Plastic water bottles produced for U.S. consumption take 1.5 million barrels of oil per year, according to a 2007 resolution passed by the U.S. Conference of Mayors. That much energy could power 250,000 homes or fuel 100,000 cars for a year, according to the resolution.
Cornell University professor and environmentalist Doug James said the irony of bottled water is that it's marketed as clean and healthy when its production contributes to unnecessary environmental degradation.
"Fiji water, for example," he said. "A one-liter bottle is taken out of the aquifer of this little island, and shipped all the way across the world, producing like half a pound of greenhouse gases so you can have this one-liter bottle of water."
The article also mentioned that not everyone recycles their empty bottles, so the landfills are quickly filling with them. For the record, I use a Britta filter to re-fill water bottles. So while I buy bottled water on occasion, I can re-use that same bottle 10 to 20 times before I replace it.
