Seven Worlds, One Planet

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.

Europe, a crowded continent transformed by mankind, where extraordinary animals are found in surprising places.

North America, a land of change where pioneering animals make the most of surprising opportunities.

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