Write a proposal on the phenomenon that 166 class classroom is messy and littering is repeatedly prohibited.

Beautiful learning environment is what our primary school students need most, but the recent behavior of students who don't care about the environment has destroyed our beautiful learning environment.

If you spit everywhere in the classroom, will you throw one or two paper balls on the ground, but don't you pick them up and throw them into the trash can after seeing them? This is the appearance that students don't care about classroom hygiene. Teachers have repeatedly told students not to litter and spit everywhere, but some students just don't think so, and littering is "arbitrary". The reason for this series of consequences is that students' awareness of environmental protection is too weak and they simply don't know the serious consequences caused by environmental pollution.

In view of these problems, I would like to make the following suggestions to you:

1. Carry out an activity to protect the environment, and let students participate in it to better understand how to protect the classroom environment.

2. Put one or two more trash cans in the classroom, put them in the hands of students, and have a good place in their mouths.

Once a week, we should carry out the slogan of protecting the environment, asking students to protect the surrounding environment from me and stop people around them from polluting the environment in time to remind them to protect the environment.

Encouraging students to save more paper is a good way to protect the environment.

I believe that with your call and our efforts, our awareness of environmental protection is gradually improved, and the hygiene of the classroom is getting better and better. Protecting the environment is imminent, and we have certain responsibilities. Let's protect our learning environment together!
