I thought it was interesting too. I just hope he is right. He's been very wrong before. I wonder if there's enough livestock to simulate the once roaming herds of wild animals?

Even if he's found a way to return the effects of desertification, I still believe there are many forces involved that which we still don't understand.

I have a solution for "global warming." All we need to do is build a sun shade and put it in between us and the sun. It wouldn't have to be that large. We just need to reduce the solar energy coming to earth by a tiny amount. Presto, things cool down.

I pretty sure we could build an array of panels in space which cast a small unnoticeable shadow on earth.
