So, I'm leading a group meeting tomorrow on Permaculture, and I needed to catch up on what it is and why it is important. This is for the up and coming Evolver Boston group, that I'm helping to get rolling in the area.
One of the co-founders of it is Bill Mollison, I did a youtube search for him and found tons of stuff.
Some of the other videos I watched complemented the wikipedia article nicely.

Hope you find permaculture as interesting as I do. These are forest garden systems that you can leave alone for multiple months in a row… fantastic stuff.
