One possible version
Dear 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.
Step 4 : Practicing and promoting learning.存在有哪些环境问题，是谁造成的这些问题，然后提出解决这些环境问题的方法和措施，可以结合3a中列举的问题和前面学过的解决办法来完成这封信。
