怎样保护我们的环境(how to protect our environment)

　　our environment is getting worse and worse now. people throw their garbage here and there. factories make more and more dirty water that has polluted the rivers and lakes. what should we do?

　　we must find ways to stop pollution. waste water must be cleaned before it is poured into the river. people shouldn't throw away rubbish here and there. we should pick up the garbage around us. we'd better plant more trees.

　　i'm sure if we take care of our environment, our world will be more beautiful!
