Our Bear Tracker shows current and past sea ice levels on Hudson Bay, along with the rough locations of polar bears. Using this tool, you can see how the bears follow the ice, which they rely on for hunting seals. Without ice, polar bears can't survive. This video shows sea ice losses in the Arctic over the past 30 years.
