The important thing is not to do any agriculture whatsoever, and particularly to make the modern agricultural sciences a forbidden area - they're worse than witchcraft, really.

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

A house should look after itself - as the weather heats up the house cools down, as the weather cools down the house heats up. It's simple stuff, you know? We've known how to do it for a long time.

That we don't design agriculture to be sustainable is totally eerie. We design it to be a disaster, and of course, we get a disaster.

Permaculture is a philosophy of working with, rather than against nature; of protracted and thoughtful observation rather than protracted and thoughtless labor; and of looking at plants and animals in all their functions, rather than treating any area as a single product system

There are only four things in all cleaners - whether it's shampoo, laundry detergent, whatever.You buy them in bulk and you mix them up properly, and they all work. It doesn't matter if they call the stuff ecologically friendly or have dolphins diving around on the label - it still has these damn four things in it. Anything else is just unnecessary additions to make it smell good or color it blue when it goes down the toilet.

The end result of the adoption of permaculture strategies in any country or region will be to dramatically reduce the area of the agricultural environment needed by the households and the settlements of people, and to release much of the landscape for the sole use of wildlife and for re-occupation by endemic flora.
