Starving Polar Bears in an Arctic Storm | Kingdom of the Polar Bears | National Geographic Wild UK

On solid ground, the largest land predators on the planet are reduced to scavengers. Every calorie counts. For now, tiny fish trapped in the early ice are the best this bear can do. An arctic fox also smells the fish, but doesn't stand a chance. The clock is ticking for all these bears, forcing some to take big risks. A desperate polar mom and her cubs can't wait for a more solid freeze. The ice is barely holding them up. Searching for food, they find only danger on the treacherous shoreline. There's also a hungry male lurking in the rolling ice flows. But he isn't looking to mate. He's hunting her cubs.
