Polar bears face a dual welfare challenge: their wild populations are threatened by climate-driven sea ice loss, while captive polar bears in zoos struggle with the constraints of environments designed for temperate climates.
Polar bear welfare presents one of the most difficult cases in zoo ethics. These are wide-ranging, Arctic-adapted predators whose physical and behavioral needs are among the most demanding to meet in any zoo setting. The welfare costs of captivity — stereotypic pacing, restricted movement, incompatible social pairings, inadequate environmental conditions — are well-documented. The conservation argument for maintaining captive populations faces additional challenges: unlike some species, polar bears have nowhere to be reintroduced to until the sea ice is restored, which requires addressing climate change at a scale no zoo program can influence. Honest assessment of polar bear welfare in captivity is overdue.
