We don't have to suppose we need oil, or governments, or anything.

The agriculture taught at colleges between 1930 and 1980 has caused more damage on the face of the Earth than any other factor.

There is one, and only one solution, and we have almost no time to try it. We must turn all our resources to repairing the natural world, and train all our young people to help. They want to; we need to give them this last chance to create forests, soils, clean waters, clean energies, secure communities, stable regions, and to know how to do it from hands-on experience.

We're only truly secure when we can look out our kitchen window and see our food growing and our friends working nearby.

Anything that's any good is self-perpetuating.

I'd come into town from the bush - after 28 years of field work in natural systems - and become an academic. So I turned my attention to humans, much as I had to possums in the forests.

I believe humanity is a pretty interesting lot, and they're all really busy doing and thinking interesting things.
