From space, Earth looks like a planet overflowing with water. But only about 0.007 percent is fresh and usable, and even that amount is under threat. Whether for drinking, cooking, bathing, washing clothes, or other basic tasks, the average American uses around 80 gallons of water a day—but that’s just a fraction of their total usage. There’s an additional 2,000 gallons “hidden” in what one consumes on a daily basis. Scientists have made that hidden number visible by calculating what is known as a water footprint, and how we cook and eat is a big part of it.
How much do you know about your own water footprint? Take this quiz to find out.
