With natural light and a breeze that passes through, John Hardy's dream of building a green school comes alive in Bali. Created with bamboo architecture, no walls and a diverse range of teachers, this school not only teaches reading, writing, and arithmetic but also teaches how to reconnect to nature, endeavoring to develop future green leaders from 25 different countries. This 14 minute TED talk shares Hardy's amazing journey from being lit up by a small idea to the culmination of a beautiful model with these principles at its core: be local, let the environment lead, and think about how your grandchildren might build.
