One possible versionDear Sir/ Madam,
Environmental problems are becoming more and more serious all over the world.
With the development of the society, there are too many cars on the streets in our city. Cars have made the air unhealthy for people to breathe. Black smoke and poisonous gas are given off by factories. Factories also put waste into the river. And wherever we go, we can find rubbish. 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. We should call on everyone in the town to throw rubbish in the dustbins.
I hope the problem will be solved in the near future and our home will become better and better. Self Check1. Write different forms of the words. Then add more to each group.v.— n.pollute ---
