Are cars doing more harm than good？ Since China has such a large population, the popularization of private cars will bring out a lot of social problems. Some people are of the view that cars are doing more harm than good. Such as the traffic jam and the damage to the environment... Other people take an opposite side that cars are doing more good. With the popularization of cars, the suburbs will become more developed, and the downtown areas will be less crowded. Using the cars is very convenient. As far as I am concerned, the former opinion is preferable in many senses. Several years ago, there were few cars so that people have no choice but to take a bus to go to work. But now, an increasingly number of people would like to take a bus to go to work because of the heavy traffic. With the increasing of cars, there are more and more traffic accidents in the world, especially in China. The most important thing is that the emission from the car contains a large volume of harmful gases. Some of the gases, such as the carbon monoxide and carbon dioxide, not only be harm to the health of people but pollute the atmosphere.
