Seven Worlds, One Planet

Icy Antarctica is a land of survivors enduring the most hostile conditions on Earth.

Asia is the largest of all continents; in the frozen north, walrus congregate in extraordinary numbers, bears gather inside volcanoes and yeti-like monkeys fight in the remote forests of China; in the tropical south, the last few Sumatran rhino roam.

The most species-rich continent on Earth; in the Andes, pumas hunt guanaco while rarely seen bears search for mini avocados; in the Amazon, poison dart frogs care for their babies, colorful macaws eat clay and birds make death-defying flights.

A land cast adrift at the time of the dinosaurs; kangaroos and wombats brave snowstorms and gum tree forests are filled with never-before-seen predators.

High above the city of Gibraltar, Barbary macaques, Europe's only non-human primates, live lives full of kidnappings and high drama; in the cemeteries of Vienna Grave Robbing European hamsters do battle with each other for food.

More than any other continent, North America is defined by extreme weather and seasonal change; for animals that live here this poses great challenges, but for those with a pioneering spirit it can also offer great rewards.
