In throwing out millions of tons of food, we also waste uncounted millions of gallons of water that was used to plant, grow, sustain, or otherwise produce it.
Fruit and vegetables are among the most water-laden food products, simply because they contain more water. But meat products are the heaviest water users, simply because the animals drink a lot of water—and more importantly, because so much water is needed for the grain that becomes their feed! It takes about 8 to 10 times more water to produce meat than grain.
All told, if the 1.3 billion tons of food wasted worldwide each year, estimates place the water “in” that amount to be 45 trillion gallons—or 24 percent of all water used for agriculture. And remember that 70% of the world’s freshwater is used for agriculture.
