Foliage Green

How can I convince my school to install a green roof?
Green roofs are a really awesome concept: the roof of a building is converted into a foliage-covered wonderland! Basically, the roof is covered in grasses, flowers, mosses, whatever works for the area.
ANYWAYS, I plan on convincing my school to install one, but it is a little expensive, and it’s not a “rich” school, per se. How do I get them to agree that the environmental benefits are worth it?
They might well agree with your idea if you ask about it. There are environmental and economic benefits to having a green roof (see link below for ideas). But it will probably come down to money.
There might well be grants or funding available for doing something like that in your state/country (there are in the UK!). See if you can find out about this.
In the meantime, why not start small – get people into gardening – see if the younger kids can get a vegetable patch, for example and see if you and some of your mates can help them out with growing stuff. Do you do recycling? Does the school use recycled paper for printing handouts etc.? Start small and get people involved and enthusiastic. Tell the local papers what you’re doing! Your shcool will see that it benefits everyone to be green and start getting a good reputation – that it might make better still by getting a green roof (perhaps on a new building)!
