Climate change has a significant impact on polar bears. The warming of the Arctic region leads to a reduction in sea ice, which is essential for polar bears to hunt for seals, their primary prey. With less sea ice, polar bears have to travel longer distances to find food, leading to decreased body condition and reproductive rates. Additionally, the loss of sea ice habitat increases the potential for human-polar bear conflicts as bears come onto land in search of food. Overall, climate change poses a serious threat to the survival of polar bears.
