Now more and more people get to know it's important to protect our living environment.As a student，it's my duty to do something for the earth. From now on, I'll go to school by bike or on foot instead of in a car. I'll use fewer plastic bags to reduce white pollution. In order to save energy I'll plant more trees so that the air will be fresher. I'll take less lift and reuse water. At last l will use second-hand books,so we don't need to cut down more trees.If everyone takes action, our enivronment will be better and better. Our world will be more beautiful.
