CCCBAII.One possible version:Fresh air is very important to human beings and animals. However, with the development of industry, air pollution has become a serious problem. Burning oil and chemical factories have polluted the air. And the more cars there are in the street, the more serious the air pollution is. The air pollution does great harm to human beings. It causes breathing problems and even causes cancer. Whats worse, the air pollution makes the roads more dangerous. What can we do to prevent the air pollution? First, the government should take measures to stop factories from pouring the waste gas directly. Second, people should plant more trees and spread the messages about protecting the air. We should do everything we can to protect the air.
