Wild Polar Bear Welfare and Climate Stress

Polar bears face deteriorating welfare as Arctic sea ice declines, forcing longer fasting periods, increased human conflict, and physiological stress from warming temperatures.

Key Facts

Polar bears depend on sea ice to hunt ringed seals, their primary prey
Arctic sea ice extent has declined by approximately 13% per decade since satellite records began
Longer ice-free periods force bears to fast onshore for extended periods, causing weight loss and stress
Problem bear encounters in communities have increased as bears seek food in human settlements
Churchill, Canada, has become a focal point for human-bear conflict management

Welfare Considerations

Polar bears experiencing extended fasting periods suffer from protein catabolism, reduced immune function, and in severe cases starvation. Cubs born to nutritionally stressed mothers have lower survival rates. Bears attracted to human settlements seeking food face lethal removal. Chronic stress from inadequate prey availability causes physiological changes measurable through stress hormone analysis. Climate change represents the most significant and irreversible driver of polar bear welfare deterioration.

What You Can Do

Support climate action to protect Arctic sea ice as the most important polar bear welfare intervention
Donate to polar bear conservation organisations including Polar Bears International
Support non-lethal bear management in Arctic communities including electric fencing
Avoid polar bear tourism that increases habituation and human-bear conflict
Raise awareness about polar bear welfare as a direct consequence of climate change
