Planet Earth (TV Series)
Season 1 Episode 3 “Fresh Water”
UK broadcast 19 March 2006
US broadcast 15 April 2007
The fresh water programme describes the course taken by rivers and some of the species that take advantage of such a habitat. Only 3% of the world’s water is fresh, yet all life on land is ultimately dependent on it.
Its journey begins as a stream in the mountains, illustrated by Venezuela’s Tepui, where there is a tropical downpour almost every day. It then travels hundreds of kilometres before forming rapids. With the aid of some expansive helicopter photography, one sequence demonstrates the vastness of Angel Falls, the world’s highest free-flowing waterfall. Its waters drop unbroken for nearly 1,000 metres (3,000 feet) and are blown away as a mist before they reach the bottom.
