TreeHugger posted an amazing photo gallery of green roofs all over the world from the Green Roofs For Healthy Australian Cities web site: "TreeHugger loves green roofs--they can be beautiful architectural elements or 'a rooftop food production system that meshes the technologies of aquaponics, vermiculture, rooftop water harvesting, and solar-powered air moisture harvesting.'"
