U.S. bottled water consumption skyrocketed from 1.6 gallons per person annually in 1976 to 30 gallons by the mid-2000s, despite bottled water costing up to 10,000 times more than tap water. The use of these plastics burns millions of barrels of oil producing plastic bottles and releases thousands of tons of CO₂ in transport. Meanwhile, plastic waste in the ocean kills up to one million sea creatures each year.
