Answer:
Actually in a National Park like Glacier its the "bears habitat" first, obviously human safety is a must but if you've even seen the beauty of Glacier firsthand you would know that. A protected area like the park is helping preserve areas of land where the wild animals can remain for hopefully generations, although there is some debate about that. I would be very upset if the government took National Parks and sold them off for "human expansion". Visit Montana, the Dakotas, Wyoming, heck even Iowa and see the vast open spaces, overrowing is not an issue. Just my two cents from Ohio
