Anthony Watts: "one of the most important posts ever on WUWT":
How to reverse desertification, stop global warming and feed the world. Raise livestock.
An amazing TED talk by Dr. Allan Savory:
Just think, livestock, the environmentalists' most hated food source. Dr. Savory must be right. His ideas are a winner on every level.
Update: Tim Ball's excellent response to Dr. Savory's presentation is here at WUWT. The comment thread greatly extends the debate surrounding Savory's claims.
