The Grizzly Bear, America's largest, most spectacular predator, was on the brink of extinction in Yellowstone National Park until the 1975 Endangered Species Act made its recovery the biggest success story in conservation history. All wild carnivores need large ecosystems to survive, but when human economic interests, food, or small children encroach into their territory, conflicts between bears and people are inevitable. As we witness the impacts of environmental degradations and human encroachment on the last grizzly habitat in the lower 48 states, we ponder whether this American wilderness icon still faces extinction or if we will be able to co-exist with it.
