Title: Invasion of the Killer Whales

A shift of power is taking place at the top of the world. The Arctic is undergoing a dramatic change, and with this change one iconic Arctic hunter may soon have to give way to another as solid ice turns to open sea. 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.
