Remember that beef? Eat less meat. A single hamburger’s water footprint equals a month of showers. Or just switch to chicken—it’s half the guilt. And eat your veggies: a salad uses a tenth of the water a steak does. You’ll also save money and avoid that weird post-burger nap.
Clothing is another shocker. A cotton T-shirt requires 700 gallons of water to grow and make. Wear your jeans twice between washes; you’re not a paramedic. Patagonia has a “Worn Wear” program, but your closet already has a “Don’t Buy New” program. Surprising fact: The fashion industry uses 93 billion cubic meters of water a year—enough to fill 37 million Olympic pools. That’s a lot of swim lanes for celebrities.
