It is easy to think about our direct water use, things like drinking, showering, and cooking. It can be much more difficult to remember that products we interact with on a daily basis use water for production. Think about all the water is takes to grow our food, make our clothes, and build our homes, cars, and computers. The Water Footprint Network has an interactive product gallery where you can easily see how much water is needed to make some the products you use everyday.
