Permaculture

I was looking at some web pages linked to That Roundhouse when I came across the concept of "permaculture." Apparently, it's the idea of "permanent agriculture." It is a reaction against industrial agriculture and the loss of the notion of "community." Permaculture attempts to replicate natural plant systems, though some use these simply as a starting point. I think it is a good idea, and am interested in learning more. It is much less intensive (so its proponents claim) than "traditional" agriculture. I don't know if I agree but I'd like to try it to find out.
