有关校园环境问题的英语作文

Recently,I find that there are some problems in our school.For example,more and more students don't care about the enviroment so they throw plastic bags .It is convenience for them to put rubbish in the garbage bin.But they don't do as they should do.What's worse,they always trample on the lawn loosely and carelessly.The appearance of things make me upset.As an excellent student,we should love our school rather than do something to damage it's enviorment.We can plant some trees as well as keep our school cleaning.Don't step into the lawn so that keep the grass green.We are looking forward to see our school become more and more beautiful,are't we?
