保卫地球
As time goes by, man is making the earth sick. People cut down too many trees and leave rubbish everywhere. Factories let out their waste without doing anying to it . This has cause some serious probls. Such as the land is sandy, the river is dirty, the air is less clean, even the tperature of the earth is rising. What should we do to save the earth ? My suggestion is that we should plant more trees, put rubbish into dusbins and stop factories pouring waste directly into the air or rivers. In all, we have only one earth, we should do our best to protect it, or we will regret.
