A look at how the planet's limited fresh water is distributed around the globe thanks to storms, and how animals manage in the driest habitats on Earth.
Behind the scenes with the Perfect Planet film crews as they document epic wildlife stories.
Michael Mosley finds out why fizzy drinks make you eat more. GP Dr Zoe Williams investigates whether caffeine boosts physical performance. Geneticist Dr Giles Yeo discovers what men can do about baldness. Surgeon Gabriel Weston looks into the new artificial pancreas that could transform life for diabetics. And Dr Alain Gregoire gives the psychiatrist's guide to obsessive compulsive disorder.
Alexander Armstrong heads to the south of the country, which has epic scenery. He leaves the boiling mud and lava flows of the volcanic island below as he ascends to the breathtaking, freezing roof of Europe's biggest glacier.
The ocean is where life first began, and where it first experimented with the mating game. All the creatures living here face the same challenge - how to find a partner in the largest and least-populated habitat on earth. To solve that challenge, marine animals have developed some of the most ingenious breeding strategies of all. The waters off Hawaii are witness to the largest courtship battles on the planet.
Incredible facts and myths about the animal kingdom are put to the test. Is it true that a giant squid can sink a ship?

Grasslands cover one quarter of all land and support the vast gatherings of wildlife, but to survive here animals must endure the most hostile seasonal changes on the planet. From Asia's bizarre-looking saiga antelope, to the giant anteaters of Brazil, grassland animals have adapted in extraordinary ways to cope with these extremes.
Eastern China is one of the most densely populated regions on the planet, but even there, humans provide the necessary space for the animals that inhabit it. Some of the rarest animal species will find a home in one of the four new national parks.
Ben journeys to one of Britain's furthest outposts, the Shetland Islands, to meet Helen and Jason - a couple just a few years into their new life on the edge of the weather-beaten island of Yell.
Simon looks at his journeys through some of the world's most spectacular and unspoilt wildernesses and reflects on the huge challenges we face in trying to protect them.
The important and ultimately hopeful story of the future of the greatest wildlife continent on earth.
As winter returns to the Arctic, the Alaskans prepare to survive the coming months. For the Hailstones, time is running out to hunt big game animals.
To survive the worsening conditions in the Arctic, Alaskans must finish the tasks that will keep them ahead of winter's wrath. Glenn Villeneuve hunts caribou to keep his family fed.
