Private Cars in China

Private Cars in China

In China, a lot of people own private cars.
There is no doubt that private cars make us travel faster and farther, but they have caused some problems. First, too many private cars make the road crowded and cause traffic jams. Second, they pollute the air. Third, they cause a lot of traffic accidents.
How can we solve these problems? I think we should go to work by bus instead of driving private cars. Only in this way, can we protect our living environment.
