Allan Savory：如何让世界的沙漠变绿、逆转气候变化

Allan Savory's TED talk arguing that desertification of grasslands can be reversed with holistic managed grazing, which he says would also help reverse climate change. TED notes that other scientists have challenged his claims.

Why HN likes it: HN commenters bring it up in climate and food threads as a hopeful, if contested, idea about grazing and soil carbon.

“This is the idea behind this fantastic TED talk”
