In this first episode they travel from July to the December solstice, experiencing spectacular weather and the largest tides on Earth. To show how the Earth's orbit affects our lives, Helen jumps out of an aeroplane and Kate briefly becomes the fastest driver on Earth.
Groundbreaking documentary which follows a Japanese-led team of scientists as they attempt to shed light on the mysterious world of deep sea sharks. Only 50 specimens of the newly discovered 'megamouth' have ever been sighted. Over four years, scientists and film crews voyaged in midget submarines into the depths of Suruga Bay and Sagami Bay to film them. Prehistoric 'living fossil' sharks such as bluntnose sixgill sharks, goblin sharks and frilled sharks also lurk in the bay. As part of the investigation, a sperm whale carcass was placed at the bottom of the bay to attract these sharks, which were then studied and observed from the submersible vessels. Revealing in detail the previously unknown behaviour of deep sea sharks, the film unravels another of the intriguing mysteries of our planet's biodiversity. Narrated by David Attenborough.

When you picture the lowest levels of the food chain, you might imagine herbivores happily munching on lush, living green plants. But this idyllic image leaves out a huge (and slightly less appetizing) source of nourishment: dead stuff. John C. Moore details the "brown food chain," explaining how such unlikely delicacies as pond scum and animal poop contribute enormous amounts of energy to our ecosystems.

From the shelter of our homes, snow looks magical, but it's a harsh reality to many animals. Snow means freezing temperatures, which these animals must endure for many months. Wildlife cameraman Gordon Buchanan meets some of the world's most iconic snow animals across the globe, from the penguins of Antarctica to the bison of Yellowstone and the Arctic fox. Beyond the Arctic Circle in northern Norway, he encounters wolves, lynx, reindeer, polar bears, muskox, and even a woolly bear - the most miraculous, coolest Arctic caterpillar! Buchanan reveals the incredible adaptations and extraordinary strategies these animals use to survive.

David Attenborough narrates a documentary looking at the wildlife of the most stunning mountain range in the world, home to snow leopards, Himalayan wolves and Tibetan bears. Snow leopards stalk their prey among the highest peaks. Concealed by snowfall, the chase is watched by golden eagles circling above. On the harsh plains of the Tibetan plateau live extraordinary bears and square-faced foxes hunting small rodents to survive. In the alpine forests, dancing pheasants have even influenced rival border guards in their ritualistic displays. Valleys carved by glacial waters lead to hillsides covered by paddy fields containing the lifeline to the East, rice. In this world of extremes, the Himalayas reveal not only snow-capped mountains and fascinating animals but also a vital lifeline for humanity.
