Polar bears are among the most challenging species to maintain in captivity with good welfare. Their wide-ranging Arctic adaptations make captive life inherently limiting, raising important ethical questions.
Polar bears represent a genuine ethical dilemma in zoo keeping. Their natural lifestyle - roaming Arctic sea ice, hunting seals over vast distances, experiencing extreme seasonal variation - is so far removed from what any captive facility can provide that welfare compromises are inevitable and substantial. The high rates of stereotypic behavior in captive polar bears are behavioral indicators of chronic stress and frustrated natural drives. The conservation argument for captive polar bears is also weak given their habitat-specific ecology. Many leading zoo associations now advise against keeping polar bears. The question is whether the educational value of captive polar bears justifies their welfare costs.
