Nature Inc - Series 1: Episode 2

Every year we spend billions of dollars on pumping and purifying water for the world’s ever-expanding cities. But why bother building a desalination plant, when a forest will do the same job for a fraction of the price? Nature Inc goes to New York, Ecuador and Jordan to see how the authorities are waking up to the potential: how they are protecting ecosystems, saving a fortune and safeguarding two of our most precious assets: water and biodiversity.
