Polar bears are vulnerable. It means that they are facing a high risk of extinction in the wild. The survival of the polar bears are threatened by the loss of the sea ice from the effects of climate change. The sea ice are used as their platform to hunt seals, rest and breed. By the effects of climate change, polar bears have a shorter amount of time for hunting until the sea ice breaks apart. They rely on their fat stores from the previous summer to survive. This results in many polar bears suffering from malnutrition and others from starvation, especially females with their cubs.
