Nothing shouts northern wilderness more than a magnificent moose, the undisputed king of the forest. But moose don’t start out big and burly; for two twins born into a forest glade, a challenging life lies ahead. PS Funny Stuff inside :)
Few places on earth evoke more mystery and romance than Arabia. This enters the forbidding wilderness and reveals a magical cast of characters. From the snow-white oryx that inspired the myth of the unicorn to the long-legged jerboa leaping ten times its own body length through the star-filled Arabian nights. Horned vipers hunt glow-in-the-dark scorpions, while Bedouin nomads race their camels across the largest sand desert in the world.
No continent experiences seasonal change as extreme as North America. From tornados that roar across the prairies, to Arctic air sweeping through the humid, southern swamps - this is a land where pioneering animals thrive. In winter, lynx prowl the snowy Yukon for snowshoe hares, whilst Florida manatees seek hot springs to escape the freeze. In the creeks of Tennessee, fish build spectacular underwater pyramids to find a mate. Fireflies light up the forests during summer nights, roadrunners cruise the spectacular deserts of Arizona and polar bears leap from rocks to hunt beluga whales.
Oxygen – we all need it, we can't live without it. It's integral to life on this planet. And it's probable that, as you watch this film, you will be breathing in an oxygen atom that was also breathed by Genghis Khan – or by the first ever apes to stand upright on the plains of Africa. The oxygen that we breathe is made from two oxygen atoms joined together – O2. They were first joined more than 3 billion years ago by the earliest blue-green algae to evolve. The oxygen molecule first came from bacteria and was present in the fires that destroyed the dinosaurs and the chemical reactions in all human cells, and as ozone they protect the earth from radiation. Since then, both together and apart, they've had the most extraordinary adventures. Each of the two atoms in an oxygen molecule is virtually indestructible – so they have been first-hand players in some of the most dramatic events in the whole of Earth's history. It's often said that we are breathing the same oxygen that the cavemen did. The life of a single molecule of oxygen is traced on it's astonishing journey spanning millions of years, from its creation, into photosynthesis, through the age of the dinosaurs, early man, and on into today.

David Attenborough takes a breathtaking journey through the vast and diverse continent of Africa as it has never been seen before. (Part 3: Congo) The very heart of Africa is covered in dense tropical rainforest. The animals that live here find the most ingenious ways to carve out their space in a claustrophobic landscape. Danger lurks in every shadow, but some animals thrive here, from honey-stealing chimps to birds with a lineage as old as the dinosaurs, thundering elephants and kick-boxing frogs. Here in the Congo, no matter how tough the competition, you must stand up and fight for yourself and your patch.
