English: Photo of Will Allen of Growing Power taken in greenhouse #7. It is a community gardening coop, where he teaches inner city residents to grow their own food and to use coop farms. In the last year and a half, Allen has added aquaculture to his greenhouses, in a system the that WATER Institute helped to hone: the plants purify the water and where the fish are raised.
