This is the sort of black and white rhetoric that I think does not do a service to the reality involved. Of course you are correct that overgrazing is a problem, but to go from that to "using livestock to live in places we otherwise couldn't is something we do to destroy the environment" is plain wrong. I would instantly concede your point if you could moderate it to "we need to stop overdoing things", which I think is compatible with what we both see and still has merit.
