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 【少用塑料袋】to reduce white pollution【减少白色污染】. 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【循环用水】. At last l will use second-hand books【使用二手书】,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.
