Polar bears are ice-adapted marine mammals facing both wild population crisis from climate change and welfare challenges in zoo settings that cannot replicate Arctic conditions. Their welfare requires specialized cold habitats and extensive enrichment.
Polar bear welfare in zoos is challenged by the fundamental mismatch between their ecological needs and captive environments. Their evolved motivation for long-distance travel and swimming cannot be met in any zoo setting. Stereotypic pacing is near-universal in zoo polar bears and indicates chronic behavioral frustration. Cold water pools, ice provision, and hunting enrichment — frozen prey items, fish hidden in pools — provide partial mitigation. The conservation value of zoo polar bear programs is debated; the species cannot be meaningfully bred in sufficient numbers to address wild population decline. Welfare programs that honestly assess and minimize stereotypic behavior through enrichment provide the most ethical management approach.
