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.
Visits the world's deepest valley: the Kali Gandaki river in the Himalayas. Its temperatures range from those of the tropics in its lower reaches to that of the poles higher up. It therefore shows how creatures become adapted to living in certain environments.

Describes the inhospitable habitats of snow and ice. Mount Rainier in America is an example of such a place: there is no vegetation, therefore no herbivores and thus no carnivores. However, beneath its frosty surface, algae grow and some insects, such as ladybirds visit the slopes. Africa’s mountains are permanently snow-covered, and beneath peaks such as Kilimanjaro and Mount Kenya, there are communities of plants and animals.

Begins in northern Norway, 500 kilometres north of the Arctic Circle. Here, there is only just enough light for the pine trees to survive, but it is extremely cold during the winter. Pine cone seeds provide one of the few foods available at this time of year, and large herbivores such as the moose must also rely on their fat reserves.
1984 • Nature
Details coastal environments and the effect of tides, of which the highest can be found in the Bay of Fundy in North America. In places, erosion is causing the land to retreat, while in others — such as the tropics — the expansion of mangroves causes it to advance.

Across our planet, there are a handful of places that truly astonish, like Mount Everest, the Grand Canyon and Victoria Falls. These wonders seem to have little in common other than - literally - taking your breath away. But they share one other thing: they pose extraordinary challenges for their inhabitants. The second of two documentaries profiling some of the world's most expansive - and inhospitable - landscapes, and the people who live there. A fisherman in Zambia faces off against crocodiles and risks being swept to his death as he tries to make a living above the imposing Victoria Falls, and in the Amazon, a giant fish offers salvation to a hungry family that calls the river home. A boy's future hangs on the outcome of a single horse race in the vast grasslands of the Steppe, and in a European salt marsh, a young man duels with a savage bull in a centuries-old battle of wills.
We reveal the weird and wonderful stories of some of the natural world's incredible single parents: their devotion, dedication and often jaw-dropping endeavour in order to see their babies through to adulthood. From the slow loris covering her baby in toxic saliva to the Weddell seal putting her pup through winter boot camp, a weedy sea dragon cleverly camouflaging his eggs against his body and the female giant Pacific octopus sacrificing herself for her brood - we see how these parents are prepared to go the extra mile to arm the next generation with what they need to survive.
Under the waves and tropical sun, each of Hawaii’s volcanic islands host a unique ocean landscape teeming with biodiversity. But one predator reigns supreme – the shark. With 40 species of shark calling these warm waters home, scientists are seeing new animal behavior around every corner. Whitetip reef sharks “sleep” in tight volcanic tunnels. In the deep water, everything is on the menu for the hunting Tiger shark, from birds to Humpback whales. Hopping from island to island, uncover surprising moments of cooperation, rarely seen hunting tactics and striking insights into these predators of the world’s paradise.
Some animals have an extraordinary ability to find their way. The dung beetle, an insect revered by ancient Egyptians, uses the sun, the moon and even the Milky Way to move its prized ball of dung in the right direction. Pigeons are often considered feeble birdbrains, but they have incredible memories that can recall several complex travel routes with amazing accuracy and they even use man-made roads and hedgerows to find the quickest way home.
The incredible reef life and the birds, lizards and reptiles who cope with the lava rock islands of the Galapagos make this remote series of islands a unique natural habitat. The Panama and Humboldt currents regulate the seasons and the rhythm of life onshore and off.
