Polar bears require vast Arctic territories and are deeply adapted to sea-ice environments. Their welfare in captivity raises serious ethical questions about the limits of zoo keeping.
Polar bear welfare in captivity is among the most challenging ethical issues in modern zoo management. The species is cognitively sophisticated, evolved for hunting over vast ice territories, and shows consistent welfare problems in captive environments that cannot be resolved by enclosure size within zoo constraints. Stereotypic pacing — observed in the vast majority of captive polar bears — is a clear welfare indicator of unmet needs. The conservation justification is also questioned: captive breeding has not produced meaningful reintroduction capacity. Welfare-honest assessment of polar bear captivity should acknowledge these limitations rather than overstating conservation benefit.
