The second installment in this series was filmed on the Great Plains. It shows (a) how the land has changed since ranchers and farmers replaced the Indian tribes, and (b) how the systematic killing of wildlife, especially prairie dogs, has upset the ecology of the region and is threatening several species with extinction. This episode contends that mass killing of wildlife on the Plains is no longer necessary because the population of most species has declined drastically. Included are illustrations of how various animals are intentionally killed, and interviews with two ranchers, one who believes such killing is necessary to protect his stock, and one who agrees with the creators of this series.
