It’s our duty to protect the environment. I think we should keep our schools and cities clean and tidy. Here are some of my views:Don’t spit in public and throw rubbish everywhere .And we should plant trees and flowers around the city. It’s important to recycle paper and water. Don’t forget to turn off the lights when we leave the room. We had better walk or ride bikes to school to keep our streets clean. We must do our best to make our world more and more beautiful in the future. Do you think so ?
