Frozen Planet II

Our planet is powered by the oceans, entangled in plants, and home to animals of every colour, shape and size. But in its last true wilderness, our planet is white . . . welcome to our frozen planet.

Each year, a quarter of our planet is frozen solid, so let's journey to these ice kingdoms:

Dive under the ice ceiling and learn to swim with the seal pups, take to the skies with frozen flamingos, and settle in for a snooze with a windy walrus.

Watch orcas sneak up on bowhead whales while they're relaxing in the spa, meet a Greenland shark that is easily 250 years old, and witness the polar bears who are finding their food closer and closer to humans.
