　　The environment is becoming worse and worse. There are many kinds of pollution I worry about. The most serious two are water pollution and air pollution, because people can"t live healthily with dirty water and polluted air, nor can animals. More and more diseases are caused by polluted air.

　　I think factories should not pour dirty water into the river directly or produce more waste gas. We"d better go on foot or by like instead of by car, because more cars mean more waste gas. We should make our world more and more beautiful.

　　The first fact I worry about is noise pollution. People can"t sleep well if there is too much noise. That"s why so many people prefer to live in the countryside rather than live in the noisy city. I suggest all the factories and cars shouldn"t make terrible noises. If they make terrible noise that isn"t allowed, they will be fined, and we can also produce the cars which can"t make terrible noise.

　　The other pollution is rubbish pollution. If everyone makes so much rubbish, one day we may live in a world filled with rubbish. Some people throw the waste paper about. I suggest rubbish should be put into different kinds of dustbins or paper bags.
