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.
