Polar bears in zoological facilities face significant welfare challenges from climate-adapted physiology in temperate environments, and zoo programs balance individual welfare with conservation education roles.
Polar bear welfare in zoos is one of the most challenging problems in zoological practice because these are large, wide-ranging animals with high cognitive needs that are difficult to meet within any feasible zoo environment. The prevalence of stereotypic pacing in polar bear exhibits reflects chronic environmental inadequacy that no amount of enrichment can fully compensate for if fundamental space and substrate needs are not met. Facilities with the best polar bear welfare outcomes have invested in very large, complex environments with naturalistic substrates, large water features for swimming, and diverse cognitive enrichment programs. The conservation education justification for polar bears in zoos requires genuine welfare — animals that demonstrate healthy behavior in appropriate environments provide more compelling conservation messages than visibly stressed individuals in inadequate exhibits.
