Geoff Lawton is permaculture specialist, designer and teacher. He is very generous to offer his free videos on his website, from building a house for $500.00 to creating an oasis in the desert without a lot of rainfall and in extreme temperatures.
He has created his own farm to be self sufficient and wants to teach all of us to do the same. He even has a video on how not to buy grain for chickens by feeding them compost !
