Watch Jeremy Wade's Mighty Rivers (2/6) live on the web
Biologist, extreme angler and naturalist Jeremy Wade heads to the Amazon. Together with its tributaries, it contains an incredible 20 per cent of Earth's fresh water, and the immense forests it sustains generate a quarter of the oxygen needed for life on the planet.
Disgorging more water than the next nine biggest rivers combined, this waterway is indeed a mighty affair.
By tracing the epic migration of the dorado catfish, Jeremy discovers the issues putting this great river at risk - from leaking pipelines to giant dams.
However, he also discovers tales of surprising hope.
