We are sufficient to do everything possible to heal this Earth.

Brambles, in particular, protect and nourish young fruit trees, and on farms bramble clumps (blackberry or one of its related cultivars) can be used to exclude deer and cattle from newly set trees. As the trees (apple, quince, plum, citrus, fig) age, and the brambles are shaded out, hoofed animals come to eat fallen fruit, and the mature trees (7 plus years old) are sufficiently hardy to withstand browsing. Our forest ancestors may well have followed some such sequences for orchard evolution, assisted by indigenous birds and mammals.

Once you've said to yourself, "But I'm not using my physics in my house," or "I'm not using my ecology in my garden, I've never applied it to what I do," it's like something physical moves inside your brain. Suddenly you say, "If I did apply what I know to how I live, that would be miraculous!" Then the whole thing unrolls like one great carpet. Undo one knot, and the whole thing just rolls downhill.

Anything that's any good is self-perpetuating.

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.

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

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.
