Animals Are Bad for the Land

There seems to be a confusion there's a sense that animals are bad for the land. Alan Savory of course is South African Zimbabwe and I think yeah farmer who for many many years kind of bought into this idea that animals are destroying the land. He then all of a sudden had a revelation that in fact maybe animals were a source of growth for vegetation and positive for the land but he's kind of going uphill with this. Can you explain why that position is wrong? There's several ways to attack this we can start by talking about marriage say no way I don't want to touch that with married people, says John Sutter.
