I think it is a good idea to construct green school campus. Here are my suggestions.

Firstly, we should beautify our school with paintings and handwritings of famous artists from home and abroad in proper positions. We can also improve what we have done in recent years. Secondly, we should perfect the green belt in our school by planting more trees and grass. Thirdly, I think recycling text books is also a good way to save the resources. And there are still many things we can do. In a word, we can make our school more beautiful in practical ways and this can form unique school culture for teachers and students.
