Seven Worlds One Planet

- Season 1

(2019)

The snowy shores and icy waters of Antarctica are home to some of the most amazing and unusual wildlife in the world. However, even here, many species face extinction due to rapid climate change and overhunting.

Asia is the largest and most extreme continent on Earth. The animals here live in the hottest deserts, tallest jungles and highest mountains in the world, but global warming and deforestation threaten many species including the orangutan.

South America - the most species-rich continent on earth. From the volcanoes of the Andes to the world's largest rainforest, animals here must specialise to carve out a niche.

Australia, a land cast adrift at the time of the dinosaurs. Isolated for millions of years, the weird and wonderful animals marooned here are like nowhere else on Earth.

Sir David Attenborough explores the continent of Europe - a crowded continent transformed by mankind. From the rare and elusive wolves to the almost-extinct Iberian lynx, this continent needs protection to ensure a future for its wildlife.

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. In Canada's Yukon, winter can be brutal - up to six feet of snow can fall in a single day. But lynx have found a way to survive where others cannot, pushing farther north than any other cat species on earth. To catch a meal, they must outsmart quicker and more nimble prey, the aptly named snowshoe hair. With no east-west mountain range crossing ...

Africa, home to the greatest wildlife gatherings on earth. But even in this land of plenty, wildlife faces huge challenges.
