Pacific walruses depend on sea ice for resting, nursing, and avoiding predators, but vanishing Arctic sea ice is forcing them onto dangerous land haulouts in growing numbers.
The welfare impacts of sea ice loss on walruses are severe and escalating. Stampede events cause traumatic deaths, and the chronic stress of overcrowded land haulouts, extended feeding swims, and calf separation represent sustained welfare burdens at population scale. Individual walruses in these conditions experience fear, exhaustion, injury, and nutritional stress. The root cause is climate change, making emissions reduction the most important long-term intervention. In the short term, protecting haulout sites from human disturbance is a critical welfare measure.
