Should government spend money on highways or public transportation? Should governments spend more money on improving roads and highways or on improving public transportation? It is a hard decision to governments when they have only limited money to allocate To my opinion, the better way is to improve public transportation for it carries more advantages than the other one The first and foremost, improving public transportation provides more convenience in transportation and, in turn, facilities cutting the number of private transportation vehicles, so as to reduce the air pollution It is well know that the gas emitted from the cars is the major reason to cause acid rain and green-house effect, which threat our normal life more and more Protecting the environment is one important role for governments The other advantage of improving public transportation is to release the traffic congestion, which has been a serious problem in our daily life, especially to people who live in big cities We spend too more time on the way to work and go back home The decrease of private vehicles is an effective way to solve this problem On the other hand, improving roads and highway is also helpful to solve the problem However, if the public transportation is not improved, the dramatically increasing in private cars will comprise the advantage of more roads and highways The last but not the least, people prefer public transportation to private cars Using public transportation make people relax and enjoy the trip The reason why people use private vehicles is that, sometime, the public transportation is not contentious enough comparing to the private vehicles If the public transportation is improved, more people will shift to public transportation accordingly In short, improving public transportation is the better way to effectively solve the problems of pollution and traffic jam than improving roads and highways Governments should spend more money on public transportation instead of roads and highways
