Climate change significantly impacts polar bears by reducing sea ice, their primary habitat. As Arctic temperatures rise, sea ice melts earlier and forms later each year, limiting the time polar bears have to hunt seals, their main food source. This leads to **malnutrition**, decreased body condition, and lower cub survival rates. Polar bears are forced to travel greater distances or move inland, increasing the risk of **human-wildlife conflict**. Additionally, shrinking ice disrupts mating and denning sites, threatening population stability. Without sufficient ice, polar bears face a high risk of **extinction** as their environment continues to deteriorate.
