tokens: Should governments spend more money on improving roads and highways Nowadays transportation has attracted much social concern . Whether governments should invest more money in traffic infrastructure or focus more on developing public transportation has erupted endless controversy . It does not seem unreasonable to suggest that governments spend more money on buses, trains, and subways investment . Such public vehicles are used to serve a large number of people in society therefore they help alleviate traffic congestion and decrease the amount of carbon released into the air . Both these two things are important . First and foremost, carbon emission cut is significantly essential for protecting the atmosphere . The fact is that the more cars and motorbikes are on roads, the more seriously the ozone layer is damaged . If governments use more money to improve roads, there is a strong likelihood that more people drive their private cars work . This is sure to lead to more carbon emitted into the atmosphere, which can cause skin cancer and destroy the natural environment . Whereas, if there are more good buses, trains, or subways, people are inclined to use less private vehicles, which decreases the amount of carbon released . Obviously, the policy that concentrates money on developing public transportation brings an advantageous impact on earth . In addition, the policy would play a pivotal part in relieving traffic jam . It is quiet clear that traffic congestion is a serious problem in many big cities . The main reason for this issue is that there are a great number of vehicles flowing on roads . In order to tackle the problem, governments have to turn people' attention on public vehicles to reduce cars and motorbikes . There is the possibility that improving roads and highways does not seem to reach the major cause of traffic congestion . In conclusion, I would concede that high-quality roads and highways make it easier to move around . Nevertheless, public transportation systems even have more important advantages . They not only ease traffic jam but also protect the atmosphere . That is why many governments around the world invest more money on developing public transportation facilities .
