A research-based proposal for greening the world’s deserts

In a TED talk given a few years ago, a scientist named Allan Savory puts forth an interesting proposal for reversing desertification and climate change. After having worked in the field his whole life, the solution he found is an unlikely one: grazing livestock. They are commonly thought to destroy the land and contribute to global warming, but they can in fact, help restore its vegetation and thus begin to reverse global warming, if the grazing process is done correctly. Allan goes into more details in his talk, which I invite you to watch. What he proposes is a low cost solution that involves forming large herds and moving them over the land in a sigmoid pattern so they never overstay in one spot. His methods have successfully worked on multiple continents to reverse desertification and restore grasslands, so they’re proven. And even if his proposal has its detractors, who say the livestock will emit more greenhouse gases, you can’t argue with the results, which are an almost magical revival of plants, trees and water in those places where his methods are put into place.
