Polar Bear Welfare: Ice, Starvation, and the Climate Emergency

Polar bears are the iconic species of Arctic climate change, and their welfare is directly threatened by the loss of sea ice they depend on for hunting. Individual suffering from starvation and conflict is increasing as their habitat shrinks.

Key Facts

Polar bears (Ursus maritimus) depend on sea ice as a platform for hunting ringed seals — their primary prey
Arctic sea ice extent has declined approximately 13% per decade since satellite records began in 1979
The global polar bear population is estimated at 20,000–31,000, with 8 of 19 subpopulations in decline
Longer ice-free seasons force polar bears to fast on land for extended periods, depleting fat reserves
Starving polar bears increasingly enter human communities in search of food, creating dangerous conflict
Thin females produce fewer and lighter cubs with lower survival rates — a compounding population welfare concern
Some subpopulations in the southern Beaufort Sea are experiencing the earliest documented population declines
Polar bear welfare cannot be separated from climate policy — reducing Arctic warming is the only effective intervention

Welfare Considerations

Polar bear welfare is inseparable from climate change. Longer ice-free seasons mean longer fasting periods for bears that cannot hunt seals from land — and starvation is a prolonged, distressing welfare state for a large warm-blooded mammal. Documented cases of severe emaciation, including the viral 2017 photographs of a starving Baffin Island bear, illustrate welfare consequences that are increasingly common across declining subpopulations. Females in poor body condition produce cubs they cannot adequately nourish — cubs that are lighter, weaker, and less likely to survive their first year. Community conflict increases as hungry bears enter settlements, leading to management kills that cause individual welfare harm while reflecting the population-level crisis. In captivity, polar bear welfare is also concerning — large, intelligent animals that swim vast distances in the wild are profoundly restricted by even the largest zoo exhibits. Climate action is the only effective large-scale polar bear welfare intervention.

What You Can Do

Prioritise climate action as the most important polar bear welfare intervention — contact your elected representatives
Support Polar Bears International in their research, advocacy, and community coexistence programmes
Advocate against Arctic oil and gas development that would further damage sea ice habitat and polar bear welfare
Support Indigenous community-based monitoring and coexistence programmes in polar bear range areas
Raise awareness that polar bear welfare is a climate issue — individual suffering is increasing now, not in the future
