Permaculture is a design system for creating sustainable human environments...Permaculture uses the inherent qualities of plants and animals combined with the natural characteristics of landscapes and structures to produce a life supporting system for city and country, using the smallest practical area.

The worst thing about permaculture is that it's extremely successful, but it has no center, and no hierarchy.

Another thing I find extremely eerie is that when people build a house, they almost exactly get it wrong. They don't just get it partly wrong, they get it dead wrong.

You don’t have a snail problem, you have a duck deficiency.

Trees are responsible for 3/4 of all rains

Too often, the pastoralist blames the weeds and seeks a chemical rather than a management solution; too seldom do we find an approach combining the sensible utilisation of grasshoppers and grubs as a valuable dried-protein supplement for fish or food pellets, and a combination of soil conditioning, slashing, and de-stocking or re-seeding to restore species balance.

You should never have gotten to the stage where you could see the last ancient forests! Just get out of there right now, because the lessons you need to learn are there. That's the last place you'll find those lessons readable.
