As the land flattens out rivers slow down and lose their destructive power. Now they are carrying heavy loads of sediment that stains their waters brown. Lines of wildebeest are on their march. Each year nearly two million animals migrate across the Serengeti plains in search of fresh green pastures. For these thirsty herds the rivers are not only a vital source of drinking water, but also dangerous obstacles. This is one of the largest concentrations of Nile crocodiles in Africa, giants that grow over five metres long. The planet's indisputable super-river is the Amazon. It carries as much water as the next top-ten biggest rivers combined. Rising in the Peruvian Andes, its main trunk flows eastwards across Brazil. On its way the system drains a third of South America. Eventually, over 4,000 miles from its source, it empties into the Atlantic Ocean. The Amazon transports a billion tonnes of sediment a year, sediment clearly visible at the mixing of the waters where one massive tributary, the Rio Negro, flows into the main river. Its waters are wonderfully rich.
