Description
Polar bears spend most of their lives on the sea ice of the Arctic Ocean. They are on the decline and there is a high risk of future extinction due to climate change. Because polar bears are at the top of the food chain, they have an important role in the overall health of the marine environment. Polar bears depend on sea ice for their survival and are directly impacted by melting ice due to climate change. Every year, as the summer sea ice decreases in size, bears must move greater distances.
