The Grazing Revolution: A Radical Plan to Save the Earth (TED Books)
Allan Savory

Our planet is rapidly turning to desert. Once-lush grasslands, the source of precious food and water, are growing dry and bare. Rivers that used to flow year-round now run dry after the rains. Grazing animals want for food. What is causing this “desertification” of the earth, and how can we stop it? In The Grazing Revolution, biologist Allan Savory presents a solution that’s as radical as it is simple: huge herds of livestock, managed to mimic the behavior of the natural herds that once roamed grasslands centuries ago. Tracing his own story of discovery, Savory debunks common misconceptions and provides a vivid chronicle of the process by which he has seen scrubby wasteland revert to robust ecosystems. Our age-old agricultural practices are contributing greatly to the global climate change underway; Savory argues that by re-imagining these practices, we can reverse desertification and save the planet. 107 pages
