Hostile Planet

Only the toughest animal species can endure the extreme weather, scarce food and limited oxygen available on the Earth’s highest mountains.

In the grasslands, animals endure freezes, fires, floods, and droughts. Bull elephants clash in mating battles. Cheetahs and gazelles engage in a predator-and-prey dance in the Kenyan savanna. Bison battle a blizzard while being pursued by wolves.

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.
