Tropical forests help to generate vast amounts of rainfall each year, adding weight to arguments for protecting them as water and climate pressures increase, say researchers. A new study led by the University of Leeds has put a monetary value on one of forests' least recognized services as a source of rainfall to surrounding regions, finding that each hectare generates 2.4 million liters of rain each year—enough to fill an Olympic-sized swimming pool.
