Many people do not realize how much water it takes to get the food they commonly eat.
For example, how much water does it take to make a hamburger?
According to the U.S. Geological Survey (USGS), a quarter-pound hamburger takes about 460 gallons to produce. It says, “Estimates vary a lot due to different conditions of raising cows. The number also varies depending on how far back in the production chain you go. It takes a lot of water to grow grain, forage, and roughage to feed a cow. Water is also needed for drinking supplies as well as for servicing the cow. Per kilogram of product, animal products generally have a larger water footprint than crop products.”
According to the USGS, one pound of bread takes 193 gallons of water to produce, and chicken takes 500 gallons per pound.You can try your guess at how much water it takes to grow/produce items at https://water.usgs.gov/edu/activity-watercontent.html.
