180 seconds (3 minutes) is a hilarious overestimation of any fighter's ability. Unless you're counting the time it takes to bleed out.

Worked in Yellowstone for a summer.

Spent some time with the rangers. They got all sorts of questions...

Like which handgun caliber would be best to defend oneself from a bear.

Essentially, the ranger broke it down stating there was a weakness in the skull about the size of a bullet that you had to hit directly to have a chance of dropping a bear with a handgun. While its coming at you and pissed/hungry.

So essentially, you've just pissed off the bear before it gets it claws on you.

Well placed slugs from shotguns, rifle rounds, and preferably (according to the ranger in question) a tranquilizer to re-home the bear away from people. That being said, the bears are tracked to an extent and bears who show repeated behavior endangering themselves/tourists tend to be exterminated, sadly.

Hand to claw combat? Human is going down.

This is why in the past, when bears were hunted, they were hunted in their dens during hibernation - at the end of spears to keep that hungry bear as far away as possible from your soft easily rent flesh.

They may kill SEAL with a slap but how many polar bear slaps does it take to kill members of other special forces?

Here is a black bear, a grizzly, and a polar bear.

And Marcie.

Fighting bears isn’t that common of an encounter. I’d be more worried about deer and coyotes or even a single cougar than the off chance of encountering a bear. They will definitely fuck you up but it’s not like they are starting their day to be like “Imma go murder a human” in the same way other urban-adjacent animals are—I think they just wanna get that sweet sweet pick-a-nic basket.

Bear is black, fight back.

Bear is brown, turn around.

Bear is white, say good night.

Also, one of the few animals that will hunt humans for food

Do not – and I really cannot stress this enough – give any of those bears cocaine

What kind of bear is that wearing the sunglasses?

Fun fact: Grizzlies and Polar Bears are the same species according to the Biological Species Concept.

Meaning they interbreed in the wild (somewhat rare), and produce viable offspring that can have babies as well.

We’re actually noticing this happening more and more with climate change. As Grizzly populations move further and further north, they’re encountering polar bears more often and are more likely to mate. Some scientists actually think within the next couple centuries due to arctic sea ice pretty much disappearing polar bears will either go extinct, or interbreed with grizzlies so much that there isn’t a “pure” polar bear left. Most likely a mix of both.
