The book presents a novel strategy for addressing the major environmental and social problems of our time. It emphasizes transformative actions by individual citizens, both ordinary and extraordinary, rather than by government and other groups. It empowers a spectrum of solutions appropriate to people with varying interests, skills, political persuasions, and level of environmental and social commitment. The book draws on social and ecological theory to formulate a four-tiered stewardship strategy to transform communities, nations, and the planet. Key elements of this strategy are (1) individual actions that link people with nature and reduce human impacts on the planet, (2) effective communication to reduce political polarization and share solutions, (3) collaborations that integrate actions of multiple groups, and (4) political engagement to trigger needed transformations. The book builds on diverse visions and goals for the future of ecosystems and society: concern for future generations, a spiritual commitment to care for Creation and vulnerable people, a desire to sustain the best of nature and of cultures, and a concern about the security and well-being of communities, nations, and the world. This is not a book about what should be done. It is a book about what has been and can be done and a pragmatic strategy for tangible progress.
