My fellow students，
Our environment is becoming worse and worse．As students，what can we do to protect the environment？

To reduce white pollution we should use fewer plastic bags when going shopping．Use cloth bags instead．We should try to reuse old textbooks，so people needn't cut down more trees to make paper．In order to save energy we should use the lift less and take the stairs instead．We should also save water and electricity．And we should plant more trees so that the air will be fresher．Besides，it would be better if we walked or rode a bike to school．

In fact，even the simplest everyday activities can make a difference to the environment．I believe that by working together we can make the world a better place to live in．
