How to protect our environment has become one of the biggest problems in the world. We do everything can do a real difference to our environment.
We need to pick up litter around us. You'd better join a programme to protect our environment. You mustn't cut down too many trees. We can protect factories from polluting the rivers.
We can do our best to keep the air clear! I hope everyone do these!
