Along with the economic growth, private cars have penetrated into a wealth
of citizens’ lives because of its convenience features. Undoubtedly, the
widespread use of cars promotes the social productivity and enhances the
economic development. But we are supposed to weigh strengths and weaknesses of
the popularity of cars. With the growing prevalence of vehicles, a host of
problems have emerged.
In the first place , car emissions are having an immeasurable effect on the
world’s climate. Solid scientific evidence can confirm this harm. Second,
because the car depends so heavily on fossil fuels, it is a major source of
carbon dioxide that causes global warming. Additionally, soaring ownership of
cars puts tremendous pressure on the limited capacity of current transport
system. There is a heavy urban traffic flow with frequent traffic jam. These
harmful side effects of autos burden our society with unacceptable costs to
human health, the environment, and our economy.
So we must reverse this rising trend and promote the mass transportation.
Our heavy reliance on private cars must be
reduced.
