A severe drought is currently affecting over 4.5% of the continental U.S. These 6 foods could be making it worse. 1. Almonds are extremely water-intensive, using 3.2 gallons to grow each one. 2. Beef is a drain, as cows demand 24 trillion gallons of water to irrigate 56 million acres of pasture. 3. Over 52 gallons of water are used to produce an 8-ounce glass of milk. 4. Beer is made of water, and the industry sold 2.8 billion cases in 2018. 5. Coffee requires 35 gallons of water to grow enough for a single cup. 6. Because chocolate is slow to mature, it can soak up 1,500 gallons of water to make an 8-ounce bar.
