Polar bears are among the most challenging species to maintain humanely in captivity. Their extreme spatial needs and specialized predatory behaviors are difficult to replicate in zoo settings.
Polar bears represent a defining case study in zoo welfare limitations. Their enormous ranging behavior, specialized predatory ecology, and sensitivity to environmental complexity make genuine welfare satisfaction in captivity exceptionally difficult. Stereotypic pacing — a well-documented indicator of psychological distress — is near-universal in captive polar bears housed in traditional exhibits. Enrichment programs can reduce but not eliminate stereotypies, and the scientific consensus is shifting toward the view that polar bears should not be kept in captivity unless for genuine conservation purposes.
