Dear EarthTalk: Isn’t it a waste that we buy water in plastic bottles when it is basically free out of our taps? Even health food stores, which should know better, sell it like crazy. When did Earth’s most abundant and free natural resource become a commercial ‘beverage’? -- A. Jacobs, via e-mail
Bottled water has been a big-selling commercial beverage around the world since the late 1980s. According to the Worldwatch Institute, global bottled water consumption has more than quadrupled since 1990. Today Americans consume over 30 billion liters of water out of some 50 billion (mostly plastic) bottles every year. The Beverage Marketing Association reports that in 2008 bottled water comprised over 28 percent of the U.S. liquid refreshment beverage market. The only bottled drinks Americans consume more of are carbonated sodas like Coke and Pepsi.
