Mr. Mayor,
Now our environment is becoming worse and worse. With the development of the society, there are too many cars on the streets in our town. Cars have made the air unhealthy for people to breathe. Black smoke and harmful gas are given off by factories. Factories also put waste into the river. And wherever we go, we can find rubbish. It is unpleasant to look at these and it makes the environment very unhealthy.
Model passage
Now more and more people have realized these problems. I think that governments should close down the factories and develop laws to stop people from driving cars every day. I suggest everyone in this town should help to clean up the river and the streets. It’s a good way to call on everyone in the town to throw rubbish in the bins.
I hope the problems will be solved in the near future and our home will become better and better.
Best wishes,
Tom
