This video, entitled Permaculture: A Quiet Revolution, is a great one for those of us who already love permaculture & for those of us who don't yet know what it is. For the latter, permaculture is a design theory that seeks to create small-scale regenerative systems of agriculture & culture. It is one of the more practical & practiced frameworks for sustainability that exists. This video gives a decent notion of its current scope around the world.
