At the heart of the US-Canada border sit The Great Lakes - the world's largest freshwater ecosystem, containing as much as one fifth of the planet's supply. Chapter 1: Source to Sea The water's journey from source to sea spans half a continent - 2,000 miles - and takes more than three centuries to complete. This first of three documentaries charts the feature and its surrounding flora and fauna, showing how beavers, wolves, loons, moose help shape this incredibly vast watershed. Chapter 2: The Big Freeze s winter descends on The Great Lakes, life must contend with the return of the ice that carved this immense watershed thousands of year ago. A polar vortex paralyses fish and ducks and attracts hundreds of bald eagles. Wolves hunt deer trapped by ice, but are manipulated by ravens. Chapter 3: Marvels and Mysteries The spring thaw in America's Great Lakes creates ice tsunamis. Photosynthetic salamanders, fishing wolves, deep-diving moose, baby rattlesnakes and colourful fish hunting mid-air all illustrate unique adaptations to to the warmer, brighter season.

A captivating world of creepy crawlies exists all around us. And they are the biggest group of animals in the world, outnumbering humans 200 million to one. Thanks to millions of years of evolution, these invertebrates not only survive in almost every landscape known to man, but also thrive by means of fascinating, and sometimes bizarre adaptations. There's the Bombardier beetle that squirts a boiling hot liquid from its anus, the Assassin bug that turns its victims into soup, and the Parasitic wasp that lays her eggs inside her victims, until her young are ready to eat their way out. We end off with the biggest bugs on the planet: the Atlas moth with a wingspan of over 20 centimetres, the Hercules beetle that can carry 850 times its own weight, and the Giant centipede - big enough to catch flying bats from midair!

The documentary series reveals the extraordinary riches and wonders of the Polar Regions that have kept people visiting them for thousands of years. Today, their survival relies on a combination of ancient wisdom and cutting-edge science. Most Arctic people live in Siberia, either in cities like Norilsk - the coldest city on earth - or out on the tundra, where tribes like the Dogan survive by herding reindeer, using them to drag their homes behind them. On the coast, traditional people still hunt walrus from open boats - it is dangerous work, but one big walrus will feed a family for weeks. Settlers are drawn to the Arctic by its abundant minerals; the Danish Armed Forces maintain their claim to Greenland's mineral wealth with an epic dog sled patrol, covering 2,000 miles through the winter. Above, the spectacular northern lights can disrupt power supplies so scientists monitor it constantly, firing rockets into it to release a cloud of glowing smoke 100 kilometres high. In contrast, Antarctica is so remote and cold that it was only a century ago that the first people explored the continent. Captain Scott's hut still stands as a memorial to these men. Science is now the only significant human activity allowed; robot submarines are sent deep beneath the ice in search of new life-forms, which may also be found in a labyrinth of ice caves high up on an active volcano. Above, colossal balloons are launched into the purest air on earth to detect cosmic rays. At the South Pole there is a research base designed to withstand the world's most extreme winters. Cut off from the outside world for six months, the base is totally self-sufficient, even boasting a greenhouse.

The team has come to the very deepest part of the jungle, where streams contain the richest life, as well as danger, from four-metre caiman and the electric eel - a fish with a 600 volt shock.

Attenborough describes the course the Amazon, starting high up in the Andes of Peru, whose streams flow into the great river. Young rivers are by nature vigorous and dangerous: they flow fast and form rapids, thick with mud and sediment.
