The use of auto-mobile has caused a number of problems nowadays and many provinces of China have carried out some policies to limit private cars. In my opinion, this kind of policies are very essential for us.
Firstly, the gas emission caused by cars can reduce air quality and lead to greenhouse effect. With more and more private cars come into use, it has got worse. Secondly, the consumption of fuel can drive the oil price higher, which will affect the price of commodities. Thirdly, the growing number of private cars also can cause traffic jam, which can bring about inconvenience to our life. What is more, instead of walking, people may choose to rely on their cars, which is not good for their fitness.
In conclusion, I believe the limitation for private cars is very necessary. It can improve our environment, reduce traffic problems, and let us develop a healthy lifestyle.
