Nowadays, an increasing number of people have become car owners. Yet there is no consensus on the development of private cars. Some people hold the positive view. They say that the car is the result of modern science and technology and everyone is entitled to enjoy it. They also argue that the development of private cars will vigorously stimulate the development of other industries and the whole national economy.

　　Others, however, hold the negative view. They point out that the increasing number of cars have led to a series of problems. First, they result in air pollution, which seriously damage people’s health. Secondly, too many cars on the road easily lead to traffic jams, which actually slow down the pace of life and work.

　　Weighing the pros and cons of these arguments, I am inclined to agree with the latter point of view. The government should put a ban on the development of private cars and exert more efforts to develop public transportation, such as buses and subways. In this way, we can both enjoy efficiency and a clean environment.
