A farm on top of a supermarket: BBC recently covered a not-for-profit project to turn the roof of a supermarket in London into an organic vegetable garden. Compost heaps and worms on the roof turn produce waste from the store into soil for the garden. There are plans to harvest rainwater as well. The fruits and vegetables grown in the garden will be sold in the grocery store; proceeds will support the garden. The project is staffed by local volunteers, for whom the rooftop garden serves as a haven from the London bustle.
