Each day an estimated 60 million plastic water bottles are thrown away. Most are not recycled. The Pacific Institute has estimated 20 million barrels of oil are used each year to make the plastic for water bottles.

Economically, it makes sense to stop buying bottled water as well. The Arizona Daily Star recently examined the cost difference between bottled water and water from the city's municipal supply. A half-liter of Pepsi's Aquafina at a Tucson convenience store costs $1.39. The bottle contains purified water from the Tucson water supply. From the tap, you can pour over 6.4 gallons for a penny. That makes the bottled stuff about 7,000 times more expensive, even though Aquafina is using the same water source.
