2. Earth and environment

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.

The majority of the world's population live alongside rivers. For these peoples, the waters bring times of plenty and times of great danger and so these communities have to adapt to the ebb and flow of their environment.

The world's rainforests are brimming with life. They are environments of plenty where a successful community needs more than the hunt for resources to keep it together.

Some people understand the seas in a way modern science cannot comprehend. Yet this understanding has stemmed from extreme isolation and the ability of communities to exist on even the smallest land masses and to harvest bounty that can be seen below the waves or beyond the horizon.

Many people have a deeply spiritual connection with high places, be they European mountain climbers, yak herders or descendants of the Inca. But these are also tough places where you have to fight for survival.

Presented by Professor Iain Stewart we've seen how the fate of past civilisations have been shaped by the planet's natural forces. However, in the final episode of this spellbinding series, the good professor says our relationship with the planet today is a different one.

Gripping stories of birth, death, struggle and renewal are told in this collection of stunning footage from the Great Migrations series, set to an original score in a moving visual concert.

It's obvious, but true that the availability of water dominates life in the desert. Vital to the Kababish are the huge areas of north Sudanese desert that provide bountiful grazing paradise after good rains. This is the fabled gizzu. It may be a 1500km round trip away and involve the crossing of a vast expanse of sandy desert, but a good three months spent here with your camels ensures wealth, status and marriage.

Jungles cover roughly three percent of our planet, yet contain a staggering 50 per cent of the world's species. Located around the warm, sunny equatorial zone, complete with constant daylight, they are the most productive habitats on earth. Beautiful floating aerial shots introduce the world's most spectacular forest vistas and high-definition cameras enable unprecedented views of the species that live on the dark jungle floor. Narrated by David Attenborough.

For the first time ever, Earth's incredible story is told in a single, seamless journey from its violent birth 4.5 billion years ago, through ice-ages and the dinosaurs' reign to the first humans.

As Australia and New Zealand have recently witnessed, the Earth has immense power. Yet that influence is rarely mentioned in history books. Scottish Professor, Iain Stewart, is dead keen to change that in this enthralling series. Tonight it's Fire - deadly, yet a driving force behind human progress.

Life on the plains and grasslands of the world is about movement, freedom and livestock. The Nyangatom of southern Ethiopia have fought and won a rangeland for themselves, but they and their herds of cattle and goats are totally reliant on gigantic wells. At the height of the dry season a huge collective well is dug down on the dry bed of the Kibish River. These hand dug wells can be 30m wide and 30m deep and are designed as pits as the sand walls are prone to collapse. Dozens of people are killed by collapsing wells each year.
