The organism in the alpine biome that was once nearly extinct and now is on the endangered species list is the Grizzly bear. Grizzly bears are perhaps the highest-profile endangered animal of the alpine biome. At the current state, only 1.000 – 1.2000 grizzly bears are remaining in North America from once estimated 50.000. Part of the reason grizzly bears became endangered is the shortage of the food.
