Another possible version:

　　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.
