Forget carbon footprint. Long before the Earth will suffer from a climate catastrophe due to global warming, humanity may perish from another environmental disaster: the diminishing supply of fresh water

(Don’t believe it? Why, humans have been fighting wars over water for centuries)

In collaboration with Fogelson-Lubliner, GOOD Magazine has an eye-opening infographic of “water footprints”, the amount of water an individual uses in the course of a day, as well as ways to save water by making simple changes in your habits. I, for one, am surprised at the amount of water it takes to yield a pound of beef!

As we become more and more aware that we may be using water at an unsustainable pace, the idea of water footprints—the amount of water an individual uses—is becoming more common. Water footprints can be hard to calculate, depending on how far up the chain of production you go, since everything you eat and buy used some water to produce (to feed cows for beef, for example, or to use in the factory that made your cell phone). With GOOD Magazine’s latest Transparency, they give you some examples of how much water is used in some of your daily activities, so that you can begin calculate your footprint and try to reduce your gallons. See the graphic in big.

To help put things in perspective, think about this: your standard trash barrel holds 32 gallons and a mid-sized passenger car—if pumped full of water—has room for a little more than 800 gallons….

So, the difference in the amount of water it takes to produce a pound of chicken and a pound of beef is enough to fill almost two whole cars!!!
