The only ethical decision is to take responsibility for our own existence and that of our children.

I confess to a rare problem - gynekinetophobia, or the fear of women falling on me - but this is a rather mild illness compared with many affluent suburbanites, who have developed an almost total zoophobia, or fear of anything that moves. It is, as any traveller can confirm, a complaint best developed in the affluent North American, and it seems to be part of blue toilet dyes, air fresheners, lots of paper tissues, and two showers a day.

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.

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.

We have to rethink how we're going to live on this earth - stop talking about the fact that we've got to have agriculture, we've got to have exports, because all that is the death of us.

People question me coming through the American frontier these days. They ask, "What's your occupation?" I say, "I'm just a simple gardener." And that is deeply seditious.

I think we probably have a racial death wish. We don't understand anything about where we live, and we don't want to.
