Polar bears are challenging animals to maintain in captivity due to their vast wild range and specialized ecology. Modern zoo practice is transforming how institutions manage these iconic animals.
Polar bear welfare in captivity requires confronting the fundamental challenge of a species adapted to vast, dynamic, ice-dominated environments living in inherently limited zoo spaces. The evidence for compromised welfare in traditional polar bear exhibits is overwhelming: high rates of stereotypic pacing, often amounting to hours of repetitive locomotion daily, indicate chronic frustration. Modern welfare science approaches this challenge through environmental complexity — varied substrate, water features, foraging opportunities that require problem-solving, frozen food enrichments mimicking ice hunting, and social housing where appropriate. Behavioral welfare assessments using validated ethograms enable systematic monitoring. Some institutions have concluded that polar bear welfare cannot be adequately maintained in captivity and have ended their programs while supporting Arctic conservation — a position endorsed by some zoo ethics frameworks.
