Even in areas where tap water is safe to drink, demand for bottled water is increasing--producing unnecessary garbage and consuming vast quantities of energy. Although in the industrial world bottled water is often no healthier than tap water, it can cost up to 10,000 times more.

Making bottles to meet Americans' demand for bottled water requires more than 1.5 million barrels of oil annually, enough to fuel some 100,000 U.S. cars for a year.

Nearly a quarter of all bottled water crosses national borders to reach consumers.
