For more than 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 and of How To Thrive In The Next Economy. His previous book was the best-selling In the Bubble: Designing In A Complex World (MIT Press). John organizes conferences and festivals in which social innovators share knowledge.
