A World Made of Cities: “At present there’s little awareness among environmentalists that growing cities are where the action and opportunities are, and there’s little scientific data being collected. I think a large-scale, long-term environmental strategy for urbanization is needed, two-pronged. One, take advantage of the emptying countryside (where the trees and other natural systems are growing back fast) and preserve, protect, and restore those landscape in a way that will retain their health when people eventually move back. Two, bear down on helping the growing cities to become more humane to live in and better related to the natural systems around them. Don’t fight the squatters. Join them.'” (radar.oreilly.com)
