Why should we keep our school green and clean

Explanation: When going to a school you are there for a academic based learning but what about the enivorment you work in the reason we should keep our schools clean is because it is harder to learn in a messy disfunctional enviorment for example if we had trash littered across the room and books shoved everywhere how would we be able to find anything and the reason we keep our schools green is because when we go to school we have hot lunchs cold lunchs snacks we bring and all the trash to go with it so the reason schools are green is because it is better for the enviorment also we learn from the eviorment around us so if we see our school recycling it might compel us to do the same.
