On campus, there are constantly paper heads appearing in playgrounds, flower beds and corridors. A gust of wind blew and the paper flew like snowflakes. I really don't understand, why don't those paper-headed "owners" go a few more steps and throw the garbage into the dustbin instead of throwing it casually? If you really don't have a trash can next to you, take it in your hand first and then throw it into the trash can after you see it. In our school, hygiene has been tight, the classroom is clean, but the outside of the classroom is dirty. Because there is a teacher in the classroom, the teacher can't see it outside. Some children are spoiled by their parents at home, and they may even litter at home! The habit of littering is bad. We can't make friends with it. We should form the good habit of not littering. How can we stop people from throwing paper about? I think we should let everyone know the disadvantages of littering and that paper is made of bark and rags. In order to make a lot of paper, we must cut down several trees. Didn't we all say we should protect trees? Paper can be recycled. If you throw paper into the dustbin and let it be recycled, it will save several trees!
What's the matter, Brother Pig?
