The problem is that as soon as a bear gets a taste of anything human -- from drinking out of your garden hose to eating out of the garbage -- forest authorities have to take it out. Otherwise, it will never leave; getting food and water from people's houses, camps, toilets, etc. is way easier than wasting an entire morning trying to catch fish or desperately licking honey out of a pulsating beehive.
And once a bear associates humans with food, it's a super short step to it seeing people as food, and those morsels of delicious trash get replaced with delightful mouthfuls of terrified person face. And so, Allena was digging out an irrigation spring on her Kern County ranch in the summer of 2008 when she came face to face with a black bear, charging her down with the highest level of "all kinds of pissed off" stamped across its face. It came seemingly out of nowhere, perhaps erupting from a fold in space-time, and was on her before she even had time to react.
In the weeks prior, Allena's son had been trying to teach her some MMA moves, as that had been his thing at the time, and he felt his mom would benefit from some righteous grappling training. However, she quickly discovered that it's difficult to remember secondhand takedown techniques when a) there's no coach in your corner, and b) your opponent is a motherfucking bear. So Allena went for the one self-defense move that's universal in all areas of combat, whether your attacker is a mugger or a rampaging wild animal -- gouge its goddamned eyeballs out with your fingernails.
Your goal is to have that not be your blood.
This was a pretty risky move on Allena's part, because the bear had already started eating her face, but she landed the shot (and in fairness, every move is a risky one when you're pinned beneath an angry bear). The bear was stunned but by no means finished with its assault on her person, so Allena used the few seconds' worth of distraction she'd earned by jabbing it in the eyes to tag in some assistance.
