For several decades, geoscientists have been observing that the Earth is changing rapidly due to human intervention. This action has such a great impact on the biological, geological and atmospheric processes of the Earth that some scientists speak of the dawn of a new epoch: the Age of Man or the Anthropocene.

Take A Spectacular Journey.  It Starts Right Here...  Arabia: Sand, Sea & Sky  Take a stunning tour of Arabia's natural world- a land of vivid contrast and splendor. Your journey begins in the magnificent coral reefs of the Red Sea where barracuda, giant mantra rays, and sharks comb the fertile waters. Then, high in the cliffs of the great mountain barrier, you will be fascinated by the complex social behavior of a troop of baboons. As you descend into the foothills, thousands of migrating birds converge, including the flamboyant Abyssinian Roller which will dazzle you with its brilliant feathers and swooping aerobatic dives. Finally, travel by camel across the immense sculptured desert, as the Bedouins have for more than thirty-five hundred years on an expedition you will never forget in ARABIA: SAND, SEA, & SKY.

In a remote corner of Antarctica, a group of killer whales capture their prey in the most extraordinary fashion. Swimming together, they create waves so powerful and accurate, they can wash a seal right off a piece of floating ice—some of the most sophisticated behavior in the animal kingdom. The hunting technique of pack-ice killer whales has intrigued scientists for decades, and there is still so much unknown about the species. Each scientist on the expedition hopes to discover new truths about these whales.

Every year, thousands of Antarctica's emperor penguins make an astonishing journey to breed their young. They walk, marching day and night in single file 70 miles into the darkest, driest and coldest continent on Earth.  This amazing, true-life tale is touched with humour and alive with thrills. Breathtaking photography captures the transcendent beauty and staggering drama of devoted parent penguins who, in the fierce polar winter, take turns guarding their egg and trekking to the ocean in search of food. Predators hunt them, storms lash them. But the safety of their adorable chicks makes it all worthwhile. So follow the leader... to adventure!!

Presenter and comic Jacob Burley hosts Bear Hunt; a stand-up show in which he explores the existence and extinction of the brown bear in the British Isles.

"Giraffes: The Forgotten Giants" delves into the reasons behind the "silent" extinction of giraffes worldwide, and introduces us to the scientists who are gathering new information that may stave off their decline.

During the last forty years, the photographer Sebastião Salgado has been travelling through the continents, in the footsteps of an ever-changing humanity. He has witnessed the major events of our recent history: international conflicts, starvations and exodus… He is now embarking on the discovery of pristine territories, of the wild fauna and flora, of grandiose landscapes: a huge photographic project which is a tribute to the planet's beauty. Salgado's life and work are revealed to us by his son, Juliano, who went with him during his last journeys, and by Wim Wenders, a photographer himself.
