Think about how cows use water to make milk. First, cows drink water. They also eat food which needs water to grow. Water is also used to wash the cows and the equipment in their barns. Once the cows' milk leaves the dairy farm, it goes to a creamery, where water is used to process the milk and wash out the cartons or bottles. When you consider all that, how much water is needed to produce an eight-ounce glass of milk?
