This book explodes with wonder and delight. Making use of remarkable scientific discoveries that transform our understanding of how natural systems work, George Monbiot explores a new, positive environmentalism that shows how damaged ecosystems on land and at sea can be restored, and how this restoration can revitalize and enrich our lives. Challenging what he calls his ecological boredom, Monbiot weaves together a beautiful and riveting tale of wild places, wildlife, and wild people. Roaming the hills of Britain and the forests of Europe, kayaking off the coast of Wales with dolphins and seabirds, he seeks out the places that still possess something of the untamed spirit he would like to resurrect. He meets people trying to restore lost forests and bring back missing speciessuch as wolves, lynx, wolverines, wild boar, and gray whalesand explores astonishing evidence that certain species, not just humans, have the power to shape the physical landscape. This process of rewilding, Monbiot argues, offers an alternative to a silent spring: the chance of a raucous summer in which ecological processes resume and humans draw closer to the natural world.
