If you drink bottled water, you may be adding to your carbon footprint unwittingly. Production of plastic bottles for those fancy-label H2Os uses 1.5 million barrels of oil per year - enough to fuel 100,000 cars.
Just the transportation of bottled water results in increased carbon emissions from trucking the water to market.
And soon there will be a couple of bottled waters that will have to include the fact that they are nothing more than tap water. Both Aquafina by Pepsico and Dasani by Coca-Cola get their water from public water sources. Those are the sources that flow through pipes into your house, the low-carbon alternative.
Furthermore, bottled water has been linked to an increase in the incidence of cavities amongst young people. Most bottled waters contain flouride levels that are well below standards. Flouridation of municipal water sources has been heralded as the single most successful health achievement since the 1960s. But the desertion of public water sources in favor of bottled water has led to a rise in the rate of cavities that is comparable to pre-1960s levels.
So - save the planet, save your teeth and save your wallet. Next time, turn on the tap to quench your thirst.
