Dear…,
I’m from No. 1 Middle School. I like our city, but the environment around here is getting worse and worse.
First, there is white pollution everywhere in the city. People use too many disposable things, such as plastic cups, bottles, bags and lunch boxes. People throw them away after only using them once.
I think that people should try to use their own cups, lunch boxes and chopsticks instead of disposable things. Second, there has been haze in the city in recent years. That’s because there are more and more cars on the road and they give off too much waste gas. People should use public transportation more. It’s a good idea to take buses and use shared bikes. I think the government should encourage more people to use new energy vehicles.
I hope the environment in your city gets better and better.
Yours sincerely,
…
