Going down into these narrow flooded passageways is not for the faint-hearted but, with only an estimated one percent of the caves explored, it is an opportunity for the team to write themselves into cave diving history, by pushing further in than anyone has before. This is a challenge that tests even the most accomplished cave divers. Steve must face the terrors of being lost in an underwater silt cloud in a cave. But there is a bigger issue at stake. All life in the Yucatan depends on the fresh water in this network of caves, but it's being contaminated by human development. With every metre the team maps, it adds to the knowledge of the system, which, in turns, helps protect it for future generations.

In episode three, Fortey looks at the Ice Age. 2.8 million years ago - triggered by slight changes in the Earth's orbit around the sun and shifts in its ocean currents - the world began to cool. Within a few thousand years much of the planet was shrouded in a dense cloak of ice that would come and go until only 10,000 years ago. We call this age of ice - the Pleistocene Age - and it transformed the hierarchy of nature. This is the story of how a few specialist species that evolved to live in the biting cold survived into the present day.

Discover a land of hauntingly beautiful coasts, magical forests, and volcanic and arctic extremes - and the lynx, orcas, puffins and wolves who call this frozen kingdom home. Chapter 1: Life on the Edge Wild and unpredictable, the Scandinavian coast is a place of haunting beauty and dangerous extremes - a journey from storm-swept islands crowded with seal pups to 3,000ft deep fjords where sea eagles fly and base jumpers parachute from the edge. In the far north, tropical currents and Arctic seas collide, creating riches - billions of herring tracked by orcas and humpback whales - while providing a home to thousands of seabirds, including the feisty puffin. Chapter 2: Heartlands Great forests form the heart of Scandinavia, stretching towards the Arctic and cutting through with a labyrinth of waterways. Incredible creatures like lynxes, wolves, bears and reindeer must survive the ever-changing seasons - from the chilling grip of winter to the warm riches of summer. Here, all life is deeply interconnected through surprising and ancient partnerships, creating a balance that has evolved over millennia. Chapter 3: Ice and Fire Scandinavia's northern extremes have been shaped by ice and fire, but it's the sun that reigns over these frozen kingdoms. Here, musk oxen, polar bears and arctic foxes must endure the long, dark polar night, but in spring, the sun's return ignites a dramatic transformation in the landscape and heralds the return of thousands of migrant visitors. Under the midnight sun, the north bursts into a sleepless rush of life and opportunity, a race against time to raise a family, but for some, it's the summer heat which brings the greatest dangers before the first frost and winter's welcome return.

The ways in which wild animals have adapted to survive in human population centres, from cobras in India hunting in houses, to macaques in Bali stealing mobile phones to barter with temple staff in return for food. Rhinos walk through the streets of Sauraha, Nepal, while in Australia, tawny frogmouths find streetlights useful in catching prey, but have to avoid being eaten by household cats.

The undercover cameras reveal how animals often get up to mischief among themselves - and some are downright criminal. A colony of adelie penguins hunker down to avoid a storm, unaware one of them is a thief out to steal the stones that make up their nests, and Spy Tropicbird witnesses an aerial attack by aggressive frigate birds who attempt to steal his fish. A boisterous elephant has a temper tantrum in the mud near the waterhole, chimpanzees have extra-marital affairs and lemurs get high by sniffing toxic millipedes.
