What Is Your "Water Footprint"?
Do you know how much water it takes to produce your food?
Fresh water is a dwindling resource-and agriculture uses 70 percent of the world's supply. Be conscious of your foods' "water footprint" (how much water it takes to grow, raise or manufacture). Celery is 95 percent water, yet has a water footprint of only 6.5 gallons per pound. Compare that to chicken, which demands 468.3 gallons per pound. Learn more about your water footprint (from what you wear to your pet's water pawprint) and get simple water-savings tips with The Green Blue Book (Rodale, March 2010).
