Polar Bear Welfare: Climate Change and Captivity

Polar bears face an existential welfare crisis from climate change melting Arctic sea ice, while captive populations raise welfare questions about keeping highly specialised animals in zoo environments.

Key Facts

Polar bears require sea ice to hunt their primary prey, ringed seals
Arctic sea ice extent has declined by approximately 40% since 1979
Body condition of polar bears in Hudson Bay has declined as ice-free seasons lengthen
Captive polar bears frequently show stereotypic pacing in zoo environments
A wild polar bear's home range can exceed 500,000 square kilometres

Welfare Considerations

Wild polar bears experiencing food scarcity from ice loss face prolonged fasting, nutritional stress, and reproductive failure. Climate projections suggest summer ice-free Arctic by 2050, threatening population viability. Captive polar bears in zoos cannot be provided anything approaching natural conditions — their ranging needs and hunting requirements are impossible to replicate. Captive populations exist for public education but their welfare is chronically compromised by spatial restriction.

What You Can Do

Support climate action as the primary polar bear welfare intervention
Donate to Polar Bears International and conservation science programmes
Oppose oil drilling in Arctic regions critical to polar bear habitat
Engage with zoo accreditation bodies about improving polar bear enclosure standards
Reduce personal carbon footprint and advocate for national climate policy
