The Telegraph thinks so. And the fact that bottled water generates up to 600 times the CO2 emissions maybe they’re right. The fact that we’re so willing to pay for something that is free is either genius marketing, incredible stupidity, or some combination of the two. That said, since I’m suspect as to the benefits of fluoride and the health impact of chlorine I hedge bets with the bottled water. Sometimes. The World Land Trust has a website for those concerned where you can check carbon offsets based on your lifestyle.
