Dear Rinn,
My city is facing many environmental problems, but I think the biggest one is air pollution.
The air is pollute with smoke from vehicles going on the road. I often feel uncomfortable and breathless when I go out and I have to wear a mask. Another reason is because people often burn waste along the road. The toxic smoke makes the air become dirty.
Some people in my city try to persuade people to use public transport so that there are less vehicles on the street. Besides, we talk to people about the environment so no one will burn waste on the road. But the air is still polluted now. I hope it will be clean someday.
It's my city's problem. Write back to me as soon as possible.
Best ,
