The environment is more and more important for us especially the environment of our school. These days the school's environment is worse and worse. You can see some students throw their trash everywhere. For our students we stay at school for almost 7-8 hours everyday. Why some of the students don't concern about the environment around them? First I suggest them to learn more about the knowledge of the environment. Second I hope they can understand the feelings of other students. If everybody can think more about others, the world can be more clear. So let's do it from ourselves.
