Stewart Brand on 4 Environmental Heresies

Stewart Brand, the author of the Whole Earth Catalog, was one of the leaders of the 60's environmental movement. He has recently been rethinking his positions on cities, nuclear power, genetic modification and geo-engineering. His ideas (Cities are Green! Nukes are Green! Gene modification is Green! Geoengineering is Probably Necessary!) have recently been published in WHOLE EARTH DISCIPLINE: An Ecopragmatist Manifesto a review of which is available here.

For the video inclined, he covers much the same ground in this TED talk.
