Not the cow, but the how.

I believe that this is true because of the many points that he brings up. He shows that animal grazing is important to the ecosystem and that it is important to keep things in check. He also showed us his method of grazing that would make it possible for better ecosystems and fewer gas emissions. I think that a way that they could make this more efficient is if they could try to use more than traditional livestock since animals have different effects on different places. I do believe though, that he is doing the right thing because of the results that he was able to show us.
