As we know, the nice environment is good for our life and health. However, there a
3、re some kinds of pollution problems in our life, like air pollution,noise pollution, water pollution and waste pollution. Now I want to talk about the air pollution.The air is badly polluted. Here are some reasons. First, the factories that bum coal pollute the air with a lot of black smoke. Second,
4、 more and more people take cars to school or work. Third, some people smoke.There are some methods to solve the problem. First of all, we should ask the factories to stop giving out black smoke into air. Next, wed better ride bikes or walk instead of driving to school. The advantages of bike riding
5、or walking are that its good for health and it doesnt cost anything. If its far, I suggest we could take the bus. Besides, I think smokers shouldnt smoke in public. Whats more, its a good idea to plant more trees and flowers. Planting trees not only makes air cleaner, but also makes our environment more beautiful. Finally, we need to recycle books and paper and stop using paper napkins. That can help us cut down fewer and fewer trees.I think everyone should play a part in solving the air pollution. Im sure that our actions can make a difference and lead to a better future.
