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.

We are surrounded by insurmountable opportunities

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.

If you lend your skills to other systems that you don't really believe in, then you might as well never have lived. You haven't expressed yourself.

What is proposed herein is that we have no right, nor any ethical justification, for clearing land or using wilderness while we tread over lawns, create erosion, and use land inefficiently. Our responsibility is to put our house in order. Should we do so, there will never be any need to destroy wilderness.

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. We should cease to look to power structures, hierarchical systems, or governments to help us, and devise ways to help ourselves.

Permaculture principles focus on thoughtful designs for small-scale intensive systems which are labor efficient and which use biological resources instead of fossil fuels. Designs stress ecological connections and closed energy and material loops. The core of permaculture is design and the working relationships and connections between all things.
