One possible version:

As a middle school student , we should take an active part in creating a society that saves.

On the one hand , the natural resources are limited . We don’t have enough water , oil or forest in many places . On the other hand , people keep cutting down more trees and letting out more carbon dioxide . At the same time , everyone can see that the environment is getting worse , People suffer from more typhoons and tornados nowadays . What’s worse , air and water pollution is becoming more and more serious.

In my opinion , we students should do something to stop wasting . We can save food , water , paper ,electricity , etc . in our daily life . Meanwhile , we should take buses instead of cars ,refuse to use chopsticks which are only used once and don’t use plastic bags.
