Low-carbon Life 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.
