Virtual water is a calculation of the water needed for the production of any product from start to finish. A pound of meat takes five to ten times the amount of virtual water to produce as vegetables. It's like thinking to eat local produce.
I’ve been mindful of the amount of water I use when making a pot of coffee ever since learning that one-third of the tap water used for drinking in North America is actually used to brew our daily cups of joe—and that if each of us avoided wasting just one cupful of coffee a day, we could save enough water over the course of a year to provide two gallons to every one of the more than 1.1 billion people who don’t have access to freshwater at all.
