Baffin Island, Canada is located within the Arctic Circle. The polar bear is a marine mammal and one of the most representative animals that is threatened with extinction due to global climate change. Polar bears rely more on the extreme cold weather of the Arctic than other animals, as they cannot rest or hunt without sufficient sea ice. Before the age of two, the cubs have almost no independent hunting ability and rely entirely on their mother. Raising cubs is a severe challenge for mother bears.
