How can we create a just, healthy and humane world? What is the path to developing sustainable energy, food, transportation, production, construction and other systems? What's the best strategy to end poverty and ensure that everyone has equal rights? How can we slow the rate of extinction and restore ecosystems? How can we learn to resolve conflicts without violence and treat other people and nonhuman animals with respect and compassion? The answer to all these questions lies with one underlying system - schooling. To create a more sustainable, equitable and peaceful world, we must reimagine education and prepare a generation to be solutionaries - young people with the knowledge, tools and motivation to create a better future. This book describes how we can (and must) transform education and teaching, create such a generation and build such a future.
