The exploration of the Mariana Trench in the 1950s helped form geologists' theory of plate tectonics.
In the depths of our seas lives a monster with nine brains, three hearts, eight tentacles and it's one of the smartest beings on the planet. If that's not enough, the octopus has a boneless body, two enormous eyes that take up a quarter of its weight, and its brain and intestines exist in a single pouch. It's also a carnivorous predator that can change shape and colour at will, walk on land and sea, and even cross through fire.
Every step we take, we walk over a fascinating world beneath our feet. What's there is not only a time machine of geologic history; it's a catalogue of multiple histories that tell the story of us and of our planet. Using the visual of a depth chart as a timeline of what has been buried and burrowed through over years, we'll pick the most engaging and unexpected stories across the world that cover examples of archaeology, technological achievement, natural history, anthropology, botany and geography in addition to geology.
After The Great Rift: Africa's Wild Heart we take a look behind the scenes where filming sleeping chimpanzees in the forests of Kibale National Park in Uganda provides some serious challenges for the crew. The chimps nest high up in the canopy and the crew have to hoist themselves and the unique Starlight HD camera up into the branches. They also have painful ant bites and a potential elephant stampede to contend with.
Right now, conservation is going through a major rethink and reassessment of what is the right way forward, bearing in mind the expanding human population. This film opens with dramatic footage of humpback whales - a success story for conservation. The Save the Panda, Save the Whale and Save the Rainforest campaigns are still very familiar, too, but have we got anywhere? Narrated by Simon Poland. Narrated by Simon Poland.
At the conclusion of The Great Rift: Water take a look behind the scenes. Cameraman Gavin Newman has spent several years developing a remote underwater camera which he calls 'Nemo'. He is about to send it on its maiden voyage on a descent into the cracks in the floor of the Southern Red Sea where no human eyes have seen before. However, when a group of Whale Sharks are sighted near the surface it calls for a more manual approach.
What is wilderness, and how much is left? Russell Mittermeier of Conservation International assures us that, by his definition, wilderness still covers 40 percent of the planet. But is there enough to provide landscapes for animals such as elephants? How much wilderness do we need, and how fast is it disappearing? Narrated by Simon Poland.
Madagascar is an island of extremes. While the east is cloaked in soaking rainforest, the west and south is almost a desert. This is a scorching landscape where it might not rain for nine months of the year, and some years not at all. To live here, you have to be a specialist.
Go behind the scenes of the magnificent series, Great Rift. The team head down into the volcanic crater of Mount Suswa in Kenya where they hope to film a troop of very unusual baboons.
The sixth extinction phase - are we really at such a crisis point? As executive secretary of the United Nations Group on Biological Diversity Ahmed Djoghlaf explains the rate of extinctions, the head of IUCN argues that we have no idea how many species there really are. Narrated by Simon Poland.
Travel deep into Madagascar's most luxuriant landscape; the rainforests that cloak the island's eastern mountains. Remote and mysterious, this little-known region of towering peaks and precipitous escarpments is home to over half of all Madagascar's unique species.
The debate over whether global warming is happening is all but over. Even many sceptics concede that the planet is getting warmer and humans are largely to blame. But there are still many unanswered questions.
The final episode of Human Planet looks at the environment which has been made by humans for humans. Cities are our greatest success story and now over half the world's population lives in the urban jungle. They are built to keep untamed nature out, but nature cannot be pushed away. From bed bugs sucking our blood at night, to rats in our restaurants, gangs of monkey muggers and rutting elks in downtown USA, many animals have adapted to living in a world of bricks and steel.
David Attenborough tells the story of one of the most intriguing wild places on earth: Madagascar, a huge island of dramatic landscapes where the wildlife is strange and unique; some of it filmed for the very first time.
