Stewart Brand has good values, and he asks good questions, and looks hard for intelligent answers. He is a national resource unto himself, and someone I have followed, off and on, for about 35 years. The Last Whole Earth Catalogue is still on my shelf -- and I click through it for a few hours every year.
Stewart is an old hippie. He (literally) drove the bus for the Electric Koolaid Acid Test, and if you have ever heard of Wendell Berry, then it is only because of Stewart Brand, who first gave him a platform for his "small is beautiful" theories of farming.
Stewart Brand has spent the last 40 years as a die-hard environmentalist. He has always put the Planet First, and he still does.
Watch this video and learn why Stewart is: 1) pro-city; 2) pro-nuke; 3) pro-genetically modified crops, and; 4) pro-geoengineering.
He is right on every point, whether that makes you happy or not.
