Almonds Are Sucking California Dry

California supplies 80% of the world’s almonds, now producing 2.1 billion pounds a year—three times more than it did just 14 years ago. But there’s a hidden cost. Each individual nut requires 1.1 gallons of water. New groves of almond trees are still being added—despite years of drought, which we all know is likely to continue.
