If you understand it from an ecological or sustainability perspective, agriculture is the primary way we meet most of our needs, and it's the greatest form of human intervention on our environment. It has intimately shaped our culture as powerfully as industrial modernity, but for ten thousand years rather than two hundred.

It is not the project but the living process that will be the measure of our actions.

I thought if something was a good idea, we should be able to apply it to ourselves as guinea pigs and do something with it, rather than just tell other people what they should do.

I'm under no illusion that the future will be a neat and tidy or desirable world. We will gain a lot of things through necessity and a lot of them through all sorts of fragile dysfunction - not because they're bad ideas but because they will inevitably be adopted in a chaotic, reactive way.

Although it is tempting to think of these natural landscapes as reflecting a stability in climactic and geologic forces, long periods of climactic and geophysical stability actually result in a rundown of the energy available to ecosystems and people. Geologically young regions with recent mountain building and volcanism tend to be much more biologically productive and have supported large populations of people despite their vulnerability to natural disasters. Geologically old regions (like most of Australia) tend to have low biological productivity and supported fewer people.

The Earth is a living, breathing entity. Without ongoing care and nurturing, there will be consequences too big to ignore.
