“You don’t have a snail problem, you have a duck deficiency.”

Anything that’s left that’s remotely like wilderness should be left strictly alone. We have no business there any more. It’s not going to save you to go in and cut the last old-stand forests.

Permaculture is an integrated, evolving system of perennial and self-perpetuating plants and animal species useful to man.

I think it’s pointless asking questions like “Will humanity survive?” It’s purely up to people – if they want to, they can, if they don’t want to, they won’t.

You can’t get the mud huts right if you haven’t got things right where you are. You’ve got to get things right, working for you, and then go and say what that is.

When you go into MMA you really can’t do it half-assed. If you do it half-assed, then you’re going to get annihilated.

I can easily teach people to be gardeners, and from them, once they know how to garden, you’ll get a philosopher.

We can predict only those things we set up to be predictable, not what we encounter in the real world of living and reactive processes.

Our forest ancestors may well have followed some such sequences for orchard evolution, assisted by indigenous birds and mammals.

You can’t cooperate by knocking something about or bossing it or forcing it to do things.

If you get someone who looks after himself and those around him, that’s a deep ecologist. He can talk philosophy that I understand.

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

I could never teach people to be philosophers – and if I did, you could never make a gardener out of them.

Pollution is an unused resource.

We are surrounded by insurmountable opportunities

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.

The tragic reality is that very few sustainable systems are designed or applied by those who hold power, and the reason for this is obvious and simple: to let people arrange their own food, energy and shelter is to lose economic and political control over them.

I’m a vegetarian, I’m not strict. I eat fish. And duck, but they’re nearly fish aren’t they.
