The grizzly bears of Yellowstone National Park were once habituated to human presence, surviving on trash intentionally left by visitors. Since the reversal of the park's policy in 1972, the bears have learned to hunt, ending their dependence on humans. The grizzlies' return to the wild has positively impacted their survival, but has been detrimental to ranchers in areas surrounding Yellowstone. In this video segment from Nature, meet a cattle rancher who was unable to prevent the bears from attacking his livestock.
