Polar bears face an accelerating welfare crisis as sea ice loss driven by climate change reduces their access to their primary prey, leading to starvation, family disruption, and escalating human conflict.
Starvation is a prolonged and agonizing death for any mammal. Polar bears undergoing the extended fasting forced by sea ice loss experience muscle wasting, organ failure, and weakness that progresses over weeks or months. Cubs that fail to thrive due to underfed mothers die slowly. Successful reproduction is increasingly disrupted - females that invest in pregnancy and denning but cannot find adequate food after emerging represent wasted biological investment and individual suffering. The escalation in human conflict as bears forage in communities leads to bear deaths and individual trauma. Every degree of warming represents more individual bears experiencing more prolonged suffering.
