tokens: Cheap air travel should be encouraged? In recent years, many airlines offer to their customers more and more number of cheap flights . People have various different views about cheap air travel . Although there are good arguments in favour of this trend should be encouraged, I personally think that cheap flight can make many serious problem . It is undeniable that cheap air fares have broadened travel possibilities for many people, particularly for the lower income group . These days, millions of people can travel around the world for work or pleasure . They can develop their careers, broad their knowledge, and interact with many other people from varied cultural backgrounds . Moreover, travels also help to promote the tourist industry development, boost the economy and job markets of many countries . On the other hand, growing of cheap flights really have negative impact on environment . Apparently, more flights could mean bigger and busier airport that may be grown the air pollution for people who live and work close to it . However, the biggest concern is the effect on global warming . Burning plane fuel can releases carbon dioxide into environment that cause the Earth to heat up . In fact, while many efforts are being made to reduce CO2 emissions from cars and factories, nothing is being done to reins the airlines . In conclusion, I would argue that the drawbacks of cheap air fares outweigh the benefits . However, it does not mean that air travel should be more expensive . Instead, people should be aware of their responsibility to reduce the emissions caused by their lifestyle choices .
