A man in Canada** suffered severe injuries after jumping onto a polar bear to protect his wife from an attack in the early hours of Tuesday. The couple had been looking for their dogs when they encountered the bear in their driveway. The bear lunged at the woman, but the man intervened, taking the brunt of the attack and suffering injuries to his arm and legs. A neighbor arrived and shot the bear, which later died from its wounds. Climate change is causing temperature fluctuations in the ocean, affecting how far bears can roam inland, making such attacks more common.Polar bears rarely attack humans, but when they do, it's often because they're hungry, young, or unwell. The community maintained patrols to ensure no other bears were present.
