Once Upon the Future is an anthology of fictional stories written for children age 7-12 inspired by the research of six sustainability scientists. Each story is sprinkled with humor and magical realism, enlivened with beautiful illustrations, and complemented by educational resources. Using simple yet vibrant language, the stories convey insights on circular food economies, rural development and cultural textile traditions, forest commoning practices, biodiversity conservation and regeneration, youth in urban governance, and the importance of values and imagination for sustainability leadership.
