Polar bears in zoos face welfare challenges from tropical and temperate climates incompatible with their physiology. As climate change threatens wild populations, the welfare implications of maintaining polar bears in captivity are intensifying.
Polar bears in inadequate captive environments show high rates of stereotypic pacing behaviour indicating significant psychological suffering. Maintaining bears in hot climates without appropriate cooling, environmental complexity, and cognitive enrichment causes chronic welfare problems. As wild populations face existential climate threats, decisions about captive polar bear welfare have increasing conservation significance.
