Watch Hostile Planet

The frozen poles are home to the planet's ultimate survivalists, including polar bears, penguins and Arctic wolves; their world is changing fast -- breaking apart under their feet -- and their resilience will be tested beyond the extreme.

Deserts are getting even hotter, drier and bigger, yet a host of remarkable animals still survive in the harshest of conditions, including cunning hyenas, pint-sized meerkats and sand-dwelling spiders.

Jungles comprise the most diverse habitats on Earth in which only the most resilient species triumph; the fiercest jungle species include jaguars, caimans, gibbons, orangutans, spectral tarsiers, hummingbirds, and parasites.

An epic bison hunt gets up close and personal.

Dive beneath the surface of Earth's oceans to discover animals as they fight to adapt.

The highest mountains on Earth are home to snow leopards, golden eagles, mountain goats, barnacle goslings and gelada monkeys. But only the toughest can endure the extreme weather, scarce food and limited oxygen on these peaks. Using new technology to showcase never-before-filmed animal behavior, Hostile Planet provides unique access to one of the most extreme environments on the planet.
