Another classic symbol of North American wildlife is the grizzly bear.Before the Eoropeans arrived,more than 50000 grizzlies wandered the American WEST.Today,due hunting and habitat desteuction,that number is closer to 1000.Furthermore,because grizzly bears have babies at a very slow rate,it takes many years for the population to grow. Most of the grizzly bears in the United States,excluding Alaska,live in Yellowstone and Glacier National Parks.As grizzlies are still protected by the ESA ,hunting them is illegal.As bear populations grow it becomes very important to prevent encounters between humans.People living in grizzly bear habitats are encouraged not to leave garbage lying around in case bears are attracted to the smell,and parks put up signs warning people not to stray off the path.Visitors are also warned not to alarm any bears they encounter
