How to write littering?

The slogan about "littering" is introduced in detail as follows:

1. Refuse to use non-degradable foamed plastic lunch boxes, plastic bowls and plastic cups, and use tableware provided by the canteen or bring your own tableware for dining. Protect the green campus, reject white pollution, don't use plastic bags if you can, use them less if you can, and reuse them if you can. Consciously throw discarded plastic bags and other items into the dustbin, and do not throw them away at will.

2. Everyone should be an environmental angel and a green propagandist. We should make use of our own advantages, widely publicize the harm of plastic products, influence people around us with practical actions, and constantly improve the ecological environment around us, so that everyone cares about hygiene and loves environmental protection. Let's join hands, start from me, start from now, reject "white pollution" and build a green campus together. We believe that as long as everyone is involved, "white pollution" will be farther and farther away from us, and the campus of life will become more and more beautiful.

3. Littering is a bad behavior. There is so much garbage in the classroom that you should take the initiative to pick it up when you see it, so that others can see it. In order to have a good mood. The school is a garden-like campus, so littering is an uncivilized habit. First of all, you can see the garbage picked up actively, or you can prepare a garbage bag. When the garbage in the garbage bag is full, you can throw it directly into the garbage room. If you see someone littering, you can punish him.
