Our guest today, Dr. Caroline Fraser, has written the first definitive account of a visionary campaign to confront ecological crises, entitled Rewilding the World, Dispatches from the Conservation Revolution. Breathtaking in scope and ambition, rewilding aims to save species by restoring habitats, reviving migration corridors, and brokering peace between people and predators.

Traveling with wildlife biologists and conservationists, Caroline reports on the vast projects that are turning Europe's former Iron Curtain into a greenbelt, creating transfrontier Peace Parks to renew elephant routes throughout Africa, and linking protected areas from the Yukon to Mexico and beyond.
