You’ve seen the Coca-Cola commercials. Those fuzzy, snowy giants look almost cuddly, right? The reality is a lot grimmer. In the high Arctic, they aren't looking for a soda; they're looking for calories. And honestly, they don't care where those calories come from. When people ask if polar bears eat people, the short answer is yes. They are the only species on Earth that will actively stalk a human being as a legitimate food source.
It’s not like a grizzly bear attack where the animal is usually just surprised or defending its cubs. With a polar bear, it’s often a hunt. They are "hyper-carnivorous." That means their diet is almost entirely meat. In places like Churchill, Manitoba, or Longyearbyen in Svalbard, this isn't some campfire ghost story. It’s a daily safety protocol. You don't leave your car door locked in Churchill because someone might need to dive inside to escape a 1,200-pound predator that's been tracking them for three blocks.
The Biology of a Marine Mammal Hunter
Technically, Ursus maritimus is classified as a marine mammal. They spend most of their lives on the sea ice. Their entire biological "hardware" is designed to kill seals. A ringed seal is a concentrated ball of blubber and protein. That’s what the bear wants. But the ice is melting. It’s happening faster than most models predicted, and that brings the bears onto land.
When a bear is "food-stressed," its inhibitions vanish. Dr. Ian Stirling, one of the world’s leading polar bear scientists, has documented how these animals adapt to changing environments. If they can’t find a seal, they’ll look for alternatives. Ground-nesting bird eggs. Kelp. Trash. And, unfortunately, humans. They are incredibly patient. A bear might watch a camp for days, gauging the movement of the people inside, waiting for that one moment when someone walks behind a shed without a rifle.
They are silent. For such a massive animal, they move like ghosts. Their paws are huge, acting like snowshoes, and the fur on the bottom muffles the sound of their footsteps on the crunching snow. You won't hear them coming. You’ll just feel the weight.

Real Encounters: When Polar Bears Eat People
We have to look at the data to understand the frequency. A 2017 study published in the Wildlife Society Bulletin analyzed 73 confirmed polar bear attacks on humans between 1870 and 2014. That sounds like a small number over a long period. But here’s the kicker: the frequency is ramping up.
Take the 2018 tragedy in Arviat, Nunavut. Aaron Gibbons was out with his children on Sentry Island. A bear approached. He put himself between the predator and his kids so they could run to their boat. He didn't have his rifle on him at that exact second. He died saving them. This wasn't a "defensive" bite. The bear was predatory.
Then there’s Svalbard. In 2020, a Dutch man named Johan Kootte was killed in his tent at a campsite near Longyearbyen. The bear dragged him out. This happened in the middle of the night. In that part of the world, you don't go hiking without a high-caliber rifle or a flare gun. It’s the law. Why? Because the authorities know that a hungry bear doesn't see a "tourist." It sees a slow, weak animal with a high fat content.
Why the risk is spiking
- Sea Ice Loss: The "hunting platform" is literally disappearing. Less ice means bears spend more time on land near human settlements.
- Human Encroachment: More people are heading north for mining, oil, and tourism. More people, more problems.
- Habituation: Bears are smart. If they find food once near a town, they’ll come back. They associate the smell of cooking or garbage with a meal.
- The "Thin Bear" Factor: Most attacks are carried out by sub-adult males or very old bears. These are the ones who are starving and desperate.
The Psychological Reality of Being Prey
It’s a weird feeling. Most of us live in a world where we are at the top of the food chain. We go to the grocery store. We walk the dog. In the Arctic, that hierarchy is flipped on its head. You are part of the ecosystem, and the ecosystem is hungry.
Bears have a sense of smell that is borderline supernatural. They can smell a seal through three feet of solid ice from over a mile away. Think about that. If you're frying bacon in a remote cabin, every bear within a five-mile radius knows exactly where you are. They aren't "mean." They don't have malice. They are just incredibly efficient biological machines trying to survive in the harshest environment on the planet.
How to Stay Alive in Bear Country
If you ever find yourself in the high north, you need to change your brain. Forget what you know about black bears. You can’t "scare off" a hungry polar bear by banging pots and pans, though sometimes a loud noise helps initially. If it's decided you're lunch, you're in a life-or-death fight.
Experts like those at Polar Bears International emphasize "bear-aware" behavior. This means using deterrents before things get physical. Bear spray is great, but in the Arctic, the wind is often so strong it’ll just blow the spray back into your own face. Not ideal.
Most locals rely on "bear bangers." These are small pyrotechnic charges that make a massive "bang" to scare the animal. But if that doesn't work? You need lead. A .300 Winchester Magnum or a 12-gauge shotgun with slugs is the standard. It’s a tragedy when a bear has to be shot, but when polar bears eat people, the community usually has no choice but to eliminate the problem animal.
Survival Steps to Remember
- Never walk alone at night. Polar bears are most active in low light.
- Keep your perimeter clear. Don't leave out seal meat, dog food, or even scented toiletries.
- Carry a deterrent. If you don't have a firearm, you must have a flare gun or bear spray at the very least.
- Watch the wind. A bear will usually approach from downwind so it can smell you before you see it.
- Look for "day beds." These are depressions in the snow or dirt where a bear has been resting. If you see one that’s still warm, leave. Fast.
The Future of Coexistence
The conflict is only going to get worse. As the climate shifts, the boundary between "human space" and "bear space" is blurring. In Novaya Zemlya, Russia, they had a literal "invasion" of dozens of polar bears into a town a few years ago. They were scavenging in the local dump and wandering into apartment buildings.
We have to find ways to keep them away without killing them. This involves better garbage management, using radar systems to detect bears approaching a town, and "bear patrols" that use non-lethal means to haze them back to the ice.

It’s a balance. We want to save the species, but we also want to stay alive. Understanding that polar bears eat people isn't about demonizing them. It’s about respecting what they are: the most formidable land predator left on Earth.
Actionable Safety Measures for Arctic Travel
If you are planning a trip to a northern frontier, do not wing it. Research the specific bear density of your destination. Hire a local guide who is armed and experienced. Most importantly, understand that a polar bear’s curiosity is often a "test." They might approach slowly, circling, seeing how you react. If you run, you trigger their chase instinct. You cannot outrun them. They can hit 25 miles per hour on uneven ice.
Stay vigilant. Keep your eyes on the horizon. In the white-on-white world of the Arctic, a bear looks like a slightly yellowish bump in the snow until it starts moving. By then, it might already be too late.
To stay truly safe, follow these immediate actions:
- Consult Local Authorities: Always check in with the local conservation office or police to see where recent sightings have occurred.
- Hard-Sided Containers: Store all food in bear-proof, hard-sided containers, never in a tent.
- Tripwires: In remote camps, use perimeter tripwire alarms that fire a blank or a flare to wake you up before the bear reaches your tent.
- Group Integrity: Stay close together. A group of four humans looks a lot more intimidating to a bear than a lone hiker.
The Arctic is a beautiful, brutal place. Respect the bear, and you might just make it home to tell the story. Forget that respect, and you become part of the food chain. It's really that simple. Over the next decade, expect to see more headlines about these encounters as the ice continues to thin. Being informed is the best defense we have.---
