Polar bears face an existential welfare crisis as sea ice loss accelerates. Their dependence on sea ice for hunting means that climate change directly threatens their ability to meet basic biological needs.
Climate change creates a slow-motion welfare crisis for polar bears. Extending ice-free periods mean longer fasting periods without food. Reduced body condition impairs immune function, reproductive success, and maternal care quality. Starvation deaths are increasing in some populations. Human-wildlife conflict increases as bears seek food near communities. Intra-species aggression rises as competition for limited prey intensifies. Zoos housing polar bears must increasingly grapple with whether captive populations serve conservation or welfare goals. Reducing greenhouse gas emissions is the only long-term solution — all other interventions are palliative.
