Everyone has probably heard that you should be mindful of your carbon footprint – you know, what you do and its environmental impact. Well, as I was flipping through a magazine, I read that there’s another footprint to consider!
In the June issue of Discover Magazine, Thomas Kostigen, the author of the article, writes that our water consumption not only includes the actual water consumed from the tap, but also the virtual water that we intake. What does he mean by virtual water? Virtual water encompasses the water used in the production of food and products, like clothing and furniture. When you compare foods, grains and vegetables require less water, which are harvested after a growing season, than their meat-bearing counterparts. Nothing is without a water footprint – even a sheet of paper and that leather bag you carry footprints of three and 6,340 gallons of water. Makes you think twice about what you eat and buy, no?
For more information about water footprints, check out waterfootprint.org, which information about virtual water and the water footprint concepts, as well as a calculator to see just what sort of wet footprint you’re leaving on the planet.
