Will increasing the price of petrol be a best answer to solve the traffic and pollution problems? Nowadays, there are more and more traffic congestion and air pollution over the world, in particular, in big cities. People are paying more attention to those growing problems and some think raising the price of petrol is the best way to solve them. But I hold a negative attitude towards it. It is true that less people would buy cars if the price of petrol increased, whereas is it a long-term and effective measure to control the increasing number of cars? My answer is no. The most essential factor of growing traffic and pollution problems is a high level of people’s demands for cars. It is widely acknowledged that in modern society people from all walks of life rely heavily on private cars. Wherever they go and whatever they do, cars could always be reliable and helpful partners of them. Thus, even if petrol price was on an upward trend, people would buy them sooner or later as long as they feel cars are a must. However, that doesnot mean it is inevitable to see traffic condition getting worse as well as air pollution. We indeed can do something to help improve those troublesome issues. Responsibilities should be shared between governments, business, civil society and every individuals. Governments are supposed to promote infrastructure construction, for instance, to broaden the road. Besides, Those who break traffic rules should be punished strictly. Thus less accidents would happen. Also, innovation is encouraged in car-making companies. Cars in the future are expected to be more eco-friendly, which will undoubtedly improve our poor air condition in a sustainable way. So to finalize, I think the future is not like a fate that you have to just go as business as usual goes. We need to have the courage to actually change the route. And there is no single way to solve problems. All ways should work together to fight for our common lovely living environment.
