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.
