Wildlife experts say bear attacks are rising – but then, so is the number of people in bear country. Yellowstone National Park officials confirmed that a grizzly bear killed a hiker from Michigan. That's the second grizzly-caused death in the park this summer.
According to the Montana-based Center for Wildlife Information, run-ins with grizzly and black bears have increased in the last 20 years in North America. To some degree, that's expected. Bear populations have dramatically increased, and more people live and recreate in bear habitat now.
