Imagine being stranded without a reliable path to your dinner – that’s the reality for the iconic Polar Bear as its frozen hunting ground disappears beneath its paws. These bears rely almost entirely on sea ice to hunt seals, rest, and raise their young, meaning that the rapid loss of ice is not just a challenge – it’s an existential threat.

Melting Ice Means Fewer Meals
Polar bears depend on sea-ice platforms to catch seals, their primary food source. As the ice melts earlier each year and reforms later, bears have shorter hunting seasons and must rely more on stored fat or less nutritious land-based foods.
More Swimming, Higher Risk
With less stable ice, polar bears are forced to swim longer distances between ice floes or from shore to hunt. This extra effort burns more energy and increases the risk of drowning or exhaustion, especially for young bears.
Thinner Ice, Weaker Habitat
The older, thicker ice that once supported hunting and resting is being replaced by younger, thinner ice that breaks up more easily and shifts under storms. Without stable ice, bears lose safe platforms for feeding and mating.
Population Declines Are Under Way
Scientific modelling shows strong links between sea-ice loss and reduced polar bear populations. A study found that for the Western Hudson Bay subpopulation, declines of 30 per cent or more are likely within three bear generations if current trends continue.
Underlying Risks Are Amplified On Land
When polar bears spend more time onshore due to missing ice, they face new threats: increased contact with humans, exposure to pollutants and pathogens, and fewer opportunities to build the body fat needed to survive lean periods.
What Their Future Holds
Experts agree that climate change is the chief risk to polar bears, more so than hunting or local disturbances. Without significant reductions in greenhouse-gas emissions, many bear populations could disappear entirely by the end of the century.
Melting ice isn’t just reshaping the Arctic – it’s reshaping the fate of the polar bears themselves. Their future hinges on the survival of the sea-ice ecosystems that have supported them for thousands of years.
