The Trouble with Bottled Water 1. What’s in the Bottles One problem has to do with what’s in the bottles themselves. The Earth Policy Institute reports that 1.5 million barrels of oil per year‚ which is enough to fuel 100‚000 cars for that same year‚ are required to satisfy Americans’ demand for bottled water. That’s because PET‚ or polyethylene terephthalate‚ the plastic used in water bottles‚ is derived from crude oil. And‚ according to the Earth Policy Institute article "Bottled Water:

Tap Water vs. Bottled Water "The U.S. public goes through about 50 billion water bottles a year‚ and most of those plastic bottles are not recycled" (Karlstrom‚ Solvie‚ and Christine Dell’Amore). Bottled water is harming our environment in many ways. Small things such as transporting these bottles set off fossil fuels which pollutes the air. This could have a huge impact on our environment in the long run. Tap water is more efficient and healthier for our environment‚ instead of bottled water. Bottled
