"I actually tried to find some other analogy around the world in modern history that provided an example of any country that had killed this many animals in a short period of time of only a hundred years, and came to the conclusion that in American history between 1800 and about 1920 we engaged in the largest destruction of animal life discoverable anywhere in world history. We take out 30 million , 15 million s, probably between a half-million and a million gray wolves, a hundred thousand grizzly bears once ranged across the west. They were down to fewer than 500 by the end of the 19th century. I mean, and this story happens over and over again with every animal you can think of. We drove grizzlies into the mountains, drove off the plains into the mountains, wiped out all the bighorn sheep that were in the bad lands and canyons of the great plains, all gone by 1906. And so it's this slaughterhouse that takes place. And it takes place, interestingly enough, at the same time that the conservation movement is creating these big game parks in Africa, in Kenya, in what becomes Tanzania, in South Africa. And yet, on our own great plains we don't do it... because the great plains becomes the part of the west that we privatize with homesteads and with ranches, and everyone who settles on the great plains basically regards all these animals as an annoyance that we need to get rid of..."
