The power of Nature is great, because the natural structure is solid, three dimensional, not horizontal or two dimensional. Some of my mountain peach trees have kiwis climbing on them, and above the kiwi vines, there is a kind of melon. So three kinds of fruit exist together at different heights. I get one or two kilograms of fruit from one square meter of ground. This is a good sustainable yield.
Natural production is greater than man-made production, because the structure is solid.
Humans are destroying the power of Nature. We have only one fourth of the growing power of Nature left. We are not increasing fertility or production, but rather trying to prevent production from failing by using fertilizers. The world is digging itself into a bottomless pit with modern agriculture. The simple hearth of the small farm is the true center of our universe.
