Bottled Water Boom is Hurting the World’s Environment

"...around the world, factories are using more than 18 million barrels of oil and up to 130 billion gallons of fresh water" and that's just to make the bottles, "Another 41 billion gallons of water is then used to fill them." So why are we using more water to make the bottles then the actual amount of water being put into the bottles? This sounds incredibly wasteful.
