According to the United Nations, which recognizes March 22 as World Water Day, we drink up to a gallon (4 liters) of water each day. More importantly, the food we eat uses even more water. For example, take 2.2 pounds of beef (1 kilo). You need nearly 4,000 gallons (15,000 liters) to produce it. Check out the UN site and share the stas with a friend.
