Polar bear’s swipe force is so powerful that kill a human or even cause several injuries. The main factor behind the strength of polar bears is their consumption of high amounts of meat. According to some estimates, a polar bear can eat between 10% to 20% of their body weight daily. It means that if a bear weighs between 300 to 800 kg, it will consume 30 to 80 kg of meat per day.

Another factor contributing to their strength is their large body size. An adult polar bear can be between 8 to 10 feet in length. The tallest polar bear ever recorded in history was 12 feet tall and weighed about 2209 lbs. This bear was shot 64 years ago in Alaska.

Why Are Polar Bears So Dangerous?

Polar bears are considered dangerous to humans primarily due to their predatory nature, size, strength, and the fact that they view humans as potential prey. Generally, polar bears’ attacks on humans are rare, but in January 2023, a fatal incident was recorded in which a polar bear killed one woman and her 1-year-old child in Alaska.

The bear was later killed by Alaska residents due to concerns over human safety and their aggressive nature. Let’s not forget that the largest polar bear on record was also shot in Alaska back in 1960. Another polar bear attack killed two people in July 2023 that was going to trip.

On August 5, 2011, there was another bear attack in which a polar bear killed one person and injured four others. The bear was later killed by one of the individuals who was also injured in the attack.

Here, below are some points that indicate why polar bears attack humans:

  • Apex Predators: Polar bears are the dominant predators in the Arctic region, and they are extremely powerful hunters with no natural predators. Their primary prey includes seals, especially ringed and bearded seals. Therefore, whether it is a human or any other animal, they will catch and eat them.
  • Territorial Behavior: Polar bears are also territorial, just like hippos, especially when it comes to food sources. If a polar bear perceives a human as a threat or as potential competition for food, it may become aggressive.
  • Scarcity of Food: Climate change has affected polar bears’ primary food sources. As a result, bears that have not eaten more than a week may become more desperate and willing to approach urban areas or individuals in search of food.

Many past incidents were recorded due to bear attacks, many of them occurring in residential areas. It means that polar bears were coming in search of food, and they attacked people out of curiosity. And sometimes, attacks occur in the Arctic region when people embark on trips to these areas.
