I gave one permaculture course in Botswana, and now my students are out in the bloody desert in Namibia teaching Bushmen - whose language nobody can speak - to be very good permaculture people.
Bill MollisonThere are only four things in all cleaners - whether it's shampoo, laundry detergent, whatever.You buy them in bulk and you mix them up properly, and they all work. It doesn't matter if they call the stuff ecologically friendly or have dolphins diving around on the label - it still has these damn four things in it. Anything else is just unnecessary additions to make it smell good or color it blue when it goes down the toilet.
Bill MollisonPermaculture is an integrated, evolving system of perennial and self-perpetuating plants and animal species useful to man.
