Rewilding the world

George Monbiot in this Monday's Guardian: 

"Nature swiftly responds when we stop trying to control it. This is our big chance to reverse man's terrible destructive impact. Until modern humans arrived, every continent except Antarctica possessed a megafauna. In the Americas, alongside mastodons, mammoths, four-tusked and spiral-tusked elephants, there was a beaver the size of a black bear: eight feet from nose to tail. There were giant bison weighing two tonnes, which carried horns seven feet across."  http://www.guardian.co.uk/commentisfree/2013/may/27/my-manifesto-rewilding-world
