"I think what really comes out is that goods and services have quite a bit of embodied water
in them, so the industry that is providing the final product does not realize how much water they're actually using in the products they're selling," said Chris Hendrickson, a civil and environmental engineering researcher at Carnegie Mellon.
Every input is measured, from the water taken to raise an animal or crop (known as embodied water
), to gases generated tilling the soil, sowing and harvesting crops, making fertilisers and pesticides, harvesting and transporting the food to be cleaned, packed or otherwise processed, and then transported again to the store and home for use.
