The world’s freshwater is in short supply thanks in part to a ballooning global population that uses thousands of liters of water everyday to produce foodstuffs from oil and vegetables to meat, dairy and alcohol. Now researchers have discovered new evidence that a healthy diet, like those followed by pescatarians and vegetarians, also uses significantly less water.
“It is a win-win situation,” said Davy Vanham, a water management researcher at the Joint Research Center of the European Commission in Ispra, Italy, who led the new work.
