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.
Steve Backshall visits unexplored parts of the world. This time his team is kayaking in the Arctic - they face perilous sea ice and have a terrifying encounter with a polar bear.

Steve Backshall leads a team of elite explorers - including world leading underwater cave explorer Robbie Schmittner, former Royal Marine Aldo Kane and diving camera operator Katy Fraser - into the wilds of the Yucatan Peninsula in Mexico. Under the vast jungle here is the largest unexplored network of caves in the world, comprising thousands of kilometres of passageways. They are stunningly beautiful but incredibly dangerous - much of the system is under water. First the team must trek through tough, scorpion-infested jungle to camp alongside a giant sinkhole in the jungle floor - a dark gateway to an underworld full of nightmarish creatures.

Planet Earth was inhabited by many wondrous creatures throughout the Permian period. Massive geologic changes finally allowed life to thrive on land and sea, producing voracious saber-toothed carnivores like Gorgonopsid and the terrifying 40-foot shark Helicoprion. But it couldn't last forever...

Spring arrives in the polar regions, and the sun appears after an absence of five months; warmth and life return to these magical ice worlds - the greatest seasonal transformation on our planet is underway. Male Adelie penguins arrive in Antarctica to build their nests - it takes a good property to attract the best mates and the males will stop at nothing to better their rivals! But these early birds face the fiercest storms on the planet. In the Arctic, a polar bear mother is hunting with her cubs. Inland, the frozen rivers start to break up and billions of tons of ice are swept downstream in the greatest of polar spectacles. This melt-water fertilizes the Arctic Ocean, feeding vast shoals of Arctic cod and narwhal. The influx of freshwater accelerates the breakup of the sea-ice - an area of ice the size of Australia will soon vanish from the Arctic. On land, a woolly bear caterpillar emerges from the snow having spent the winter frozen solid. Caterpillars normally become moths within months of hatching, but life is so harsh here that the woolly bear takes 14 years to reach adulthood. Once mature it has only days to find a mate before it dies! Alongside the caterpillars white Arctic wolves race to raise their adorable cubs before the cold returns.

The Lake Erie water snake, once on the brink of extinction, now looks to be rebounding--thanks mainly to the invasive goby fish that's wreaking havoc on the Great Lakes ecosystem. Can scientists studying this environmental anomaly find a healthy ecological balance?

Antarctica is the most remote and pristine wilderness on the planet. , It is a timeless and harsh land like no other. Night here can last three months and in the peak of summer the sun never sets. To understand how life can exist in this continent of snow and icebergs you must spend a year there. You discover that despite being the least habitable place on Earth, life abounds in Antarctica. Megafauna such as humpback whales and orca, massive seals and stately penguins all take the brutal conditions head on and thrive in this year on ice.
