Book excerpt: At a time of widespread environmental pessimism, Hope's Horizon goes on an inspirational offensive. In this entertaining and thought-provoking book, author Chip Ward tells of his travels among a new generation of activists who are moving beyond defensive environmental struggles and advocating pioneering, proactive strategies for healing the land. Chip Ward's three-year odyssey took him behind the scenes of efforts to reconnect fragmented habitats and "re-wild" the North American continent; the campaign to drain Lake Powell and restore Glen Canyon to its natural state; and the struggle to keep nuclear waste off Western Shoshone ancestral lands and, ultimately, to abolish all nuclear power and weapons. These movements, and the practical visionaries leading them, challenge readers with a new paradigm in which land is used in a spirit of collaboration with natural systems rather than domination of them. Broad in its sweep, Hope's Horizon uses its topical subjects as springboards for exploring how we can redefine our place in the world while restoring damaged habitats, replenishing lost diversity, and abandoning harmful technologies. Lively, literate, and free of the grimness that characterizes so much environmental writing, Hope's Horizon will change the way readers see the world. It makes complicated concepts and issues accessible, and wild ideas compelling. And while the book's starting point is a hard-nosed indictment of humanity's failed stewardship of the earth, the stories that follow tell of catalytic optimism and ecological wisdom in the face of self-destructive habit and blind pride.
