A shift of power is taking place at the top of the world. The polar bear, once king of the North, needs ice to stalk its prey. Killer whales, or orca, on the other hand, are unable to hunt in an ocean locked in ice. As Arctic ice increasingly disappears, the tables have turned. Polar bears are struggling to survive while the now open ocean provides bountiful new hunting grounds for the whales.
