““From am overall eclsyste,s perspective, if you're going to have 10million human beings trying to share an environment with other life-forms, it's much better to crowd all 10 million of them a hundred square miles than it is to spread them out, edge-city style, over a space ten or a hundred times that size. If we're going to survive as a planet with more than 6 million people without destroying the complex balance of our natural ecosystems, the best way to do it is to crowd as many of those humans into metropolitan spaces and return the rest of the planet to Mother Nature.””
