Polar bears in zoos face profound welfare challenges. Their natural history as wide-ranging Arctic predators makes them particularly difficult to house in ways that meet their behavioral and psychological needs.
Polar bears are widely recognized as one of the species least suited to zoo captivity. Their need for vast ranges, complex hunting behavior, and a specific Arctic environment cannot be meaningfully replicated in zoo conditions. The high prevalence of stereotypic pacing and swimming patterns in zoo polar bears is a reliable welfare indicator that habitats are inadequate. While some zoos have invested in larger, more complex enclosures with swimming pools, ice, and varied terrain, fundamental limitations remain. Progressive zoos are reevaluating whether polar bears should be kept in captivity at all, directing resources instead toward wild population monitoring and Arctic conservation. The answer for polar bear welfare may lie in wilderness, not enclosures.
