For thirty years John Thackara has traveled the world in his search of stories about the practical steps taken by communities to realize a sustainable future. He writes about these stories online, and in books; he uses them in talks for cities, and business; he also organizes festivals and events that bring the subjects of these stories together. John is the author of a widely-read blog at designobserver.com and of the best-selling In the Bubble: Designing In A Complex World (MIT Press) - also translated into nine languages. As director of doorsofperception.com, John organizes conferences and festivals in which social innovators share knowledge. He has lectured in more than forty countries.
