“We are part of nature and it is part of us. Everything about our species, from the shape of our teeth to the size of our brains, has been fashioned over millennia by our interaction with the plants and animals around us. What’s more, our sense of beauty and our greatest artistic achievements have been crafted in response to nature. Our yearning for wilderness is a hankering after the place we have come from, and from which we have become alienated in the headlong march of so-called progress.”
