It's our duty to keep the city clean and tidy. So we should collect waste paper and empty bottels for recycling. And we should plant trees and flowers. We shouldn't throw waste about or spit in public. If everyone tries his best , I am sure the city will get more and more beautiful

The important to protect environment
"敏猛御信No water, no creatures"桥拆桥 It's ture that the human being will run the end if there is no water in the world. Man can live for about 7days without any food, but 3 days without water. But I know that environmental pollution in our country is becoming more and more serious. In the country, we can see women washing clothes in the river. Litter is floating on the river. Waste water produced by a chemical factory is being discharged into the river. We do not see any fish in the river. The river is not so clear as before. Water quality is very bad. I am worried about it because water is important to all living things. Man can not live without water. I hope people pay more attention to this problem, especially the government. Try to control the pollution of water as early as possible. At last I would like to say, "To protect environment is to protect life."
