If environmental destruction continues at its current rate, a third of all plants and animals could disappear by 2050 -- along with earth's life-support ecosystems, which provide food, water, medicine, and natural defenses against climate change. Now Caroline Fraser offers the first definitive account of a visionary crusade to confront this crisis: rewilding. Breathtaking in scope and ambition, rewilding aims to save species by restoring habitats, reviving migration corridors, and brokering peace between people and predators. A "methodical, lyrical" (Sacramento News & Review) story of scientific discovery and grassroots action, Rewilding the World offers hope for a richer, wilder future. -- P. [4] of cover.
