The Living Planet
The Living Planet: A Portrait of the Earth is a BBC nature documentary series written and presented by David Attenborough, looking at the ways in which living organisms, including humans,
adapt to their surroundings. The series consists of twelve episodes which explain how the Earth works and how living organisms survive and thrive in different environments.
Episode 08 - Sweet Fresh Water. This episode focuses on freshwater habitats. Only 3% of the world's water is fresh, and 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. They accumulate sand and gravel en route, and this erodes all but the hardest surrounding rocks.
The Yellow River of China carries the most sediment of any river. By the time it has settled down and fallen
over its last cascade, the water becomes tranquil and rich with nutrients from its banks.
