Thunderous three-ton elephant seals face off for control of the beach, orcas launch from the icy water, and Adéle penguins turn to a life of crime to build their nest — these are a few of the stories that unfold at the harsh, frozen ends of our planet.
Four years in the making, Discovery Channel's breathtaking new seven-part series, Frozen Planet premieres this Sunday, March 18 at 8 p.m.
The Arctic region hosts a thriving wildlife habitat, the largest gathering of seabirds on the planet, and an ocean teeming with fish, but it's threatened by global warming and gas and oil drilling. Invite your friends to get involved and help the Sierra Club continue to protect one of the Earth's remaining wild places.
