The school is our home, we should protect the environment in the small yard.
We saw the earth h**e pick up rubbish should put the rubbish into the trash can, we cant eat your own trash on the ground after the funeral, if someone do so should be to remind him, let him pick up garbage into the garbage can.
We need to protect the objects on campus, such as: we should protect the playground on the playground every camphor tree, cant use a knife to get the camphor tree, because the camphor tree is a rare tree. One can sell one or two in case of a tree, so we should protect the camphor tree.
We should also protect the flowerbeds in the flowerbeds, the flowers in the flowerbeds, and we cant pick it because it will spoil the environment.
