Dear Sir/Madam,
　　I'm glad to tell you something about the environment in our city. I have lived in this city since I was born and I love this city very much.
　　I think that there are beautiful areas in this city, but the air pollution is getting worse and worse now. In our city, the river used to be so clean. But now it is polluted badly. We can not catch fish any more.The rubbish bins are at the bottom of our apartment blocks. There is rubbish coming out of the bins. It makes the environment very terrible.
　　The reason is that the rubbish collectors do not come often enough to collect the rubbish. The people living here may also be throwing away too much rubbish.
　　We can try to ask people to protect our environment. I suggest that rubbish should be taken away more often.
　　I believe that a better environment can be created in this city and we should all work together to achieve it.
　　Best wishes,
Yours faithfully
