If you get someone who looks after himself and those around him, that's a deep ecologist. He can talk philosophy that I understand. People like that don't poison things, they don't ruin things, they don't lose soils, they don't build things they can't sustain.

People do things which I find quite amazing - things I would never have done and can't understand very well.

"Should we tamper with nature?" is no longer a question - we've tampered with nature on the whole face of the Earth.

Use all the skills you have in relation to others - and that way we can do anything.

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.
