I'm honestly surprised that there isn't more bear incidents myself, shocked really when you think of all the vacationers around the NW corner that have nearly zero clue about Grizzlies.
I'm no biologist, and certainly don't spend as much time in grizzly country like others, but bears maybe actually have a lot more fear of humans than most think?
Look at all the dumb arse people managing to get ran over by bison in Yellowstone, you'd think Grizzlies would have a field day with that many clowns running around up there all summer long.
There have been steps taken to lower the encounters. Back in the "good old days" people fed bears from vehicles in Yellowstone and a high percentage of the bears were food conditioned at garbage dumps in the Park. More education near areas where bears frequent, secure garbage cans, securing food, bearproof boxes in the backcountry, better education of people, bear spray, rubber bullets, the list goes on and on.
All of these things combined have, and will do more to protect both humans and bears than killing a few each year via legal hunting, IMO.
Seems to work pretty well over-all as we have a recovered bear population and not many really bad encounters.
The bad thing is, grizzly bear mauling's are a lot like airplane crashes, when things go bad, they go really bad. But, over-all both are grossly unfounded fears statistically speaking. Its the thought that you may get mauled by a grizzly or have your plane crash that creates unreasonable fear.
I'm not going to stop hunting in areas that have grizzlies and I'm also not going to stop flying in airplanes either.
