Because Our cities has many factories that burn coal. Every year these factories pour a large amount of black smoke into air. Besides there are more cars in cities now. 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，we'd better ride bikes or walk instead of driving to school. The advantages of bike riding or walking are that it's good for health and it doesn't cost anything. What's more，it's 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. I'm sure that our actions can make a difference and lead to a better future.,
