To accumulate wealth, power or land beyond one's needs in a limited world is to be truly immoral, be it as an individual, an institution, or a nation-state.

If you're dealing with an assembly of biological systems, you can bring the things together, but you can't connect them.

Compressed air can provide limitless amounts of clean energy using technology we have had for hundreds of years.

It’s a revolution. But it’s the sort of revolution that no one will notice. It might get a little shadier. Buildings might function better. You might have less money to earn because your food is all around you and you don’t have any energy costs. Giant amounts of money might be freed up in society so that we can provide for ourselves better. So it’s a revolution. But permaculture is anti-political.

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.
