Class:
hello!The protection of the environment is getting more and more attention. However, I find that there are many uncivilized phenomena on our campus. I saw people spitting on campus, people throwing rubbish, and people destroying trees and breaking flowers. How dangerous these uncivilized behaviors are to the world! If everyone spit and throw rubbish, how dirty the road is! If there were no trees and flowers, would our earth still be able to live? So, protecting the environment, we should start from every little thing around us.
Lets go, class! Be a civilized student, protect the environment and create our beautiful homeland together.
