I probably lead a very spoiled life, because I travel from people interested in permaculture to people interested in permaculture. Some of them are tribal, and some of them are urban, and so on.

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.

The important thing is not to do any agriculture whatsoever, and particularly to make the modern agricultural sciences a forbidden area - they're worse than witchcraft, really.

Instead of physicists teaching physics, physicists should go home and see what physics applies to their home.

You can't live like a Bushman or an Aborigine anymore, so they've got to rethink the whole basis of how they're going to live. Permaculture helps you do that easily.

What is proposed herein is that we have no right, nor any ethical justification, for clearing land or using wilderness while we tread over lawns, create erosion, and use land inefficiently. Our responsibility is to put our house in order. Should we do so, there will never be any need to destroy wilderness.

Permaculture is something with a million heads. It's a way of thinking which is already loose, and you can't put a way of thinking back in the box.
