“Walking in an ancient forest or snorkeling in a coral reef, I have felt an aliveness, a sense of many interlocking pieces clicking together into a living and dynamic whole. These are places that naturally exude abundance. Sadly, this feeling was lacking in any human-made landscape I had experienced. Natural landscapes seem so rich; they seethe with activity; they hum with life in comparison to our own. Why is it that nature can splash riotous abundance across forest or prairie with careless grace, while we humans struggle to grow a few flowers? Why do our gardens offer so little to the rest of life? Our yards seem so one-dimensional, just simple places that offer a few vegetables or flowers, if that much. Yet nature can do a thousand things at once: feed insects and birds, snakes and deer, and offer them shelter; harvest, store, and purify water; renew and enrich the soil; clean the air and scent it with perfume; and on and on.”
