. They wish harm to other people and undertake attempts to hurt them in one form or another. Negative misanthropy, by contrast, is a form of peaceful anthropophobia that leads people to isolate themselves. They may wish others well despite seeing serious flaws in them and prefer to not involve themselves in the social context of humanity. Kant associates negative misanthropy with moral disappointment due to previous negative experiences with others. Another distinction focuses on whether the misanthropic condemnation of humanity is only directed at other people or at everyone including oneself. In this regard, self-inclusive misanthropes are consistent in their attitude by including themselves in their negative assessment. This type is contrasted with self-aggrandizing misanthropes, who either implicitly or explicitly exclude themselves from the general condemnation and see themselves instead as superior to everyone else. In this regard, it may be accompanied by an exaggerated sense of self-worth and self-importance. According to literature theorist Joseph Harris, the self-aggrandizing type is more common. He states that this outlook seems to undermine its own position by constituting a form of hypocrisy. A closely related categorization developed by Irving Babbitt distinguishes misanthropes based on whether they allow exceptions in their negative assessment. In this regard, misanthropes of the naked intellect regard humanity as a whole as hopeless. Tender misanthropes exclude a few idealized people from their negative evaluation. Babbitt cites Rousseau and his fondness for natural uncivilized man as an example of tender misanthropy and contrasts it with Jonathan Swift's thorough dismissal of all of humanity. A further way to categorize forms of misanthropy is in relation to the type of attitude involved toward humanity. In this regard, philosopher Toby Svoboda distinguishes the attitudes of dislike, hate, contempt, and judgment. A misanthrope based on dislike harbors a distaste in the form of negative feelings toward other people. Misanthropy focusing on hatred involves an intense form of dislike. It includes the additional component of wishing ill upon others and at times trying to realize this wish. In the case of contempt, the attitude is not based on feelings and emotions but on a more theoretical outlook. It leads misanthropes to see other people as worthless and look down on them while excluding themselves from this assessment. If the misanthropic attitude has its foundation in judgment, it is also theoretical but does not distinguish between self and others. It is the view that humanity is in general bad without implying that the misanthrope is in any way better than the rest. According to Svoboda, only misanthropy based on judgment constitutes a serious philosophical position. He holds that misanthropy focusing on contempt is biased against other people while misanthropy in the form of dislike and hate is difficult to assess since these emotional attitudes often do not respond to objective evidence. Misanthropic forms of life Misanthropy is usually not restricted to a theoretical opinion but involves an evaluative attitude that calls for a practical response. It can express itself in different forms of life. They come with different dominant emotions and practical consequences for how to lead one's life. These responses to misanthropy are sometimes presented through simplified archetypes that may be too crude to accurately capture the mental life of any single person. Instead, they aim to portray common attitudes among groups of misanthropes. The two responses most commonly linked to misanthropy involve either destruction or fleeing from society. The destructive misanthrope is said to be driven by a hatred of humankind and aims at tearing it down, with violence if necessary. For the fugitive misanthrope, fear is the dominant emotion and leads the misanthrope to seek a secluded place in order to avoid the corrupting contact with civilization and humanity as much as possible. The contemporary misanthropic literature has also identified further less-known types of misanthropic lifestyles. The activist misanthrope is driven by hope despite their negative appraisal of humanity. This hope is a form of meliorism based on the idea that it is possible and feasible for humanity to transform itself and the activist tries to realize this ideal. A weaker version of this approach is to try to improve the world incrementally to avoid some of the worst outcomes without the hope of fully solving the basic problem. Activist misanthropes differ from quietist misanthropes, who take a pessimistic approach toward what the person can do for bringing about a transformation or significant improvements. In contrast to the more drastic reactions of the other responses mentioned, they resign themselves to quiet acceptance and small-scale avoidance. A further approach is focused on humor based on mockery and ridicule at the absurdity of the human condition. An example is that humans hurt each other and risk future self-destruction for trivial concerns like a marginal increase in profit. This way, humor can act both as a mirror to portray the terrible truth of the situation and as its palliative at the same time. Forms of human flaws A core aspect of misanthropy is that its negative attitude toward humanity is based on human flaws. Various misanthropes have provided extensive lists of flaws, including cruelty, greed, selfishness, wastefulness, dogmatism, self-deception, and insensitivity to beauty. These flaws can be categorized in many ways. It is often held that moral flaws constitute the most serious case. Other flaws discussed in the contemporary literature include intellectual flaws, aesthetic flaws, and spiritual flaws. Moral flaws are usually understood as tendencies to violate moral norms or as mistaken attitudes toward what is the good. They include cruelty, indifference to the suffering of others, selfishness, moral laziness, cowardice, injustice, greed, and ingratitude. The harm done because of these flaws can be divided into three categories: harm done directly to humans, harm done directly to other animals, and harm done indirectly to both humans and other animals by harming the environment. Examples of these categories include the Holocaust, factory farming of livestock, and pollution causing climate change. In this regard, it is not just relevant that human beings cause these forms of harm but also that they are morally responsible for them. This is based on the idea that they can understand the consequences of their actions and could act differently. However, they decide not to, for example, because they ignore the long-term well-being of others in order to get short-term personal benefits. Intellectual flaws concern cognitive capacities. They can be defined as what leads to false beliefs, what obstructs knowledge, or what violates the demands of rationality. They include intellectual vices, like arrogance, wishful thinking, and dogmatism. Further examples are stupidity, gullibility, and cognitive biases, like the confirmation bias, the self-serving bias, the hindsight bias, and the anchoring bias. Intellectual flaws can work in tandem with all kinds of vices: they may deceive someone about having a vice. This prevents the affected person from addressing it and improving themselves, for instance, by being mindless and failing to recognize it. They also include forms of self-deceit, wilful ignorance, and being in denial about something. Similar considerations have prompted some traditions to see intellectual failings, like ignorance, as the root of all evil. Aesthetic flaws are usually not given the same importance as moral and intellectual flaws, but they also carry some weight for misanthropic considerations. These flaws relate to beauty and ugliness. They concern ugly aspects of human life itself, like defecation and aging. Other examples are ugliness caused by human activities, like pollution and litter, and inappropriate attitudes toward aesthetic aspects, like being insensitive to beauty. Causes Various psychological and social factors have been identified in the academic literature as possible causes of misanthropic sentiments. The individual factors by themselves may not be able to fully explain misanthropy but can show instead how it becomes more likely. For example, disappointments and disillusionments in life can cause a person to adopt a misanthropic outlook. In this regard, the more idealistic and optimistic the person initially was, the stronger this reversal and the following negative outlook tend to be. This type of psychological explanation is found as early as Plato's Phaedo. In it, Socrates considers a person who trusts and admires someone without knowing them sufficiently well. He argues that misanthropy may arise if it is discovered later that the admired person has serious flaws. In this case, the initial attitude is reversed and universalized to apply to all others, leading to general distrust and contempt toward other humans. Socrates argues that this becomes more likely if the admired person is a close friend and if it happens more than once. This form of misanthropy may be accompanied by a feeling of moral superiority in which the misanthrope considers themselves to be better than everyone else. Other types of negative personal experiences in life may have a similar effect. Andrew Gibson uses this line of thought to explain why some philosophers became misanthropes. He uses the example of Thomas Hobbes to explain how a politically unstable environment and the frequent wars can foster a misanthropic attitude. Regarding Arthur Schopenhauer, he states that being forced to flee one's home at an early age and never finding a place to call home afterward can have a similar effect. Another psychological factor concerns negative attitudes toward the human body, especially in the form of general revulsion from sexuality. Besides the psychological causes, some wider social circumstances may also play a role. Generally speaking, the more negative the circumstances are, the more likely misanthropy becomes. For instance, according to political scientist Eric M. Uslaner, socio-economic inequality in the form of unfair distribution of wealth increases the tendency to adopt a misanthropic perspective. This has to do with the fact that inequality tends to undermine trust in the government and others. Uslaner suggests that it may be possible to overcome or reduce this source of misanthropy by implementing policies that build trust and promote a more equal distribution of wealth. The political regime is another relevant factor. This specifically concerns authoritarian regimes using all means available to repress their population and stay in power. For example, it has been argued that the severe forms of repression of the Ancien Régime in the late 17th century made it more likely for people to adopt a misanthropic outlook because their freedom was denied. Democracy may have the opposite effect since it allows more personal freedom due to its more optimistic outlook on human nature. Empirical studies often use questions related to trust in other people to measure misanthropy. This concerns specifically whether the person believes that others would be fair and helpful. In an empirical study on misanthropy in American society, Tom W. Smith concludes that factors responsible for an increased misanthropic outlook are low socioeconomic status, being from racial and ethnic minorities, and having experienced recent negative events in one's life. In regard to religion, misanthropy is higher for people who do not attend church and for fundamentalists. Some factors seem to play no significant role, like gender, having undergone a divorce, and never having been married. Another study by Morris Rosenberg finds that misanthropy is linked to certain political outlooks. They include being skeptical about free speech and a tendency to support authoritarian policies. This concerns, for example, tendencies to suppress political and religious liberties. Arguments Various discussions in the academic literature concern the question of whether misanthropy is an accurate assessment of humanity and what the consequences of adopting it are. Many proponents of misanthropy focus on human flaws together with examples of when they exercise their negative influences. They argue that these flaws are so severe that misanthropy is an appropriate response. Special importance in this regard is usually given to moral faults. This is based on the idea that humans do not merely cause a great deal of suffering and destruction but are also morally responsible for them. The reason is that they are intelligent enough to understand the consequences of their actions and could potentially make balanced long-term decisions instead of focusing on personal short-term gains. Proponents of misanthropy sometimes focus on extreme individual manifestations of human flaws, like mass killings ordered by dictators. Others emphasize that the problem is not limited to a few cases, for example, that many ordinary people are complicit in their manifestation by supporting the political leaders committing them. A closely related argument is to claim that the underlying flaws are there in everyone, even if they reach their most extreme manifestation only in a few. Another approach is to focus not on the grand extreme cases but on the ordinary small-scale manifestations of human flaws in everyday life, such as lying, cheating, breaking promises, and being ungrateful. Some arguments for misanthropy focus not only on general tendencies but on actual damage caused by humans in the past. This concerns, for instance, damages done to the ecosystem, like ecological catastrophes resulting in mass extinctions. Criticism Various theorists have criticized misanthropy. Some opponents acknowledge that there are extreme individual manifestations of human flaws, like mentally ill perpetrators, but claim that these cases do not reflect humanity at large and cannot justify the misanthropic attitude. For instance, while there are cases of extreme human brutality, like the mass killings committed by dictators and their forces, listing such cases is not sufficient for condemning humanity at large. Some critics of misanthropy acknowledge that humans have various flaws but state that they present just one side of humanity while evaluative attitudes should take all sides into account. This line of thought is based on the idea that humans possess equally important virtues that make up for their shortcomings. For example, accounts that focus only on the great wars, cruelties, and tragedies in human history ignore its positive achievements in the sciences, arts, and humanities. Another explanation given by critics is that the negative assessment should not be directed at humanity but at some social forces. These forces can include capitalism, racism, religious fundamentalism, or imperialism. Supporters of this argument would adopt an opposition to one of these social forces rather than a misanthropic opposition to humanity. Some objections to misanthropy are based not on whether this attitude appropriately reflects the negative value of humanity but on the costs of accepting such a position. The costs can affect both the individual misanthrope and the society at large. This is especially relevant if misanthropy is linked to hatred, which may turn easily into violence against social institutions and other humans and may result in harm. Misanthropy may also deprive the person of most pleasures by making them miserable and friendless. Another form of criticism focuses more on the theoretical level and claims that misanthropy is an inconsistent and self-contradictory position. An example of this inconsistency is the misanthrope's tendency to denounce the social world while still being engaged in it and being unable to fully leave it behind. This criticism applies specifically to misanthropes who exclude themselves from the negative evaluation and look down on others with contempt from an arrogant position of inflated ego but it may not apply to all types of misanthropy. A closely related objection is based on the claim that misanthropy is an unnatural attitude and should therefore be seen as an aberration or a pathological case. In various disciplines History of philosophy Misanthropy has been discussed and exemplified by philosophers throughout history. One of the earliest cases was the pre-Socratic philosopher Heraclitus. He is often characterized as a solitary person who is not fond of social interactions with others. A central factor to his negative outlook on human beings was their lack of comprehension of the true nature of reality. This concerns especially cases in which they remain in a state of ignorance despite having received a thorough explanation of the issue in question. Another early discussion is found in Plato's Phaedo, where misanthropy is characterized as the result of frustrated expectations and excessively naïve optimism. Various reflections on misanthropy are also found in the cynic school of philosophy. There it is argued, for instance, that humans keep on reproducing and multiplying the evils they are attempting to flee. An example given by the first-century philosopher Dio Chrysostom is that humans move to cities to defend themselves against outsiders but this process thwarts their initial goal by leading to even more violence due to high crime rates within the city. Diogenes is a well-known cynic misanthrope. He saw other people as hypocritical and superficial. He openly rejected all kinds of societal norms and values, often provoking others by consciously breaking conventions and behaving rudely. Thomas Hobbes is an example of misanthropy in early modern philosophy. His negative outlook on humanity is reflected in many of his works. For him, humans are egoistic and violent: they act according to their self-interest and are willing to pursue their goals at the expense of others. In their natural state, this leads to a never-ending war in which "every man to every man ... is an enemy". He saw the establishment of an authoritative state characterized by the strict enforcement of laws to maintain order as the only way to tame the violent human nature and avoid perpetual war. A further type of misanthropy is found in Jean-Jacques Rousseau. He idealizes the harmony and simplicity found in nature and contrasts them with the confusion and disorder found in humanity, especially in the form of society and institutions. For instance, he claims that "Man is born free; and everywhere he is in chains". This negative outlook was also reflected in his lifestyle: he lived solitary and preferred to be with plants rather than humans. Arthur Schopenhauer is often mentioned as a prime example of misanthropy. According to him, everything in the world, including humans and their activities, is an expression of one underlying will. This will is blind, which causes it to continuously engage in futile struggles. On the level of human life, this "presents itself as a continual deception" since it is driven by pointless desires. They are mostly egoistic and often result in injustice and suffering to others. Once they are satisfied, they only give rise to new pointless desires and more suffering. In this regard, Schopenhauer dismisses most things that are typically considered precious or meaningful in human life, like romantic love, individuality, and liberty. He holds that the best response to the human condition is a form of asceticism by denying the expression of the will. This is only found in rare humans and "the dull majority of men" does not live up to this ideal. Friedrich Nietzsche, who was strongly influenced by Schopenhauer, is also often cited as an example of misanthropy. He saw man as a decadent and "sick animal" that shows no progress over other animals. He even expressed a negative attitude toward apes since they are more similar to human beings than other animals, for example, with regard to cruelty. For Nietzsche, a noteworthy flaw of human beings is their tendency to create and enforce systems of moral rules that favor weak people and suppress true greatness. He held that the human being is something to be overcome and used the term Übermensch to describe an ideal individual who has transcended traditional moral and societal norms. Religion Some misanthropic views are also found in religious teachings. In Christianity, for instance, this is linked to the sinful nature of humans and the widespread manifestation of sin in everyday life. Common forms of sin are discussed in terms of the seven deadly sins. Examples are an excessive sense of self-importance in the form of pride and strong sexual cravings constituting lust. They also include the tendency to follow greed for material possessions as well as being envious of the possessions of others. According to the doctrine of original sin, this flaw is found in every human being since the doctrine states that human nature is already tainted by sin from birth by inheriting it from Adam and Eve's rebellion against God's authority. John Calvin's theology of Total depravity has been described by some theologians as misanthropic. Misanthropic perspectives can also be discerned in various Buddhist teachings. For example, Buddha had a negative outlook on the widespread flaws of human beings, including lust, hatred, delusion, sorrow, and despair. These flaws are identified with some form of craving or attachment (taṇhā) and cause suffering (dukkha). Buddhists hold that it is possible to overcome these failings in the process of achieving Buddhahood or enlightenment due to an innate Buddha nature. However, this is seen as a rare achievement in one lifetime in some of the Indian traditions whereas within East Asian Mahayana Chan, Zen and Pureland practice's it is achievable to become suddenly enlightened in one life time , In contrast to Indian Buddhist's doctrine regard that most human beings carry these deep flaws with them throughout their lives and to the next through the law of karma. However, there are also many religious teachings opposed to misanthropy, such as the emphasis on kindness and helping others. In Christianity, this is found in the concept of agape, which involves selfless and unconditional love in the form of compassion and a willingness to help others. Buddhists see the practice of loving kindness (metta) as a central aspect that implies a positive intention of compassion and the expression of kindness toward all sentient beings. Literature and popular culture Many examples of misanthropy are also found in literature and popular culture. Timon of Athens by William Shakespeare is a famous portrayal of the life of the Ancient Greek Timon, who is widely known for his extreme misanthropic attitude. Shakespeare depicts him as a wealthy and generous gentleman. However, he becomes disillusioned with his ungrateful friends and humanity at large. This way, his initial philanthropy turns into an unrestrained hatred of humanity, which prompts him to leave society in order to live in a forest. Molière's play The Misanthrope is another famous example. Its protagonist, Alceste, has a low opinion of the people around him. He tends to focus on their flaws and openly criticizes them for their superficiality, insincerity, and hypocrisy. He rejects most social conventions and thereby often offends others, for example, by refusing to engage in social niceties like polite small talk. The author Jonathan Swift had a reputation for being misanthropic. In some statements, he openly declares that he hates and detests "that animal called man". Misanthropy is also found in many of his works. An example is Gulliver's Travels, which tells the adventures of the protagonist Gulliver, who journeys to various places, like an island inhabited by tiny people and a land ruled by intelligent horses. Through these experiences of the contrast between humans and other species, he comes to see more and more the deep flaws of humanity, leading him to develop a revulsion toward other human beings. Ebenezer Scrooge from Charles Dickens's A Christmas Carol is an often-cited example of misanthropy. He is described as a cold-hearted, solitary miser who detests Christmas. He is greedy, selfish, and has no regard for the well-being of others. Other writers associated with misanthropy include Gustave Flaubert and Philip Larkin. The Joker from the DC Universe is an example of misanthropy in popular culture. He is one of the main antagonists of Batman and acts as an agent of chaos. He believes that people are selfish, cruel, irrational, and hypocritical. He is usually portrayed as a sociopath with a twisted sense of humor who uses violent means to expose and bring down organized society. Related concepts Philosophical pessimism Misanthropy is closely related but not identical to philosophical pessimism. Philosophical pessimism is the view that life is not worth living or that the world is a bad place, for example, because it is meaningless and full of suffering. This view is exemplified by Arthur Schopenhauer and Philipp Mainländer. Philosophical pessimism is often accompanied by misanthropy if the proponent holds that humanity is also bad and partially responsible for the negative value of the world. However, the two views do not require each other and can be held separately. A non-misanthropic pessimist may hold, for instance, that humans are just victims of a terrible world but not to blame for it. Eco-misanthropists, by contrast, may claim that the world and its nature are valuable but that humanity exerts a negative and destructive influence. Antinatalism and human extinction Antinatalism is the view that coming into existence is bad and that humans have a duty to abstain from procreation. A central argument for antinatalism is called the misanthropic argument. It sees the deep flaws of humans and their tendency to cause harm as a reason for avoiding the creation of more humans. These harms include wars, genocides, factory farming, and damages done to the environment. This argument contrasts with philanthropic arguments, which focus on the future suffering of the human about to come into existence. They argue that the only way to avoid their future suffering is to prevent them from being born. The Voluntary Human Extinction Movement and the Church of Euthanasia are well-known examples of social movements in favor of antinatalism and human extinction. Antinatalism is commonly endorsed by misanthropic thinkers but there are also many other ways that could lead to the extinction of the human species. This field is still relatively speculative but various suggestions have been made about threats to the long-term survival of the human species, like nuclear wars, self-replicating nanorobots, or super-pathogens. Such cases are usually seen as terrible scenarios and dangerous threats but misanthropes may instead interpret them as reasons for hope because the abhorrent age of humanity in history may soon come to an end. A similar sentiment is expressed by Bertrand Russell. He states in relation to the existence of human life on earth and its misdeeds that they are "a passing nightmare; in time the earth will become again incapable of supporting life, and peace will return." Human exceptionalism and deep ecology Human exceptionalism is the claim that human beings have unique importance and are exceptional compared to all other species. It is often based on the claim that they stand out because of their special capacities, like intelligence, rationality, and autonomy. In religious contexts, it is frequently explained in relation to a unique role that God foresaw for them or that they were created in God's image. Human exceptionalism is usually combined with the claim that human well-being matters more than the well-being of other species. This line of thought can be used to draw various ethical conclusions. One is the claim that humans have the right to rule the planet and impose their will on other species. Another is that inflicting harm on other species may be morally acceptable if it is done with the purpose of promoting human well-being and excellence. Generally speaking, the position of human exceptionalism is at odds with misanthropy in relation to the value of humanity. But this is not necessarily the case and it may be possible to hold both positions at the same time. One way to do this is to claim that humanity is exceptional because of a few rare individuals but that the average person is bad. Another approach is to hold that human beings are exceptional in a negative sense: given their destructive and harmful history, they are much worse than any other species. Theorists in the field of deep ecology are also often critical of human exceptionalism and tend to favor a misanthropic perspective. Deep ecology is a philosophical and social movement that stresses the inherent value of nature and advocates a radical change in human behavior toward nature. Various theorists have criticized deep ecology based on the claim that it is misanthropic by privileging other species over humans. For example, the deep ecology movement Earth First! faced severe criticism when they praised the AIDS epidemic in Africa as a solution to the problem of human overpopulation in their newsletter.

Environmental policy

Environmental policy is the commitment of an organization or government to the laws, regulations, and other policy mechanisms concerning environmental issues. These issues generally include air and water pollution, waste management, ecosystem management, maintenance of biodiversity, the management of natural resources, wildlife and endangered species. For example, concerning environmental policy, the implementation of an eco-energy-oriented policy at a global level to address the issues of global warming and climate changes could be addressed. Policies concerning energy or regulation of toxic substances including pesticides and many types of industrial waste are part of the topic of environmental policy. This policy can be deliberately taken to influence human activities and thereby prevent undesirable effects on the biophysical environment and natural resources, as well as to make sure that changes in the environment do not have unacceptable effects on humans. Definition One way is to describe environmental policy is that it comprises two major terms: environment and policy. Environment refers to the physical ecosystems, but can also take into consideration the social dimension (quality of life, health) and an economic dimension (resource management, biodiversity). Policy can be defined as a "course of action or principle adopted or proposed by a government, party, business or individual". Thus, environmental policy tends to focus on problems arising from human impact on the environment, which is important to human society by having a (negative) impact on human values. Such human values are often labeled as good health or the 'clean and green' environment. In practice, policy analysts provide a wide variety of types of information to the public decision-making process. The concept of environmental policy was first used in the 1960s to recognise that all environmental problems, like the environment itself, are interconnected. Addressing environmental problems effectively (such as air, water, and soil pollution) requires looking at their connections and underlying and common sources, and how policies addressing particular problems can have spill-over effects on other problems and policies. "The environment" thus became a focus for public policy and environmental policy the term to refer to the way environmental issues were addressed more or less comprehensively. Environmental issues typically addressed by environmental policy include (but are not limited to) air and water pollution, waste management, ecosystem management, biodiversity protection, the protection of natural resources, wildlife and endangered species, and the management of these natural resources for future generations. Relatively recently, environmental policy has also attended to the communication of environmental issues. Environmental policies often address issues in one of three dimensions of the environment: ecological (for instance, policies aimed at protecting a particular species or natural areas), resource (for instance, related to energy, land, water), and the human environment (the environment modified or shaped by humans, for instance, urban planning, pollution). Environmental policy-making is often highly fragmented, although environmental policy analysts have long pointed out the need for the development of more comprehensive and integrated environmental policies. In contrast to environmental policy, ecological policy addresses issues that focus on achieving benefits (both monetary and non monetary) from the non human ecological world. Broadly included in ecological policy is natural resource management (fisheries, forestry, wildlife, range, biodiversity, and at-risk species). This specialized area of policy possesses its own distinctive features. History As pointed out by environmental historians, environmental problems have long afflicted human societies and led to collective efforts to address these problems. Some longstanding problems have been the hunting of animals to extinction, soil erosion and salinisation (because of over-irrigation), and the adverse effects of some practices on human health (wood fires, unhygienic practices). In some cases, these practices contributed to the collapse of societies. In the 19th century, the growing impact of human development and practices on the environment became increasingly apparent. Deforestation, the decline and extinction of birds, the decline of aesthetics in landscapes and cities, large-scale mining (notably of coal), industrial pollution, and urban squalor led to growing awareness and appreciation of the importance of nature. Some seminal thinkers on these matters were George Perkins Marsh, Henry David Thoreau, and John Muir. In Europe, a positive view of nature was promoted by the Romanticist movement of poets, authors and artists from the early 18th century, a movement that lamented the despoliation of nature by industrialism. Building on these early forms of concern about nature, organisations aimed at the preservation of forests, birds and landscapes emerged in the United States, the United Kingdom, Europe, Australia and New Zealand in the late 19th and the early 20th centuries, these efforts, combined with concerns about dwindling timber supplies, were instrumental in the establishment of the first nature reserves, national and forest parks and to changes in forestry laws. Concerns about pollution and its threat to humans as well as nature has provided another major stimulus for the development of environmental policies. In 1863, in the United Kingdom, health problems arising from the release of harmful chemicals led to the adoption of the Alkali Act and the creation of the Alkali Inspectorate. In 1956, the Clean Air Act 1956 was adopted in the wake of London's Great Smog of 1952 that is believed to have killed 12,000 people. Concerns about the effects of pollution fuelled notably by the publication, in 1962, of Rachel Carson's Silent Spring, sparked the beginning of the modern environmental movement. It also marked the start of "the environment" becoming a concern of public policy, as pointed out by Caldwell in 1963. These growing concerns, as well as the growing publicity about environmental problems and accidents, forced governments to introduce or strengthen laws and policies aimed at enhancing environmental protection. Earth Day founder Gaylord Nelson, then a U.S. Senator from Wisconsin, after witnessing the ravages of the 1969 massive oil spill in Santa Barbara, California, became famous for his environmental work. Administrator Ruckelshaus was confirmed by the Senate on December 2, 1970, which is the traditional date used as the birth of the United States Environmental Protection Agency (EPA). Five months earlier, in July 1970, President Nixon had signed Reorganization Plan No. 3 calling for the establishment of EPA. At the time, environmental policy was a bipartisan issue and the efforts of the United States of America made it an early environmental leader. During this period, legislation was passed to regulate pollutants that go into the air, water tables, and solid waste disposal. President Nixon signed the Clean Air Act in 1970. In many countries, governments created environment ministries, departments or agencies, and appointed ministers of or for the environment. The world's first minister of the environment was the British Politician Peter Walker from the Conservative Party in 1970. In the European Union, the very first Environmental Action Programme was adopted by national government representatives in July 1973 during the first meeting of the Council of Environmental Ministers. Since then an increasingly dense network of legislation has developed, which now extends to all areas of environmental protection including air pollution control, water protection and waste policy but also nature conservation and the control of chemicals, biotechnology and other industrial risks. EU environmental policy has thus become a core area of European politics. Despite commonalities between countries in the development of environmental policies and institutions, they have also adopted different approaches in this area. In the 1970s, the field of Comparative Environmental Politics and Policy emerged to compare the environmental policies and institutions of countries aimed at explaining differences and similarities. Some of the pioneers in this area were Lennart Lundqvist and Cynthia Enloe. Rationale As documented by environmental historians, human societies have always impacted their environment, often with adverse consequences for themselves and the rest of nature. Their failure to (timely) recognise and address these problems has been a contributing factor to their decline and collapse. Although particular environmental problems like soil erosion, growing resource scarcity, air and water pollution increasingly became the subject of concern and government regulation in the 19th century, these were seen and addressed as separate issues. The shortcomings of this reactive and fragmented approach received growing recognition during the 1960s and early 1970s, the first wave of environmentalism. This was reflected in the creation, in many countries, of environmental agencies, policies and legislation with the aim of taking a more comprehensive and integrated approach to environmental issues. In 1972, the need for this was also recognised at the international level at the United Nations Conference on the Human Environment, which led to the creation of the United Nations Environment Programme. Thus, growing environmental awareness and concern provided the main rationale for the adoption of environmental policies and institutions by governments. Environmental protection became a focus of public policy. This rationale for environmental policy is broader than that provided by some interpretations based on economic theories. The rationale for governmental involvement in the environment is often attributed to market failure in the form of forces beyond the control of one person, including the free rider problem and the tragedy of the commons. An example of an externality is when a factory produces waste pollution which may be discharged into a river, ultimately contaminating water. The cost of such action is paid by society at large when they must clean the water before drinking it and is external to the costs of the polluter. The free rider problem occurs when the private marginal cost of taking action to protect the environment is greater than the private marginal benefit, but the social marginal cost is less than the social marginal benefit. The tragedy of the commons is the condition that, because no one person owns the commons, each individual has an incentive to utilize common resources as much as possible. Without governmental involvement, the commons is overused. Examples of tragedies of the commons are overfishing and overgrazing. The "market failure" rationale for environmental policy has been criticised for its implicit assumptions about the drivers of human behaviour, which are considered to be rooted in the idea that societies are nothing but collections of self-interested "utility-maximising" individuals. As Elinor Ostrom has demonstrated, this is not supported by evidence on how societies actually make resource decisions. The market-failure theory also assumes that "markets" have, or should have precedence over governments in collective decision-making, which is an ideological position that was challenged by Karl Polanyi whose historical analysis shows how the idea of a self-regulating market was politically created. He added that "Such an institution could not exist for any length of time without annihilating the human and natural substance of society." By contrast, ecological economists argue that economic policies should be developed within a theoretical framework that recognises the biophysical reality. The economic system is a sub-system of the biophysical environmental system on which humans and other species depend for their well-being and survival. The need for grounding environmental policy on ecological principles has also been recognised by many environmental policy analysts, sometimes under the label of ecological rationality and/or environmental integration. From this perspective, political, economic, and other systems, as well as policies, need to be "greened" to make them ecologically rational. Environmental policy approaches: instruments, problems, and issues In practice, governments have adopted a wide range of approaches to the development and implementation of environmental policies. To a large extent, differences in approaches have been influenced and shaped by the particular political, economic and social context of a country or polity (like the European Union or the United Nations). The differences in approaches, the reasons behind them, and their results have been the subject of research in the fields of comparative environmental politics and policy. But the study of problems and issues associated with environmental policy development has also been influenced by general public policy theories and analyses. Contributions on this front have been influenced by different academic disciplines, notably economics, public policy, and environmental studies, but also by political-ideological views, politics, and economic interests, among others through "think tanks". Thus, the design of environmental policy and the choice of policy instruments is always political and not just a matter determined by technical and efficiency considerations advanced by scientists, economists or other experts. As Majone has argued: "Policy instruments are seldom ideologically neutral" and "cannot be neatly separated from goals." The choice of policy instruments always occurs in a political context. Differences in ideological preferences of governments and political actors, and in national policy styles, have been argued to strongly influence a government's approach to policy design, including the choice of instruments. Although many different policy instruments can be identified, and many ways of classifying them have been put forward, very broadly, a minimalist approach distinguishes three kinds or categories of policy instruments: regulation, economic instruments, and normative or "hortatory" approaches. These have also been referred to as "sticks, carrots and sermons". Vedung, based on Majone's classification of power, argues that the main difference underlying these categories is the degree of coercion (authoritative force) involved. Regulation has been a traditional and predominant approach to policymaking in many policy areas and countries. It relies foremost on adopting rules (often backed up by legislation), to prohibit, impose or circumscribe human behaviour and practices. In the environmental policy area, this includes, for instance, the imposition of limits or standards for air and water pollution, car emissions, the regulation or banning of the use of hazardous substances, the phasing out of ozone-depleting substances, waste disposal, and laws to protect endangered species and natural areas. Regulation is often derogatorily referred to by detractors as a top-down, "command and control" approach as it leaves target groups with little if any control over the way(s) environmental activities or goals must be pursued. Since the 1980s, with the rise of neoliberalism in many countries and the associated redefinition of the role of the state (centred on the notion of governance rather than government), regulation has been touted as ineffective and inefficient, sparking a move toward deregulation and the adoption by many governments of "new" policy instruments, notably market instruments and voluntary agreements, also in the realm of environmental policy. Economic instruments involve the imposition or use of economic incentives, including (environmental) taxes, tax exemptions, fees, subsidies, and the creation of markets and rights for trading in substances, pollutants, resources, or activities, such as for SO2, CO2 (carbon or greenhouse gas emissions), water, and tradeable fisheries quota. They are based on the assumption that behaviour and practices are foremost driven by rationality, self-interest and economic considerations and that these motivations can be harnessed for environmental purposes. Decision-making studies cast doubt on these premises. Often, decisions are reached based on irrational influences, unconscious biases, illogical assumptions, and the desire to avoid or create ambiguity and uncertainty. Market-based policy instruments also have their supporters and detractors. Among the detractors, for example, some environmentalists contend that a more radical, overarching approach is needed than a set of specific initiatives, to deal with climate change. For example, energy efficiency measures may actually increase energy consumption in the absence of a cap on fossil fuel use, as people might drive more fuel-efficient cars. To combat this result, Aubrey Meyer calls for a 'framework-based market' of Contraction and Convergence. The Cap and Share and the Sky Trust are proposals based on the idea. In the case of corporations, it is assumed that such tools make it financially rewarding to engage in efficient environmental management that also improves business and organizational performance They also encourage businesses to become more transparent about their environmental performance by publishing data and reporting. For economic instruments to function, some form(s) of regulation are needed that involve policy design, for instance, related to the choice and level of taxation, who pays, who qualifies for rights or permits, and the rules on which trading, and a "market" depend for their functioning. For example, the implementation of greener public purchasing programs relies on a combination of regulation and economic incentives. Normative ("hortatory") instruments ("sermons") rely on persuasion and information. They include, among others, campaigns aimed at raising public awareness and enhancing knowledge of environmental problems, calls upon people to change their behaviour and practices (like taking up recycling, reducing waste, the use of water and energy, and using public transport), and voluntary agreements between governments and businesses. They share the aim of encouraging people to do "the right thing", to change their behaviour and practices, and to accept individual or group responsibility for addressing issues. Agreements between the government and private firms and commitments made by firms independent of government requirements are examples of voluntary environmental measures. Environmental Impact Assessment is a tool that relies foremost on the gathering of knowledge and information about (potential) environmental effects. It originated in the United States but has been adopted in many countries to analyse and assess the potential impacts of projects. Usually undertaken by experts, it is based on the assumption that an objective assessment of effects is possible, and that the knowledge generated will persuade decision-makers to make changes to proposals to mitigate or prevent adverse environmental effects. How EIA rules and processes are designed and implemented depends on regulation and is influenced by the political context. Eccleston and March argue that although policymakers normally have access to reasonably accurate environmental information, political and economic factors are important and often lead to policy decisions that rank environmental priorities of secondary importance.[Reference needed] The effectiveness of hortatory instruments has also been under debate. Policies relying foremost on such instruments may amount to little more than symbolic policies, implying that governments have little or no intention to effectively address an issue while creating the impression of taking it seriously. Such policies rely more on rhetoric than action. In the environmental realm, sustainable development policies or strategies are often used for this purpose if these are not translated into clear and specific objectives, timeframes and measures. Yet, hortatory policy instruments are often preferred by governments and other actors as they are seen as a way of recognising and sharing collective responsibility, possibly avoiding the need for regulation and/or economic instruments. They are thus often used as a first step towards addressing environmental problems. However, these tools are often combined with some form of legislation and regulation, for instance, in the case of labelling of consumer products (product information), waste disposal and recycling. There has been much debate about the relative merits of the various kinds of policy instruments. Market instruments are often held up and used as a more efficient and cost-effective, alternative to regulation. Yet, many analysts have pointed out that regulation, economic incentives, "market" instruments, and environmental taxation and subsidies can achieve the same results. For instance, as Kemp and Pontoglio argue, policy instruments cannot be usefully ranked with regard to their effects on eco-innovation, "the often expressed view that market-based approaches such as pollution taxes and emission trading systems are better for promoting eco-innovation is not brought out by the case study literature or by survey analysis", and there is actually more evidence that regulations stimulate radical innovation more than market-based instruments. It has also been argued that If the government can anticipate new technology or is able to react to it optimally, regulatory policies by virtue of administered prices (taxes) and policies by setting quantities (issuing tradable permits) are (almost) equivalent. More generally, the performance of economic instruments in dealing with environmental problems has been a mixed bag, referred to by Hahn as "not very impressive", and has led Tietenberg to conclude that they are "no panacea". Different instruments are sometimes combined in a policy mix to address a particular environmental problem. Since environmental issues have many aspects, several policy instruments may be required to adequately address each one. Ideally, government policies are carefully formulated so that the individual measures do not undermine one another or create a rigid and cost-ineffective framework. Overlapping policies result in unnecessary administrative costs, increasing the cost of implementation. To help governments realize their policy goals, the OECD Environment Directorate, for example, collects data on the efficiency and consequences of environmental policies implemented by the national governments. Their website provides a database detailing countries' experiences with their environmental policies. The United Nations Economic Commission for Europe, through UNECE, and the OECD's Environmental Performance Reviews, evaluate progress made by its member countries in improving their environmental policies. However, although regulation, taxation and market instruments can be equally (in-) effective, they may differ significantly in the allocation and distribution of (potential) costs and benefits, with the allocation of tradeable ("property") rights potentially generating significant profits to those who receive such rights. They are, therefore, generally much preferred by affected resource users and industries, which explains their popularity since the rise of neoliberalism. This has led analysts to point out that there are many other important aspects to the choice of policy instruments than their efficiency and cost-effectiveness, such as distributional, ethical and political aspects, and their appropriateness for addressing environmental problems. Environmental policy analysis How environmental policies are made, how effective they are, and how they can or should be improved, has become the subject of considerable research and debate. In the academic realm, these questions are commonly addressed under the label of environmental policy analysis. Environmental policy analysis is a broad field comprising different approaches to explaining and developing environmental policy. The first type has been referred to in the policy literature as the analysis of policy and the second as the analysis for policy. Many approaches are derived from the broader field of public policy analysis which emerged as a scientific enterprise after WWII. While policy analysis as a decision-making tool continued to be applied in the business sector, the study of public policy, defined broadly as "What governments do, why they do it, and what difference it makes, became an important strand in political science. This variety, which has been classified into analycentric, policy process, and meta-policy categories, has also manifested itself in the area of environmental policy analysis which developed since the 1960s. The analycentric or rational approach The analycentric approach to environmental policy analysis, which focuses on particular issues and uses mostly quantitative methods to identify "optimal" (cost-effective or efficient) solutions, has been the prevalent way to address environmental problems, both by governments and businesses. It is also often depicted as the rational or scientific approach to and for policy development. While scientific analyses and (preferably) quantitative data provide knowledge of the more immediate sources or causes of environmental problems, such as forms of pollution and climate change, policy prescriptions are based on setting goals, objectives and targets and the identification of the most cost-effective and efficient means by assessing alternative options. Technological innovation, more efficient management, and economic instruments such as cost-benefit analysis, environmental taxes, and tradeable permit schemes (market creation) have been among the preferred means in this approach. The analycentric or rational approach has been critiqued on various grounds. First, it assumes that there is adequate knowledge and agreement on the causes of problems and the goals to be achieved. Second, the approach (for policy) ignores the way policies are developed in (political) practice. Third, the preferred means are often based on questionable assumptions notably about human behaviour. Many of the limitations of the rational approach were already acknowledged by an early proponent, Herbert Simon, who argued that "limited rationality" provided a more realistic basis for decision-making. This view has also been expressed by advocates of more comprehensive and integrated environmental policy development, who argued that looking at problems in isolation (on a one-by-one basis) ignores the linkages between environmental problems and their causes. In the late 1980s, "green planning" and the adoption of sustainable development strategies, in particular, received support in academic circles and among many governments as rational, goal-based policy approaches aimed at overcoming the limitations of the fragmented analycentric approach. The policy process approach The policy process approach emphasises the role and importance of politics and power in policy development. It aims foremost at better understanding how policies are made and put into practice. It commonly involves identifying a variable number of steps, including problem definition and agenda setting, the formulation and selection of policy options, implementation, and evaluation. These are conceived as being parts of a policy cycle, as existing policies are reviewed and changed for political reasons and/or because they are deemed to be unsatisfactory. The various stages have become the focus of much research, generating insights into why and how policies have been developed and implemented, with variable outcomes and effectiveness. These studies show that policy development is more about the role of and interplay between conflicting interests than the result of rational analysis and finding and adopting (optimal) solutions to problems. One of the main schools of thought on this front is that of incrementalism, which argues that policy change often occurs in small steps that accommodate conflicting interests. Policy process analysis has also been applied to environmental policy in its different stages. It has been used, for instance, to clarify why environmental issues have had difficulty reaching or staying on the public and political agendas. More recently, research has revealed the role and power of businesses, notably the oil industry, in downplaying the risks associated with climate change or "climate denial." "Think tanks" and the media have been used to sow scepticism about the science behind environmental and other problems, to redefine issues, and to avert policies that threaten the interests of businesses. Policy process analyses also include studies of the variety of actors and their influence on government decision-making. Although pluralism, the idea that not one group dominates all decision-making in modern societies, has long been the prevailing school of thought in political science, it has been contested by elite theories that assign predominant power to elites in different areas or sectors of decision-making. To what extent environmental groups have had influence on government decisions and policies continues to be a subject of debate. Some argue that Non-Governmental organizations have the greatest influence on environmental policies. These days, many countries are facing huge environmental, social, and economic impacts of rapid population growth, development, and natural resource constraints. As NGOs try to help countries to tackle these issues more successfully, a lack of understanding about their role in civil society and the public perception that the government alone is responsible for the well-being of its citizens and residents makes NGOs tasks more difficult to achieve. NGOs such as Greenpeace and World Wildlife Fund can help tackling issues by conducting research to facilitate policy development, building institutional capacity, and facilitating independent dialogue with civil society to help people live more sustainable lifestyles. The need for a legal framework to recognize NGOs and enable them to access more diverse funding sources, high-level support/endorsement from local figureheads, and engaging NGOs in policy development and implementation is more important as environmental issues continue to increase. It has been argued that notwithstanding Reagan's efforts to undo environmental regulation in the US, the effects have been limited as environmental interests were already strongly entrenched. Under President Trump, again, many environmental regulations have been dismantled or were scheduled to be rolled back. Other research suggests that many environmental policies adopted by governments are designed to be weak and largely ineffective as business interests use their power to influence or even shape these policies, also at the international level. International organizations have also made great impacts on environmental policies by creating programmes such as the United Nations Environment Programme and hosting conferences such as the United Nations Earth Summit to address environmental issues. UNEP is the leading global environmental authority tasked with policy guidance for environmental programs. The UNEP monitors environmental aspects, such as waste management, energy use, greenhouse gas inventory, and water use to promote environmental sustainability and address environmental issues. The role of science and scientists in policy environmental policy development has been another focus of research. Scientists have been instrumental in discovering many environmental problems, from the damaging effects of the use of pesticides, the depletion of the ozone layer, the greenhouse effect, and all kinds of pollution, among others. In this respect, they have often provided legitimacy and support to the raising of concerns by the environmental movement, although they have often been reluctant to get involved in environmental activism out of fear of compromising their scientific credibility. Nonetheless, scientists have played a significant role pushing environmental issues onto the international agenda, together with international ENGOs, in what have been referred to as "epistemic communities." However, to what extent science can be "value-free" has been a subject of debate. Science and scientists always operate in a political-economic context that circumscribes their role, research and its effects. This raises the question of scientific integrity, especially when scientists are paid to serve commercial and political interests. The meta-policy approach Meta-policy research focuses on the ways policy development is influenced or shaped by contextual factors, including political institutions and systems, socio-cultural patterns, economic systems, knowledge frameworks, discourses, and the changes therein. The latter may involve deliberate changes to the formal and non-formal institutions through which policy analysis, development, decision-making, and implementation occur, such as the introduction of rules for cost-benefit analysis, risk analysis, consultation and accountability requirements, and organisational change. How environmental problems are interpreted and defined directly affects the development of environmental policies, at all stages of the policy cycle, from problem recognition, and the formulation of policy options, to decision-making, implementation and policy evaluation. However, much (meta-policy) research has been undertaken on what influences or shapes these views and interpretations. For instance, there is a large body of research that looks at whether societies have moved or are moving towards "post-materialist" values, or to a New Environmental Paradigm. More broadly, the link between dominant worldviews and the way the environment is treated has been a focus of much debate. The rise and growing support for the environmental movement is often seen as a driver towards "greener" societies. If such socio-cultural trends hold, this is expected to lead governments to adopt stronger environmental policies. Other meta-policy research focuses on the different "environmental discourses" and how they compete for dominance in societies and worldwide. The power to influence or shape people's view of the world has been referred to as "cognitive power". The role of intellectuals, opinion leaders, and the media in shaping and advancing the dominant views and ideologies in societies has been an important focus of Marxist and critical theory that has also influenced the analysis of environmental policy formation. Ownership and control of the media play an important role in the formation of public opinion on environmental issues. Other meta-policy research relevant to the development of environmental policy focuses on institutional and systemic factors. For instance, the role of environmental institutions and their capacity and power within the broader systems of government is found to be an important factor in advancing or constraining environmental policy. More broadly, the question of whether capitalism is compatible or not with long-term environmental protection has been a subject of debate. As, after the collapse of the Soviet Union and the introduction of capitalism in China, capitalism became a globally dominant system, this question has become even more important to the future development of environmental policy at the national and international levels. As many analysts of global environmental politics have pointed out, the institutions for developing effective environmental policy at that level are weak and rather ineffective, as demonstrated by accounts of continuing environmental deterioration. Environmental policy evaluation Differences in approaches to environmental policy development and design, including the selection of policy instruments, linked to different historical, political-economic and socio-cultural contexts, and the inevitable role and influence of different cognitive and ideological frameworks in the analysis and design of policies, all make that evaluating environmental policies is also a complex and controversial matter. As many policy analysts have pointed out, judging the merits of policies goes beyond an assessment of the efficiency and cost-effectiveness of the policy instruments used. In the realm of public policy, policy evaluation is a topic that is seen as much more encompassing and complex. Apart from efficiency and cost-effectiveness, many other important aspects of policy and criteria for evaluating them have been identified and discussed, including their knowledge (science) basis, their goals and objectives, ethical issues, distributional effects, and process and legitimacy. Although efforts have been made to put evaluation on its own (trans-) disciplinary footing as a systematic and independent stage in the policy process, either before the adoption of policies (ex-ante evaluation) or after their implementation (ex-post evaluation) this remains fraught with problems. In practice, systematic evaluation remains a largely neglected aspect or stage of policymaking, in large part, because of the political nature and sensitivity of evaluating government's policies. The difficulties of policy evaluation also apply to environmental policies. Also there, policy evaluation is often approached in simple terms based on the extent to which the stated goals of a policy have been achieved or not ("success or failure"). However, as many environmental policy analysts have pointed out, many other aspects of environmental policy are important. These include the goals and objectives of the policies (which may be deemed too vague, inadequate, poorly or wrongly targeted), their distributional effects (whether they contribute to or reduce environmental and social injustice), the kind of instruments used (for instance, their ethical and political dimensions), the processes by which policies have been developed (public participation and deliberation), and the extent to which they are institutionally supported. Moreover, as many environmental thinkers and policy analysts have pointed out, addressing environmental problems effectively requires an integrated approach. As the environment is an integrated whole or system, environmental policies need to take account of the interactions within that system and the effects of human actions and interventions not just on a problem in isolation, but also their (potential) effects of other problems. More often than not, fragmented policies and "solutions", for instance, to combat pollution, lead to the displacement of environmental problems or the generation of new ones. The interconnectedness of the environmental challenge, it has been said, requires an approach that is "ecological rational" and environmentally effective. This holistic way of thinking has been picked up and developed under a variety of labels, including Holistic Resource Management, Integrated Environmental Management, Ecosystems Management, and the notion of Environmental Integration. Environmental integration, in broad terms, is "the integration of environmental considerations into all areas of human thinking, behaviour and practices that (potentially) affect the environment." This involves, among others, the development and adoption of an overarching view of the environment, an overarching policy to guide the "greening" of policies, and an institutional framework that gives "teeth" to environmental integration. In academic and government circles (notably the EU), much of the focus has been on environmental policy integration (EPI), the process of integrating environmental objectives into non-environmental policy areas, such as energy, agriculture and transport, rather than leaving them to be pursued solely through "purely" environmental policies. This is often particularly challenging because of the need to reconcile global objectives and international rules with domestic needs and laws. EPI is widely recognised as one of the key elements of sustainable development, and it was adopted as a formal requirement by the EU. More recently, the notion of "climate policy integration", also denoted as "mainstreaming", has been applied to indicate the integration of climate considerations (both mitigation and adaptation) into the broader (often economically focused) activities of government. Although, in the late 1980s and early 1990s, many governments began to adopt a more comprehensive approach to environmental issues, notably in the form of National Sustainable Development Strategies and "Green Planning", these efforts were largely abandoned during the 1990s due to the rise to prominence of neoliberal thinking, policies and reforms. This development led to the return of the fragmented and reactive approach to environmental problems with an emphasis on climate change and the use of "market-based" instruments. The field of Comparative Environment Policy and Politics aims to explain the differences in performance related to, among others, differences in political systems, institutions, policy styles and cultures. However, the environmental performance of governments remains commonly based on achievements in a range of environmental problems and policy outputs, as measured by separate indicators like CO2 emissions, different forms of air pollution, water quality indicators, and biological diversity (individual species). These assessments are often used as a basis for ranking the environmental performance of countries, with some characterised as leaders and others as laggards. However, such rankings have been treated with scepticism, not only on methodological grounds but especially because they mean little in terms of the extent to which governments take environmental integration seriously. While it has been noted that, at different stages, some countries have been leaders in some areas of environmental integration, these efforts have not been sustained over time. Ultimately, the environmental effectiveness of policies is measured by the extent to which they reduce or resolve environmental problems (ecological destruction and degradation, resource degradation and depletion, and adverse effects on humans by environmental modification, including by urban development and pollution). Whether environmental policies have addressed environmental problems more or less effectively remains a topic of debate. On the one hand, some take a very positive and optimistic view, arguing that, on many fronts, the environmental situation, especially as it affects humans, has improved. On the other hand, many scientists and scientific reports paint a bleak picture of where the world is going, based on deteriorating environmental indicators linked to global heating, declining biodiversity, pollution trends (including of new forms of pollution such as the spread of plastic nanoparticles), and ongoing resource degradation and decline (such as water and agricultural land). Improving environmental policy Reflecting the diversity of approaches to environmental policy development, influenced by contextual factors, policy perspectives, and political-ideological views, among others, there are also different views on how environmental policy could or should be improved. The three most common standpoints have been referred to as incrementalism ("tinkering"), democratisation, and systemic change. Incrementalism has been deemed to be the most common (standard) way governments change their policies with the stated aim of improving them. Propagated in particular by Charles Lindblom based on his view of American political reality, he argued that changing policies in small steps is not only the most common way policies are developed, but also the best way, as it avoids making big errors that could result from a "rational-comprehensive" approach. Also, over time, a series of small changes may add up and bring about significant and big change. Although incrementalism has been critiqued for its underlying assumptions and conservative implications ("tinkering"), and also for its failure to come to grips with environmental problems, it is a very recognisable approach to policy "improvement" in many countries. As incrementalism does not question the political-economic status quo, its suggestions for policy improvement are foremost of a managerial or technological kind. Tinkering with policy and management tools, and technological innovation, are seen as the main and most desirable ("win-win") ways to address environmental (and other) problems. This "technocentric" approach, which is seen as politically neutral, has been a preferred and dominant approach to "solving" environmental problems from the beginning of the environmental era, advocated by governments, businesses, and many environmentalists. The managerial approach also involves training "environmental practitioners" and policy analysts. Given the growing need for trained environmental practitioners, graduate schools throughout the world offer specialized professional degrees in environmental policy studies. While there is not a standard curriculum, students typically take classes in policy analysis, environmental science, environmental law and politics, ecology, energy, and natural resource management. Graduates of these programs are employed by governments, international organizations, private sector, think tanks, advocacy organizations, and universities. Much of the research and innovation sponsored by governments, businesses and international organisations under the heading of "transition management" is aimed at the gradual (incremental) development of new "transformative" technologies, for instance, in areas like energy, transport and agriculture. An example is the European environmental research and innovation policy, which aims at defining and implementing a transformative agenda to greening the economy and society as a whole so as to achieve "truly" sustainable development. The EU strategies, actions and programmes promote more and better research and innovation for building a resource-efficient, climate-resilient society and thriving economy which are meant to be in sync with the natural environment. Research and innovation in Europe are financially supported by the programme Horizon 2020, which is also open to participation worldwide. Yet, the "transition management" approach to sustainability has been critiqued for its a-political, technocratic and elitist nature. Also, Bucchi argues that the traditional technocentric approach no longer suffices as science has increasingly been commercialised and politicised and lost much of its image of neutrality that it enjoyed with the public at large. In line with the policy process perspective, many environmental advocates and analysts support improving the opportunities for public participation and input in the policy process, as well as increasing transparency. The policy design literature aims to pull together insights gained from studies of the various stages of the policy cycle to design more effective policies, to better consider the tools, rules and assumptions on which they are based, the groups at which they are targeted, contextual factors, as well as the nature (complexity) of the problem. Enhancing public input and participation is argued to have the potential to improve all stages of the policy cycle, including problem definition, decision-making, policy implementation, and evaluation. UNFCCC research shows that climate-related projects and policies that involve women are more effective. Policies, projects and investments without meaningful participation by women are less effective and often increase existing gender inequalities. Women found climate solutions that cross political or ethnic boundaries have been particularly important in regions where entire ecosystems are under threat, e.g. small island states, the Arctic and the Amazon and in areas where people's livelihoods depend on natural resources e.g. fishing, farming and forestry. However, the degree and kind of opportunities provided for public input and deliberation are seen as a key factor, both for improving the effectiveness of policies and for enhancing their support basis and legitimacy. Enhancing democracy, for instance, by adopting forms of "discursive designs" and other forms of "reflexive" deliberative democracy, aims to create a level playing field on which citizens' representatives have a more equal chance to partake in shaping policy. Relatively recently, "citizens' assemblies" have been used in a range of countries to address controversial topics, including climate change policy. However, as these are temporary and advisory bodies, governments are not bound by their recommendations. Over time, many governments have introduced laws to provide public access to government-held information, for instance, by the adoption of Freedom of Information legislation. Although a growing number of governments have adopted such legislation, a report by Privacy International notes that in many countries much work remains to be done on the implementation front and the creation of a culture, "leaving access largely unfulfilled." A third approach to improving environmental policy is based on the view that meaningful progress on resolving environmental problems requires fundamental or systemic change, in particular of the prevailing socio-cultural, political and economic systems. Three categories of factors are commonly identified: cognitive factors (the way(s) environmental problems have been interpreted (cognitive factors), linked to dominant belief and value systems; political factors (the nature of the prevailing political systems); and the nature of the prevailing economic systems. These three types of factors are not mutually exclusive, and analysts often combine them to provide more comprehensive explanations. That the way environmental problems predominantly are interpreted is a fundamental obstacle to addressing the environmental challenge effectively, has been pointed out already from the earliest stages of the rise of environmental awareness and thinking. Many early environmental thinkers argued that environmental problems are interrelated, finding their roots in the interconnectedness of the environment itself and the failure of human societies to recognise that reality and to heed this in their behaviour and practices. These thinkers point out the need to take a "holistic", ecosystems or integrated approach to the management of the environment and the use of resources. Often, it is argued that such an approach was common to indigenous societies, but that this got pushed aside and lost with the rise of "modernity" and rational-analytic (scientific) thinking. In modern societies, nature has come to be seen, analysed and manipulated as a machine in the service of human ends. But as the way the environmental challenge is interpreted is closely linked to the dominant socio-cultural (value) system, the latter is also said to need fundamental change. There is a large body of literature on the role and importance of the dominant values in societies and the (possible) changes therein, among others linked to economic development, urbanisation and globalisation. On the one hand, analysts have identified the rise of individualism, materialism, consumerism, and the decline of community values in modern societies and cultures. On the other hand, some analysts, notably based on Ronald Inglehart's work, argue that, with rising standards of living, comes a shift in societies, facilitated by generational change, from material to "post-material" values, including self-actualisation, belonging, and aesthetics. However, it is debatable to what extent this shift represents a move towards environmental values becoming dominant and whether the level of support for the environment depends on a high standard of living. Others, notably inspired by Riley Dunlap's research, more directly explore whether the presently dominant paradigm is being replaced by what is referred to as the "New Environmental Paradigm". As yet, however, the findings of this research are inconclusive, although there is evidence that environmental concern and support have grown globally. Whether and how the dominant value systems and views on the environment can be purposefully changed by concerted social action aimed at assigning greater priority remains a matter of debate and uncertainty. On the one hand, the environmental movement has been touted as a "vanguard" in shifting the dominant paradigm. On the other hand, the effectiveness of the environmental movement in bringing about fundamental value change can and has been drawn into doubt. One reason is that the environmental movement itself is very diverse in views on the kind of value change(s) required, ranging from technocentric to deep ecological stances. To what extent green parties have been effective in changing dominant value patterns or are themselves subject to being co-opted by dominant values and interests is also subject to debate. To a large extent, as many analysts have pointed out, the ability to shape the dominant values and public views on the environment depends on the relative (cognitive) power held and exercised by groups, notably through control over the media and other institutions such as education, universities, think tanks, and the social media. The importance of the nature of political systems for the development of environmental (and other) policies has been the subject of much research, including in the field of Comparative Environmental Policy. Analysts have pointed out a broad range of factors that stand in the way of environmental issues being adequately recognised and/or assigned political priority, including the role, privileged access, power and influence, and even dominance of (non-environmental) interest groups, bureaucratic thinking and interests, the lack of openness and transparency, (very) limited opportunities for public input and participation, and the short political horizon linked to electoral cycles. Many of these factors are not confined to liberal-democratic political systems but also play a role, perhaps even more so, in authoritarian political systems. These political obstacles have generally led to a relative weakness in the power of government institutions (organisations and rules) advocating for environmental interests compared to non-environmental institutions and the circumscription of the power, role and influence of societal environmental groups, including green parties, if not their co-optation by the dominant powers and vested interests. This also affects the "environmental capacity" of political systems, severely limiting efforts to develop more comprehensive and integrated approaches to the environmental challenge. Other analysts emphasise the importance of economic systems, notably capitalism, as a fundamental obstacle to developing and adopting effective environmental policies. Some take the view that capitalism is fundamentally incompatible with long-term environmental protection, notably because of its inherent growth imperative. Others recognise this imperative as a problem but argue that it is possible to reform capitalism in a way that does not require growth, or that enables "green growth" based on the recognition of environmental limits. Many have pointed out that socialist economic systems have had even worse environmental records than capitalist systems, implying that socialism is no better alternative for the environment even apart from other considerations. However, this view is contested by those who argue that socialism as an economic system does not necessarily require an authoritarian system and that there is scope for creating democratic socialist systems that assign greater priority to collective interests, including environmental protection. These cognitive, social, political and economic factors are often referred to as systemic, meaning that overcoming these obstacles requires systemic, fundamental or transformative change, notably of the systems that are the sources and drivers of environmental pressures and problems, including the political and economic systems, and sectors like agriculture, energy, and transport. Increasingly, the tweaking of environmental and other policies is seen as inadequate, and there is growing recognition of the need for "transformative change". However, the interrelatedness of these systems raises questions about whether and/or how such transformative change can be achieved, which has led a growing number of environmental analysts, including scientists, to serious doubts and pessimism, although others argue that it remains possible for societies to do so.

Autonomy

In developmental psychology and moral, political, and bioethical philosophy, autonomy is the capacity to make an informed, uncoerced decision. Autonomous organizations or institutions are independent or self-governing. Autonomy can also be defined from a human resources perspective, where it denotes a (relatively high) level of discretion granted to an employee in his or her work. In such cases, autonomy is known to generally increase job satisfaction. Self-actualized individuals are thought to operate autonomously of external expectations. In a medical context, respect for a patient's personal autonomy is considered one of many fundamental ethical principles in medicine. Sociology In the sociology of knowledge, a controversy over the boundaries of autonomy inhibited analysis of any concept beyond relative autonomy, until a typology of autonomy was created and developed within science and technology studies[citation needed]. According to it, the institution of science's existing autonomy is "reflexive autonomy": actors and structures within the scientific field are able to translate or to reflect diverse themes presented by social and political fields, as well as influence them regarding the thematic choices on research projects. Institutional autonomy Institutional autonomy is having the capacity as a legislator to be able to implant and pursue official goals. Autonomous institutions are responsible for finding sufficient resources or modifying their plans, programs, courses, responsibilities, and services accordingly. But in doing so, they must contend with any obstacles that can occur, such as social pressure against cut-backs or socioeconomic difficulties. From a legislator's point of view, to increase institutional autonomy, conditions of self-management and institutional self-governance must be put in place. An increase in leadership and a redistribution of decision-making responsibilities would be beneficial to the research of resources. Institutional autonomy was often seen as a synonym for self-determination, and many governments feared that it would lead institutions to an irredentist or secessionist region. But autonomy should be seen as a solution to self-determination struggles. Self-determination is a movement toward independence, whereas autonomy is a way to accommodate the distinct regions/groups within a country. Institutional autonomy can diffuse conflicts regarding minorities and ethnic groups in a society. Allowing more autonomy to groups and institutions helps create diplomatic relationships between them and the central government. Politics In governmental parlance, autonomy refers to self-governance. An example of an autonomous jurisdiction was the former United States governance of the Philippine Islands. The Philippine Autonomy Act of 1916 provided the framework for the creation of an autonomous government under which the Filipino people had broader domestic autonomy than previously, although it reserved certain privileges to the United States to protect its sovereign rights and interests. Other examples include Kosovo (as the Socialist Autonomous Province of Kosovo) under the former Yugoslav government of Marshal Tito and Puntland Autonomous Region within Federal Republic of Somalia. Although often being territorially defined as self-governments, autonomous self-governing institutions may take a non-territorial form. Such non-territorial solutions are, for example, cultural autonomy in Estonia and Hungary, national minority councils in Serbia or Sámi parliaments in Nordic countries. Philosophy Autonomy is a key concept that has a broad impact on different fields of philosophy. In metaphysical philosophy, the concept of autonomy is referenced in discussions about free will, fatalism, determinism, and agency. In moral philosophy, autonomy refers to subjecting oneself to objective moral law. According to Kant Immanuel Kant (1724–1804) defined autonomy by three themes regarding contemporary ethics. Firstly, autonomy as the right for one to make their own decisions excluding any interference from others. Secondly, autonomy as the capacity to make such decisions through one's own independence of mind and after personal reflection. Thirdly, as an ideal way of living life autonomously. In summary, autonomy is the moral right one possesses, or the capacity we have in order to think and make decisions for oneself providing some degree of control or power over the events that unfold within one's everyday life. The context in which Kant addresses autonomy is in regards to moral theory, asking both foundational and abstract questions. He believed that in order for there to be morality, there must be autonomy. "Autonomous" is derived from the Greek word autonomos where 'auto' means self and 'nomos' means to govern (nomos: as can be seen in its usage in nomárchēs which means chief of the province). Kantian autonomy also provides a sense of rational autonomy, simply meaning one rationally possesses the motivation to govern their own life. Rational autonomy entails making your own decisions but it cannot be done solely in isolation. Cooperative rational interactions are required to both develop and exercise our ability to live in a world with others. Kant argued that morality presupposes this autonomy in moral agents, since moral requirements are expressed in categorical imperatives. An imperative is categorical if it issues a valid command independent of personal desires or interests that would provide a reason for obeying the command. It is hypothetical if the validity of its command, if the reason why one can be expected to obey it, is the fact that one desires or is interested in something further that obedience to the command would entail. "Don't speed on the freeway if you don't want to be stopped by the police" is a hypothetical imperative. "It is wrong to break the law, so don't speed on the freeway" is a categorical imperative. The hypothetical command not to speed on the freeway is not valid for you if you do not care whether you are stopped by the police. The categorical command is valid for you either way. Autonomous moral agents can be expected to obey the command of a categorical imperative even if they lack a personal desire or interest in doing so. It remains an open question whether they will, however. The Kantian concept of autonomy is often misconstrued, leaving out the important point about the autonomous agent's self-subjection to the moral law. It is thought that autonomy is fully explained as the ability to obey a categorical command independently of a personal desire or interest in doing so—or worse, that autonomy is "obeying" a categorical command independently of a natural desire or interest; and that heteronomy, its opposite, is acting instead on personal motives of the kind referenced in hypothetical imperatives. In his Groundwork of the Metaphysic of Morals, Kant applied the concept of autonomy also to define the concept of personhood and human dignity. Autonomy, along with rationality, are seen by Kant as the two criteria for a meaningful life. Kant would consider a life lived without these not worth living; it would be a life of value equal to that of a plant or insect. According to Kant autonomy is part of the reason that we hold others morally accountable for their actions. Human actions are morally praise- or blame-worthy in virtue of our autonomy. Non- autonomous beings such as plants or animals are not blameworthy due to their actions being non-autonomous. Kant's position on crime and punishment is influenced by his views on autonomy. Brainwashing or drugging criminals into being law-abiding citizens would be immoral as it would not be respecting their autonomy. Rehabilitation must be sought in a way that respects their autonomy and dignity as human beings. According to Nietzsche Friedrich Nietzsche wrote about autonomy and the moral fight. Autonomy in this sense is referred to as the free self and entails several aspects of the self, including self-respect and even self-love. This can be interpreted as influenced by Kant (self-respect) and Aristotle (self-love). For Nietzsche, valuing ethical autonomy can dissolve the conflict between love (self-love) and law (self-respect) which can then translate into reality through experiences of being self-responsible. Because Nietzsche defines having a sense of freedom with being responsible for one's own life, freedom and self-responsibility can be very much linked to autonomy. According to Piaget The Swiss philosopher Jean Piaget (1896–1980) believed that autonomy comes from within and results from a "free decision". It is of intrinsic value and the morality of autonomy is not only accepted but obligatory. When an attempt at social interchange occurs, it is reciprocal, ideal and natural for there to be autonomy regardless of why the collaboration with others has taken place. For Piaget, the term autonomous can be used to explain the idea that rules are self-chosen. By choosing which rules to follow or not, we are in turn determining our own behaviour. Piaget studied the cognitive development of children by analyzing them during their games and through interviews, establishing (among other principles) that the children's moral maturation process occurred in two phases, the first of heteronomy and the second of autonomy: Heteronomous reasoning: Rules are objective and unchanging. They must be literal because the authority are ordering it and do not fit exceptions or discussions. The base of the rule is the superior authority (parents, adults, the State), that it should not give reason for the rules imposed or fulfilled them in any case. Duties provided are conceived as given from oneself. Any moral motivation and sentiments are possible through what one believes to be right. Autonomous reasoning: Rules are the product of an agreement and, therefore, are modifiable. They can be subject to interpretation and fit exceptions and objections. The base of the rule is its own acceptance, and its meaning has to be explained. Sanctions must be proportionate to the absence, assuming that sometimes offenses can go unpunished, so that collective punishment is unacceptable if it is not the guilty. The circumstances may not punish a guilty. Duties provided are conceived as given from the outside. One follows rules mechanically as it is simply a rule, or as a way to avoid a form of punishment. According to Kohlberg The American psychologist Lawrence Kohlberg (1927–1987) continues the studies of Piaget. His studies collected information from different latitudes to eliminate the cultural variability, and focused on the moral reasoning, and not so much in the behavior or its consequences. Through interviews with adolescent and teenage boys, who were to try and solve "moral dilemmas", Kohlberg went on to further develop the stages of moral development. The answers they provided could be one of two things. Either they choose to obey a given law, authority figure or rule of some sort or they chose to take actions that would serve a human need but in turn break this given rule or command. The most popular moral dilemma asked involved the wife of a man approaching death due to a special type of cancer. Because the drug was too expensive to obtain on his own, and because the pharmacist who discovered and sold the drug had no compassion for him and only wanted profits, he stole it. Kohlberg asks these adolescent and teenage boys (10-, 13- and 16-year-olds) if they think that is what the husband should have done or not. Therefore, depending on their decisions, they provided answers to Kohlberg about deeper rationales and thoughts and determined what they value as important. This value then determined the "structure" of their moral reasoning. Kohlberg established three stages of morality, each of which is subdivided into two levels. They are read in progressive sense, that is, higher levels indicate greater autonomy. Level 1: Premoral/Preconventional Morality: Standards are met (or not met) depending on the hedonistic or physical consequences. [Stage 0: Egocentric Judgment: There is no moral concept independent of individual wishes, including a lack of concept of rules or obligations.] Stage 1: Punishment-Obedience Orientation: The rule is obeyed only to avoid punishment. Physical consequences determine goodness or badness and power is deferred to unquestioningly with no respect for the human or moral value, or the meaning of these consequences. Concern is for the self. Stage 2: Instrumental-Relativist Orientation: Morals are individualistic and egocentric. There is an exchange of interests but always under the point of view of satisfying personal needs. Elements of fairness and reciprocity are present but these are interpreted in a pragmatic way, instead of an experience of gratitude or justice. Egocentric in nature but beginning to incorporate the ability to see things from the perspective of others. Level 2: Conventional Morality/Role Conformity: Rules are obeyed according to the established conventions of a society. Stage 3: Good Boy–Nice Girl Orientation: Morals are conceived in accordance with the stereotypical social role. Rules are obeyed to obtain the approval of the immediate group and the right actions are judged based on what would please others or give the impression that one is a good person. Actions are evaluated according to intentions. Stage 4: Law and Order Orientation: Morals are judged in accordance with the authority of the system, or the needs of the social order. Laws and order are prioritized. Level 3: Postconventional Morality/Self-Accepted Moral Principles: Standards of moral behavior are internalized. Morals are governed by rational judgment, derived from a conscious reflection on the recognition of the value of the individual inside a conventionally established society. Stage 5: Social Contract Orientation: There are individual rights and standards that have been lawfully established as basic universal values. Rules are agreed upon by through procedure and society comes to consensus through critical examination in order to benefit the greater good. Stage 6: Universal Principle Orientation: Abstract ethical principles are obeyed on a personal level in addition to societal rules and conventions. Universal principles of justice, reciprocity, equality and human dignity are internalized and if one fails to live up to these ideals, guilt or self-condemnation results. According to Audi Robert Audi characterizes autonomy as the self-governing power to bring reasons to bear in directing one's conduct and influencing one's propositional attitudes. Traditionally, autonomy is only concerned with practical matters. But, as Audi's definition suggests, autonomy may be applied to responding to reasons at large, not just to practical reasons. Autonomy is closely related to freedom but the two can come apart. An example would be a political prisoner who is forced to make a statement in favor of his opponents in order to ensure that his loved ones are not harmed. As Audi points out, the prisoner lacks freedom but still has autonomy since his statement, though not reflecting his political ideals, is still an expression of his commitment to his loved ones. Autonomy is often equated with self-legislation in the Kantian tradition. Self-legislation may be interpreted as laying down laws or principles that are to be followed. Audi agrees with this school in the sense that we should bring reasons to bear in a principled way. Responding to reasons by mere whim may still be considered free but not autonomous. A commitment to principles and projects, on the other hand, provides autonomous agents with an identity over time and gives them a sense of the kind of persons they want to be. But autonomy is neutral as to which principles or projects the agent endorses. So different autonomous agents may follow very different principles. But, as Audi points out, self-legislation is not sufficient for autonomy since laws that do not have any practical impact do not constitute autonomy. Some form of motivational force or executive power is necessary in order to get from mere self-legislation to self-government. This motivation may be inherent in the corresponding practical judgment itself, a position known as motivational internalism, or may come to the practical judgment externally in the form of some desire independent of the judgment, as motivational externalism holds. In the Humean tradition, intrinsic desires are the reasons the autonomous agent should respond to. This theory is called instrumentalism. Audi rejects instrumentalism and suggests that we should adopt a position known as axiological objectivism. The central idea of this outlook is that objective values, and not subjective desires, are the sources of normativity and therefore determine what autonomous agents should do. Child development Autonomy in childhood and adolescence is when one strives to gain a sense of oneself as a separate, self-governing individual. Between ages 1–3, during the second stage of Erikson's and Freud's stages of development, the psychosocial crisis that occurs is autonomy versus shame and doubt. The significant event that occurs during this stage is that children must learn to be autonomous, and failure to do so may lead to the child doubting their own abilities and feel ashamed. When a child becomes autonomous it allows them to explore and acquire new skills. Autonomy has two vital aspects wherein there is an emotional component where one relies more on themselves rather than their parents and a behavioural component where one makes decisions independently by using their judgement. The styles of child rearing affect the development of a child's autonomy. Autonomy in adolescence is closely related to their quest for identity. In adolescence parents and peers act as agents of influence. Peer influence in early adolescence may help the process of an adolescent to gradually become more autonomous by being less susceptible to parental or peer influence as they get older. In adolescence the most important developmental task is to develop a healthy sense of autonomy. Religion In Christianity, autonomy is manifested as a partial self-governance on various levels of church administration. During the history of Christianity, there were two basic types of autonomy. Some important parishes and monasteries have been given special autonomous rights and privileges, and the best known example of monastic autonomy is the famous Eastern Orthodox monastic community on Mount Athos in Greece. On the other hand, administrative autonomy of entire ecclesiastical provinces has throughout history included various degrees of internal self-governance. In ecclesiology of Eastern Orthodox Churches, there is a clear distinction between autonomy and autocephaly, since autocephalous churches have full self-governance and independence, while every autonomous church is subject to some autocephalous church, having a certain degree of internal self-governance. Since every autonomous church had its own historical path to ecclesiastical autonomy, there are significant differences between various autonomous churches in respect of their particular degrees of self-governance. For example, churches that are autonomous can have their highest-ranking bishops, such as an archbishop or metropolitan, appointed or confirmed by the patriarch of the mother church from which it was granted its autonomy, but generally they remain self-governing in many other respects. In the history of Western Christianity the question of ecclesiastical autonomy was also one of the most important questions, especially during the first centuries of Christianity, since various archbishops and metropolitans in Western Europe have often opposed centralizing tendencies of the Church of Rome. , the Catholic Church comprises 24 autonomous (sui iuris) Churches in communion with the Holy See. Various denominations of Protestant churches usually have more decentralized power, and churches may be autonomous, thus having their own rules or laws of government, at the national, local, or even individual level. Sartre brings the concept of the Cartesian god being totally free and autonomous. He states that existence precedes essence with god being the creator of the essences, eternal truths and divine will. This pure freedom of god relates to human freedom and autonomy; where a human is not subjected to pre-existing ideas and values. According to the first amendment, In the United States of America, the federal government is restricted in building a national church. This is due to the first amendment's recognizing people's freedom's to worship their faith according to their own belief's. For example, the American government has removed the church from their "sphere of authority" due to the churches' historical impact on politics and their authority on the public. This was the beginning of the disestablishment process. The Protestant churches in the United States had a significant impact on American culture in the nineteenth century, when they organized the establishment of schools, hospitals, orphanages, colleges, magazines, and so forth. This has brought up the famous, however, misinterpreted term of the separation of church and state. These churches lost the legislative and financial support from the state. The disestablishment process The first disestablishment began with the introduction of the bill of rights. In the twentieth century, due to the great depression of the 1930s and the completion of the second world war, the American churches were revived. Specifically the Protestant churches. This was the beginning of the second disestablishment when churches had become popular again but held no legislative power. One of the reasons why the churches gained attendance and popularity was due to the baby boom, when soldiers came back from the second world war and started their families. The large influx of newborns gave the churches a new wave of followers. However, these followers did not hold the same beliefs as their parents and brought about the political, and religious revolutions of the 1960s. During the 1960s, the collapse of religious and cultural middle brought upon the third disestablishment. Religion became more important to the individual and less so to the community. The changes brought from these revolutions significantly increased the personal autonomy of individuals due to the lack of structural restraints giving them added freedom of choice. This concept is known as "new voluntarism" where individuals have free choice on how to be religious and the free choice whether to be religious or not. Medicine In a medical context, respect for a patient's personal autonomy is considered one of many fundamental ethical principles in medicine. Autonomy can be defined as the ability of the person to make his or her own decisions. This faith in autonomy is the central premise of the concept of informed consent and shared decision making. This idea, while considered essential to today's practice of medicine, was developed in the last 50 years. According to Tom Beauchamp and James Childress (in Principles of Biomedical Ethics), the Nuremberg trials detailed accounts of horrifyingly exploitative medical "experiments" which violated the subjects' physical integrity and personal autonomy. These incidences prompted calls for safeguards in medical research, such as the Nuremberg Code which stressed the importance of voluntary participation in medical research. It is believed that the Nuremberg Code served as the premise for many current documents regarding research ethics. Respect for autonomy became incorporated in health care and patients could be allowed to make personal decisions about the health care services that they receive. Notably, autonomy has several aspects as well as challenges that affect health care operations. The manner in which a patient is handled may undermine or support the autonomy of a patient and for this reason, the way a patient is communicated to becomes very crucial. A good relationship between a patient and a health care practitioner needs to be well defined to ensure that autonomy of a patient is respected. Just like in any other life situation, a patient would not like to be under the control of another person. The move to emphasize respect for patient's autonomy rose from the vulnerabilities that were pointed out in regards to autonomy. However, autonomy does not only apply in a research context. Users of the health care system have the right to be treated with respect for their autonomy, instead of being dominated by the physician. This is referred to as paternalism. While paternalism is meant to be overall good for the patient, this can very easily interfere with autonomy. Through the therapeutic relationship, a thoughtful dialogue between the client and the physician may lead to better outcomes for the client, as he or she is more of a participant in decision-making. There are many different definitions of autonomy, many of which place the individual in a social context. Relational autonomy, which suggests that a person is defined through their relationships with others, is increasingly considered in medicine and particularly in critical and end-of-life care. Supported autonomy suggests instead that in specific circumstances it may be necessary to temporarily compromise the autonomy of the person in the short term in order to preserve their autonomy in the long-term. Other definitions of the autonomy imagine the person as a contained and self-sufficient being whose rights should not be compromised under any circumstance. There are also differing views with regard to whether modern health care systems should be shifting to greater patient autonomy or a more paternalistic approach. For example, there are such arguments that suggest the current patient autonomy practiced is plagued by flaws such as misconceptions of treatment and cultural differences, and that health care systems should be shifting to greater paternalism on the part of the physician given their expertise.  On the other hand, other approaches suggest that there simply needs to be an increase in relational understanding between patients and health practitioners to improve patient autonomy. One argument in favor of greater patient autonomy and its benefits is by Dave deBronkart, who believes that in the technological advancement age, patients are capable of doing a lot of their research on medical issues from their home. According to deBronkart, this helps to promote better discussions between patients and physicians during hospital visits, ultimately easing up the workload of physicians. deBronkart argues that this leads to greater patient empowerment and a more educative health care system. In opposition to this view, technological advancements can sometimes be viewed as an unfavorable way of promoting patient autonomy. For example, self-testing medical procedures which have become increasingly common are argued by Greaney et al. to increase patient autonomy, however, may not be promoting what is best for the patient. In this argument, contrary to deBronkart, the current perceptions of patient autonomy are excessively over-selling the benefits of individual autonomy, and is not the most suitable way to go about treating patients. Instead, a more inclusive form of autonomy should be implemented, relational autonomy, which factors into consideration those close to the patient as well as the physician. These different concepts of autonomy can be troublesome as the acting physician is faced with deciding which concept he/she will implement into their clinical practice. It is often references as one of the four pillars of medicine, alongside beneficence, justice and nonmaleficence Autonomy varies and some patients find it overwhelming especially the minors when faced with emergency situations. Issues arise in emergency room situations where there may not be time to consider the principle of patient autonomy. Various ethical challenges are faced in these situations when time is critical, and patient consciousness may be limited. However, in such settings where informed consent may be compromised, the working physician evaluates each individual case to make the most professional and ethically sound decision. For example, it is believed that neurosurgeons in such situations, should generally do everything they can to respect patient autonomy. In the situation in which a patient is unable to make an autonomous decision, the neurosurgeon should discuss with the surrogate decision maker in order to aid in the decision-making process. Performing surgery on a patient without informed consent is in general thought to only be ethically justified when the neurosurgeon and his/her team render the patient to not have the capacity to make autonomous decisions. If the patient is capable of making an autonomous decision, these situations are generally less ethically strenuous as the decision is typically respected. Not every patient is capable of making an autonomous decision. For example, a commonly proposed question is at what age children should be partaking in treatment decisions. This question arises as children develop differently, therefore making it difficult to establish a standard age at which children should become more autonomous. Those who are unable to make the decisions prompt a challenge to medical practitioners since it becomes difficult to determine the ability of a patient to make a decision. To some extent, it has been said that emphasis of autonomy in health care has undermined the practice of health care practitioners to improve the health of their patient as necessary. The scenario has led to tension in the relationship between a patient and a health care practitioner. This is because as much as a physician wants to prevent a patient from suffering, they still have to respect autonomy. Beneficence is a principle allowing physicians to act responsibly in their practice and in the best interests of their patients, which may involve overlooking autonomy. However, the gap between a patient and a physician has led to problems because in other cases, the patients have complained of not being adequately informed. The seven elements of informed consent (as defined by Beauchamp and Childress) include threshold elements (competence and voluntariness), information elements (disclosure, recommendation, and understanding) and consent elements (decision and authorization). Some philosophers such as Harry Frankfurt consider Beauchamp and Childress criteria insufficient. They claim that an action can only be considered autonomous if it involves the exercise of the capacity to form higher-order values about desires when acting intentionally. What this means is that patients may understand their situation and choices but would not be autonomous unless the patient is able to form value judgements about their reasons for choosing treatment options they would not be acting autonomously. In certain unique circumstances, government may have the right to temporarily override the right to bodily integrity in order to preserve the life and well-being of the person. Such action can be described using the principle of "supported autonomy", a concept that was developed to describe unique situations in mental health (examples include the forced feeding of a person dying from the eating disorder anorexia nervosa, or the temporary treatment of a person living with a psychotic disorder with antipsychotic medication). While controversial, the principle of supported autonomy aligns with the role of government to protect the life and liberty of its citizens. Terrence F. Ackerman has highlighted problems with these situations, he claims that by undertaking this course of action physician or governments run the risk of misinterpreting a conflict of values as a constraining effect of illness on a patient's autonomy. Since the 1960s, there have been attempts to increase patient autonomy including the requirement that physician's take bioethics courses during their time in medical school. Despite large-scale commitment to promoting patient autonomy, public mistrust of medicine in developed countries has remained. Onora O'Neill has ascribed this lack of trust to medical institutions and professionals introducing measures that benefit themselves, not the patient. O'Neill claims that this focus on autonomy promotion has been at the expense of issues like distribution of healthcare resources and public health. One proposal to increase patient autonomy is through the use of support staff. The use of support staff including medical assistants, physician assistants, nurse practitioners, nurses, and other staff that can promote patient interests and better patient care. Nurses especially can learn about patient beliefs and values in order to increase informed consent and possibly persuade the patient through logic and reason to entertain a certain treatment plan. This would promote both autonomy and beneficence, while keeping the physician's integrity intact. Furthermore, Humphreys asserts that nurses should have professional autonomy within their scope of practice (35–37). Humphreys argues that if nurses exercise their professional autonomy more, then there will be an increase in patient autonomy (35–37). International human rights law After the Second World War, there was a push for international human rights that came in many waves. Autonomy as a basic human right started the building block in the beginning of these layers alongside liberty. The Universal declarations of Human rights of 1948 has made mention of autonomy or the legal protected right to individual self-determination in article 22. Documents such as the United Nations Declaration on the Rights of Indigenous Peoples reconfirm international law in the aspect of human rights because those laws were already there, but it is also responsible for making sure that the laws highlighted when it comes to autonomy, cultural and integrity; and land rights are made within an indigenous context by taking special attention to their historical and contemporary events The United Nations Declaration on the Rights of Indigenous Peoples article 3 also through international law provides Human rights for Indigenous individuals by giving them a right to self-determination, meaning they have all the liberties to choose their political status, and are capable to go and improve their economic, social, and cultural statuses in society, by developing it. Another example of this, is article 4 of the same document which gives them autonomous rights when it comes to their internal or local affairs and how they can fund themselves in order to be able to self govern themselves. Minorities in countries are also protected as well by international law; the 27th article of the United Nations International covenant on Civil and Political rights or the ICCPR does so by allowing these individuals to be able to enjoy their own culture or use their language. Minorities in that manner are people from ethnic religious or linguistic groups according to the document. The European Court of Human rights, is an international court that has been created on behalf of the European Conventions of Human rights. However, when it comes to autonomy they did not explicitly state it when it comes to the rights that individuals have. The current article 8 has remedied to that when the case of Pretty v the United Kingdom, a case in 2002 involving assisted suicide, where autonomy was used as a legal right in law. It was where Autonomy was distinguished and its reach into law was marked as well making it the foundations for legal precedent in making case law originating from the European Court of Human rights. The Yogyakarta Principles, a document with no binding effect in international human rights law, contend that "self-determination" used as meaning of autonomy on one's own matters including informed consent or sexual and reproductive rights, is integral for one's self-defined or gender identity and refused any medical procedures as a requirement for legal recognition of the gender identity of transgender. If eventually accepted by the international community in a treaty, this would make these ideas human rights in the law. The Convention on the Rights of Persons with Disabilities also defines autonomy as principles of rights of a person with disability including "the freedom to make one's own choices, and independence of persons". Celebrity culture on teenage autonomy A study conducted by David C. Giles and John Maltby conveyed that after age-affecting factors were removed, a high emotional autonomy was a significant predictor of celebrity interest, as well as high attachment to peers with a low attachment to parents. Patterns of intense personal interest in celebrities was found to be conjunction with low levels of closeness and security. Furthermore, the results suggested that adults with a secondary group of pseudo-friends during development from parental attachment, usually focus solely on one particular celebrity, which could be due to difficulties in making this transition. Various uses In computing, an autonomous peripheral is one that can be used with the computer turned off. Within self-determination theory in psychology, autonomy refers to 'autonomy support versus control', "hypothesizing that autonomy-supportive social contexts tend to facilitate self-determined motivation, healthy development, and optimal functioning." In mathematical analysis, an ordinary differential equation is said to be autonomous if it is time-independent. In linguistics, an autonomous language is one which is independent of other languages, for example, has a standard variety, grammar books, dictionaries or literature, etc. In robotics, "autonomy means independence of control. This characterization implies that autonomy is a property of the relation between two agents, in the case of robotics, of the relations between the designer and the autonomous robot. Self-sufficiency, situatedness, learning or development, and evolution increase an agent's degree of autonomy.", according to Rolf Pfeifer. In spaceflight, autonomy can also refer to crewed missions that are operating without control by ground controllers. In economics, autonomous consumption is consumption expenditure when income levels are zero, making spending autonomous to income. In politics, autonomous territories are States wishing to retain territorial integrity in opposition to ethnic or indigenous demands for self-determination or independence (sovereignty). In anti-establishment activism, an autonomous space is another name for a non-governmental social center or free space (for community interaction). In social psychology, autonomy is a personality trait characterized by a focus on personal achievement, independence, and a preference for solitude, often labeled as an opposite of sociotropy. Limits to autonomy Autonomy can be limited. For instance, by disabilities, civil society organizations may achieve a degree of autonomy albeit nested within—and relative to—formal bureaucratic and administrative regimes. Community partners can therefore assume a hybridity of capture and autonomy—or a mutuality—that is rather nuanced. Semi-autonomy The term semi-autonomy (coined with prefix semi- / "half") designates partial or limited autonomy. As a relative term, it is usually applied to various semi-autonomous entities or processes that are substantially or functionally limited, in comparison to other fully autonomous entities or processes. Quasi-autonomy The term quasi-autonomy (coined with prefix quasi- / "resembling" or "appearing") designates formally acquired or proclaimed, but functionally limited or constrained autonomy. As a descriptive term, it is usually applied to various quasi-autonomous entities or processes that are formally designated or labeled as autonomous, but in reality remain functionally dependent or influenced by some other entity or process. An example for such use of the term can be seen in common designation for quasi-autonomous non-governmental organizations.

Traditional ecological knowledge

Traditional ecological knowledge (TEK) describes indigenous and other traditional knowledge of local resources. As a field of study in North American anthropology, TEK refers to "a cumulative body of knowledge, belief, and practice, evolving by accumulation of TEK and handed down through generations through traditional songs, stories and beliefs. It is concerned with the relationship of living beings (including human) with their traditional groups and with their environment." Indigenous knowledge is not a universal concept among various societies, but is referred to a system of knowledge traditions or practices that are heavily dependent on "place". TEK encompasses a diverse range of knowledge across ecologies and communities around the world. It is rooted in generations of practice and care in tending to the land and the environment. TEK has the power to both complement and correct present-day climate solutions, providing a critical ancestral perspective that can help restore balance. However, simultaneously, the implementation of TEK must be enacted with consideration and immediate involvement of indigenous communities, as otherwise, the burden to find a solution will fall upon them. TEK, like many other forms of indigenous knowledge and sciences, can often be sacred, so it is critical to engage closely with the community to not disrespect their ancestral wisdom. Inherently, TEK exists in the liminal space between science and spirituality, intricately merging these two realms which seem at odds in the current Western world. The application of TEK in the field of ecological management and science is still controversial, as methods of acquiring and collecting knowledge—although often including forms of empirical research and experimentation—differ from those used to create and validate scientific ecological knowledge from a Western perspective. Non-tribal government agencies, such as the U.S. EPA, have established integration programs with some tribal governments in order to incorporate TEK in environmental plans and climate change tracking. There is a debate whether Indigenous populations retain an intellectual property right over traditional knowledge and whether use of this knowledge requires prior permission and license. This is especially complicated because TEK is most frequently preserved as oral tradition and as such may lack objectively confirmed documentation. As such, the same methods that could resolve the issue of documentation to meet Western requirements may compromise the very nature of traditional knowledge. Traditional knowledge is used to maintain resources necessary for survival. While TEK itself, and the communities tied to the oral tradition, may become threatened in the context of rapid climate change or environmental degradation, TEK is proving critical for understanding the impacts of those changes within the ecosystem. TEK can also refer to traditional environmental knowledge which emphasizes the different components and interactions of the environment. History The earliest systematic studies of TEK were conducted in anthropology. Ecological knowledge was studied through the lens of ethnoecology, "an approach that focuses on the conceptions of ecological relationships held by a people or a culture," in understanding how systems of knowledge were developed by a given culture. Harold Colyer Conklin, an American anthropologist who pioneered the study of ethnoscience, took the lead in documenting indigenous ways of understanding the natural world. Conklin and others documented how traditional peoples, such as Philippine horticulturists, displayed remarkable and exceptionally detailed knowledge about the natural history of places where they resided. Direct involvement in gathering, fashioning products from, and using local plants and animals created a scheme in which the biological world and the cultural world were tightly intertwined. In emphasizing the study of adaptive processes, which argues that social organization itself is an ecological adaptational response by a group to its local environment, human-nature relations and the practical techniques on which these relationships and culture depended, the field of TEK could analyze a broad range of questions related to cultural ecology and ecological anthropology. By the mid-1980s a growing body of literature on traditional ecological knowledge documented both the environmental knowledge held by diverse indigenous peoples and their ecological relations. The rise of traditional ecological knowledge at this time led to international recognition of its potential applications in resource management practices and sustainable development. The 1987 report by the World Commission on Environment and Development reflects the consensus at the time. The report points out that the successes of the 20th century (decreases in infant mortality, increases in life expectancy, increases in literacy, and global food production) have given rise to trends that have caused environmental decay "in an ever more polluted world among ever decreasing resources." Hope, however, existed for traditional lifestyles. The report declared that tribal and indigenous peoples had lifestyles that could provide modern societies with lessons in the management of resources in complex forest, mountain, and dryland ecosystems. Fulvio Mazzocchi of the Italian National Research Council's Institute of Atmospheric Pollution contrasts traditional knowledge from scientific knowledge as follows: Some anthropologists, such as M. Petriello and A. Stronza, have demonstrated that non-Indigenous groups such as campesinos possess TEK. They warn that presenting TEK as an indigenous construct will cause the privileging of certain types of TEK over others and the restricting of which groups are thought to possess TEK, resulting in reduced understanding of and collaboration with these groups. Aspects of traditional ecological knowledge The aspects of traditional ecological knowledge provide different typologies in how it is utilized and understood. These are good indicators in how it is used from different perspectives and how they are interconnected, providing more emphasis on "cooperative management to better identify areas of difference and convergence when attempting to bring two ways of thinking and knowing together." Factual observations Houde identifies six faces of traditional ecological knowledge. The first aspect of traditional ecological knowledge incorporates the factual, specific observations generated by recognition, naming, and classification of discrete components of the environment. This aspect is about understanding the interrelationship with species and their surrounding environment. It is also a set of both empirical observations and information emphasizing the aspects of animals and their behavior, and habitat, and the physical characteristics of species, and animal abundance. This is most useful for risk assessment and management which provides nations with opportunity to influence resource management. However, if a nation does not act, then the state may act on its own interests. This type of "empirical knowledge consists of a set of generalized observations conducted over a long period of time and reinforced by accounts of other TEK holders." Management systems The second face refers to the ethical and sustainable use of resources in regards to management systems. This is achieved through strategic planning to ensure resource conservation. More specifically this face involves dealing with pest management, resource conversion, multiple cropping patterns, and methods for estimating the state of resources. It also focuses on resource management and how it adapts to local environments. Past and current uses The third face refers to the time dimension of TEK, focusing on past and current uses of the environment transmitted through oral history, such as land use, settlement, occupancy, and harvest levels. Specifically medicinal plants and historical sites are great concerns. Oral history is used to transmit cultural heritage generation to generation, and contributes to a sense of family and community. Ethics and values The fourth face refers to value statements and connections between the belief system and the organization of facts. In regards to TEK it refers to environmental ethics that keeps exploitative abilities in check. This face also refers to the expression of values concerning the relationship with the habitats of species and their surrounding environment - the human-relationship environment. Culture and identity The fifth face refers to the role of language and images of the past giving life to culture. The relationship between Aboriginals (original inhabitants) and their environment is vital to sustaining the cultural components that define them. This face reflects the stories, values, and social relations that reside in places as contributing to the survival, reproduction, and evolution of aboriginal cultures, and identities. It also stresses "the restorative benefits of cultural landscapes as places for renewal" Cosmology The sixth face is a culturally based cosmology that is the foundation of the other aspects. Cosmology is the notion of how the world works for many cultures. This can vary greatly from one culture to the next. In the U.S for example, there are over 577 federally recognized tribes with their own culture, languages and belief system. Many of these tribes understand themselves as interconnected with the land. The term 'cosmology' relates to the assumptions and beliefs about how things work, and explains the way in which things are connected, and gives principles that regulate human–animal relations and the role of humans in the world. From an anthropological perspective, cosmology attempts to understand the human-animal relationship and how these directly influence social relationships, obligations toward community members, and management practices. In A Yupiaq Worldview: A Pathway to Ecology and Spirit by Angayuqaq Oscar Kawagley, an Indigenous anthropologist, says "The balance of nature, or ecological perspective, was of utmost importance to the Yupiaq. History and archeological findings of different race in the world seem to indicate a common philosophical or ecological thread among all people, and this apparent linking leads to the concept of interconnectedness of all things of the universe. The Yupiaq people were, and still are, proponents of this worldview, in spite of the weakening of the ecological perspective by modern intrusions." Kawagley elaborates more on TEK in the Yupiaq worldview by saying that, "The Yupiaq person's methodologies include observation, experience, social interaction, and listening to the conversations and interrogations of the natural and spiritual worlds with the mind. The person is always a participant-observer." Ecosystem management Ecosystem management is a multifaceted and holistic approach to natural resource management. It incorporates both science and traditional ecological knowledge to collect data from long term measures that science cannot. This is achieved by scientists and researchers collaborating with Indigenous peoples through a consensus decision-making process while meeting the socioeconomic, political and cultural needs of current and future generations. Indigenous knowledge has developed a way to deal with the complexity while western science has the techniques and tools. This is a good relationship to have which creates a better outcome for both sides and the environment. The dangers of working together is that nations do not benefit fairly or at all. Many times Indigenous knowledge has been used outside of the nation without consent (cultural appropriation), acknowledgment, or compensation. Indigenous knowledge can sustain the environment, yet it can be sacred knowledge. Ecological restoration Ecological restoration is the practice of restoring a degraded ecosystem through human intervention. There are many links between ecological restoration and ecosystem management practices involving TEK, however TEK ecosystem management is much more in-depth through the historical relationship with the place. Due to the aforementioned unequal power between indigenous and non-indigenous peoples, it is vital that partnerships are equitable to restore social injustices and this has proven to be successful when Indigenous Peoples lead ecological restoration projects. Effects of environmental degradation In some areas, environmental degradation has led to a decline in traditional ecological knowledge. For example, at the Aamjiwnaang community of Anishnaabe First Nations people in Sarnia, Ontario, Canada, residents suffer from a "noticeable decrease in male birth ratio ..., which residents attribute to their proximity to petrochemical plants". Climate change Traditional ecological knowledge provides information about climate change across generations and geography of the actual residents in the area. Traditional ecological knowledge emphasizes and makes the information about the health and interactions of the environment the center of the information it carries. Climate change affects traditional ecological knowledge in the forms of the indigenous people's identity and the way they live their lives. Traditional knowledge is passed down from generation to generation and continues today. Indigenous people depend on these traditions for their livelihood. For many harvesting seasons, indigenous people have shifted their activity months earlier due to impacts from climate change. The rising temperature poses as threats for ecosystems because it harms the livelihoods of certain tree and plant species. The combination of the rise in temperatures and change in precipitation levels affects plant growth locations. The warming also affects insects and animals. The change in temperatures can affect many aspects from the times that insects emerge throughout the year to the changes in the habitats of animals throughout seasonal changes. As the temperature gets hotter, wild fires become more likely. One Indigenous nation in Australia was recently given back land and are reinstating their traditional practice of controlled burning. This has resulted in increased biodiversity and decreased severity of wildfires. Not only are different aspects of the environment affected, but together, the health of the ecosystem is affected by climate change and so the environmental resources available to the indigenous people can change in the amount available and the quality of the resources. As sea ice levels decrease, Alaska Native peoples experience changes in their daily lives; fishing, transportation, social and economic aspects of their lives become more unsafe. The defrosting of soil has caused damages to buildings and roadways. Water contamination becomes exacerbated as clean water resources dwindle. Climate changes undermine the daily lives of the Native peoples on many levels. Climate change and indigenous people have a varying relationship depending on the geographic region which require different adaption and mitigation actions. For example, to immediately deal with these conditions, the indigenous people adjust when they harvest and what they harvest and also adjust their resource use. Climate change can change the accuracy of the information of traditional ecological knowledge. The indigenous people have relied deeply on indicators in nature to plan activities and even for short- term weather predictions. As a result of even more increasing unfavorable conditions, the indigenous people relocate to find other ways to survive. As a result, there is a loss of cultural ties to the lands they once resided on and there is also a loss to the traditional ecological knowledge they had with the land there. Climate change adaptations not properly structured or implemented can harm the indigenous people's rights. The EPA has mentioned that it would take traditional ecological knowledge into consideration in planning adaptations to climate change. The National Resource Conservation Service of the United States Department of Agriculture has used methods of the indigenous people to combat climate change conditions. Case study: Savoonga and Shaktoolik, Alaska In one study, villagers of Savoonga and Shaktoolik, Alaska reported that over the last twenty years of their lives, the weather has become more difficult to predict, the colder season has shortened, there is more difficulty in predicting the amount of plants available for harvests, there are differences in animal migrations, there are more sightings of new species than before, and the activities of hunting and gathering have become not as predictable nor occur as often due to more limited availability to do so. The residents saw a noticeable change in their climate which also affected their livelihoods. The plants and animals are not as consistent with their availability which affects the residents' hunting and gathering because there is not as much to hunt or gather. The appearance of new species of plants and animals is also a physical and nutritional safety concern because they are not traditionally part of the land. Examples Karuk and Yurok Burning According to environmental sociologist Kirsten Vinyeta and tribal climate change researcher Kathy Lynn, "the Karuk Tribe of California occupies aboriginal land along the middle course of the Klamath and Salmon Rivers in Northern California. The Tribe's aboriginal territory includes an estimated 1.38 million acres within the Klamath River Basin. Traditional burning practices have been critical to the Karuk since time immemorial. For the Tribe, fire serves as a critical land management tool as well as a spiritual practice." According to environmental studies professor Tony Marks-Block, ecological researcher Frank K. Lake and tropical forester Lisa M. Curran, "before widespread fire exclusion policies, American Indians used to broadcast understory fires or cultural burns to enhance resources integral for their livelihood and cultural practices. To restore ecocultural resources depleted from decades of fire exclusion and to reduce wildfire risks, the Karuk and the Yurok Tribes of Northwest California are leading regional collaborative efforts to expand broadcast fires and fuel reduction treatments on public, private, and Tribal lands in their ancestral territories." Tony Marks-Block, Frank K. Lake and Lisa M. Curran also state that "in Karuk territory, the federal government did not establish a reservation, leaving merely 3.83 square kilometers of Karuk trust lands in their ancestral territory, with the remainder largely under the jurisdiction of the Klamath and Six Rivers National Forests and scattered private homesteads. As a result, Karuk Tribal members and management agencies must navigate the USDA Forest Service claims on their ancestral territory and have limited options to expand their land base through the acquisition of private land holdings. In Yurok territory, multiple overlapping jurisdictions occur including Redwood National Park and Six Rivers National Forest outside of the reservation established by the federal government. The reservation is under private timber company ownership. Consequently, the Yurok Tribe must either coordinate or interact with multiple actors within their ancestral territory, but they presently have greater options for acquiring private properties than the Karuk Tribe." According to professor of sociology Kari Norgaard and Karuk tribe member William Tripp, "this process can then be replicated and expanded to other communities throughout the western Klamath Mountains and beyond. Hoopa and Yurok tanoak stands that experienced repeated fire were more resilient to the disease over time. Some research indicates dramatic differences in disease incidence immediately following wildfire (72 times less likely to be found in burned versus unburned plots in the same area), although it has been shown to steadily recover in the absence of repeated fire, because the disease can survive in hosts not killed by the fire." Anishinabe Ecological Conservation According to authors Bobbie Kalman and Niki Walker, "indigenous, or Native, people have lived in the Great Lakes region for thousands of years. People of the Anishinabe (Anishinaabe) nation lived in territories in the western Great Lakes region. According to oral tradition, the Anishinabe people once lived by a huge body of salt water, which may have been the Atlantic Ocean or Hudson's Bay. The people received a prophecy, or prediction, that if they traveled inland, they would find a place where food grew on water. Some went west, following a vision of a megis, or cowrie shell, that guided them to the western Great Lakes. The people split into groups and settled in different spots that together made up the Anishinabe nation. The Anishinabe had an especially close relationship with two other nations in the western Great Lakes region being the Odawa (Ottawa) and Potawatomi. People of these three nations often married one another, traded goods, and worked together to settle disputes. They also gathered at councils, where they made decisions together." According to indigenous philosopher and climate/environmental justice scholar Kyle Powys Whyte, Anishinabe people throughout the Great Lakes region are at the forefront of native species conservation and ecological restoration. Nmé is the largest and oldest living fish in the Great Lakes basin, sometimes exceeding 100 years in age. Nmé served the Asnishinabe people as a substantial source of food, an indicator species for monitoring the environment, and a lachlan identity, playing a role in ceremonies and stories. Kenny Pheasant, an elder says, "Decline of the sturgeon has corresponded with decline in sturgeon clan families. Only a few sturgeon clan families are known around here" (Little River Band). The Natural Resources Department of the Ottawa Indians started a cultural context group, composed of a diverse range of tribal members and biologists, which developed goals and objectives for restoration. The goal was to "restore the harmony and connectivity between Nmé and the Anishinabe people and bring them both back to the river. Ultimately, the department created the first streamside rearing facility for protecting young sturgeon before they are released each fall in order to preserve their genetic parentage. Wild rice, or manoomin, grows in shallow, clear, and slow-moving waterways and can be harvested in early autumn. After harvesting, manoomin is processed through activities such as drying, parching, hulling, winnowing, and cleaning. After the Anishinabe migrated from the East and reached the Great Lakes region where they could grow crops on the water, neighboring groups of US and Canadian citizens and companies engaged in activities such as mining, damming, commercial farming and recreational boating. These activities directly affect manoomin and its habitat. Today the Anishinabe people are leaders in the conservation of wild rice. The Nibi (water) and Manoomin Symposium, which takes place every two years, brings tribal rice harvesters in the Great Lakes, indigenous scholars, paddy rice growers, representatives from mining companies and state agencies, and university researchers interested in the genetic modification of rice together. Elders share their stories about manoomin and youth share their perspective on how manoomin fits into their futures. Indigenous persons working as scientists in their tribes share the experiences working with elders to understand the deep historical implications of the work they do to study and conserve manoomin. Other indigenous people are often invited to share their experiences restoring and conserving other native species, such as taro and maize. Lummi Nation of Washington State Conservation of Southern Resident Killer Whales According to ecological scholars Paul Guernsey, Kyle Keeler and Lummi member Jeremiah Julius, "the Lummi Nation of Washington State is a native American tribe of the Salish Sea. In 2018, the Lummi Nation dedicated itself to a Totem Pole Journey across the United States calling for the return of their relative "Lolita" (a Southern Resident Killer Whale) to her home waters. In the Salish language, killer whales are referred to as qwe 'lhol mechen, meaning 'our relations under the waves', but the Lummi are not simply 'related to' the whales in a generic fashion, the whales are a relation in the sense that they are kin. When NOAA first designated the Southern Resident killer whale an endangered distinct population segment (DPS) in 2005, they juridically eliminated "Lolita" as a family member. The decision reads, "The Southern Resident killer whale DPS does not include killer whales from J, K or L pod placed in captivity prior to listing, nor does it include their captive born progeny" (NOAA, 2005). The Lummi are asking for NOAA to collaborate in feeding the whales until the chinook runs of the Puget Sound can sustain them. The Lummi have embarked on ceremonial feedings of their relatives, but they are told by NOAA that larger-scale efforts would require federal permission and partnership. Although one of the organization's conservation goals is to ensure 'sufficient quantity, quality and accessibility of prey species', NOAA understands this policy strictly as a habitat issue. They have been clear that now is not the time for complacency due to 'insufficient data' or uncertainty. The Lummi continue their annual Totem Pole Journey to protect their older siblings, the blackfish, and to keep coal, oil and other threats out of the Salish Sea. These healing practices are fashioned to address what Maria Yellow Horse Brave Heart and Lemyra M. DeBruyn have called "historical unresolved grief". Hunting Culture of Campesinos of the Rivas Department, Nicaragua M. Petriello and A. Stronza gathered information about the TEK around hunting for a campesino community in the Rivas Department, Nicaragua, by combining a cultural consensus analysis (CCA) with ethnoecological ethnographic information. The framework they used to analyze TEK was the k-c-p complex.  This categorizes information into kosmos (shared worldview, beliefs, and ethics), corpus (descriptive and classificatory knowledge), and praxis (resource use strategies). For the campesinos of the area, hunting is for subsistence instead of commercial use and is used to diversify their diet.  There is also an emphasis on avoiding overhunting.  Dogs are an integral part of hunting, and their use requires a connection between the hunter and dog and knowledge of their dogs' prey preferences. Knowledge required for hunting includes animal behavior, which methods to use for which animal, and how to clean and prepare the hunted animal. They distinguish hunted species from rarely- and non-hunted species through the classification of modes of knowledge about them: conocer (direct, personally known) or saber (indirect, factually known). One can be able to know (conocer) an animal through experience with it including hunting. Hunting secrets are the beliefs surrounding how certain parts of some animals can cause different effects if treated in certain ways. Not all animals of the same species contain the secret(s) of their species. It was believed that "nails" (likely caudal osteoderms) from the tip of armadillos' tails, stones (bezoars) and fangs from white-tailed deers, and bile ducts from pacas would bring luck when hunting.  If someone else sees the secrets/amulets of the armadillo and white-tailed deer then they would lose their luck and one may never be able to hunt anything again. Paca bile ducts were not believed to lose their luck when seen by others. Agroforestry in northeast India Indigenous wisdom in India in relation to agroforestry has been passed down for generations. A revival of traditional farming methods is needed to rectify the impacts of centuries of colonial-era land devastation and the more recent neoliberal land corporatization. One example of this would be jhum, also known as shifting cultivation or "slash and burn". This is a common practice in northeastern India, where sections of land are regularly burned and returned to after the soil's fertility is restored. The practice of jhum is known to heighten carbon storage and biodiversity. Jhum is paired with plant-based pesticides to create an agroforestry structure that is not dependent on Western fertilizers and pesticides. However, it is important to note that practicing jhum incorrectly or after an inconsistent gap has been associated with soil erosion and depletion of top soil. TEK and government bodies United Nations fora The 1992 Rio Declaration signed at the United Nations Conference on Environment and Development expresses a positive view of traditional ecological knowledge. U.S. Environmental Protection Agency The U.S. Environmental Protection Agency was one of the first federal agencies to develop formal policies detailing how it would collaborate with tribal governments and acknowledge tribal interests in enacting its programs "to protect human health and the environment." In recognizing tribal peoples connection to the environment the EPA has sought to develop environmental programs that integrate traditional ecological knowledge into the "agency's environmental science, policy, and decision-making processes." Although TEK is not currently recognized as an important component of mainstream environmental decision making, scientists are working on developing core science competency programs that align with TEK and promote self-sufficiency and determination. The lack of recognition for traditional ecological knowledge in determining solutions to environmental issues is representational of the ethnocentric tendency to value science over traditional models. Therefore, agencies integrating science and TEK must acknowledge the values of unique pedagogical methods in order to fully utilize the benefits of both science and TEK. For example, US agencies must learn about TEK through the lens of indigenous groups by working side by side with Indigenous Elders, gather hands-on data from the specific place in question, and incorporating indigenous values into their scientific evaluation. In November 2000, U.S. President Bill Clinton issued Executive Order 13175, which required federal departments and agencies to consult with Indian Tribal governments in the development of policies that would have Tribal implications. Tribal Implications are defined by the EPA as having "substantial direct effects on one or more Indian tribes, on the relationship between the federal government and Indian tribes, or on the distribution of power and responsibilities between the federal government and Indian tribes." As a Federal agency of the U.S. government, the EPA was required to establish a set of standards for the consultation process. As its initial response, the agency developed a set of standards that would allow for meaningful communication and coordination between the agency and tribal officials prior to the agency taking actions or implementing decisions that may affect tribes. The standards also designated EPA consultation contacts to promote consistency and coordination of the consultation process, and established management oversight and reporting to ensure accountability and transparency. One form of consultation has been EPA Tribal Councils. In 2000, the EPA's Office of Research and Development formed the EPA Tribal Science Council. The council, made up of representatives from tribes across the nation, is meant to provide a structure for tribal involvement in EPA's science efforts, and serve as a vehicle through which EPA may gain an understanding of the scientific issues that are of highest priority to tribes at a national level. The council also offers tribes an opportunity to influence EPA's scientific agenda by raising these priority issues to an EPA-wide group. Of importance for tribal members at the initial gathering of the EPA Tribal Science Council was the inherent differences in tribal traditional lifeways (TTL) and western science. These lifeways include "spiritual, emotional, physical, and mental connections to the environment; connections which are based on intrinsic, immeasurable values"; and an understanding that the earth's resources will provide everything necessary for human survival. The EPA's Tribal Science Council, however, was meant to act as a meeting place where both groups could "share information that may contribute to environmental protection for all peoples with neither culture relinquishing its identity." In an effort to protect TTL the Council identified subsistence as a critical area for investigation. The EPA-Tribal Science Council defined subsistence as: the "relationships between people and their surrounding environment, a way of living. Subsistence involves an intrinsic spiritual connection to the earth, and includes an understanding that the earth's resources will provide everything necessary for human survival. People who subsist from the earth's basic resources remain connected to those resources, living within the circle of life. Subsistence is about living in a way that will ensure the integrity of the earth's resources for the beneficial use of generations to come." Because TTL or TEK is specific to a location and includes the relationships between plants and animals, and the relationship of living beings to the environment, acknowledgment of subsitence as a priority allows for the knowledge and practices of TTL to be protected. For example, as part of their deliberation regarding subsistence, the Council agreed to identify resource contamination as "the most critical tribal science issue at this time." Because tribal people with subsistence lifestyles rely the environment for traditional techniques of farming, hunting. fishing, forestry, and medicines, and ceremonies, contaminants disproportionately impact tribal peoples and jeopardizes their TTL. As the EPA Council stated, "Tribal subsistence consumption rates are typically many times higher than those of the general population, making the direct impact of resource contamination a much more immediate concern." As native peoples struggle with tainted resources, the council has made progress in investigating its impacts. Despite such efforts, there are still barriers to progress within the EPA-Tribal Science Council. For example, one obstacle has been the nature of TTL. Tribal Traditional Lifeways are passed down orally, from person to person, generation to generation, whereas western science relies on the written word, communicated through academic and literate transmission. Endeavors to bring together western scientists and tribal people have also been hindered by Native American's perceptions that scientific analysis are put in a metaphorical "black box" that shuts out tribal input. Regardless, the EPA has recognized the ability of indigenous knowledge to advance scientific understanding and provide new information and perspectives that may benefit the environment and human health. The integration of TTL into the EPA's risk assessment paradigm is one example of how the EPA-Tribal Science Council has been able to enact change in EPA culture. The risk assessment paradigm is an "organizing framework for the scientific analysis of the potential for harmful impacts to human health and the environment as a result of exposure to contaminants or other environmental stressors." Risk assessment has been used by the EPA to establish "clean-up levels at hazardous waste sites, water quality and air quality criteria, fish advisories, and bans or restricted uses for pesticides and other toxic chemicals." Tribal people are concerned, however, that current risk assessment methodologies do not afford complete value to tribal culture, values, and/or life ways. The Tribal Science Council seeks to incorporate TTL into exposure assumptions existent in the EPA risk assessment model. A long-term goal for the EPA's Tribal Science Council, however, is a complete shift in decision-making assessments from risk to preserving a healthy people and environment. As stated above, tribal people do not accept a separation of the human and ecological condition when they characterize risk. Through EPA initiated seminar, workshops, and projects, tribes have been able to engage in dialogue about the integration of Tribal Traditional Lifeways into EPA risk assessment and decision-making. This has occurred in a number of ways: inclusion of unique tribal cultural activities such as native basketry, the importance of salmon and other fishes, native plant medicine, consumption of large amounts of fish and game, and sweat lodges as exposures for estimating potential risk to people or to communities. Although these types of tribal specific activities may be included in EPA's risk assessment, there is no assurance that they will be included nor is there consistency in how they may be applied at different sites across the country. In July 2014, the EPA announced its "Policy on Environmental Justice for Working with Federally Recognized Tribes and Indigenous Peoples," setting forth its principles for programs related to federally recognized tribes and indigenous peoples in order to "support the fair and effective implementation of federal environmental laws, and provide protection from disproportionate impacts and significant risks to human health and the environment." Among the 17 principles were #3 ("The EPA works to understand definitions of human health and the environment from the perspective of federally recognized tribes, indigenous peoples throughout the United States, and others living in Indian country"); #6 ("The EPA encourages, as appropriate and to the extent practicable and permitted by law, the integration of traditional ecological knowledge into the agency's environmental science, policy, and decision-making processes, to understand and address environmental justice concerns and facilitate program implementation"); and #7 ("The EPA considers confidentiality concerns regarding information on sacred sites, cultural resources, and other traditional knowledge, as permitted by law."). While this policy identifies guidelines and procedures for the EPA in regards to environmental justice principles as they relate to tribes and indigenous peoples, the agency noted that they are in no way applicable as rules or regulations. They cannot be applied to particular situations nor change or substitute any law, regulation, or any other legally-binding requirement and is not legally enforceable.

Personal development

Personal development or self-improvement consists of activities that develop a person's capabilities and potential, enhance quality of life, and facilitate the realization of dreams and aspirations. Personal development may take place over the course of an individual's entire lifespan and is not limited to one stage of a person's life. It can include official and informal actions for developing others in roles such as teacher, guide, counselor, manager, coach, or mentor, and it is not restricted to self-help. When personal development takes place in the context of institutions, it refers to the methods, programs, tools, techniques, and assessment systems offered to support positive adult development at the individual level in organizations. Overview Among other things, personal development may include the following activities: Social entrepreneurship or civic engagement Participating in festivals, conferences, or conventions Improving self-awareness Improving self-knowledge Improving skills and/or learning new ones Building or renewing identity/self-esteem Developing strengths or talents Improving a career Identifying or improving potential Building employability or (alternatively) human capital Enhancing lifestyle and/or the quality of life and time management calculating the return on time invested. Improving health Improving wealth or social status Fulfilling aspirations Initiating a life enterprise Defining and executing personal development plans (PDPs) Improving social relations or emotional intelligence Spiritual identity development and recognition A distinction can be made between personal development and personal growth. Although similar, both concepts portray different ideas. Personal development specifies the focus of the "what" that is evolving, while personal growth entails a much more holistic view of broader concepts including morals and values being developed. Personal development can also include developing other people's skills and personalities.This can happen through roles such as those of a teacher or mentor, either through a personal competency (such as the alleged skill of certain managers in developing the potential of employees) or through a professional service (such as providing training, assessment, or coaching). Beyond improving oneself and developing others, "personal development" labels a field of practice and research: As a field of practice, personal development includes personal-development methods, learning programs, assessment systems, tools, and techniques. As a field of research, personal-development topics appear in psychology journals, education research, management journals and books, and human-development economics. Any sort of development—whether economic, political, biological, organizational or personal—requires a framework if one wishes to know whether a change has actually occurred. In the case of personal development, an individual often functions as the primary judge of improvement or of regression, but the validation of objective improvement requires assessment using standard criteria. Personal-development frameworks may include: Goals or benchmarks that define the end-points Strategies or plans for reaching goals Measurement and assessment of progress, levels or stages that define milestones along a development path A feedback system to provide information on changes As an industry Personal development as an industry has several business-relationship formats of operating. The main ways are business-to-consumer and business-to-business. However, there have been two new ways emerge: consumer-to-business and consumer-to-consumer. The personal development market had a global market size of 38.28 billion dollars in 2019. Business-to-consumer market A wide array of personal development products are available to individuals. Examples include self-help books; education technology, neuroenhancement, and experiential learning (instructor-led training, motivational speeches, seminars, social or spiritual retreats). Domains Higher education, cognitive training Personal finance Weight loss, physical fitness, nutrition, and beauty enhancement Large-group awareness training Sensory deprivation Time-management Yoga Martial arts Initiation ceremonies Meditation Asceticism General methods of personal development also include: Life coaching or counseling Recommendation systems Nootropics, such as caffeinated drinks Brain computer interface Virtual assistant Business-to-business market Some consulting firms such as DDI and FranklinCovey specialize in personal development, but generalist firms operating in the fields of human resources, recruitment and organizational strategy—such as Hewitt, Watson Wyatt Worldwide, Hay Group, McKinsey, Boston Consulting Group, and Korn/Ferry—have entered what they perceive as a growing market, not to mention smaller firms and self-employed professionals who provide consulting, training and coaching. Origins Major religions—such as the age-old Abrahamic and Indian religions—as well as 20th-century New Age philosophies have variously used practices such as prayer, music, dance, singing, chanting, poetry, writing, sports and martial arts. Michel Foucault describes in Care of the Self the techniques of epimelia used in ancient Greece and Rome, which included dieting, exercise, sexual abstinence, contemplation, prayer, and confession—some of which also became practices within different branches of Christianity. Wushu and tai chi utilize traditional Chinese techniques, including breathing and qi exercises, meditation, martial arts, as well as practices linked to traditional Chinese medicine, such as dieting, massage, and acupuncture. Two individual ancient philosophical traditions: those of Aristotle (Western tradition) and Confucius (Eastern tradition) stand out and contribute to the worldwide view of "personal development" in the 21st century. Elsewhere anonymous or named founders of schools of self-development appear endemic—note the traditions of the Indian sub-continent in this regard. South Asian traditions Some ancient Indians aspired to "beingness, wisdom and happiness". Paul Oliver suggests that the popularity of Indian traditions for a personal developer may lie in their relative lack of prescriptive doctrine. Islamic personal development Khurram Murad describes that personal development in Islam is to work towards eternal life in Jannuh. There are many avenues in the journey to paradise, such as devoted practicing of the laws of the Quran and Sunnah, such as optimized service towards the self and others. Sincere worship of Allah is the foundation for self-discovery and self-development. Allah has provided ways to help those striving towards eternal life, including staying away from things of the world. These worldly things can distract those away from the path to paradise. It does not mean worldly success is inherently disruptive but can become so when spiritual beliefs do not align with the Sunnah. In the end, paradise will bring satisfaction to those working on their personal development because of the pleasure that comes from Allah. Aristotle and the Western tradition The Greek philosopher Aristotle (384 BCE322 BCE) wrote Nicomachean Ethics, in which he defined personal development as a category of phronesis or practical wisdom, where the practice of virtues (arête) leads to eudaimonia, commonly translated as "happiness" but more accurately understood as "human flourishing" or "living well". Aristotle continues to influence the Western concept of personal development , particularly in the economics of human development and in positive psychology. Confucius and the East Asian tradition In Chinese tradition, Confucius (around 551 BCE479 BCE) founded an ongoing philosophy. His ideas continue to influence family values, education and personnel management in China and East Asia. In his Great Learning Confucius wrote: Contexts Psychology Psychology became linked to personal development in the early 20th century starting with the research efforts of Alfred Adler (1870–1937) and Carl Jung (1875–1961). Adler refused to limit psychology to analysis alone. He made the important point that aspirations focus on looking forward and do not limit themselves to unconscious drives or to childhood experiences. He also originated the concepts of lifestyle (1929—he defined "lifestyle" as an individual's characteristic approach to life, in facing problems) and of self-image, as a concept that influenced management under the heading of work-life balance, also known as the equilibrium between a person's career and personal life. Carl Gustav Jung made contributions to personal development with his concept of individuation, which he saw as the drive of the individual to achieve the wholeness and balance of the Self. Daniel Levinson (1920–1994) developed Jung's early concept of "life stages" and included a sociological perspective. Levinson proposed that personal development comes under the influence—throughout life—of aspirations, which he called "the Dream": Research on success in reaching goals, as undertaken by Albert Bandura (1925–2021), suggested that self-efficacy best explains why people with the same level of knowledge and skills get very different results. Having self-efficacy leads to an increased likelihood of success. According to Bandura self-confidence functions as a powerful predictor of success because: It causes you to expect to succeed It allows you take risks and set challenging goals It helps you keep trying if at first you do not succeed It helps you control emotions and fears when life may throw more difficult things your way In 1998 Martin Seligman won election to a one-year term as President of the American Psychological Association and proposed a new focus: on healthy individuals rather than on pathology (he created the "positive psychology" current) Carl Rogers proposed a theory about humanistic psychology called Self Concept. This concept consisted of two ideas of the self. The first idea is the ideal self which describes the person we want to be. The second one is the real self which is the objective view of one self and who we really are. Rogers emphasized that healthy development is when the real self and the ideal self are accurate. Incongruence is what Rogers described to be when the real self and the ideal self are not accurate in their viewings. The ideal self is not lowered in order to compensate for the real self, but the real self is lifted by the ideal self in order to achieve healthy development. It is important to note that real lasting personal development is only achieved through meaningful and lasting accomplishments. Viktor Frankl emphasized this by stating "Genuine and lasting well-being is the result of a “life well-lived”. In an article written by Ugur, H., Constantinescu, P.M., & Stevens, M.J. (2015) they described that society has taught us to create positive illusions that give the appearance of positive development but are only effective in the short term. Additionally, they give two examples of personal development. The first is hedonic well-being which is the pursuit of pleasurable experiences that lead to increased personal happiness. The second is eudaimonic well-being which is living life by making choices that are congruent with authentic being. Social psychology Social psychology heavily emphasizes and focuses on human behavior and how individuals interact with others in society. Infants develop socially by creating trusting and dependent relationships with others—namely parental figures. They learn how to act and treat other people based on the example of parental figures and other adults they interact with often. Toddlers further develop social skills. Additionally, they begin to gain a desire for autonomy and grow more and more independent as they grow older. The balance of social involvement and autonomy varies per person, but normally autonomous behavior increases with age. Some studies suggest that selfishness begins to diminish, and prosocial behaviors increase, between the ages of six years old to twelve years old. Additionally, the years of adulthood are times of development—self-actualization, relational and occupational development, loss, and coping skills development, etc.—affected by those around us: parents, co-workers, romantic partners, and children. Social psychology draws from many other psychological theories and principles yet views them through a lens of social interaction. Psychodynamic psychology The psychodynamic view of personal development varies from other perspectives. Namely, that the development of our traits, personalities, and thinking patterns are predominantly subconscious. Psychodynamic theory suggests these subconscious changes—which emerge as external actions—are formed from suppressed sexual and aggressive urges and other internalized conflicts. Sigmund Freud and other notable psychodynamic theorists postulate that these repressed cognitions form during childhood and adolescence. Conscious development would then be "digging up" these repressed memories and feelings. Once repressed memories and emotions are discovered, an individual can sift through them and receive healthy closure. Much, if not all, of conscious development occurs with the aid of a trained psychodynamic therapist. Cognitive-behavioral psychology Cognitive-behavioral views on personal development follow traditional patterns of personal development: behavior modification, cognitive reframing, and successive approximation being some of the more notable techniques. An individual is seen as in control of their actions and their thoughts, though self-mastery is required. With behavior modification, individuals will develop personal skills and traits by altering their behavior independent of their emotions. For example, a person may feel intense anger but would still behave in a positive manner. They are able to suppress their emotions and act in a more socially acceptable way. The accumulation of these efforts would change the person into a more patient individual. Cognitive reframing plays an instrumental role in personal development. Cognitive-behavioral psychologists believe that how we view events is more important than the event itself. Thus, if one can view negative events in beneficial ways, they can progress and develop with fewer setbacks. Successive approximation—or shaping—most closely aligns with personal development. Successive approximation is when one desires a final result but takes incremental steps to achieve the result. Normally, each successful step towards the final goal is rewarded until the goal is achieved. Personal development, if it is to be long-lasting, is achieved incrementally. Educational psychology Educational psychology focuses on the human learning experience: learning and teaching methods, aptitude testing, and so on. Educational psychology seeks to further personal development by increasing one's ability to learn, retain information, and apply knowledge to real-world experiences. If one is able to increase efficacious learning, they are better equipped for personal development. Early education Education offers children the opportunity to begin personal development at a young age. The curriculum taught at school must be carefully planned and managed in order to successfully promote personal development. Providing an environment for children that allows for quality social relationships to be made and clearly communicated objectives and aims is key to their development. If early education fails to meet these qualifications, it can greatly stunt development in children, hindering their success in education as well as society. They can fall behind in development compared to peers of the same age group. Higher education During the 1960s a large increase in the number of students on American campuses led to research on the personal development needs of undergraduate students. Arthur Chickering defined seven vectors of personal development for young adults during their undergraduate years: Developing competence Managing emotions Achieving autonomy and interdependence Developing mature interpersonal relationships Establishing personal identity Developing purpose Developing integrity In the UK, personal development took a central place in university policy in 1997 when the Dearing Report declared that universities should go beyond academic teaching to provide students with personal development. In 2001 a Quality Assessment Agency for UK universities produced guidelines for universities to enhance personal development as: a structured and supported process undertaken by an individual to reflect upon their own learning, performance and/or achievement and to plan for their personal, educational and career development; objectives related explicitly to student development; to improve the capacity of students to understand what and how they are learning, and to review, plan and take responsibility for their own learning In the 1990s, business schools began to set up specific personal-development programs for leadership and career orientation and in 1998 the European Foundation for Management Development set up the EQUIS accreditation system which specified that personal development must form part of the learning process through internships, working on team projects and going abroad for work or exchange programs. The first personal development certification required for business school graduation originated in 2002 as a partnership between Metizo, a personal-development consulting firm, and the Euromed Management School in Marseilles: students must not only complete assignments but also demonstrate self-awareness and achievement of personal-development competencies. As an academic department, personal development as a specific discipline is often associated with business schools. As an area of research, personal development draws on links to other academic disciplines: Education for questions of learning and assessment Psychology for motivation and personality Sociology for identity and social networks Economics for human capital and economic value Philosophy for ethics and self-reflection Developmental activities Personal Development can include gaining self-awareness of the course of one's lifespan. It includes multiple definitions but is different from self knowledge. Self-awareness is more in depth and explores the conscious and unconscious aspects of ourselves. We are able to gain self-awareness through socializing and communicating according to the social behaviorism view. Self-awareness can also be a positive intrapersonal experience where one is able to reflect during a moment of action or past actions. Becoming more self aware can help us to increase our emotional intelligence, leadership skills, and performance. The workplace Abraham Maslow (1908–1970), proposed a hierarchy of needs with self actualization at the top, defined as "the desire to become more and more what one is, to become everything that one is capable of becoming". In other words, self actualization is the ambition to become a better version of oneself, to become everything one is capable of being. Since Maslow himself believed that only a small minority of people self-actualize—he estimated one percent—his hierarchy of needs had the consequence that organizations came to regard self-actualization or personal development as occurring at the top of the organizational pyramid, while openness and job security in the workplace would fulfill the needs of the mass of employees. As organizations and labor markets became more global, responsibility for development shifted from the company to the individual. In 1999 management thinker Peter Drucker wrote in the Harvard Business Review: Management professors Sumantra Ghoshal of the London Business School and Christopher Bartlett of the Harvard Business School wrote in 1997 that companies must manage people individually and establish a new work contract. On the one hand, the company must allegedly recognize that personal development creates economic value: "market performance flows not from the omnipotent wisdom of top managers but from the initiative, creativity and skills of all employees". On the other hand, employees should recognize that their work includes personal development and "embrace the invigorating force of continuous learning and personal development". The 1997 publication of Ghoshal's and Bartlett's Individualized Corporation corresponded to a change in career development from a system of predefined paths defined by companies, to a strategy defined by the individual and matched to the needs of organizations in an open landscape of possibilities. Another contribution to the study of career development came with the recognition that women's careers show specific personal needs and different development paths from men. The 2007 study of women's careers by Sylvia Ann Hewlett Off-Ramps and On-Ramps had a major impact on the way companies view careers. Further work on the career as a personal development process came from study by Herminia Ibarra in her Working Identity on the relationship with career change and identity change, indicating that priorities of work and lifestyle continually develop through life. Personal development programs in companies fall into two categories: the provision of employee benefits and the fostering of development strategies. Employee surveys may help organizations find out personal-development needs, preferences and problems, and they use the results to design benefits programs. Typical programs in this category include: Work-life balance Time management Stress management Health programs Counseling As an investment, personal development programs have the goal of increasing human capital or improving productivity, innovation or quality. Proponents actually see such programs not as a cost but as an investment with results linked to an organization's strategic development goals. Employees gain access to these investment-oriented programs by selection according to the value and future potential of the employee, usually defined in a talent management architecture including populations such as new hires, perceived high-potential employees, perceived key employees, sales staff, research staff and perceived future leaders. Organizations may also offer other (non-investment-oriented) programs to many or even all employees. Personal development also forms an element in management tools such as personal development planning, assessing one's level of ability using a competency grid, or getting feedback from a 360 questionnaire filled in by colleagues at different levels in the organization. A common criticism surrounding personal development programs is that they are often treated as an arbitrary performance management tool to pay lip service to, but ultimately ignored. As such, many companies have decided to replace personal development programs with SMART Personal Development Objectives, which are regularly reviewed and updated. Personal Development Objectives help employees achieve career goals and improve overall performance. Criticism Scholars have targeted self-help claims as misleading and incorrect. In 2005, Steve Salerno portrayed the American self-help movement—he uses the acronym "SHAM": the "Self-Help and Actualization Movement"—not only as ineffective in achieving its goals but also as socially harmful, and that self-help customers keep investing more money in these services regardless of their effectiveness. Others similarly point out that with self-help books "supply increases the demand ... The more people read them, the more they think they need them ... more like an addiction than an alliance". Self-help writers have been described as working "in the area of the ideological, the imagined, the narrativized. ... although a veneer of scientism permeates the[ir] work, there is also an underlying armature of moralizing".

Energy flow (ecology)

Energy flow is the flow of energy through living things within an ecosystem. All living organisms can be organized into producers and consumers, and those producers and consumers can further be organized into a food chain. Each of the levels within the food chain is a trophic level. In order to more efficiently show the quantity of organisms at each trophic level, these food chains are then organized into trophic pyramids. The arrows in the food chain show that the energy flow is unidirectional, with the head of an arrow indicating the direction of energy flow; energy is lost as heat at each step along the way. The unidirectional flow of energy and the successive loss of energy as it travels up the food web are patterns in energy flow that are governed by thermodynamics, which is the theory of energy exchange between systems. Trophic dynamics relates to thermodynamics because it deals with the transfer and transformation of energy (originating externally from the sun via solar radiation) to and among organisms. Energetics and the carbon cycle The first step in energetics is photosynthesis, where in water and carbon dioxide from the air are taken in with energy from the sun, and are converted into oxygen and glucose. Cellular respiration is the reverse reaction, wherein oxygen and sugar are taken in and release energy as they are converted back into carbon dioxide and water. The carbon dioxide and water produced by respiration can be recycled back into plants. Energy loss can be measured either by efficiency (how much energy makes it to the next level), or by biomass (how much living material exists at those levels at one point in time, measured by standing crop). Of all the net primary productivity at the producer trophic level, in general only 10% goes to the next level, the primary consumers, then only 10% of that 10% goes on to the next trophic level, and so on up the food pyramid. Ecological efficiency may be anywhere from 5% to 20% depending on how efficient or inefficient that ecosystem is. This decrease in efficiency occurs because organisms need to perform cellular respiration to survive, and energy is lost as heat when cellular respiration is performed. That is also why there are fewer tertiary consumers than there are producers. Primary production A producer is any organism that performs photosynthesis. Producers are important because they convert energy from the sun into a storable and usable chemical form of energy, glucose, as well as oxygen. The producers themselves can use the energy stored in glucose to perform cellular respiration. Or, if the producer is consumed by herbivores in the next trophic level, some of the energy is passed on up the pyramid. The glucose stored within producers serves as food for consumers, and so it is only through producers that consumers are able to access the sun’s energy. Some examples of primary producers are algae, mosses, and other plants such as grasses, trees, and shrubs. Chemosynthetic bacteria perform a process similar to photosynthesis, but instead of energy from the sun they use energy stored in chemicals like hydrogen sulfide. This process, referred to as chemosynthesis, usually occurs deep in the ocean at hydrothermal vents that produce heat and chemicals such as hydrogen, hydrogen sulfide and methane. Chemosynthetic bacteria can use the energy in the bonds of the hydrogen sulfide and oxygen to convert carbon dioxide to glucose, releasing water and sulfur in the process. Organisms that consume the chemosynthetic bacteria can take in the glucose and use oxygen to perform cellular respiration, similar to herbivores consuming producers. One of the factors that controls primary production is the amount of energy that enters the producer(s), which can be measured using productivity. Only one percent of solar energy enters the producer, the rest bounces off or moves through. Gross primary productivity is the amount of energy the producer actually gets. Generally, 60% of the energy that enters the producer goes to the producer’s own respiration. The net primary productivity is the amount that the plant retains after the amount that it used for cellular respiration is subtracted. Another factor controlling primary production is organic/inorganic nutrient levels in the water or soil that the producer is living in. Secondary production Secondary production is the use of energy stored in plants converted by consumers to their own biomass. Different ecosystems have different levels of consumers, all end with one top consumer. Most energy is stored in organic matter of plants, and as the consumers eat these plants they take up this energy. This energy in the herbivores and omnivores is then consumed by carnivores. There is also a large amount of energy that is in primary production and ends up being waste or litter, referred to as detritus. The detrital food chain includes a large amount of microbes, macroinvertebrates, meiofauna, fungi, and bacteria. These organisms are consumed by omnivores and carnivores and account for a large amount of secondary production. Secondary consumers can vary widely in how efficient they are in consuming. The efficiency of energy being passed on to consumers is estimated to be around 10%. Energy flow through consumers differs in aquatic and terrestrial environments. In aquatic environments Heterotrophs contribute to secondary production and it is dependent on primary productivity and the net primary products. Secondary production is the energy that herbivores and decomposers use and thus depends on primary productivity. Primarily herbivores and decomposers consume all the carbon from two main organic sources in aquatic ecosystems, autochthonous and allochthonous. Autochthonous carbon comes from within the ecosystem and includes aquatic plants, algae and phytoplankton. Allochthonous carbon from outside the ecosystem is mostly dead organic matter from the terrestrial ecosystem entering the water. In stream ecosystems, approximately 66% of annual energy input can be washed downstream. The remaining amount is consumed and lost as heat. In terrestrial environments Secondary production is often described in terms of trophic levels, and while this can be useful in explaining relationships it overemphasizes the rarer interactions. Consumers often feed at multiple trophic levels. Energy transferred above the third trophic level is relatively unimportant. The assimilation efficiency can be expressed by the amount of food the consumer has eaten, how much the consumer assimilates and what is expelled as feces or urine. While a portion of the energy is used for respiration, another portion of the energy goes towards biomass in the consumer. There are two major food chains: The primary food chain is the energy coming from autotrophs and passed on to the consumers; and the second major food chain is when carnivores eat the herbivores or decomposers that consume the autotrophic energy. Consumers are broken down into primary consumers, secondary consumers and tertiary consumers. Carnivores have a much higher assimilation of energy, about 80% and herbivores have a much lower efficiency of approximately 20 to 50%. Energy in a system can be affected by animal emigration/immigration. The movements of organisms are significant in terrestrial ecosystems. Energetic consumption by herbivores in terrestrial ecosystems has a low range of ~3-7%. The flow of energy is similar in many terrestrial environments. The fluctuation in the amount of net primary product consumed by herbivores is generally low. This is in large contrast to aquatic environments of lakes and ponds where grazers have a much higher consumption of around ~33%. Ectotherms and endotherms have very different assimilation efficiencies. Detritivores Detritivores consume organic material that is decomposing and are in turn consumed by carnivores. Predator productivity is correlated with prey productivity. This confirms that the primary productivity in ecosystems affects all productivity following. Detritus is a large portion of organic material in ecosystems. Organic material in temperate forests is mostly made up of dead plants, approximately 62%. In an aquatic ecosystem, leaf matter that falls into streams gets wet and begins to leech organic material. This happens rather quickly and will attract microbes and invertebrates. The leaves can be broken down into large pieces called coarse particulate organic matter (CPOM). The CPOM is rapidly colonized by microbes. Meiofauna is extremely important to secondary production in stream ecosystems. Microbes breaking down and colonizing this leaf matter are very important to the detritovores. The detritovores make the leaf matter more edible by releasing compounds from the tissues; it ultimately helps soften them. As leaves decay nitrogen will decrease since cellulose and lignin in the leaves is difficult to break down. Thus the colonizing microbes bring in nitrogen in order to aid in the decomposition. Leaf breakdown can depend on initial nitrogen content, season, and species of trees. The species of trees can have variation when their leaves fall. Thus the breakdown of leaves is happening at different times, which is called a mosaic of microbial populations. Species effect and diversity in an ecosystem can be analyzed through their performance and efficiency. In addition, secondary production in streams can be influenced heavily by detritus that falls into the streams; production of benthic fauna biomass and abundance decreased an additional 47–50% during a study of litter removal and exclusion. Energy flow across ecosystems Research has demonstrated that primary producers fix carbon at similar rates across ecosystems. Once carbon has been introduced into a system as a viable source of energy, the mechanisms that govern the flow of energy to higher trophic levels vary across ecosystems. Among aquatic and terrestrial ecosystems, patterns have been identified that can account for this variation and have been divided into two main pathways of control: top-down and bottom-up. The acting mechanisms within each pathway ultimately regulate community and trophic level structure within an ecosystem to varying degrees. Bottom-up controls involve mechanisms that are based on resource quality and availability, which control primary productivity and the subsequent flow of energy and biomass to higher trophic levels. Top-down controls involve mechanisms that are based on consumption by consumers. These mechanisms control the rate of energy transfer from one trophic level to another as herbivores or predators feed on lower trophic levels. Aquatic vs terrestrial ecosystems Much variation in the flow of energy is found within each type of ecosystem, creating a challenge in identifying variation between ecosystem types. In a general sense, the flow of energy is a function of primary productivity with temperature, water availability, and light availability. For example, among aquatic ecosystems, higher rates of production are usually found in large rivers and shallow lakes than in deep lakes and clear headwater streams. Among terrestrial ecosystems, marshes, swamps, and tropical rainforests have the highest primary production rates, whereas tundra and alpine ecosystems have the lowest. The relationships between primary production and environmental conditions have helped account for variation within ecosystem types, allowing ecologists to demonstrate that energy flows more efficiently through aquatic ecosystems than terrestrial ecosystems due to the various bottom-up and top-down controls in play. Bottom-up The strength of bottom-up controls on energy flow are determined by the nutritional quality, size, and growth rates of primary producers in an ecosystem. Photosynthetic material is typically rich in nitrogen (N) and phosphorus (P) and supplements the high herbivore demand for N and P across all ecosystems. Aquatic primary production is dominated by small, single-celled phytoplankton that are mostly composed of photosynthetic material, providing an efficient source of these nutrients for herbivores. In contrast, multi-cellular terrestrial plants contain many large supporting cellulose structures of high carbon but low nutrient value. Because of this structural difference, aquatic primary producers have less biomass per photosynthetic tissue stored within the aquatic ecosystem than in the forests and grasslands of terrestrial ecosystems. This low biomass relative to photosynthetic material in aquatic ecosystems allows for a more efficient turnover rate compared to terrestrial ecosystems. As phytoplankton are consumed by herbivores, their enhanced growth and reproduction rates sufficiently replace lost biomass and, in conjunction with their nutrient dense quality, support greater secondary production. Additional factors impacting primary production includes inputs of N and P, which occurs at a greater magnitude in aquatic ecosystems. These nutrients are important in stimulating plant growth and, when passed to higher trophic levels, stimulate consumer biomass and growth rate. If either of these nutrients are in short supply, they can limit overall primary production. Within lakes, P tends to be the greater limiting nutrient while both N and P limit primary production in rivers. Due to these limiting effects, nutrient inputs can potentially alleviate the limitations on net primary production of an aquatic ecosystem. Allochthonous material washed into an aquatic ecosystem introduces N and P as well as energy in the form of carbon molecules that are readily taken up by primary producers. Greater inputs and increased nutrient concentrations support greater net primary production rates, which in turn supports greater secondary production. Top-down Top-down mechanisms exert greater control on aquatic primary producers due to the roll of consumers within an aquatic food web. Among consumers, herbivores can mediate the impacts of trophic cascades by bridging the flow of energy from primary producers to predators in higher trophic levels. Across ecosystems, there is a consistent association between herbivore growth and producer nutritional quality. However, in aquatic ecosystems, primary producers are consumed by herbivores at a rate four times greater than in terrestrial ecosystems. Although this topic is highly debated, researchers have attributed the distinction in herbivore control to several theories, including producer to consumer size ratios and herbivore selectivity. Modeling of top-down controls on primary producers suggests that the greatest control on the flow of energy occurs when the size ratio of consumer to primary producer is the highest. The size distribution of organisms found within a single trophic level in aquatic systems is much narrower than that of terrestrial systems. On land, the consumer size ranges from smaller than the plant it consumes, such as an insect, to significantly larger, such as an ungulate, while in aquatic systems, consumer body size within a trophic level varies much less and is strongly correlated with trophic position. As a result, the size difference between producers and consumers is consistently larger in aquatic environments than on land, resulting in stronger herbivore control over aquatic primary producers. Herbivores can potentially control the fate of organic matter as it is cycled through the food web. Herbivores tend to select nutritious plants while avoiding plants with structural defense mechanisms. Like support structures, defense structures are composed of nutrient poor, high carbon cellulose. Access to nutritious food sources enhances herbivore metabolism and energy demands, leading to greater removal of primary producers. In aquatic ecosystems, phytoplankton are highly nutritious and generally lack defense mechanisms. This results in greater top-down control because consumed plant matter is quickly released back into the system as labile organic waste. In terrestrial ecosystems, primary producers are less nutritionally dense and are more likely to contain defense structures. Because herbivores prefer nutritionally dense plants and avoid plants or plant parts with defense structures, a greater amount of plant matter is left unconsumed within the ecosystem. Herbivore avoidance of low-quality plant matter may be why terrestrial systems exhibit weaker top-down control on the flow of energy.

Environmental science

Environmental science is an interdisciplinary academic field that integrates physics, biology, meteorology, mathematics and geography (including ecology, chemistry, plant science, zoology, mineralogy, oceanography, limnology, soil science, geology and physical geography, and atmospheric science) to the study of the environment, and the solution of environmental problems. Environmental science emerged from the fields of natural history and medicine during the Enlightenment. Today it provides an integrated, quantitative, and interdisciplinary approach to the study of environmental systems. Environmental studies incorporates more of the social sciences for understanding human relationships, perceptions and policies towards the environment. Environmental engineering focuses on design and technology for improving environmental quality in every aspect. Environmental scientists seek to understand the earth's physical, chemical, biological, and geological processes, and to use that knowledge to understand how issues such as alternative energy systems, pollution control and mitigation, natural resource management, and the effects of global warming and climate change influence and affect the natural systems and processes of earth. Environmental issues almost always include an interaction of physical, chemical, and biological processes. Environmental scientists bring a systems approach to the analysis of environmental problems. Key elements of an effective environmental scientist include the ability to relate space, and time relationships as well as quantitative analysis. Environmental science came alive as a substantive, active field of scientific investigation in the 1960s and 1970s driven by (a) the need for a multi-disciplinary approach to analyze complex environmental problems, (b) the arrival of substantive environmental laws requiring specific environmental protocols of investigation and (c) the growing public awareness of a need for action in addressing environmental problems. Events that spurred this development included the publication of Rachel Carson's landmark environmental book Silent Spring along with major environmental issues becoming very public, such as the 1969 Santa Barbara oil spill, and the Cuyahoga River of Cleveland, Ohio, "catching fire" (also in 1969), and helped increase the visibility of environmental issues and create this new field of study. Terminology In common usage, "environmental science" and "ecology" are often used interchangeably, but technically, ecology refers only to the study of organisms and their interactions with each other as well as how they interrelate with environment. Ecology could be considered a subset of environmental science, which also could involve purely chemical or public health issues (for example) ecologists would be unlikely to study. In practice, there are considerable similarities between the work of ecologists and other environmental scientists. There is substantial overlap between ecology and environmental science with the disciplines of fisheries, forestry, and wildlife. History Ancient civilizations Historical concern for environmental issues is well documented in archives around the world. Ancient civilizations were mainly concerned with what is now known as environmental science insofar as it related to agriculture and natural resources. Scholars believe that early interest in the environment began around 6000 BCE when ancient civilizations in Israel and Jordan collapsed due to deforestation. As a result, in 2700 BCE the first legislation limiting deforestation was established in Mesopotamia. Two hundred years later, in 2500 BCE, a community residing in the Indus River Valley observed the nearby river system in order to improve sanitation. This involved manipulating the flow of water to account for public health. In the Western Hemisphere, numerous ancient Central American city-states collapsed around 1500 BCE due to soil erosion from intensive agriculture. Those remaining from these civilizations took greater attention to the impact of farming practices on the sustainability of the land and its stable food production. Furthermore, in 1450 BCE the Minoan civilization on the Greek island of Crete declined due to deforestation and the resulting environmental degradation of natural resources. Pliny the Elder somewhat addressed the environmental concerns of ancient civilizations in the text Naturalis Historia, written between 77 and 79 ACE, which provided an overview of many related subsets of the discipline. Although warfare and disease were of primary concern in ancient society, environmental issues played a crucial role in the survival and power of different civilizations. As more communities recognized the importance of the natural world to their long-term success, an interest in studying the environment came into existence. Beginnings of environmental science 18th century In 1735, the concept of binomial nomenclature is introduced by Carolus Linnaeus as a way to classify all living organisms, influenced by earlier works of Aristotle. His text, Systema Naturae, represents one of the earliest culminations of knowledge on the subject, providing a means to identify different species based partially on how they interact with their environment. 19th century In the 1820s, scientists were studying the properties of gases, particularly those in the Earth's atmosphere and their interactions with heat from the Sun. Later that century, studies suggested that the Earth had experienced an Ice Age and that warming of the Earth was partially due to what are now known as greenhouse gases (GHG). The greenhouse effect was introduced, although climate science was not yet recognized as an important topic in environmental science due to minimal industrialization and lower rates of greenhouse gas emissions at the time. 20th century In the 1900s, the discipline of environmental science as it is known today began to take shape. The century is marked by significant research, literature, and international cooperation in the field. In the early 20th century, criticism from dissenters downplayed the effects of global warming. At this time, few researchers were studying the dangers of fossil fuels. After a 1.3 degrees Celsius temperature anomaly was found in the Atlantic Ocean in the 1940s, however, scientists renewed their studies of gaseous heat trapping from the greenhouse effect (although only carbon dioxide and water vapor were known to be greenhouse gases then). Nuclear development following the Second World War allowed environmental scientists to intensively study the effects of carbon and make advancements in the field. Further knowledge from archaeological evidence brought to light the changes in climate over time, particularly ice core sampling. Environmental science was brought to the forefront of society in 1962 when Rachel Carson published an influential piece of environmental literature, Silent Spring. Carson's writing led the American public to pursue environmental safeguards, such as bans on harmful chemicals like the insecticide DDT. Another important work, The Tragedy of the Commons, was published by Garrett Hardin in 1968 in response to accelerating natural degradation. In 1969, environmental science once again became a household term after two striking disasters: Ohio's Cuyahoga River caught fire due to the amount of pollution in its waters and a Santa Barbara oil spill endangered thousands of marine animals, both receiving prolific media coverage. Consequently, the United States passed an abundance of legislation, including the Clean Water Act and the Great Lakes Water Quality Agreement. The following year, in 1970, the first ever Earth Day was celebrated worldwide and the United States Environmental Protection Agency (EPA) was formed, legitimizing the study of environmental science in government policy. In the next two years, the United Nations created the United Nations Environment Programme (UNEP) in Stockholm, Sweden to address global environmental degradation. Much of the interest in environmental science throughout the 1970s and the 1980s was characterized by major disasters and social movements. In 1978, hundreds of people were relocated from Love Canal, New York after carcinogenic pollutants were found to be buried underground near residential areas. The next year, in 1979, the nuclear power plant on Three Mile Island in Pennsylvania suffered a meltdown and raised concerns about the dangers of radioactive waste and the safety of nuclear energy. In response to landfills and toxic waste often disposed of near their homes, the official Environmental Justice Movement was started by a Black community in North Carolina in 1982. Two years later, the toxic methyl isocyanate gas was released to the public from a power plant disaster in Bhopal, India, harming hundreds of thousands of people living near the disaster site, the effects of which are still felt today. In a groundbreaking discovery in 1985, a British team of researchers studying Antarctica found evidence of a hole in the ozone layer, inspiring global agreements banning the use of chlorofluorocarbons (CFCs), which were previously used in nearly all aerosols and refrigerants. Notably, in 1986, the meltdown at the Chernobyl nuclear power plant in Ukraine released radioactive waste to the public, leading to international studies on the ramifications of environmental disasters. Over the next couple of years, the Brundtland Commission (previously known as the World Commission on Environment and Development) published a report titled Our Common Future and the Montreal Protocol formed the International Panel on Climate Change (IPCC) as international communication focused on finding solutions for climate change and degradation. In the late 1980s, the Exxon Valdez company was fined for spilling large quantities of crude oil off the coast of Alaska and the resulting cleanup, involving the work of environmental scientists. After hundreds of oil wells were burned in combat in 1991, warfare between Iraq and Kuwait polluted the surrounding atmosphere just below the air quality threshold s believed was life-threatening. 21st century Many niche disciplines of environmental science have emerged over the years, although climatology is one of the most known topics. Since the 2000s, environmental scientists have focused on modeling the effects of climate change and encouraging global cooperation to minimize potential damages. In 2002, the Society for the Environment as well as the Institute of Air Quality Management were founded to share knowledge and develop solutions around the world. Later, in 2008, the United Kingdom became the first country to pass legislation (the Climate Change Act) that aims to reduce carbon dioxide output to a specified threshold. In 2016 the Kyoto Protocol became the Paris Agreement, which sets concrete goals to reduce greenhouse gas emissions and restricts Earth's rise in temperature to a 2 degrees Celsius maximum. The agreement is one of the most expansive international efforts to limit the effects of global warming to date. Most environmental disasters in this time period involve crude oil pollution or the effects of rising temperatures. In 2010, BP was responsible for the largest American oil spill in the Gulf of Mexico, known as the Deepwater Horizon spill, which killed a number of the company's workers and released large amounts of crude oil into the water. Furthermore, throughout this century, much of the world has been ravaged by widespread wildfires and water scarcity, prompting regulations on the sustainable use of natural resources as determined by environmental scientists. The 21st century is marked by significant technological advancements. New technology in environmental science has transformed how researchers gather information about various topics in the field. Research in engines, fuel efficiency, and decreasing emissions from vehicles since the times of the Industrial Revolution has reduced the amount of carbon and other pollutants into the atmosphere. Furthermore, investment in researching and developing clean energy (i.e. wind, solar, hydroelectric, and geothermal power) has significantly increased in recent years, indicating the beginnings of the divestment from fossil fuel use. Geographic information systems (GIS) are used to observe sources of air or water pollution through satellites and digital imagery analysis. This technology allows for advanced farming techniques like precision agriculture as well as monitoring water usage in order to set market prices. In the field of water quality, developed strains of natural and manmade bacteria contribute to bioremediation, the treatment of wastewaters for future use. This method is more eco-friendly and cheaper than manual cleanup or treatment of wastewaters. Most notably, the expansion of computer technology has allowed for large data collection, advanced analysis, historical archives, public awareness of environmental issues, and international scientific communication. The ability to crowdsource on the Internet, for example, represents the process of collectivizing knowledge from researchers around the world to create increased opportunity for scientific progress. With crowdsourcing, data is released to the public for personal analyses which can later be shared as new information is found. Another technological development, blockchain technology, monitors and regulates global fisheries. By tracking the path of fish through global markets, environmental scientists can observe whether certain species are being overharvested to the point of extinction. Additionally, remote sensing allows for the detection of features of the environment without physical intervention. The resulting digital imagery is used to create increasingly accurate models of environmental processes, climate change, and much more. Advancements to remote sensing technology are particularly useful in locating the nonpoint sources of pollution and analyzing ecosystem health through image analysis across the electromagnetic spectrum. Lastly, thermal imaging technology is used in wildlife management to catch and discourage poachers and other illegal wildlife traffickers from killing endangered animals, proving useful for conservation efforts. Artificial intelligence has also been used to predict the movement of animal populations and protect the habitats of wildlife. Components Atmospheric sciences Atmospheric sciences focus on the Earth's atmosphere, with an emphasis upon its interrelation to other systems. Atmospheric sciences can include studies of meteorology, greenhouse gas phenomena, atmospheric dispersion modeling of airborne contaminants, sound propagation phenomena related to noise pollution, and even light pollution. Taking the example of the global warming phenomena, physicists create computer models of atmospheric circulation and infrared radiation transmission, chemists examine the inventory of atmospheric chemicals and their reactions, biologists analyze the plant and animal contributions to carbon dioxide fluxes, and specialists such as meteorologists and oceanographers add additional breadth in understanding the atmospheric dynamics. Ecology As defined by the Ecological Society of America, "Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them." Ecologists might investigate the relationship between a population of organisms and some physical characteristic of their environment, such as concentration of a chemical; or they might investigate the interaction between two populations of different organisms through some symbiotic or competitive relationship. For example, an interdisciplinary analysis of an ecological system which is being impacted by one or more stressors might include several related environmental science fields. In an estuarine setting where a proposed industrial development could impact certain species by water and air pollution, biologists would describe the flora and fauna, chemists would analyze the transport of water pollutants to the marsh, physicists would calculate air pollution emissions and geologists would assist in understanding the marsh soils and bay muds. Environmental chemistry Environmental chemistry is the study of chemical alterations in the environment. Principal areas of study include soil contamination and water pollution. The topics of analysis include chemical degradation in the environment, multi-phase transport of chemicals (for example, evaporation of a solvent containing lake to yield solvent as an air pollutant), and chemical effects upon biota. As an example study, consider the case of a leaking solvent tank which has entered the habitat soil of an endangered species of amphibian. As a method to resolve or understand the extent of soil contamination and subsurface transport of solvent, a computer model would be implemented. Chemists would then characterize the molecular bonding of the solvent to the specific soil type, and biologists would study the impacts upon soil arthropods, plants, and ultimately pond-dwelling organisms that are the food of the endangered amphibian. Geosciences Geosciences include environmental geology, environmental soil science, volcanic phenomena and evolution of the Earth's crust. In some classification systems this can also include hydrology, including oceanography. As an example study, of soils erosion, calculations would be made of surface runoff by soil scientists. Fluvial geomorphologists would assist in examining sediment transport in overland flow. Physicists would contribute by assessing the changes in light transmission in the receiving waters. Biologists would analyze subsequent impacts to aquatic flora and fauna from increases in water turbidity. Regulations driving the studies In the United States the National Environmental Policy Act (NEPA) of 1969 set forth requirements for analysis of federal government actions (such as highway construction projects and land management decisions) in terms of specific environmental criteria. Numerous state laws have echoed these mandates, applying the principles to local-scale actions. The upshot has been an explosion of documentation and study of environmental consequences before the fact of development actions. One can examine the specifics of environmental science by reading examples of Environmental Impact Statements prepared under NEPA such as: Wastewater treatment expansion options discharging into the San Diego/Tijuana Estuary, Expansion of the San Francisco International Airport, Development of the Houston, Metro Transportation system, Expansion of the metropolitan Boston MBTA transit system, and Construction of Interstate 66 through Arlington, Virginia. In England and Wales the Environment Agency (EA), formed in 1996, is a public body for protecting and improving the environment and enforces the regulations listed on the communities and local government site. (formerly the office of the deputy prime minister). The agency was set up under the Environment Act 1995 as an independent body and works closely with UK Government to enforce the regulations.

Ecosystem service

Ecosystem services are the various benefits that humans derive from healthy ecosystems. These ecosystems, when functioning well, offer such things as provision of food, natural pollination of crops, clean air and water, decomposition of wastes, or flood control. Ecosystem services are grouped into four broad categories of services. There are provisioning services, such as the production of food and water. Regulating services, such as the control of climate and disease. Supporting services, such as nutrient cycles and oxygen production. And finally there are cultural services, such as spiritual and recreational benefits. Evaluations of ecosystem services may include assigning an economic value to them. For example, estuarine and coastal ecosystems are marine ecosystems that perform the four categories of ecosystem services in several ways. Firstly, their provisioning services include marine resources and genetic resources. Secondly, their supporting services include nutrient cycling and primary production. Thirdly, their regulating services include carbon sequestration (which helps with climate change mitigation) and flood control. Lastly, their cultural services include recreation and tourism. The Millennium Ecosystem Assessment (MA) in the early 2000s has made this concept better known. Definition Ecosystem services or eco-services are defined as the goods and services provided by ecosystems to humans. Per the 2006 Millennium Ecosystem Assessment (MA), ecosystem services are "the benefits people obtain from ecosystems". The MA also delineated the four categories of ecosystem services into provisioning, regulating, supporting, and cultural. By 2010, there had evolved various working definitions and descriptions of ecosystem services in the literature. To prevent double-counting in ecosystem services audits, for instance, The Economics of Ecosystems and Biodiversity (TEEB) replaced "Supporting Services" in the MA with "Habitat Services" and "ecosystem functions", defined as "a subset of the interactions between ecosystem structure and processes that underpin the capacity of an ecosystem to provide goods and services". While Gretchen Daily's original definition distinguished between ecosystem goods and ecosystem services, Robert Costanza and colleagues' later work and that of the Millennium Ecosystem Assessment lumped all of these together as ecosystem services. Categories Four different types of ecosystem services have been distinguished by the scientific body: regulating services, provisioning services, cultural services and supporting services. An ecosystem does not necessarily offer all four types of services simultaneously; but given the intricate nature of any ecosystem, it is usually assumed that humans benefit from a combination of these services. The services offered by diverse types of ecosystems (forests, seas, coral reefs, mangroves, etc.) differ in nature and in consequence. In fact, some services directly affect the livelihood of neighboring human populations (such as fresh water, food or aesthetic value, etc.) while other services affect general environmental conditions by which humans are indirectly impacted (such as climate change, erosion regulation or natural hazard regulation, etc.). The Millennium Ecosystem Assessment report 2005 defined ecosystem services as benefits people obtain from ecosystems and distinguishes four categories of ecosystem services, where the so-called supporting services are regarded as the basis for the services of the other three categories. Provisioning services Provisioning services consist of all "the products obtained from ecosystems". The following services are also known as ecosystem goods: food (including seafood and game), crops, wild foods, and spices raw materials (including lumber, skins, fuelwood, organic matter, fodder, and fertilizer) genetic resources (including crop improvement genes, and health care) biogenic minerals medicinal resources (including pharmaceuticals, chemical models, and test and assay organisms) energy (hydropower, biomass fuels) ornamental resources (including fashion, handicrafts, jewelry, pets, worship, decoration, and souvenirs like furs, feathers, ivory, orchids, butterflies, aquarium fish, shells, etc.) Forests and forest management produce a large type and variety of timber products, including roundwood, sawnwood, panels, and engineered wood, e.g., cross-laminated timber, as well as pulp and paper. Besides the production of timber, forestry activities may also result in products that undergo little processing, such as fire wood, charcoal, wood chips and roundwood used in an unprocessed form. Global production and trade of all major wood-based products recorded their highest ever values in 2018. Production, imports and exports of roundwood, sawnwood, wood-based panels, wood pulp, wood charcoal and pellets reached their maximum quantities since 1947 when FAO started reporting global forest product statistics. In 2018, growth in production of the main wood-based product groups ranged from 1 percent (woodbased panels) to 5 percent (industrial roundwood). The fastest growth occurred in the Asia-Pacific, Northern American and European regions, likely due to positive economic growth in these areas. Over 40% of the territory in the European Union is covered by forests. This region has grown via afforestation by roughly 0.4% year in recent decades. In the European Union, just 60% of the yearly forest growth is harvested. Forests also provide non-wood forest products, including fodder, aromatic and medicinal plants, and wild foods. Worldwide, around 1 billion people depend to some extent on wild foods such as wild meat, edible insects, edible plant products, mushrooms and fish, which often contain high levels of key micronutrients. The value of forest foods as a nutritional resource is not limited to low- and middle-income countries; more than 100 million people in the European Union (EU) regularly consume wild food. Some 2.4 billion people – in both urban and rural settings – use wood-based energy for cooking. Regulating services Regulating services are the "benefits obtained from the regulation of ecosystem processes". These include: Purification of water and air Carbon sequestration (this contributes to climate change mitigation) Waste decomposition and detoxification Predation regulates prey populations Biological control pest and disease control Pollination Disturbance regulation, i.e. flood protection Water purification An example for water purification as an ecosystem service is as follows: In New York City, where the quality of drinking water had fallen below standards required by the U.S. Environmental Protection Agency (EPA), authorities opted to restore the polluted Catskill Watershed that had previously provided the city with the ecosystem service of water purification. Once the input of sewage and pesticides to the watershed area was reduced, natural abiotic processes such as soil absorption and filtration of chemicals, together with biotic recycling via root systems and soil microorganisms, water quality improved to levels that met government standards. The cost of this investment in natural capital was estimated at $1–1.5 billion, which contrasted dramatically with the estimated $6–8 billion cost of constructing a water filtration plant plus the $300 million annual running costs. Pollination Pollination of crops by bees is required for 15–30% of U.S. food production; most large-scale farmers import non-native honey bees to provide this service. A 2005 study reported that in California's agricultural region, it was found that wild bees alone could provide partial or complete pollination services or enhance the services provided by honey bees through behavioral interactions. However, intensified agricultural practices can quickly erode pollination services through the loss of species. The remaining species are unable to compensate this. The results of this study also indicate that the proportion of chaparral and oak-woodland habitat available for wild bees within 1–2 km of a farm can stabilize and enhance the provision of pollination services. The presence of such ecosystem elements functions almost like an insurance policy for farmers. Buffer zones Coastal and estuarine ecosystems act as buffer zones against natural hazards and environmental disturbances, such as floods, cyclones, tidal surges and storms. The role they play is to "[absorb] a portion of the impact and thus [lessen] its effect on the land". Wetlands (which include saltwater swamps, salt marshes, ...) and the vegetation it supports – trees, root mats, etc. – retain large amounts of water (surface water, snowmelt, rain, groundwater) and then slowly releases them back, decreasing the likeliness of floods. Mangrove forests protect coastal shorelines from tidal erosion or erosion by currents; a process that was studied after the 1999 cyclone that hit India. Villages that were surrounded with mangrove forests encountered less damages than other villages that were not protected by mangroves. Supporting services Supporting services are the services that allow for the other ecosystem services to be present. They have indirect impacts on humans that last over a long period of time. Several services can be considered as being both supporting services and regulating/cultural/provisioning services. Supporting services include for example nutrient cycling, primary production, soil formation, habitat provision. These services make it possible for the ecosystems to continue providing services such as food supply, flood regulation, and water purification. Nutrient cycling Nutrient cycling is the movement of nutrients through an ecosystem by biotic and abiotic processes. The ocean is a vast storage pool for these nutrients, such as carbon, nitrogen and phosphorus. The nutrients are absorbed by the basic organisms of the marine food web and are thus transferred from one organism to the other and from one ecosystem to the other. Nutrients are recycled through the life cycle of organisms as they die and decompose, releasing the nutrients into the neighboring environment. "The service of nutrient cycling eventually impacts all other ecosystem services as all living things require a constant supply of nutrients to survive". Primary production Primary production refers to the production of organic matter, i.e., chemically bound energy, through processes such as photosynthesis and chemosynthesis. The organic matter produced by primary producers forms the basis of all food webs. Further, it generates oxygen (O2), a molecule necessary to sustain animals and humans. On average, a human consumes about 550 liter of oxygen per day, whereas plants produce 1,5 liter of oxygen per 10 grams of growth. Cultural services Cultural services relate to the non-material world, as they benefit the benefit recreational, aesthetic, cognitive and spiritual activities, which are not easily quantifiable in monetary terms. They include: cultural (including use of nature as motif in books, film, painting, folklore, national symbols, advertising, etc.) spiritual and historical (including use of nature for religious or heritage value or natural) recreational experiences (including ecotourism, outdoor sports, and recreation) science and education (including use of natural systems for school excursions, and scientific discovery) therapeutic (including eco-therapy, social forestry and animal assisted therapy) As of 2012, there was a discussion as to how the concept of cultural ecosystem services could be operationalized, how landscape aesthetics, cultural heritage, outdoor recreation, and spiritual significance to define can fit into the ecosystem services approach. who vote for models that explicitly link ecological structures and functions with cultural values and benefits. Likewise, there has been a fundamental critique of the concept of cultural ecosystem services that builds on three arguments: Pivotal cultural values attaching to the natural/cultivated environment rely on an area's unique character that cannot be addressed by methods that use universal scientific parameters to determine ecological structures and functions. If a natural/cultivated environment has symbolic meanings and cultural values the object of these values are not ecosystems but shaped phenomena like mountains, lakes, forests, and, mainly, symbolic landscapes. Cultural values do result not from properties produced by ecosystems but are the product of a specific way of seeing within the given cultural framework of symbolic experience. The Common International Classification of Ecosystem Services (CICES) is a classification scheme developed to accounting systems (like National counts etc.), in order to avoid double-counting of Supporting Services with others Provisioning and Regulating Services. Recreation and tourism Sea sports are very popular among coastal populations: surfing, snorkeling, whale watching, kayaking, recreational fishing ... a lot of tourists also travel to resorts close to the sea or rivers or lakes to be able to experience these activities, and relax near the water. The United Nations Sustainable Development Goal 14 also has targets aimed at enhancing the use of ecosystem services for sustainable tourism especially in Small Island Developing States. Estuarine and coastal ecosystem services Estuarine and marine coastal ecosystems are both marine ecosystems. Together, these ecosystems perform the four categories of ecosystem services in a variety of ways: The provisioning services include forest products, marine products, fresh water, raw materials, biochemical and genetic resources. Regulating services include carbon sequestration (contributing to climate change mitigation) as well as waste treatment and disease regulation and buffer zones. Supporting services of coastal ecosystems include nutrient cycling, biologically mediated habitats and primary production. Cultural services of coastal ecosystems include inspirational aspects, recreation and tourism, science and education. Coasts and their adjacent areas on and offshore are an important part of a local ecosystem. The mixture of fresh water and salt water (brackish water) in estuaries provides many nutrients for marine life. Salt marshes, mangroves and beaches also support a diversity of plants, animals and insects crucial to the food chain. The high level of biodiversity creates a high level of biological activity, which has attracted human activity for thousands of years. Coasts also create essential material for organisms to live by, including estuaries, wetland, seagrass, coral reefs, and mangroves. Coasts provide habitats for migratory birds, sea turtles, marine mammals, and coral reefs. Economics There are questions regarding the environmental and economic values of ecosystem services. Some people may be unaware of the environment in general and humanity's interrelatedness with the natural environment, which may cause misconceptions. Although environmental awareness is rapidly improving in our contemporary world, ecosystem capital and its flow are still poorly understood, threats continue to impose, and we suffer from the so-called 'tragedy of the commons'. Many efforts to inform decision-makers of current versus future costs and benefits now involve organizing and translating scientific knowledge to economics, which articulate the consequences of our choices in comparable units of impact on human well-being. An especially challenging aspect of this process is that interpreting ecological information collected from one spatial-temporal scale does not necessarily mean it can be applied at another; understanding the dynamics of ecological processes relative to ecosystem services is essential in aiding economic decisions. Weighting factors such as a service's irreplaceability or bundled services can also allocate economic value such that goal attainment becomes more efficient. The economic valuation of ecosystem services also involves social communication and information, areas that remain particularly challenging and are the focus of many researchers. In general, the idea is that although individuals make decisions for any variety of reasons, trends reveal the aggregated preferences of a society, from which the economic value of services can be inferred and assigned. The six major methods for valuing ecosystem services in monetary terms are: Avoided cost: Services allow society to avoid costs that would have been incurred in the absence of those services (e.g. waste treatment by wetland habitats avoids health costs) Replacement cost: Services could be replaced with human-made systems (e.g. restoration of the Catskill Watershed cost less than the construction of a water purification plant) Factor income: Services provide for the enhancement of incomes (e.g. improved water quality increases the commercial take of a fishery and improves the income of fishers) Travel cost: Service demand may require travel, whose costs can reflect the implied value of the service (e.g. value of ecotourism experience is at least what a visitor is willing to pay to get there) Hedonic pricing: Service demand may be reflected in the prices people will pay for associated goods (e.g. coastal housing prices exceed that of inland homes) Contingent valuation: Service demand may be elicited by posing hypothetical scenarios that involve some valuation of alternatives (e.g. visitors willing to pay for increased access to national parks) A peer-reviewed study published in 1997 estimated the value of the world's ecosystem services and natural capital to be between US$16 and $54 trillion per year, with an average of US$33 trillion per year. However, Salles (2011) indicated 'The total value of biodiversity is infinite, so having debate about what is the total value of nature is actually pointless because we can't live without it'. As of 2012, many companies were not fully aware of the extent of their dependence and impact on ecosystems and the possible ramifications. Likewise, environmental management systems and environmental due diligence tools are more suited to handle "traditional" issues of pollution and natural resource consumption. Most focus on environmental impacts, not dependence. Several tools and methodologies can help the private sector value and assess ecosystem services, including Our Ecosystem, the 2008 Corporate Ecosystem Services Review, the Artificial Intelligence for Environment & Sustainability (ARIES) project from 2007, the Natural Value Initiative (2012) and InVEST (Integrated Valuation of Ecosystem Services & Tradeoffs, 2012) To provide an example of a cost comparison: The land of the United States Department of Defense is said to provide substantial ecosystem services to local communities, including benefits to carbon storage, resiliency to climate, and endangered species habitat. As of 2020, the Eglin Air Force Base is said to provide about $110 million in ecosystem services per year, $40 million more than if no base was present. Payments Management and policy Although monetary pricing continues with respect to the valuation of ecosystem services, the challenges in policy implementation and management are significant and considerable. The administration of common pool resources has been a subject of extensive academic pursuit. From defining the problems to finding solutions that can be applied in practical and sustainable ways, there is much to overcome. Considering options must balance present and future human needs, and decision-makers must frequently work from valid but incomplete information. Existing legal policies are often considered insufficient since they typically pertain to human health-based standards that are mismatched with necessary means to protect ecosystem health and services. In 2000, to improve the information available, the implementation of an Ecosystem Services Framework has been suggested (ESF), which integrates the biophysical and socio-economic dimensions of protecting the environment and is designed to guide institutions through multidisciplinary information and jargon, helping to direct strategic choices. As of 2005 Local to regional collective management efforts were considered appropriate for services like crop pollination or resources like water. Another approach that has become increasingly popular during the 1990s is the marketing of ecosystem services protection. Payment and trading of services is an emerging worldwide small-scale solution where one can acquire credits for activities such as sponsoring the protection of carbon sequestration sources or the restoration of ecosystem service providers. In some cases, banks for handling such credits have been established and conservation companies have even gone public on stock exchanges, defining an evermore parallel link with economic endeavors and opportunities for tying into social perceptions. However, crucial for implementation are clearly defined land rights, which are often lacking in many developing countries. In particular, many forest-rich developing countries suffering deforestation experience conflict between different forest stakeholders. In addition, concerns for such global transactions include inconsistent compensation for services or resources sacrificed elsewhere and misconceived warrants for irresponsible use. As of 2001, another approach focused on protecting ecosystem service biodiversity hotspots. Recognition that the conservation of many ecosystem services aligns with more traditional conservation goals (i.e. biodiversity) has led to the suggested merging of objectives for maximizing their mutual success. This may be particularly strategic when employing networks that permit the flow of services across landscapes, and might also facilitate securing the financial means to protect services through a diversification of investors. For example, as of 2013, there had been interest in the valuation of ecosystem services provided by shellfish production and restoration. A keystone species, low in the food chain, bivalve shellfish such as oysters support a complex community of species by performing a number of functions essential to the diverse array of species that surround them. There is also increasing recognition that some shellfish species may impact or control many ecological processes; so much so that they are included on the list of "ecosystem engineers"—organisms that physically, biologically or chemically modify the environment around them in ways that influence the health of other organisms. Many of the ecological functions and processes performed or affected by shellfish contribute to human well-being by providing a stream of valuable ecosystem services over time by filtering out particulate materials and potentially mitigating water quality issues by controlling excess nutrients in the water. As of 2018, the concept of ecosystem services had not been properly implemented into international and regional legislation yet. Notwithstanding, the United Nations Sustainable Development Goal 15 has a target to ensure the conservation, restoration, and sustainable use of ecosystem services. An estimated $125 trillion to $140 trillion is added to the economy each year by all ecosystem services. However, many of these services are at risk due to climate and other anthropogenic impacts. Climate-driven shifts in biome ranges is expected to cause a 9% decline in ecosystem services on average at global scale by 2100 Ecosystem-based adaptation (EbA) Land use change decisions Ecosystem services decisions require making complex choices at the intersection of ecology, technology, society, and the economy. The process of making ecosystem services decisions must consider the interaction of many types of information, honor all stakeholder viewpoints, including regulatory agencies, proposal proponents, decision makers, residents, NGOs, and measure the impacts on all four parts of the intersection. These decisions are usually spatial, always multi-objective, and based on uncertain data, models, and estimates. Often it is the combination of the best science combined with the stakeholder values, estimates and opinions that drive the process. One analytical study modeled the stakeholders as agents to support water resource management decisions in the Middle Rio Grande basin of New Mexico. This study focused on modeling the stakeholder inputs across a spatial decision, but ignored uncertainty. Another study used Monte Carlo methods to exercise econometric models of landowner decisions in a study of the effects of land-use change. Here the stakeholder inputs were modeled as random effects to reflect the uncertainty. A third study used a Bayesian decision support system to both model the uncertainty in the scientific information Bayes Nets and to assist collecting and fusing the input from stakeholders. This study was about siting wave energy devices off the Oregon Coast, but presents a general method for managing uncertain spatial science and stakeholder information in a decision making environment. Remote sensing data and analyses can be used to assess the health and extent of land cover classes that provide ecosystem services, which aids in planning, management, monitoring of stakeholders' actions, and communication between stakeholders. In Baltic countries scientists, nature conservationists and local authorities are implementing integrated planning approach for grassland ecosystems. They are developing an integrated planning tool based on GIS (geographic information system) technology and put online that will help for planners to choose the best grassland management solution for concrete grassland. It will look holistically at the processes in the countryside and help to find best grassland management solutions by taking into account both natural and socioeconomic factors of the particular site. History While the notion of human dependence on Earth's ecosystems reaches to the start of Homo sapiens existence, the term 'natural capital' was first coined by E. F. Schumacher in 1973 in his book Small is Beautiful. Recognition of how ecosystems could provide complex services to humankind date back to at least Plato (c. 400 BC) who understood that deforestation could lead to soil erosion and the drying of springs. Modern ideas of ecosystem services probably began when Marsh challenged in 1864 the idea that Earth's natural resources are unbounded by pointing out changes in soil fertility in the Mediterranean. It was not until the late 1940s that three key authors—Henry Fairfield Osborn, Jr, William Vogt, and Aldo Leopold—promoted recognition of human dependence on the environment. In 1956, Paul Sears drew attention to the critical role of the ecosystem in processing wastes and recycling nutrients. In 1970, Paul Ehrlich and Rosa Weigert called attention to "ecological systems" in their environmental science textbook and "the most subtle and dangerous threat to man's existence ... the potential destruction, by man's own activities, of those ecological systems upon which the very existence of the human species depends". The term environmental services was introduced in a 1970 report of the Study of Critical Environmental Problems, which listed services including insect pollination, fisheries, climate regulation and flood control. In following years, variations of the term were used, but eventually 'ecosystem services' became the standard in scientific literature. The ecosystem services concept has continued to expand and includes socio-economic and conservation objectives.

Physical geography

Physical geography (also known as physiography) is one of the three main branches of geography. Physical geography is the branch of natural science which deals with the processes and patterns in the natural environment such as the atmosphere, hydrosphere, biosphere, and geosphere. This focus is in contrast with the branch of human geography, which focuses on the built environment, and technical geography, which focuses on using, studying, and creating tools to obtain, analyze, interpret, and understand spatial information. The three branches have significant overlap, however. Sub-branches Physical geography can be divided into several branches or related fields, as follows: Geomorphology is concerned with understanding the surface of the Earth and the processes by which it is shaped, both at the present as well as in the past. Geomorphology as a field has several sub-fields that deal with the specific landforms of various environments, e.g. desert geomorphology and fluvial geomorphology; however, these sub-fields are united by the core processes which cause them, mainly tectonic or climatic processes. Geomorphology seeks to understand landform history and dynamics, and predict future changes through a combination of field observation, physical experiment, and numerical modeling (Geomorphometry). Early studies in geomorphology are the foundation for pedology, one of two main branches of soil science. Hydrology is predominantly concerned with the amounts and quality of water moving and accumulating on the land surface and in the soils and rocks near the surface and is typified by the hydrological cycle. Thus the field encompasses water in rivers, lakes, aquifers and to an extent glaciers, in which the field examines the process and dynamics involved in these bodies of water. Hydrology has historically had an important connection with engineering and has thus developed a largely quantitative method in its research; however, it does have an earth science side that embraces the systems approach. Similar to most fields of physical geography it has sub-fields that examine the specific bodies of water or their interaction with other spheres e.g. limnology and ecohydrology. Glaciology is the study of glaciers and ice sheets, or more commonly the cryosphere or ice and phenomena that involve ice. Glaciology groups the latter (ice sheets) as continental glaciers and the former (glaciers) as alpine glaciers. Although research in the areas is similar to research undertaken into both the dynamics of ice sheets and glaciers, the former tends to be concerned with the interaction of ice sheets with the present climate and the latter with the impact of glaciers on the landscape. Glaciology also has a vast array of sub-fields examining the factors and processes involved in ice sheets and glaciers e.g. snow hydrology and glacial geology. Biogeography is the science which deals with geographic patterns of species distribution and the processes that result in these patterns. Biogeography emerged as a field of study as a result of the work of Alfred Russel Wallace, although the field prior to the late twentieth century had largely been viewed as historic in its outlook and descriptive in its approach. The main stimulus for the field since its founding has been that of evolution, plate tectonics and the theory of island biogeography. The field can largely be divided into five sub-fields: island biogeography, paleobiogeography, phylogeography, zoogeography and phytogeography. Climatology is the study of the climate, scientifically defined as weather conditions averaged over a long period of time. Climatology examines both the nature of micro (local) and macro (global) climates and the natural and anthropogenic influences on them. The field is also sub-divided largely into the climates of various regions and the study of specific phenomena or time periods e.g. tropical cyclone rainfall climatology and paleoclimatology. Soil geography deals with the distribution of soils across the terrain. This discipline, between geography and soil science, is fundamental to both physical geography and pedology. Pedology is the study of soils in their natural environment. It deals with pedogenesis, soil morphology, soil classification. Soil geography studies the spatial distribution of soils as it relates to topography, climate (water, air, temperature), soil life (micro-organisms, plants, animals) and mineral materials within soils (biogeochemical cycles). Palaeogeography is a cross-disciplinary study that examines the preserved material in the stratigraphic record to determine the distribution of the continents through geologic time. Almost all the evidence for the positions of the continents comes from geology in the form of fossils or paleomagnetism. The use of these data has resulted in evidence for continental drift, plate tectonics, and supercontinents. This, in turn, has supported palaeogeographic theories such as the Wilson cycle. Coastal geography is the study of the dynamic interface between the ocean and the land, incorporating both the physical geography (i.e. coastal geomorphology, geology, and oceanography) and the human geography of the coast. It involves an understanding of coastal weathering processes, particularly wave action, sediment movement and weathering, and also the ways in which humans interact with the coast. Coastal geography, although predominantly geomorphological in its research, is not just concerned with coastal landforms, but also the causes and influences of sea level change. Oceanography is the branch of physical geography that studies the Earth's oceans and seas. It covers a wide range of topics, including marine organisms and ecosystem dynamics (biological oceanography); ocean currents, waves, and geophysical fluid dynamics (physical oceanography); plate tectonics and the geology of the sea floor (geological oceanography); and fluxes of various chemical substances and physical properties within the ocean and across its boundaries (chemical oceanography). These diverse topics reflect multiple disciplines that oceanographers blend to further knowledge of the world ocean and understanding of processes within it. Quaternary science is an interdisciplinary field of study focusing on the Quaternary period, which encompasses the last 2.6 million years. The field studies the last ice age and the recent interstadial the Holocene and uses proxy evidence to reconstruct the past environments during this period to infer the climatic and environmental changes that have occurred. Landscape ecology is a sub-discipline of ecology and geography that address how spatial variation in the landscape affects ecological processes such as the distribution and flow of energy, materials, and individuals in the environment (which, in turn, may influence the distribution of landscape "elements" themselves such as hedgerows). The field was largely funded by the German geographer Carl Troll. Landscape ecology typically deals with problems in an applied and holistic context. The main difference between biogeography and landscape ecology is that the latter is concerned with how flows or energy and material are changed and their impacts on the landscape whereas the former is concerned with the spatial patterns of species and chemical cycles. Geomatics is the field of gathering, storing, processing, and delivering geographic information, or spatially referenced information. Geomatics includes geodesy (scientific discipline that deals with the measurement and representation of the earth, its gravitational field, and other geodynamic phenomena, such as crustal motion, oceanic tides, and polar motion), cartography, geographical information science (GIS) and remote sensing (the short or large-scale acquisition of information of an object or phenomenon, by the use of either recording or real-time sensing devices that are not in physical or intimate contact with the object). Environmental geography is a branch of geography that analyzes the spatial aspects of interactions between humans and the natural world. The branch bridges the divide between human and physical geography and thus requires an understanding of the dynamics of geology, meteorology, hydrology, biogeography, and geomorphology, as well as the ways in which human societies conceptualize the environment. Although the branch was previously more visible in research than at present with theories such as environmental determinism linking society with the environment. It has largely become the domain of the study of environmental management or anthropogenic influences. Journals and literature Main category: Geography Journals Mental geography and earth science journals communicate and document the results of research carried out in universities and various other research institutions. Most journals cover a specific publish the research within that field, however unlike human geographers, physical geographers tend to publish in inter-disciplinary journals rather than predominantly geography journal; the research is normally expressed in the form of a scientific paper. Additionally, textbooks, books, and communicate research to laypeople, although these tend to focus on environmental issues or cultural dilemmas. Examples of journals that publish articles from physical geographers are: Historical evolution of the discipline From the birth of geography as a science during the Greek classical period and until the late nineteenth century with the birth of anthropogeography (human geography), geography was almost exclusively a natural science: the study of location and descriptive gazetteer of all places of the known world. Several works among the best known during this long period could be cited as an example, from Strabo (Geography), Eratosthenes (Geographika) or Dionysius Periegetes (Periegesis Oiceumene) in the Ancient Age. In more modern times, these works include the Alexander von Humboldt (Kosmos) in the nineteenth century, in which geography is regarded as a physical and natural science through the work Summa de Geografía of Martín Fernández de Enciso from the early sixteenth century, which indicated for the first time the New World. During the eighteenth and nineteenth centuries, a controversy exported from geology, between supporters of James Hutton (uniformitarianism thesis) and Georges Cuvier (catastrophism) strongly influenced the field of geography, because geography at this time was a natural science. Two historical events during the nineteenth century had a great effect on the further development of physical geography. The first was the European colonial expansion in Asia, Africa, Australia and even America in search of raw materials required by industries during the Industrial Revolution. This fostered the creation of geography departments in the universities of the colonial powers and the birth and development of national geographical societies, thus giving rise to the process identified by Horacio Capel as the institutionalization of geography. The exploration of Siberia is an example. In the mid-eighteenth century, many geographers were sent to perform geographical surveys in the area of Arctic Siberia. Among these is who is considered the patriarch of Russian geography, Mikhail Lomonosov. In the mid-1750s Lomonosov began working in the Department of Geography, Academy of Sciences to conduct research in Siberia. They showed the organic origin of soil and developed a comprehensive law on the movement of the ice, thereby founding a new branch of geography: glaciology. In 1755 on his initiative was founded Moscow University where he promoted the study of geography and the training of geographers. In 1758 he was appointed director of the Department of Geography, Academy of Sciences, a post from which would develop a working methodology for geographical survey guided by the most important long expeditions and geographical studies in Russia. The contributions of the Russian school became more frequent through his disciples, and in the nineteenth century we have great geographers such as Vasily Dokuchaev who performed works of great importance as a "principle of comprehensive analysis of the territory" and "Russian Chernozem". In the latter, he introduced the geographical concept of soil, as distinct from a simple geological stratum, and thus found a new geographic area of study: pedology. Climatology also received a strong boost from the Russian school by Wladimir Köppen whose main contribution, climate classification, is still valid today. However, this great geographer also contributed to the paleogeography through his work "The climates of the geological past" which is considered the father of paleoclimatology. Russian geographers who made great contributions to the discipline in this period were: NM Sibirtsev, Pyotr Semyonov, K.D. Glinka, Neustrayev, among others. The second important process is the theory of evolution by Darwin in mid-century (which decisively influenced the work of Friedrich Ratzel, who had academic training as a zoologist and was a follower of Darwin's ideas) which meant an important impetus in the development of Biogeography. Another major event in the late nineteenth and early twentieth centuries took place in the United States. William Morris Davis not only made important contributions to the establishment of discipline in his country but revolutionized the field to develop cycle of erosion theory which he proposed as a paradigm for geography in general, although in actually served as a paradigm for physical geography. His theory explained that mountains and other landforms are shaped by factors that are manifested cyclically. He explained that the cycle begins with the lifting of the relief by geological processes (faults, volcanism, tectonic upheaval, etc.). Factors such as rivers and runoff begin to create V-shaped valleys between the mountains (the stage called "youth"). During this first stage, the terrain is steeper and more irregular. Over time, the currents can carve wider valleys ("maturity") and then start to wind, towering hills only ("senescence"). Finally, everything comes to what is a plain flat plain at the lowest elevation possible (called "baseline") This plain was called by Davis' "peneplain" meaning "almost plain" Then river rejuvenation occurs and there is another mountain lift and the cycle continues. Although Davis's theory is not entirely accurate, it was absolutely revolutionary and unique in its time and helped to modernize and create a geography subfield of geomorphology. Its implications prompted a myriad of research in various branches of physical geography. In the case of the Paleogeography, this theory provided a model for understanding the evolution of the landscape. For hydrology, glaciology, and climatology as a boost investigated as studying geographic factors shape the landscape and affect the cycle. The bulk of the work of William Morris Davis led to the development of a new branch of physical geography: Geomorphology whose contents until then did not differ from the rest of geography. Shortly after this branch would present a major development. Some of his disciples made significant contributions to various branches of physical geography such as Curtis Marbut and his invaluable legacy for Pedology, Mark Jefferson, Isaiah Bowman, among others.

Social environment

The social environment, social context, sociocultural context or milieu refers to the immediate physical and social setting in which people live or in which something happens or develops. It includes the culture that the individual was educated or lives in, and the people and institutions with whom they interact. The interaction may be in person or through communication media, even anonymous or one-way, and may not imply equality of social status. The social environment is a broader concept than that of social class or social circle. The physical and social environment is a determining factor in active and healthy aging in place, being a central factor in the study of environmental gerontology. Moreover, the social environment is the setting where people live and interact. It includes the buildings and roads around them, the jobs available, and how money flows; relationships between people, like who has power and how different groups get along; and culture, like art, religion, and traditions. It includes the physical world and the way people relate to each other and their communities. Components The physical environment is the ever-changing natural world, including weather, land, and natural resources. Floods or earthquakes can alter the landscape, affecting how plants and animals live. Human interaction with nature can also have an impact. For example, logging can change the weather in that area, pollution can make water dirty, and habitat fragmentation caused by human activity makes it so animals cannot move around as easily, which can cause problems for their families. Social relations are how people interact with each other. Sociologist Emile Durkheim thought that if these interactions were disrupted, it could affect how we feel. Social relations can offer social support, which means the different ways people help each other out. This could be emotional support, like comforting someone when they are sad, or practical support, like helping with chores. Being part of groups, like families or clubs, can also make people feel good about ourselves; conversely, not having good relationships or having too many problems with others can make them feel bad. So, having good connections with people can make us happier and healthier. "Sociocultural" basically means the mix of society and culture that affects how people think, feel, and act, which can also affect our health. It includes things like how wealth, education, career, cultural background, race, ethnicity, language, and beliefs shape people's identity and health. Interpersonal relationships are how people connect with others emotionally and socially. When someone has a mental disorder, it often affects how they get along with people. Sometimes, the disorder itself can cause conflicts with others. These conflicts can appear in different areas of our relationships. Family relationships are important because having a supportive family makes life easier. They're there for you no matter what, whether things are going great or not so great. When life gets tough, hearing comforting words from your mom, spouse, or siblings can help you feel better and give you the courage to face challenges. In this post, we're going to talk about why family is important, what makes a good family, and how to make your relationships with family members stronger. Social relationships are the connections between people like family, friends, neighbors, and coworkers. When scientists study how relationships affect human health and behavior, they usually focus on these close connections, not just formal ones like with doctors or lawyers. They are interested in how people interact with their social circle and how it impacts them overall. Work relationship: Work friendships are special connections between people at work. They are important because they affect the people involved and the company they work for. Friendships at work play a big role in how well someone does their job and how motivated they are. These relationships can be complicated, happening both at work and outside of it, and they can be good or bad. Not having any work friends can make someone feel really lonely and left out. Religious relationship: Religion can have a significant impact on relationships. Couples who share the same religious beliefs can find comfort and support in their faith. For example, they might pray together when they are arguing, which can help them deal with their feelings. Studies have shown that couples who pray together tend to focus more on what they have in common rather than their own individual worries. Having a strong religious foundation can also help couples get through difficult situations, like cheating. They might feel like their relationship is special because they believe it is part of God's plan for them. Overall, when couples share the same religious beliefs, it can make it easier for them to talk about their faith and support each other in their relationship. A sexual relationship, also called an intimate relationship, is when two people have a close bond either physically or emotionally. Intimacy usually means being close in a special way, and while it often involves sex, it can also happen in relationships without any sexual attraction, like between friends or family members. Importance of positive social environments and relationships for parents Where a child grows up and goes to school has a big impact on who they become friends with and how good those friendships are. Most of the time, kids make friends with people in their family or neighborhood. So, where parents choose to live, work, and send their kids to school can affect how healthy and happy their children are. Solidarity People with the same social environment often develop a sense of social solidarity; people often tend to trust and help one another, and to congregate in social groups. They will often think in similar styles and patterns, even though the conclusions which they reach may differ. Natural/artificial environment In order to enrich their lives, people have used natural resources, and in the process have brought about many changes in the natural environment. Human settlements, roads, farmlands, dams, and many other elements have all developed through the process. All these man-made components are included in human cultural environment, Erving Goffman in particular emphasising the deeply social nature of the individual environment. There are still many people living in villages and this is their social environment. A village is a township with production, living, ecology and culture. The state is trying to solve the problem of integrated rural development, which includes construction, expansion, and road building. Milieu/social structure C. Wright Mills contrasted the immediate milieu of jobs/family/neighborhood with the wider formations of the social structure, highlighting in particular a distinction between "the personal troubles of milieu" and the "public crises of social structure". Emile Durkheim took a wider view of the social environment (milieu social), arguing that it contained internalized expectations and representations of social forces/social facts: "Our whole social environment seems to be filled with forces which really exist only in our own minds" – collective representations. Phenomenology Phenomenologists contrast two alternative visions of society, as a deterministic constraint (milieu) and as a nurturing shell (ambiance). Max Scheler distinguishes between milieu as an experienced value-world, and the objective social environment on which we draw to create the former, noting that the social environment can either foster or restrain our creation of a personal milieu. Social surgery Pierre Janet saw neurosis in part as the product of the identified patient's social environment – family, social network, work etc. – and considered that in some instances what he termed "social surgery" to create a healthier environment could be a beneficial measure. Similar ideas have since been taken up in community psychiatry and family therapy.

Forest ecology

Forest ecology is the scientific study of the interrelated patterns, processes, flora, fauna, funga, and ecosystems in forests. The management of forests is known as forestry, silviculture, and forest management. A forest ecosystem is a natural woodland unit consisting of all plants, animals, and micro-organisms (biotic components) in that area functioning together with all of the non-living physical (abiotic) factors of the environment. Importance Forests have an enormously important role to play in the global ecosystem. Forests produce approximately 28% of the Earth's oxygen (the vast majority being created by oceanic plankton), they also serve as homes for millions of people, and billions depend on forests in some way. Likewise, a large proportion of the world's animal species live in forests. Forests are also used for economic purposes such as fuel and wood products. Forest ecology therefore has a great impact upon the whole biosphere and human activities that are sustained by it. Approaches Forests are studied at a number of organisational levels, from the individual organism to the ecosystem. However, as the term forest connotes an area inhabited by more than one organism, forest ecology most often concentrates on the level of the population, community or ecosystem. Logically, trees are an important component of forest research, but the wide variety of other life forms and abiotic components in most forests means that other elements, such as wildlife or soil nutrients, are also crucial components. Forest ecology shares characteristics and methodological approaches with other areas of terrestrial plant ecology, however, the presence of trees makes forest ecosystems and their study unique in numerous ways due to the potential for a wide variety of forest structures created by the uniquely large size and height of trees compared with other terrestrial plants. Forest pathology Community diversity and complexity Since trees can grow larger than other plant life-forms, there is the potential for a wide variety of forest structures (or physiognomies). The infinite number of possible spatial arrangements of trees of varying size and species makes for a highly intricate and diverse micro-environment in which environmental variables such as solar radiation, temperature, relative humidity, and wind speed can vary considerably over large and small distances. In addition, an important proportion of a forest ecosystem's biomass is often underground, where soil structure, water quality and quantity, and levels of various soil nutrients can vary greatly. Thus, forests are often highly heterogeneous environments compared to other terrestrial plant communities. This heterogeneity in turn can enable great biodiversity of species of both plants and animals. Some structures, such as tree ferns may be keystone species for a diverse range of other species. A number of factors within the forest affect biodiversity; primary factors enhancing wildlife abundance and biodiversity was the presence of diverse tree species within the forest and the absence of even aged timber management. For example, the wild turkey thrives when uneven heights and canopy variations exist and its numbers are diminished by even aged timber management. Forest management techniques that mimic natural disturbance events (variable retention forestry) can allow community diversity to recover rapidly for a variety of groups including beetles. Types of Forests Ecosystems Temperate Forests Tropical Forests Tropical forests are some of the most diverse ecosystems in the world. Although there are many different tree species present per acre of forest, many share similar appearances due to the similar environmental pressures. Some of these shared traits, possessed by many tropical trees, include thick and leathery leaves that are elongated and ovular with mid-ribs and drip-tips. These adaptations help to quickly drain water from the leaves, likely to help prevent algae or lichen growth and prevent water reflecting the sunlight or restricting transpiration. Commonly, tropical trees have large buttress roots on larger trees, and stilt roots on mid-sized trees which help support their tall and vertical structures in the shallow and moist soil. Tropical forests grow very densely due to the heavy rainfall and year-round growing season. This creates competition for light which causes many trees to grow very tall, blocking out most or all of the light from reaching the forest floor. Because of this, the canopy exhibits distinct stratified layers from the tallest trees to the tightly packed midstory trees below. Due to low light on the forest floor, there is a diverse population of epiphytes, a type of plant that grows on the canopy trees, rather than soil, to access better light. Many vines use a similar tactic, however they root in the ground, growing up the trees to reach light. The fauna in tropical forests also show many unique adaptations to fill various niches. These adaptations are possessed by different species depending on where they are located. For example, there are similar looking animals in the rainforests of South America and Africa that share ecological niches, however the mammals from South America are rodents while the African ones are ungulates. This clearly demonstrates the convergent evolution between species found in tropical forest environments. Coniferous Forests Conifers have unique traits that make them especially adapted to harsh conditions, including cold, drought, wind, and snow. Their leaves have a wax coating and are filled with resin to help prevent moisture loss, this makes them unpalatable to animals and slow to decompose. This leaf litter creates an acidic forest floor that is distinct to coniferous forests. Because of the types of leaves possessed by conifers, they face the problem of soil nutrient loss; this problem is solved through mycorrhizal symbiosis with fungi that help transport the limited nutrients to the trees in exchange for sugars. Some conifers are incapable of surviving without mycorrhizal fungi. The majority of conifers are also evergreen, allowing them to take advantage of the short growing seasons of their respective environments. Their thin tapered structure helps them to withstand strong winds without being blown over. The stereotypically cone shape of conifers helps prevent large quantities of snow from building up on their branches and breaking them. Due to the harsh environments that coniferous forests are commonly found, the diversity is limited in both plant and animal species. The colder climates limit the number of reptilian and amphibian species that can survive. The species more commonly found in coniferous forests are mammals, including large herbivores such as moose and elk, predators like bears and wolves, along with a few smaller species like rabbits, foxes, and mink. There are also a variety of migratory bird species and some birds of prey such as owls and hawks. Coniferous forests contain a variety of valuable pulp and lumber trees making them some of the most economically important ecosystems. They have also been historically sought for the fur trade due to the animals species that inhabit them. Island Forests Ecological Interactions Plant-Plant Interactions In forests, trees and shrubs often serve as nurse plants that facilitate the establishment and seedling growth of understory plants. The forest canopy protects young understory plants from extremes of temperature and dry conditions. Mycorrhizal Symbiosis An important interaction in forest ecosystems is the mycorrhizal network, which consists of fungi and plants that share symbiotic relationships. Mycorrhizal networks have been shown to increase the uptake of important nutrients, especially ones which disperse slowly into the soil like phosphorus. The fine hypha of the mycelium is able to reach farther into the soil than the roots of the plant, allowing it to better access phosphorus and water. The mycorrhizal network can also transport water and nutrients between plants. These interactions can help provide drought resistance to their symbiotic plants, helping protect them through the progression of climate change. However, it's been shown that the benefit of mycorrhizal networks vary greatly depending on the species of plant and nutrient availability. The plants’ benefit from mycorrhizal fungus decreases as nutrient density increases, because the plants' loss of sugars costs more than the benefit they receive. While many plants rely on mycorrhizal symbiosis, not all possess this ability, and those without are shown to be negatively affected by the presence of mycorrhizal fungi. Ecological potential of forest species The ecological potential of a particular species is a measure of its capacity to effectively compete in a given geographical area, ahead of other species, as they all try to occupy a natural space. For some areas it has been quantified, as for instance by Hans-Jürgen Otto, for central Europe. He takes three groups of parameters: Related to site requirements: Tolerance to low temperatures, tolerance to dry climate, frugality. Specific qualities: Shade tolerance, height growth, stability, longevity, regeneration capacity. Specific risks: Resistance to late freezing, resistance to wind/ice storm, resistance to fire, resistance to biotic agents. Every parameter is scored between 0 and 5 for each considered species, and then a global mean value calculated. A value above 3.5 is considered high, below 3.0 low, and intermediate for those in between. In this study Fagus sylvatica has a score of 3.82, Fraxinus excelsior 3.08 and Juglans regia 2.92; and are examples of the three categories. Matter and energy flows Energy flux Forests accumulate large amounts of standing biomass, and many are capable of accumulating it at high rates, i.e. they are highly productive. Such high levels of biomass and tall vertical structures represent large stores of potential energy that can be converted to kinetic energy under the right circumstances. The world’s forests contain about 606 gigatonnes of living biomass (above- and below-ground) and 59 gigatonnes of dead wood. Two such conversions of great importance are fires and treefalls, both of which radically alter the biota and the physical environment where they occur. Also, in forests of high productivity, the rapid growth of the trees themselves induces biotic and environmental changes, although at a slower rate and lower intensity than relatively instantaneous disturbances such as fires. Water Forest trees store large amounts of water because of their large size and anatomical/physiological characteristics. They are therefore important regulators of hydrological processes, especially those involving groundwater hydrology and local evaporation and rainfall/snowfall patterns. An estimated 399 million ha of forest is designated primarily for the protection of soil and water, an increase of 119 million ha since 1990. Thus, forest ecological studies are sometimes closely aligned with meteorological and hydrological studies in regional ecosystem or resource planning studies. Perhaps more importantly the duff or leaf litter can form a major repository of water storage. When this litter is removed or compacted (through grazing or human overuse), erosion and flooding are exacerbated as well as deprivation of dry season water for forest organisms. Death and regeneration Woody material, often referred to as coarse woody debris, decays relatively slowly in many forests in comparison to most other organic materials, due to a combination of environmental factors and wood chemistry (see lignin). Trees growing in arid and/or cold environments do so especially slowly. Thus, tree trunks and branches can remain on the forest floor for long periods, affecting such things as wildlife habitat, fire behaviour, and tree regeneration processes. Some trees leave behind eerie skeletons after death. In reality these deaths are actually very few compared to the amount of tree deaths that go unnoticed. Thousands of seedlings can be produced from a single tree but only a few can actually grow to maturity. Most of those deaths are caused from competition for light, water, or soil nutrients, this is called natural thinning. Singular deaths caused by natural thinning go unnoticed, but many deaths can help form forest ecosystems. There are four stages to forest regrowth after a disturbance, the establishment phase which is rapid increase in seedlings, the thinning phase which happens after a canopy is formed and the seedlings covered by it die, the transition phase which occurs when one tree from the canopy dies and creates a pocket of light giving new seedlings opportunity to grow, and lastly the steady-state phase which happens when the forest has different sizes and ages of trees.

Biological process

Biological processes are those processes that are necessary for an organism to live and that shape its capacities for interacting with its environment. Biological processes are made of many chemical reactions or other events that are involved in the persistence and transformation of life forms. Regulation of biological processes occurs when any process is modulated in its frequency, rate or extent. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. Homeostasis: regulation of the internal environment to maintain a constant state; for example, sweating to reduce temperature Organization: being structurally composed of one or more cells – the basic units of life Metabolism: transformation of energy by converting chemicals and energy into cellular components (anabolism) and decomposing organic matter (catabolism). Living things require energy to maintain internal organization (homeostasis) and to produce the other phenomena associated with life. Growth: maintenance of a higher rate of anabolism than catabolism. A growing organism increases in size in all of its parts, rather than simply accumulating matter. Response to stimuli: a response can take many forms, from the contraction of a unicellular organism to external chemicals, to complex reactions involving all the senses of multicellular organisms. A response is often expressed by motion; for example, the leaves of a plant turning toward the sun (phototropism), and chemotaxis. Interaction between organisms. the processes by which an organism has an observable effect on another organism of the same or different species. Also: cellular differentiation, fermentation, fertilisation, germination, tropism, hybridisation, metamorphosis, morphogenesis, photosynthesis, transpiration.

Sustainable Development Goals

The 2030 Agenda for Sustainable Development, adopted by all United Nations members in 2015, created 17 world Sustainable Development Goals (SDGs). The aim of these global goals is "peace and prosperity for people and the planet" – while tackling climate change and working to preserve oceans and forests. The SDGs highlight the connections between the environmental, social and economic aspects of sustainable development. Sustainability is at the center of the SDGs, as the term sustainable development implies. The short titles of the 17 SDGs are: No poverty (SDG 1), Zero hunger (SDG 2), Good health and well-being (SDG 3), Quality education (SDG 4), Gender equality (SDG 5), Clean water and sanitation (SDG 6), Affordable and clean energy (SDG 7), Decent work and economic growth (SDG 8), Industry, innovation and infrastructure (SDG 9), Reduced inequalities (SDG 10), Sustainable cities and communities (SDG 11), Responsible consumption and production (SDG 12), Climate action (SDG 13), Life below water (SDG 14), Life on land (SDG 15), Peace, justice, and strong institutions (SDG 16), and Partnerships for the goals (SDG 17). These goals are ambitious, and the reports and outcomes to date indicate a challenging path. Most, if not all, of the goals are unlikely to be met by 2030. Rising inequalities, climate change, and biodiversity loss are topics of concerns threatening progress. The COVID-19 pandemic in 2020 to 2023 made these challenges worse. The pandemic impacted all 17 goals and emphasized the interconnectedness of global health, economic, social, and environmental challenges. Some regions, such as Asia, have experienced significant setbacks during that time. The global effort for the SDGs calls for prioritizing environmental sustainability, understanding the indivisible nature of the goals, and seeking synergies across sectors. With regards to the political impact of the SDGs, it has been observed that they have mainly influenced global and national debates. By doing so, they have led to discursive effects for global and national debates. However, they have struggled to achieve transformative changes in policy and institutional structures. The uneven prioritization of goals reflects longstanding national development policies. This complicates the global endeavor towards sustainable development. For example, there has long been a tendency to favor socio-economic objectives over environmental ones. Funding remains a critical issue for achieving the SDGs. Significant financial resources would be required worldwide. The UN, other international organizations, and national governments are trying to assist with funding efforts. Furthermore, the role of private investment and a shift towards sustainable financing are also essential for realizing the SDGs. Examples of progress from some countries demonstrate that achieving sustainable development through concerted global action is possible. General description The SDGs are, in essence, universal, time-bound, and legally non-binding policy objectives agreed upon by governments. They come close to prescriptive international norms but are generally more specific, and they can be highly ambitious. The overarching UN program "2030 Agenda" presented the SDGs in 2015 as a "supremely ambitious and transformative vision" that should be accompanied by "bold and transformative steps" with "scale and ambition". Scholars noted that the goals had the potential to form overarching and crosscutting norms that integrate social and environmental considerations into new definitions of development. The SDGs are "unique and special, at least in five dimensions". Firstly, the apply to all countries of the world, not just developing countries like the Millennium Development Goals (from the year 2000 to 2015) did. Secondly, they target all three dimensions of sustainability and sustainable development, namely the environmental, economic and social dimension. Thirdly, the development and negotiations of the SDGs were not "town down" by civil servants but were relatively open and transparent, aiming to include "bottom up" participation. Fourthly, the SDGs have been "institutionally embedded at a higher political level than earlier goals in development policy": A new forum, the High-level Political Forum on Sustainable Development was created in 2013 to review the progress of the implementation of the SDGs. The fifth aspect about the SDGs that is unique is that they are "more visible in public discourse and more central in the United Nations system than earlier initiatives". Structure of goals and targets The lists of targets and indicators for each of the 17 SDGs was published in a UN resolution in July 2017. Each goal typically has eight to 12 targets, and each target has between one and four indicators used to measure progress toward reaching the targets, with the average of 1.5 indicators per target. The targets are either outcome targets (circumstances to be attained) or means of implementation targets. The latter targets were introduced late in the process of negotiating the SDGs to address the concern of some Member States about how the SDGs were to be achieved. Goal 17 is wholly about how the SDGs will be achieved. The numbering system of targets is as follows: Outcome targets use numbers, whereas means of implementation targets use lower case letters. For example, SDG 6 has a total of 8 targets. The first six are outcome targets and are labeled Targets 6.1 to 6.6. The final two targets are means of implementation targets and are labeled as Targets 6.a and 6.b. Indicators The United Nations Statistics Division (UNSD) website provides a current official indicator list which includes all updates until the 51st session Statistical Commission in March 2020. The indicators for the targets have varying levels of methodological development and availability of data at the global level. Initially, some indicators (called Tier 3 indicators) had no internationally established methodology or standards. Later, the global indicator framework was adjusted so that Tier 3 indicators were either abandoned, replaced or refined. As of 17 July 2020, there were 231 unique indicators. Data or information must address all vulnerable groups such as children, elderly people, persons with disabilities, refugees, indigenous peoples, migrants, and internally-displaced persons. For each indicator, the Inter-Agency and Expert Group tried to designate at least one custodian agency and focal point that would be responsible for developing the methodology, data collection, data aggregation, and later reporting. The division of indicators was primarily based on existing mandates and organizational capacity. For example, the World Bank established itself as a data gatekeeper in this process through its broad mandate, staff, budget, and expertise in large-scale data collection. The bank became formally involved in about 20 percent of all 231 SDG indicators; it served as the custodian agency for 20 of them and was involved in the development and monitoring of another 22. The indicator framework was comprehensively reviewed at the 51st session of the United Nations Statistical Commission in 2020. It will be reviewed again in 2025. At the 51st session of the Statistical Commission (held in New York City from 3 to 6 March 2020) a total of 36 changes to the global indicator framework were proposed for the commission's consideration. Some indicators were replaced, revised or deleted. Between 15 October 2018 and 17 April 2020, other changes were made to the indicators. Yet their measurement continues to be fraught with difficulties. Details of 17 goals and targets Goal 1: No Poverty SDG 1 is to: "End poverty in all its forms everywhere." Achieving SDG 1 would end extreme poverty globally by 2030. One of its indicators is the proportion of population living below the poverty line. The data gets analyzed by sex, age, employment status, and geographical location (urban/rural). Goal 2: Zero hunger (No hunger) SDG 2 is to: "End hunger, achieve food security and improved nutrition, and promote sustainable agriculture." Indicators for this goal are for example the prevalence of diet, prevalence of severe food insecurity, and prevalence of stunting among children under five years of age. Goal 3: Good health and well-being SDG 3 is to: "Ensure healthy lives and promote well-being for all at all ages." Important indicators here are life expectancy as well as child and maternal mortality. Further indicators are for example deaths from road traffic injuries, prevalence of current tobacco use, and suicide mortality rate. Goal 4: Quality education SDG 4 is to: "Ensure inclusive and equitable quality education and promote lifelong learning opportunities for all." The indicators for this goal are, for example, attendance rates at primary schools, completion rates of primary school education, participation in tertiary education, and so forth. In each case, parity indices are looked at to ensure that disadvantaged students do not miss out (data is collected on "female/male, rural/urban, bottom/top wealth quintile and others such as disability status, indigenous peoples") . There is also an indicator around the facilities that the school buildings have (access to electricity, the internet, computers, drinking water, toilets etc.). Goal 5: Gender equality SDG 5 is to: "Achieve gender equality and empower all women and girls." Indicators include, for example, having suitable legal frameworks and the representation by women in national parliament or in local deliberative bodies. Numbers on forced marriage and female genital mutilation/cutting (FGM/C) are also included in another indicator. Goal 6: Clean water and sanitation SDG 6 is to: "Ensure availability and sustainable management of water and sanitation for all." The Joint Monitoring Programme (JMP) of WHO and UNICEF is responsible for monitoring progress to achieve the first two targets of this goal. Important indicators for this goal are the percentages of the population that uses safely managed drinking water, and has access to safely managed sanitation. The JMP reported in 2017 that 4.5 billion people do not have safely managed sanitation. Another indicator looks at the proportion of domestic and industrial wastewater that is safely treated. Goal 7: Affordable and clean energy SDG 7 is to "Ensure access to affordable, reliable, sustainable and modern energy for all." One of the indicators for this goal is the percentage of population with access to electricity (progress in expanding access to electricity has been made in several countries, notably India, Bangladesh, and Kenya). Other indicators look at the renewable energy share and energy efficiency. Goal 8: Decent work and economic growth SDG 8 is to: "Promote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all." Important indicators for this goal include economic growth in least developed countries and the rate of real GDP per capita. Further examples are rates of youth unemployment and occupational injuries or the number of women engaged in the labor force compared to men. Goal 9: Industry, Innovation and Infrastructure SDG 9 is to: "Build resilient infrastructure, promote inclusive and sustainable industrialization, and foster innovation." Indicators in this goal include for example, the proportion of people who are employed in manufacturing activities, are living in areas covered by a mobile network, or who have access to the internet. An indicator that is connected to climate change is "CO2 emissions per unit of value added." Goal 10: Reduced inequality SDG 10 is to: "Reduce inequality within and among countries." Important indicators for this SDG are: income disparities, aspects of gender and disability, as well as policies for migration and mobility of people. Goal 11: Sustainable cities and communities SDG 11 is to: "Make cities and human settlements inclusive, safe, resilient, and sustainable." Important indicators for this goal are the number of people living in urban slums, the proportion of the urban population who has convenient access to public transport, and the extent of built-up area per person. Goal 12: Responsible consumption and production SDG 12 is to: "Ensure sustainable consumption and production patterns." One of the indicators is the number of national policy instruments to promote sustainable consumption and production patterns. Another one is global fossil fuel subsidies. An increase in domestic recycling and a reduced reliance on the global plastic waste trade are other actions that might help meet the goal. Goal 13: Climate action SDG 13 is to: "Take urgent action to combat climate change and its impacts by regulating emissions and promoting developments in renewable energy." In 2021 to early 2023, the Intergovernmental Panel on Climate Change (IPCC) published its Sixth Assessment Report which assesses scientific, technical, and socio-economic information concerning climate change. Goal 14: Life below water SDG 14 is to: "Conserve and sustainably use the oceans, seas and marine resources for sustainable development." The current efforts to protect oceans, marine environments and small-scale fishers are not meeting the need to protect the resources. Increased ocean temperatures and oxygen loss act concurrently with ocean acidification to constitute the deadly trio of climate change pressures on the marine environment. Goal 15: Life on land SDG 15 is to: "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss." The proportion of remaining forest area, desertification and species extinction risk are example indicators of this goal. Goal 16: Peace, justice and strong institutions SDG 16 is to: "Promote peaceful and inclusive societies for sustainable development, provide access to justice for all and build effective, accountable and inclusive institutions at all levels." Rates of birth registration and prevalence of bribery are two examples of indicators included in this goal. Goal 17: Partnerships for the goals SDG 17 is to: "Strengthen the means of implementation and revitalize the global partnership for sustainable development." Increasing international cooperation is seen as vital to achieving each of the 16 previous goals. Developing multi-stakeholder partnerships to facilitate knowledge exchange, expertise, technology, and financial resources is recognized as critical to overall success of the SDGs. The goal includes improving north–south and South–South cooperation. Public-private partnerships which involve civil societies are specifically mentioned. Public relations The 2030 Agenda did not create specific authority for communicating the SDGs; however, both international and local advocacy organizations have pursued significant non-state resources to communicate the SDGS. UN agencies which are part of the United Nations Development Group decided to support an independent campaign to communicate the new SDGs to a wider audience. This campaign, Project Everyone, had the support of corporate institutions and other international organizations. Using the text drafted by diplomats at the UN level, a team of communication specialists developed icons for every goal. They also shortened the title The 17 Sustainable Development Goals to Global Goals, then ran workshops and conferences to communicate the Global Goals to a global audience. The Aarhus Convention is a United Nations convention passed in 2001, explicitly to encourage and promote effective public engagement in environmental decision making. Information transparency related to social media and the engagement of youth are two issues related to the Sustainable Development Goals that the convention has addressed. Advocates In 2019 and then in 2021, United Nations Secretary-General António Guterres appointed 17 SDG advocates. The role of the public figures is to raise awareness, inspire greater ambition, and push for faster action on the SDGs. The co-chairs are: Mia Mottley, Prime Minister of Barbados and Justin Trudeau, Prime Minister of Canada. Global events Global Goals Week is an annual week-long event in September for action, awareness, and accountability for the Sustainable Development Goals. It is a shared commitment for over 100 partners to ensure quick action on the SDGs by sharing ideas and transformative solutions to global problems. It first took place in 2016. It is often held concurrently with Climate Week NYC. The Arctic Film Festival is an annual film festival organized by HF Productions and supported by the SDGs' Partnership Platform. Held for the first time in 2019, the festival is expected to take place every year in September in Longyearbyen, Svalbard, Norway. History The Post-2015 Development Agenda was a process from 2012 to 2015 led by the United Nations to define the future global development framework that would succeed the Millennium Development Goals. The SDGs were developed to succeed the Millennium Development Goals (MDGs) which ended in 2015. In 1983, the United Nations created the World Commission on Environment and Development (later known as the Brundtland Commission), which defined sustainable development as "meeting the needs of the present without compromising the ability of future generations to meet their own needs." In 1992, the first United Nations Conference on Environment and Development (UNCED) or Earth Summit was held in Rio de Janeiro, where the first agenda for Environment and Development, also known as Agenda 21, was developed and adopted. In 2012, the United Nations Conference on Sustainable Development (UNCSD), also known as Rio+20, was held as a 20-year follow up to UNCED. Colombia proposed the idea of the SDGs at a preparation event for Rio+20 held in Indonesia in July 2011. In September 2011, this idea was picked up by the United Nations Department of Public Information 64th NGO Conference in Bonn, Germany. The outcome document proposed 17 sustainable development goals and associated targets. In the run-up to Rio+20 there was much discussion about the idea of the SDGs. At the Rio+20 Conference, a resolution known as "The Future We Want" was reached by member states. Among the key themes agreed on were poverty eradication, energy, water and sanitation, health, and human settlement. In January 2013, the 30-member UN General Assembly Open Working Group (OWG) on Sustainable Development Goals was established to identify specific goals for the SDGs. The OWG submitted their proposal of 8 SDGs and 169 targets to the 68th session of the General Assembly in September 2014. On 5 December 2014, the UN General Assembly accepted the Secretary General's Synthesis Report, which stated that the agenda for the post-2015 SDG process would be based on the OWG proposals. Background In 2015, the United Nations General Assembly (UNGA) created the SDGs as part of the Post-2015 Development Agenda. This agenda sought to design a new global development framework, replacing the Millennium Development Goals, which were completed that same year. These goals were formally articulated and adopted in a UNGA resolution known as the 2030 Agenda. On 6 July 2017, the SDGs were made more actionable by a UNGA resolution that identifies specific targets for each goal and provides indicators to measure progress. Most targets are to be achieved by 2030, although some have no end date. There are cross-cutting issues and synergies between the different goals; for example, for SDG 13 on climate action, the IPCC sees robust synergies with SDGs 3 (health), 7 (clean energy), 11 (cities and communities), 12 (responsible consumption and production) and 14 (oceans). On the other hand, critics and observers have also identified trade-offs between the goals,such as between ending hunger and promoting environmental sustainability. Furthermore, concerns have arisen over the high number of goals (compared to the eight Millennium Development Goals), leading to compounded trade-offs, a weak emphasis on environmental sustainability, and difficulties tracking qualitative indicators. The SDGs are monitored by the UN (United Nations) High-Level Political Forum on Sustainable Development (HLPF), an annual forum held under the auspices of the United Nations Economic and Social Council. However, the HLPF comes with its own set of problems due to a lack of political leadership and divergent national interests. To facilitate monitoring of progress on SDG implementation, the online SDG Tracker was launched in June 2018 to present all available data across all indicators. The COVID-19 pandemic had serious negative impacts on all 17 SDGs in 2020. A scientific assessment of the political impacts of the SDGs found in 2022 that the SDGs have only had limited transformative political impact thus far. At the very least, they have affected the way actors understand and communicate about sustainable development. Adoption On 25 September 2015, the 193 countries of the UN General Assembly adopted the 2030 Development Agenda titled "Transforming our world: the 2030 Agenda for Sustainable Development." This agenda has 92 paragraphs. Paragraph 59 outlines the 17 Sustainable Development Goals and the associated 169 targets and 232 indicators. The UN-led process involved its 193 Member States and global civil society. The resolution is a broad intergovernmental agreement that acts as the Post-2015 Development Agenda. The SDGs build on the principles agreed upon in Resolution A/RES/66/288, entitled "The Future We Want". This was a non-binding document released as a result of Rio+20 Conference held in 2012. Implementation Implementation of the SDGs started worldwide in 2016. This process can also be called Localizing the SDGs. In 2019 António Guterres (secretary-general of the United Nations) issued a global call for a Decade of Action to deliver the Sustainable Development Goals by 2030. This decade will last from 2020 to 2030. The plan is that the secretary general of the UN will convene an annual platform for driving the Decade of Action. There are two main types of actors for implementation of the SDGs: state and non-state actors. State actors include national governments and sub-national authorities, whereas non-state actors are corporations and civil society. Civil society participation and empowerment is important but there are also diverse interests in this group. Building new partnerships is useful. However, the SDGs are not legally binding and purposefully designed to provide much leeway for actors. Therefore, they can interpret the goals differently and often according to their interests. Cross-cutting issues The widespread consensus is that progress on all of the SDGs will be stalled if women's empowerment and gender equality are not prioritized, and treated holistically. The SDGs look to policy makers as well as private sector executives and board members to work toward gender equality. Statements from diverse sources such as the Organisation for Economic Cooperation and Development (OECD), UN Women and the World Pensions Forum, have noted that investments in women and girls have positive impacts on economies. National and global development investments in women and girls often exceed their initial scope. Gender equality is mainstreamed throughout the SDG framework by ensuring that as much sex-disaggregated data as possible are collected. Education for sustainable development (ESD) is explicitly recognized in the SDGs as part of Target 4.7 of the SDG on education. UNESCO promotes the Global Citizenship Education (GCED) as a complementary approach. Education for sustainable development is important for all the other 16 SDGs. Culture is explicitly referenced in SDG 11 Target 4 ("Strengthen efforts to protect and safeguard the world's cultural and natural heritage"). However, culture is seen as a cross-cutting theme because it impacts several SDGs. For example, culture plays a role in SDG targets where they relate to environment and resilience (within SDGs 11, 12 and 16), prosperity and livelihoods (within SDG 8), inclusion and participation (within SDG 11 and 16). SDGs 1 to 6 directly address health disparities, primarily in developing countries. These six goals address key issues in Global Public Health, Poverty, Hunger and Food security, Health, Education, Gender equality and women's empowerment, as well as water and sanitation. Public health officials can use these goals to set their own agenda and plan for smaller scale initiatives for their organizations. The links between the various sustainable development goals and public health are numerous and well established: SDG 1: Living below the poverty line is attributed to poorer health outcomes and can be even worse for persons living in developing countries where extreme poverty is more common. A child born into poverty is twice as likely to die before the age of five compared to a child from a wealthier family. SDG 2: The detrimental effects of hunger and malnutrition that can arise from systemic challenges with food security are enormous. The World Health Organization estimates that 12.9 percent of the population in developing countries is undernourished. SDG 4 and 5: Educational equity has yet to be reached in the world. Public health efforts are impeded by this, as a lack of education can lead to poorer health outcomes. This is shown by children of mothers who have no education having a lower survival rate compared to children born to mothers with primary or greater levels of education. Synergies Synergies amongst the SDGs are "the good antagonists of trade-offs."With regards to SDG 13 on climate action, the IPCC sees robust synergies particularly for the SDGs 3 (health), 7 (clean energy), 11 (cities and communities), 12 (responsible consumption and production) and 14 (oceans). To meet SDG 13 and other SDGs, sustained long-term investment in green innovation is required to: decarbonize the physical capital stock – energy, industry, and transportation infrastructure – and ensure its resilience to a changing future climate; to preserve and enhance natural capital – forests, oceans, and wetlands; and to train people to work in a climate-neutral economy. International organizations Many international organizations have committed to the SDGs since 2015. Examples for international organizations include: UN General Assembly, World Trade Organization, African Development Bank, UN Economic and Social Council, UN Security Council, Asian Development Bank. However, international organizations often have "cherry-picked" goals, engaged in selective mainstreaming, or continued to adopt policies that are barriers to goal attainment. In the case of the World Bank, it has used the growing momentum of the SDGs to further its strategic objectives without being influenced by the SDGs in turn. The bank engaged with the SDGs selectively; efforts to integrate the goals into organizational practices remained limited; and their inclusion in country-level processes is primarily voluntary. In general, the SDGs might be a low priority for international organizations that have many other assignments that are often more binding, have more urgent deliverables, and have more repercussions in case of inaction. Furthermore, the SDGs, although presented as a holistic agenda, have many internal contradictions that must be addressed in implementation. The breadth of the SDGs, covering nearly all areas of global governance, is at odds with international organizations that over time have become highly functionally differentiated and that operate through intra-organizational compromises. Most international organizations primarily see the SDGs as separate goals rather than an integrated agenda, leading to the cherry-picking of those goals that best fit their agenda. Research has shown that since the implementation of the SDGs, fragmentation among international organizations has not decreased. Instead, the formation of silos has increased around the 17 SDG issue areas as well as around the economic, social and environmental dimensions of sustainable development. Working in silos may hamper the exchange of novel ideas and knowledge amongst international organizations that is required to deal with the complex and globally interconnected problems that the SDGs aim to address. It might also limit options for joint standards, policies, and transformative norm development. Results and outcomes Most or all of the goals and targets are unlikely to be achieved by 2030. Of particular concern - which cut across many of the SDGs – are rising inequalities, ongoing climate change and increasing biodiversity loss. In addition, there is a trade-off between the planetary boundaries of Earth and the aspirations for wealth and well-being. This has been described as follows: "the world's social and natural biophysical systems cannot support the aspirations for universal human well-being embedded in the SDGs." An independent group of scientists appointed by the Secretary General, found that: "the world is far off track". This report urges "urgent course correction" to help achieve the SDGs. This report blames the lingering drag of the COVID-19 pandemic, a rise in conflicts and, inflation for the lagging progress of the SDGs. Due to various economic and social issues, many countries are seeing a major decline in the progress made. In Asia for example, data shows a loss of progress on goals 2, 8,10,11, and 15. Recommended approaches to still achieve the SDGs are: "Set priorities, focus on harnessing the environmental dimension of the SDGs, understand how the SDGs work as an indivisible system, and look for synergies." Assessing the political impact of the SDGs In 2022, a research project analyzed the political impacts of the SDGs as well as their "steering effects". The project was a "systematic meta-analysis of peer-reviewed academic literature". It reviewed over 3,000 scientific articles, mainly from the social sciences. These steering effects could be one of three types: "discursive", normative or institutional effects. The presence of all three types of effects throughout a political system was defined as transformative impact, which is the eventual goal of the 2030 Agenda. Discursive effects relate to changes in global and national debates that make them more aligned with the SDGs. Normative effects would be adjustments in legislative and regulatory frameworks and policies in line with, and because of, the SDGs. Institutional effects would be the creation of new departments, committees, offices or programs linked to the achievement of the SDGs or the realignment of existing institutions. The review found that the SDGs have had only limited transformative political impact thus far. In fact, their effects have been mainly "discursive" only. For example, the broad uptake of the principle of leaving no one behind in pronouncements by policymakers and civil society activists is a discursive effect. The SDGs have also led to some isolated normative and institutional reforms. However, there is widespread doubt that the SDGs can steer societies towards more ecological integrity at the planetary scale. This is because countries generally prioritize the more socioeconomic SDGs (e.g. SDGs 8 to 12) over the environmentally oriented ones (e.g. SDGs 13 to 15), which is in alignment with their long-standing national development policies. Impacts of COVID-19 pandemic The COVID-19 pandemic has had a profound impact on the mental and physical wellbeing of communities around the world. The pandemic slowed progress towards achieving the SDGs. It has "exacerbated existing fault lines of inequality". The brunt of the impacts of the COVID-19 pandemic were felt by poorer segments of the population. The COVID-19 pandemic in 2020 had impacts on all 17 goals. It has become "the worst human and economic crisis in a lifetime." The pandemic threatened progress made in particular for SDG 3 (health), SDG 4 (education), SDG 6 (water and sanitation for all), SDG 10 (reduce inequality) and SDG 17 (partnerships). At the UN High-level Political Forum on Sustainable Development in July 2023, speakers remarked that the pandemic, and multiple worldwide crises such as climate change, threatened decades of progress on the SDGs. Uneven priorities of goals Some goals are "left behind." These goals are hardly prioritized and rarely integrated with others. For example, the uptake of ocean and land issues into the SDGs was expected to lead to more attention and better integration of these issues with other global concerns. And yet, broader planetary concerns such as those under SDG 14 (on oceans) and SDG 15 (on land) are still side-lined in global policies, including within the United Nations system. Global and domestic inequality only barely made it into the final set of SDGs as SDG 10, and this goal is still poorly supported and often marginalized. In 2019 five progress reports on the 17 SDGs were published. Three came from the United Nations Department of Economic and Social Affairs (UNDESA), one from the Bertelsmann Foundation and one from the European Union. A review of the five reports analyzed which of the 17 Goals were addressed in priority and which ones were left behind. In explanation of the findings, the Basel Institute of Commons and Economics said Biodiversity, Peace and Social Inclusion were "left behind" by quoting the official SDGs motto "Leaving no one behind." It has been argued that governments and businesses actively prioritize the social and economic goals over the environmental goals (such as Goal 14 and 15) in both rhetoric and practice. Funding Cost estimates The United Nations estimates that for Africa, considering the continent's population growth, yearly funding of $1.3 trillion would be needed to achieve the Sustainable Development Goals in Africa. The International Monetary Fund (IMF) also estimates that $50 billion may be needed only to cover the expenses of climate adaptation. The IMF has also taken the initiative to achieve the SDGs by offering their support to developing countries. Estimates for providing clean water and sanitation for the whole population of all continents have been as high as US$200 billion. The World Bank says that estimates need to be made country by country, and reevaluated frequently over time. In 2014, UNCTAD estimated the annual costs to achieving the UN Goals at US$2.5 trillion per year. Another estimate from 2018 (by the Basel Institute of Commons and Economics, that conducts the World Social Capital Monitor) found that to reach all of the SDGs this would require between US$2.5 and $5.0 trillion per year. Allocation of funds In 2017 the UN launched the Inter-agency Task Force on Financing for Development (UN IATF on FfD) that invited to a public dialogue. The top-5 sources of financing for development were estimated in 2018 to be: Real new sovereign debt OECD countries, military expenditures, official increase sovereign debt OECD countries, remittances from expats to developing countries, official development assistance (ODA). The Rockefeller Foundation asserted in 2017 that "The key to financing and achieving the SDGs lies in mobilizing a greater share of the $200+ trillion in annual private capital investment flows toward development efforts, and philanthropy has a critical role to play in catalyzing this shift." Large-scale funders participating in a Rockefeller Foundation-hosted design thinking workshop concluded that "while there is a moral imperative to achieve the SDGs, failure is inevitable if there aren't drastic changes to how we go about financing large scale change." A meta-analysis published in 2022 found that there was scant evidence that governments have substantially reallocated funding to implement the SDGs, either for national implementation or for international cooperation. The SDGs do not seem to have changed public budgets and financial allocation mechanisms in any important way, except for some local governance contexts. National budgets cannot easily be reallocated. SDG-driven investment Capital stewardship is expected to play a crucial part in the progressive advancement of the SDG agenda to "shift the economic system towards sustainable investment by using the SDG framework across all asset classes." The notion of SDG Driven Investment gained further ground amongst institutional investors in 2019. In 2017, 2018 and early 2019, the World Pensions Council (WPC) held a series of ESG-focused (Environmental, Social and Governance) discussions with pension board members (trustees) and senior investment executives from across G20 nations. Many pension investment executives and board members confirmed they were in the process of adopting or developing SDG-informed investment processes, with more ambitious investment governance requirements – notably when it comes to climate action, gender equality and social fairness. Some studies, however, warn of selective implementation of SDGs and political risks linked to private investments in the context of continued shortage of public funding. Measuring progress Monitoring tools and websites The online publication SDG-Tracker was launched in June 2018 and presents data across all available indicators. It relies on the Our World in Data database and is also based at the University of Oxford. The publication has global coverage and tracks whether the world is making progress towards the SDGs. It aims to make the data on the 17 goals available and understandable to a wide audience. The SDG-Tracker highlights that the world is currently (early 2019) very far away from achieving the goals. The Global SDG Index and Dashboards Report is the first publication to track countries' performance on all 17 Sustainable Development Goals. The annual publication, co-produced by Bertelsmann Stiftung and SDSN, includes a ranking and dashboards that show key challenges for each country in terms of implementing the SDGs. The publication also shows an analysis of government efforts to implement the SDGs. UN High-Level Political Forum on Sustainable Development (HLPF) This subdivision should be a "regular meeting place for governments and non-state representatives to assess global progress towards sustainable development." The meetings take place under the auspices of the United Nations economic and Social Council. In July 2020 the meeting took place online for the first time due to the COVID-19 pandemic. The theme was "Accelerated action and transformative pathways: realizing the decade of action and delivery for sustainable development" and a ministerial declaration was adopted. High-level progress reports for all the SDGs are published in the form of reports by the United Nations Secretary General. The most recent one is from April 2020. However, the HLPF has a range of problems. It has not been able to promote system-wide coherence. The reasons for this include its broad and unclear mandate combined with a lack of resources and divergent national interests. Therefore, this reporting system is mainly just a platform for voluntary reporting and peer learning among governments. The High-level Political Forum on Sustainable Development (HLPF) replaced the United Nations Commission on Sustainable Development in 2012. Challenges Too many goals and overall problems Scholars have pointed out flaws in the design of the SDGs for the following aspects: "the number of goals, the structure of the goal framework (for example, the non-hierarchical structure), the coherence between the goals, the specificity or measurability of the targets, the language used in the text, and their reliance on neoliberal economic development-oriented sustainable development as their core orientation." The SDGs may simply maintain the status quo and fall short of delivering an ambitious development agenda. The current status quo has been described as "separating human wellbeing and environmental sustainability, failing to change governance and to pay attention to trade-offs, root causes of poverty and environmental degradation, and social justice issues." A commentary in The Economist in 2015 argued that 169 targets for the SDGs is too many, describing them as sprawling, misconceived and a mess compared to the eight Millennium Development Goals (MDGs). The SDGs are internally incoherent, with some inherently conflictive targets, and many interdependencies between the targets are context-specific. Weak on environmental sustainability Scholars have criticized that the SDGs "fail to recognize that planetary, people and prosperity concerns are all part of one earth system, and that the protection of planetary integrity should not be a means to an end, but an end in itself." The SDGs "remain fixated on the idea that economic growth is foundational to achieve all pillars of sustainable development." They do not prioritize environmental protection. The SDGs include three environment-focused SDGs, which are Goal 13, 14 and 15 (climate, land and oceans), but there is no overarching environmental or planetary goal. The SDGs do not pursue planetary integrity as such.Other SDGs, which as Goal 7, 12 and 13 ignore the planetary limits and encourage consumption Environmental constraints and planetary boundaries are underrepresented within the SDGs. For instance, the way the current SDGs are structured leads to a negative correlation between environmental sustainability and SDGs, with most indicators within even the sustainability-focused goals focusing on social or economic outcomes. This helps further the denial that there are absolute limits to economic growth. They could unintentionally promote environmental destruction in the name of sustainable development. Certain studies also argue that the focus of the SDGs on neoliberal sustainable development is detrimental to planetary integrity and justice. Both of these ambitions (planetary integrity and justice) would require limits to economic growth.This helps further the denial that there are absolute limits to economic growth. These studies question whether economic growth and ecological sustainability go hand in hand. Scientists have proposed several ways to address the weaknesses regarding environmental sustainability in the SDGs: The monitoring of essential variables to better capture the essence of coupled environmental and social systems that underpin sustainable development, helping to guide coordination and systems transformation. More attention to the context of the biophysical systems in different places (e.g., coastal river deltas, mountain areas) Better understanding of feedbacks across scales in space (e.g., through globalization) and time (e.g., affecting future generations) that could ultimately determine the success or failure of the SDGs. Reframing the message of the SDGs to help advocate to limits to growth rather than the empirically unfounded idea that economic growth can continue in a limited world. Reformulating specific goals that emphasis reduced consumption instead of the business as usual model. Ethical aspects There are concerns about the ethical orientation of the SDGs: they remain "underpinned by strong (Western) modernist notions of development: sovereignty of humans over their environment (anthropocentricism), individualism, competition, freedom (rights rather than duties), self-interest, belief in the market leading to collective welfare, private property (protected by legal systems), rewards based on merit, materialism, quantification of value, and instrumentalization of labor.":453 The SDGs have been criticized for furthering a neoliberal agenda that extends to promote neoliberal and business interests. Furthermore, the framework represents a universal template grounded in Western ideology. This framework is then used to reproduce a flawed Western paradigm. Some scientists worry that the SDGs could be used against legitimate protests about development initiatives. Some studies warn that the SDGs could be used to camouflage business-as-usual by disguising it using SDG-related sustainability rhetoric. A meta-analysis review study in 2022 found that: "There is even emerging evidence that the SDGs might have even adverse effects, by providing a "smokescreen of hectic political activity" that blurs a reality of stagnation, dead ends and business-as-usual." Difficulties with tracking qualitative indicators Regarding the targets of the SDGs, there is generally weak evidence linking the means of implementation to outcomes. The targets about means of implementation (those denoted with a letter, for example, Target 6.a) are imperfectly conceptualized and inconsistently formulated, and tracking their largely qualitative indicators will be difficult. Trade-offs and priorities The trade-offs among the 17 SDGs might prevent their realization. For example, these are three difficult trade-offs to consider: "How can ending hunger be reconciled with environmental sustainability? (SDG targets 2.3 and 15.2) How can economic growth be reconciled with environmental sustainability? (SDG targets 9.2 and 9.4) How can income inequality be reconciled with economic growth? (SDG targets 10.1 and 8.1)." The SDGs do not specifically address the tensions between economic growth and environmental sustainability. Instead, they emphasize "longstanding but dubious claims about decoupling and resource efficiency as technological solutions to the environmental crisis." For example, continued global economic growth of 3 percent (SDG 8) may not be reconcilable with ecological sustainability goals, because the required rate of absolute global eco-economic decoupling is far higher than any country has achieved in the past. Without attention to potential negative trade-offs between goals, selective implementation may undermine rather than support the implementation of the SDGs. To ensure that some SDGs do not fall behind, new efforts at prioritization are needed. While a "hard" prioritization of one goal over another (e.g., if there is a trade-off between SDG x and SDG y, SDG x must always be chosen) is politically unlikely, guidelines for "soft prioritization" may be created. For example, determining minimum progress thresholds for each SDG target could be a useful approach: should progress under one target fall under this assigned threshold, the target would immediately get priority, and specific policies would be triggered to increase target achievement. Examples of progress A study in 2024 predicted SDG scores of regions until 2030 using machine learning models. The forecast results for 2030 show that "OECD countries" (80) (with a 2.8% change) and "Eastern Europe and Central Asia" (74) (with a 2.37% change) are expected to achieve the highest SDG scores. "Latin America and the Caribbean" (73) (with a 4.17% change), "East and South Asia" (69) (with a 2.64% change), "Middle East and North Africa" (68) (with a 2.32% change), and "Sub-Saharan Africa" (56) (with a 7.2% change) will display lower levels of SDG achievement, respectively. Asia and Pacific Australia China UN Secretary General Guterres has praised China's Belt and Road Initiative for its capacity to advance the sustainable development goals. Institutional connections between the BRI and multiple UN bodies have also been established. Africa The United Nations Development Programme (UNDP) has collected information to show how awareness about the SDGs among government officers, civil society and others has been created in many African countries. Nigeria Europe and Middle East Baltic nations, via the Council of the Baltic Sea States, have created the Baltic 2030 Action Plan. Lebanon Syria Higher education in Syria began with sustainable development steps through Damascus University. United Kingdom The UK's approach to delivering the Global SDGs is outlined in Agenda 2030: Delivering the Global Goals, developed by the Department for International Development. In 2019, the Bond network analyzed the UK's global progress on the Sustainable Development Goals (SDGs). The Bond report highlights crucial gaps where attention and investment are most needed. The report was compiled by 49 organizations and 14 networks and working groups.

Water cycle

The water cycle (or hydrologic cycle or hydrological cycle), is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time. However, the partitioning of the water into the major reservoirs of ice, fresh water, salt water and atmospheric water is variable and depends on climatic variables. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere. The processes that drive these movements are evaporation, transpiration, condensation, precipitation, sublimation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor. The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation. The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment. These heat exchanges influence the climate system. The evaporative phase of the cycle purifies water because it causes salts and other solids picked up during the cycle to be left behind. The condensation phase in the atmosphere replenishes the land with freshwater. The flow of liquid water and ice transports minerals across the globe. It also reshapes the geological features of the Earth, through processes including erosion and sedimentation. The water cycle is also essential for the maintenance of most life and ecosystems on the planet. Human actions are greatly affecting the water cycle. Activities such as deforestation, urbanization, and the extraction of groundwater are altering natural landscapes (land use changes) all have an effect on the water cycle. On top of this, climate change is leading to an intensification of the water cycle. Research has shown that global warming is causing shifts in precipitation patterns, increased frequency of extreme weather events, and changes in the timing and intensity of rainfall. These water cycle changes affect ecosystems, water availability, agriculture, and human societies. Description Overall process The water cycle is powered from the energy emitted by the sun. This energy heats water in the ocean and seas. Water evaporates as water vapor into the air. Some ice and snow sublimates directly into water vapor. Evapotranspiration is water transpired from plants and evaporated from the soil. The water molecule has smaller molecular mass than the major components of the atmosphere, nitrogen and oxygen and hence is less dense. Due to the significant difference in density, buoyancy drives humid air higher. As altitude increases, air pressure decreases and the temperature drops (see Gas laws). The lower temperature causes water vapor to condense into tiny liquid water droplets which are heavier than the air, and which fall unless supported by an updraft. A huge concentration of these droplets over a large area in the atmosphere becomes visible as cloud, while condensation near ground level is referred to as fog. Atmospheric circulation moves water vapor around the globe; cloud particles collide, grow, and fall out of the upper atmospheric layers as precipitation. Some precipitation falls as snow, hail, or sleet, and can accumulate in ice caps and glaciers, which can store frozen water for thousands of years. Most water falls as rain back into the ocean or onto land, where the water flows over the ground as surface runoff. A portion of this runoff enters rivers, with streamflow moving water towards the oceans. Runoff and water emerging from the ground (groundwater) may be stored as freshwater in lakes. Not all runoff flows into rivers; much of it soaks into the ground as infiltration. Some water infiltrates deep into the ground and replenishes aquifers, which can store freshwater for long periods of time. Some infiltration stays close to the land surface and can seep back into surface-water bodies (and the ocean) as groundwater discharge or be taken up by plants and transferred back to the atmosphere as water vapor by transpiration. Some groundwater finds openings in the land surface and emerges as freshwater springs. In river valleys and floodplains, there is often continuous water exchange between surface water and ground water in the hyporheic zone. Over time, the water returns to the ocean, to continue the water cycle. The ocean plays a key role in the water cycle. The ocean holds "97% of the total water on the planet; 78% of global precipitation occurs over the ocean, and it is the source of 86% of global evaporation". Important physical processes within the water cycle include (in alphabetical order): Advection: The movement of water through the atmosphere. Without advection, water that evaporated over the oceans could not precipitate over land. Atmospheric rivers that move large volumes of water vapor over long distances are an example of advection. Condensation: The transformation of water vapor to liquid water droplets in the air, creating clouds and fog. Evaporation: The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere. The source of energy for evaporation is primarily solar radiation. Evaporation often implicitly includes transpiration from plants, though together they are specifically referred to as evapotranspiration. Total annual evapotranspiration amounts to approximately of water, of which evaporates from the oceans. 86% of global evaporation occurs over the ocean. Infiltration: The flow of water from the ground surface into the ground. Once infiltrated, the water becomes soil moisture or groundwater. A recent global study using water stable isotopes, however, shows that not all soil moisture is equally available for groundwater recharge or for plant transpiration. Percolation: Water flows vertically through the soil and rocks under the influence of gravity. Precipitation: Condensed water vapor that falls to the Earth's surface. Most precipitation occurs as rain, but also includes snow, hail, fog drip, graupel, and sleet. Approximately of water falls as precipitation each year, of it over the oceans. The rain on land contains of water per year and a snowing only . 78% of global precipitation occurs over the ocean. Runoff: The variety of ways by which water moves across the land. This includes both surface runoff and channel runoff. As it flows, the water may seep into the ground, evaporate into the air, become stored in lakes or reservoirs, or be extracted for agricultural or other human uses. Subsurface flow: The flow of water underground, in the vadose zone and aquifers. Subsurface water may return to the surface (e.g. as a spring or by being pumped) or eventually seep into the oceans. Water returns to the land surface at lower elevation than where it infiltrated, under the force of gravity or gravity induced pressures. Groundwater tends to move slowly and is replenished slowly, so it can remain in aquifers for thousands of years. Transpiration: The release of water vapor from plants and soil into the air. Residence times The residence time of a reservoir within the hydrologic cycle is the average time a water molecule will spend in that reservoir (see table). It is a measure of the average age of the water in that reservoir. Groundwater can spend over 10,000 years beneath Earth's surface before leaving. Particularly old groundwater is called fossil water. Water stored in the soil remains there very briefly, because it is spread thinly across the Earth, and is readily lost by evaporation, transpiration, stream flow, or groundwater recharge. After evaporating, the residence time in the atmosphere is about 9 days before condensing and falling to the Earth as precipitation. The major ice sheets – Antarctica and Greenland – store ice for very long periods. Ice from Antarctica has been reliably dated to 800,000 years before present, though the average residence time is shorter. In hydrology, residence times can be estimated in two ways. The more common method relies on the principle of conservation of mass (water balance) and assumes the amount of water in a given reservoir is roughly constant. With this method, residence times are estimated by dividing the volume of the reservoir by the rate by which water either enters or exits the reservoir. Conceptually, this is equivalent to timing how long it would take the reservoir to become filled from empty if no water were to leave (or how long it would take the reservoir to empty from full if no water were to enter). An alternative method to estimate residence times, which is gaining in popularity for dating groundwater, is the use of isotopic techniques. This is done in the subfield of isotope hydrology. Water in storage The water cycle describes the processes that drive the movement of water throughout the hydrosphere. However, much more water is "in storage" (or in "pools") for long periods of time than is actually moving through the cycle. The storehouses for the vast majority of all water on Earth are the oceans. It is estimated that of the 1,386,000,000 km3 of the world's water supply, about 1,338,000,000 km3 is stored in oceans, or about 97%. It is also estimated that the oceans supply about 90% of the evaporated water that goes into the water cycle. The Earth's ice caps, glaciers, and permanent snowpack stores another 24,064,000 km3 accounting for only 1.7% of the planet's total water volume. However, this quantity of water is 68.7% of all freshwater on the planet. Changes caused by humans Local or regional impacts Human activities can alter the water cycle at the local or regional level. This happens due to changes in land use and land cover. Such changes affect "precipitation, evaporation, flooding, groundwater, and the availability of freshwater for a variety of uses". Examples for such land use changes are converting fields to urban areas or clearing forests. Such changes can affect the ability of soils to soak up surface water. Deforestation has local as well as regional effects. For example it reduces soil moisture, evaporation and rainfall at the local level. Furthermore, deforestation causes regional temperature changes that can affect rainfall patterns. Aquifer drawdown or overdrafting and the pumping of fossil water increase the total amount of water in the hydrosphere. This is because the water that was originally in the ground has now become available for evaporation as it is now in contact with the atmosphere. Water cycle intensification due to climate change Since the middle of the 20th century, human-caused climate change has resulted in observable changes in the global water cycle. The IPCC Sixth Assessment Report in 2021 predicted that these changes will continue to grow significantly at the global and regional level. These findings are a continuation of scientific consensus expressed in the IPCC Fifth Assessment Report from 2007 and other special reports by the Intergovernmental Panel on Climate Change which had already stated that the water cycle will continue to intensify throughout the 21st century. Related processes Biogeochemical cycling While the water cycle is itself a biogeochemical cycle, flow of water over and beneath the Earth is a key component of the cycling of other biogeochemicals. Runoff is responsible for almost all of the transport of eroded sediment and phosphorus from land to waterbodies. The salinity of the oceans is derived from erosion and transport of dissolved salts from the land. Cultural eutrophication of lakes is primarily due to phosphorus, applied in excess to agricultural fields in fertilizers, and then transported overland and down rivers. Both runoff and groundwater flow play significant roles in transporting nitrogen from the land to waterbodies. The dead zone at the outlet of the Mississippi River is a consequence of nitrates from fertilizer being carried off agricultural fields and funnelled down the river system to the Gulf of Mexico. Runoff also plays a part in the carbon cycle, again through the transport of eroded rock and soil. Slow loss over geologic time The hydrodynamic wind within the upper portion of a planet's atmosphere allows light chemical elements such as Hydrogen to move up to the exobase, the lower limit of the exosphere, where the gases can then reach escape velocity, entering outer space without impacting other particles of gas. This type of gas loss from a planet into space is known as planetary wind. Planets with hot lower atmospheres could result in humid upper atmospheres that accelerate the loss of hydrogen. Historical interpretations In ancient times, it was widely thought that the land mass floated on a body of water, and that most of the water in rivers has its origin under the earth. Examples of this belief can be found in the works of Homer. In Works and Days (ca. 700 BC), the Greek poet Hesiod outlines the idea of the water cycle: "[Vapour] is drawn from the ever-flowing rivers and is raised high above the earth by windstorm, and sometimes it turns to rain towards evening, and sometimes to wind when Thracian Boreas huddles the thick clouds." In the ancient Near East, Hebrew scholars observed that even though the rivers ran into the sea, the sea never became full. Some scholars conclude that the water cycle was described completely during this time in this passage: "The wind goeth toward the south, and turneth about unto the north; it whirleth about continually, and the wind returneth again according to its circuits. All the rivers run into the sea, yet the sea is not full; unto the place from whence the rivers come, thither they return again" (Ecclesiastes 1:6-7). Furthermore, it was also observed that when the clouds were full, they emptied rain on the earth (Ecclesiastes 11:3). In the Adityahridayam (a devotional hymn to the Sun God) of Ramayana, a Hindu epic dated to the 4th century BCE, it is mentioned in the 22nd verse that the Sun heats up water and sends it down as rain. By roughly 500 BCE, Greek scholars were speculating that much of the water in rivers can be attributed to rain. The origin of rain was also known by then. These scholars maintained the belief, however, that water rising up through the earth contributed a great deal to rivers. Examples of this thinking included Anaximander (570 BCE) (who also speculated about the evolution of land animals from fish) and Xenophanes of Colophon (530 BCE). Warring States period Chinese scholars such as Chi Ni Tzu (320 BCE) and Lu Shih Ch'un Ch'iu (239 BCE) had similar thoughts. The idea that the water cycle is a closed cycle can be found in the works of Anaxagoras of Clazomenae (460 BCE) and Diogenes of Apollonia (460 BCE). Both Plato (390 BCE) and Aristotle (350 BCE) speculated about percolation as part of the water cycle. Aristotle correctly hypothesized that the sun played a role in the Earth's hydraulic cycle in his book Meteorology, writing "By it [the sun's] agency the finest and sweetest water is everyday carried up and is dissolved into vapor and rises to the upper regions, where it is condensed again by the cold and so returns to the earth.", and believed that clouds were composed of cooled and condensed water vapor. Much like the earlier Aristotle, the Eastern Han Chinese scientist Wang Chong (27–100 AD) accurately described the water cycle of Earth in his Lunheng but was dismissed by his contemporaries. Up to the time of the Renaissance, it was wrongly assumed that precipitation alone was insufficient to feed rivers, for a complete water cycle, and that underground water pushing upwards from the oceans were the main contributors to river water. Bartholomew of England held this view (1240 CE), as did Leonardo da Vinci (1500 CE) and Athanasius Kircher (1644 CE). Discovery of the correct theory The first published thinker to assert that rainfall alone was sufficient for the maintenance of rivers was Bernard Palissy (1580 CE), who is often credited as the discoverer of the modern theory of the water cycle. Palissy's theories were not tested scientifically until 1674, in a study commonly attributed to Pierre Perrault. Even then, these beliefs were not accepted in mainstream science until the early nineteenth century.

Ethics

Ethics is the philosophical study of moral phenomena. Also called moral philosophy, it investigates normative questions about what people ought to do or which behavior is morally right. Its main branches include normative ethics, applied ethics, and metaethics. Normative ethics aims to find general principles that govern how people should act. Applied ethics examines concrete ethical problems in real-life situations, such as abortion, treatment of animals, and business practices. Metaethics explores the underlying assumptions and concepts of ethics. It asks whether there are objective moral facts, how moral knowledge is possible, and how moral judgments motivate people. Influential normative theories are consequentialism, deontology, and virtue ethics. According to consequentialists, an act is right if it leads to the best consequences. Deontologists focus on acts themselves, saying that they must adhere to duties, like telling the truth and keeping promises. Virtue ethics sees the manifestation of virtues, like courage and compassion, as the fundamental principle of morality. Ethics is closely connected to value theory, which studies the nature and types of value, like the contrast between intrinsic and instrumental value. Moral psychology is a related empirical field and investigates psychological processes involved in morality, such as reasoning and the formation of character. Descriptive ethics describes the dominant moral codes and beliefs in different societies and considers their historical dimension. The history of ethics started in the ancient period with the development of ethical principles and theories in ancient Egypt, India, China, and Greece. This period saw the emergence of ethical teachings associated with Hinduism, Buddhism, Confucianism, Daoism, and contributions of philosophers like Socrates and Aristotle. During the medieval period, ethical thought was strongly influenced by religious teachings. In the modern period, this focus shifted to a more secular approach concerned with moral experience, reasons for acting, and the consequences of actions. An influential development in the 20th century was the emergence of metaethics. Definition Ethics, also called moral philosophy, is the study of moral phenomena. It is one of the main branches of philosophy and investigates the nature of morality and the principles that govern the moral evaluation of conduct, character traits, and institutions. It examines what obligations people have, what behavior is right and wrong, and how to lead a good life. Some of its key questions are "How should one live?" and "What gives meaning to life?". In contemporary philosophy, ethics is usually divided into normative ethics, applied ethics, and metaethics. Morality is about what people ought to do rather than what they actually do, what they want to do, or what social conventions require. As a rational and systematic field of inquiry, ethics studies practical reasons why people should act one way rather than another. Most ethical theories seek universal principles that express a general standpoint of what is objectively right and wrong. In a slightly different sense, the term ethics can also refer to individual ethical theories in the form of a rational system of moral principles, such as Aristotelian ethics, and to a moral code that certain societies, social groups, or professions follow, as in Protestant work ethic and medical ethics. The English word ethics has its roots in the Ancient Greek word , meaning and . This word gave rise to the Ancient Greek word , which was translated into Latin as and entered the English language in the 15th century through the Old French term . The term morality originates in the Latin word , meaning and . It was introduced into the English language during the Middle English period through the Old French term . The terms ethics and morality are usually used interchangeably but some philosophers distinguish between the two. According to one view, morality focuses on what moral obligations people have while ethics is broader and includes ideas about what is good and how to lead a meaningful life. Another difference is that codes of conduct in specific areas, such as business and environment, are usually termed ethics rather than morality, as in business ethics and environmental ethics. Normative ethics Normative ethics is the philosophical study of ethical conduct and investigates the fundamental principles of morality. It aims to discover and justify general answers to questions like "How should one live?" and "How should people act?", usually in the form of universal or domain-independent principles that determine whether an act is right or wrong. For example, given the particular impression that it is wrong to set a child on fire for fun, normative ethics aims to find more general principles that explain why this is the case, like the principle that one should not cause extreme suffering to the innocent, which may itself be explained in terms of a more general principle. Many theories of normative ethics also aim to guide behavior by helping people make moral decisions. Theories in normative ethics state how people should act or what kind of behavior is correct. They do not aim to describe how people normally act, what moral beliefs ordinary people have, how these beliefs change over time, or what ethical codes are upheld in certain social groups. These topics belong to descriptive ethics and are studied in fields like anthropology, sociology, and history rather than normative ethics. Some systems of normative ethics arrive at a single principle covering all possible cases. Others encompass a small set of basic rules that address all or at least the most important moral considerations. One difficulty for systems with several basic principles is that these principles may conflict with each other in some cases and lead to ethical dilemmas. Distinct theories in normative ethics suggest different principles as the foundation of morality. The three most influential schools of thought are consequentialism, deontology, and virtue ethics. These schools are usually presented as exclusive alternatives, but depending on how they are defined, they can overlap and do not necessarily exclude one another. In some cases, they differ in which acts they see as right or wrong. In other cases, they recommend the same course of action but provide different justifications for why it is right. Consequentialism Consequentialism, also called teleological ethics, says that morality depends on consequences. According to the most common view, an act is right if it brings the best future. This means that there is no alternative course of action that has better consequences. A key aspect of consequentialist theories is that they provide a characterization of what is good and then define what is right in terms of what is good. For example, classical utilitarianism says that pleasure is good and that the action leading to the most overall pleasure is right. Consequentialism has been discussed indirectly since the formulation of classical utilitarianism in the late 18th century. A more explicit analysis of this view happened in the 20th century, when the term was coined by G. E. M. Anscombe. Consequentialists usually understand the consequences of an action in a very wide sense that includes the totality of its effects. This is based on the idea that actions make a difference in the world by bringing about a causal chain of events that would not have existed otherwise. A core intuition behind consequentialism is that the future should be shaped to achieve the best possible outcome. The act itself is usually not seen as part of the consequences. This means that if an act has intrinsic value or disvalue, it is not included as a factor. Some consequentialists see this as a flaw, saying that all value-relevant factors need to be considered. They try to avoid this complication by including the act itself as part of the consequences. A related approach is to characterize consequentialism not in terms of consequences but in terms of outcome, with the outcome being defined as the act together with its consequences. Most forms of consequentialism are agent-neutral. This means that the value of consequences is assessed from a neutral perspective, that is, acts should have consequences that are good in general and not just good for the agent. It is controversial whether agent-relative moral theories, like ethical egoism, should be considered as types of consequentialism. Types There are many different types of consequentialism. They differ based on what type of entity they evaluate, what consequences they take into consideration, and how they determine the value of consequences. Most theories assess the moral value of acts. However, consequentialism can also be used to evaluate motives, character traits, rules, and policies. Many types assess the value of consequences based on whether they promote happiness or suffering. But there are also alternative evaluative principles, such as desire satisfaction, autonomy, freedom, knowledge, friendship, beauty, and self-perfection. Some forms of consequentialism hold that there is only a single source of value. The most prominent among them is utilitarianism, which states that the moral value of acts only depends on the pleasure and suffering they cause. An alternative approach says that there are many different sources of value, which all contribute to one overall value. Before the 20th century, consequentialists were only concerned with the total of value or the aggregate good. In the 20th century, alternative views were developed that additionally consider the distribution of value. One of them states that an equal distribution of goods is better than an unequal distribution even if the aggregate good is the same. There are disagreements about which consequences should be assessed. An important distinction is between act consequentialism and rule consequentialism. According to act consequentialism, the consequences of an act determine its moral value. This means that there is a direct relation between the consequences of an act and its moral value. Rule consequentialism, by contrast, holds that an act is right if it follows a certain set of rules. Rule consequentialism determines the best rules by considering their outcomes at a community level. People should follow the rules that lead to the best consequences when everyone in the community follows them. This implies that the relation between an act and its consequences is indirect. For example, if telling the truth is one of the best rules, then according to rule consequentialism, a person should tell the truth even in specific cases where lying would lead to better consequences. Another disagreement is between actual and expected consequentialism. According to the traditional view, only the actual consequences of an act affect its moral value. One difficulty of this view is that many consequences cannot be known in advance. This means that in some cases, even well-planned and intentioned acts are morally wrong if they inadvertently lead to negative outcomes. An alternative perspective states that what matters are not the actual consequences but the expected consequences. This view takes into account that when deciding what to do, people have to rely on their limited knowledge of the total consequences of their actions. According to this view, a course of action has positive moral value despite leading to an overall negative outcome if it had the highest expected value, for example, because the negative outcome could not be anticipated or was unlikely. A further difference is between maximizing and satisficing consequentialism. According to maximizing consequentialism, only the best possible act is morally permitted. This means that acts with positive consequences are wrong if there are alternatives with even better consequences. One criticism of maximizing consequentialism is that it demands too much by requiring that people do significantly more than they are socially expected to. For example, if the best action for someone with a good salary would be to donate 70% of their income to charity, it would be morally wrong for them to only donate 65%. Satisficing consequentialism, by contrast, only requires that an act is "good enough" even if it is not the best possible alternative. According to this view, it is possible to do more than one is morally required to do. Mohism in ancient Chinese philosophy is one of the earliest forms of consequentialism. It arose in the 5th century BCE and argued that political action should promote justice as a means to increase the welfare of the people. Utilitarianism The most well-known form of consequentialism is utilitarianism. In its classical form, it is an act consequentialism that sees happiness as the only source of intrinsic value. This means that an act is morally right if it produces "the greatest good for the greatest number" by increasing happiness and reducing suffering. Utilitarians do not deny that other things also have value, like health, friendship, and knowledge. However, they deny that these things have intrinsic value. Instead, they say that they have extrinsic value because they affect happiness and suffering. In this regard, they are desirable as a means but, unlike happiness, not as an end. The view that pleasure is the only thing with intrinsic value is called ethical or evaluative hedonism. Classical utilitarianism was initially formulated by Jeremy Bentham at the end of the 18th century and further developed by John Stuart Mill. Bentham introduced the hedonic calculus to assess the value of consequences. Two key aspects of the hedonic calculus are the intensity and the duration of pleasure. According to this view, a pleasurable experience has a high value if it has a high intensity and lasts for a long time. A common criticism of Bentham's utilitarianism argued that its focus on the intensity of pleasure promotes an immoral lifestyle centered around indulgence in sensory gratification. Mill responded to this criticism by distinguishing between higher and lower pleasures. He stated that higher pleasures, like the intellectual satisfaction of reading a book, are more valuable than lower pleasures, like the sensory enjoyment of food and drink, even if their intensity and duration are the same. Since its original formulation, many variations of utilitarianism have developed, including the difference between act and rule utilitarianism and between maximizing and satisficing utilitarianism. Deontology Deontology assesses the moral rightness of actions based on a set of norms or principles. These norms describe the requirements that all actions need to follow. They may include principles like telling the truth, keeping promises, and not intentionally harming others. Unlike consequentialists, deontologists hold that the validity of general moral principles does not directly depend on their consequences. They state that these principles should be followed in every case since they express how actions are inherently right or wrong. According to moral philosopher David Ross, it is wrong to break a promise even if no harm comes from it. Deontologists are interested in which actions are right and often allow that there is a gap between what is right and what is good. Many focus on prohibitions and describe which acts are forbidden under any circumstances. Agent-centered and patient-centered Agent-centered deontological theories focus on the person who acts and the duties they have. Agent-centered theories often focus on the motives and intentions behind people's actions, highlighting the importance of acting for the right reasons. They tend to be agent-relative, meaning that the reasons for which people should act depend on personal circumstances. For example, a parent has a special obligation to their child, while a stranger does not have this kind of obligation toward a child they do not know. Patient-centered theories, by contrast, focus on the people affected by actions and the rights they have. An example is the requirement to treat other people as ends and not merely as a means to an end. This requirement can be used to argue, for example, that it is wrong to kill a person against their will even if this act would save the lives of several others. Patient-centered deontological theories are usually agent-neutral, meaning that they apply equally to everyone in a situation, regardless of their specific role or position. Kantianism Immanuel Kant (1724–1804) is one of the most well-known deontologists. He states that reaching outcomes that people desire, such as being happy, is not the main purpose of moral actions. Instead, he argues that there are universal principles that apply to everyone independent of their desires. He uses the term categorical imperative for these principles, saying that they have their source in the structure of practical reason and are true for all rational agents. According to Kant, to act morally is to act in agreement with reason as expressed by these principles while violating them is both immoral and irrational. Kant provided several formulations of the categorical imperative. One formulation says that a person should only follow maxims that can be universalized. This means that the person would want everyone to follow the same maxim as a universal law applicable to everyone. Another formulation states that one should treat other people always as ends in themselves and never as mere means to an end. This formulation focuses on respecting and valuing other people for their own sake rather than using them in the pursuit of personal goals. In either case, Kant says that what matters is to have a good will. A person has a good will if they respect the moral law and form their intentions and motives in agreement with it. Kant states that actions motivated in such a way are unconditionally good, meaning that they are good even in cases where they result in undesirable consequences. Others Divine command theory says that God is the source of morality. It states that moral laws are divine commands and that to act morally is to obey and follow God's will. While all divine command theorists agree that morality depends on God, there are disagreements about the precise content of the divine commands, and theorists belonging to different religions tend to propose different moral laws. For example, Christian and Jewish divine command theorists may argue that the Ten Commandments express God's will while Muslims may reserve this role for the teachings of the Quran. Contractualists reject the reference to God as the source of morality and argue instead that morality is based on an explicit or implicit social contract between humans. They state that actual or hypothetical consent to this contract is the source of moral norms and duties. To determine which duties people have, contractualists often rely on a thought experiment about what rational people under ideal circumstances would agree on. For example, if they would agree that people should not lie then there is a moral obligation to refrain from lying. Because it relies on consent, contractualism is often understood as a patient-centered form of deontology. Famous social contract theorists include Thomas Hobbes, John Locke, Jean-Jacques Rousseau, and John Rawls. Discourse ethics also focuses on social agreement on moral norms but says that this agreement is based on communicative rationality. It aims to arrive at moral norms for pluralistic modern societies that encompass a diversity of viewpoints. A universal moral norm is seen as valid if all rational discourse participants do or would approve. This way, morality is not imposed by a single moral authority but arises from the moral discourse within society. This discourse should aim to establish an ideal speech situation to ensure fairness and inclusivity. In particular, this means that discourse participants are free to voice their different opinions without coercion but are at the same time required to justify them using rational argumentation. Virtue ethics The main concern of virtue ethics is how virtues are expressed in actions. As such, it is neither directly interested in the consequences of actions nor in universal moral duties. Virtues are positive character traits like honesty, courage, kindness, and compassion. They are usually understood as dispositions to feel, decide, and act in a certain manner by being wholeheartedly committed to this manner. Virtues contrast with vices, which are their harmful counterparts. Virtue theorists usually say that the mere possession of virtues by itself is not sufficient. Instead, people should manifest virtues in their actions. An important factor is the practical wisdom, also called phronesis, of knowing when, how, and which virtue to express. For example, a lack of practical wisdom may lead courageous people to perform morally wrong actions by taking unnecessary risks that should better be avoided. Different types of virtue ethics differ on how they understand virtues and their role in practical life. Eudaimonism is the original form of virtue theory developed in Ancient Greek philosophy and draws a close relation between virtuous behavior and happiness. It states that people flourish by living a virtuous life. Eudaimonist theories often hold that virtues are positive potentials residing in human nature and that actualizing these potentials results in leading a good and happy life. Agent-based theories, by contrast, see happiness only as a side effect and focus instead on the admirable traits and motivational characteristics expressed while acting. This is often combined with the idea that one can learn from exceptional individuals what those characteristics are. Feminist ethics of care are another form of virtue ethics. They emphasize the importance of interpersonal relationships and say that benevolence by caring for the well-being of others is one of the key virtues. Influential schools of virtue ethics in ancient philosophy were Aristotelianism and Stoicism. According to Aristotle (384–322 BCE), each virtue is a golden mean between two types of vices: excess and deficiency. For example, courage is a virtue that lies between the deficient state of cowardice and the excessive state of recklessness. Aristotle held that virtuous action leads to happiness and makes people flourish in life. Stoicism emerged about 300 BCE and taught that, through virtue alone, people can achieve happiness characterized by a peaceful state of mind free from emotional disturbances. The Stoics advocated rationality and self-mastery to achieve this state. In the 20th century, virtue ethics experienced a resurgence thanks to philosophers such as Elizabeth Anscombe, Philippa Foot, Alasdair MacIntyre, and Martha Nussbaum. Other traditions There are many other schools of normative ethics in addition to the three main traditions. Pragmatist ethics focuses on the role of practice and holds that one of the key tasks of ethics is to solve practical problems in concrete situations. It has certain similarities to utilitarianism and its focus on consequences but concentrates more on how morality is embedded in and relative to social and cultural contexts. Pragmatists tend to give more importance to habits than to conscious deliberation and understand morality as a habit that should be shaped in the right way. Postmodern ethics agrees with pragmatist ethics about the cultural relativity of morality. It rejects the idea that there are objective moral principles that apply universally to all cultures and traditions. It asserts that there is no one coherent ethical code since morality itself is irrational and humans are morally ambivalent beings. Postmodern ethics instead focuses on how moral demands arise in specific situations as one encounters other people. Ethical egoism is the view that people should act in their self-interest or that an action is morally right if the person acts for their own benefit. It differs from psychological egoism, which states that people actually follow their self-interest without claiming that they should do so. Ethical egoists may act in agreement with commonly accepted moral expectations and benefit other people, for example, by keeping promises, helping friends, and cooperating with others. However, they do so only as a means to promote their self-interest. Ethical egoism is often criticized as an immoral and contradictory position. Normative ethics has a central place in most religions. Key aspects of Jewish ethics are to follow the 613 commandments of God according to the Mitzvah duty found in the Torah and to take responsibility for societal welfare. Christian ethics puts less emphasis on following precise laws and teaches instead the practice of selfless love, such as the Great Commandment to "Love your neighbor as yourself". The Five Pillars of Islam constitute a basic framework of Muslim ethics and focus on the practice of faith, prayer, charity, fasting during Ramadan, and pilgrimage to Mecca. Buddhists emphasize the importance of compassion and loving-kindness towards all sentient entities. A similar outlook is found in Jainism, which has non-violence as its principal virtue. Duty is a central aspect of Hindu ethics and is about fulfilling social obligations, which may vary depending on a person's social class and stage of life. Confucianism places great emphasis on harmony in society and sees benevolence as a key virtue. Taoism extends the importance of living in harmony to the whole world and teaches that people should practice effortless action by following the natural flow of the universe. Indigenous belief systems, like Native American philosophy and the African Ubuntu philosophy, often emphasize the interconnectedness of all living beings and the environment while stressing the importance of living in harmony with nature. Metaethics Metaethics is the branch of ethics that examines the nature, foundations, and scope of moral judgments, concepts, and values. It is not interested in which actions are right but in what it means for an action to be right and whether moral judgments are objective and can be true at all. It further examines the meaning of morality and other moral terms. Metaethics is a metatheory that operates on a higher level of abstraction than normative ethics by investigating its underlying assumptions. Metaethical theories typically do not directly judge which normative ethical theories are correct. However, metaethical theories can still influence normative theories by examining their foundational principles. Metaethics overlaps with various branches of philosophy. On the level of ontology, it examines whether there are objective moral facts. Concerning semantics, it asks what the meaning of moral terms are and whether moral statements have a truth value. The epistemological side of metaethics discusses whether and how people can acquire moral knowledge. Metaethics overlaps with psychology because of its interest in how moral judgments motivate people to act. It also overlaps with anthropology since it aims to explain how cross-cultural differences affect moral assessments. Basic concepts Metaethics examines basic ethical concepts and their relations. Ethics is primarily concerned with normative statements about what ought to be the case, in contrast to descriptive statements, which are about what is the case. Duties and obligations express requirements of what people ought to do. Duties are sometimes defined as counterparts of the rights that always accompany them. According to this view, someone has a duty to benefit another person if this other person has the right to receive that benefit. Obligation and permission are contrasting terms that can be defined through each other: to be obligated to do something means that one is not permitted not to do it and to be permitted to do something means that one is not obligated not to do it. Some theorists define obligations in terms of values or what is good. When used in a general sense, good contrasts with bad. When describing people and their intentions, the term evil rather than bad is often employed. Obligations are used to assess the moral status of actions, motives, and character traits. An action is morally right if it is in tune with a person's obligations and morally wrong if it violates them. Supererogation is a special moral status that applies to cases in which the agent does more than is morally required of them. To be morally responsible for an action usually means that the person possesses and exercises certain capacities or some form of control. If a person is morally responsible then it is appropriate to respond to them in certain ways, for example, by praising or blaming them. Realism, relativism, and nihilism A major debate in metaethics is about the ontological status of morality, questioning whether ethical values and principles are real. It examines whether moral properties exist as objective features independent of the human mind and culture rather than as subjective constructs or expressions of personal preferences and cultural norms. Moral realists accept the claim that there are objective moral facts. This view implies that moral values are mind-independent aspects of reality and that there is an absolute fact about whether a given action is right or wrong. A consequence of this view is that moral requirements have the same ontological status as non-moral facts: it is an objective fact whether there is an obligation to keep a promise just as it is an objective fact whether a thing is rectangular. Moral realism is often associated with the claim that there are universal ethical principles that apply equally to everyone. It implies that if two people disagree about a moral evaluation then at least one of them is wrong. This observation is sometimes taken as an argument against moral realism since moral disagreement is widespread in most fields. Moral relativists reject the idea that morality is an objective feature of reality. They argue instead that moral principles are human inventions. This means that a behavior is not objectively right or wrong but only subjectively right or wrong relative to a certain standpoint. Moral standpoints may differ between persons, cultures, and historical periods. For example, moral statements like "Slavery is wrong" or "Suicide is permissible" may be true in one culture and false in another. Some moral relativists say that moral systems are constructed to serve certain goals such as social coordination. According to this view, different societies and different social groups within a society construct different moral systems based on their diverging purposes. Emotivism provides a different explanation, stating that morality arises from moral emotions, which are not the same for everyone. Moral nihilists deny the existence of moral facts. They reject the existence of both objective moral facts defended by moral realism and subjective moral facts defended by moral relativism. They believe that the basic assumptions underlying moral claims are misguided. Some moral nihilists conclude from this that anything is allowed. A slightly different view emphasizes that moral nihilism is not itself a moral position about what is allowed and prohibited but the rejection of any moral position. Moral nihilism, like moral relativism, recognizes that people judge actions as right or wrong from different perspectives. However, it disagrees that this practice involves morality and sees it as just one type of human behavior. Naturalism and non-naturalism A central disagreement among moral realists is between naturalism and non-naturalism. Naturalism states that moral properties are natural properties accessible to empirical observation. They are similar to the natural properties investigated by the natural sciences, like color and shape. Some moral naturalists hold that moral properties are a unique and basic type of natural property. Another view states that moral properties are real but not a fundamental part of reality and can be reduced to other natural properties, such as properties describing the causes of pleasure and pain. Non-naturalism argues that moral properties form part of reality and argues that moral features are not identical or reducible to natural properties. This view is usually motivated by the idea that moral properties are unique because they express what should be the case. Proponents of this position often emphasize this uniqueness by claiming that it is a fallacy to define ethics in terms of natural entities or to infer prescriptive from descriptive statements. Cognitivism and non-cognitivism The metaethical debate between cognitivism and non-cognitivism is about the meaning of moral statements and is a part of the study of semantics. According to cognitivism, moral statements like "Abortion is morally wrong" and "Going to war is never morally justified" are truth-apt, meaning that they all have a truth value: they are either true or false. Cognitivism claims that moral statements have a truth value but is not interested in which truth value they have. It is often seen as the default position since moral statements resemble other statements, like "Abortion is a medical procedure" or "Going to war is a political decision", which have a truth value. There is a close relation between the semantic theory of cognitivism and the ontological theory of moral realism. Moral realists assert that moral facts exist. This can be used to explain why moral statements are true or false: a statement is true if it is consistent with the facts and false otherwise. As a result, philosophers who accept one theory often accept the other as well. An exception is error theory, which combines cognitivism with moral nihilism by claiming that all moral statements are false because there are no moral facts. Non-cognitivism is the view that moral statements lack a truth value. According to this view, the statement "Murder is wrong" is neither true nor false. Some non-cognitivists claim that moral statements have no meaning at all. A different interpretation is that they have another type of meaning. Emotivism says that they articulate emotional attitudes. According to this view, the statement "Murder is wrong" expresses that the speaker has a negative moral attitude towards murder or disapproves of it. Prescriptivism, by contrast, understands moral statements as commands. According to this view, stating that "Murder is wrong" expresses a command like "Do not commit murder". Moral knowledge The epistemology of ethics studies whether or how one can know moral truths. Foundationalist views state that some moral beliefs are basic and do not require further justification. Ethical intuitionism is one such view that says that humans have a special cognitive faculty through which they can know right from wrong. Intuitionists often argue that general moral truths, like "Lying is wrong", are self-evident and that it is possible to know them without relying on empirical experience. A different foundationalist position focuses on particular observations rather than general intuitions. It says that if people are confronted with a concrete moral situation, they can perceive whether right or wrong conduct was involved. In contrast to foundationalists, coherentists say that there are no basic moral beliefs. They argue that beliefs form a complex network and mutually support and justify one another. According to this view, a moral belief can only amount to knowledge if it coheres with the rest of the beliefs in the network. Moral skeptics say that people are unable to distinguish between right and wrong behavior, thereby rejecting the idea that moral knowledge is possible. A common objection by critics of moral skepticism asserts that it leads to immoral behavior. Thought experiments are used as a method in ethics to decide between competing theories. They usually present an imagined situation involving an ethical dilemma and explore how people's intuitions of right and wrong change based on specific details in that situation. For example, in Philippa Foot's trolley problem, a person can flip a switch to redirect a trolley from one track to another, thereby sacrificing the life of one person to save five. This scenario explores how the difference between doing and allowing harm affects moral obligations. Another thought experiment, proposed by Judith Jarvis Thomson, examines the moral implications of abortion by imagining a situation in which a person gets connected without their consent to an ill violinist. In this scenario, the violinist dies if the connection is severed, similar to how a fetus dies in the case of abortion. The thought experiment explores whether it would be morally permissible to sever the connection within the next nine months. Moral motivation On the level of psychology, metaethics is interested in how moral beliefs and experiences affect behavior. According to motivational internalists, there is a direct link between moral judgments and action. This means that every judgment about what is right motivates the person to act accordingly. For example, Socrates defends a strong form of motivational internalism by holding that a person can only perform an evil deed if they are unaware that it is evil. Weaker forms of motivational internalism say that people can act against their own moral judgments, for example, because of the weakness of the will. Motivational externalists accept that people can judge an act to be morally required without feeling a reason to engage in it. This means that moral judgments do not always provide motivational force. A closely related question is whether moral judgments can provide motivation on their own or need to be accompanied by other mental states, such as a desire to act morally. Applied ethics Applied ethics, also known as practical ethics, is the branch of ethics and applied philosophy that examines concrete moral problems encountered in real-life situations. Unlike normative ethics, it is not concerned with discovering or justifying universal ethical principles. Instead, it studies how those principles can be applied to specific domains of practical life, what consequences they have in these fields, and whether additional domain-specific factors need to be considered. One of the main challenges of applied ethics is to breach the gap between abstract universal theories and their application to concrete situations. For example, an in-depth understanding of Kantianism or utilitarianism is usually not sufficient to decide how to analyze the moral implications of a medical procedure like abortion. One reason is that it may not be clear how the Kantian requirement of respecting everyone's personhood applies to a fetus or, from a utilitarian perspective, what the long-term consequences are in terms of the greatest good for the greatest number. This difficulty is particularly relevant to applied ethicists who employ a top-down methodology by starting from universal ethical principles and applying them to particular cases within a specific domain. A different approach is to use a bottom-up methodology, known as casuistry. This method does not start from universal principles but from moral intuitions about particular cases. It seeks to arrive at moral principles relevant to a specific domain, which may not be applicable to other domains. In either case, inquiry into applied ethics is often triggered by ethical dilemmas in which a person is subject to conflicting moral requirements. Applied ethics covers issues belonging to both the private sphere, like right conduct in the family and close relationships, and the public sphere, like moral problems posed by new technologies and duties toward future generations. Major branches include bioethics, business ethics, and professional ethics. There are many other branches, and their domains of inquiry often overlap. Bioethics Bioethics covers moral problems associated with living organisms and biological disciplines. A key problem in bioethics is how features such as consciousness, being able to feel pleasure and pain, rationality, and personhood affect the moral status of entities. These differences concern, for example, how to treat non-living entities like rocks and non-sentient entities like plants in contrast to animals, and whether humans have a different moral status than other animals. According to anthropocentrism, only humans have a basic moral status. This suggests that all other entities possess a derivative moral status only insofar as they impact human life. Sentientism, by contrast, extends an inherent moral status to all sentient beings. Further positions include biocentrism, which also covers non-sentient lifeforms, and ecocentrism, which states that all of nature has a basic moral status. Bioethics is relevant to various aspects of life and many professions. It covers a wide range of moral problems associated with topics like abortion, cloning, stem cell research, euthanasia, suicide, animal testing, intensive animal farming, nuclear waste, and air pollution. Bioethics can be divided into medical ethics, animal ethics, and environmental ethics based on whether the ethical problems relate to humans, other animals, or nature in general. Medical ethics is the oldest branch of bioethics. The Hippocratic Oath is one of the earliest texts to engage in medical ethics by establishes ethical guidelines for medical practitioners like a prohibition to harm the patient. Medical ethics often addresses issues related to the start and end of life. It examines the moral status of fetuses, for example, whether they are full-fledged persons and whether abortion is a form of murder. Ethical issues also arise about whether a person has the right to end their life in cases of terminal illness or chronic suffering and if doctors may help them do so. Other topics in medical ethics include medical confidentiality, informed consent, research on human beings, organ transplantation, and access to healthcare. Animal ethics examines how humans should treat other animals. This field often emphasizes the importance of animal welfare while arguing that humans should avoid or minimize the harm done to animals. There is wide agreement that it is wrong to torture animals for fun. The situation is more complicated in cases where harm is inflicted on animals as a side effect of the pursuit of human interests. This happens, for example, during factory farming, when using animals as food, and for research experiments on animals. A key topic in animal ethics is the formulation of animal rights. Animal rights theorists assert that animals have a certain moral status and that humans should respect this status when interacting with them. Examples of suggested animal rights include the right to life, the right to be free from unnecessary suffering, and the right to natural behavior in a suitable environment. Environmental ethics deals with moral problems relating to the natural environment including animals, plants, natural resources, and ecosystems. In its widest sense, it covers the whole cosmos. In the domain of agriculture, this concerns the circumstances under which the vegetation of an area may be cleared to use it for farming and the implications of planting genetically modified crops. On a wider scale, environmental ethics addresses the problem of global warming and people's responsibility on the individual and collective levels, including topics like climate justice and duties towards future generations. Environmental ethicists often promote sustainable practices and policies directed at protecting and conserving ecosystems and biodiversity. Business and professional ethics Business ethics examines the moral implications of business conduct and how ethical principles apply to corporations and organizations. A key topic is corporate social responsibility, which is the responsibility of corporations to act in a manner that benefits society at large. Corporate social responsibility is a complex issue since many stakeholders are directly and indirectly involved in corporate decisions, such as the CEO, the board of directors, and the shareholders. A closely related topic is the question of whether corporations themselves, and not just their stakeholders, have moral agency. Business ethics further examines the role of honesty and fairness in business practices as well as the moral implications of bribery, conflict of interest, protection of investors and consumers, worker's rights, ethical leadership, and corporate philanthropy. Professional ethics is a closely related field that studies ethical principles applying to members of a specific profession, like engineers, medical doctors, lawyers, and teachers. It is a diverse field since different professions often have different responsibilities. Principles applying to many professions include that the professional has the required expertise for the intended work and that they have personal integrity and are trustworthy. Further principles are to serve the interest of their target group, follow client confidentiality, and respect and uphold the client's rights, such as informed consent. More precise requirements often vary between professions. A cornerstone of engineering ethics is to protect public safety, health, and well-being. Legal ethics emphasizes the importance of respect for justice, personal integrity, and confidentiality. Key factors in journalism ethics include accuracy, truthfulness, independence, and impartiality as well as proper attribution to avoid plagiarism. Other subfields Many other fields of applied ethics are discussed in the academic literature. Communication ethics covers moral principles of communicative conduct. Two key issues in it are freedom of speech and speech responsibility. Freedom of speech concerns the ability to articulate one's opinions and ideas without the threats of punishment and censorship. Speech responsibility is about being accountable for the consequences of communicative action and inaction. A closely related field is information ethics, which focuses on the moral implications of creating, controlling, disseminating, and using information. The ethics of technology examines the moral issues associated with the creation and use of any artifact, from simple spears to high-tech computers and nanotechnology. Central topics in the ethics of technology include the risks associated with creating new technologies, their responsible use, and questions about human enhancement through technological means, such as performance-enhancing drugs and genetic enhancement. Important subfields include computer ethics, ethics of artificial intelligence, machine ethics, ethics of nanotechnology, and nuclear ethics. The ethics of war investigates moral problems of war and violent conflicts. According to just war theory, waging war is morally justified if it fulfills certain conditions. These conditions are commonly divided into requirements concerning the cause to initiate violent activities, such as self-defense, and the way those violent activities are conducted, such as avoiding excessive harm to civilians in the pursuit of legitimate military targets. Military ethics is a closely related field that is interested in the conduct of military personnel. It governs questions of the circumstances under which they are permitted to kill enemies, destroy infrastructure, and put the lives of their own troops at risk. Additional topics are the recruitment, training, and discharge of military personnel. Further fields of applied ethics include political ethics, which examines the moral dimensions of political decisions, educational ethics, which covers ethical issues related to proper teaching practices, and sexual ethics, which addresses the moral implications of sexual behavior. Related fields Value theory Value theory, also called axiology, is the philosophical study of value. It examines the nature and types of value. A central distinction is between intrinsic and instrumental value. An entity has intrinsic value if it is good in itself or good for its own sake. An entity has instrumental value if it is valuable as a means to something else, for example, by causing something that has intrinsic value. Further topics include what kinds of things have value and how valuable they are. For instance, axiological hedonists say that pleasure is the only source of intrinsic value and that the magnitude of value corresponds to the degree of pleasure. Axiological pluralists, by contrast, hold that there are different sources of intrinsic value, such as happiness, knowledge, and beauty. There are disagreements about the exact relation between value theory and ethics. Some philosophers characterize value theory as a subdiscipline of ethics while others see value theory as the broader term that encompasses other fields besides ethics, such as aesthetics and political philosophy. A different characterization sees the two disciplines as overlapping but distinct fields. The term axiological ethics is sometimes used for the discipline studying this overlap, that is, the part of ethics that studies values. The two disciplines are sometimes distinguished based on their focus: ethics is about moral behavior or what is right while value theory is about value or what is good. Some ethical theories, like consequentialism, stand very close to value theory by defining what is right in terms of what is good. But this is not true for ethics in general and deontological theories tend to reject the idea that what is good can be used to define what is right. Moral psychology Moral psychology explores the psychological foundations and processes involved in moral behavior. It is an empirical science that studies how humans think and act in moral contexts. It is interested in how moral reasoning and judgments take place, how moral character forms, what sensitivity people have to moral evaluations, and how people attribute and react to moral responsibility. One of its key topics is moral development or the question of how morality develops on a psychological level from infancy to adulthood. According to Lawrence Kohlberg, children go through different stages of moral development as they understand moral principles first as fixed rules governing reward and punishment, then as conventional social norms, and later as abstract principles of what is objectively right across societies. A closely related question is whether and how people can be taught to act morally. Evolutionary ethics, a closely related field, explores how evolutionary processes have shaped ethics. One of its key ideas is that natural selection is responsible for moral behavior and moral sensitivity. It interprets morality as an adaptation to evolutionary pressure that augments fitness by offering a selective advantage. Altruism, for example, can provide benefits to group survival by improving cooperation. Some theorists, like Mark Rowlands, argue that morality is not limited to humans, meaning that some non-human animals act based on moral emotions. Others explore evolutionary precursors to morality in non-human animals. Descriptive ethics Descriptive ethics, also called comparative ethics, studies existing moral codes, practices, and beliefs. It investigates and compares moral phenomena in different societies and different groups within a society. It aims to provide a value-neutral and empirical description without judging or justifying which practices are objectively right. For instance, the question of how nurses think about the ethical implications of abortion belongs to descriptive ethics. Another example is descriptive business ethics, which describes ethical standards in the context of business, including common practices, official policies, and employee opinions. Descriptive ethics also has a historical dimension by exploring how moral practices and beliefs have changed over time. Descriptive ethics is a multidisciplinary field that is covered by disciplines such as anthropology, sociology, psychology, and history. Its empirical outlook contrasts with the philosophical inquiry into normative questions, such as which ethical principles are correct and how to justify them. History The history of ethics studies how moral philosophy has developed and evolved in the course of history. It has its origin in ancient civilizations. In ancient Egypt, the concept of Maat was used as an ethical principle to guide behavior and maintain order by emphasizing the importance of truth, balance, and harmony. In ancient India starting in the 2nd millennium BCE, the Vedas and later Upanishads were composed as the foundational texts of Hindu philosophy and discussed the role of duty and the consequences of one's actions. Buddhist ethics originated in ancient India between the sixth and the fifth centuries BCE and advocated compassion, non-violence, and the pursuit of enlightenment. Ancient China in the 6th century BCE saw the emergence of Confucianism, which focuses on moral conduct and self-cultivation by acting in agreement with virtues, and Daoism, which teaches that human behavior should be in harmony with the natural order of the universe. In ancient Greece, Socrates emphasized the importance of inquiry into what a good life is by critically questioning established ideas and exploring concepts like virtue, justice, courage, and wisdom. According to Plato, to lead a good life means that the different parts of the soul are in harmony with each other. For Aristotle (384–322 BCE), a good life is associated with being happy by cultivating virtues and flourishing. Starting in the 4th century BCE, the close relation between right action and happiness was also explored by the Hellenistic schools of Epicureanism, which recommended a simple lifestyle without indulging in sensory pleasures, and Stoicism, which advocated living in tune with reason and virtue while practicing self-mastery and becoming immune to disturbing emotions. Ethical thought in the medieval period was strongly influenced by religious teachings. Christian philosophers interpreted moral principles as divine commands originating from God. Thomas Aquinas (1224–1274 CE) developed natural law ethics by claiming that ethical behavior consists in following the laws and order of nature, which he believed were created by God. In the Islamic world, philosophers like Al-Farabi and Avicenna (980–1037 CE) synthesized ancient Greek philosophy with the ethical teachings of Islam while emphasizing the harmony between reason and faith. In medieval India, Hindu philosophers like Adi Shankara and Ramanuja (1017–1137 CE) saw the practice of spirituality to attain liberation as the highest goal of human behavior. Moral philosophy in the modern period was characterized by a shift toward a secular approach to ethics. Thomas Hobbes (1588–1679) identified self-interest as the primary drive of humans. He concluded that it would lead to "a war of every man against every man" unless a social contract is established to avoid this outcome. David Hume (1711–1776) thought that only moral sentiments, like empathy, can motivate ethical actions while he saw reason not as a motivating factor but only as what anticipates the consequences of possible actions. Immanuel Kant (1724–1804), by contrast, saw reason as the source of morality. He formulated a deontological theory, according to which the ethical value of actions depends on their conformity with moral laws independent of their outcome. These laws take the form of categorical imperatives, which are universal requirements that apply to every situation. Georg Wilhelm Friedrich Hegel (1770–1831) saw Kant's categorical imperative on its own as an empty formalism and emphasized the role of social institutions in providing concrete content to moral duties. According to the Christian philosophy of Søren Kierkegaard (1813–1855), the demands of ethical duties are sometimes suspended when doing God's will. Friedrich Nietzsche (1844–1900) formulated criticisms of both Christian and Kantian morality. Another influential development in this period was the formulation of utilitarianism by Jeremy Bentham (1748–1832) and John Stuart Mill (1806–1873). According to the utilitarian doctrine, actions should promote happiness while reducing suffering and the right action is the one that produces the greatest good for the greatest number of people. An important development in 20th-century ethics in analytic philosophy was the emergence of metaethics. Significant early contributions to this field were made by G. E. Moore (1873–1958), who argued that moral values are essentially different from other properties found in the natural world. R. M. Hare (1919–2002) followed this idea in formulating his prescriptivism, which states that moral statements are commands that, unlike regular judgments, are neither true nor false. J. L. Mackie (1917–1981) suggested that every moral statement is false since there are no moral facts. An influential argument for moral realism was made by Derek Parfit (1942–2017), who argued that morality concerns objective features of reality that give people reasons to act in one way or another. Bernard Williams (1929–2003) agreed with the close relation between reasons and ethics but defended a subjective view instead that sees reasons as internal mental states that may or may not reflect external reality. Another development in this period was the revival of ancient virtue ethics by philosophers like Philippa Foot (1920–2010). In the field of political philosophy, John Rawls (1921–2002) relied on Kantian ethics to analyze social justice as a form of fairness. In continental philosophy, phenomenologists such as Max Scheler (1874–1928) and Nicolai Hartmann (1882–1950) built ethical systems based on the claim that values have objective reality that can be investigated using the phenomenological method. Existentialists like Jean-Paul Sartre (1905–1980) and Simone de Beauvoir (1908–1986), by contrast, held that values are created by humans and explored the consequences of this view in relation to individual freedom, responsibility, and authenticity. This period also saw the emergence of feminist ethics, which questions traditional ethical assumptions associated with a male perspective and puts alternative concepts, like care, at the center.

Biological anthropology

Biological anthropology, also known as physical anthropology, is a social science discipline concerned with the biological and behavioral aspects of human beings, their extinct hominin ancestors, and related non-human primates, particularly from an evolutionary perspective. This subfield of anthropology systematically studies human beings from a biological perspective. Branches As a subfield of anthropology, biological anthropology itself is further divided into several branches. All branches are united in their common orientation and/or application of evolutionary theory to understanding human biology and behavior. Bioarchaeology is the study of past human cultures through examination of human remains recovered in an archaeological context. The examined human remains usually are limited to bones but may include preserved soft tissue. Researchers in bioarchaeology combine the skill sets of human osteology, paleopathology, and archaeology, and often consider the cultural and mortuary context of the remains. Evolutionary biology is the study of the evolutionary processes that produced the diversity of life on Earth, starting from a single common ancestor. These processes include natural selection, common descent, and speciation. Evolutionary psychology is the study of psychological structures from a modern evolutionary perspective. It seeks to identify which human psychological traits are evolved adaptations – that is, the functional products of natural selection or sexual selection in human evolution. Forensic anthropology is the application of the science of physical anthropology and human osteology in a legal setting, most often in criminal cases where the victim's remains are in the advanced stages of decomposition. Human behavioral ecology is the study of behavioral adaptations (foraging, reproduction, ontogeny) from the evolutionary and ecologic perspectives (see behavioral ecology). It focuses on human adaptive responses (physiological, developmental, genetic) to environmental stresses. Human biology is an interdisciplinary field of biology, biological anthropology, nutrition and medicine, which concerns international, population-level perspectives on health, evolution, anatomy, physiology, molecular biology, neuroscience, and genetics. Paleoanthropology is the study of fossil evidence for human evolution, mainly using remains from extinct hominin and other primate species to determine the morphological and behavioral changes in the human lineage, as well as the environment in which human evolution occurred. Paleopathology is the study of disease in antiquity. This study focuses not only on pathogenic conditions observable in bones or mummified soft tissue, but also on nutritional disorders, variation in stature or morphology of bones over time, evidence of physical trauma, or evidence of occupationally derived biomechanic stress. Primatology is the study of non-human primate behavior, morphology, and genetics. Primatologists use phylogenetic methods to infer which traits humans share with other primates and which are human-specific adaptations. History Origins Biological Anthropology looks different today from the way it did even twenty years ago. Even the name is relatively new, having been 'physical anthropology' for over a century, with some practitioners still applying that term. Biological anthropologists look back to the work of Charles Darwin as a major foundation for what they do today. However, if one traces the intellectual genealogy back to physical anthropology's beginnings—before the discovery of much of what we now know as the hominin fossil record—then the focus shifts to human biological variation. Some editors, see below, have rooted the field even deeper than formal science. Attempts to study and classify human beings as living organisms date back to ancient Greece. The Greek philosopher Plato ( 428– 347 BC) placed humans on the scala naturae, which included all things, from inanimate objects at the bottom to deities at the top. This became the main system through which scholars thought about nature for the next roughly 2,000 years. Plato's student Aristotle ( 384–322 BC) observed in his History of Animals that human beings are the only animals to walk upright and argued, in line with his teleological view of nature, that humans have buttocks and no tails in order to give them a soft place to sit when they are tired of standing. He explained regional variations in human features as the result of different climates. He also wrote about physiognomy, an idea derived from writings in the Hippocratic Corpus. Scientific physical anthropology began in the 17th to 18th centuries with the study of racial classification (Georgius Hornius, François Bernier, Carl Linnaeus, Johann Friedrich Blumenbach). The first prominent physical anthropologist, the German physician Johann Friedrich Blumenbach (1752–1840) of Göttingen, amassed a large collection of human skulls (Decas craniorum, published during 1790–1828), from which he argued for the division of humankind into five major races (termed Caucasian, Mongolian, Aethiopian, Malayan and American). In the 19th century, French physical anthropologists, led by Paul Broca (1824–1880), focused on craniometry while the German tradition, led by Rudolf Virchow (1821–1902), emphasized the influence of environment and disease upon the human body. In the 1830s and 40s, physical anthropology was prominent in the debate about slavery, with the scientific, monogenist works of the British abolitionist James Cowles Prichard (1786–1848) opposing those of the American polygenist Samuel George Morton (1799–1851). In the late 19th century, German-American anthropologist Franz Boas (1858–1942) strongly impacted biological anthropology by emphasizing the influence of culture and experience on the human form. His research showed that head shape was malleable to environmental and nutritional factors rather than a stable "racial" trait. However, scientific racism still persisted in biological anthropology, with prominent figures such as Earnest Hooton and Aleš Hrdlička promoting theories of racial superiority and a European origin of modern humans. "New physical anthropology" In 1951 Sherwood Washburn, a former student of Hooton, introduced a "new physical anthropology." He changed the focus from racial typology to concentrate upon the study of human evolution, moving away from classification towards evolutionary process. Anthropology expanded to include paleoanthropology and primatology. The 20th century also saw the modern synthesis in biology: the reconciling of Charles Darwin's theory of evolution and Gregor Mendel's research on heredity. Advances in the understanding of the molecular structure of DNA and the development of chronological dating methods opened doors to understanding human variation, both past and present, more accurately and in much greater detail.

Sustainable city

A sustainable city, eco-city, or green city is a city designed with consideration for the social, economic, and environmental impact (commonly referred to as the triple bottom line), as well as a resilient habitat for existing populations. This is done in a way that does not compromise the ability of future generations to experience the same. The UN Sustainable Development Goal 11 defines sustainable cities as those that are dedicated to achieving green sustainability, social sustainability and economic sustainability. In accordance with the UN Sustainable Development Goal 11, a sustainable city is defined as one that is dedicated to achieving green, social, and economic sustainability. They are committed to this objective by facilitating opportunities for all through a design that prioritizes inclusivity as well as maintaining a sustainable economic growth. Furthermore, the objective is to minimize the inputs of energy, water, and food, and to drastically reduce waste, as well as the outputs of heat, air pollution (including , methane, and water pollution). Richard Register, a visual artist, first coined the term ecocity in his 1987 book Ecocity Berkeley: Building Cities for a Healthy Future, where he offers innovative city planning solutions that would work anywhere. Other leading figures who envisioned sustainable cities are architect Paul F Downton, who later founded the company Ecopolis Pty Ltd, as well as authors Timothy Beatley and Steffen Lehmann, who have written extensively on the subject. The field of industrial ecology is sometimes used in planning these cities. The UN Environment Programme calls out that most cities today are struggling with environmental degradation, traffic congestion, inadequate urban infrastructure, in addition to a lack of basic services, such as water supply, sanitation, and waste management. A sustainable city should promote economic growth and meet the basic needs of its inhabitants, while creating sustainable living conditions for all. Ideally, a sustainable city is one that creates an enduring way of life across the four domains of ecology, economics, politics, and culture. The European Investment Bank is assisting cities in the development of long-term strategies in fields including renewable transportation, energy efficiency, sustainable housing, education, and health care. The European Investment Bank has spent more than €150 billion in bettering cities over the last eight years. Cities occupy just 3 percent of the Earth's land but account for 60 to 80 percent of energy consumption and at least 70 percent of carbon emissions. Thus, creating safe, resilient, and sustainable cities is one of the top priorities of the Sustainable Development Goals. The Adelaide City Council states that socially sustainable cities should be equitable, diverse, connected, democratic, and provide a good quality of life. Priorities of a sustainable city include the ability to feed itself with a sustainable reliance on the surrounding natural environment and the ability to power itself with renewable sources of energy, while creating the smallest conceivable ecological footprint and the lowest quantity of pollution achievable. All of this is to be accomplished by efficient land use, composting organic matter, recycling used materials, and/or converting waste-to-energy. The idea is that these contributions will lead to a decrease of the city's impact on climate change. Today, 55 percent of the world is estimated to be living in urban areas and the United Nations estimates that by the year 2050, that number will rise to 70 percent. By 2050, there may be nearly 2.5 more billion individuals living in urban cities, possibly making it more difficult to create more sustainable communities. These large communities provide both challenges and opportunities for environmentally-conscious developers. There are distinct advantages to further defining and working towards the goals of sustainable cities. Humans thrive in urban spaces that foster social connections. Richard Florida, an urban studies theorist, focuses on the social impact of sustainable cities and states that cities need more than a competitive business climate; they should promote a great people climate that appeals to individuals and families of all types. Because of this, a shift to denser urban living would provide an outlet for social interaction and conditions under which humans can prosper. These types of urban areas would also promote the use of public transit, walkability, and biking which would benefit citizens' health as well as benefiting the environment. Practical methods to create sustainable cities Different agricultural systems such as agricultural plots within the city (suburbs or centre). This reduces the distance food has to travel from field to fork. This may be done by either small-scale/private farming plots or through larger-scale agriculture (e.g. farmscrapers). Renewable energy sources, such as wind turbines, solar panels, or bio-gas created from sewage to reduce and manage pollution. Cities provide economies of scale that make such energy sources viable. Various methods to reduce the need for air conditioning (a massive energy demand), such as passive daytime radiative cooling applications, planting trees and lightening surface colors, natural ventilation systems, an increase in water features, and green spaces equaling at least 20% of the city's surface. These measures counter the "heat island effect" caused by an abundance of tarmac and asphalt, which can make urban areas several degrees warmer than surrounding rural areas—as much as six degrees Celsius during the evening. Improved public transport and an increase in pedestrianization to reduce car emissions. This requires a radically different approach to city planning, with integrated business, industrial, and residential zones. Roads may be designed to make driving difficult. Optimal building density to make public transport viable but avoid the creation of urban heat islands. Green roofs alter the surface energy balance and can help mitigate the urban heat island effect. Incorporating eco roofs or green roofs in your design will help with air quality, climate, and water runoff. Zero-emission transport Zero-energy building to reduce energy consumption and greenhouse gas emissions using renewable energy sources. Sustainable urban drainage systems or SUDS in addition to other systems to reduce and manage waste. Energy conservation systems/devices Xeriscaping – garden and landscape design for water conservation Sustainable transport, incorporates five elements: fuel economy, occupancy, electrification, pedal power, and urbanization. Circular economy to combat inefficient resource patterns and ensure a sustainable production and consumption roadmap. Increase of cycling infrastructure would increase cycling within cities and reduce the number of cars being driven and in turn reduce car emissions. This would also benefit the health of citizens as they would be able to get more exercise through cycling. Key performance indicators – development and operational management tool providing guidance and M&V for city administrators currently monitor and evaluate energy savings in various facilities. Sustainable Sites Initiative or SSI – voluntary national guidelines and performance benchmarks for sustainable land design, construction and maintenance practices. Key areas of focus are soil, vegetation, hydrology, materials, and human health and well-being. Sustainable cities are creating safe spaces for its inhabitants through various means, such as: Solutions to decrease urban sprawl, by seeking new ways of allowing people to live closer to the workspace. Since the workplace tends to be in the city, downtown, or urban center, they are seeking a way to increase density by changing the antiquated attitudes many suburbanites have towards inner-city areas. One of the new ways to achieve this is by solutions worked out by the Smart Growth Movement. Educating residents of cities about the importance and positive impacts of living in a more sustainable city. This is to boost the initiative to have sustainable developments and push people to live in a more sustainable and environmentally-friendly way. Policy and planning changes to meet the unmet demands for urban services (water, energy, transport). With regard to methods of emissions counting cities can be challenging as production of goods and services within their territory can be related either to domestic consumption or exports. Conversely the citizens also consume imported goods and services. To avoid double counting in any emissions calculation it should be made clear where the emissions are to be counted: at the site of production or consumption. This may be complicated given long production chains in a globalized economy. Moreover, the embodied energy and consequences of large-scale raw material extraction required for renewable energy systems and electric vehicle batteries is likely to represent its own complications – local emissions at the site of utilization are likely to be very small but life-cycle emissions can still be significant. Architecture Buildings provide the infrastructure for a functioning city and allow for many opportunities to demonstrate a commitment to sustainability. A commitment to sustainable architecture encompasses all phases of building including the planning, building, and restructuring. Sustainable Site Initiative is used by landscape architects, designers, engineers, architects, developers, policy-makers, and others to align land development and management with innovative sustainable design. Eco-industrial park The UNIDO (United Nation's Industrial Development Organization) defines eco-industrial park as a community of businesses located on a common property in which businesses seek to achieve enhanced environmental, economic, and social performance through collaboration in managing environmental and resource issues. This is an industrial symbiosis where companies gain an added benefit by physically exchanging materials, energy, water, and by-products, thus enabling sustainable development. This collaboration reduces environmental impact while simultaneously improves economic performance of the area. The components for building an eco-industrial park include natural systems, more efficient use of energy, and more efficient material and water flows. Industrial parks should be built to fit into their natural settings in order to reduce environmental impacts, which can be accomplished through plant design, landscaping, and choice of materials. For instance, there is an industrial park in Michigan built by Phoenix Designs that is made almost entirely from recycled materials. The landscaping of the building will include native trees, grasses, and flowers, and the landscaping design will also act as climate shelter for the facility. In choosing the materials for building an eco-industrial park, designers must consider the life-cycle analysis of each medium that goes into the building to assess their true impact on the environment and to ensure that they are using it from one plant to another, steam connections from firms to provide heating for homes in the area, and using renewable energy such as wind and solar power. In terms of material flows, the companies in an eco-industrial park may have common waste treatment facilities, a means for transporting by-products from one plant to another, or anchoring the park around resource recovery companies that are recruited to the location or started from scratch. To create more efficient water flows in industrial parks, the processed water from one plant can be reused by another plant and the park's infrastructure can include a way to collect and reuse stormwater runoff. Examples Recycled Park in Rotterdam, the Netherlands The Recycled Park in Rotterdam, the second-largest city in the Netherlands, is an initiative introduced by Recycled Island Foundation, a Netherlands-based organization focused on recycling littered waste via creating their iconic island-parks, among other sustainable projects. Rotterdam's Recycled Park is a cluster of floating, green hexagonal "islands" composed of reused litter. The group has utilized a system of passive litter traps to collect this litter from the Maas River. The park's location upon the Maas River reflects a circular process aimed at creating a more sustainable city. On the underside of the recycled park are materials that will support the growth of plants and wildlife indigenous to the area. This interest in growing the biodiversity of Rotterdam's natural elements is also reflected in other cities. Chicago's Urban Rivers organization is similarly trying to solve this issue by building and growing the Wild Mile of floating parks and forests along the Chicago River with the goal of revegetation. Both Urban Rivers' and Recycled Island Foundation's interest in improving the area's biodiversity reflects an interest in greening the built urbanism of the surrounding city. Rotterdam's Recycled Park may suggest a greater trend in creating floating structures in response to greater climate-change-motivated impacts. The Floating Farm in Rotterdam sustainably approaches food production and transport. Other floating structures include renewable energy-powered houseboats and luxury residences some 800 meters from the coast. The Dutch city of Amsterdam likewise boasts a neighbourhood of artificial, floating islands in the suburb of IJburg. The idea of expanding both commercial enterprise and residential developments onto the water is oftentimes reflective of the demand to limit land-usage in urban areas. This has various, wide-reaching environmental impacts: reducing the aggregation of the urban heat-island effect, the zoning efforts expended on engineering and regulating the floodplain (and potentially, the capacity of waste-water reservoirs), and reduce the demands of the automobility state. The Recycled Park is a holistic approach to limiting the expense of waste. The employment of greenery has air-purifying effects, to reduce pollution. Additionally, the modular, hexagonal design allows reconstruction of each "island"; this space thus also offers environmental sustainability, as well as an open space for community-growing and other social opportunities. Urban farming Urban farming is the process of growing and distributing food, as well as raising animals, in and around a city or in urban areas. According to the RUAF Foundation, urban farming is different from rural agriculture because it is integrated into the urban economic and ecological system: urban agriculture is embedded in and interacting with the urban ecosystem. Such linkages include the use of urban residents as the key workers, use of typical urban resources (such as utilizing organic waste as compost or urban wastewater for irrigation), direct links with urban consumers, direct impacts on urban ecology (positive and negative), being part of the urban food system, competing for land with other urban functions, being influenced by urban policies and plans. One motivation for urban agriculture in sustainable cities includes saving energy that would be used in food transportation. Urban farming infrastructure can include common areas for community gardens or farms, as well as common areas for farmers markets in which the food items grown within the city can be sold to the residents of the urban system. Tiny forests or miniature forests is a new concept where many trees are grown on a small patch of land. These forests are said to grow 10x faster and 30x denser with 100x biodiversity than larger forests. Additionally, they are 100% organic. The ratio of shrub layer, sub-tree layer, tree layer, and canopy layer of the miniature forest along with the percentage of each tree species are planned and fixed before planting so as to promote biodiversity. New Urbanism The most clearly defined form of walkable urbanism is known as the Charter of New Urbanism. It is an approach for successfully reducing environmental impacts by altering the built environment to create and preserve smart cities that support sustainable transport. Residents in compact urban neighbourhoods drive fewer miles and have significantly lower environmental impacts across a range of measures, compared with those living in sprawling suburbs. The concept of circular flow land use management has also been introduced in Europe to promote sustainable land use patterns that strive for compact cities and a reduction of greenfield land taken by urban sprawl. Sustainable architecture, a recent movement of New Classical Architecture, promotes a sustainable approach towards construction that appreciates and develops smart growth, walkability, vernacular tradition, and classical design. This in contrast to modernist and globally uniform architecture and opposes solitary housing estates and suburban sprawl. Both trends started in the 1980s. Individual buildings (LEED) The Leadership in Energy and Environmental Design (LEED) Green Building Rating System encourages and accelerates global adoption of sustainable green building and development practices through the creation and implementation of universally understood and accepted tools and performance criteria. LEED, or Leadership in Energy and Environmental Design, is an internationally recognized green building certification system. LEED recognizes whole building sustainable design by identifying key areas of excellence including: Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, Indoor Environmental Quality, Locations & Linkages, Awareness and Education, Innovation in Design, Regional Priority. In order for a building to become LEED certified sustainability needs to be prioritized in design, construction, and use. One example of sustainable design would be including a certified wood like bamboo. Bamboo is fast growing and has an incredible replacement rate after being harvested. By far the most credits are rewarded for optimizing energy performance. This promotes innovative thinking about alternative forms of energy and encourages increased efficiency. A new district in Helsinki, Finland is being made almost entirely using timber. This timber is a form of a Laminated Veneer Lumbar (LVL) that has high standards of fire resistance. The idea is that wood construction has a much smaller footprint than concrete and steel construction and thus, this project is going to take Finland's timber architecture to new heights of sustainability. Sustainable Sites Initiative (SSI) Sustainable Sites Initiative, a combined effort of the American Society of Landscape Architects, The Lady Bird Johnson Wildflower Center at The University of Texas at Austin, and the United States Botanic Garden, is a voluntary national guideline and performance benchmark for sustainable land design, construction and maintenance practices. The building principles of SSI are to design with nature and culture, use a decision-making hierarchy of preservation, conservation, and regeneration, use a system thinking approach, provide regenerative systems, support a living process, use a collaborative and ethical approach, maintain integrity in leadership and research, and finally foster environmental stewardship. All of these help promote solutions to common environmental issues such as greenhouse gases, urban climate issues, water pollution and waste, energy consumption, and health and wellbeing of site users. The main focus is hydrology, soils, vegetation, materials, and human health and well-being. In SSI, the main goal for hydrology in sites is to protect and restore existing hydrologic functions. To design storm water features to be accessible to site users, and manage and clean water on site. For site design of soil and vegetation many steps can be done during the construction process to help minimize the urban heat island effects, and minimize the building heating requirements by using plants. Regenerative Architecture Regenerative architecture is usually applied to remediate brownfield sites. Still, it can encompass a broader mindset to help an ecosystem, region, or site recover during the lifetime of a structure, during construction and operation. Regenerative architecture tends to require buildings to self-sustain themselves, including generating their sources of power and water. However, it is essential to acknowledge that a structure should only consume what it can recover while also facilitating an area for regeneration. This design mindset differs from the term sustainability as it seeks to contribute the most to an environment instead of reducing the most harm (an efficiency paradigm). This calls for a more holistic engagement with a singular site rather than broad assumptions about a general ecology. Regenerative architecture also extends beyond ecological concerns and can encompass improving social value. Since brownfields typically reside near or within human settlements, regenerative design can enhance human well-being as a site for engagement while also considering ecological needs. It is a way of synchronizing stewardship towards recovery and resilience through design while also considering the social and economic dimensions of these problems. Regenerative "refers to a process that repairs, recreates or revitalizes its own sources of energy or air, water or any other matter." For design, this means considering the impacts of products (or by-products) from Cradle-to-Grave and the cycle of resource consumption throughout these processes. A positive-impact building is a regenerative one. Examples include producing "more energy & treated water that the building consumes . . . the ability to provide habitat for lost wildlife and plant species, restore the natural hydrology by recharging the groundwater system, compost waste, and create opportunities for urban agriculture. Since these designs are capable of creating sustenance, they can be considered more economically viable, less dependable and more resilient. Converting unused industrial spaces into accessible green parks is a minor change in achieving regeneration, like the Phra Pok Klao Sky Park (a green park in the congested city of Bangkok), and The New York High Line. The Regenerative Paradigm The Anthropocene era encompasses the detrimental effects on pollution, biodiversity and climate that humans have created. In the building sector, structures have contributed to "40% of carbon emission, 14% of water consumption and 60% of waste production worldwide" in 2006. The term sustainability, largely publicized in the 1987 Bruntland Report, was a vital yardstick for institutions and governments to acknowledge the impact humans have made and generated a stream of thought where ecosystems became considerations in national agendas. The design lexicon has expanded over time "from issues of ecology, habitat, energy or pollution to address waste, lifecycle, community, sustainability and climate change" with notions of "organic or natural design . . . replaced by green, environmental, sustainable or resilient building." Still, the definition where sustainable development "meets the needs of the present without compromising the ability of future generations to meet their own needs" gears towards harm reduction, but offers enough flexibility for regions to develop their own specific guidelines. The 2013 Intergovernmental Panel on Climate Change (IPCC) report made the scientific and public community aware that the sustainable efficiency paradigm is leading towards a degenerative cycle. The Anthropocene era calls for action leading toward regeneration to reverse the impacts humans have caused instead of minimizing harm and maximizing efficiency. Since regenerative architecture seeks to restore an ecological site, it acknowledges that recovery and remediation are ongoing. Indigenous peoples and their methods of vernacular architecture have achieved similar perspectives in material sourcing as regenerative architecture, and the mindset of Regenerative Architecture includes bridging the human-nature paradox for the scope, complexity and diversity of needs for modern structures. Principles Regenerative Architecture can implement various standards like Life Cycle Assessments and Building Environmental Assessments (like LEED); however, regeneration is an ongoing activity, so it becomes contingent on ecological results. Regenerative architecture can use existing standards and principles to situate regeneration in a contemporary sustainability context, but it should extend beyond these frameworks to quantify various ecological impacts during the life-time of a building. Sustainability manifests in various forms of standardization and testing, creating frameworks such as Lifecycle Analysis (LCA) to assess the entire life-end-cycle of materials, to industry-specific systems like Building Environmental Assessments (BEAs) that consider broader areas of building and living performance to simplify integration within industry. BEAs reflect specific comprehensive (often esoteric) LCA principles through a simplified credit-weighing scale encompassing building environments and living performance. These areas apply more directly to architecture and are more accessible to decision-makers. These frameworks are very helpful in the design and construction phase, and regenerative frameworks can help extend these concepts towards future ecological resilience and evolution. Considerations include the safety and accountability of material sourcing, the reusability of the materials, renewable energy and carbon management, water impact, and social fairness. Eco-cities Eco-cities are rooted in various urban planning traditions, including the early garden city movement initiated by Ebenezer Howard. These early efforts sought self-contained, green, and interconnected communities. In the latter 20th century, a broader understanding of ecological systems prompted the need for cities to address their ecological impact both locally and globally. Concepts like "urban metabolism" and McHarg's ecological site planning emerged. The term "ecocity" was coined by Richard Register in the 1980s during the rise of sustainability concerns, as outlined in the Brundtland Commission Report. Sustainability in urban planning focuses on inter-generational equity, environmental protection, and more. In the 2000s, resilience became a key perspective, highlighting the importance of ecological and social resilience in cities facing climate change challenges. Transportation As major focus of the sustainable cities, sustainable transportation attempts to reduce a city's reliance and use of greenhouse emitting gases by utilizing eco-friendly urban planning, low environmental impact vehicles, and residential proximity to create an urban center that has greater environmental responsibility and social equity. Poor transportation systems lead to traffic jams and high levels of pollution. Due to the significant impact that transportation services have on a city's energy consumption, the last decade has seen an increasing emphasis on sustainable transportation by developmental experts. Currently, transportation systems account for nearly a quarter of the world's energy consumption and carbon dioxide emission. In order to reduce the environmental impact caused by transportation in metropolitan areas, sustainable transportation has three widely agreed-upon pillars that it utilizes to create more healthy and productive urban centers. The Carbon Trust states that there are three main ways cities can innovate to make transport more sustainable without increasing journey times – better land use planning, modal shift to encourage people to choose more efficient forms of transport, and making existing transport modes more efficient. Car free city The concept of car free cities or a city with large pedestrian areas is often part of the design of a sustainable city. A large part of the carbon footprint of a city is generated by cars so the car free concept is often considered an integral part of the design of a sustainable city. Large parts of London city are to be made car-free to allow people to walk and cycle safely following the COVID-19 lockdown. Similarly, 47 miles of bike lanes are planned to be opened in Bogotá, Colombia in addition to the existing 75-mile network of streets that was recently made to be traffic-free all week. New urbanism frees residents of Masdar City, UAE from automobiles and makes possible walkable and sustainable communities by integrating daily facilities such as plazas and sidewalks into the neighborhoods. Public transit systems like the Group Rapid Transit and the Metro provide direct access to wide areas of Masdar, as well as Abu Dhabi’s CBD, and other parts of the city. The COVID-19 pandemic gave birth to proposals for radical change in the organisation of the city, such as the Manifesto for the Reorganisation of the city after COVID19, published in Barcelona by architecture and urban theorist Massimo Paolini and signed by 160 academics and 300 architects, being the elimination of the car one of the key elements. Emphasis on proximity Created by eco-friendly urban planning, the concept of urban proximity is an essential element of current and future sustainable transportation systems. This requires that cities be built and added onto with appropriate population and landmark density so that destinations are reached with reduced time in transit. This reduced time in transit allows for reduced fuel expenditure and also opens the door to alternative means of transportation such as bike riding and walking. Furthermore, close proximity of residents and major landmarks allows for the creation of efficient public transportation by eliminating long sprawled out routes and reducing commute time. This in turn decreases the social cost to residents who choose to live in these cities by allowing them more time with families and friends instead by eliminating part of their commute time. Melbourne is leading the way in creating the 20-minute neighbourhood where biking, walking or using public transport can get you to work, shops or a government agency within 20 minutes. Paris is experimenting with a similar concept in the Rue de Rivoli area where travel time for any destination is capped at 15 minutes. Diversity in modes of transportation Sustainable transportation emphasizes the use of a diversity of fuel-efficient transportation vehicles in order to reduce greenhouse emissions and diversity fuel demand. Due to the increasingly expensive and volatile cost of energy, this strategy has become very important because it allows a way for city residents to be less susceptible to varying highs and lows in various energy prices. Among the different modes of transportation, the use alternative energy cars and widespread installation of refueling stations has gained increasing importance, while the creation of centralized bike and walking paths remains a staple of the sustainable transportation movement. Tesla is one of the pioneers in creating electric vehicles, which is said to reduce footprints of cars. More companies globally are developing their own versions of electric cars and public transport to promote sustainable transportation. Access to transportation In order to maintain the aspect of social responsibility inherent within the concept of sustainable cities, implementing sustainable transportation must include access to transportation by all levels of society. Due to the fact that car and fuel cost are often too expensive for lower-income urban residents, completing this aspect often revolves around efficient and accessible public transportation. Social inclusion is a key goal of the United Nations Sustainable Development Goal 11 – Sustainable Cities and Communities. In order to make public transportation more accessible, the cost of rides must be affordable and stations must be located no more than walking distance in each part of the city. As studies have shown, this accessibility creates a great increase in social and productive opportunity for city residents. By allowing lower-income residents cheap and available transportation, it allows for individuals to seek employment opportunities all over the urban center rather than simply the area in which they live. This in turn reduces unemployment and a number of associated social problems such as crime, drug use, and violence. Smart transportation In this age of smart cities, many smart solutions are being experimented with to regulate transportation and make public transport more efficient. Israel is reinventing commute by engaging in a public-private partnership that uses algorithms to route public transport according to needs. Using the concept of mobility as a service (MaaS), the people of Israel are encouraged to put in their destination on a mobile application; this data is then processed by the application to reroute transportation according to demands and options of different modes of transportation are suggested to the commuters to choose from. This decreases futile trips and helps the government regulate the number of people in a train or a bus at a time, especially useful in times of a pandemic like the COVID-19 pandemic. Urban strategic planning Although there is not an international policy regarding sustainable cities and there are not established international standards, the organization United Cities and Local Governments (UCLG) is working to establish universal urban strategic guidelines. The UCLG is a democratic and decentralized structure that operates in Africa, Eurasia, Latin America, North America, Middle East, West Asian and a Metropolitan section work to promote a more sustainable society. The 60 members of the UCLG committee evaluate urban development strategies and debate these experiences to make the best recommendations. Additionally, the UCLG accounts for differences in regional and national context. All the organizations are making a great effort to promote this concept by media and Internet, and in conferences and workshops. An International conference was held in Italy at Università del Salento and Università degli Studi della Basilicata, called 'Green Urbanism', from 12 to 14 October 2016. Development Recently, local and national governments and regional bodies such as the European Union have recognized the need for a holistic understanding of urban planning. This is instrumental to establishing an international policy that focuses on cities challenges and the role of the local authorities responses. The sustainable development of urban areas is crucial since more than 56% of the world's population lives in cities. Cities are in the lead of climate action, while being responsible for an estimated 75% of the world's carbon emissions. Generally, in terms of urban planning, the responsibility of local governments are limited to land use and infrastructure provision excluding inclusive urban development strategies. The advantages of urban strategic planning include an increase in governance and cooperation that aids local governments in establishing performance based-management, clearly identifying the challenges facing local community and more effectively responding on a local level rather than national level, and improves institutional responses and local decision making. Additionally, it increases dialogue between stakeholders and develops consensus-based solutions, establishing continuity between sustainability plans and change in local government; it places environmental issues as the priority for the sustainable development of cities and serves as a platform to develop concepts and new models of housing, energy and mobility. Obstacles The City Development Strategies (CDS) addresses new challenges and provides space for innovative policies that involves all stakeholders. The inequality in spatial development and socio-economic classes paired with concerns of poverty reduction and climate change are factors in achieving global sustainable cities, as highlighted by the United Nations Sustainable Development Goal 11. According to the UCLG there are differences between regional and national conditions, framework and practice that are overcome in the international commitment to communication and negotiation with other governments, communities and the private sector to continue to develop through innovative and participatory approaches in strategic decisions, building consensus and monitoring performance management and raising investment. Social factors of sustainable cities According to the United Nations Development Programme (UNDP), over half of the world's population is concentrated in cities, a proportion which is expected to rise to two-thirds by 2050. United Cities and Local Governments has specifically identified 13 global challenges to establishing sustainable cities: demographic change and migration, globalisation of the job market, poverty and unmet Millennium Development Goals, segregation, spatial patterns and urban growth, metropolisation and the rise of urban regions, more political power for local authorities, new actors for developing a city and providing services, decline in public funding for development, the environment and climate change, new and accessible building technologies, preparing for uncertainty and limits of growth and global communications and partnerships. Social equity Gender Gender associates an individual with a set of traits and behaviors that are construed to be female and/or male by society. Gender is a key part of a person's identity, which can influence their experiences and opportunities as they navigate through life. This is no different for how gender impacts how they navigate through the built environment. Men and women experience the built environment differently. For over two decades, professionals in urban planning have called for the routine consideration of gender relations and gendered experiences in the urban design process. Specifically, city planners emphasize the need to account for systemic differences in people's lived experiences by gender, when designing built environments that are safe and equitable. This applies to the development of climate resilient cities. Women represent 80% of people who've been displaced by the climate crisis. Women are more vulnerable to the impacts of climate change because of the roles they are socially assigned by gender. For instance, women are primarily responsible for food provision in the household. Unprecedented patterns in the frequency and magnitude of floods and droughts – due to climate change – directly impact the caregiving responsibilities of many women, causing them to disproportionately suffer from the consequences of these natural disasters. The inequitable distribution of the burden of climate change by gender is unjust and can be addressed in the design of sustainable cities. Achieving gender equality is not only ethically important but economically smart, since supporting female development benefits economic growth. Moreover, it's socially and economically relevant to design sustainable cities not only for women, but by women. Notable women spearheading the sustainable city movement include mayors Anne Hidalgo, Ada Colau Ballano, Claudia Lopez, Yvonne Aki-Sawyerr, Muriel Bowser, Patricia de Lille, Helen Fernandez, and Clover Moore. Other female leaders include Christina Figueres, Patricia Espinosa, Laurence Tubiana, and Hakima El Haite. Race and Income Mobility or the ability to move/go places is essential to daily life. Our mobility is primarily determined by the transportation infrastructure that surrounds us. Throughout US history, mobility and right to place have been regulated through codified social rules of who can go where, and how. Many of these rules were drawn along racial/ethnic and nationalistic lines. Discriminatory housing and transit policies, like red lining, have compounded the oppressive living conditions marginalized racial groups have been subjected to centuries, and have limited the socioeconomic opportunities of future generations. The legacies of these discriminatory policies are responsible for many environmental injustices we see today. Environmental injustice refers to the unequal distribution of risk to environmental threats, with vulnerable populations – e.g., people of low- and middle-income (LMI) and people of color (POC) – experiencing the greatest exposure and least protection. Environmental injustice is pervasive and manifests in many ways, from contaminated drinking water to mold-infested housing stock. One example of environmental injustice is the varying burden of heat exposure on different racial and socioeconomic groups. Urban areas often experience higher surface temperatures than less developed regions because the concentrated impermeable surfaces are good at absorbing heat, creating the “heat-island” effect mentioned earlier. The risk of adverse health effects caused by the heat island effect is and will be compounded by the increasing frequency in heat waves due to the climate crisis. This threat is quite dangerous for vulnerable populations – including infants and the elderly – who lack access to air conditioning and/or tree coverage to cool down. This limited adaptive capacity to urban heat is concentrated in LMI and historically segregated neighborhoods. Specifically, neighborhoods in cities that were historically targeted by redlining and divestment experience higher average land surface temperatures than surrounding areas. These differences in surface temperatures embody the legacy of discriminatory housing policies in the US, and highlight how historic urban planning practices will interact with the effects of the climate crisis. We must create the sustainable cities of the future with these historic practices in mind. The heat island effect also exacerbates the impacts of another form of environmental injustice that disproportionately affects minority and low-income groups: air pollution. Urban infrastructure projects that produce environmental toxins – like industrial plants and highways – are frequently built near or in LMI and POC communities because of favorable zoning codes, cheaper land prices, and less political backlash. This is not because residents don't care, but because they often lack the time, resources, and connections necessary to prevent such construction. In turn, pollutant-producing operations disproportionately impact LMI and POC communities, harming the health outcomes of these groups. A study by the University of Minnesota found that if nitrogen dioxide levels (NO2 – a product of the combustion of fossil fuels) in non-white communities were reduced to equal those in white communities, there would be around 7,000 fewer deaths from heart disease per year. This mortality disparity highlights the health impacts of discriminatory zoning and urban planning policies, which disproportionately expose LIM and POC communities to air pollution. The disparity also shows how much we have to gain from sustainable transportation reform which eliminates combustion-engine vehicles. The inequitable breakdown of exposure to environmental risks by race and income reinforces the understanding that the climate crisis is a social issue, and that environmental justice depends upon racial justice. There is no one right way to address these issues. Proposed solutions include eliminating single-family zoning, pricing a minimum proportions of housing units for LMI households, and requiring community engagement in future urban planning projects. To select the best combination of solutions to create sustainable cities tailored to their environments, each city must be designed for all community members, by all community members. Leaders in the environmental justice movement include Robert Bullard, Benjamin Chavis, Peggy Shepard, Kandi Moseett-White, Mustafa Santiago Ali, Jamie Margolin, Elizabeth Yeampierre, LeeAnne Walters, and Dana Johnson. Examples Australia Adelaide Urban forests In Adelaide, South Australia (a city of 1.3 million people) Premier Mike Rann (2002 to 2011) launched an urban forest initiative in 2003 to plant 3 million native trees and shrubs by 2014 on 300 project sites across the metro area. The projects range from large habitat restoration projects to local biodiversity projects. Thousands of Adelaide citizens have participated in community planting days. Sites include parks, reserves, transport corridors, schools, water courses and coastline. Only trees native to the local area are planted to ensure genetic integrity. Premier Rann said the project aimed to beautify and cool the city and make it more liveable; improve air and water quality and reduce Adelaide's greenhouse gas emissions by 600,000 tonnes of a year. He said it was also about creating and conserving habitat for wildlife and preventing species loss. Solar power The Rann government also launched an initiative for Adelaide to lead Australia in the take-up of solar power. In addition to Australia's first 'feed-in' tariff to stimulate the purchase of solar panels for domestic roofs, the government committed millions of dollars to place arrays of solar panels on the roofs of public buildings such as the museum, art gallery, Parliament, Adelaide Airport, 200 schools and Australia's biggest rooftop array on the roof of Adelaide Showgrounds' convention hall which was registered as a power station. Wind power South Australia went from zero wind power in 2002 to wind power making up 26% of its electricity generation by October 2011. In the five years preceding 2011 there was a 15% drop in emissions, despite strong economic growth. Waste recycling For Adelaide the South Australian government also embraced a Zero Waste recycling strategy, achieving a recycling rate of nearly 80% by 2011 with 4.3 million tonnes of materials diverted from landfill to recycling. On a per capita basis, this was the best result in Australia, the equivalent of preventing more than a million tonnes of entering the atmosphere. In the 1970s container-deposit legislation was introduced. Consumers are paid a 10 cent rebate on each bottle, can, or container they return to recycling. In 2009 non-reusable plastic bags used in supermarket checkouts were banned by the Rann Government, preventing 400 million plastic bags per year entering the litter stream. In 2010 Zero Waste SA was commended by a UN Habitat Report entitled 'Solid Waste Management in the World Cities'. Melbourne City of Merri-bek. The City of Merri-bek in Melbourne's north, has programs for becoming carbon neutral, one of which is 'Zero Carbon Merri-bek', amongst other existing sustainable implementations and proposals. City of Melbourne. Over the past 10 years, various methods of improving public transport have been implemented, car free zones and entire streets have also been implemented. Sydney Sydney was ranked the most sustainable city in Australia by the 2018 Arcadis Sustainable Cities Index. While most cities in Australia ranked low in the green sustainability categories, a lot of them have made a remarkable shift to improve social sustainability by being more inclusive, supporting culture and general happiness among its people. City of Greater Taree, New South Wales The City of Greater Taree north of Sydney has developed a masterplan for Australia's first low-to-no carbon urban development. Austria Vienna is aiming for only 20% of trips to be made by automobile. Brazil Belo Horizonte, Brazil was created in 1897 and is the third-largest metropolis in Brazil, with 2.4 million inhabitants. The Strategic Plan for Belo Horizonte (2010–2030) is being prepared by external consultants based on similar cities' infrastructure, incorporating the role of local government, state government, city leaders and encouraging citizen participation. The need for environmentally sustainable development is led by the initiative of new government following planning processes from the state government. Overall, the development of the metropolis is dependent on the land regularization and infrastructure improvement that will better support the cultural technology and economic landscape. Despite being a developing or newly industrialized nation, it is home to two sustainable cities. The southern cities of Porto Alegre and Curitiba are often cited as examples of urban sustainability. Cameroon Bafut, is a town and traditional kingdom which is working towards becoming an eco-city by 2020, through the Bafut Council Eco-city Project. Canada Since 2016 the Green Score City Index has been studying the urban footprints of Canadian cities. It uses recognized governmental and institutional data to calculate the urban footprints of 50 cities. Vancouver had 2018's highest green score for large cities. Burlington had 2018's highest green score for medium cities. Victoria had 2018's highest green score for small cities. Most cities in Canada have sustainability action plans which are easily searched and downloaded from city websites. In 2010, Calgary ranked as the top eco-city in the planet for its, "excellent level of service on waste removal, sewage systems, and water drinkability and availability, coupled with relatively low air pollution." The survey was performed in conjunction with the reputable Mercer Quality of Living Survey. China The Chinese government has launched three sustainable city programs to promote pilot projects and foster innovation. Beginning in the early 2000s, China acknowledged the importance of sustainable development in addressing the challenges brought about by rapid urbanization and industrialization. As a result, hundreds of eco-city projects have been initiated throughout the country, making China home to the world's largest eco-city program. Tianjin: Sino-Singapore Tianjin Eco-city is a large and one of the first ecocity collaboration project created with the cooperation between China and Singapore, in November 2007, covering an area of 31.23 km². Locating at Binhai, Tianjin, it has been rated as the Eco-city with the most living experience in 2018. Dongtan Eco-city, Shanghai: The project, located in the east of Chongming Island developed by Arup and Parthers, was scheduled to accommodate 50,000 residents by 2010, but its developer has currently put construction on hold. An additional project was made in 2007 in this area: an Eco-Village based on the concept made by an Italian professor from the School of Architecture of Tianjin University. Huangbaiyu, Benxi, Liaoning is a small village of 42 homes that has come under great criticism: most of the homes are unoccupied by villagers. Nanjing: As of April 2008, an ecocity collaboration project is being proposed here. Rizhao, Shandong mandates solar water heaters for households, and has been designated the Environmental Model City by China's SEPA. Chengdu Tianfu District Great City is a planned city located just outside Chengdu that is planned to be sustainable and has the goal of being a self-sustaining city that discourages the use of cars. Dalian, Liaoning: The 100 MW Dalian Flow Battery Energy Storage Peak-shaving Power Station, with the largest power and capacity in the world so far, was connected to the grid in Dalian, China, on September 29, and it was put into operation in mid-October. Denmark Two comprehensive studies were carried out for the whole of Denmark in 2010 (The IDA Climate Plan 2050) and 2011 (The Danish Commission on Climate Change Policy). The studies analysed the benefits and obstacles of running Denmark on 100% renewable energy from the year 2050. There is also a larger, ambitious plan in action: the Copenhagen 2025 Climate Plan. On a more local level, the industrial park in Kalundborg is often cited as a model for industrial ecology. However, projects have been carried out in several Danish cities promoting 100% renewable energy. Examples include Aalborg, Ballerup and Frederikshavn. Aalborg University has launched a master education program on sustainable cities (Sustainable Cities @ Aalborg University Copenhagen). See also the Danish Wikipedia. Copenhagen: Cycling in Copenhagen: One of the most bicycle-friendly city's in the world where over 50% of the population get around on bikes. The city has infrastructure that caters to cycling with hundreds of kilometres of curb segregated bike lanes to separate cyclists and car traffic. A notable feature is The Cycle Super Highways which feature elevated bike lanes which ensure fast, unhindered travel between destinations. The city is aiming for just 25% of trips to be made by automobile. Ecuador Loja, Ecuador won three international prizes for the sustainability efforts begun by its mayor Dr. Jose Bolivar Castillo. Estonia Oxford Residences for four seasons in Estonia, winning a prize for Sustainable Company of the Year, is arguably one of the most advanced sustainable developments, not only trying to be carbon neutral, but already carbon negative. Finland The Finnish city of Turku has adopted a "Carbon Neutral Turku by 2040" strategy to achieve carbon neutrality via combining the goal with circular economy. VTT Technical Research Centre of Finland has formulated an EcoCity concept tailored to address the unique requirements of developing countries and emerging economies. Prominent reference examples include EcoCity Miaofeng in China, EcoNBC in Egypt, EcoGrad in St. Petersburg, Russia, UN Gigiri in Kenya, and MUF2013 in Tanzania. France In Paris, bike lanes are being doubled, while electric car incentives are being created. The French capital is banning the most polluting automobiles from key districts. Germany Freiburg im Breisgau often refers to itself as a green city. It is one of the few cities with a Green mayor and is known for its strong solar energy industry. Vauban, Freiburg is a sustainable model district. All houses are built to a low energy consumption standard and the whole district is designed to be car-free. Another green district in Freiburg is Rieselfeld, where houses generate more energy than they consume. There are several other green sustainable city projects such as Kronsberg in Hannover and current developments around Munich, Hamburg, and Frankfurt. Berlin: The Tiergarten (park) is a large park that takes up 520 acres and is an example of social sustainability where it is a green space but also used for transportation. The Tiergarten has inter paths where people can safely bike and walk without the disturbance of cars. Paths connect to notable areas within the city, such as government buildings, shopping areas and monuments. Berlin is mimicking London's "superhighways" for cyclists. Hong Kong The government portrays the proposed Hung Shui Kiu New Town as an eco-city. The same happened with the urban development plan on the site of the former Kai Tak Airport. Iran Isfahan dedicated smart city office began buildings architectures sustaintability programs in May 2022. Ireland South Dublin County Council announced plans in late 2007 to develop Clonburris, a new suburb of Dublin to include up to 15,000 new homes, to be designed to achieve the highest of international standards. The plans for Clonburris include countless green innovations such as high levels of energy efficiency, mandatory renewable energy for heating and electricity, the use of recycled and sustainable building materials, a district heating system for distributing heat, the provision of allotments for growing food, and even the banning of tumble driers, with natural drying areas being provided instead. In 2012 an energy plan was carried out by the Danish Aalborg University for the municipalities of Limerick and County Clare. The project was a short-term 2020 renewable energy strategy giving a 20% reduction in CO2 emissions, while ensuring that short-term actions are beneficial to the long-term goal of 100% renewable energy. India India is working on Gujarat International Finance Tec-City or GIFT which is an under-construction world-class city in the Indian state of Gujarat. It will come up on 500 acres (2.0 km2) land. It will also be first of its kind fully Sustainable City. Auroville was founded in 1968 with the intention of realizing human unity, and is now home to approximately 2,000 individuals from over 45 nations around the world. Its focus is its vibrant community culture and its expertise in renewable energy systems, habitat restoration, ecology skills, mindfulness practices, and holistic education. The new capital of Andhra Pradesh is also planned to be a sustainable city in the future. As a part of the UN Global Sustainable Development Goals (SDG) cities initiative, Noida in Uttar Pradesh was selected in 2018 to become one of 25 cities in the world to become models of SDGs by 2025. Indonesia The cities of Bandung, Cimahi, and Soreang in Indonesia become world leaders in zero waste cities program after significantly reducing the amount of waste and improving its management. Korea Songdo IBD is a planned city in Incheon which has incorporated a number of eco-friendly features. These include a central park irrigated with seawater, a subway line, bicycle lanes, rainwater catchment systems, and pneumatic waste collection system. 75% of the waste generated by the construction of the city will be recycled. Gwanggyo City Centre is another planned sustainable city. Malaysia As of 2014 a Low Carbon Cities programme is being piloted in Malaysia by KeTTHA, the Malaysian Ministry of Energy, Green Technology and Water, Malaysian Green Technology Corporation (GreenTech Malaysia) and the Carbon Trust. Malacca has a stated ambition to become a carbon-free city, taking steps towards creating a smart electricity grid. This is being done as part of an initiative to create a Green Special Economic Zone, where it is intended that as many as 20 research and development centers will be built focusing on renewable energy and clean technology, creating up to 300,000 new green jobs. The Federal Department of Town and Country Planning (FDTCP) in peninsular Malaysia is a focal point for the implementation of the Malaysian Urban Rural National Indicators Network for Sustainable Development (MURNInets), which includes 36 sets of compulsory indicators grouped under 21 themes under six dimensions. Most of the targets and standards for the selected indicators were adjusted according to hierarchy of local authorities. In MURNInets at least three main new features are introduced. These include the Happiness Index, an indicator under the quality of life theme to meet the current development trend that emphasizes on the well-being of the community. Another feature introduced is the customer or people satisfaction level towards local authorities' services. Through the introduction of these indicators the bottom-up approach in measuring sustainability is adopted. Morocco Planned for 2023, Zenata is the first African city to be awarded the Eco-City Label. It will include a total of 470 hectares of green spaces. It will also have water retention basins and promotes groundwater recharge and afforestation of the site. The naturally irrigated parks leading to the sea are designed as ecological corridors. New Zealand Waitakere City, a local body that formerly existed in West Auckland, was New Zealand's first eco-city, working from the Greenprint, a guiding document that the City Council developed in the early 1990s. Norway Oslo city was ranked first in the 2019 SDG Index and Dashboards Report for European Cities with a high score of 74.8. In order to achieve its ambitious targets for reducing carbon emissions in the European Green City index, Oslo plans to convert cities to biofuels and has considerably reduced traffic by 4–7% by introducing a congestion charge. Its aim is to cut-down emissions by 50 per cent since 1990 and it has taken a number of transportation, waste recycling, energy consumption and green space measures among others to meet its target. Philippines Clark Freeport Zone is a former United States Air Force base in the Philippines. It is located on the northwest side of Angeles City and on the west side of Mabalacat City in the province of Pampanga, about 40 miles (60 km) northwest of Metro Manila. A multi-billion project will convert the former Clark Air Force Base into a mix of industrial, commercial and institutional areas of green environment. The heart of the project is a 9,450-hectare metropolis dubbed as the "Clark Green City". Builders will use the green building system for environmentally-friendly structures. Its facilities will tap renewable energy such as solar and hydro power. Portugal The organization Living PlanIT is currently constructing a city from scratch near Porto, Portugal. Buildings will be electronically connected to vehicles giving the user a sense of personal eco-friendliness. Pakistan Islamabad The capital of Pakistan is full of green spaces and is an eco friendly city. Spain Bilbao: The city faced economic turmoil following the decline of the steel and port industries but through communication between stakeholders and authorities to create inner-city transformation, the local government benefited from the increase in land value in old port areas. The Strategic Plan for the Revitalisation of Metropolitan Bilbao was launched in 1992 and have flourished regenerating old steel and port industries. The conversion from depleted steel and port industries to one of Europe's most flourishing markets is a prime example of a sustainable project in action. Barcelona: The city is planning an urban redesign of civic super blocks, they plan to convert nine-block areas into unified mega block neighbourhoods. The aim is to decrease car-related traffic, noise and pollution by over 20% and to free up to 60% of road areas for reuse as citizen spaces. This is being done because they realized that people in Barcelona die prematurely due to poor air quality and everyday noise levels are deemed harmful. By converting roads to spaces for festivals, farmer markets, bikes, and walkability it promotes a healthier lifestyle and potentially a happier one. In 2020, the European Investment Bank approved a €95 million loan to assist Barcelona in the completion of approximately 40 projects, with an emphasis on climate change and social inequity. The city plans to redevelop streets to create more space for pedestrians and bicyclists, enhance building energy efficiency, and expand social, cultural, and recreational opportunities. Madrid: In 2018, Madrid banned all non-resident vehicles from its downtown areas. Saudi Arabia Saudi Arabia recently unveiled a proposed one of the most ambitious eco-city projects; Neom. Development is planned in the northwest region of the country along the Red Sea and would cover over 26,500 sq-km (10,230 sq-miles). Some of the most notable aspects of this development are The Line and Oxagon. The Line is advertised as a smart city that will stretch for 170 km with easily accessible amenities throughout. Oxagon is a planned floating city off the coast. If built, it will be the largest city. Sweden Norra Älvstranden (Swedish), in Gothenburg by the river Göta älv, is an example of a sustainable city in Sweden. It has low environmental impact, and contains passive houses, recycling system for waste, etc. Hammarby Sjöstad Västra Hamnen or Bo01, Malmö Stockholm Royal Seaport United Arab Emirates Masdar City, Abu Dhabi is a planned city that relies entirely on solar energy and other renewable energy sources, with a sustainable, zero-carbon, zero-waste ecology. Dubai The Sustainable City, Dubai United Kingdom London has committed to reaching net-zero carbon emissions by 2050. To do so, it aims to drastically reduce the proportion of trips made by cars and also ban all new petrol and diesel cars by 2035. Similarly, according to the UK Green Building Council, 40 per cent of UK's total carbon footprint comes from the built environment. Steel, which is used to make skyscrapers, is responsible for 7 per cent of the global emissions. Timber, especially CLT is a being considered as a great alternative to reduce construction-based emissions. The built environment is responsible for around 40% of the UK's total carbon footprint, according to the UK Green Building Council London Borough of Sutton is the first One Planet Region in the United Kingdom, with significant targets for reducing the ecological footprint of residents and creating the UK's greenest borough. Middlesbrough is another One Planet Region in the United Kingdom. Milton Keynes' original design concept aimed for a "forest city" and the foresters of the designers planted millions of trees from its own nursery in Newlands in the following years. Parks, lakes and green spaces cover about 25% of Milton Keynes; , there are 22 million trees and shrubs in public open spaces.

Physiology

Physiology (; ) is the scientific study of functions and mechanisms in a living system. As a subdiscipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out chemical and physical functions in a living system. According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology. Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells. Physiological state is the condition of normal function. In contrast, pathological state refers to abnormal conditions, including human diseases. The Nobel Prize in Physiology or Medicine is awarded by the Royal Swedish Academy of Sciences for exceptional scientific achievements in physiology related to the field of medicine. Foundations Because physiology focuses on the functions and mechanisms of living organisms at all levels, from the molecular and cellular level to the level of whole organisms and populations, its foundations span a range of key disciplines: Anatomy is the study of the structure and organization of living organisms, from the microscopic level of cells and tissues to the macroscopic level of organs and systems. Anatomical knowledge is important in physiology because the structure and function of an organism are often dictated by one another. Biochemistry is the study of the chemical processes and substances that occur within living organisms. Knowledge of biochemistry provides the foundation for understanding cellular and molecular processes that are essential to the functioning of organisms. Biophysics is the study of the physical properties of living organisms and their interactions with their environment. It helps to explain how organisms sense and respond to different stimuli, such as light, sound, and temperature, and how they maintain homeostasis, or a stable internal environment. Genetics is the study of heredity and the variation of traits within and between populations. It provides insights into the genetic basis of physiological processes and the ways in which genes interact with the environment to influence an organism's phenotype. Evolutionary biology is the study of the processes that have led to the diversity of life on Earth. It helps to explain the origin and adaptive significance of physiological processes and the ways in which organisms have evolved to cope with their environment. Subdisciplines There are many ways to categorize the subdisciplines of physiology: based on the taxa studied: human physiology, animal physiology, plant physiology, microbial physiology, viral physiology based on the level of organization: cell physiology, molecular physiology, systems physiology, organismal physiology, ecological physiology, integrative physiology based on the process that causes physiological variation: developmental physiology, environmental physiology, evolutionary physiology based on the ultimate goals of the research: applied physiology (e.g., medical physiology), non-applied (e.g., comparative physiology) Subdisciplines by level of organisation Cell physiology Although there are differences between animal, plant, and microbial cells, the basic physiological functions of cells can be divided into the processes of cell division, cell signaling, cell growth, and cell metabolism. Subdisciplines by taxa Plant physiology Plant physiology is a subdiscipline of botany concerned with the functioning of plants. Closely related fields include plant morphology, plant ecology, phytochemistry, cell biology, genetics, biophysics, and molecular biology. Fundamental processes of plant physiology include photosynthesis, respiration, plant nutrition, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, seed germination, dormancy, and stomata function and transpiration. Absorption of water by roots, production of food in the leaves, and growth of shoots towards light are examples of plant physiology. Animal physiology Human physiology Human physiology is the study of how the human body's systems and functions work together to maintain a stable internal environment. It includes the study of the nervous, endocrine, cardiovascular, respiratory, digestive, and urinary systems, as well as cellular and exercise physiology. Understanding human physiology is essential for diagnosing and treating health conditions and promoting overall wellbeing. It seeks to understand the mechanisms that work to keep the human body alive and functioning, through scientific enquiry into the nature of mechanical, physical, and biochemical functions of humans, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems within systems. The endocrine and nervous systems play major roles in the reception and transmission of signals that integrate function in animals. Homeostasis is a major aspect with regard to such interactions within plants as well as animals. The biological basis of the study of physiology, integration refers to the overlap of many functions of the systems of the human body, as well as its accompanied form. It is achieved through communication that occurs in a variety of ways, both electrical and chemical. Changes in physiology can impact the mental functions of individuals. Examples of this would be the effects of certain medications or toxic levels of substances. Change in behavior as a result of these substances is often used to assess the health of individuals. Much of the foundation of knowledge in human physiology was provided by animal experimentation. Due to the frequent connection between form and function, physiology and anatomy are intrinsically linked and are studied in tandem as part of a medical curriculum. Subdisciplines by research objective Comparative physiology Involving evolutionary physiology and environmental physiology, comparative physiology considers the diversity of functional characteristics across organisms. History The classical era The study of human physiology as a medical field originates in classical Greece, at the time of Hippocrates (late 5th century BC). Outside of Western tradition, early forms of physiology or anatomy can be reconstructed as having been present at around the same time in China, India and elsewhere. Hippocrates incorporated the theory of humorism, which consisted of four basic substances: earth, water, air and fire. Each substance is known for having a corresponding humor: black bile, phlegm, blood, and yellow bile, respectively. Hippocrates also noted some emotional connections to the four humors, on which Galen would later expand. The critical thinking of Aristotle and his emphasis on the relationship between structure and function marked the beginning of physiology in Ancient Greece. Like Hippocrates, Aristotle took to the humoral theory of disease, which also consisted of four primary qualities in life: hot, cold, wet and dry. Galen (–200 AD) was the first to use experiments to probe the functions of the body. Unlike Hippocrates, Galen argued that humoral imbalances can be located in specific organs, including the entire body. His modification of this theory better equipped doctors to make more precise diagnoses. Galen also played off of Hippocrates' idea that emotions were also tied to the humors, and added the notion of temperaments: sanguine corresponds with blood; phlegmatic is tied to phlegm; yellow bile is connected to choleric; and black bile corresponds with melancholy. Galen also saw the human body consisting of three connected systems: the brain and nerves, which are responsible for thoughts and sensations; the heart and arteries, which give life; and the liver and veins, which can be attributed to nutrition and growth. Galen was also the founder of experimental physiology. And for the next 1,400 years, Galenic physiology was a powerful and influential tool in medicine. Early modern period Jean Fernel (1497–1558), a French physician, introduced the term "physiology". Galen, Ibn al-Nafis, Michael Servetus, Realdo Colombo, Amato Lusitano and William Harvey, are credited as making important discoveries in the circulation of the blood. Santorio Santorio in 1610s was the first to use a device to measure the pulse rate (the pulsilogium), and a thermoscope to measure temperature. In 1791 Luigi Galvani described the role of electricity in the nerves of dissected frogs. In 1811, César Julien Jean Legallois studied respiration in animal dissection and lesions and found the center of respiration in the medulla oblongata. In the same year, Charles Bell finished work on what would later become known as the Bell–Magendie law, which compared functional differences between dorsal and ventral roots of the spinal cord. In 1824, François Magendie described the sensory roots and produced the first evidence of the cerebellum's role in equilibration to complete the Bell–Magendie law. In the 1820s, the French physiologist Henri Milne-Edwards introduced the notion of physiological division of labor, which allowed to "compare and study living things as if they were machines created by the industry of man." Inspired in the work of Adam Smith, Milne-Edwards wrote that the "body of all living beings, whether animal or plant, resembles a factory ... where the organs, comparable to workers, work incessantly to produce the phenomena that constitute the life of the individual." In more differentiated organisms, the functional labor could be apportioned between different instruments or systems (called by him as appareils). In 1858, Joseph Lister studied the cause of blood coagulation and inflammation that resulted after previous injuries and surgical wounds. He later discovered and implemented antiseptics in the operating room, and as a result, decreased the death rate from surgery by a substantial amount. The Physiological Society was founded in London in 1876 as a dining club. The American Physiological Society (APS) is a nonprofit organization that was founded in 1887. The Society is, "devoted to fostering education, scientific research, and dissemination of information in the physiological sciences." In 1891, Ivan Pavlov performed research on "conditional responses" that involved dogs' saliva production in response to a bell and visual stimuli. In the 19th century, physiological knowledge began to accumulate at a rapid rate, in particular with the 1838 appearance of the Cell theory of Matthias Schleiden and Theodor Schwann. It radically stated that organisms are made up of units called cells. Claude Bernard's (1813–1878) further discoveries ultimately led to his concept of milieu interieur (internal environment), which would later be taken up and championed as "homeostasis" by American physiologist Walter B. Cannon in 1929. By homeostasis, Cannon meant "the maintenance of steady states in the body and the physiological processes through which they are regulated." In other words, the body's ability to regulate its internal environment. William Beaumont was the first American to utilize the practical application of physiology. Nineteenth-century physiologists such as Michael Foster, Max Verworn, and Alfred Binet, based on Haeckel's ideas, elaborated what came to be called "general physiology", a unified science of life based on the cell actions, later renamed in the 20th century as cell biology. Late modern period In the 20th century, biologists became interested in how organisms other than human beings function, eventually spawning the fields of comparative physiology and ecophysiology. Major figures in these fields include Knut Schmidt-Nielsen and George Bartholomew. Most recently, evolutionary physiology has become a distinct subdiscipline. In 1920, August Krogh won the Nobel Prize for discovering how, in capillaries, blood flow is regulated. In 1954, Andrew Huxley and Hugh Huxley, alongside their research team, discovered the sliding filaments in skeletal muscle, known today as the sliding filament theory. Recently, there have been intense debates about the vitality of physiology as a discipline (Is it dead or alive?). If physiology is perhaps less visible nowadays than during the golden age of the 19th century, it is in large part because the field has given birth to some of the most active domains of today's biological sciences, such as neuroscience, endocrinology, and immunology. Furthermore, physiology is still often seen as an integrative discipline, which can put together into a coherent framework data coming from various different domains. Notable physiologists Women in physiology Initially, women were largely excluded from official involvement in any physiological society. The American Physiological Society, for example, was founded in 1887 and included only men in its ranks. In 1902, the American Physiological Society elected Ida Hyde as the first female member of the society. Hyde, a representative of the American Association of University Women and a global advocate for gender equality in education, attempted to promote gender equality in every aspect of science and medicine. Soon thereafter, in 1913, J.S. Haldane proposed that women be allowed to formally join The Physiological Society, which had been founded in 1876. On 3 July 1915, six women were officially admitted: Florence Buchanan, Winifred Cullis, Ruth Skelton, Sarah C. M. Sowton, Constance Leetham Terry, and Enid M. Tribe. The centenary of the election of women was celebrated in 2015 with the publication of the book "Women Physiologists: Centenary Celebrations And Beyond For The Physiological Society." Prominent women physiologists include: Bodil Schmidt-Nielsen, the first woman president of the American Physiological Society in 1975. Gerty Cori, along with her husband Carl Cori, received the Nobel Prize in Physiology or Medicine in 1947 for their discovery of the phosphate-containing form of glucose known as glycogen, as well as its function within eukaryotic metabolic mechanisms for energy production. Moreover, they discovered the Cori cycle, also known as the Lactic acid cycle, which describes how muscle tissue converts glycogen into lactic acid via lactic acid fermentation. Barbara McClintock was rewarded the 1983 Nobel Prize in Physiology or Medicine for the discovery of genetic transposition. McClintock is the only female recipient who has won an unshared Nobel Prize. Gertrude Elion, along with George Hitchings and Sir James Black, received the Nobel Prize for Physiology or Medicine in 1988 for their development of drugs employed in the treatment of several major diseases, such as leukemia, some autoimmune disorders, gout, malaria, and viral herpes. Linda B. Buck, along with Richard Axel, received the Nobel Prize in Physiology or Medicine in 2004 for their discovery of odorant receptors and the complex organization of the olfactory system. Françoise Barré-Sinoussi, along with Luc Montagnier, received the Nobel Prize in Physiology or Medicine in 2008 for their work on the identification of the Human Immunodeficiency Virus (HIV), the cause of Acquired Immunodeficiency Syndrome (AIDS). Elizabeth Blackburn, along with Carol W. Greider and Jack W. Szostak, was awarded the 2009 Nobel Prize for Physiology or Medicine for the discovery of the genetic composition and function of telomeres and the enzyme called telomerase.

Overconsumption (economics)

Overconsumption describes a situation where a consumer overuses their available goods and services to where they can't, or don't want to, replenish or reuse them. In microeconomics, this may be described as the point where the marginal cost of a consumer is greater than their marginal utility. The term overconsumption is quite controversial in use and does not necessarily have a single unifying definition. When used to refer to natural resources to the point where the environment is negatively affected, it is synonymous with the term overexploitation. However, when used in the broader economic sense, overconsumption can refer to all types of goods and services, including manmade ones, e.g. "the overconsumption of alcohol can lead to alcohol poisoning". Overconsumption is driven by several factors of the current global economy, including forces like consumerism, planned obsolescence, economic materialism, and other unsustainable business models and can be contrasted with sustainable consumption. Defining the amount of a natural resource required to be consumed for it to count as "overconsumption" is challenging because defining a sustainable capacity of the system requires accounting for many variables. The total capacity of a system occurs at both the regional and worldwide levels, which means that certain regions may have higher consumption levels of certain resources than others due to greater resources without overconsuming a resource. A long-term pattern of overconsumption in any given region or ecological system can cause a reduction in natural resources that often results in environmental degradation. However, this is only when applying the word to human impacts on the environment. When used in an economic sense, this point is defined as when the marginal cost of a consumer is equal to their marginal utility. Gossen's law of diminishing utility states that at this point, the consumer realizes the cost of consuming/purchasing another item/good is not worth the amount of utility (also known as happiness or satisfaction from the good) they'd receive, and therefore is not conducive to the consumer's wellbeing. When used in the environmental sense, the discussion of overconsumption often parallels that of population size and growth, and human development: more people demanding higher qualities of living, currently requires greater extraction of resources, which causes subsequent environmental degradation such as climate change and biodiversity loss. Currently, the inhabitants of high wealth, "developed" nations consume resources at a rate almost 32 times greater than those of the developing world, who make up the majority of the human population (7.9 billion people). However, the developing world is a growing consumer market. These nations are quickly gaining more purchasing power and it is expected that the Global South, which includes cities in Asia, America, and Africa, will account for 56% of consumption growth by 2030. This means that if current trends continue relative consumption rates will shift more into these developing countries, whereas developed countries would start to plateau. Sustainable Development Goal 12 "responsible consumption and production" is the main international policy tool with goals to abate the impact of overconsumption. Causes Economic growth Economic growth is sometimes seen as a driver for overconsumption. Economic growth can be seen as a catalyst of overconsumption due to it requiring greater resource input to sustain the growth. China is an example where this phenomenon has been observed readily. China’s GDP increased massively from 1978, and energy consumption has increased by 6-fold. By 1983, China’s consumption surpassed the biocapacity of their natural resources, leading to overconsumption. In the last 30–40 years, China has seen significant increases in its pollution, land degradation, and non-renewable resource depletion, which aligns with its considerable economic growth. It is unknown if other rapidly developing nations will see similar trends in resource overconsumption. The Worldwatch Institute said China and India, with their booming economies, along with the United States, are the three planetary forces that are shaping the global biosphere. The State of the World 2005 report said the two countries' high economic growth exposed the reality of severe pollution. The report states that The world's ecological capacity is simply insufficient to satisfy the ambitions of China, India, Japan, Europe, and the United States as well as the aspirations of the rest of the world in a sustainable way. In 2019, a warning on the climate crisis signed by 11,000 scientists from over 150 nations said economic growth is the driving force behind the "excessive extraction of materials and overexploitation of ecosystems" and that this "must be quickly curtailed to maintain long-term sustainability of the biosphere." Also in 2019, the Global Assessment Report on Biodiversity and Ecosystem Services published by the United Nations' Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, which found that up to one million species of plants and animals are at risk of extinction from human activity, asserted that A key element of more sustainable future policies is the evolution of global financial and economic systems to build a global sustainable economy, steering away from the current limited paradigm of economic growth. Consumerism Consumerism is a social and economic order that encourages the acquisition of goods and services in ever-increasing amounts. There is a spectrum of goods and services that the world population constantly consumes. These range from food and beverage, clothing and footwear, housing, energy, technology, transportation, education, health and personal care, financial services, and other utilities. When the resources required to produce these goods and services are depleted beyond a reasonable level, it can be considered to be overconsumption. Because developing nations are rising quickly into the consumer class, the trends happening in these nations are of special interest. According to the World Bank, the highest shares of consumption, regardless of income lie in food, beverage, clothing, and footwear. As of 2015, the top five consumer markets in the world were the United States, Japan, Germany, China, and France. Planned and perceived obsolescence is an important factor that explains why some overconsumption of consumer products exists. This factor of the production revolves around designing products with the intent to be discarded after a short period of time. Perceived obsolescence is prevalent within the fashion and technology industries. Through this technique, products are made obsolete and replaced on a semi-regular basis. Frequent new launches of technology or fashion lines can be seen as a form of marketing-induced perceived obsolescence. Products designed to break after a certain period of time or use would be considered to be planned obsolescence. Affluence According to a 2020 paper written by a team of scientists titled "Scientists' warning on affluence", the entrenchment of "capitalist, growth-driven economic systems" since World War II gave rise to increasing affluence along with "enormous increases in inequality, financial instability, resource consumption and environmental pressures on vital earth support systems." And the world's wealthiest citizens, referred to as "super-affluent consumers . . . which overlap with powerful fractions of the capitalist class," are the most responsible for environmental impacts through their consumption patterns worldwide. Any sustainable social and environmental pathways must include transcending paradigms fixated on economic growth and also reducing, not simply "greening", the overconsumption of the super-affluent, the authors contend, and propose adopting either reformist policies which can be implemented within a capitalist framework such as wealth redistribution through taxation (in particular eco-taxes), green investments, basic income guarantees and reduced work hours to accomplish this, or looking to more radical approaches associated with degrowth, eco-socialism and eco-anarchism, which would "entail a shift beyond capitalism and/or current centralised states." Effects A fundamental effect of overconsumption is a reduction in the planet's carrying capacity. Excessive unsustainable consumption will exceed the long-term carrying capacity of its environment (ecological overshoot) and subsequent resource depletion, environmental degradation and reduced ecosystem health. In 2020 multinational team of scientists published a study, saying that overconsumption is the biggest threat to sustainability. According to the study, a drastic lifestyle change is necessary for solving the ecological crisis. According to one of the authors Julia Steinberger: “To protect ourselves from the worsening climate crisis, we must reduce inequality and challenge the notion that riches, and those who possess them, are inherently good.” The research was published on the site of the World Economic Forum. The leader of the forum professor Klaus Schwab, calls to a "great reset of capitalism". A 2020 study published in Scientific Reports, in which both population growth and deforestation were used as proxies for total resource consumption, warns that if consumption continues at the current rate for the next several decades, it can trigger a full or almost full extinction of humanity. The study says that "while violent events, such as global war or natural catastrophic events, are of immediate concern to everyone, a relatively slow consumption of the planetary resources may be not perceived as strongly as a mortal danger for the human civilization." To avoid it humanity should pass from a civilization dominated by the economy to a "cultural society" that "privileges the interest of the ecosystem above the individual interest of its components, but eventually in accordance with the overall communal interest." The scale of modern life's overconsumption can lead to a decline in economy and an increase in financial instability. Some argue that overconsumption enables the existence of an "overclass", while others disagree with the role of overconsumption in class inequality. Population, Development, and Poverty all coincide with overconsumption; how they interplay with each other is complex. Because of this complexity it is difficult to determine the role of consumption in terms of economic inequality. In the long term, these effects can lead to increased conflict over dwindling resources and in the worst case a Malthusian catastrophe. Lester Brown of the Earth Policy Institute, has said: "It would take 1.5 Earths to sustain our present level of consumption. Environmentally, the world is in an overshoot mode." As of 2012, the United States alone was using 30% of the world's resources and if everyone were to consume at that rate, we would need 3-5 planets to sustain this type of living. Resources are quickly becoming depleted, with about ⅓ already gone. With new consumer markets rising in the developing countries which account for a much higher percentage of the world's population, this number can only rise. According to Sierra Club’s Dave Tilford, "With less than 5 percent of world population, the U.S. uses one-third of the world’s paper, a quarter of the world’s oil, 23 percent of the coal, 27 percent of the aluminum, and 19 percent of the copper." According to BBC, a World Bank study has found that "Americans produce 16.5 tonnes of carbon dioxide per capita every year. By comparison, only 0.1 tonnes of the greenhouse gas is generated in Ethiopia per inhabitant." A 2021 study published in Frontiers in Conservation Science posits that aggregate consumption growth will continue into the near future and perhaps beyond, largely due to increasing affluence and population growth. The authors argue that "there is no way—ethically or otherwise (barring extreme and unprecedented increases in human mortality)—to avoid rising human numbers and the accompanying overconsumption", although they do say that the negative impacts of overconsumption can perhaps be diminished by implementing human rights policies to lower fertility rates and decelerate current consumption patterns. Effects on health A report from the Lancet Commission says the same. The experts write: "Until now, undernutrition and obesity have been seen as polar opposites of either too few or too many calories," "In reality, they are both driven by the same unhealthy, inequitable food systems, underpinned by the same political economy that is single-focused on economic growth, and ignores the negative health and equity outcomes. Climate change has the same story of profits and power,". Obesity was a medical problem for people who overconsumed food and worked too little already in ancient Rome, and its impact slowly grew through history. As to 2012, mortality from obesity was 3 times larger than from hunger, reaching 2.8 million people per year by 2017 Overuse of artificial energy, for example, in cars, hurts health and the planet. Promoting active living and reducing sedentary lifestyle, for example, by cycling, reduces greenhouse gas emissions and improve health Global estimates In 2010, the International Resource Panel published the first global scientific assessment on the impacts of consumption and production. The study found that the most critical impacts are related to ecosystem health, human health and resource depletion. From a production perspective, it found that fossil-fuel combustion processes, agriculture and fisheries have the most important impacts. Meanwhile, from a final consumption perspective, it found that household consumption related to mobility, shelter, food, and energy-using products causes the majority of life-cycle impacts of consumption. According to the IPCC Fifth Assessment Report, human consumption, with current policy, by the year 2100 will be seven times bigger than in the year 2010. Footprint The idea of overconsumption is also strongly tied to the idea of an ecological footprint. The term "ecological footprint" refers to the "resource accounting framework for measuring human demand on the biosphere." Currently, China, for instance, has a per person ecological footprint roughly half the size of the US, yet has a population that is more than four times the size of the US. It is estimated that if China developed to the level of the United States that world consumption rates would roughly double. Humans, their prevailing growth of demands for livestock and other domestic animals, has added overshoot through domestic animal breeding, keeping, and consumption, especially with the environmentally destructive industrial livestock production. Globalization and modernization have brought Western consumer cultures to countries like China and India, including meat-intensive diets which are supplanting traditional plant-based diets. Between 166 to more than 200 billion land and aquatic animals are consumed by a global population of over 7 billion annually. A 2018 study published in Science postulates that meat consumption is set to increase as the result of human population growth and rising affluence, which will increase greenhouse gas emissions and further reduce biodiversity. Meat consumption needs to be reduced in order to make agriculture sustainable by up to 90% according to a 2018 study published in Nature. 56% of respondents to a 2022 climate survey support a carbon budget system to limit the most climate-damaging consumption (62% of those under 30). Counteractions The most obvious solution to the issue of overconsumption is to simply slow the rate at which materials are becoming depleted. From a capitalistic point of view, less consumption has negative effects on economies and so instead, countries must look to curb consumption rates but also allow for new industries, such as renewable energy and recycling technologies, to flourish and deflect some of the economic burdens. Some movements think that a reduction in consumption in some cases can benefit the economy and society. They think that a fundamental shift in the global economy may be necessary to account for the current change that is taking place or that will need to take place. Movements and lifestyle choices related to stopping overconsumption include: anti-consumerism, freeganism, green economics, ecological economics, degrowth, frugality, downshifting, simple living, minimalism, the slow movement, and thrifting. Many consider the final target of the movements as arriving to a steady-state economy in which the rate of consumption is optimal for health and environment. Recent grassroots movements have been coming up with creative ways to decrease the number of goods we consume. The Freecycle Network is a network of people in one's community that are willing to trade goods for other goods or services. It is a new take on thrifting while still being beneficial to both parties. Other researchers and movements such as the Zeitgeist Movement suggest a new socioeconomic model which, through a structural increase of efficiency, collaboration and locality in production as well as effective sharing, increased modularity, sustainability and optimal design of products, are expected to reduce resource-consumption. Solutions offered include consumers using market forces to influence businesses towards more sustainable manufacturing and products. Another way to reduce consumption is to slow population growth by improving family planning services worldwide. In developing countries, more than 200 million women do not have adequate access. Women's empowerment in these countries will also result in smaller families.

Environmental protection

Environmental protection is the practice of protecting the natural environment by individuals, groups and governments. Its objectives are to conserve natural resources and the existing natural environment and, where it is possible, to repair damage and reverse trends. Due to the pressures of overconsumption, population growth and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that cause environmental degradation. Since the 1960s, environmental movements have created more awareness of the multiple environmental problems. There is disagreement on the extent of the environmental impact of human activity, so protection measures are occasionally debated. Approaches to environmental protection Voluntary environmental agreements In industrial countries, voluntary environmental agreements often provide a platform for companies to be recognized for moving beyond the minimum regulatory standards and thus support the development of the best environmental practice. For instance, in India, Environment Improvement Trust (EIT) has been working for environmental and forest protection since 1998. In developing countries, such as Latin America, these agreements are more commonly used to remedy significant levels of non-compliance with mandatory regulation. Ecosystems approach An ecosystems approach to resource management and environmental protection aims to consider the complex interrelationships of an entire ecosystem in decision-making rather than simply responding to specific issues and challenges. Ideally, the decision-making processes under such an approach would be a collaborative approach to planning and decision-making that involves a broad range of stakeholders across all relevant governmental departments, as well as industry representatives, environmental groups, and community. This approach ideally supports a better exchange of information, development of conflict-resolution strategies and improved regional conservation. Religions also play an important role in the conservation of the environment: for example, the Catholic Church's Compendium on its social teaching states that "environmental protection cannot be assured solely on the basis of financial calculations of costs and benefits. The environment is one of those goods that cannot be adequately safeguarded or promoted by market forces." International environmental agreements Many of the earth's resources are especially vulnerable because they are influenced by human impacts across different countries. As a result of this, many attempts are made by countries to develop agreements that are signed by multiple governments to prevent damage or manage the impacts of human activity on natural resources. This can include agreements that impact factors such as climate, oceans, rivers and air pollution. These international environmental agreements are sometimes legally binding documents that have legal implications when they are not followed and, at other times, are more agreements in principle or are for use as codes of conduct. These agreements have a long history with some multinational agreements being in place from as early as 1910 in Europe, America and Africa. Many of the international technical agencies formed after 1945 addressed environmental themes. By the late 1960s, a growing environmental movement called for coordinated and institutionalized international cooperation. The landmark United Nations Conference on the Human Environment was held in Stockholm in 1972, establishing the concept of a right to a healthy environment. It was followed by the creation of the United Nations Environment Programme later that year. Some of the most well-known international agreements include the Kyoto Protocol of 1997 and the Paris Agreement of 2015. On 8 October 2021, the UN Human Rights Council passed a resolution recognizing access to a healthy and sustainable environment as a universal right. In the resolution 48/13, the Council called on States around the world to work together, and with other partners, to implement the newly recognized right. On 28 July 2022, the United Nations General Assembly voted to declare the ability to live in "a clean, healthy and sustainable environment" a universal human right. Government Discussion concerning environmental protection often focuses on the role of government, legislation, and law enforcement. However, in its broadest sense, environmental protection may be seen to be the responsibility of all the people and not simply that of government. Decisions that impact the environment will ideally involve a broad range of stakeholders including industry, indigenous groups, environmental group and community representatives. Gradually, environmental decision-making processes are evolving to reflect this broad base of stakeholders and are becoming more collaborative in many countries. Africa Tanzania Many constitutions acknowledge Tanzania as having some of the greatest biodiversity of any African country. Almost 40% of the land has been established into a network of protected areas, including several national parks. The concerns for the natural environment include damage to ecosystems and loss of habitat resulting from population growth, expansion of subsistence agriculture, pollution, timber extraction and significant use of timber as fuel. Environmental protection in Tanzania began during the German occupation of East Africa (1884–1919)—colonial conservation laws for the protection of game and forests were enacted, whereby restrictions were placed upon traditional indigenous activities such as hunting, firewood collecting, and cattle grazing. In 1948, Serengeti has officially established the first national park for wild cats in East Africa. Since 1983, there has been a more broad-reaching effort to manage environmental issues at a national level, through the establishment of the National Environment Management Council (NEMC) and the development of an environmental act. Division of the biosphere is the main government body that oversees protection. It does this through the formulation of policy, coordinating and monitoring environmental issues, environmental planning and policy-oriented environmental research. The National Environment Management Council (NEMC) is an institution that was initiated when the National Environment Management Act was first introduced in year 1983. This council has the role to advise governments and the international community on a range of environmental issues. The NEMC the following purposes: provide technical advice; coordinate technical activities; develop enforcement guidelines and procedures; assess, monitor and evaluate activities that impact the environment; promote and assist environmental information and communication; and seek advancement of scientific knowledge. The National Environment Policy of 1997 acts as a framework for environmental decision making in Tanzania. The policy objectives are to achieve the following: Ensure sustainable and equitable use of resources without degrading the environment or risking health or safety. Prevent and control degradation of land, water, vegetation and air. Conserve and enhance natural and man-made heritage, including biological diversity of unique ecosystems. Improve condition and productivity of degraded areas. Raise awareness and understanding of the link between environment and development. Promote individual and community participation. Promote international cooperation. Use ecofriendly resources. Tanzania is a signatory to a significant number of international conventions including the Rio Declaration on Development and Environment 1992 and the Convention on Biological Diversity 1996. The Environmental Management Act, 2004, is the first comprehensive legal and institutional framework to guide environmental-management decisions. The policy tools that are parts of the act include the use of environmental-impact assessments, strategics environmental assessments, and taxation on pollution for specific industries and products. The effectiveness of shifting of this act will only become clear over time as concerns regarding its implementation become apparent based on the fact that, historically, there has been a lack of capacity to enforce environmental laws and a lack of working tools to bring environmental-protection objectives into practice. Asia China Formal environmental protection in China House was first stimulated by the 1972 United Nations Conference on the Human Environment held in Stockholm, Sweden. Following this, they began establishing environmental protection agencies and putting controls on some of its industrial waste. China was one of the first developing countries to implement a sustainable development strategy. In 1983 the State Council announced that environmental protection would be one of China's basic national policies and in 1984 the National Environmental Protection Agency (NEPA) was established. Following severe flooding of the Yangtze River basin in 1998, NEPA was upgraded to the State Environmental Protection Agency (SEPA) meaning that environmental protection was now being implemented at a ministerial level. In 2008, SEPA became known by its current name of Ministry of Environmental Protection of the People's Republic of China (MEP). Environmental pollution and ecological degradation has resulted in economic losses for China. In 2005, economic losses (mainly from air pollution) were calculated at 7.7% of China's GDP. This grew to 10.3% by 2002 and the economic loss from water pollution (6.1%) began to exceed that caused by air pollution. China has been one of the top performing countries in terms of GDP growth (9.64% in the past ten years). However, the high economic growth has put immense pressure on its environment and the environmental challenges that China faces are greater than most countries. In 2021 it was noted that China was the world's largest greenhouse gas emitter, while also facing additional environmental challenges which included illegal logging, wildlife trafficking, plastic waste, ocean pollution, environmental-related mismanagement, unregulated fishing, and the consequences associated with being the world's largest mercury polluter. All these factors contribute to climate change and habitat loss. In 2022 China was ranked 160th out of 180 countries on the Environmental Performance Index due to poor air quality and high GHG emissions. Ecological and environmental degradation in China have health related impacts; for example, if current pollution levels continue, Chinese citizens will lose 3.6 billion total life years. Another issue is that non-transmittable diseases among Chinese, which cause at least 80% of 10.3 million annual deaths, are worsened by air pollution. China has taken initiatives to increase its protection of the environment and combat environmental degradation: China's investment in renewable energy grew 18% in 2007 to $15.6 billion, accounting for ~10% of the global investment in this area; In 2008, spending on the environment was 1.49% of GDP, up 3.4 times from 2000; The discharge of CO (carbon monoxide) and SO2 (sulfur dioxide) decreased by 6.61% and 8.95% in 2008 compared with that in 2005; China's protected nature reserves have increased substantially. In 1978 there were only 34 compared with 2,538 in 2010. The protected nature reserve system now occupies 15.5% of the country; this is higher than the world average. Rapid growth in GDP has been China's main goal during the past three decades with a dominant development model of inefficient resource use and high pollution to achieve high GDP. For China to develop sustainably, environmental protection should be treated as an integral part of its economic policies. Quote from Shengxian Zhou, head of MEP (2009): "Good economic policy is good environmental policy and the nature of environmental problem is the economic structure, production form and develop model." Since around 2010 China appears to be placing a greater emphasis on environmental and ecological protection. For example, former General Secretary Hu Jintao's report at the 2012 Party Congress added a section focusing on party policy on ecological issues. Xi Jinping's report at the 19th CPC National Congress in 2017 noted recent progress in ecological and environmental conservation and restoration, the importance of ecologically sustainable development and global ecological security, and the need to provide ecological goods to meet people's growing demands. Most importantly, Xi Jinping has suggested clearly identifiable methods to meet the ecological demands of the country. Some of the solutions he notes are the need for the development and facilitation of: ecological corridors, biodiversity protection networks, redlines for protecting ecosystems, market-based mechanisms for ecological compensation in addition to afforestation, greater crop rotation, recycling, waste reduction, stricter pollution standards, and greener production and technology. The report at the 19th CPC National Congress isn't simply the personal thoughts from Xi Jinping, it's a product of a long process of compromise and negotiation among competing party officials and leaders. Additionally, the Third Plenum of the CCP in 2013 included a manifesto that placed extreme emphasis on reforming management of the environment, promising to create greater transparency of those polluting, and placing environmental criteria above GDP growth for local official evaluations. Reform has not come cheap for China. In 2016, it was noted that in response to pollution and oversupply, China laid off around six million workers in state-owned enterprises and spent $23 billion to cover layoffs specifically for coal and steel companies between 2016 and 2019. While expensive, other benefits of environmental protection have been noticed beyond impacting citizens' health. For example, in the long run, environmental protection has been found to generally improve job quality of migrant workers by reducing their work intensity, while increasing social security and job quality. Different local governments in China implement different approaches to solving the issue of ecological protection, sometimes with negative consequences for the citizens. For example, a prefecture in the Shanxi province imposed bans, and potential legal detentions or steep fines for violations, on coal-burning by villagers. Although the government provided free gas-heaters often the villagers were unable to afford to run them. In Wuhan, automated surveillance technology and video is used to catch illegal fishing, and in some cities not recycling results in negative social credit points. It is unclear in some of these instances if citizens have any potential routes for recourse. News in 2023 has found that the Chinese Communist Party's recent war on pollution has already brought substantial and measurable impacts, including China's particulate pollution levels dropping 42% from 2013 levels and increasing the average lifespan expectancy of citizens by an estimated 2.2 years. India The Constitution of India has a number of provisions demarcating the responsibility of the Central and State governments towards Environmental Protection. The state's responsibility with regard to environmental protection has been laid down under article 48-A of the constitution which stated that "The states shall endeavor to protect and improve the environment and to safeguard the forest and wildlife of the country". Environmental protection has been made a fundamental duty of every citizen of India under Article 51-A (g) of the constitution which says "It shall be the duty of every citizen of India to protect and improve the natural environment including forests, lakes, rivers, and wildlife and to have compassion for living creatures". Article 21 of the constitution is a fundamental right, which states that "No person shall be deprived of his life or personal liberty except according to the procedure established by law". Middle East The Middle Eastern countries become part of the joint Islamic environmental action, which was initiated in 2002 in Jeddah. Under the Islamic Educational, Scientific and Cultural Organization, the member states join the Islamic Environment Ministers Conference in every two years, focusing on the importance of environment protection and sustainable development. The Arab countries are also awarded the title of best environment management in the Islamic world. In August 2019, the Sultanate of Oman won the award for 2018–19 in Saudi Arabia, citing its project "Verifying the Age and Growth of Spotted Small Spots in the Northwest Coast of the Sea of Oman". Russia In Russia, environmental protection is considered an integral part of national safety. The Federal Ministry of Natural Resources and Ecology is the authorized state body tasked with managing environmental protection. However, there are a lot of environmental issues in Russia. Europe European Union Environmental protection has become an important task for the institutions of the European Community after the Maastricht Treaty for the European Union ratification by all of its member states. The EU is active in the field of environmental policy, issuing directives such as those on environmental impact assessment and on access to environmental information for citizens in the member states. Ireland The Environmental Protection Agency, Ireland (EPA) has a wide range of functions to protect the environment, with its primary responsibilities including: Environmental licensing Enforcement of environmental law Environmental planning, education, and guidance Monitoring, analyzing and reporting on the environment Regulating Ireland's greenhouse gas emissions Environmental research development Strategic environmental assessment Waste management Radiological protection Switzerland The environmental protection in Switzerland is mainly based on the measures to be taken against global warming. The pollution in Switzerland is mainly the pollution caused by vehicles and the litteration by tourists. Latin America The United Nations Environment Programme (UNEP) has identified 17 megadiverse countries. The list includes six Latin American countries: Brazil, Colombia, Ecuador, Mexico, Peru and Venezuela. Mexico and Brazil stand out among the rest because they have the largest area, population and number of species. These countries represent a major concern for environmental protection because they have high rates of deforestation, ecosystems loss, pollution, and population growth. Brazil Brazil has the largest amount of the world's tropical forests, 4,105,401 km2 (48.1% of Brazil), concentrated in the Amazon region. Brazil is home to vast biological diversity, first among the megadiverse countries of the world, having between 15%-20% of the 1.5 million globally described species. The organization in charge of environment protection is the Brazilian Ministry of the Environment (in Portuguese: Ministério do Meio Ambiente, MMA). It was first created in the year 1973 with the name Special Secretariat for the Environment (Secretaria Especial de Meio Ambiente), changing names several times, and adopting the final name in the year 1999. The Ministry is responsible for addressing the following issues: A national policy for the environment and for water resources; A policy for the preservation, conservation and sustainable use of ecosystems, biodiversity, and forests; Proposing strategies, mechanisms, economic and social instruments for improving environmental quality, and sustainable use of natural resources; Policies for integrating production and the environment; Environmental policies and programs for the Legal Amazon; Ecological and economic territorial zoning. In 2011, protected areas of the Amazon covered 2,197,485 km2 (an area larger than Greenland), with conservation units, like national parks, accounting for just over half (50.6%) and indigenous territories representing the remaining 49.4%. Mexico With over 200,000 different species, Mexico is home to 10–12% of the world's biodiversity, ranking first in reptile biodiversity and second in mammals—one estimate indicates that over 50% of all animal and plant species live in Mexico. The history of environmental policy in Mexico started in the 1940s with the enactment of the Law of Conservation of Soil and Water (in Spanish: Ley de Conservación de Suelo y Agua). Three decades later, at the beginning of the 1970s, the Law to Prevent and Control Environmental Pollution was created (Ley para Prevenir y Controlar la Contaminación Ambiental). In the year 1972 was the first direct response from the federal government to address eminent health effects from environmental issues. It established the administrative organization of the Secretariat for the Improvement of the Environment (Subsecretaría para el Mejoramiento del Ambiente) in the Department of Health and Welfare. The Secretariat of Environment and Natural Resources (Secretaría del Medio Ambiente y Recursos Naturales, SEMARNAT) is Mexico's environment ministry. The Ministry is responsible for addressing the following issues: Promote the protection, restoration, and conservation of ecosystems, natural resources, goods, and environmental services and facilitate their use and sustainable development. Develop and implement a national policy on natural resources Promote environmental management within the national territory, in coordination with all levels of government and the private sector. Evaluate and provide determination to the environmental impact statements for development projects and prevention of ecological damage Implement national policies on climate change and protection of the ozone layer. Direct work and studies on national meteorological, climatological, hydrological, and geohydrological systems, and participate in international conventions on these subjects. Regulate and monitor the conservation of waterways In November 2000 there were 127 protected areas; currently there are 174, covering an area of 25,384,818 hectares, increasing federally protected areas from 8.6% to 12.85% of its land area. Oceania Australia In 2008, there was 98,487,116 ha of terrestrial protected area, covering 12.8% of the land area of Australia. The 2002 figures of 10.1% of terrestrial area and 64,615,554 ha of protected marine area were found to poorly represent about half of Australia's 85 bioregions. Environmental protection in Australia could be seen as starting with the formation of the first national park, Royal National Park, in 1879. More progressive environmental protection had it start in the 1960s and 1970s with major international programs such as the United Nations Conference on the Human Environment in 1972, the Environment Committee of the OECD in 1970, and the United Nations Environment Programme of 1972. These events laid the foundations by increasing public awareness and support for regulation. State environmental legislation was irregular and deficient until the Australian Environment Council (AEC) and Council of Nature Conservation Ministers (CONCOM) were established in 1972 and 1974, creating a forum to assist in coordinating environmental and conservation policies between states and neighbouring countries. These councils have since been replaced by the Australian and New Zealand Environment and Conservation Council (ANZECC) in 1991 and finally the Environment Protection and Heritage Council (EPHC) in 2001. At a national level, the Environment Protection and Biodiversity Conservation Act 1999 is the primary environmental protection legislation for the Commonwealth of Australia. It concerns matters of national and international environmental significance regarding flora, fauna, ecological communities and cultural heritage. It also has jurisdiction over any activity conducted by the Commonwealth, or affecting it, that has significant environmental impact. The act covers eight main areas: National Heritage Sites World Heritage Sites Ramsar wetlands Nationally endangered or threatened species and ecological communities Nuclear activities and actions Great Barrier Reef Marine Park Migratory species Commonwealth marine areas There are several Commonwealth protected lands due to partnerships with traditional native owners, such as Kakadu National Park, extraordinary biodiversity such as Christmas Island National Park, or managed cooperatively due to cross-state location, such as the Australian Alps National Parks and Reserves. At a state level, the bulk of environmental protection issues are left to the responsibility of the state or territory. Each state in Australia has its own environmental protection legislation and corresponding agencies. Their jurisdiction is similar and covers point source pollution, such as from industry or commercial activities, land/water use, and waste management. Most protected lands are managed by states and territories with state legislative acts creating different degrees and definitions of protected areas such as wilderness, national land and marine parks, state forests, and conservation areas. States also create regulation to limit and provide general protection from air, water, and sound pollution. At a local level, each city or regional council has responsibility over issues not covered by state or national legislation. This includes non-point source, or diffuse pollution, such as sediment pollution from construction sites. Australia ranks second place on the UN 2010 Human Development Index and one of the lowest debt to GDP ratios of the developed economies. This could be seen as coming at the cost of the environment, with Australia being the world leader in coal exportation and species extinctions. Some have been motivated to proclaim it is Australia's responsibility to set the example of environmental reform for the rest of the world to follow. New Zealand At a national level, the Ministry for the Environment is responsible for environmental policy and the Department of Conservation addresses conservation issues. At a regional level the regional councils administer the legislation and address regional environmental issues. United States Since 1970, the United States Environmental Protection Agency (EPA) has been working to protect the environment and human health. The Environmental Protection Agency (EPA) is an independent executive agency of the United States federal government tasked with environmental protection matters. All US states have their own state-level departments of environmental protection, which may issue regulations more stringent than the federal ones. In January 2010, EPA Administrator Lisa P. Jackson published via the official EPA blog her "Seven Priorities for EPA's Future", which were (in the order originally listed): Taking action on climate change Improving air quality Assuring the safety of chemicals Cleaning up [US] communities Protecting America's waters Expanding the conversation on environmentalism and working for environmental justice Building strong state and tribal partnerships it is unclear whether these still represent the agency's active priorities, as Jackson departed in February 2013, and the page has not been updated in the interim. In literature There are numerous works of literature that contain the themes of environmental protection but some have been fundamental to its evolution. Several pieces such as A Sand County Almanac by Aldo Leopold, "Tragedy of the commons" by Garrett Hardin, and Silent Spring by Rachel Carson have become classics due to their far reaching influences. The conservationist and Nobel laureate Wangari Muta Maathai devoted her 2010 book Replenishing the Earth to the Green Belt Movement and the vital importance of trees in protecting the environment. The subject of environmental protection is present in fiction as well as non-fictional literature. Books such as Antarctica and Blockade have environmental protection as subjects whereas The Lorax has become a popular metaphor for environmental protection. "The Limits of Trooghaft" by Desmond Stewart is a short story that provides insight into human attitudes towards animals. Another book called The Martian Chronicles by Ray Bradbury investigates issues such as bombs, wars, government control, and what effects these can have on the environment.

Situation, task, action, result

The situation, task, action, result (STAR) format is a technique used by interviewers to gather all the relevant information about a specific capability that the job requires. Situation: The interviewer wants you to present a recent challenging situation in which you found yourself. Task: What were you required to achieve? The interviewer will be looking to see what you were trying to achieve from the situation. Some performance development methods use “Target” rather than “Task”. Job interview candidates who describe a “Target” they set themselves instead of an externally imposed “Task” emphasize their own intrinsic motivation to perform and to develop their performance. Action: What did you do? The interviewer will be looking for information on what you did, why you did it and what the alternatives were. Results: What was the outcome of your actions? What did you achieve through your actions? Did you meet your objectives? What did you learn from this experience? Have you used this learning since? The STAR technique is similar to the SOARA technique (Situation, Objective, Action, Result, Aftermath). The STAR technique is also often complemented with an additional R on the end STARR or STAR(R) with the last R resembling reflection. This R aims to gather insight and interviewee's ability to learn and iterate. Whereas the STAR reveals how and what kind of result on an objective was achieved, the STARR with the additional R helps the interviewer to understand what the interviewee learned from the experience and how they would assimilate experiences. The interviewee can define what they would do (differently, the same, or better) next time being posed with a situation. Common questions that the STAR technique can be applied to include conflict management, time management, problem solving and interpersonal skills.

Sustainable management

Sustainable management takes the concepts from sustainability and synthesizes them with the concepts of management. Sustainability has three branches: the environment, the needs of present and future generations, and the economy. Using these branches, it creates the ability of a system to thrive by maintaining economic viability and also nourishing the needs of the present and future generations by limiting resource depletion. Sustainable management is needed because it is an important part of the ability to successfully maintain the quality of life on our planet. Sustainable management can be applied to all aspects of our lives. For example, the practices of a business should be sustainable if they wish to stay in businesses, because if the business is unsustainable, then by the definition of sustainability they will cease to be able to be in competition. Communities are in a need of sustainable management, because if the community is to prosper, then the management must be sustainable. Forest and natural resources need to have sustainable management if they are to be able to be continually used by our generation and future generations. Our personal lives also need to be managed sustainably. This can be by making decisions that will help sustain our immediate surroundings and environment, or it can be by managing our emotional and physical well-being. Sustainable management can be applied to many things, as it can be applied as a literal and an abstract concept. Meaning, depending on what they are applied to the meaning of what it is can change. History Managers' strategies reflect the mindset of the times. This being the case, it has been a problem for the evolution of sustainable management practices for two reasons. The first reason is that sustainable norms are continually changing. For example, things considered unthinkable a few years ago are now standard practices. And the second reason is that in order to practice sustainable management, one has to be forward thinking, not only in the short term, but also in the long term. Management behavior is a reflection of how accepted conceptions of behavior are defined. This means that forces and beliefs outside of the given program push along the management. The manager can take some credit for the cultural changes in his or her program, but overall the organization’s culture reflects dominant conceptions of the public at that time. This is exemplified through the managerial actions taken during the time periods that lead up to the present day. These examples are given below: Industrial environmentalism (1960–1970) This was a time period in which, even though there were outside concerns about the environment, the industries were able to resist pressures and make their own definitions and regulations. Environmentalists were not viewed as credible sources of information during this time and usually discredited. Regulatory environmentalism (1970–1982) The norms of this period radically shifted with the creating of the U.S. Environmental Protection Agency (EPA) in 1970. The EPA became the mediator between the environmentalists and the industry, although the two sides never met. During this period, the environment for the majority of industry and business management teams was only important in terms of compliance with law. In 1974 a conference board survey found that the majority of companies still treated environmental management as a threat. The survey noted a widespread tendency in most of industry to treat pollution control expenditures as non-recoverable investments. According to the consensus environmental protection was considered at best a necessary evil, and at worst a temporary nuisance. Environmentalism as social responsibility (1982–1988) By 1982, the EPA had lost its credibility, but at the same time activism became more influential, and there was an increase in the funding and memberships of major non-governmental organizations (NGOs). Industry gradually became more cooperative with government and new managerial structures were implemented to achieve compliances with regulations. Strategic environmentalism (1988–1993) During this period, industry progressed into a proactive stance on environmental protection. With this attitude, the issue became one in which they felt qualified to manage on their own. Although there was advancement in organizational power, the concern for the environment still kept being pushed down the hierarchy of important things to do. Environmental management as an opportunity (1993–present) In 1995 Harvard professor Michael Porter wrote in the Harvard Business Review that environmental protection was not a threat to the corporate enterprise but rather an opportunity, one that could increase competitive advantage in the marketplace. Before 2000, The companies generally regarded green buildings as interesting experiments but unfeasible projects in the real business world. Since then several factors, including the ones listed below, have caused major shifts in thinking. The creation of reliable building rating and performance measurement systems for new construction and renovation has helped change corporate perceptions about green. In 2000, the Washington D.C.-based United States Green Building Council launched its rigorous Leadership in Energy and Environmental Design (LEED) program. Hundreds of US and international studies have proven the financial advantages of going green: lower utility costs, higher employee productivity. Green building materials, mechanical systems, and furnishings have become more widely available, and prices have dropped considerably. As changes are made to the norms of what is acceptable from a management perspective, more and more it becomes apparent that sustainable management is the new norm of the future. Currently, there are many programs, organizations, communities, and businesses that follow sustainable management plans. These new entities are pressing forward with the help of changing social norms and management initiatives. Management position A manager is a person that is held responsible for the planning of things that will benefit the situation that they are controlling. To be a manager of sustainability, one needs to be a manager that can control issues and plan solutions that will be sustainable, so that what they put into place will be able to continue for future generations. The job of a sustainable manager is like other management positions, but additionally they have to manage systems so that they are able to support and sustain themselves. Whether it is a person that is a manager of groups, business, family, communities, organizations, agriculture, or the environment, they can all use sustainable management to improve their productivity, environment, and atmosphere, among other things. Some practical skills that are needed to be able to perform the job include: Seeing problems/issues Being able to set goals/agendas Planning Skills Creating new ways of doing things (thinking outside the box) Taking action when it is needed Organizational skills Being able to teach, make aware, and train people Ability to make tough decisions Keeping track of progress Taking responsibility Ability to project current issues/ideas/plans into the Future Possessing whole systems thinking Recently, there has even been the addition of new programs in colleges and universities in order to be able to offer Bachelor of Science and Master of Science degrees in Sustainable management. Business In business, time and time again, environmentalists are seen facing off against industry, and there is usually very little "meeting in the middle" or compromises. When these two sides agree to disagree, the result is a more powerful message, and it becomes one that allows more people to understand and embrace. Organizations need to face the fact that the boundaries of accountability are moving fast. The trend towards sustainable management means that organizations are beginning to implement a systems wide approach that links in the various parts of the business with the greater environment at large. As sustainable management institutions adapt, it becomes imperative that they include an image of sustainable responsibility that is projected for the public to see. This is because firms are socially based organizations. But this can be a double edged sword, because sometimes they end up focusing too much on their image rather than actually focusing on implementing what they are trying to project to the public; this is called green washing. It is important that the execution of sustainable management practices is not put aside while the firm tries to appeal to the public with their sustainable management “practices.” Additionally, companies must make the connection between sustainability as a vision and sustainability as a practice. Managers need to think systematically and realistically about the application of traditional business principles to environmental problems. By melding the two concepts together, new ideas of business principles emerge and can enable some companies-those with the right industry structure, competitive position, and managerial skills- to deliver increased value to shareholders while making improvements in their environmental performance. Any corporation can become green on a standard budget. By focusing on the big picture, a company can generate more savings and better performance. By using planning, design, and construction based on sustainable values, sustainable management strives to gain LEED points by reducing footprint of the facility by sustainably planning the site with focus on these three core ideas. To complete a successful green building, or business, the management also applies cost benefit analysis in order to allocate funds appropriately. Business economics The economic system, like all systems, is subject to the laws of thermodynamics, which define the limit at which the Earth can successfully process energy and wastes. Managers need to understand that their values are critical factors in their decisions. Many of current business values are based on unrealistic economic assumptions; adopting new economic models that take the Earth into account in the decision-making process is at the core of sustainable management. This new management addresses the interrelatedness of the ecosystem and the economic system. The strategic vision that is based on core values of the firm guides the firm’s decision-making processes at all levels. Thus, the sustainable management requires finding out what business activities fit into the Earth’s carrying capacity, and also defining the optimal levels of those activities. Sustainability values form the basis of the strategic management, process the costs and benefits of the firm’s operations, and are measured against the survival needs of the planets stakeholders. Sustainability is the core value because it supports a strategic vision of firms in the long term by integrating economic profits with the responsibility to protect the whole environment. Service model Changing industrial processes so that they actually replenish and magnify the stock of natural capital is another component of sustainable management. One way managers have figured out how to do this is by using a service model of business. This focuses on building relationships with customers, instead of focusing on making and selling products. This type of model represents a fundamental change in the way businesses behave. It allows for managers to be aware of the lifecycle of their products by leaving the responsibility up to the company to take care of the product throughout the life cycle. The service model, because the product is the responsibility of the business, creates an avenue in which the managers can see ways in which they can reduce the use of resources through recycling and product construction. Communities For communities to be able to improve, sustainable management needs to be in practice. If a community relies on the resources that are in the surrounding area, then they need to be used in a sustainable manner to insure the indefinite supply of the resources. A community needs to work together to be able to be productive, and when there is a need to get things done, management needs to take the lead. If sustainable management is in practice in a community, then people will want to stay in that community, and other people will realize the success, and they will also want to live in a similar environment, as their own unsustainable towns fail. Part of a sustainable management system in a community is the education, the cooperation, and the responsiveness of the people that live in the community. There are new ideals to how a community can be sustainable. This can include urban planning, which allow people to move about a city that are more sustainable for the environment. If management plans a community that allows for people to move without cars, it helps make a community sustainable by increasing mass transit or other modes of transportation. People would spend less time in traffic while improving the environment, and on an occasions exercise. Sustainable management provides plans that can improve multiple parts of people lives, environment, and future generations. If a community sets goals, then people are more likely to reduce energy, water, and waste, but a community cannot set goals unless they have the management in place to set goals. A part of sustainable management for a community is communicating the ideals and plans for an area to the people that will be carrying out the plan. It is important to note that sustainable management is not sustainable if the person that is managing a situation is not communicating what needs to be improved, how it should be improved, why it is important to them, and how they are involved it in the process. Personal life For a person to be responsible for their action is a part of managing, and that is part of being managed sustainable. To be able to manage oneself sustainable there are many factors to consider, because to be able to manage oneself a person needs to be able to see what they are doing unsustainable, and how to become sustainable. By using plastic bags at a check out line is unsustainable because it creates pollutants, but using reusable biodegradable bags can resolve the problem. This is not only environmentally sustainable, but it also improves the physical and mental sustainability of the person that uses the reusable bags. It is physical improvement because people do not have to live with the countless plastic bags on the Earth and the pollution that comes with it. It is also an improvement to mental sustainability, because the person that uses the reusable bags has feeling of accomplishment that comes from doing the right thing. Deciding to buy local food to make the community stronger through community sustainable management, can also be emotionally, environmentally, and physically rewarding. In Figure 1 Mckenzie shows how a person can look at a behavior that they are doing and determine if it is sustainable or not, and what they could replace the bad behavior with. Education of an individual would be the first step to deciding to take a step towards managing their lives sustainable. To manage a person life the benefits needs to be high and the barriers low. Good managing would come up with a competing behavior that has no barriers to it. To come up with a Competing behavior that does not have a barrier to it would involve good problem solving. Figure 2 Mckenzie is an example of what a person might try to change in their life to make it more sustainable. Walking instead of taking the taxi helps the environment, but it also loses time spent with family. The bus is in the middle of walking and taking a taxi, but another option that is not on the list is riding a bike. Good sustainable management would include all the options that are possible, and new options that were not available before. These figures are tools that can be used in helping people manage their lives sustainably, but there are other ways to think about their lives to become more sustainable. Forests There are very practical needs for sustainable management of forest. Since forests provide many as per as resources to the people, and to the world, management of the forests are critical to keep those resources available. To be able to manage a forest, knowledge of how the natural systems work is needed. If a manager knows how the natural system works, then when manager of the forest makes plans how the resources are to remove from the forest, the manager will know how the resources can be removed without damaging the forest. Since many forests are under management of the government that is in the region, the forest are not truly functioning how the ecosystem was naturally developed, and how it is meant to be. An example is the pine flatwoods in Florida. To be able to maintain that ecosystem frequent burnings of the forest needs to happen. Fires are a natural part of the ecosystem, but since wild fires can spread to communities near the forest, control of the wild fires is requested from the communities. To maintain flatwoods forest control burning or prescribe burning is part of the management to sustain the forest.

Sociology

Sociology is the scientific study of human society that focuses on society, human social behavior, patterns of social relationships, social interaction, and aspects of culture associated with everyday life. Regarded as a part of both the social sciences and humanities, sociology uses various methods of empirical investigation and critical analysis to develop a body of knowledge about social order and social change. Sociological subject matter ranges from micro-level analyses of individual interaction and agency to macro-level analyses of social systems and social structure. Applied sociological research may be applied directly to social policy and welfare, whereas theoretical approaches may focus on the understanding of social processes and phenomenological method. Traditional focuses of sociology include social stratification, social class, social mobility, religion, secularization, law, sexuality, gender, and deviance. Recent studies have added socio-technical aspects of the digital divide as a new focus. As all spheres of human activity are affected by the interplay between social structure and individual agency, sociology has gradually expanded its focus to other subjects and institutions, such as health and the institution of medicine; economy; military; punishment and systems of control; the Internet; sociology of education; social capital; and the role of social activity in the development of scientific knowledge. The range of social scientific methods has also expanded, as social researchers draw upon a variety of qualitative and quantitative techniques. The linguistic and cultural turns of the mid-20th century, especially, have led to increasingly interpretative, hermeneutic, and philosophical approaches towards the analysis of society. Conversely, the turn of the 21st century has seen the rise of new analytically, mathematically, and computationally rigorous techniques, such as agent-based modelling and social network analysis. Social research has influence throughout various industries and sectors of life, such as among politicians, policy makers, and legislators; educators; planners; administrators; developers; business magnates and managers; social workers; non-governmental organizations; and non-profit organizations, as well as individuals interested in resolving social issues in general. History Sociological reasoning predates the foundation of the discipline itself. Social analysis has origins in the common stock of universal, global knowledge and philosophy, having been carried out from as far back as the time of old comic poetry which features social and political criticism, and ancient Greek philosophers Socrates, Plato, and Aristotle. For instance, the origin of the survey can be traced back to at least the Domesday Book in 1086, while ancient philosophers such as Confucius wrote about the importance of social roles. Medieval Arabic writings encompass a rich tradition that unveils early insights into the field of sociology. Some sources consider Ibn Khaldun, a 14th-century Muslim scholar from Tunisia, to have been the father of sociology, although there is no reference to his work in the writings of European contributors to modern sociology. Khaldun's Muqaddimah was considered to be amongst the first works to advance social-scientific reasoning on social cohesion and social conflict. Etymology The word sociology derives part of its name from the Latin word socius ('companion' or 'fellowship'). The suffix -logy ('the study of') comes from that of the Greek -λογία, derived from λόγος (, 'word' or 'knowledge'). The term sociology was first coined in 1780 by the French essayist Emmanuel-Joseph Sieyès in an unpublished manuscript. Sociology was later defined independently by French philosopher of science Auguste Comte (1798–1857) in 1838 as a new way of looking at society. Comte had earlier used the term social physics, but it had been subsequently appropriated by others, most notably the Belgian statistician Adolphe Quetelet. Comte endeavored to unify history, psychology, and economics through the scientific understanding of social life. Writing shortly after the malaise of the French Revolution, he proposed that social ills could be remedied through sociological positivism, an epistemological approach outlined in the Course in Positive Philosophy (1830–1842), later included in A General View of Positivism (1848). Comte believed a positivist stage would mark the final era in the progression of human understanding, after conjectural theological and metaphysical phases. In observing the circular dependence of theory and observation in science, and having classified the sciences, Comte may be regarded as the first philosopher of science in the modern sense of the term. Marx Both Comte and Karl Marx set out to develop scientifically justified systems in the wake of European industrialization and secularization, informed by various key movements in the philosophies of history and science. Marx rejected Comtean positivism but in attempting to develop a "science of society" nevertheless came to be recognized as a founder of sociology as the word gained wider meaning. For Isaiah Berlin, even though Marx did not consider himself to be a sociologist, he may be regarded as the "true father" of modern sociology, "in so far as anyone can claim the title."To have given clear and unified answers in familiar empirical terms to those theoretical questions which most occupied men's minds at the time, and to have deduced from them clear practical directives without creating obviously artificial links between the two, was the principal achievement of Marx's theory. The sociological treatment of historical and moral problems, which Comte and after him, Spencer and Taine, had discussed and mapped, became a precise and concrete study only when the attack of militant Marxism made its conclusions a burning issue, and so made the search for evidence more zealous and the attention to method more intense. Spencer Herbert Spencer was one of the most popular and influential 19th-century sociologists. It is estimated that he sold one million books in his lifetime, far more than any other sociologist at the time. So strong was his influence that many other 19th-century thinkers, including Émile Durkheim, defined their ideas in relation to his. Durkheim's Division of Labour in Society is to a large extent an extended debate with Spencer from whose sociology Durkheim borrowed extensively. Also a notable biologist, Spencer coined the term survival of the fittest. While Marxian ideas defined one strand of sociology, Spencer was a critic of socialism, as well as a strong advocate for a laissez-faire style of government. His ideas were closely observed by conservative political circles, especially in the United States and England. Foundations of the academic discipline The first formal Department of Sociology in the world was established in 1892 by Albion Small—from the invitation of William Rainey Harper—at the University of Chicago. The American Journal of Sociology was founded shortly thereafter in 1895 by Small as well. The institutionalization of sociology as an academic discipline, however, was chiefly led by Émile Durkheim, who developed positivism as a foundation for practical social research. While Durkheim rejected much of the detail of Comte's philosophy, he retained and refined its method, maintaining that the social sciences are a logical continuation of the natural ones into the realm of human activity, and insisting that they may retain the same objectivity, rationalism, and approach to causality. Durkheim set up the first European department of sociology at the University of Bordeaux in 1895, publishing his Rules of the Sociological Method (1895). For Durkheim, sociology could be described as the "science of institutions, their genesis and their functioning." Durkheim's monograph Suicide (1897) is considered a seminal work in statistical analysis by contemporary sociologists. Suicide is a case study of variations in suicide rates among Catholic and Protestant populations, and served to distinguish sociological analysis from psychology or philosophy. It also marked a major contribution to the theoretical concept of structural functionalism. By carefully examining suicide statistics in different police districts, he attempted to demonstrate that Catholic communities have a lower suicide rate than that of Protestants, something he attributed to social (as opposed to individual or psychological) causes. He developed the notion of objective social facts to delineate a unique empirical object for the science of sociology to study. Through such studies he posited that sociology would be able to determine whether any given society is healthy or pathological, and seek social reform to negate organic breakdown, or "social anomie". Sociology quickly evolved as an academic response to the perceived challenges of modernity, such as industrialization, urbanization, secularization, and the process of rationalization. The field predominated in continental Europe, with British anthropology and statistics generally following on a separate trajectory. By the turn of the 20th century, however, many theorists were active in the English-speaking world. Few early sociologists were confined strictly to the subject, interacting also with economics, jurisprudence, psychology and philosophy, with theories being appropriated in a variety of different fields. Since its inception, sociological epistemology, methods, and frames of inquiry, have significantly expanded and diverged. Durkheim, Marx, and the German theorist Max Weber are typically cited as the three principal architects of sociology. Herbert Spencer, William Graham Sumner, Lester F. Ward, W. E. B. Du Bois, Vilfredo Pareto, Alexis de Tocqueville, Werner Sombart, Thorstein Veblen, Ferdinand Tönnies, Georg Simmel, Jane Addams and Karl Mannheim are often included on academic curricula as founding theorists. Curricula also may include Charlotte Perkins Gilman, Marianne Weber, Harriet Martineau, and Friedrich Engels as founders of the feminist tradition in sociology. Each key figure is associated with a particular theoretical perspective and orientation. Further developments The first college course entitled "Sociology" was taught in the United States at Yale in 1875 by William Graham Sumner. In 1883, Lester F. Ward, who later became the first president of the American Sociological Association (ASA), published Dynamic Sociology—Or Applied social science as based upon statical sociology and the less complex sciences, attacking the laissez-faire sociology of Herbert Spencer and Sumner. Ward's 1,200-page book was used as core material in many early American sociology courses. In 1890, the oldest continuing American course in the modern tradition began at the University of Kansas, lectured by Frank W. Blackmar. The Department of Sociology at the University of Chicago was established in 1892 by Albion Small, who also published the first sociology textbook: An introduction to the study of society. George Herbert Mead and Charles Cooley, who had met at the University of Michigan in 1891 (along with John Dewey), moved to Chicago in 1894. Their influence gave rise to social psychology and the symbolic interactionism of the modern Chicago School. The American Journal of Sociology was founded in 1895, followed by the ASA in 1905. The sociological canon of classics with Durkheim and Max Weber at the top owes its existence in part to Talcott Parsons, who is largely credited with introducing both to American audiences. Parsons consolidated the sociological tradition and set the agenda for American sociology at the point of its fastest disciplinary growth. Sociology in the United States was less historically influenced by Marxism than its European counterpart, and to this day broadly remains more statistical in its approach. The first sociology department established in the United Kingdom was at the London School of Economics and Political Science (home of the British Journal of Sociology) in 1904. Leonard Trelawny Hobhouse and Edvard Westermarck became the lecturers in the discipline at the University of London in 1907. Harriet Martineau, an English translator of Comte, has been cited as the first female sociologist. In 1909, the German Sociological Association was founded by Ferdinand Tönnies and Max Weber, among others. Weber established the first department in Germany at the Ludwig Maximilian University of Munich in 1919, having presented an influential new antipositivist sociology. In 1920, Florian Znaniecki set up the first department in Poland. The Institute for Social Research at the University of Frankfurt (later to become the Frankfurt School of critical theory) was founded in 1923. International co-operation in sociology began in 1893, when René Worms founded the Institut International de Sociologie, an institution later eclipsed by the much larger International Sociological Association (ISA), founded in 1949. Theoretical traditions Positivism and anti-positivism Positivism The overarching methodological principle of positivism is to conduct sociology in broadly the same manner as natural science. An emphasis on empiricism and the scientific method is sought to provide a tested foundation for sociological research based on the assumption that the only authentic knowledge is scientific knowledge, and that such knowledge can only arrive by positive affirmation through scientific methodology. The term has long since ceased to carry this meaning; there are no fewer than twelve distinct epistemologies that are referred to as positivism. Many of these approaches do not self-identify as "positivist", some because they themselves arose in opposition to older forms of positivism, and some because the label has over time become a pejorative term by being mistakenly linked with a theoretical empiricism. The extent of antipositivist criticism has also diverged, with many rejecting the scientific method and others only seeking to amend it to reflect 20th-century developments in the philosophy of science. However, positivism (broadly understood as a scientific approach to the study of society) remains dominant in contemporary sociology, especially in the United States. Loïc Wacquant distinguishes three major strains of positivism: Durkheimian, Logical, and Instrumental. None of these are the same as that set forth by Comte, who was unique in advocating such a rigid (and perhaps optimistic) version. While Émile Durkheim rejected much of the detail of Comte's philosophy, he retained and refined its method. Durkheim maintained that the social sciences are a logical continuation of the natural ones into the realm of human activity, and insisted that they should retain the same objectivity, rationalism, and approach to causality. He developed the notion of objective sui generis "social facts" to serve as unique empirical objects for the science of sociology to study. The variety of positivism that remains dominant today is termed instrumental positivism. This approach eschews epistemological and metaphysical concerns (such as the nature of social facts) in favour of methodological clarity, replicability, reliability and validity. This positivism is more or less synonymous with quantitative research, and so only resembles older positivism in practice. Since it carries no explicit philosophical commitment, its practitioners may not belong to any particular school of thought. Modern sociology of this type is often credited to Paul Lazarsfeld, who pioneered large-scale survey studies and developed statistical techniques for analysing them. This approach lends itself to what Robert K. Merton called middle-range theory: abstract statements that generalize from segregated hypotheses and empirical regularities rather than starting with an abstract idea of a social whole. Antipositivism The German philosopher Hegel criticised traditional empiricist epistemology, which he rejected as uncritical, and determinism, which he viewed as overly mechanistic. Karl Marx's methodology borrowed from Hegelian dialecticism but also a rejection of positivism in favour of critical analysis, seeking to supplement the empirical acquisition of "facts" with the elimination of illusions. He maintained that appearances need to be critiqued rather than simply documented. Early hermeneuticians such as Wilhelm Dilthey pioneered the distinction between natural and social science ('Geisteswissenschaft'). Various neo-Kantian philosophers, phenomenologists and human scientists further theorized how the analysis of the social world differs to that of the natural world due to the irreducibly complex aspects of human society, culture, and being. In the Italian context of development of social sciences and of sociology in particular, there are oppositions to the first foundation of the discipline, sustained by speculative philosophy in accordance with the antiscientific tendencies matured by critique of positivism and evolutionism, so a tradition Progressist struggles to establish itself. At the turn of the 20th century, the first generation of German sociologists formally introduced methodological anti-positivism, proposing that research should concentrate on human cultural norms, values, symbols, and social processes viewed from a resolutely subjective perspective. Max Weber argued that sociology may be loosely described as a science as it is able to identify causal relationships of human "social action"—especially among "ideal types", or hypothetical simplifications of complex social phenomena. As a non-positivist, however, Weber sought relationships that are not as "historical, invariant, or generalisable" as those pursued by natural scientists. Fellow German sociologist, Ferdinand Tönnies, theorised on two crucial abstract concepts with his work on "gemeinschaft and gesellschaft". Tönnies marked a sharp line between the realm of concepts and the reality of social action: the first must be treated axiomatically and in a deductive way ("pure sociology"), whereas the second empirically and inductively ("applied sociology"). Both Weber and Georg Simmel pioneered the "Verstehen" (or 'interpretative') method in social science; a systematic process by which an outside observer attempts to relate to a particular cultural group, or indigenous people, on their own terms and from their own point of view. Through the work of Simmel, in particular, sociology acquired a possible character beyond positivist data-collection or grand, deterministic systems of structural law. Relatively isolated from the sociological academy throughout his lifetime, Simmel presented idiosyncratic analyses of modernity more reminiscent of the phenomenological and existential writers than of Comte or Durkheim, paying particular concern to the forms of, and possibilities for, social individuality. His sociology engaged in a neo-Kantian inquiry into the limits of perception, asking 'What is society?' in a direct allusion to Kant's question 'What is nature?' Classical theory The contemporary discipline of sociology is theoretically multi-paradigmatic in line with the contentions of classical social theory. Randall Collins' well-cited survey of sociological theory retroactively labels various theorists as belonging to four theoretical traditions: Functionalism, Conflict, Symbolic Interactionism, and Utilitarianism. Accordingly, modern sociological theory predominantly descends from functionalist (Durkheim) and conflict (Marx and Weber) approaches to social structure, as well as from symbolic-interactionist approaches to social interaction, such as micro-level structural (Simmel) and pragmatist (Mead, Cooley) perspectives. Utilitarianism (also known as rational choice or social exchange), although often associated with economics, is an established tradition within sociological theory. Lastly, as argued by Raewyn Connell, a tradition that is often forgotten is that of Social Darwinism, which applies the logic of Darwinian biological evolution to people and societies. This tradition often aligns with classical functionalism, and was once the dominant theoretical stance in American sociology, from , associated with several founders of sociology, primarily Herbert Spencer, Lester F. Ward, and William Graham Sumner. Contemporary sociological theory retains traces of each of these traditions and they are by no means mutually exclusive. Functionalism A broad historical paradigm in both sociology and anthropology, functionalism addresses the social structure—referred to as "social organization" by the classical theorists—with respect to the whole as well as the necessary function of the whole's constituent elements. A common analogy (popularized by Herbert Spencer) is to regard norms and institutions as 'organs' that work towards the proper functioning of the entire 'body' of society. The perspective was implicit in the original sociological positivism of Comte but was theorized in full by Durkheim, again with respect to observable, structural laws. Functionalism also has an anthropological basis in the work of theorists such as Marcel Mauss, Bronisław Malinowski, and Radcliffe-Brown. It is in the latter's specific usage that the prefix "structural" emerged. Classical functionalist theory is generally united by its tendency towards biological analogy and notions of social evolutionism, in that the basic form of society would increase in complexity and those forms of social organization that promoted solidarity would eventually overcome social disorganization. As Giddens states:Functionalist thought, from Comte onwards, has looked particularly towards biology as the science providing the closest and most compatible model for social science. Biology has been taken to provide a guide to conceptualizing the structure and the function of social systems and to analyzing processes of evolution via mechanisms of adaptation. Functionalism strongly emphasizes the pre-eminence of the social world over its individual parts (i.e. its constituent actors, human subjects). Conflict theory Functionalist theories emphasize "cohesive systems" and are often contrasted with "conflict theories", which critique the overarching socio-political system or emphasize the inequality between particular groups. The following quotes from Durkheim and Marx epitomize the political, as well as theoretical, disparities, between functionalist and conflict thought respectively: Symbolic interactionism Symbolic interaction—often associated with interactionism, phenomenology, dramaturgy, interpretivism—is a sociological approach that places emphasis on subjective meanings and the empirical unfolding of social processes, generally accessed through micro-analysis. This tradition emerged in the Chicago School of the 1920s and 1930s, which, prior to World War II, "had been the center of sociological research and graduate study." The approach focuses on creating a framework for building a theory that sees society as the product of the everyday interactions of individuals. Society is nothing more than the shared reality that people construct as they interact with one another. This approach sees people interacting in countless settings using symbolic communications to accomplish the tasks at hand. Therefore, society is a complex, ever-changing mosaic of subjective meanings. Some critics of this approach argue that it only looks at what is happening in a particular social situation, and disregards the effects that culture, race or gender (i.e. social-historical structures) may have in that situation. Some important sociologists associated with this approach include Max Weber, George Herbert Mead, Erving Goffman, George Homans, and Peter Blau. It is also in this tradition that the radical-empirical approach of ethnomethodology emerges from the work of Harold Garfinkel. Utilitarianism Utilitarianism is often referred to as exchange theory or rational choice theory in the context of sociology. This tradition tends to privilege the agency of individual rational actors and assumes that within interactions individuals always seek to maximize their own self-interest. As argued by Josh Whitford, rational actors are assumed to have four basic elements: "a knowledge of alternatives;" "a knowledge of, or beliefs about the consequences of the various alternatives;" "an ordering of preferences over outcomes;" and "a decision rule, to select among the possible alternatives" Exchange theory is specifically attributed to the work of George C. Homans, Peter Blau and Richard Emerson. Organizational sociologists James G. March and Herbert A. Simon noted that an individual's rationality is bounded by the context or organizational setting. The utilitarian perspective in sociology was, most notably, revitalized in the late 20th century by the work of former ASA president James Coleman. 20th-century social theory Following the decline of theories of sociocultural evolution in the United States, the interactionist thought of the Chicago School dominated American sociology. As Anselm Strauss describes, "we didn't think symbolic interaction was a perspective in sociology; we thought it was sociology." Moreover, philosophical and psychological pragmatism grounded this tradition. After World War II, mainstream sociology shifted to the survey-research of Paul Lazarsfeld at Columbia University and the general theorizing of Pitirim Sorokin, followed by Talcott Parsons at Harvard University. Ultimately, "the failure of the Chicago, Columbia, and Wisconsin [sociology] departments to produce a significant number of graduate students interested in and committed to general theory in the years 1936–45 was to the advantage of the Harvard department." As Parsons began to dominate general theory, his work primarily referenced European sociology—almost entirely omitting citations of both the American tradition of sociocultural-evolution as well as pragmatism. In addition to Parsons' revision of the sociological canon (which included Marshall, Pareto, Weber and Durkheim), the lack of theoretical challenges from other departments nurtured the rise of the Parsonian structural-functionalist movement, which reached its crescendo in the 1950s, but by the 1960s was in rapid decline. By the 1980s, most functionalist perspectives in Europe had broadly been replaced by conflict-oriented approaches, and to many in the discipline, functionalism was considered "as dead as a dodo:" According to Giddens:The orthodox consensus terminated in the late 1960s and 1970s as the middle ground shared by otherwise competing perspectives gave way and was replaced by a baffling variety of competing perspectives. This third 'generation' of social theory includes phenomenologically inspired approaches, critical theory, ethnomethodology, symbolic interactionism, structuralism, post-structuralism, and theories written in the tradition of hermeneutics and ordinary language philosophy. Pax Wisconsana While some conflict approaches also gained popularity in the United States, the mainstream of the discipline instead shifted to a variety of empirically oriented middle-range theories with no single overarching, or "grand", theoretical orientation. John Levi Martin refers to this "golden age of methodological unity and theoretical calm" as the Pax Wisconsana, as it reflected the composition of the sociology department at the University of Wisconsin–Madison: numerous scholars working on separate projects with little contention. Omar Lizardo describes the pax wisconsana as "a Midwestern flavored, Mertonian resolution of the theory/method wars in which [sociologists] all agreed on at least two working hypotheses: (1) grand theory is a waste of time; [and] (2) good theory has to be good to think with or goes in the trash bin." Despite the aversion to grand theory in the latter half of the 20th century, several new traditions have emerged that propose various syntheses: structuralism, post-structuralism, cultural sociology and systems theory. Some sociologists have called for a return to 'grand theory' to combat the rise of scientific and pragmatist influences within the tradition of sociological thought (see Duane Rousselle). Structuralism The structuralist movement originated primarily from the work of Durkheim as interpreted by two European scholars: Anthony Giddens, a sociologist, whose theory of structuration draws on the linguistic theory of Ferdinand de Saussure; and Claude Lévi-Strauss, an anthropologist. In this context, 'structure' does not refer to 'social structure', but to the semiotic understanding of human culture as a system of signs. One may delineate four central tenets of structuralism: Structure is what determines the structure of a whole. Structuralists believe that every system has a structure. Structuralists are interested in 'structural' laws that deal with coexistence rather than changes. Structures are the 'real things' beneath the surface or the appearance of meaning. The second tradition of structuralist thought, contemporaneous with Giddens, emerges from the American School of social network analysis in the 1970s and 1980s, spearheaded by the Harvard Department of Social Relations led by Harrison White and his students. This tradition of structuralist thought argues that, rather than semiotics, social structure is networks of patterned social relations. And, rather than Levi-Strauss, this school of thought draws on the notions of structure as theorized by Levi-Strauss' contemporary anthropologist, Radcliffe-Brown. Some refer to this as "network structuralism", and equate it to "British structuralism" as opposed to the "French structuralism" of Levi-Strauss. Post-structuralism Post-structuralist thought has tended to reject 'humanist' assumptions in the construction of social theory. Michel Foucault provides an important critique in his Archaeology of the Human Sciences, though Habermas (1986) and Rorty (1986) have both argued that Foucault merely replaces one such system of thought with another. The dialogue between these intellectuals highlights a trend in recent years for certain schools of sociology and philosophy to intersect. The anti-humanist position has been associated with "postmodernism", a term used in specific contexts to describe an era or phenomena, but occasionally construed as a method. Central theoretical problems Overall, there is a strong consensus regarding the central problems of sociological theory, which are largely inherited from the classical theoretical traditions. This consensus is: how to link, transcend or cope with the following "big three" dichotomies: subjectivity and objectivity, which deal with knowledge; structure and agency, which deal with action; and synchrony and diachrony, which deal with time. Lastly, sociological theory often grapples with the problem of integrating or transcending the divide between micro, meso, and macro-scale social phenomena, which is a subset of all three central problems. Subjectivity and objectivity The problem of subjectivity and objectivity can be divided into two parts: a concern over the general possibilities of social actions, and the specific problem of social scientific knowledge. In the former, the subjective is often equated (though not necessarily) with the individual, and the individual's intentions and interpretations of the objective. The objective is often considered any public or external action or outcome, on up to society writ large. A primary question for social theorists, then, is how knowledge reproduces along the chain of subjective-objective-subjective, that is to say: how is intersubjectivity achieved? While, historically, qualitative methods have attempted to tease out subjective interpretations, quantitative survey methods also attempt to capture individual subjectivities. Qualitative methods take an approach to objective description known as in situ, meaning that descriptions must have appropriate contextual information to understand the information. The latter concern with scientific knowledge results from the fact that a sociologist is part of the very object they seek to explain, as Bourdieu explains: Structure and agency Structure and agency, sometimes referred to as determinism versus voluntarism, form an enduring ontological debate in social theory: "Do social structures determine an individual's behaviour or does human agency?" In this context, agency refers to the capacity of individuals to act independently and make free choices, whereas structure relates to factors that limit or affect the choices and actions of individuals (e.g. social class, religion, gender, ethnicity, etc.). Discussions over the primacy of either structure or agency relate to the core of sociological epistemology (i.e. "what is the social world made of?", "what is a cause in the social world, and what is an effect?"). A perennial question within this debate is that of "social reproduction": how are structures (specifically, structures producing inequality) reproduced through the choices of individuals? Synchrony and diachrony Synchrony and diachrony (or statics and dynamics) within social theory are terms that refer to a distinction that emerged through the work of Levi-Strauss who inherited it from the linguistics of Ferdinand de Saussure. Synchrony slices moments of time for analysis, thus it is an analysis of static social reality. Diachrony, on the other hand, attempts to analyse dynamic sequences. Following Saussure, synchrony would refer to social phenomena as a static concept like a language, while diachrony would refer to unfolding processes like actual speech. In Anthony Giddens' introduction to Central Problems in Social Theory, he states that, "in order to show the interdependence of action and structure…we must grasp the time space relations inherent in the constitution of all social interaction." And like structure and agency, time is integral to discussion of social reproduction. In terms of sociology, historical sociology is often better positioned to analyse social life as diachronic, while survey research takes a snapshot of social life and is thus better equipped to understand social life as synchronized. Some argue that the synchrony of social structure is a methodological perspective rather than an ontological claim. Nonetheless, the problem for theory is how to integrate the two manners of recording and thinking about social data. Research methodology Sociological research methods may be divided into two broad, though often supplementary, categories: Qualitative designs emphasize understanding of social phenomena through direct observation, communication with participants, or analysis of texts, and may stress contextual and subjective accuracy over generality. Quantitative designs approach social phenomena through quantifiable evidence, and often rely on statistical analysis of many cases (or across intentionally designed treatments in an experiment) to establish valid and reliable general claims. Sociologists are often divided into camps of support for particular research techniques. These disputes relate to the epistemological debates at the historical core of social theory. While very different in many aspects, both qualitative and quantitative approaches involve a systematic interaction between theory and data. Quantitative methodologies hold the dominant position in sociology, especially in the United States. In the discipline's two most cited journals, quantitative articles have historically outnumbered qualitative ones by a factor of two. (Most articles published in the largest British journal, on the other hand, are qualitative.) Most textbooks on the methodology of social research are written from the quantitative perspective, and the very term "methodology" is often used synonymously with "statistics". Practically all sociology PhD programmes in the United States require training in statistical methods. The work produced by quantitative researchers is also deemed more 'trustworthy' and 'unbiased' by the general public, though this judgment continues to be challenged by antipositivists. The choice of method often depends largely on what the researcher intends to investigate. For example, a researcher concerned with drawing a statistical generalization across an entire population may administer a survey questionnaire to a representative sample population. By contrast, a researcher who seeks full contextual understanding of an individual's social actions may choose ethnographic participant observation or open-ended interviews. Studies will commonly combine, or 'triangulate', quantitative and qualitative methods as part of a 'multi-strategy' design. For instance, a quantitative study may be performed to obtain statistical patterns on a target sample, and then combined with a qualitative interview to determine the play of agency. Sampling Quantitative methods are often used to ask questions about a population that is very large, making a census or a complete enumeration of all the members in that population infeasible. A 'sample' then forms a manageable subset of a population. In quantitative research, statistics are used to draw inferences from this sample regarding the population as a whole. The process of selecting a sample is referred to as 'sampling'. While it is usually best to sample randomly, concern with differences between specific subpopulations sometimes calls for stratified sampling. Conversely, the impossibility of random sampling sometimes necessitates nonprobability sampling, such as convenience sampling or snowball sampling. Methods The following list of research methods is neither exclusive nor exhaustive: Archival research (or the Historical method): Draws upon the secondary data located in historical archives and records, such as biographies, memoirs, journals, and so on. Content analysis: The content of interviews and other texts is systematically analysed. Often data is 'coded' as a part of the 'grounded theory' approach using qualitative data analysis (QDA) software, such as Atlas.ti, MAXQDA, NVivo, or QDA Miner. Experimental research: The researcher isolates a single social process and reproduces it in a laboratory (for example, by creating a situation where unconscious sexist judgements are possible), seeking to determine whether or not certain social variables can cause, or depend upon, other variables (for instance, seeing if people's feelings about traditional gender roles can be manipulated by the activation of contrasting gender stereotypes). Participants are randomly assigned to different groups that either serve as controls—acting as reference points because they are tested with regard to the dependent variable, albeit without having been exposed to any independent variables of interest—or receive one or more treatments. Randomization allows the researcher to be sure that any resulting differences between groups are the result of the treatment. Longitudinal study: An extensive examination of a specific person or group over a long period of time. Observation: Using data from the senses, the researcher records information about social phenomenon or behaviour. Observation techniques may or may not feature participation. In participant observation, the researcher goes into the field (e.g. a community or a place of work), and participates in the activities of the field for a prolonged period of time in order to acquire a deep understanding of it. Data acquired through these techniques may be analysed either quantitatively or qualitatively. In the observation research, a sociologist might study global warming in some part of the world that is less populated. Program Evaluation is a systematic method for collecting, analyzing, and using information to answer questions about projects, policies and programs, particularly about their effectiveness and efficiency. In both the public and private sectors, stakeholders often want to know whether the programs they are funding, implementing, voting for, or objecting to are producing the intended effect. While program evaluation first focuses on this definition, important considerations often include how much the program costs per participant, how the program could be improved, whether the program is worthwhile, whether there are better alternatives, if there are unintended outcomes, and whether the program goals are appropriate and useful. Survey research: The researcher gathers data using interviews, questionnaires, or similar feedback from a set of people sampled from a particular population of interest. Survey items from an interview or questionnaire may be open-ended or closed-ended. Data from surveys is usually analysed statistically on a computer. Computational sociology Sociologists increasingly draw upon computationally intensive methods to analyse and model social phenomena. Using computer simulations, artificial intelligence, text mining, complex statistical methods, and new analytic approaches like social network analysis and social sequence analysis, computational sociology develops and tests theories of complex social processes through bottom-up modelling of social interactions. Although the subject matter and methodologies in social science differ from those in natural science or computer science, several of the approaches used in contemporary social simulation originated from fields such as physics and artificial intelligence. By the same token, some of the approaches that originated in computational sociology have been imported into the natural sciences, such as measures of network centrality from the fields of social network analysis and network science. In relevant literature, computational sociology is often related to the study of social complexity. Social complexity concepts such as complex systems, non-linear interconnection among macro and micro process, and emergence, have entered the vocabulary of computational sociology. A practical and well-known example is the construction of a computational model in the form of an "artificial society", by which researchers can analyse the structure of a social system. Subfields Culture Sociologists' approach to culture can be divided into "sociology of culture" and "cultural sociology"—terms which are similar, though not entirely interchangeable. Sociology of culture is an older term, and considers some topics and objects as more or less "cultural" than others. Conversely, cultural sociology sees all social phenomena as inherently cultural. Sociology of culture often attempts to explain certain cultural phenomena as a product of social processes, while cultural sociology sees culture as a potential explanation of social phenomena. For Simmel, culture referred to "the cultivation of individuals through the agency of external forms which have been objectified in the course of history." While early theorists such as Durkheim and Mauss were influential in cultural anthropology, sociologists of culture are generally distinguished by their concern for modern (rather than primitive or ancient) society. Cultural sociology often involves the hermeneutic analysis of words, artefacts and symbols, or ethnographic interviews. However, some sociologists employ historical-comparative or quantitative techniques in the analysis of culture, Weber and Bourdieu for instance. The subfield is sometimes allied with critical theory in the vein of Theodor W. Adorno, Walter Benjamin, and other members of the Frankfurt School. Loosely distinct from the sociology of culture is the field of cultural studies. Birmingham School theorists such as Richard Hoggart and Stuart Hall questioned the division between "producers" and "consumers" evident in earlier theory, emphasizing the reciprocity in the production of texts. Cultural Studies aims to examine its subject matter in terms of cultural practices and their relation to power. For example, a study of a subculture (e.g. white working class youth in London) would consider the social practices of the group as they relate to the dominant class. The "cultural turn" of the 1960s ultimately placed culture much higher on the sociological agenda. Art, music and literature Sociology of literature, film, and art is a subset of the sociology of culture. This field studies the social production of artistic objects and its social implications. A notable example is Pierre Bourdieu's Les Règles de L'Art: Genèse et Structure du Champ Littéraire (1992). None of the founding fathers of sociology produced a detailed study of art, but they did develop ideas that were subsequently applied to literature by others. Marx's theory of ideology was directed at literature by Pierre Macherey, Terry Eagleton and Fredric Jameson. Weber's theory of modernity as cultural rationalization, which he applied to music, was later applied to all the arts, literature included, by Frankfurt School writers such as Theodor Adorno and Jürgen Habermas. Durkheim's view of sociology as the study of externally defined social facts was redirected towards literature by Robert Escarpit. Bourdieu's own work is clearly indebted to Marx, Weber and Durkheim. Criminality, deviance, law and punishment Criminologists analyse the nature, causes, and control of criminal activity, drawing upon methods across sociology, psychology, and the behavioural sciences. The sociology of deviance focuses on actions or behaviours that violate norms, including both infringements of formally enacted rules (e.g., crime) and informal violations of cultural norms. It is the remit of sociologists to study why these norms exist; how they change over time; and how they are enforced. The concept of social disorganization is when the broader social systems leads to violations of norms. For instance, Robert K. Merton produced a typology of deviance, which includes both individual and system level causal explanations of deviance. Sociology of law The study of law played a significant role in the formation of classical sociology. Durkheim famously described law as the "visible symbol" of social solidarity. The sociology of law refers to both a sub-discipline of sociology and an approach within the field of legal studies. Sociology of law is a diverse field of study that examines the interaction of law with other aspects of society, such as the development of legal institutions and the effect of laws on social change and vice versa. For example, an influential recent work in the field relies on statistical analyses to argue that the increase in incarceration in the US over the last 30 years is due to changes in law and policing and not to an increase in crime; and that this increase has significantly contributed to the persistence of racial stratification. Communications and information technologies The sociology of communications and information technologies includes "the social aspects of computing, the Internet, new media, computer networks, and other communication and information technologies." Internet and digital media The Internet is of interest to sociologists in various ways, most practically as a tool for research and as a discussion platform. The sociology of the Internet in the broad sense concerns the analysis of online communities (e.g. newsgroups, social networking sites) and virtual worlds, meaning that there is often overlap with community sociology. Online communities may be studied statistically through network analysis or interpreted qualitatively through virtual ethnography. Moreover, organizational change is catalysed through new media, thereby influencing social change at-large, perhaps forming the framework for a transformation from an industrial to an informational society. One notable text is Manuel Castells' The Internet Galaxy—the title of which forms an inter-textual reference to Marshall McLuhan's The Gutenberg Galaxy. Closely related to the sociology of the Internet is digital sociology, which expands the scope of study to address not only the internet but also the impact of the other digital media and devices that have emerged since the first decade of the twenty-first century. Media As with cultural studies, media study is a distinct discipline that owes to the convergence of sociology and other social sciences and humanities, in particular, literary criticism and critical theory. Though neither the production process nor the critique of aesthetic forms is in the remit of sociologists, analyses of socializing factors, such as ideological effects and audience reception, stem from sociological theory and method. Thus the 'sociology of the media' is not a subdiscipline per se, but the media is a common and often indispensable topic. Economic sociology The term "economic sociology" was first used by William Stanley Jevons in 1879, later to be coined in the works of Durkheim, Weber, and Simmel between 1890 and 1920. Economic sociology arose as a new approach to the analysis of economic phenomena, emphasizing class relations and modernity as a philosophical concept. The relationship between capitalism and modernity is a salient issue, perhaps best demonstrated in Weber's The Protestant Ethic and the Spirit of Capitalism (1905) and Simmel's The Philosophy of Money (1900). The contemporary period of economic sociology, also known as new economic sociology, was consolidated by the 1985 work of Mark Granovetter titled "Economic Action and Social Structure: The Problem of Embeddedness". This work elaborated the concept of embeddedness, which states that economic relations between individuals or firms take place within existing social relations (and are thus structured by these relations as well as the greater social structures of which those relations are a part). Social network analysis has been the primary methodology for studying this phenomenon. Granovetter's theory of the strength of weak ties and Ronald Burt's concept of structural holes are two of the best known theoretical contributions of this field. Work, employment, and industry The sociology of work, or industrial sociology, examines "the direction and implications of trends in technological change, globalization, labour markets, work organization, managerial practices and employment relations to the extent to which these trends are intimately related to changing patterns of inequality in modern societies and to the changing experiences of individuals and families the ways in which workers challenge, resist and make their own contributions to the patterning of work and shaping of work institutions." Education The sociology of education is the study of how educational institutions determine social structures, experiences, and other outcomes. It is particularly concerned with the schooling systems of modern industrial societies. A classic 1966 study in this field by James Coleman, known as the "Coleman Report", analysed the performance of over 150,000 students and found that student background and socioeconomic status are much more important in determining educational outcomes than are measured differences in school resources (i.e. per pupil spending). The controversy over "school effects" ignited by that study has continued to this day. The study also found that socially disadvantaged black students profited from schooling in racially mixed classrooms, and thus served as a catalyst for desegregation busing in American public schools. Environment Environmental sociology is the study of human interactions with the natural environment, typically emphasizing human dimensions of environmental problems, social impacts of those problems, and efforts to resolve them. As with other sub-fields of sociology, scholarship in environmental sociology may be at one or multiple levels of analysis, from global (e.g. world-systems) to local, societal to individual. Attention is paid also to the processes by which environmental problems become defined and known to humans. As argued by notable environmental sociologist John Bellamy Foster, the predecessor to modern environmental sociology is Marx's analysis of the metabolic rift, which influenced contemporary thought on sustainability. Environmental sociology is often interdisciplinary and overlaps with the sociology of risk, rural sociology and the sociology of disaster. Human ecology Human ecology deals with interdisciplinary study of the relationship between humans and their natural, social, and built environments. In addition to Environmental sociology, this field overlaps with architectural sociology, urban sociology, and to some extent visual sociology. In turn, visual sociology—which is concerned with all visual dimensions of social life—overlaps with media studies in that it uses photography, film and other technologies of media. Social pre-wiring Social pre-wiring deals with the study of fetal social behavior and social interactions in a multi-fetal environment. Specifically, social pre-wiring refers to the ontogeny of social interaction. Also informally referred to as, "wired to be social". The theory questions whether there is a propensity to socially oriented action already present before birth. Research in the theory concludes that newborns are born into the world with a unique genetic wiring to be social. Circumstantial evidence supporting the social pre-wiring hypothesis can be revealed when examining newborns' behavior. Newborns, not even hours after birth, have been found to display a preparedness for social interaction. This preparedness is expressed in ways such as their imitation of facial gestures. This observed behavior cannot be attributed to any current form of socialization or social construction. Rather, newborns most likely inherit to some extent social behavior and identity through genetics. Principal evidence of this theory is uncovered by examining Twin pregnancies. The main argument is, if there are social behaviors that are inherited and developed before birth, then one should expect twin foetuses to engage in some form of social interaction before they are born. Thus, ten foetuses were analyzed over a period of time using ultrasound techniques. Using kinematic analysis, the results of the experiment were that the twin foetuses would interact with each other for longer periods and more often as the pregnancies went on. Researchers were able to conclude that the performance of movements between the co-twins were not accidental but specifically aimed. The social pre-wiring hypothesis was proved correct: The central advance of this study is the demonstration that 'social actions' are already performed in the second trimester of gestation. Starting from the 14th week of gestation twin foetuses plan and execute movements specifically aimed at the co-twin. These findings force us to predate the emergence of social behavior: when the context enables it, as in the case of twin foetuses, other-directed actions are not only possible but predominant over self-directed actions. Family, gender, and sexuality Family, gender and sexuality form a broad area of inquiry studied in many sub-fields of sociology. A family is a group of people who are related by kinship ties :- Relations of blood / marriage / civil partnership or adoption. The family unit is one of the most important social institutions found in some form in nearly all known societies. It is the basic unit of social organization and plays a key role in socializing children into the culture of their society. The sociology of the family examines the family, as an institution and unit of socialization, with special concern for the comparatively modern historical emergence of the nuclear family and its distinct gender roles. The notion of "childhood" is also significant. As one of the more basic institutions to which one may apply sociological perspectives, the sociology of the family is a common component on introductory academic curricula. Feminist sociology, on the other hand, is a normative sub-field that observes and critiques the cultural categories of gender and sexuality, particularly with respect to power and inequality. The primary concern of feminist theory is the patriarchy and the systematic oppression of women apparent in many societies, both at the level of small-scale interaction and in terms of the broader social structure. Feminist sociology also analyses how gender interlocks with race and class to produce and perpetuate social inequalities. "How to account for the differences in definitions of femininity and masculinity and in sex role across different societies and historical periods" is also a concern. Health, illness, and the body The sociology of health and illness focuses on the social effects of, and public attitudes toward, illnesses, diseases, mental health and disabilities. This sub-field also overlaps with gerontology and the study of the ageing process. Medical sociology, by contrast, focuses on the inner-workings of the medical profession, its organizations, its institutions and how these can shape knowledge and interactions. In Britain, sociology was introduced into the medical curriculum following the Goodenough Report (1944). The sociology of the body and embodiment takes a broad perspective on the idea of "the body" and includes "a wide range of embodied dynamics including human and non-human bodies, morphology, human reproduction, anatomy, body fluids, biotechnology, genetics". This often intersects with health and illness, but also theories of bodies as political, social, cultural, economic and ideological productions. The ISA maintains a Research Committee devoted to "the Body in the Social Sciences". Death, dying, bereavement A subfield of the sociology of health and illness that overlaps with cultural sociology is the study of death, dying and bereavement, sometimes referred to broadly as the sociology of death. This topic is exemplified by the work of Douglas Davies and Michael C. Kearl. Knowledge and science The sociology of knowledge is the study of the relationship between human thought and the social context within which it arises, and of the effects prevailing ideas have on societies. The term first came into widespread use in the 1920s, when a number of German-speaking theorists, most notably Max Scheler, and Karl Mannheim, wrote extensively on it. With the dominance of functionalism through the middle years of the 20th century, the sociology of knowledge tended to remain on the periphery of mainstream sociological thought. It was largely reinvented and applied much more closely to everyday life in the 1960s, particularly by Peter L. Berger and Thomas Luckmann in The Social Construction of Reality (1966) and is still central for methods dealing with qualitative understanding of human society (compare socially constructed reality). The "archaeological" and "genealogical" studies of Michel Foucault are of considerable contemporary influence. The sociology of science involves the study of science as a social activity, especially dealing "with the social conditions and effects of science, and with the social structures and processes of scientific activity." Important theorists in the sociology of science include Robert K. Merton and Bruno Latour. These branches of sociology have contributed to the formation of science and technology studies. Both the ASA and the BSA have sections devoted to the subfield of Science, Knowledge and Technology. The ISA maintains a Research Committee on Science and Technology. Leisure Sociology of leisure is the study of how humans organize their free time. Leisure includes a broad array of activities, such as sport, tourism, and the playing of games. The sociology of leisure is closely tied to the sociology of work, as each explores a different side of the work–leisure relationship. More recent studies in the field move away from the work–leisure relationship and focus on the relation between leisure and culture. This area of sociology began with Thorstein Veblen's Theory of the Leisure Class. Peace, war, and conflict This subfield of sociology studies, broadly, the dynamics of war, conflict resolution, peace movements, war refugees, conflict resolution and military institutions. As a subset of this subfield, military sociology aims towards the systematic study of the military as a social group rather than as an organization. It is a highly specialized sub-field which examines issues related to service personnel as a distinct group with coerced collective action based on shared interests linked to survival in vocation and combat, with purposes and values that are more defined and narrower than within civil society. Military sociology also concerns civilian-military relations and interactions between other groups or governmental agencies. Topics include the dominant assumptions held by those in the military, changes in military members' willingness to fight, military unionization, military professionalism, the increased utilization of women, the military industrial-academic complex, the military's dependence on research, and the institutional and organizational structure of military. Political sociology Historically, political sociology concerned the relations between political organization and society. A typical research question in this area might be: "Why do so few American citizens choose to vote?" In this respect questions of political opinion formation brought about some of the pioneering uses of statistical survey research by Paul Lazarsfeld. A major subfield of political sociology developed in relation to such questions, which draws on comparative history to analyse socio-political trends. The field developed from the work of Max Weber and Moisey Ostrogorsky. Contemporary political sociology includes these areas of research, but it has been opened up to wider questions of power and politics. Today political sociologists are as likely to be concerned with how identities are formed that contribute to structural domination by one group over another; the politics of who knows how and with what authority; and questions of how power is contested in social interactions in such a way as to bring about widespread cultural and social change. Such questions are more likely to be studied qualitatively. The study of social movements and their effects has been especially important in relation to these wider definitions of politics and power. Political sociology has also moved beyond methodological nationalism and analysed the role of non-governmental organizations, the diffusion of the nation-state throughout the Earth as a social construct, and the role of stateless entities in the modern world society. Contemporary political sociologists also study inter-state interactions and human rights. Population and demography Demographers or sociologists of population study the size, composition and change over time of a given population. Demographers study how these characteristics impact, or are impacted by, various social, economic or political systems. The study of population is also closely related to human ecology and environmental sociology, which studies a population's relationship with the surrounding environment and often overlaps with urban or rural sociology. Researchers in this field may study the movement of populations: transportation, migrations, diaspora, etc., which falls into the subfield known as mobilities studies and is closely related to human geography. Demographers may also study spread of disease within a given population or epidemiology. Public sociology Public sociology refers to an approach to the discipline which seeks to transcend the academy in order to engage with wider audiences. It is perhaps best understood as a style of sociology rather than a particular method, theory, or set of political values. This approach is primarily associated with Michael Burawoy who contrasted it with professional sociology, a form of academic sociology that is concerned primarily with addressing other professional sociologists. Public sociology is also part of the broader field of science communication or science journalism. Race and ethnic relations The sociology of race and of ethnic relations is the area of the discipline that studies the social, political, and economic relations between races and ethnicities at all levels of society. This area encompasses the study of racism, residential segregation, and other complex social processes between different racial and ethnic groups. This research frequently interacts with other areas of sociology such as stratification and social psychology, as well as with postcolonial theory. At the level of political policy, ethnic relations are discussed in terms of either assimilationism or multiculturalism. Anti-racism forms another style of policy, particularly popular in the 1960s and 1970s. Religion The sociology of religion concerns the practices, historical backgrounds, developments, universal themes and roles of religion in society. There is particular emphasis on the recurring role of religion in all societies and throughout recorded history. The sociology of religion is distinguished from the philosophy of religion in that sociologists do not set out to assess the validity of religious truth-claims, instead assuming what Peter L. Berger has described as a position of "methodological atheism". It may be said that the modern formal discipline of sociology began with the analysis of religion in Durkheim's 1897 study of suicide rates among Roman Catholic and Protestant populations. Max Weber published four major texts on religion in a context of economic sociology and social stratification: The Protestant Ethic and the Spirit of Capitalism (1905), The Religion of China: Confucianism and Taoism (1915), The Religion of India: The Sociology of Hinduism and Buddhism (1915), and Ancient Judaism (1920). Contemporary debates often centre on topics such as secularization, civil religion, the intersection of religion and economics and the role of religion in a context of globalization and multiculturalism. Social change and development The sociology of change and development attempts to understand how societies develop and how they can be changed. This includes studying many different aspects of society, for example demographic trends, political or technological trends, or changes in culture. Within this field, sociologists often use macrosociological methods or historical-comparative methods. In contemporary studies of social change, there are overlaps with international development or community development. However, most of the founders of sociology had theories of social change based on their study of history. For instance, Marx contended that the material circumstances of society ultimately caused the ideal or cultural aspects of society, while Weber argued that it was in fact the cultural mores of Protestantism that ushered in a transformation of material circumstances. In contrast to both, Durkheim argued that societies moved from simple to complex through a process of sociocultural evolution. Sociologists in this field also study processes of globalization and imperialism. Most notably, Immanuel Wallerstein extends Marx's theoretical frame to include large spans of time and the entire globe in what is known as world systems theory. Development sociology is also heavily influenced by post-colonialism. In recent years, Raewyn Connell issued a critique of the bias in sociological research towards countries in the Global North. She argues that this bias blinds sociologists to the lived experiences of the Global South, specifically, so-called, "Northern Theory" lacks an adequate theory of imperialism and colonialism. There are many organizations studying social change, including the Fernand Braudel Center for the Study of Economies, Historical Systems, and Civilizations, and the Global Social Change Research Project. Social networks A social network is a social structure composed of individuals (or organizations) called "nodes", which are tied (connected) by one or more specific types of interdependency, such as friendship, kinship, financial exchange, dislike, sexual relationships, or relationships of beliefs, knowledge or prestige. Social networks operate on many levels, from families up to the level of nations, and play a critical role in determining the way problems are solved, organizations are run, and the degree to which individuals succeed in achieving their goals. An underlying theoretical assumption of social network analysis is that groups are not necessarily the building blocks of society: the approach is open to studying less-bounded social systems, from non-local communities to networks of exchange. Drawing theoretically from relational sociology, social network analysis avoids treating individuals (persons, organizations, states) as discrete units of analysis, it focuses instead on how the structure of ties affects and constitutes individuals and their relationships. In contrast to analyses that assume that socialization into norms determines behaviour, network analysis looks to see the extent to which the structure and composition of ties affect norms. On the other hand, recent research by Omar Lizardo also demonstrates that network ties are shaped and created by previously existing cultural tastes. Social network theory is usually defined in formal mathematics and may include integration of geographical data into sociomapping. Social psychology Sociological social psychology focuses on micro-scale social actions. This area may be described as adhering to "sociological miniaturism", examining whole societies through the study of individual thoughts and emotions as well as behaviour of small groups. One special concern to psychological sociologists is how to explain a variety of demographic, social, and cultural facts in terms of human social interaction. Some of the major topics in this field are social inequality, group dynamics, prejudice, aggression, social perception, group behaviour, social change, non-verbal behaviour, socialization, conformity, leadership, and social identity. Social psychology may be taught with psychological emphasis. In sociology, researchers in this field are the most prominent users of the experimental method (however, unlike their psychological counterparts, they also frequently employ other methodologies). Social psychology looks at social influences, as well as social perception and social interaction. Stratification, poverty and inequality Social stratification is the hierarchical arrangement of individuals into social classes, castes, and divisions within a society. Modern Western societies stratification traditionally relates to cultural and economic classes arranged in three main layers: upper class, middle class, and lower class, but each class may be further subdivided into smaller classes (e.g. occupational). Social stratification is interpreted in radically different ways within sociology. Proponents of structural functionalism suggest that, since the stratification of classes and castes is evident in all societies, hierarchy must be beneficial in stabilizing their existence. Conflict theorists, by contrast, critique the inaccessibility of resources and lack of social mobility in stratified societies. Karl Marx distinguished social classes by their connection to the means of production in the capitalist system: the bourgeoisie own the means, but this effectively includes the proletariat itself as the workers can only sell their own labour power (forming the material base of the cultural superstructure). Max Weber critiqued Marxist economic determinism, arguing that social stratification is not based purely on economic inequalities, but on other status and power differentials (e.g. patriarchy). According to Weber, stratification may occur among at least three complex variables: Property (class): A person's economic position in a society, based on birth and individual achievement. Weber differs from Marx in that he does not see this as the supreme factor in stratification. Weber noted how managers of corporations or industries control firms they do not own; Marx would have placed such a person in the proletariat. Prestige (status): A person's prestige, or popularity in a society. This could be determined by the kind of job this person does or wealth. Power (political party): A person's ability to get their way despite the resistance of others. For example, individuals in state jobs, such as an employee of the Federal Bureau of Investigation, or a member of the United States Congress, may hold little property or status but they still hold immense power. Pierre Bourdieu provides a modern example in the concepts of cultural and symbolic capital. Theorists such as Ralf Dahrendorf have noted the tendency towards an enlarged middle-class in modern Western societies, particularly in relation to the necessity of an educated work force in technological or service-based economies. Perspectives concerning globalization, such as dependency theory, suggest this effect owes to the shift of workers to the developing countries. Urban and rural sociology Urban sociology involves the analysis of social life and human interaction in metropolitan areas. It is a discipline seeking to provide advice for planning and policy making. After the Industrial Revolution, works such as Georg Simmel's The Metropolis and Mental Life (1903) focused on urbanization and the effect it had on alienation and anonymity. In the 1920s and 1930s The Chicago School produced a major body of theory on the nature of the city, important to both urban sociology and criminology, utilizing symbolic interactionism as a method of field research. Contemporary research is commonly placed in a context of globalization, for instance, in Saskia Sassen's study of the "global city". Rural sociology, by contrast, is the analysis of non-metropolitan areas. As agriculture and wilderness tend to be a more prominent social fact in rural regions, rural sociologists often overlap with environmental sociologists. Community sociology Often grouped with urban and rural sociology is that of community sociology or the sociology of community. Taking various communities—including online communities—as the unit of analysis, community sociologists study the origin and effects of different associations of people. For instance, German sociologist Ferdinand Tönnies distinguished between two types of human association: gemeinschaft (usually translated as "community") and gesellschaft ("society" or "association"). In his 1887 work, Gemeinschaft und Gesellschaft, Tönnies argued that Gemeinschaft is perceived to be a tighter and more cohesive social entity, due to the presence of a "unity of will". The 'development' or 'health' of a community is also a central concern of community sociologists also engage in development sociology, exemplified by the literature surrounding the concept of social capital. Other academic disciplines Sociology overlaps with a variety of disciplines that study society, in particular social anthropology, political science, economics, social work and social philosophy. Many comparatively new fields such as communication studies, cultural studies, demography and literary theory, draw upon methods that originated in sociology. The terms "social science" and "social research" have both gained a degree of autonomy since their origination in classical sociology. The distinct field of social anthropology or anthroposociology is the dominant constituent of anthropology throughout the United Kingdom and Commonwealth and much of Europe (France in particular), where it is distinguished from cultural anthropology. In the United States, social anthropology is commonly subsumed within cultural anthropology (or under the relatively new designation of sociocultural anthropology). Sociology and applied sociology are connected to the professional and academic discipline of social work. Both disciplines study social interactions, community and the effect of various systems (i.e. family, school, community, laws, political sphere) on the individual. However, social work is generally more focused on practical strategies to alleviate social dysfunctions; sociology in general provides a thorough examination of the root causes of these problems. For example, a sociologist might study why a community is plagued with poverty. The applied sociologist would be more focused on practical strategies on what needs to be done to alleviate this burden. The social worker would be focused on action; implementing theses strategies "directly" or "indirectly" by means of mental health therapy, counselling, advocacy, community organization or community mobilization. Social anthropology is the branch of anthropology that studies how contemporary living human beings behave in social groups. Practitioners of social anthropology, like sociologists, investigate various facets of social organization. Traditionally, social anthropologists analyzed non-industrial and non-Western societies, whereas sociologists focused on industrialized societies in the Western world. In recent years, however, social anthropology has expanded its focus to modern Western societies, meaning that the two disciplines increasingly converge. Sociocultural anthropology, which includes linguistic anthropology, is concerned with the problem of difference and similarity within and between human populations. The discipline arose concomitantly with the expansion of European colonial empires, and its practices and theories have been questioned and reformulated along with processes of decolonization. Such issues have re-emerged as transnational processes have challenged the centrality of the nation-state to theorizations about culture and power. New challenges have emerged as public debates about multiculturalism, and the increasing use of the culture concept outside of the academy and among peoples studied by anthropology. These times are not "business-as-usual" in the academy, in anthropology, or in the world, if ever there were such times. Irving Louis Horowitz, in his The Decomposition of Sociology (1994), has argued that the discipline, while arriving from a "distinguished lineage and tradition", is in decline due to deeply ideological theory and a lack of relevance to policy making: "The decomposition of sociology began when this great tradition became subject to ideological thinking, and an inferior tradition surfaced in the wake of totalitarian triumphs." Furthermore: "A problem yet unmentioned is that sociology's malaise has left all the social sciences vulnerable to pure positivism—to an empiricism lacking any theoretical basis. Talented individuals who might, in an earlier time, have gone into sociology are seeking intellectual stimulation in business, law, the natural sciences, and even creative writing; this drains sociology of much needed potential." Horowitz cites the lack of a 'core discipline' as exacerbating the problem. Randall Collins, the Dorothy Swaine Thomas Professor in Sociology at the University of Pennsylvania and a member of the Advisory Editors Council of the Social Evolution & History journal, has voiced similar sentiments: "we have lost all coherence as a discipline, we are breaking up into a conglomerate of specialities, each going on its own way and with none too high regard for each other." In 2007, The Times Higher Education Guide published a list of 'The most cited authors of books in the Humanities' (including philosophy and psychology). Seven of the top ten are listed as sociologists: Michel Foucault (1), Pierre Bourdieu (2), Anthony Giddens (5), Erving Goffman (6), Jürgen Habermas (7), Max Weber (8), and Bruno Latour (10). Journals The most highly ranked general journals which publish original research in the field of sociology are the American Journal of Sociology and the American Sociological Review. The Annual Review of Sociology, which publishes original review essays, is also highly ranked. Many other generalist and specialized journals exist.

Anabolism

Anabolism is the set of metabolic pathways that construct macromolecules like DNA or RNA from smaller units. These reactions require energy, known also as an endergonic process. Anabolism is the building-up aspect of metabolism, whereas catabolism is the breaking-down aspect. Anabolism is usually synonymous with biosynthesis. Pathway Polymerization, an anabolic pathway used to build macromolecules such as nucleic acids, proteins, and polysaccharides, uses condensation reactions to join monomers. Macromolecules are created from smaller molecules using enzymes and cofactors. Energy source Anabolism is powered by catabolism, where large molecules are broken down into smaller parts and then used up in cellular respiration. Many anabolic processes are powered by the cleavage of adenosine triphosphate (ATP). Anabolism usually involves reduction and decreases entropy, making it unfavorable without energy input. The starting materials, called the precursor molecules, are joined using the chemical energy made available from hydrolyzing ATP, reducing the cofactors NAD+, NADP+, and FAD, or performing other favorable side reactions. Occasionally it can also be driven by entropy without energy input, in cases like the formation of the phospholipid bilayer of a cell, where hydrophobic interactions aggregate the molecules. Cofactors The reducing agents NADH, NADPH, and FADH2, as well as metal ions, act as cofactors at various steps in anabolic pathways. NADH, NADPH, and FADH2 act as electron carriers, while charged metal ions within enzymes stabilize charged functional groups on substrates. Substrates Substrates for anabolism are mostly intermediates taken from catabolic pathways during periods of high energy charge in the cell. Functions Anabolic processes build organs and tissues. These processes produce growth and differentiation of cells and increase in body size, a process that involves synthesis of complex molecules. Examples of anabolic processes include the growth and mineralization of bone and increases in muscle mass. Anabolic hormones Endocrinologists have traditionally classified hormones as anabolic or catabolic, depending on which part of metabolism they stimulate. The classic anabolic hormones are the anabolic steroids, which stimulate protein synthesis and muscle growth, and insulin. Photosynthetic carbohydrate synthesis Photosynthetic carbohydrate synthesis in plants and certain bacteria is an anabolic process that produces glucose, cellulose, starch, lipids, and proteins from CO2. It uses the energy produced from the light-driven reactions of photosynthesis, and creates the precursors to these large molecules via carbon assimilation in the photosynthetic carbon reduction cycle, a.k.a. the Calvin cycle. Amino acid biosynthesis All amino acids are formed from intermediates in the catabolic processes of glycolysis, the citric acid cycle, or the pentose phosphate pathway. From glycolysis, glucose 6-phosphate is a precursor for histidine; 3-phosphoglycerate is a precursor for glycine and cysteine; phosphoenol pyruvate, combined with the 3-phosphoglycerate-derivative erythrose 4-phosphate, forms tryptophan, phenylalanine, and tyrosine; and pyruvate is a precursor for alanine, valine, leucine, and isoleucine. From the citric acid cycle, α-ketoglutarate is converted into glutamate and subsequently glutamine, proline, and arginine; and oxaloacetate is converted into aspartate and subsequently asparagine, methionine, threonine, and lysine. Glycogen storage During periods of high blood sugar, glucose 6-phosphate from glycolysis is diverted to the glycogen-storing pathway. It is changed to glucose-1-phosphate by phosphoglucomutase and then to UDP-glucose by UTP--glucose-1-phosphate uridylyltransferase. Glycogen synthase adds this UDP-glucose to a glycogen chain. Gluconeogenesis Glucagon is traditionally a catabolic hormone, but also stimulates the anabolic process of gluconeogenesis by the liver, and to a lesser extent the kidney cortex and intestines, during starvation to prevent low blood sugar. It is the process of converting pyruvate into glucose. Pyruvate can come from the breakdown of glucose, lactate, amino acids, or glycerol. The gluconeogenesis pathway has many reversible enzymatic processes in common with glycolysis, but it is not the process of glycolysis in reverse. It uses different irreversible enzymes to ensure the overall pathway runs in one direction only. Regulation Anabolism operates with separate enzymes from catalysis, which undergo irreversible steps at some point in their pathways. This allows the cell to regulate the rate of production and prevent an infinite loop, also known as a futile cycle, from forming with catabolism. The balance between anabolism and catabolism is sensitive to ADP and ATP, otherwise known as the energy charge of the cell. High amounts of ATP cause cells to favor the anabolic pathway and slow catabolic activity, while excess ADP slows anabolism and favors catabolism. These pathways are also regulated by circadian rhythms, with processes such as glycolysis fluctuating to match an animal's normal periods of activity throughout the day. Etymology The word anabolism is from Neo-Latin, with roots from , "upward" and , "to throw". References Metabolism

Education sciences

Education sciences, also known as education studies, education theory, and traditionally called pedagogy, seek to describe, understand, and prescribe education including education policy. Subfields include comparative education, educational research, instructional theory, curriculum theory and psychology, philosophy, sociology, economics, and history of education. Related are learning theory or cognitive science. History The earliest known attempts to understand education in Europe were by classical Greek philosophers and sophists, but there is also evidence of contemporary (or even preceding) discussions among Arabic, Indian, and Chinese scholars. Philosophy of education Educational thought is not necessarily concerned with the construction of theories as much as the "reflective examination of educational issues and problems from the perspective of diverse disciplines." For example, a cultural theory of education considers how education occurs through the totality of culture, including prisons, households, and religious institutions as well as schools. Other examples are the behaviorist theory of education that comes from educational psychology and the functionalist theory of education that comes from sociology of education. Normative theories of education Normative theories of education provide the norms, goals, and standards of education. In contrast, descriptive theories of education provide descriptions, explanations or predictions of the processes of education. "Normative philosophies or theories of education may make use of the results of [philosophical thought] and of factual inquiries about human beings and the psychology of learning, but in any case they propound views about what education should be, what dispositions it should cultivate, why it ought to cultivate them, how and in whom it should do so, and what forms it should take. In a full-fledged philosophical normative theory of education, besides analysis of the sorts described, there will normally be propositions of the following kinds: 1. Basic normative premises about what is good or right; 2. Basic factual premises about humanity and the world; 3. Conclusions, based on these two kinds of premises, about the dispositions education should foster; 4. Further factual premises about such things as the psychology of learning and methods of teaching; and 5. Further conclusions about such things as the methods that education should use." Examples of the purpose of schools include: to develop reasoning about perennial questions, to master the methods of scientific inquiry, to cultivate the intellect, to create change agents, to develop spirituality, and to model a democratic society. Common educational philosophies include: educational perennialism, educational progressivism, educational essentialism, critical pedagogy, Montessori education, Waldorf education, and democratic education. Normative Curriculum theory Normative theories of curriculum aim to "describe, or set norms, for conditions surrounding many of the concepts and constructs" that define curriculum. These normative propositions differ from those above in that normative curriculum theory is not necessarily untestable. A central question asked by normative curriculum theory is: given a particular educational philosophy, what is worth knowing and why? Some examples are: a deep understanding of the Great Books, direct experiences driven by student interest, a superficial understanding of a wide range knowledge (e.g. Core knowledge), social and community problems and issues, knowledge and understanding specific to cultures and their achievements (e.g. African-Centered Education). Normative Feminist educational theory Scholars such as Robyn Wiegman argue that, "academic feminism is perhaps the most successful institutionalizing project of its generation, with more full-time faculty positions and new doctoral degree programs emerging each year in the field it inaugurated, Women's Studies". Feminist educational theory stems from four key tenets, supported by empirical data based on surveys of feminist educators. The first tenet of feminist educational theory is, "Creation of participatory classroom communities". Participatory classroom communities often are smaller classes built around discussion and student involvement. The second tenet is, "Validation of personal experience". Classrooms in which validation of personal experience occur often are focused around students providing their own insights and experiences in group discussion, rather than relying exclusively on the insight of the educator. The third tenet is, "Encouragement of social understanding and activism". This tenet is generally actualized by classrooms discussing and reading about social and societal aspects that students may not be aware of, along with breeding student self-efficacy. The fourth and final tenet of feminist education is, "Development of critical thinking skills/open-mindedness". Classrooms actively engaging in this tenet encourage students to think for themselves and prompt them to move beyond their comfort zones, working outside the bounds of the traditional lecture-based classroom. Though these tenets at times overlap, they combine to provide the basis for modern feminist educational theory, and are supported by a majority of feminist educators. Feminist educational theory derives from the feminist movement, particularly that of the early 1970s, which prominent feminist bell hooks describes as, "a movement to end sexism, sexist exploitation, and oppression". Academic feminist Robyn Weigman recalls that, "In the early seventies, feminism in the U.S. academy was less an organized entity than a set of practices: an ensemble of courses listed on bulletin boards often taught for free by faculty and community leaders". While feminism traditionally existed outside of the institutionalization of schools (particularly universities), feminist education has gradually taken hold in the last few decades and has gained a foothold in institutionalized educational bodies. "Once fledgling programs have become departments, and faculty have been hired and tenured with full-time commitments". There are supporters of feminist education as well, many of whom are educators or students. Professor Becky Ropers-Huilman recounts one of her positive experiences with feminist education from the student perspective, explaining that she "...felt very 'in charge' of [her] own learning experiences," and "...was not being graded–or degraded... [while completing] the majority of the assigned work for the class (and additional work that [she] thought would add to class discussion)," all while "...[regarding] the teacher's feedback on [her] participation as one perspective, rather than the perspective". Ropers-Huilman experienced a working feminist classroom that successfully motivated students to go above and beyond, succeeding in generating self-efficacy and caring in the classroom. When Ropers-Huilman became a teacher herself, she embraced feminist educational theory, noting that, "[Teachers] have an obligation as the ones who are vested with an assumed power, even if that power is easily and regularly disrupted, to assess and address the effects that it is having in our classrooms". Ropers-Huilman firmly believes that educators have a duty to address feminist concepts such as the use and flow of power within the classroom, and strongly believes in the potential of feminist educational theory to create positive learning experiences for students and teachers as she has personally experienced. Ropers-Huilman also celebrates the feminist classroom's inclusivity, noting that in a feminist classroom, "in which power is used to care about, for, and with others… educational participants can shape practices aimed at creating an inclusive society that discovers and utilizes the potential of its actors". Ropers-Huilman believes that a feminist classroom carries the ability to greatly influence the society as a whole, promoting understanding, caring, and inclusivity. Ropers-Huilman actively engages in feminist education in her classes, focusing on concepts such as active learning and critical thinking while attempting to demonstrate and engage in caring behavior and atypical classroom settings, similar to many other feminist educators. Leading feminist scholar bell hooks argues for the incorporation of feminism into all aspects of society, including education, in her book Feminism is for Everybody. hooks notes that, "Everything [people] know about feminism has come into their lives thirdhand". hooks believes that education offers a counter to the, "...wrongminded notion of feminist movement which implied it was anti-male". hooks cites feminism's negative connotations as major inhibitors to the spread and adoption of feminist ideologies. However, feminist education has seen tremendous growth in adoption in the past few decades, despite the negative connotations of its parent movement. Criticism of Feminist educational theory Opposition to feminist educational theory comes from both those who oppose feminism in general and feminists who oppose feminist educational theory in particular. Critics of feminist educational theory argue against the four basic tenets of the theory, "...[contesting] both their legitimacy and their implementation". Lewis Lehrman particularly describes feminist educational ideology as, "...'therapeutic pedagogy' that substitutes an 'overriding' (and detrimental) value on participatory interaction for the expertise of the faculty" (Hoffman). Lehrman argues that the feminist educational tenets of participatory experience and validation of person experience hinder education by limiting and inhibiting the educator's ability to share his or her knowledge, learned through years of education and experience. Others challenge the legitimacy of feminist educational theory, arguing that it is not unique and is instead a sect of liberatory education. Even feminist educational scholars such as Frances Hoffmann and Jayne Stake are forced to concede that, "feminist pedagogy shared intellectual and political roots with the movements comprising the liberatory education agenda of the past 30 years". These liberatory attempts at the democratization of classrooms demonstrate a growth in liberatory education philosophy that some argue feminist educational theory simply piggybacks off of. The harshest critiques of feminist educational theory often come from feminists themselves. Feminist scholar Robyn Wiegman argues against feminist education in her article "Academic Feminism against Itself", arguing that feminist educational ideology has abandoned the intersectionality of feminism in many cases, and has also focused exclusively on present content with a singular perspective. Wiegman refers to feminist scholar James Newman's arguments, centered around the idea that, "When we fail... to challenge both students and ourselves to theorize alterity as an issue of change over time as well as of geographic distance, ethnic difference, and sexual choice, we repress... not only the 'thickness' of historical difference itself, but also... our (self) implication in a narrative of progress whose hero(in)es inhabit only the present". Newman (and Wiegman) believe that this presentist ideology imbued within modern academic feminism creates an environment breeding antifeminist ideologies, most importantly an abandonment of the study of difference, integral to feminist ideology. Wiegman believes that feminist educational theory does a great disservice to the feminist movement, while failing to instill the critical thinking and social awareness that feminist educational theory is intended to. Educational anthropology Philosophical anthropology is the philosophical study of human nature. In terms of learning, examples of descriptive theories of the learner are: a mind, soul, and spirit capable of emulating the Absolute Mind (Idealism); an orderly, sensing, and rational being capable of understanding the world of things (Realism), a rational being with a soul modeled after God and who comes to know God through reason and revelation (Neo-Thomism), an evolving and active being capable of interacting with the environment (Pragmatism), a fundamentally free and individual being who is capable of being authentic through the making of and taking responsibility for choices (Existentialism). Philosophical concepts for the process of education include Bildung and paideia. Educational anthropology is a sub-field of anthropology and is widely associated with the pioneering work of George Spindler. As the name would suggest, the focus of educational anthropology is obviously on education, although an anthropological approach to education tends to focus on the cultural aspects of education, including informal as well as formal education. As education involves understandings of who we are, it is not surprising that the single most recognized dictum of educational anthropology is that the field is centrally concerned with cultural transmission. Cultural transmission involves the transfer of a sense of identity between generations, sometimes known as enculturation and also transfer of identity between cultures, sometimes known as acculturation. Accordingly, thus it is also not surprising that educational anthropology has become increasingly focused on ethnic identity and ethnic change. Descriptive Curriculum theory Descriptive theories of curriculum explain how curricula "benefit or harm all publics it touches". The term hidden curriculum describes that which is learned simply by being in a learning environment. For example, a student in a teacher-led classroom is learning submission. The hidden curriculum is not necessarily intentional. Instructional theory Instructional theories focus on the methods of instruction for teaching curricula. Theories include the methods of: autonomous learning, coyote teaching, inquiry-based instruction, lecture, maturationism, socratic method, outcome-based education, taking children seriously, transformative learning Educational psychology Educational psychology is an empirical science that provides descriptive theories of how people learn. Examples of theories of education in psychology are: constructivism, behaviorism, cognitivism, and motivational theory Cognitive science Educational neuroscience Educational neuroscience is an emerging field that brings together researchers in diverse disciplines to explore the interactions between biological processes and education. Sociology of education The sociology of education is the study of how public institutions and individual experiences affect education and its outcomes. It is most concerned with the public schooling systems of modern industrial societies, including the expansion of higher, further, adult, and continuing education. Examples of theories of education from sociology include: functionalism, conflict theory, social efficiency, and social mobility.

Hazard

A hazard is a potential source of harm. Substances, events, or circumstances can constitute hazards when their nature would potentially allow them to cause damage to health, life, property, or any other interest of value. The probability of that harm being realized in a specific incident, combined with the magnitude of potential harm, make up its risk. This term is often used synonymously in colloquial speech. Hazards can be classified in several ways which are not mutually exclusive. They can be classified by causing actor (for example, natural or anthropogenic), by physical nature (e.g. biological or chemical) or by type of damage (e.g., health hazard or environmental hazard). Examples of natural disasters with highly harmful impacts on a society are floods, droughts, earthquakes, tropical cyclones, lightning strikes, volcanic activity and wildfires. Technological and anthropogenic hazards include, for example, structural collapses, transport accidents, accidental or intentional explosions, and release of toxic materials. The term climate hazard is used in the context of climate change. These are hazards that stem from climate-related events and can be associated with global warming, such as wildfires, floods, droughts, sea level rise. Climate hazards can combine with other hazards and result in compound event losses (see also loss and damage). For example, the climate hazard of heat can combine with the hazard of poor air quality. Or the climate hazard flooding can combine with poor water quality. In physics terms, common theme across many forms of hazards is the presence of energy that can cause damage, as it can happen with chemical energy, mechanical energy or thermal energy. This damage can affect different valuable interests, and the severity of the associated risk varies. Definition A hazard is defined as "the potential occurrence of a natural or human-induced physical event or trend that may cause loss of life, injury, or other health impacts, as well as damage and loss to property, infrastructure, livelihoods, service provision, ecosystems and environmental resources." A hazard only exists if there is a pathway to exposure. As an example, the center of the Earth consists of molten material at very high temperatures which would be a severe hazard if contact was made with the core. However, there is no feasible way of making contact with the core, therefore the center of the Earth currently poses no hazard. The frequency and severity of hazards are important aspects for risk management. Hazards may also be assessed in relation to the impact that they have. In defining hazard Keith Smith argues that what may be defined as the hazard is only a hazard if there is the presence of humans to make it a hazard. In this regard, human sensitivity to environmental hazards is a combination of both physical exposure (natural and/or technological events at a location related to their statistical variability) and human vulnerability (about social and economic tolerance of the same location). Relationship with other terms Disaster An example of the distinction between a natural hazard and a disaster is that an earthquake is the hazard which caused the 1906 San Francisco earthquake disaster. A natural disaster is the highly harmful impact on a society or community following a natural hazard event. The term "disaster" itself is defined as follows: "Disasters are serious disruptions to the functioning of a community that exceed its capacity to cope using its own resources. Disasters can be caused by natural, man-made and technological hazards, as well as various factors that influence the exposure and vulnerability of a community." The US Federal Emergency Management Agency (FEMA) explains the relationship between natural disasters and natural hazards as follows: "Natural hazards and natural disasters are related but are not the same. A natural hazard is the threat of an event that will likely have a negative impact. A natural disaster is the negative impact following an actual occurrence of natural hazard in the event that it significantly harms a community. Disaster can take various forms, including hurricane, volcano, tsunami, earthquake, drought, famine, plague, disease, rail crash, car crash, tornado, deforestation, flooding, toxic release, and spills (oil, chemicals). A disaster hazard is an extreme geophysical event that is capable of causing a disaster. 'Extreme' in this case means a substantial variation in either the positive or the negative direction from the normal trend; flood disasters can result from exceptionally high precipitation and river discharge, and drought is caused by exceptionally low values. The fundamental determinants of hazard and the risk of such hazards occurring is timing, location, magnitude and frequency. For example, magnitudes of earthquakes are measured on the Richter scale from 1 to 10, whereby each increment of 1 indicates a tenfold increase in severity. The magnitude-frequency rule states that over a significant period of time many small events and a few large ones will occur. Hurricanes and typhoons on the other hand occur between 5 degrees and 25 degrees north and south of the equator, tending to be seasonal phenomena that are thus largely recurrent in time and predictable in location due to the specific climate variables necessary for their formation. Risk and vulnerability The terms hazard and risk are often used interchangeably. However, in terms of risk assessment, these are two very distinct terms. A hazard is an agent that can cause harm or damage to humans, property, or the environment. Risk is the probability that exposure to a hazard will lead to a negative consequence, or more simply, a hazard poses no risk if there is no exposure to that hazard. Risk is a combination of hazard, exposure and vulnerability. For example in terms of water security: examples of hazards are droughts, floods and decline in water quality. Bad infrastructure and bad governance lead to high exposure to risk. Risk can be defined as the likelihood or probability of a given hazard of a given level causing a particular level of loss of damage. The elements of risk are populations, communities, the built environment, the natural environment, economic activities and services which are under threat of disaster in a given area. Another definition of risk is "the probable frequency and probable magnitude of future losses". This definition also focuses on the probability of future loss whereby the degree of vulnerability to hazard represents the level of risk on a particular population or environment. The threats posed by a hazard are: Hazards to people – death, injury, disease and stress Hazards to goods – property damage and economic loss Hazards to environment –loss of flora and fauna, pollution and loss of amenity Classifications Hazards can be classified in several ways. These categories are not mutually exclusive which means that one hazard can fall into several categories. For example, water pollution with toxic chemicals is an anthropogenic hazard as well as an environmental hazard. One of the classification methods is by specifying the origin of the hazard. One key concept in identifying a hazard is the presence of stored energy that, when released, can cause damage. The stored energy can occur in many forms: chemical, mechanical, thermal, radioactive, electrical, etc. The United Nations Office for Disaster Risk Reduction (UNDRR) explains that "each hazard is characterized by its location, intensity or magnitude, frequency and probability". A distinction can also be made between rapid-onset natural hazards, technological hazards, and social hazards, which are described as being of sudden occurrence and relatively short duration, and the consequences of longer-term environmental degradation such as desertification and drought. Hazards may be grouped according to their characteristics. These factors are related to geophysical events, which are not process specific: Areal extent of damage zone Intensity of impact at a point Duration of impact at a point Rate of onset of the event Predictability of the event By causing actor Natural hazard Damage to valuable human interests can occur due to phenomena and processes of the natural environment. Natural disasters such as earthquakes, floods, volcanoes and tsunami have threatened people, society, the natural environment, and the built environment, particularly more vulnerable people, throughout history, and in some cases, on a day-to-day basis. According to the Red Cross, each year 130,000 people are killed, 90,000 are injured and 140 million are affected by unique events known as natural disasters. Potentially dangerous phenomena which are natural or predominantly natural (for example, exceptions are intentional floods) can be classified in these categories: Meteorological and hydrological hazards, e.g. lightning, storm, flood, sandstorm, fog, rogue wave, tsunami, snow, cold wave, heat wave Geological hazards Earthquake Volcanism, which can cause a wide range of events, such as lava flow and ash fall Surface or near-surface events, especially erosion and mass wasting (e.g. landslide) Extraterrestrial hazards, e.g. solar storm, impact event Natural hazards can be influenced by human actions in different ways and to varying degrees, e.g. land-use change, drainage and construction. Humans play a central role in the existence of natural hazards because "it is only when people and their possessions get in the way of natural processes that hazard exists". A natural hazard can be considered as a geophysical event when it occurs in extremes and a human factor is involved that may present a risk. There may be an acceptable variation of magnitude which can vary from the estimated normal or average range with upper and lower limits or thresholds. In these extremes, the natural occurrence may become an event that presents a risk to the environment or people. For example, above-average wind speeds resulting in a tropical depression or hurricane according to intensity measures on the Saffir–Simpson scale will provide an extreme natural event that may be considered a hazard. Seismic hazard Tsunamis can be caused by geophysical hazards, such as in the 2004 Indian Ocean earthquake and tsunami. Although generally a natural phenomenon, earthquakes can sometimes be induced by human interventions, such as injection wells, large underground nuclear explosions, excavation of mines, or reservoirs. Volcanic hazard Anthropogenic hazard Anthropogenic hazards, or human-induced hazards, are "induced entirely or predominantly by human activities and choices". These can be societal, technological or environmental hazards. Technological hazard Technological hazards are created by the possibility of failure associated with human technology (including emerging technologies), which can also impact the economy, health and national security. For example, technological hazards can arise from the following events: Transport accidents: traffic collisions, navigation accidents, rail accidents, aviation accidents Nuclear materials-related accidents: nuclear plant accidents, nuclear weapon accidents and other nuclear accidents Chemical accidents and accidental explosions Mining accidents Space accidents Technological failures (including those that affect information and communications technology, such as cybersecurity threats) can cause disruptions to the energy industry (e.g. power outages), telecommunications (e.g. Internet outage), healthcare, banking, transportation, food supply, water supply and other important services. Structural failures or construction accidents A mechanical hazard is any hazard involving a machine or industrial process. Motor vehicles, aircraft, and air bags pose mechanical hazards. Compressed gases or liquids can also be considered a mechanical hazard. Hazard identification of new machines and/or industrial processes occurs at various stages in the design of the new machine or process. These hazard identification studies focus mainly on deviations from the intended use or design and the harm that may occur as a result of these deviations. These studies are regulated by various agencies such as the Occupational Safety and Health Administration and the National Highway Traffic Safety Administration. Engineering hazards occur when human structures fail (e.g. building or structural collapse, bridge failures, dam failures) or the materials used in their construction prove to be hazardous. Societal hazard Societal hazards can arise from civil disorders, explosive remnants of war, violence, crowd accidents, financial crises, etc. However, the United Nations Office for Disaster Risk Reduction (UNDRR) Hazard Definition & Classification Review (Sendai Framework 2015 - 2030) specifically excludes armed conflict from the anthropogenic hazard category, as these hazards are already recognised under international humanitarian law. Waste disposal In managing waste many hazardous materials are put in the domestic and commercial waste stream. In part this is because modern technological living uses certain toxic or poisonous materials in the electronics and chemical industries. Which, when they are in use or transported, are usually safely contained or encapsulated and packaged to avoid any exposure. In the waste stream, the waste products exterior or encapsulation breaks or degrades and there is a release and exposure to hazardous materials into the environment, for people working in the waste disposal industry, those living around sites used for waste disposal or landfill and the general environment surrounding such sites. Socionatural hazard There are different ways to group hazards by origin. The definition by UNDRR states: "Hazards may be natural, anthropogenic or socionatural in origin." The socionatural hazards are those that are "associated with a combination of natural and anthropogenic factors, including environmental degradation and climate change". Climate hazard The term climate hazard or climatic hazard is used in the context of climate change, for example in the IPCC Sixth Assessment Report. These are hazards that stem from climate-related events such as wildfires, floods, droughts, sea level rise. Climate hazards in the context of water include: Increased temperatures, changes in rainfall patterns between the wet and dry season (increased rainfall variability) and sea level rise. The reason why increasing temperatures is listed here as a climate hazard is because "warming temperatures may result in higher evapotranspiration, in turn leading to drier soils". Waterborne diseases are also connected to climate hazards. Climate hazards can combine with other hazards and result in compound event losses (see also loss and damage). For example, the climate hazard of heat can combine with the hazard of poor air quality. Or the climate hazard flooding can combine with poor water quality. Climate scientists have pointed out that climate hazards affect different groups of people differently, depending on their climate change vulnerability: There are "factors that make people and groups vulnerable (e.g., poverty, uneven power structures, disadvantage and discrimination due to, for example, social location and the intersectionality or the overlapping and compounding risks from ethnicity or racial discrimination, gender, age, or disability, etc.)". By physical nature Biological hazard Biological hazards, also known as biohazards, originate in biological processes of living organisms and pose threats to the health of humans, the security of property, or the environment. Biological hazards include pathogenic microorganisms, such as viruses and bacteria, epidemics, pandemics, parasites, pests, animal attacks, venomous animals, biological toxins and foodborne illnesses. For example, naturally occurring bacteria such as Escherichia coli and Salmonella are well known pathogens, and a variety of measures have been taken to limit human exposure to these microorganisms through food safety, good personal hygiene, and education. The potential for new biological hazards also exists through the discovery of new microorganisms and the development of new genetically modified (GM) organisms. The use of new GM organisms is regulated by various governmental agencies. The US Environmental Protection Agency (EPA) controls GM plants that produce or resist pesticides (i.e. Bt corn and Roundup ready crops). The US Food and Drug Administration (FDA) regulates GM plants that will be used as food or for medicinal purposes. Biological hazards can include medical waste or samples of a microorganism, virus or toxin (from a biological source) that can affect health. Many biological hazards are associated with food, including certain viruses, parasites, fungi, bacteria, and plant and seafood toxins. Pathogenic Campylobacter and Salmonella are common foodborne biological hazards. The hazards from these bacteria can be avoided through risk mitigation steps such as proper handling, storing, and cooking of food. Diseases can be enhanced by human factors such as poor sanitation or by processes such as urbanization. Chemical hazard A chemical can be considered a hazard if by its intrinsic properties it can cause harm or danger to humans, property, or the environment. Health hazards associated with chemicals are dependent on the dose or amount of the chemical. For example, iodine in the form of potassium iodate is used to produce iodised salt. When applied at a rate of 20  mg of potassium iodate per 1000 mg of table salt, the chemical is beneficial in preventing goitre, while iodine intakes of 1200–9500  mg in one dose has been known to cause death. Some chemicals have a cumulative biological effect, while others are metabolically eliminated over time. Other chemical hazards may depend on concentration or total quantity for their effects. Some harmful chemicals occur naturally in certain geological formations, such as arsenic. Other chemicals include products with commercial uses, such as agricultural and industrial chemicals, as well as products developed for home use. A variety of chemical hazards have been identified. However, every year companies produce more new chemicals to fill new needs or to take the place of older, less effective chemicals. Laws, such as the Federal Food, Drug, and Cosmetic Act and the Toxic Substances Control Act in the US, require protection of human health and the environment for any new chemical introduced. In the US, the EPA regulates new chemicals that may have environmental impacts (i.e., pesticides or chemicals released during a manufacturing process), while the FDA regulates new chemicals used in foods or as drugs. The potential hazards of these chemicals can be identified by performing a variety of tests before the authorization of usage. The number of tests required and the extent to which the chemicals are tested varies, depending on the desired usage of the chemical. Chemicals designed as new drugs must undergo more rigorous tests than those used as pesticides. Pesticides, which are normally used to control unwanted insects and plants, may cause a variety of negative effects on non-target organisms. DDT can build up, or bioaccumulate, in birds, resulting in thinner-than-normal eggshells, which can break in the nest. The organochlorine pesticide dieldrin has been linked to Parkinson's disease. Corrosive chemicals like sulfuric acid, which is found in car batteries and research laboratories, can cause severe skin burns. Many other chemicals used in industrial and laboratory settings can cause respiratory, digestive, or nervous system problems if they are inhaled, ingested, or absorbed through the skin. The negative effects of other chemicals, such as alcohol and nicotine, have been well documented. Organohalogens are a family of synthetic organic molecules which all contain atoms of one of the halogens. Such materials include PCBs, Dioxins, DDT, Freon and many others. Although considered harmless when first produced, many of these compounds are now known to have profound physiological effects on many organisms including man. Many are also fat soluble and become concentrated through the food chain. Radioactive or electromagnetic hazard Radioactive materials produce ionizing radiation which may be very harmful to living organisms. Damage from even a short exposure to radioactivity may have long-term adverse health consequences. Thermal or fire hazard Fire hazard Threats to fire safety are commonly referred to as fire hazards. A fire hazard may include a situation that increases the likelihood of a fire or may impede escape in the event a fire occurs. Casualties resulting from fires, regardless of their source or initial cause, can be aggravated by inadequate emergency preparedness. Such hazards as a lack of accessible emergency exits, poorly marked escape routes, or improperly maintained fire extinguishers or sprinkler systems may result in many more deaths and injuries than might occur with such protections. Kinetic hazard Kinetic energy is involved in hazards associated with noise, falling, or vibration. By type of damage Health hazard Hazards that would affect the health of exposed persons, usually having an acute or chronic illness as the consequence. Fatality would not normally be an immediate consequence. Health hazards may cause measurable changes in the body which are generally indicated by the development of signs and symptoms in the exposed persons, or non-measurable, subjective symptoms. Ergonomic hazard Ergonomic hazards are physical conditions that may pose a risk of injury to the musculoskeletal system, such as the muscles or ligaments of the lower back, tendons or nerves of the hands/wrists, or bones surrounding the knees. Ergonomic hazards include things such as awkward or extreme postures, whole-body or hand/arm vibration, poorly designed tools, equipment, or workstations, repetitive motion, and poor lighting. Ergonomic hazards occur in both occupational and non-occupational settings such as in workshops, building sites, offices, home, school, or public spaces and facilities. Occupational hazard Psychosocial hazard Psychological or psychosocial hazards are hazards that affect the psychological well-being of people, including their ability to participate in a work environment among other people. Psychosocial hazards are related to the way work is designed, organized, and managed, as well as the economic and social contexts of work, and are associated with psychiatric, psychological, and/or physical injury or illness. Linked to psychosocial risks are issues such as occupational stress and workplace violence, which are recognized internationally as major challenges to occupational health and safety. Environmental hazard Property Cultural property Cultural property can be damaged, lost or destroyed by different events or processes, including war, vandalism, theft, looting, transport accident, water leak, human error, natural disaster, fire, pests, pollution and progressive deterioration. By status Hazards are sometimes classified into three modes or statuses: Dormant—The situation environment is currently affected. For instance, a hillside may be unstable, with the potential for a landslide, but there is nothing below or on the hillside that could be affected. Armed—People, property, or environment are in potential harm's way. Active—A harmful incident involving the hazard has actually occurred. Often this is referred to not as an "active hazard" but as an accident, emergency, incident, or disaster. Analysis and management A range of methodologies are used to assess hazards and to manage them: (HACCP) (HAZOP) Hazard symbol See also References External links

Dimensions of globalization

Manfred Steger, professor of Global Studies at the University of Hawaii at Manoa argues that globalization has four main dimensions: economic, political, cultural, ecological, with ideological aspects of each category. David Held's book Global Transformations is organized around the same dimensions, though the ecological is not listed in the title. This set of categories relates to the four-domain approach of circles of social life, and Circles of Sustainability. Steger compares the current study of globalization to the ancient Buddhist parable of blind scholars and their first encounter with an elephant. Similar to the blind scholars, some globalization scholars are too focused on compacting globalization into a singular process and clashes over “which aspect of social life constitutes its primary domain” prevail. Dimensions Economic Economic globalization is the intensification and stretching of economic interrelations around the globe. It encompasses such things as the emergence of a new global economic order, the internationalization of trade and finance, the changing power of transnational corporations, and the enhanced role of international economic institutions. Political Political globalization is the intensification and expansion of political interrelations around the globe. Aspects of political globalization include the modern-nation state system and its changing place in today's world, the role of global governance, and the direction of our global political systems. Cultural Cultural globalization is the intensification and expansion of cultural flows across the globe. Culture is a very broad concept and has many facets, but in the discussion on globalization, Steger means it to refer to “the symbolic construction, articulation, and dissemination of meaning.” Topics under this heading include discussion about the development of a global culture, or lack thereof, the role of the media in shaping our identities and desires, and the globalization of languages. Ecological Topics of ecological globalization include population growth, access to food, worldwide reduction in biodiversity, the gap between rich and poor as well as between the global North and global South, human-induced climate change, and global environmental degradation. Ideologies According to Steger, there are three main types of globalisms (ideologies that endow the concept of globalization with particular values and meanings): market globalism, justice globalism, and religious globalisms. Steger defines them as follows: Market globalism seeks to endow ‘globalization’ with free-market norms and neoliberal meanings. Justice globalism constructs an alternative vision of globalization based on egalitarian ideals of global solidarity and distributive justice. Religious globalisms struggle against both market globalism and justice globalism as they seek to mobilize a religious values and beliefs that are thought to be under severe attack by the forces of secularism and consumerism. These ideologies of globalization (or globalisms) then relate to broader imaginaries and ontologies. See also Cultural globalization Globalism Globalization References Notes Globalization

Sustainable Development Goal 15

Sustainable Development Goal 15 (SDG 15 or Global Goal 15) is about "Life on land". One of the 17 Sustainable Development Goals established by the United Nations in 2015, the official wording is: "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss". The Goal has 12 targets to be achieved by 2030. Progress towards targets will be measured by 14 indicators. The nine outcome targets include: Conserve and restore terrestrial and freshwater ecosystems; end deforestation and restore degraded forests; end desertification and restore degraded land; ensure conservation of mountain ecosystems, protect biodiversity and natural habitats; protect access to genetic resources and fair sharing of the benefits; eliminate poaching and trafficking of protected species; prevent invasive alien species on land and in water ecosystems; and integrate ecosystem and biodiversity in governmental planning. The three means of implementation targets include: Increase financial resources to conserve and sustainably use ecosystem and biodiversity; finance and incentivize sustainable forest management; combat global poaching and trafficking. An annual report is prepared by the Secretary-General of the United Nations evaluating the progress towards the Sustainable Development Goals. It provides data on changes in forest areas, desertification, biodiversity loss and other parameters that are of relevance for SDG 15. Targets, indicators and progress The UN has defined 12 Targets and 14 Indicators for SDG 15. Five of them are to be achieved by the year 2020, two by the year 2030 and the rest have no target year. Each of the targets also has one or more indicators to measure progress. In total there are fourteen indicators for SDG 15. FAO is the custodian agency for three of the indicators for SDG targets 15.1, 15.2 and 15.4. Target 15.1: Conserve and restore terrestrial and freshwater ecosystems The full title of Target 15.1 is: "By 2020, ensure the conservation, restoration and sustainable use of terrestrial and inland freshwater ecosystems and their services, in particular forests, wetlands, mountains and drylands, in line with obligation under international agreements." This target has two indicators: Indicator 15.1.1: Forest area as a proportion of the total land area Indicator 15.1.2: Proportion of important sites for terrestrial and freshwater biodiversity that are covered by protected areas, by ecosystem type Forests cover roughly 4 billion hectares or 30.7 per cent of the world's land area. 93 percent are natural forests and 7 percent are planted. The forest area is defined by the land under natural or planted groups of trees of at least 5 meters in situ. The trees can be either be productive or non-productive and should not include fruit plantations and agroforestry systems and trees in urban parks and gardens. Protected areas are defined by three indicators: 1) the proportion of total terrestrial area classified as protected 2) the proportion of important sites of terrestrial biodiversity who are protected 3) and proportion of important sites of freshwater biodiversity that are protected. Target 15.2: End deforestation and restore degraded forests The full title of Target 15.2 is: "By 2020, promote the implementation of sustainable management of all types of forests, halt deforestation, restore degraded forests and substantially increase afforestation and reforestation globally." This target has one Indicator: Indicator 15.2.1 is the "Progress towards sustainable forest management". The United Nations General Assembly has defined Sustainable forest management as a dynamic and evolving concept that aims to maintain and enhance the economic, social and environmental values of all types of forests, for the benefit of present and future generations (Resolution A/RES/62/98). It aims to find a balance between the increasing demands for forest products and the benefits as well as preserving the health and diversity of the forests. SDG indicator 15.2.1 is composed of five sub-indicators that measure progress towards all dimensions of sustainable forest management. They provide qualification to the management of forest areas and assess areas with a set on national and international standards. Target 15.3: End desertification and restore degraded land The full title of Target 15.3 is: "By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world." This target has one indicator: Indicator 15.3.1 is the "Proportion of land that is degraded over the total land area". Desertification affects as much as one-sixth of the world's population, 70% of all drylands, and one-quarter of the total land area of the world. It also leads to spreading poverty and the degradation of billion hectares of cropland. Target 15.4: Ensure conservation of mountain ecosystems The full title of Target 15.4 is: "By 2030, ensure the conservation of mountain ecosystems, including their biodiversity, to enhance their capacity to provide benefits that are essential for sustainable development." This target has two indicators: Indicator 15.4.1: Coverage by protected areas of important sites for mountain biodiversity Indicator 15.4.2: Mountain Green Cover Index The Mountain Green Cover Index measured the percentage of mountain environments covered by green areas and the capacity of those areas to fulfil their ecosystem roles. As of 2017, 76% of the world's mountain areas were covered by green vegetation, including forests, shrubs, grassland and cropland. The Mountain Green Cover was lowest in Western Asia and Northern Africa (60%) and highest in Oceania (96%). Target 15.5: Protect biodiversity and natural habitats The full title of Target 15.5 is: "Take urgent and significant action to reduce the degradation of natural habitats, halt the loss of biodiversity and, by 2020, protect and prevent the extinction of threatened species." This target has one indicator: Indicator 15.5.1 is the "Red List Index". A report in 2018 stated that "biodiversity must be mainstreamed across these sectors and spatial planning integrated accordingly." Target 15.6: Protect access to genetic resources and fair sharing of the benefits The full title of Target 15.6 is: "Promote fair and equitable sharing of the benefits arising from the utilization of genetic resources and promote appropriate access to such resources, as internationally agreed." This target has one indicator: Indicator 15.6.1 is the "Number of countries that have adopted legislative, administrative and policy frameworks to ensure fair and equitable sharing of benefits". This indicator is used to track countries' participation in protocols related to the promotion and sharing of genetic resources for plants, food and agriculture. Target 15.7: Eliminate poaching and trafficking of protected species The full title of Target 15.7 is: "Take urgent action to end poaching and trafficking of protected species of flora and fauna and address both demand and supply of illegal wildlife products." This target has one Indicator: Indicator 15.7.1 is the "Proportion of traded wildlife that was poached or illicitly trafficked". In general, wildlife trade policies that incentivize sustainable use typically have more immediate positive effects on wildlife populations than outright trade bans. No data is available for this indicator yet. Target 15.8: Prevent invasive alien species on land and in water ecosystems The full title of Target 15.8 is: "By 2020, introduce measures to prevent the introduction and significantly reduce the impact of invasive alien species on land and water ecosystems and control or eradicate the priority species." This target has one Indicator: Indicator is 15.8.1 is the "Proportion of countries adopting relevant national legislation and adequately resourcing the prevention or control of invasive alien species". Wildlife poaching and trafficking threaten biodiversity and ecosystems as well as local livelihoods, wellbeing and security. Trafficking is normally driven by organized crime, and made easy by corruption and weak governance. Target 15.9: Integrate ecosystem and biodiversity in governmental planning The full title of Target 15.9 is: "By 2020, integrate ecosystem and biodiversity values into national and local planning, development processes, poverty reduction strategies and accounts." Indicator is 15.9.1 is the "Progress towards national targets established in accordance with Aichi Biodiversity Target 2 of the Strategic Plan for Biodiversity 2011–2020". "Aichi Biodiversity Target 2" addresses the underlying causes of biodiversity loss. Target 15.a: Increase financial resources to conserve and sustainably use ecosystem and biodiversity The full title of Target 15.a is: "Mobilize and significantly increase financial resources from all sources to conserve and sustainably use biodiversity and ecosystems." This target has one Indicator: Indicator 15.a.1 is the "Official development assistance and public expenditure on conservation and sustainable use of biodiversity and ecosystems". Target 15.b: Finance and incentivize sustainable forest management The full title of Target 15.b is: "Mobilize significant resources from all sources and at all levels to finance sustainable forest management and provide adequate incentives to developing countries to advance such management, including for conservation and reforestation." This target has one indicator: Indicator 15.b.1 is the "Official development assistance and public expenditure on conservation and sustainable use of biodiversity and ecosystems". This target aims at mobilizing resources at all levels to finance sustainable forest management. The United Nations Strategic Plan for Forests 2017–2030 (UNSPF) presents a global framework for actions at all levels to sustainably manage forests and halt deforestation and forest degradation. Target 15.c: Combat global poaching and trafficking The full title of Target 15.c is: "Enhance global support for efforts to combat poaching and trafficking of protected species, including by increasing the capacity of local communities to pursue sustainable livelihood opportunities." This target has one indicator: Indicator 15.c.1 is the "Proportion of traded wildlife that was poached or illicitly trafficked". The illegal trade and animal trafficking have grown significantly to become one of the world's largest black markets valued at tens of billions of dollars. The challenges to combat global poaching and trafficking need to be addressed by enforcing laws and strengthening institutions. Custodian agencies The custodian agencies are responsible for data gathering and reporting on the indicators. They are: Indicator 15.1.1, 15.2.1 and 15.4.2: Food and Agriculture Organization (FAO) Indicator 15.1.2: United Nations Environmental Programme-World Conservation Monitoring Center (UNEP-WCMC) and United Nations Environmental Programme Indicator 15.3.1 and 15.4.1: United Nations Convention to Combat Desertification (UNCCD) Indicator 15.5.1 and 15.8.1: International Union for Conservation of Nature (IUCN) Indicator 15.6.1: Convention on Biological Diversity (CBD-Secretariat) Indicator 15.7.1 and 15.c.1: United Nations Office on Drugs and Crime, and Convention for International Trade in Endangered Species (CITIES) Indicator 15.9.1: Convention on Biological Diversity (CBD-Secretariat) and United Nations Environmental Programme (UNEP) Indicator 15.a.1, 15.6.1 and 15.b.1: Organization for Economic Cooperation and Development (OECD), United Nations Environmental Programme (UNEP) and World Bank (WB) Monitoring and progress An annual report is prepared by the Secretary-General of the United Nations evaluating the progress towards the Sustainable Development Goals. According to the expert group meeting in preparation for the High-level Political Forum of 2018, SDG 15 needs more indicators in areas such as forest intactness, management effectiveness of protected areas, and meaningful integration of biodiversity into other processes. Challenges , there is approximately a $700 billion gap in financial support to help low-income countries protect biodiversity. Impacts of COVID-19 pandemic In 2020, there was brief progress on SDGs 12 to 15 on sustainable production and consumption, climate action and biodiversity conservation, but these gains were quickly offset once restrictions were lifted. This applies to CO₂ emissions, which declined in major economies during lockdowns, but went quickly back to their pre-pandamic levels after restrictions were lifted. It is estimated that deforestation increased by 12% from 2019 to 2020, and plastic consumption and waste may also increase during pandemic. Links with other SDGs The UN 17 Sustainable Development Goals are inherently interconnected, most of the goals can be achieved only when others are also achieved. And achieving any individual goal tends to help the achievement of the other goals. The impact of SDG 15 on gender equality (SDG 5) is also significant. In many parts of the world, women are farmers, especially poor women living in rural areas. They are the main labor force in growing crops, often depend on forests for fuel, fodder and food. Their limited ownership of the land reduces their ability to adapt to losses or decide how to use it. By protecting biodiversity and thus maintaining agricultural productivity, can also empower gender equality. When forest conditions and regeneration improve, women themselves will get a greater political voice. For SDG 6 and SDG 7, the availability and quality of water from the functioning of ecosystems, especially forest ecological system. Protecting biodiversity, and maintaining the integrity of wetlands and forests play a huge role in the acquisition and replenishment of freshwater resources because natural ecosystems act as filters to clean water and protect it from diseases that can harm the animal or human health. SDG 15 has a direct link to SDG 8 includes high-yield agriculture and tourism, which attracts tourists through protected ecosystems and biodiverse environments, thereby enhancing economic returns. Maintaining biodiversity plays a vital role in helping to mitigate and adapt to climate change. Mangrove forests, for example, account for approximately 1% of carbon sequestration by the world's forests, but about 14% by the global ocean. Therefore, negative impacts on mangrove habitats can result in very high GHG emissions. The impact of land-based activities such as agriculture, land reclamation and urban development on ecosystems demonstrates the high degree of linkage between SDG 13, SDG 14 and SDG 15, and the importance of the overall management of all three.

Technocentrism

Technocentrism is a value system that is centered on technology and its ability to control and protect the environment. Technocentrics argue that technology can address ecological problems through its problem-solving ability, efficiency, and its managerial means. Specifically, these capabilities allow humans control over nature, allowing them to correct or negotiate environmental risks or problems. Although technocentrics may accept that environmental problems exist, they do not see them as problems to be solved by a reduction in industry. Rather, environmental problems are seen as problems to be solved using rational, scientific and technological means. They also believe in scientific research. Indeed, technocentrics see the way forward for both developed and developing countries, and the solutions to environmental problems, as lying in scientific and technological advancement (sometimes referred to as sustainopreneurship). Origin of term The term was claimed to have been coined by Seymour Papert in 1987 as a combination of techno- and egocentrism: I coined the word technocentrism from Piaget's use of the word egocentrism. This does not imply that children are selfish, but simply means that when a child thinks, all questions are referred to the self, to the ego. Technocentrism is the fallacy of referring all questions to the technology. However, references to technocentrism date back well before this (see, for example and). Among the earliest references cited by O'Riordan in his book "Environmentalism" (which includes extensive discussion of ecocentric and technocentric modes of thought) is that of Hays in 1959 where technocentrism is characterised as: The application of rational and 'value-free' scientific and managerial techniques by a professional elite, who regarded the natural environment as 'neutral stuff' from which man could profitably shape his destiny. Technocentrism vs ecocentrism Technocentrism is often contrasted with ecocentrism. Ecocentrics, including deep ecologists, see themselves as being subject to nature, rather than in control of it. They lack faith in modern technology and the bureaucracy attached to it so they maintain responsibility for the environment. Ecocentrics will argue that the natural world should be respected for its processes and products and that low-impact technology and self-sufficiency is more desirable than technological control of nature. Fundamentally, ecocentrism maintains that concerns for the natural environment should dominate the needs of humankind, pitting it against the anthropocentric position of technocentrism, which pushes the needs of humans at the forefront even at the expense of everything else. There are theorists who claim that despite their incompatibilities, technocentrism and ecocentrism can be integrated into one framework because they share several similarities. For instance, it is proposed that technocentrism can facilitate ecocentrism, particularly in the area of policy-making, through shared goals and shared recycled resources. There is also the case of the so-called sustaincentric worldview, which was developed as a product of ecocentric and technocentric views.

Environmental factor

An environmental factor, ecological factor or eco factor is any factor, abiotic or biotic, that influences living organisms. Abiotic factors include ambient temperature, amount of sunlight, air, soil, water and pH of the water soil in which an organism lives. Biotic factors would include the availability of food organisms and the presence of biological specificity, competitors, predators, and parasites. Overall An organism's genotype (e.g., in the zygote) translated into the adult phenotype through development during an organism's ontogeny, and subject to influences by many environmental effects. In this context, a phenotype (or phenotypic trait) can be viewed as any definable and measurable characteristic of an organism, such as its body mass or skin color. Apart from the true monogenic genetic disorders, environmental factors may determine the development of disease in those genetically predisposed to a particular condition. Pollution, stress, physical and mental abuse, diet, exposure to toxins, pathogens, radiation and chemicals found in almost all personal-care products and household cleaners are common environmental factors that determine a large segment of non-hereditary disease. If a disease process is concluded to be the result of a combination of genetic and environmental factor influences, its etiological origin can be referred to as having a multifactorial pattern. Cancer is often related to environmental factors. Maintaining a healthy weight, eating a healthy diet, minimizing alcohol and eliminating smoking reduces the risk of developing the disease, according to researchers. Environmental triggers for asthma and autism have been studied too. Exposome The exposome encompasses the set of human environmental (i.e. non-genetic) exposures from conception onwards, complementing the genome. The exposome was first proposed in 2005 by cancer epidemiologist Christopher Paul Wild in an article entitled "Complementing the genome with an "exposome": the outstanding challenge of environmental exposure measurement in molecular epidemiology". The concept of the exposome and how to assess it has led to lively discussions with varied views in 2010, 2012, 2014 and 2021. In his 2005 article, Wild stated, "At its most complete, the exposome encompasses life-course environmental exposures (including lifestyle factors), from the prenatal period onwards." The concept was first proposed to draw attention to the need for better and more complete environmental exposure data for causal research, in order to balance the investment in genetics. According to Wild, even incomplete versions of the exposome could be useful to epidemiology. In 2012, Wild outlined methods, including personal sensors, biomarkers, and 'omics' technologies, to better define the exposome. He described three overlapping domains within the exposome: a general external environment including the urban environment, education, climate factors, social capital, stress, a specific external environment with specific contaminants, radiation, infections, lifestyle factors (e.g. tobacco, alcohol), diet, physical activity, etc. an internal environment to include internal biological factors such as metabolic factors, hormones, gut microflora, inflammation, oxidative stress. In late 2013, this definition was explained in greater depth in the first book on the exposome. In 2014, the same author revised the definition to include the body's response with its endogenous metabolic processes which alter the processing of chemicals. More recently, evidenced by metabolic exposures in and around the time of pregnancy, the maternal metabolic exposome includes exposures such as maternal obesity/overweight and diabetes, and malnutrition, including high fat/high calorie diets, which are associated with poor fetal, infant and child growth, and increased incidence of obesity and other metabolic disorders in later life. Measurement For complex disorders, specific genetic causes appear to account for only 10-30% of the disease incidence, but there has been no standard or systematic way to measure the influence of environmental exposures. Some studies into the interaction of genetic and environmental factors in the incidence of diabetes have demonstrated that "environment-wide association studies" (EWAS, or exposome-wide association studies) may be feasible. However, it is not clear what data sets are most appropriate to represent the value of "E". Research initiatives As of 2016, it may not be possible to measure or model the full exposome, but several European projects have started to make first attempts. In 2012, the European Commission awarded two large grants to pursue exposome-related research. The HELIX project at the Barcelona-based Centre for Research in Environmental Epidemiology was launched around 2014, and aimed to develop an early-life exposome. A second project, Exposomics, based at Imperial College London, launched in 2012, aimed to use smartphones utilising GPS and environmental sensors to assess exposures. In late 2013, a major initiative called the "Health and Environment-Wide Associations based on Large Scale population Surveys" or HEALS, began. Touted as the largest environmental health-related study in Europe, HEALS proposes to adopt a paradigm defined by interactions between DNA sequence, epigenetic DNA modifications, gene expression, and environmental factors. In December 2011, the US National Academy of Sciences hosted a meeting entitled "Emerging Technologies for Measuring Individual Exposomes." A Centers for Disease Control and Prevention overview, "Exposome and Exposomics", outlines the three priority areas for researching the occupational exposome as identified by the National Institute for Occupational Safety and Health. The National Institutes of Health (NIH) has invested in technologies supporting exposome-related research including biosensors, and supports research on gene–environment interactions. Proposed Human Exposome Project (HEP) The idea of a Human Exposome Project, analogous to the Human Genome Project, has been proposed and discussed in numerous scientific meetings, but as of 2017, no such project exists. Given the lack of clarity on how science would go about pursuing such a project, support has been lacking. Reports on the issue include: a 2011 review on the exposome and exposure science by Paul Lioy and Stephen Rappaport, "Exposure science and the exposome: an opportunity for coherence in the environmental health sciences" in the journal Environmental Health Perspectives. a 2012 report from the United States National Research Council "Exposure Science in the 21st Century: A Vision and A Strategy", outlining the challenges in systematic evaluations of the exposome. Related fields The concept of the exposome has contributed to the 2010 proposal of a new paradigm in disease phenotype, "the unique disease principle": Every individual has a unique disease process different from any other individual, considering uniqueness of the exposome and its unique influence on molecular pathologic processes including alterations in the interactome. This principle was first described in neoplastic diseases as "the unique tumor principle". Based on this unique disease principle, the interdisciplinary field of molecular pathological epidemiology (MPE) integrates molecular pathology and epidemiology. Socioeconomic drivers Global change is driven by many factors; however the five main drivers of global change are: population growth, economic growth, technological advances, attitudes, and institutions. These five main drivers of global change can stem from socioeconomic factors which in turn, these can be seen as drivers in their own regard.  Socioeconomic drivers of climate change can be triggered by a social or economic demand for resources such as a demand for timber or a demand for agricultural crops.  In tropical deforestation for instance, the main driver is economic opportunities that come the extraction of these resources and the conversion of this land to crop or rangelands. These drivers can be manifested at any level, from the global level demand for timber all the way to the household level. An example of how socioeconomic drivers affect climate change can be seen in the soy bean trading between Brazil and China. The trading of soy beans from to Brazil and China has grown immensely in the past few decades. This growth in trade between these two countries is stimulated by socioeconomic drivers. Some of the socioeconomic drivers in play here are the rising demand for Brazilian soy beans in China, the increase in land use change for soy bean production in Brazil, and the importance of strengthening foreign trade between the two countries. All of these socioeconomic drivers have implications in climate change. For instance, an increase in the development for soy bean croplands in Brazil means there needs to be more and more land made available for this resource. This causes the general land cover of forest to be converted into croplands which in its own regard has an impact on the environment. This example of land use change driven by a demand of a resource, isn't only happening in Brazil with soy bean production. Another example came from The Renewable Energy Directive 2009 Union when they mandated biofuel development for countries within their membership. With an international socioeconomic driver of increasing the production biofuels comes affects in land use in these countries. When agricultural cropland shift to bioenergy cropland the original crop supply decreases while the global market for this crop increases. This causes a cascading socioeconomic driver for the need for more agricultural croplands to support the growing demand. However, with the lack of available land from the crop substitution to biofuels, countries must look into areas further away to develop these original croplands. This causes spillover systems in countries where this new development takes place. For instance, African countries are converting savanna's into cropland and this all stems from the socioeconomic driver of wanting to develop biofuels. Furthermore, socioeconomic driver that cause land use change don't all occur at an international level. These drivers can be experienced all the way down to the household level. Crop substitution doesn't only come from biofuel shifts in agriculture, a big substitution came from Thailand when they switched the production of opium poppy plants to non-narcotic crops. This caused Thailand's agricultural sector to grow, but it caused global rippling effects (opium replacement). For instance, in Wolong China, locals use forests as fuelwood to cook and heat their homes. So, the socioeconomic driver in play here is the local demand for timber to support subsistence in this area. With this driver, locals are depleting their supply for fuelwood so they have to keep moving further away to extract this resource. This movement and demand for timber is in turn contributing to the loss of pandas in this area because their ecosystem is getting destroyed. However, when researching local trends the focus tends to be on outcomes instead of on how changes in the global drivers affect outcomes. With this being said, community level planning needs to be implemented when analyzing socioeconomic drivers of change. In conclusion, one can see how socioeconomic drivers at any level play a role in the consequences of human actions on the environment. These drivers all have cascading effects on land, humans, resources, and the environment as a whole. With this being said, humans need to fully understand how their socioeconomic drivers can change the way we live. For instance, going back to the soy bean example, when the supply can't meet the demand for soy beans the global market for this crop increases which then in turn affects countries that rely on this crop for a food source. These affects can cause a higher price for soy beans at their stores and markets or it can cause an overall lack of availability for this crop in importing countries. With both of these outcomes, the household level is being affected by a national level socioeconomic driver of an increased demand for Brazilian soy beans in China. From just this one example alone, one can see how socioeconomic drivers influence changes at a national level that then lead to more global, regional, communal, and household level changes. The main concept to take away from this is the idea that everything is connected and that our roles and choices as humans have major driving forces that impact our world in numerous ways.

Food chain

A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice), or decomposer (such as fungi or bacteria). It is not the same as a food web. A food chain depicts relations between species based on what they consume for energy in trophic levels, and they are most commonly quantified in length: the number of links between a trophic consumer and the base of the chain. Food chain studies play an important role in many biological studies. Food chain stability is very important for the survival of most species. When only one element is removed from the food chain it can result in extinction or immense decreases of survival of a species. Many food chains and food webs contain a keystone species, a species that has a large impact on the surrounding environment and that can directly affect the food chain. If a keystone species is removed it can set the entire food chain off balance. The efficiency of a food chain depends on the energy first consumed by the primary producers. This energy then moves through the trophic levels. History Food Chains were first discussed by al-Jahiz, a 10th century Arab philosopher. The modern concepts of food chains and food webs were introduced by Charles Elton. Food chain vs. food web A food chain differs from a food web as a food chain follows a direct linear pathway of consumption and energy transfer. Natural interconnections between food chains make a food web, which are non-linear and depict interconnecting pathways of consumption and energy transfer. Trophic levels Food chain models typically predict that communities are controlled by predators at the top and plants (autotrophs or producers) at the bottom. Thus, the foundation of the food chain typically consists of primary producers. Primary producers, or autotrophs, utilize energy derived from either sunlight or inorganic chemical compounds to create complex organic compounds, such as starch, for energy. Because the sun's light is necessary for photosynthesis, most life could not exist if the sun disappeared. Even so, it has recently been discovered that there are some forms of life, chemotrophs, that appear to gain all their metabolic energy from chemosynthesis driven by hydrothermal vents, thus showing that some life may not require solar energy to thrive. Chemosynthetic bacteria and archaea use hydrogen sulfide and methane from hydrothermal vents and cold seeps as an energy source (just as plants use sunlight) to produce carbohydrates; they form the base of the food chain in regions with little to no sunlight. Regardless of where the energy is obtained, a species that produces its own energy lies at the base of the food chain model, and is a critically important part of an ecosystem. Higher trophic levels cannot produce their own energy and so must consume producers or other life that itself consumes producers. In the higher trophic levels lies consumers (secondary consumers, tertiary consumers, etc.).Consumers are organisms that eat other organisms. All organisms in a food chain, except the first organism, are consumers. Secondary consumers eat and obtain energy from primary consumers, tertiary consumers eat and obtain energy from secondary consumers, etc. At the highest trophic level is typically an apex predator; a consumer with no natural predators in the food chain model. When any trophic level dies, detritivores and decomposers consume their organic material for energy and expel nutrients into the environment in their waste. Decomposers and detritivores break down the organic compounds into simple nutrients that are returned to the soil. These are the simple nutrients that plants require to create organic compounds. It is estimated that there are more than 100,000 different decomposers in existence. Models of trophic levels also often model energy transfer between trophic levels. Primary consumers get energy from the producer and pass it to the secondary and tertiary consumers. Studies Food chains are vital in ecotoxicology studies, which trace the pathways and biomagnification of environmental contaminants. It is also necessary to consider interactions amongst different trophic levels to predict community dynamics; food chains are often the base level for theory development of trophic levels and community/ecosystem investigations. Length The length of a food chain is a continuous variable providing a measure of the passage of energy and an index of ecological structure that increases through the linkages from the lowest to the highest trophic (feeding) levels. Food chains are often used in ecological modeling (such as a three-species food chain). They are simplified abstractions of real food webs, but complex in their dynamics and mathematical implications. In its simplest form, the length of a chain is the number of links between a trophic consumer and the base of the web. The mean chain length of an entire web is the arithmetic average of the lengths of all chains in the food web. The food chain is an energy source diagram. The food chain begins with a producer, which is eaten by a primary consumer. The primary consumer may be eaten by a secondary consumer, which in turn may be consumed by a tertiary consumer. The tertiary consumers may sometimes become prey to the top predators known as the quaternary consumers. For example, a food chain might start with a green plant as the producer, which is eaten by a snail, the primary consumer. The snail might then be the prey of a secondary consumer such as a frog, which itself may be eaten by a tertiary consumer such as a snake which in turn may be consumed by an eagle. This simple view of a food chain with fixed trophic levels within a species -species A is eaten by species B, B is eaten by C…- is often contrasted by the real situation in which the juveniles of a species belong to a lower trophic level than the adults, a situation more often seen in aquatic and amphibious environments, e.g., in insects and fishes. This complexity was denominated metaphoetesis by G. E. Hutchinson, 1959. Ecologists have formulated and tested hypotheses regarding the nature of ecological patterns associated with food chain length, such as length increasing with ecosystem volume, limited by the reduction of energy at each successive level, or reflecting habitat type. Food chain length is important because the amount of energy transferred decreases as trophic level increases; generally only ten percent of the total energy at one trophic level is passed to the next, as the remainder is used in the metabolic process. There are usually no more than five tropic levels in a food chain. Humans are able to receive more energy by going back a level in the chain and consuming the food before, for example getting more energy per pound from consuming a salad than an animal which ate lettuce. Keystone species A keystone species is a singular species within an ecosystem that others within the same ecosystem, or the entire ecosystem itself, rely upon.Keystone species' are so vital for an ecosystem that without their presence, an ecosystem could transform or stop existing entirely. One way keystone species impact an ecosystem is through their presence in an ecosystem's food web and, by extension, a food chain within said ecosystem. Sea otters, a keystone species in Pacific coastal regions, prey on sea urchins. Without the presence of sea otters, sea urchins practice destructive grazing on kelp populations which contributes to declines in coastal ecosystems within the northern pacific regions. The presence of sea otters controls sea urchin populations and helps maintain kelp forests, which are vital for other species within the ecosystem.

Natural resource

Natural resources are resources that are drawn from nature and used with few modifications. This includes the sources of valued characteristics such as commercial and industrial use, aesthetic value, scientific interest, and cultural value. On Earth, it includes sunlight, atmosphere, water, land, all minerals along with all vegetation, and wildlife. Natural resources are part of humanity's natural heritage or protected in nature reserves. Particular areas (such as the rainforest in Fatu-Hiva) often feature biodiversity and geodiversity in their ecosystems. Natural resources may be classified in different ways. Natural resources are materials and components (something that can be used) found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as freshwater, air, or any living organism such as a fish, or it may be transformed by extractivist industries into an economically useful form that must be processed to obtain the resource such as metal ores, rare-earth elements, petroleum, timber and most forms of energy. Some resources are renewable, which means that they can be used at a certain rate and natural processes will restore them. In contrast, many extractive industries rely heavily on non-renewable resources that can only be extracted once. Natural resource allocations can be at the centre of many economic and political confrontations both within and between countries. This is particularly true during periods of increasing scarcity and shortages (depletion and overconsumption of resources). Resource extraction is also a major source of human rights violations and environmental damage. The Sustainable Development Goals and other international development agendas frequently focus on creating more sustainable resource extraction, with some scholars and researchers focused on creating economic models, such as circular economy, that rely less on resource extraction, and more on reuse, recycling and renewable resources that can be sustainably managed. Classification There are various criteria for classifying natural resources. These include the source of origin, stages of development, renewability and ownership. Origin Biotic: Resources that originate from the biosphere and have life such as flora and fauna, fisheries, livestock, etc. Fossil fuels such as coal and petroleum are also included in this category because they are formed from decayed organic matter. Abiotic: Resources that originate from non-living and inorganic material. These include land, fresh water, air, rare-earth elements, and heavy metals including ores, such as gold, iron, copper, silver, etc. Stage of development Potential resources: Resources that are known to exist, but have not been utilized yet. These may be used in the future. For example, petroleum in sedimentary rocks that, until extracted and put to use, remains a potential resource. Actual resources: Resources that have been surveyed, quantified and qualified, and are currently used in development. These are typically dependent on technology and the level of their feasibility, wood processing for example. Reserves: The part of an actual resource that can be developed profitably in the future. Stocks: Resources that have been surveyed, but cannot be used due to lack of technology, hydrogen vehicles for example. Renewability/exhaustibility Renewable resources: These resources can be replenished naturally. Some of these resources, like solar energy, air, wind, water, etc. are continuously available and their quantities are not noticeably affected by human consumption. Though many renewable resources do not have such a rapid recovery rate, these resources are susceptible to depletion by over-use. Resources from a human use perspective are classified as renewable so long as the rate of replenishment/recovery exceeds that of the rate of consumption. They replenish easily compared to non-renewable resources. Non-renewable resources: These resources are formed over a long geological time period in the environment and cannot be renewed easily. Minerals are the most common resource included in this category. From the human perspective, resources are non-renewable when their rate of consumption exceeds the rate of replenishment/recovery; a good example of this is fossil fuels, which are in this category because their rate of formation is extremely slow (potentially millions of years), meaning they are considered non-renewable. Some resources naturally deplete in amount without human interference, the most notable of these being radio-active elements such as uranium, which naturally decay into heavy metals. Of these, the metallic minerals can be re-used by recycling them, but coal and petroleum cannot be recycled. Ownership Individual resources: Resources owned privately by individuals. These include plots, houses, plantations, pastures, ponds, etc. Community resources: Resources which are accessible to all the members of a community. E.g.: Cemeteries National resources: Resources that belong to the nation. The nation has legal powers to acquire them for public welfare. These also include minerals, forests and wildlife within the political boundaries and Exclusive economic zone. International resources: These resources are regulated by international organizations. E.g.: International waters. Extraction Resource extraction involves any activity that withdraws resources from nature. This can range in scale from the traditional use of preindustrial societies to global industry. Extractive industries are, along with agriculture, the basis of the primary sector of the economy. Extraction produces raw material, which is then processed to add value. Examples of extractive industries are hunting, trapping, mining, oil and gas drilling, and forestry. Natural resources can add substantial amounts to a country's wealth; however, a sudden inflow of money caused by a resource boom can create social problems including inflation harming other industries ("Dutch disease") and corruption, leading to inequality and underdevelopment, this is known as the "resource curse". Extractive industries represent a large growing activity in many less-developed countries but the wealth generated does not always lead to sustainable and inclusive growth. People often accuse extractive industry businesses as acting only to maximize short-term value, implying that less-developed countries are vulnerable to powerful corporations. Alternatively, host governments are often assumed to be only maximizing immediate revenue. Researchers argue there are areas of common interest where development goals and business cross. These present opportunities for international governmental agencies to engage with the private sector and host governments through revenue management and expenditure accountability, infrastructure development, employment creation, skills and enterprise development, and impacts on children, especially girls and women. A strong civil society can play an important role in ensuring the effective management of natural resources. Norway can serve as a role model in this regard as it has good institutions and open and dynamic public debate with strong civil society actors that provide an effective checks and balances system for the government's management of extractive industries, such as the Extractive Industries Transparency Initiative (EITI), a global standard for the good governance of oil, gas and mineral resources. It seeks to address the key governance issues in the extractive sectors. However, in countries that do not have a very strong and unified society, meaning that there are dissidents who are not as happy with the government as in Norway's case, natural resources can actually be a factor in whether a civil war starts and how long the war lasts. Depletion In recent years, the depletion of natural resources has become a major focus of governments and organizations such as the United Nations (UN). This is evident in the UN's Agenda 21 Section Two, which outlines the necessary steps for countries to take to sustain their natural resources. The depletion of natural resources is considered a sustainable development issue. The term sustainable development has many interpretations, most notably the Brundtland Commission's 'to ensure that it meets the needs of the present without compromising the ability of future generations to meet their own needs'; however, in broad terms it is balancing the needs of the planet's people and species now and in the future. In regards to natural resources, depletion is of concern for sustainable development as it has the ability to degrade current environments and the potential to impact the needs of future generations. Depletion of natural resources is associated with social inequity. Considering most biodiversity are located in developing countries, depletion of this resource could result in losses of ecosystem services for these countries. Some view this depletion as a major source of social unrest and conflicts in developing nations. At present, there is a particular concern for rainforest regions that hold most of the Earth's biodiversity. According to Nelson, deforestation and degradation affect 8.5% of the world's forests with 30% of the Earth's surface already cropped. If we consider that 80% of people rely on medicines obtained from plants and of the world's prescription medicines have ingredients taken from plants, loss of the world's rainforests could result in a loss of finding more potential life-saving medicines. The depletion of natural resources is caused by 'direct drivers of change' such as mining, petroleum extraction, fishing, and forestry as well as 'indirect drivers of change' such as demography (e.g. population growth), economy, society, politics, and technology. The current practice of agriculture is another factor causing depletion of natural resources. For example, the depletion of nutrients in the soil due to excessive use of nitrogen and desertification. The depletion of natural resources is a continuing concern for society. This is seen in the cited quote given by Theodore Roosevelt, a well-known conservationist and former United States president, who was opposed to unregulated natural resource extraction. Protection In 1982, the United Nations developed the World Charter for Nature, which recognized the need to protect nature from further depletion due to human activity. It states that measures must be taken at all societal levels, from international to individual, to protect nature. It outlines the need for sustainable use of natural resources and suggests that the protection of resources should be incorporated into national and international systems of law. To look at the importance of protecting natural resources further, the World Ethic of Sustainability, developed by the IUCN, WWF and the UNEP in 1990, set out eight values for sustainability, including the need to protect natural resources from depletion. Since the development of these documents, many measures have been taken to protect natural resources including establishment of the scientific field and practice of conservation biology and habitat conservation, respectively. Conservation biology is the scientific study of the nature and status of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction. It is an interdisciplinary subject drawing on science, economics and the practice of natural resource management. The term conservation biology was introduced as the title of a conference held at the University of California, San Diego, in La Jolla, California, in 1978, organized by biologists Bruce A. Wilcox and Michael E. Soulé. Habitat conservation is a type of land management that seeks to conserve, protect and restore habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range. Management Natural resource management is a discipline in the management of natural resources such as land, water, soil, plants, and animals—with a particular focus on how management affects quality of life for present and future generations. Hence, sustainable development is followed according to the judicious use of resources to supply present and future generations. The disciplines of fisheries, forestry, and wildlife are examples of large subdisciplines of natural resource management. Management of natural resources involves identifying who has the right to use the resources and who does not to define the management boundaries of the resource. The resources may be managed by the users according to the rules governing when and how the resource is used depending on local condition or the resources may be managed by a governmental organization or other central authority. A "...successful management of natural resources depends on freedom of speech, a dynamic and wide-ranging public debate through multiple independent media channels and an active civil society engaged in natural resource issues..." because of the nature of the shared resources, the individuals who are affected by the rules can participate in setting or changing them. The users have rights to devise their own management institutions and plans under the recognition by the government. The right to resources includes land, water, fisheries, and pastoral rights. The users or parties accountable to the users have to actively monitor and ensure the utilisation of the resource compliance with the rules and impose penalties on those people who violate the rules. These conflicts are resolved quickly and efficiently by the local institution according to the seriousness and context of the offense. The global science-based platform to discuss natural resources management is the World Resources Forum, based in Switzerland.

Energy development

Energy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include the production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted. Energy conservation and efficiency measures reduce the demand for energy development, and can have benefits to society with improvements to environmental issues. Societies use energy for transportation, manufacturing, illumination, heating and air conditioning, and communication, for industrial, commercial, and domestic purposes. Energy resources may be classified as primary resources, where the resource can be used in substantially its original form, or as secondary resources, where the energy source must be converted into a more conveniently usable form. Non-renewable resources are significantly depleted by human use, whereas renewable resources are produced by ongoing processes that can sustain indefinite human exploitation. Thousands of people are employed in the energy industry. The conventional industry comprises the petroleum industry, the natural gas industry, the electrical power industry, and the nuclear industry. New energy industries include the renewable energy industry, comprising alternative and sustainable manufacture, distribution, and sale of alternative fuels. Classification of resources Energy resources may be classified as primary resources, suitable for end use without conversion to another form, or secondary resources, where the usable form of energy required substantial conversion from a primary source. Examples of primary energy resources are wind power, solar power, wood fuel, fossil fuels such as coal, oil and natural gas, and uranium. Secondary resources are those such as electricity, hydrogen, or other synthetic fuels. Another important classification is based on the time required to regenerate an energy resource. "Renewable" resources are those that recover their capacity in a time significant by human needs. Examples are hydroelectric power or wind power, when the natural phenomena that are the primary source of energy are ongoing and not depleted by human demands. Non-renewable resources are those that are significantly depleted by human usage and that will not recover their potential significantly during human lifetimes. An example of a non-renewable energy source is coal, which does not form naturally at a rate that would support human use. Fossil fuels Fossil fuel (primary non-renewable fossil) sources burn coal or hydrocarbon fuels, which are the remains of the decomposition of plants and animals. There are three main types of fossil fuels: coal, petroleum, and natural gas. Another fossil fuel, liquefied petroleum gas (LPG), is principally derived from the production of natural gas. Heat from burning fossil fuel is used either directly for space heating and process heating, or converted to mechanical energy for vehicles, industrial processes, or electrical power generation. These fossil fuels are part of the carbon cycle and allow solar energy stored in the fuel to be released. The use of fossil fuels in the 18th and 19th century set the stage for the Industrial Revolution. Fossil fuels make up the bulk of the world's current primary energy sources. In 2005, 81% of the world's energy needs was met from fossil sources. The technology and infrastructure for the use of fossil fuels already exist. Liquid fuels derived from petroleum deliver much usable energy per unit of weight or volume, which is advantageous when compared with lower energy density sources such as batteries. Fossil fuels are currently economical for decentralized energy use. Energy dependence on imported fossil fuels creates energy security risks for dependent countries. Oil dependence in particular has led to war, funding of radicals, monopolization, and socio-political instability. Fossil fuels are non-renewable resources, which will eventually decline in production and become exhausted. While the processes that created fossil fuels are ongoing, fuels are consumed far more quickly than the natural rate of replenishment. Extracting fuels becomes increasingly costly as society consumes the most accessible fuel deposits. Extraction of fossil fuels results in environmental degradation, such as the strip mining and mountaintop removal for coal. Fuel efficiency is a form of thermal efficiency, meaning the efficiency of a process that converts chemical potential energy contained in a carrier fuel into kinetic energy or work. The fuel economy is the energy efficiency of a particular vehicle, is given as a ratio of distance travelled per unit of fuel consumed. Weight-specific efficiency (efficiency per unit weight) may be stated for freight, and passenger-specific efficiency (vehicle efficiency) per passenger. The inefficient atmospheric combustion (burning) of fossil fuels in vehicles, buildings, and power plants contributes to urban heat islands. Conventional production of oil peaked, conservatively, between 2007 and 2010. In 2010, it was estimated that an investment of $8 trillion in non-renewable resources would be required to maintain current levels of production for 25 years. In 2010, governments subsidized fossil fuels by an estimated $500 billion a year. Fossil fuels are also a source of greenhouse gas emissions, leading to concerns about global warming if consumption is not reduced. The combustion of fossil fuels leads to the release of pollution into the atmosphere. The fossil fuels are mainly carbon compounds. During combustion, carbon dioxide is released, and also nitrogen oxides, soot and other fine particulates. The carbon dioxide is the main contributor to recent climate change. Other emissions from fossil fuel power station include sulphur dioxide, carbon monoxide (CO), hydrocarbons, volatile organic compounds (VOC), mercury, arsenic, lead, cadmium, and other heavy metals including traces of uranium. A typical coal plant generates billions of kilowatt hours of electrical power per year. Nuclear Fission Nuclear power is the use of nuclear fission to generate useful heat and electricity. Fission of uranium produces nearly all economically significant nuclear power. Radioisotope thermoelectric generators form a very small component of energy generation, mostly in specialized applications such as deep space vehicles. Nuclear power plants, excluding naval reactors, provided about 5.7% of the world's energy and 13% of the world's electricity in 2012. In 2013, the IAEA report that there are 437 operational nuclear power reactors, in 31 countries, although not every reactor is producing electricity. In addition, there are approximately 140 naval vessels using nuclear propulsion in operation, powered by some 180 reactors. As of 2013, attaining a net energy gain from sustained nuclear fusion reactions, excluding natural fusion power sources such as the Sun, remains an ongoing area of international physics and engineering research. More than 60 years after the first attempts, commercial fusion power production remains unlikely before 2050. There is an ongoing debate about nuclear power. Proponents, such as the World Nuclear Association, the IAEA and Environmentalists for Nuclear Energy contend that nuclear power is a safe, sustainable energy source that reduces carbon emissions. Opponents contend that nuclear power poses many threats to people and the environment. Nuclear power plant accidents include the Chernobyl disaster (1986), Fukushima Daiichi nuclear disaster (2011), and the Three Mile Island accident (1979). There have also been some nuclear submarine accidents. In terms of lives lost per unit of energy generated, analysis has determined that nuclear power has caused less fatalities per unit of energy generated than the other major sources of energy generation. Energy production from coal, petroleum, natural gas and hydropower has caused a greater number of fatalities per unit of energy generated due to air pollution and energy accident effects. However, the economic costs of nuclear power accidents is high, and meltdowns can take decades to clean up. The human costs of evacuations of affected populations and lost livelihoods is also significant. Comparing Nuclear's latent cancer deaths, such as cancer with other energy sources immediate deaths per unit of energy generated(GWeyr). This study does not include fossil fuel related cancer and other indirect deaths created by the use of fossil fuel consumption in its "severe accident" classification, which would be an accident with more than 5 fatalities. As of 2012, according to the IAEA, worldwide there were 68 civil nuclear power reactors under construction in 15 countries, approximately 28 of which in the People's Republic of China (PRC), with the most recent nuclear power reactor, as of May 2013, to be connected to the electrical grid, occurring on February 17, 2013, in Hongyanhe Nuclear Power Plant in the PRC. In the United States, two new Generation III reactors are under construction at Vogtle. U.S. nuclear industry officials expect five new reactors to enter service by 2020, all at existing plants. In 2013, four aging, uncompetitive, reactors were permanently closed. Recent experiments in extraction of uranium use polymer ropes that are coated with a substance that selectively absorbs uranium from seawater. This process could make the considerable volume of uranium dissolved in seawater exploitable for energy production. Since ongoing geologic processes carry uranium to the sea in amounts comparable to the amount that would be extracted by this process, in a sense the sea-borne uranium becomes a sustainable resource. Nuclear power is a low carbon power generation method of producing electricity, with an analysis of the literature on its total life cycle emission intensity finding that it is similar to renewable sources in a comparison of greenhouse gas (GHG) emissions per unit of energy generated. Since the 1970s, nuclear fuel has displaced about 64 gigatonnes of carbon dioxide equivalent (GtCO2-eq) greenhouse gases, that would have otherwise resulted from the burning of oil, coal or natural gas in fossil-fuel power stations. Nuclear power phase-out and pull-backs Japan's 2011 Fukushima Daiichi nuclear accident, which occurred in a reactor design from the 1960s, prompted a rethink of nuclear safety and nuclear energy policy in many countries. Germany decided to close all its reactors by 2022, and Italy has banned nuclear power. Following Fukushima, in 2011 the International Energy Agency halved its estimate of additional nuclear generating capacity to be built by 2035. Fukushima Following the 2011 Fukushima Daiichi nuclear disaster – the second worst nuclear incident, that displaced 50,000 households after radioactive material leaked into the air, soil and sea, and with subsequent radiation checks leading to bans on some shipments of vegetables and fish – a global public support survey by Ipsos (2011) for energy sources was published and nuclear fission was found to be the least popular Fission economics The economics of new nuclear power plants is a controversial subject, since there are diverging views on this topic, and multibillion-dollar investments ride on the choice of an energy source. Nuclear power plants typically have high capital costs for building the plant, but low direct fuel costs. In recent years there has been a slowdown of electricity demand growth and financing has become more difficult, which affects large projects such as nuclear reactors, with very large upfront costs and long project cycles which carry a large variety of risks. In Eastern Europe, a number of long-established projects are struggling to find finance, notably Belene in Bulgaria and the additional reactors at Cernavoda in Romania, and some potential backers have pulled out. Where cheap gas is available and its future supply relatively secure, this also poses a major problem for nuclear projects. Analysis of the economics of nuclear power must take into account who bears the risks of future uncertainties. To date all operating nuclear power plants were developed by state-owned or regulated utility monopolies where many of the risks associated with construction costs, operating performance, fuel price, and other factors were borne by consumers rather than suppliers. Many countries have now liberalized the electricity market where these risks, and the risk of cheaper competitors emerging before capital costs are recovered, are borne by plant suppliers and operators rather than consumers, which leads to a significantly different evaluation of the economics of new nuclear power plants. Costs Costs are likely to go up for currently operating and new nuclear power plants, due to increased requirements for on-site spent fuel management and elevated design basis threats. While first of their kind designs, such as the EPRs under construction are behind schedule and over-budget, of the seven South Korean APR-1400s presently under construction worldwide, two are in S.Korea at the Hanul Nuclear Power Plant and four are at the largest nuclear station construction project in the world as of 2016, in the United Arab Emirates at the planned Barakah nuclear power plant. The first reactor, Barakah-1 is 85% completed and on schedule for grid-connection during 2017. Two of the four EPRs under construction (in Finland and France) are significantly behind schedule and substantially over cost. Renewable sources Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services. Including traditional biomass usage, about 19% of global energy consumption is accounted for by renewable resources. Wind powered energy production is being turned to as a prominent renewable energy source, increasing global wind power capacity by 12% in 2021. While not the case for all countries, 58% of sample countries linked renewable energy consumption to have a positive impact on economic growth. At the national level, at least 30 nations around the world already have renewable energy contributing more than 20% of energy supply. National renewable energy markets are projected to continue to grow strongly in the coming decade and beyond.[76] Unlike other energy sources, renewable energy sources are not as restricted by geography. Additionally deployment of renewable energy is resulting in economic benefits as well as combating climate change. Rural electrification has been researched on multiple sites and positive effects on commercial spending, appliance use, and general activities requiring electricity as energy. Renewable energy growth in at least 38 countries has been driven by the high electricity usage rates. International support for promoting renewable sources like solar and wind have continued grow. While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. To ensure human development continues sustainably, governments around the world are beginning to research potential ways to implement renewable sources into their countries and economies. For example, the UK Government’s Department for Energy and Climate Change 2050 Pathways created a mapping technique to educate the public on land competition between energy supply technologies. This tool provides users the ability to understand what the limitations and potential their surrounding land and country has in terms of energy production. Hydroelectricity Hydroelectricity is electric power generated by hydropower; the force of falling or flowing water. In 2015 hydropower generated 16.6% of the world's total electricity and 70% of all renewable electricity and was expected to increase about 3.1% each year for the following 25 years. Hydropower is produced in 150 countries, with the Asia-Pacific region generating 32 percent of global hydropower in 2010. China is the largest hydroelectricity producer, with 721 terawatt-hours of production in 2010, representing around 17 percent of domestic electricity use. There are now three hydroelectricity plants larger than 10 GW: the Three Gorges Dam in China, Itaipu Dam across the Brazil/Paraguay border, and Guri Dam in Venezuela. The cost of hydroelectricity is relatively low, making it a competitive source of renewable electricity. The average cost of electricity from a hydro plant larger than 10 megawatts is 3 to 5 U.S. cents per kilowatt-hour. Hydro is also a flexible source of electricity since plants can be ramped up and down very quickly to adapt to changing energy demands. However, damming interrupts the flow of rivers and can harm local ecosystems, and building large dams and reservoirs often involves displacing people and wildlife. Once a hydroelectric complex is constructed, the project produces no direct waste, and has a considerably lower output level of the greenhouse gas carbon dioxide than fossil fuel powered energy plants. Wind Wind power harnesses the power of the wind to propel the blades of wind turbines. These turbines cause the rotation of magnets, which creates electricity. Wind towers are usually built together on wind farms. There are offshore and onshore wind farms. Global wind power capacity has expanded rapidly to 336 GW in June 2014, and wind energy production was around 4% of total worldwide electricity usage, and growing rapidly. Wind power is widely used in Europe, Asia, and the United States. Several countries have achieved relatively high levels of wind power penetration, such as 21% of stationary electricity production in Denmark, 18% in Portugal, 16% in Spain, 14% in Ireland, and 9% in Germany in 2010. By 2011, at times over 50% of electricity in Germany and Spain came from wind and solar power. As of 2011, 83 countries around the world are using wind power on a commercial basis. Many of the world's largest onshore wind farms are located in the United States, China, and India. Most of the world's largest offshore wind farms are located in Denmark, Germany and the United Kingdom. The two largest offshore wind farm are currently the 630 MW London Array and Gwynt y Môr. Solar Biofuels A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms. Examples of this carbon fixation occur in plants and microalgae. These fuels are made by a biomass conversion (biomass refers to recently living organisms, most often referring to plants or plant-derived materials). This biomass can be converted to convenient energy containing substances in three different ways: thermal conversion, chemical conversion, and biochemical conversion. This biomass conversion can result in fuel in solid, liquid, or gas form. This new biomass can be used for biofuels. Biofuels have increased in popularity because of rising oil prices and the need for energy security. Bioethanol is an alcohol made by fermentation, mostly from carbohydrates produced in sugar or starch crops such as corn or sugarcane. Cellulosic biomass, derived from non-food sources, such as trees and grasses, is also being developed as a feedstock for ethanol production. Ethanol can be used as a fuel for vehicles in its pure form, but it is usually used as a gasoline additive to increase octane and improve vehicle emissions. Bioethanol is widely used in the USA and in Brazil. Current plant design does not provide for converting the lignin portion of plant raw materials to fuel components by fermentation. Biodiesel is made from vegetable oils and animal fats. Biodiesel can be used as a fuel for vehicles in its pure form, but it is usually used as a diesel additive to reduce levels of particulates, carbon monoxide, and hydrocarbons from diesel-powered vehicles. Biodiesel is produced from oils or fats using transesterification and is the most common biofuel in Europe. However, research is underway on producing renewable fuels from decarboxylation In 2010, worldwide biofuel production reached 105 billion liters (28 billion gallons US), up 17% from 2009, and biofuels provided 2.7% of the world's fuels for road transport, a contribution largely made up of ethanol and biodiesel. Global ethanol fuel production reached 86 billion liters (23 billion gallons US) in 2010, with the United States and Brazil as the world's top producers, accounting together for 90% of global production. The world's largest biodiesel producer is the European Union, accounting for 53% of all biodiesel production in 2010. As of 2011, mandates for blending biofuels exist in 31 countries at the national level and in 29 states or provinces. The International Energy Agency has a goal for biofuels to meet more than a quarter of world demand for transportation fuels by 2050 to reduce dependence on petroleum and coal. Geothermal Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth's crust originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%). The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface. The adjective geothermal originates from the Greek roots γη (ge), meaning earth, and θερμος (thermos), meaning hot. Earth's internal heat is thermal energy generated from radioactive decay and continual heat loss from Earth's formation. Temperatures at the core-mantle boundary may reach over 4000 °C (7,200 °F). The high temperature and pressure in Earth's interior cause some rock to melt and solid mantle to behave plastically, resulting in portions of mantle convecting upward since it is lighter than the surrounding rock. Rock and water is heated in the crust, sometimes up to 370 °C (700 °F). From hot springs, geothermal energy has been used for bathing since Paleolithic times and for space heating since ancient Roman times, but it is now better known for electricity generation. Worldwide, 11,400 megawatts (MW) of geothermal power is online in 24 countries in 2012. An additional 28 gigawatts of direct geothermal heating capacity is installed for district heating, space heating, spas, industrial processes, desalination and agricultural applications in 2010. Geothermal power is cost effective, reliable, sustainable, and environmentally friendly, but has historically been limited to areas near tectonic plate boundaries. Recent technological advances have dramatically expanded the range and size of viable resources, especially for applications such as home heating, opening a potential for widespread exploitation. Geothermal wells release greenhouse gases trapped deep within the earth, but these emissions are much lower per energy unit than those of fossil fuels. As a result, geothermal power has the potential to help mitigate global warming if widely deployed in place of fossil fuels. The Earth's geothermal resources are theoretically more than adequate to supply humanity's energy needs, but only a very small fraction may be profitably exploited. Drilling and exploration for deep resources is very expensive. Forecasts for the future of geothermal power depend on assumptions about technology, energy prices, subsidies, and interest rates. Pilot programs like EWEB's customer opt in Green Power Program show that customers would be willing to pay a little more for a renewable energy source like geothermal. But as a result of government assisted research and industry experience, the cost of generating geothermal power has decreased by 25% over the past two decades. In 2001, geothermal energy cost between two and ten US cents per kWh. Oceanic Marine Renewable Energy (MRE) or marine power (also sometimes referred to as ocean energy, ocean power, or marine and hydrokinetic energy) refers to the energy carried by the mechanical energy of ocean waves, currents, and tides, shifts in salinity gradients, and ocean temperature differences. MRE has the potential to become a reliable and renewable energy source because of the cyclical nature of the oceans. The movement of water in the world's oceans creates a vast store of kinetic energy or energy in motion. This energy can be harnessed to generate electricity to power homes, transport, and industries. The term marine energy encompasses both wave power, i.e. power from surface waves, and tidal power, i.e. obtained from the kinetic energy of large bodies of moving water. Offshore wind power is not a form of marine energy, as wind power is derived from the wind, even if the wind turbines are placed over water. The oceans have a tremendous amount of energy and are close to many if not most concentrated populations. Ocean energy has the potential to provide a substantial amount of new renewable energy around the world. Marine energy technology is in its first stage of development. To be developed, MRE needs efficient methods of storing, transporting, and capturing ocean power, so it can be used where needed. Over the past year, countries around the world have started implementing market strategies for MRE to commercialize. Canada and China introduced incentives, such as feed-in tariffs (FiTs), which are above-market prices for MRE that allow investors and project developers a stable income. Other financial strategies consist of subsidies, grants, and funding from public-private partnerships (PPPs). China alone approved 100 ocean projects in 2019. Portugal and Spain recognize the potential of MRE in accelerating decarbonization, which is fundamental to meeting the goals of the Paris Agreement. Both countries are focusing on solar and offshore wind auctions to attract private investment, ensure cost-effectiveness, and accelerate MRE growth. Ireland sees MRE as a key component to reduce its carbon footprint. The Offshore Renewable Energy Development Plan (OREDP) supports the exploration and development of the country's significant offshore energy potential. Additionally, Ireland has implemented the Renewable Electricity Support Scheme (RESS) which includes auctions designed to provide financial support for communities, increase technology diversity, and guarantee energy security. However, while research is increasing, there have been concerns associated with threats to marine mammals, habitats, and potential changes to ocean currents. MRE can be a renewable energy source for coastal communities helping their transition from fossil fuel, but researchers are calling for a better understanding of its environmental impacts. Because ocean-energy areas are often isolated from both fishing and sea traffic, these zones may provide shelter from humans and predators for some marine species. MRE devices can be an ideal home for many fish, crayfish, mollusks, and barnacles; and may also indirectly affect seabirds, and marine mammals because they feed on those species. Similarly, such areas may create an "artificial reef effect" by boosting biodiversity nearby. Noise pollution generated from the technology is limited, also causing fish and mammals living in the area of the installation to return. In the most recent State of Science Report about MRE, the authors claim that there is no evidence for fish, mammals, or seabirds to be injured by either collision, noise pollution, or the electromagnetic field. The uncertainty of its environmental impact comes from the low quantity of MRE devices in the ocean today where data is collected. 100% renewable energy The incentive to use 100% renewable energy, for electricity, transport, or even total primary energy supply globally, has been motivated by global warming and other ecological as well as economic concerns. Renewable energy use has grown much faster than anyone anticipated. The Intergovernmental Panel on Climate Change has said that there are few fundamental technological limits to integrating a portfolio of renewable energy technologies to meet most of total global energy demand. At the national level, at least 30 nations around the world already have renewable energy contributing more than 20% of energy supply. Also, Stephen W. Pacala and Robert H. Socolow have developed a series of "stabilization wedges" that can allow us to maintain our quality of life while avoiding catastrophic climate change, and "renewable energy sources," in aggregate, constitute the largest number of their "wedges." Mark Z. Jacobson says producing all new energy with wind power, solar power, and hydropower by 2030 is feasible and existing energy supply arrangements could be replaced by 2050. Barriers to implementing the renewable energy plan are seen to be "primarily social and political, not technological or economic". Jacobson says that energy costs with a wind, solar, water system should be similar to today's energy costs. Similarly, in the United States, the independent National Research Council has noted that "sufficient domestic renewable resources exist to allow renewable electricity to play a significant role in future electricity generation and thus help confront issues related to climate change, energy security, and the escalation of energy costs ... Renewable energy is an attractive option because renewable resources available in the United States, taken collectively, can supply significantly larger amounts of electricity than the total current or projected domestic demand." . Critics of the "100% renewable energy" approach include Vaclav Smil and James E. Hansen. Smil and Hansen are concerned about the variable output of solar and wind power, but Amory Lovins argues that the electricity grid can cope, just as it routinely backs up nonworking coal-fired and nuclear plants with working ones. Google spent $30 million on their "Renewable Energy Cheaper than Coal" project to develop renewable energy and stave off catastrophic climate change. The project was cancelled after concluding that a best-case scenario for rapid advances in renewable energy could only result in emissions 55 percent below the fossil fuel projections for 2050. Increased energy efficiency Although increasing the efficiency of energy use is not energy development per se, it may be considered under the topic of energy development since it makes existing energy sources available to do work. Efficient energy use reduces the amount of energy required to provide products and services. For example, insulating a home allows a building to use less heating and cooling energy to maintain a comfortable temperature. Installing fluorescent lamps or natural skylights reduces the amount of energy required for illumination compared to incandescent light bulbs. Compact fluorescent lights use two-thirds less energy and may last 6 to 10 times longer than incandescent lights. Improvements in energy efficiency are most often achieved by adopting an efficient technology or production process. Reducing energy use may save consumers money, if the energy savings offsets the cost of an energy efficient technology. Reducing energy use reduces emissions. According to the International Energy Agency, improved energy efficiency in buildings, industrial processes and transportation could reduce the global energy demand in 2050 to around 8% smaller than today, but serving an economy more than twice as big and a population of about 2  billion more people. Energy efficiency and renewable energy are said to be the twin pillars of sustainable energy policy. In many countries energy efficiency is also seen to have a national security benefit because it can be used to reduce the level of energy imports from foreign countries and may slow down the rate at which domestic energy resources are depleted. It's been discovered "that for OECD countries, wind, geothermal, hydro and nuclear have the lowest hazard rates among energy sources in production". Transmission While new sources of energy are only rarely discovered or made possible by new technology, distribution technology continually evolves. The use of fuel cells in cars, for example, is an anticipated delivery technology. This section presents the various delivery technologies that have been important to historic energy development. They all rely in way on the energy sources listed in the previous section. Shipping and pipelines Coal, petroleum and their derivatives are delivered by boat, rail, or road. Petroleum and natural gas may also be delivered by pipeline, and coal via a Slurry pipeline. Fuels such as gasoline and LPG may also be delivered via aircraft. Natural gas pipelines must maintain a certain minimum pressure to function correctly. The higher costs of ethanol transportation and storage are often prohibitive. Wired energy transfer Electricity grids are the networks used to transmit and distribute power from production source to end user, when the two may be hundreds of kilometres away. Sources include electrical generation plants such as a nuclear reactor, coal burning power plant, etc. A combination of sub-stations and transmission lines are used to maintain a constant flow of electricity. Grids may suffer from transient blackouts and brownouts, often due to weather damage. During certain extreme space weather events solar wind can interfere with transmissions. Grids also have a predefined carrying capacity or load that cannot safely be exceeded. When power requirements exceed what's available, failures are inevitable. To prevent problems, power is then rationed. Industrialised countries such as Canada, the US, and Australia are among the highest per capita consumers of electricity in the world, which is possible thanks to a widespread electrical distribution network. The US grid is one of the most advanced, although infrastructure maintenance is becoming a problem. CurrentEnergy provides a realtime overview of the electricity supply and demand for California, Texas, and the Northeast of the US. African countries with small scale electrical grids have a correspondingly low annual per capita usage of electricity. One of the most powerful power grids in the world supplies power to the state of Queensland, Australia. Wireless energy transfer Wireless power transfer is a process whereby electrical energy is transmitted from a power source to an electrical load that does not have a built-in power source, without the use of interconnecting wires. Currently available technology is limited to short distances and relatively low power level. Orbiting solar power collectors would require wireless transmission of power to Earth. The proposed method involves creating a large beam of microwave-frequency radio waves, which would be aimed at a collector antenna site on the Earth. Formidable technical challenges exist to ensure the safety and profitability of such a scheme. Storage Energy storage is accomplished by devices or physical media that store energy to perform useful operation at a later time. A device that stores energy is sometimes called an accumulator. All forms of energy are either potential energy (e.g. Chemical, gravitational, electrical energy, temperature differential, latent heat, etc.) or kinetic energy (e.g. momentum). Some technologies provide only short-term energy storage, and others can be very long-term such as power to gas using hydrogen or methane and the storage of heat or cold between opposing seasons in deep aquifers or bedrock. A wind-up clock stores potential energy (in this case mechanical, in the spring tension), a battery stores readily convertible chemical energy to operate a mobile phone, and a hydroelectric dam stores energy in a reservoir as gravitational potential energy. Ice storage tanks store ice (thermal energy in the form of latent heat) at night to meet peak demand for cooling. Fossil fuels such as coal and gasoline store ancient energy derived from sunlight by organisms that later died, became buried and over time were then converted into these fuels. Even food (which is made by the same process as fossil fuels) is a form of energy stored in chemical form. History Since prehistory, when humanity discovered fire to warm up and roast food, through the Middle Ages in which populations built windmills to grind the wheat, until the modern era in which nations can get electricity splitting the atom. Man has sought endlessly for energy sources. Except nuclear, geothermal and tidal, all other energy sources are from current solar isolation or from fossil remains of plant and animal life that relied upon sunlight. Ultimately, solar energy itself is the result of the Sun's nuclear fusion. Geothermal power from hot, hardened rock above the magma of the Earth's core is the result of the decay of radioactive materials present beneath the Earth's crust, and nuclear fission relies on man-made fission of heavy radioactive elements in the Earth's crust; in both cases these elements were produced in supernova explosions before the formation of the Solar System. Since the beginning of the Industrial Revolution, the question of the future of energy supplies has been of interest. In 1865, William Stanley Jevons published The Coal Question in which he saw that the reserves of coal were being depleted and that oil was an ineffective replacement. In 1914, U.S. Bureau of Mines stated that the total production was . In 1956, Geophysicist M. King Hubbert deduces that U.S. oil production would peak between 1965 and 1970 and that oil production will peak "within half a century" on the basis of 1956 data. In 1989, predicted peak by Colin Campbell In 2004, OPEC estimated, with substantial investments, it would nearly double oil output by 2025 Sustainability The environmental movement has emphasized sustainability of energy use and development. Renewable energy is sustainable in its production; the available supply will not be diminished for the foreseeable future - millions or billions of years. "Sustainability" also refers to the ability of the environment to cope with waste products, especially air pollution. Sources which have no direct waste products (such as wind, solar, and hydropower) are brought up on this point. With global demand for energy growing, the need to adopt various energy sources is growing. Energy conservation is an alternative or complementary process to energy development. It reduces the demand for energy by using it efficiently. Resilience Some observers contend that idea of "energy independence" is an unrealistic and opaque concept. The alternative offer of "energy resilience" is a goal aligned with economic, security, and energy realities. The notion of resilience in energy was detailed in the 1982 book Brittle Power: Energy Strategy for National Security. The authors argued that simply switching to domestic energy would not be secure inherently because the true weakness is the often interdependent and vulnerable energy infrastructure of a country. Key aspects such as gas lines and the electrical power grid are often centralized and easily susceptible to disruption. They conclude that a "resilient energy supply" is necessary for both national security and the environment. They recommend a focus on energy efficiency and renewable energy that is decentralized. In 2008, former Intel Corporation Chairman and CEO Andrew Grove looked to energy resilience, arguing that complete independence is unfeasible given the global market for energy. He describes energy resilience as the ability to adjust to interruptions in the supply of energy. To that end, he suggests the U.S. make greater use of electricity. Electricity can be produced from a variety of sources. A diverse energy supply will be less affected by the disruption in supply of any one source. He reasons that another feature of electrification is that electricity is "sticky" – meaning the electricity produced in the U.S. is to stay there because it cannot be transported overseas. According to Grove, a key aspect of advancing electrification and energy resilience will be converting the U.S. automotive fleet from gasoline-powered to electric-powered. This, in turn, will require the modernization and expansion of the electrical power grid. As organizations such as The Reform Institute have pointed out, advancements associated with the developing smart grid would facilitate the ability of the grid to absorb vehicles en masse connecting to it to charge their batteries. Present and future Extrapolations from current knowledge to the future offer a choice of energy futures. Predictions parallel the Malthusian catastrophe hypothesis. Numerous are complex models based scenarios as pioneered by Limits to Growth. Modeling approaches offer ways to analyze diverse strategies, and hopefully find a road to rapid and sustainable development of humanity. Short term energy crises are also a concern of energy development. Extrapolations lack plausibility, particularly when they predict a continual increase in oil consumption. Energy production usually requires an energy investment. Drilling for oil or building a wind power plant requires energy. The fossil fuel resources that are left are often increasingly difficult to extract and convert. They may thus require increasingly higher energy investments. If investment is greater than the value of the energy produced by the resource, it is no longer an effective energy source. These resources are no longer an energy source but may be exploited for value as raw materials. New technology may lower the energy investment required to extract and convert the resources, although ultimately basic physics sets limits that cannot be exceeded. Between 1950 and 1984, as the Green Revolution transformed agriculture around the globe, world grain production increased by 250%. The energy for the Green Revolution was provided by fossil fuels in the form of fertilizers (natural gas), pesticides (oil), and hydrocarbon fueled irrigation. The peaking of world hydrocarbon production (peak oil) may lead to significant changes, and require sustainable methods of production. One vision of a sustainable energy future involves all human structures on the earth's surface (i.e., buildings, vehicles and roads) doing artificial photosynthesis (using sunlight to split water as a source of hydrogen and absorbing carbon dioxide to make fertilizer) efficiently than plants. With contemporary space industry's economic activity and the related private spaceflight, with the manufacturing industries, that go into Earth's orbit or beyond, delivering them to those regions will require further energy development. Researchers have contemplated space-based solar power for collecting solar power for use on Earth. Space-based solar power has been in research since the early 1970s. Space-based solar power would require construction of collector structures in space. The advantage over ground-based solar power is higher intensity of light, and no weather to interrupt power collection. Energy technology Energy technology is an interdisciplinary engineering science having to do with the efficient, safe, environmentally friendly, and economical extraction, conversion, transportation, storage, and use of energy, targeted towards yielding high efficiency whilst skirting side effects on humans, nature, and the environment. For people, energy is an overwhelming need, and as a scarce resource, it has been an underlying cause of political conflicts and wars. The gathering and use of energy resources can be harmful to local ecosystems and may have global outcomes. Energy is also the capacity to do work. We can get energy from food. Energy can be of different forms such as kinetic, potential, mechanical, heat, light etc. Energy is required for individuals and the whole society for lighting, heating, cooking, running, industries, operating transportation and so forth. Basically there are two types of energy depending on the source s they are; 1.Renewable Energy Sources 2.Non-Renewable Energy Sources Interdisciplinary fields As an interdisciplinary science Energy technology is linked with many interdisciplinary fields in sundry, overlapping ways. Physics, for thermodynamics and nuclear physics Chemistry for fuel, combustion, air pollution, flue gas, battery technology and fuel cells. Electrical engineering Engineering, often for fluid energy machines such as combustion engines, turbines, pumps and compressors. Geography, for geothermal energy and exploration for resources. Mining, for petrochemical and fossil fuels. Agriculture and forestry, for sources of renewable energy. Meteorology for wind and solar energy. Water and Waterways, for hydropower. Waste management, for environmental impact. Transportation, for energy-saving transportation systems. Environmental studies, for studying the effect of energy use and production on the environment, nature and climate change. (Lighting Technology), for Interior and Exterior Natural as well as Artificial Lighting Design, Installations, and Energy Savings (Energy Cost/Benefit Analysis), for Simple Payback and Life Cycle Costing of Energy Efficiency/Conservation Measures Recommended Electrical engineering Electric power engineering deals with the production and use of electrical energy, which can entail the study of machines such as generators, electric motors and transformers. Infrastructure involves substations and transformer stations, power lines and electrical cable. Load management and power management over networks have meaningful sway on overall energy efficiency. Electric heating is also widely used and researched. Thermodynamics Thermodynamics deals with the fundamental laws of energy conversion and is drawn from theoretical Physics. Thermal and chemical energy Thermal and chemical energy are intertwined with chemistry and environmental studies. Combustion has to do with burners and chemical engines of all kinds, grates and incinerators along with their energy efficiency, pollution and operational safety. Exhaust gas purification technology aims to lessen air pollution through sundry mechanical, thermal and chemical cleaning methods. Emission control technology is a field of process and chemical engineering. Boiler technology deals with the design, construction and operation of steam boilers and turbines (also used in nuclear power generation, see below), drawn from applied mechanics and materials engineering. Energy conversion has to do with internal combustion engines, turbines, pumps, fans and so on, which are used for transportation, mechanical energy and power generation. High thermal and mechanical loads bring about operational safety worries which are dealt with through many branches of applied engineering science. Nuclear energy Nuclear technology deals with nuclear power production from nuclear reactors, along with the processing of nuclear fuel and disposal of radioactive waste, drawing from applied nuclear physics, nuclear chemistry and radiation science. Nuclear power generation has been politically controversial in many countries for several decades but the electrical energy produced through nuclear fission is of worldwide importance. There are high hopes that fusion technologies will one day replace most fission reactors but this is still a research area of nuclear physics. Renewable energy Renewable energy has many branches. Wind power Wind turbines convert wind energy into electricity by connecting a spinning rotor to a generator. Wind turbines draw energy from atmospheric currents and are designed using aerodynamics along with knowledge taken from mechanical and electrical engineering. The wind passes across the aerodynamic rotor blades, creating an area of higher pressure and an area of lower pressure on either side of the blade. The forces of lift and drag are formed due to the difference in air pressure. The lift force is stronger than the drag force; therefore the rotor, which is connected to a generator, spins. The energy is then created due to the change from the aerodynamic force to the rotation of the generator. Being recognized as one of the most efficient renewable energy sources, wind power is becoming more and more relevant and used in the world. Wind power does not use any water in the production of energy making it a good source of energy for areas without much water. Wind energy could also be produced even if the climate changes in line with current predictions, as it relies solely on wind. Geothermal Deep within the  Earth, is an extreme heat producing layer of molten rock called magma. The very high temperatures from the magma heats nearby groundwater. There are various technologies that have been developed in order to benefit from such heat, such as using different types of power plants (dry, flash or binary), heat pumps, or wells. These processes of harnessing the heat incorporate an infrastructure which has in one form or another a turbine which is spun by either the hot water or the steam produced by it. The spinning turbine, being connected to a generator, produces energy. A more recent innovation involves the use of shallow closed-loop systems that pump heat to and from structures by taking advantage of the constant temperature of soil around 10 feet deep. Hydropower Hydropower draws mechanical energy from rivers, ocean waves and tides. Civil engineering is used to study and build dams, tunnels, waterways and manage coastal resources through hydrology and geology. A low speed water turbine spun by flowing water can power an electrical generator to produce electricity. Bioenergy Bioenergy deals with the gathering, processing and use of biomasses grown in biological manufacturing, agriculture and forestry from which power plants can draw burning fuel. Ethanol, methanol (both controversial) or hydrogen for fuel cells can be had from these technologies and used to generate electricity. Enabling technologies Heat pumps and Thermal energy storage are classes of technologies that can enable the utilization of renewable energy sources that would otherwise be inaccessible due to a temperature that is too low for utilization or a time lag between when the energy is available and when it is needed. While enhancing the temperature of available renewable thermal energy, heat pumps have the additional property of leveraging electrical power (or in some cases mechanical or thermal power) by using it to extract additional energy from a low quality source (such as seawater, lake water, the ground, the air, or waste heat from a process). Thermal storage technologies allow heat or cold to be stored for periods of time ranging from hours or overnight to interseasonal, and can involve storage of sensible energy (i.e. by changing the temperature of a medium) or latent energy (i.e. through phase changes of a medium, such between water and slush or ice). Short-term thermal storages can be used for peak-shaving in district heating or electrical distribution systems. Kinds of renewable or alternative energy sources that can be enabled include natural energy (e.g. collected via solar-thermal collectors, or dry cooling towers used to collect winter's cold), waste energy (e.g. from HVAC equipment, industrial processes or power plants), or surplus energy (e.g. as seasonally from hydropower projects or intermittently from wind farms). The Drake Landing Solar Community (Alberta, Canada) is illustrative. borehole thermal energy storage allows the community to get 97% of its year-round heat from solar collectors on the garage roofs, which most of the heat collected in summer. Types of storages for sensible energy include insulated tanks, borehole clusters in substrates ranging from gravel to bedrock, deep aquifers, or shallow lined pits that are insulated on top. Some types of storage are capable of storing heat or cold between opposing seasons (particularly if very large), and some storage applications require inclusion of a heat pump. Latent heat is typically stored in ice tanks or what are called phase-change materials (PCMs).

Descriptive research

Descriptive research is used to describe characteristics of a population or phenomenon being studied. It does not answer questions about how/when/why the characteristics occurred. Rather it addresses the "what" question (what are the characteristics of the population or situation being studied?). The characteristics used to describe the situation or population are usually some kind of categorical scheme also known as descriptive categories. For example, the periodic table categorizes the elements. Scientists use knowledge about the nature of electrons, protons and neutrons to devise this categorical scheme. We now take for granted the periodic table, yet it took descriptive research to devise it. Descriptive research generally precedes explanatory research. For example, over time the periodic table's description of the elements allowed scientists to explain chemical reaction and make sound prediction when elements were combined. Hence, descriptive research cannot describe what caused a situation. Thus, descriptive research cannot be used as the basis of a causal relationship, where one variable affects another. In other words, descriptive research can be said to have a low requirement for internal validity. The description is used for frequencies, averages, and other statistical calculations. Often the best approach, prior to writing descriptive research, is to conduct a survey investigation. Qualitative research often has the aim of description and researchers may follow up with examinations of why the observations exist and what the implications of the findings are. Social science research In addition, the conceptualizing of descriptive research (categorization or taxonomy) precedes the hypotheses of explanatory research. (For a discussion of how the underlying conceptualization of exploratory research, descriptive research and explanatory research fit together, see: Conceptual framework.) Descriptive research can be statistical research. The main objective of this type of research is to describe the data and characteristics of what is being studied. The idea behind this type of research is to study frequencies, averages, and other statistical calculations. Although this research is highly accurate, it does not gather the causes behind a situation. Descriptive research is mainly done when a researcher wants to gain a better understanding of a topic. That is, analysis of the past as opposed to the future. Descriptive research is the exploration of the existing certain phenomena. The details of the facts won't be known. The existing phenomena's facts are not known to the person. Descriptive science Descriptive science is a category of science that involves descriptive research; that is, observing, recording, describing, and classifying phenomena. Descriptive research is sometimes contrasted with hypothesis-driven research, which is focused on testing a particular hypothesis by means of experimentation. David A. Grimaldi and Michael S. Engel suggest that descriptive science in biology is currently undervalued and misunderstood: "Descriptive" in science is a pejorative, almost always preceded by "merely," and typically applied to the array of classical -ologies and -omies: anatomy, archaeology, astronomy, embryology, morphology, paleontology, taxonomy, botany, cartography, stratigraphy, and the various disciplines of zoology, to name a few. [...] First, an organism, object, or substance is not described in a vacuum, but rather in comparison with other organisms, objects, and substances. [...] Second, descriptive science is not necessarily low-tech science, and high tech is not necessarily better. [...] Finally, a theory is only as good as what it explains and the evidence (i.e., descriptions) that supports it. A negative attitude by scientists toward descriptive science is not limited to biological disciplines: Lord Rutherford's notorious quote, "All science is either physics or stamp collecting," displays a clear negative attitude about descriptive science, and it is known that he was dismissive of astronomy, which at the beginning of the 20th century was still gathering largely descriptive data about stars, nebulae, and galaxies, and was only beginning to develop a satisfactory integration of these observations within the framework of physical law, a cornerstone of the philosophy of physics. Descriptive versus design sciences Ilkka Niiniluoto has used the terms "descriptive sciences" and "design sciences" as an updated version of the distinction between basic and applied science. According to Niiniluoto, descriptive sciences are those that seek to describe reality, while design sciences seek useful knowledge for human activities.

Behavior

Behavior (American English) or behaviour (British English) is the range of actions and mannerisms made by individuals, organisms, systems or artificial entities in some environment. These systems can include other systems or organisms as well as the inanimate physical environment. It is the computed response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary. Taking a behavior informatics perspective, a behavior consists of actor, operation, interactions, and their properties. This can be represented as a behavior vector. Models Biology Although disagreement exists as to how to precisely define behavior in a biological context, one common interpretation based on a meta-analysis of scientific literature states that "behavior is the internally coordinated responses (actions or inactions) of whole living organisms (individuals or groups) to internal or external stimuli". A broader definition of behavior, applicable to plants and other organisms, is similar to the concept of phenotypic plasticity. It describes behavior as a response to an event or environment change during the course of the lifetime of an individual, differing from other physiological or biochemical changes that occur more rapidly, and excluding changes that are a result of development (ontogeny). Behaviors can be either innate or learned from the environment. Behaviour can be regarded as any action of an organism that changes its relationship to its environment. Behavior provides outputs from the organism to the environment. Human behavior The endocrine system and the nervous system likely influence human behavior. Complexity in the behavior of an organism may be correlated to the complexity of its nervous system. Generally, organisms with more complex nervous systems have a greater capacity to learn new responses and thus adjust their behavior. Animal behavior Ethology is the scientific and objective study of animal behavior, usually with a focus on behavior under natural conditions, and viewing behavior as an evolutionarily adaptive trait. Behaviorism is a term that also describes the scientific and objective study of animal behavior, usually referring to measured responses to stimuli or trained behavioral responses in a laboratory context, without a particular emphasis on evolutionary adaptivity. Consumer behavior Consumers behavior Consumer behavior involves the processes consumers go through, and reactions they have towards products or services. It has to do with consumption, and the processes consumers go through around purchasing and consuming goods and services. Consumers recognize needs or wants, and go through a process to satisfy these needs. Consumer behavior is the process they go through as customers, which includes types of products purchased, amount spent, frequency of purchases and what influences them to make the purchase decision or not. Circumstances that influence consumer behaviour are varied, with contributions from both internal and external factors. Internal factors include attitudes, needs, motives, preferences and perceptual processes, whilst external factors include marketing activities, social and economic factors, and cultural aspects. Doctor Lars Perner of the University of Southern California claims that there are also physical factors that influence consumer behavior, for example, if a consumer is hungry, then this physical feeling of hunger will influence them so that they go and purchase a sandwich to satisfy the hunger. Consumer decision making Lars Perner presents a model that outlines the decision-making process involved in consumer behaviour. The process initiates with the identification of a problem, wherein the consumer acknowledges an unsatisfied need or desire. Subsequently, the consumer proceeds to seek information, whereas for low-involvement products, the search tends to rely on internal resources, retrieving alternatives from memory. Conversely, for high-involvement products, the search is typically more extensive, involving activities like reviewing reports, reading reviews, or seeking recommendations from friends. The consumer will then evaluate his or her alternatives, comparing price, and quality, doing trade-offs between products, and narrowing down the choice by eliminating the less appealing products until there is one left. After this has been identified, the consumer will purchase the product. Finally, the consumer will evaluate the purchase decision, and the purchased product, bringing in factors such as value for money, quality of goods, and purchase experience. However, this logical process does not always happen this way, people are emotional and irrational creatures. People make decisions with emotion and then justify them with logic according to Robert Cialdini Ph.D. Psychology. How the 4P's influence consumer behavior The Marketing mix (4 P's) are a marketing tool and stand for Price, Promotion, Product, and Placement. Due to the significant impact of business-to-consumer marketing on consumer behavior, the four elements of the marketing mix, known as the 4 P's (product, price, place, and promotion), exert a notable influence on consumer behavior. The price of a good or service is largely determined by the market, as businesses will set their prices to be similar to that of other businesses so as to remain competitive whilst making a profit. When market prices for a product are high, it will cause consumers to purchase less and use purchased goods for longer periods of time, meaning they are purchasing the product less often. Alternatively, when market prices for a product are low, consumers are more likely to purchase more of the product, and more often. The way that promotion influences consumer behavior has changed over time. In the past, large promotional campaigns and heavy advertising would convert into sales for a business, but nowadays businesses can have success on products with little or no advertising. This is due to the Internet and in particular social media. They rely on word of mouth from consumers using social media, and as products trend online, so sales increase as products effectively promote themselves. Thus, promotion by businesses does not necessarily result in consumer behavior trending towards purchasing products. The way that product influences consumer behavior is through consumer willingness to pay, and consumer preferences. This means that even if a company were to have a long history of products in the market, consumers will still pick a cheaper product over the company in question's product if it means they will pay less for something that is very similar. This is due to consumer willingness to pay, or their willingness to part with the money they have earned. The product also influences consumer behavior through customer preferences. For example, take Pepsi vs Coca-Cola, a Pepsi-drinker is less likely to purchase Coca-Cola, even if it is cheaper and more convenient. This is due to the preference of the consumer, and no matter how hard the opposing company tries they will not be able to force the customer to change their mind. Product placement in the modern era has little influence on consumer behavior, due to the availability of goods online. If a customer can purchase a good from the comfort of their home instead of purchasing in-store, then the placement of products is not going to influence their purchase decision. In management Behavior outside of psychology includes Organizational In management, behaviors are associated with desired or undesired focuses. Managers generally note what the desired outcome is, but behavioral patterns can take over. These patterns are the reference to how often the desired behavior actually occurs. Before a behavior actually occurs, antecedents focus on the stimuli that influence the behavior that is about to happen. After the behavior occurs, consequences fall into place. Consequences consist of rewards or punishments. Social behavior Social behavior is behavior among two or more organisms within the same species, and encompasses any behavior in which one member affects the other. This is due to an interaction among those members. Social behavior can be seen as similar to an exchange of goods, with the expectation that when one gives, one will receive the same. This behavior can be affected by both the qualities of the individual and the environmental (situational) factors. Therefore, social behavior arises as a result of an interaction between the two—the organism and its environment. This means that, in regards to humans, social behavior can be determined by both the individual characteristics of the person, and the situation they are in. Behavior informatics Behavior informatics also called behavior computing, explores behavior intelligence and behavior insights from the informatics and computing perspectives. Different from applied behavior analysis from the psychological perspective, BI builds computational theories, systems and tools to qualitatively and quantitatively model, represent, analyze, and manage behaviors of individuals, groups and/or organizations. Health Health behavior refers to a person's beliefs and actions regarding their health and well-being. Health behaviors are direct factors in maintaining a healthy lifestyle. Health behaviors are influenced by the social, cultural, and physical environments in which we live. They are shaped by individual choices and external constraints. Positive behaviors help promote health and prevent disease, while the opposite is true for risk behaviors. Health behaviors are early indicators of population health. Because of the time lag that often occurs between certain behaviors and the development of disease, these indicators may foreshadow the future burdens and benefits of health-risk and health-promoting behaviors. Correlates A variety of studies have examined the relationship between health behaviors and health outcomes (e.g., Blaxter 1990) and have demonstrated their role in both morbidity and mortality. These studies have identified seven features of lifestyle which were associated with lower morbidity and higher subsequent long-term survival (Belloc and Breslow 1972): Avoiding snacks Eating breakfast regularly Exercising regularly Maintaining a desirable body weight Moderate alcohol intake Not smoking Sleeping 7–8hrs per night Health behaviors impact upon individuals' quality of life, by delaying the onset of chronic disease and extending active lifespan. Smoking, alcohol consumption, diet, gaps in primary care services and low screening uptake are all significant determinants of poor health, and changing such behaviors should lead to improved health. For example, in US, Healthy People 2000, United States Department of Health and Human Services, lists increased physical activity, changes in nutrition and reductions in tobacco, alcohol and drug use as important for health promotion and disease prevention. Treatment approach Any interventions done are matched with the needs of each individual in an ethical and respected manner. Health belief model encourages increasing individuals' perceived susceptibility to negative health outcomes and making individuals aware of the severity of such negative health behavior outcomes. E.g. through health promotion messages. In addition, the health belief model suggests the need to focus on the benefits of health behaviors and the fact that barriers to action are easily overcome. The theory of planned behavior suggests using persuasive messages for tackling behavioral beliefs to increase the readiness to perform a behavior, called intentions. The theory of planned behavior advocates the need to tackle normative beliefs and control beliefs in any attempt to change behavior. Challenging the normative beliefs is not enough but to follow through the intention with self-efficacy from individual's mastery in problem solving and task completion is important to bring about a positive change. Self efficacy is often cemented through standard persuasive techniques.
