Stewart Brand: Rethinking Green
This talk launches Brand's new book: Whole Earth Discipline: An Ecopragmatist Manifesto. His argument is that taking account of the emerging global forces of climate change, urbanization, and biotechnology forces a rethink of some traditional environmental positions. Cities are Green, with huge room for improvement. Nuclear power is Green, with better still to come. Genetic engineering is Green and shows potentially revolutionary promise. Direct intervention in the climate---geoengineering---may be necessary. The classic environmental project of restoring natural systems has to step up in scale and deepen the quality of its science and engineering.
