Dear Sir/ Madam,
Environmental problems are becoming more and more serious in our hometown.
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. And Bayi Road is very crowded and noisy because of the heavy traffic. People also put waste into the river and Wuxian Mountain . So whenever we climb the moutain, we can find rubbish everywhere.
Now more and more people have realized these problems. First, I think that governments should develop laws to stop people from driving cars every day. Besides, I suggest everyone in this city should help to clean up the river and the moutain. Every one is supposed 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.
保护环境从我做起!
If everyone makes a contribution to protecting the environment, our earth will become more and more beautiful.
Thank you!
