Polar bears have vast natural home ranges and complex behavioral repertoires that are extremely difficult to accommodate in zoo settings, raising significant welfare questions.
Polar bears present some of the most challenging welfare questions in zoo management. Their evolved lifestyle involves vast movement across sea ice in pursuit of seals — behavioral drivers that are irreconcilable with even large zoo environments. The high prevalence of stereotypic pacing in captive polar bears signals chronic psychological distress. Some zoos have made significant investments in large, complex naturalistic enclosures that substantially improve welfare, but even these cannot replicate the environmental richness of the Arctic. The justification for polar bear captivity increasingly rests on conservation education value and potential for climate change awareness rather than individual animal welfare, which remains inherently compromised.
