Water is necessary for all life on Earth. It’s also necessary to produce the goods and products we consume. Just how much water goes into making your hamburger or the jeans you’re wearing? It’s called a "water footprint" and as global water supplies dwindle, some are trying to raise awareness about the water cost of our daily consumption. Host Bruce Gellerman talks with Derk Kuiper, executive director of the Water Footprint Network. He also speaks with Michael Kobori of Levi-Strauss to find out what his company is doing to curb its water use.
