BOTTLED WATER ISN'T NECESSARILY CLEANER: According to the San Francisco Chronicle and lawsuits from the Environmental Law Foundation, 40% of bottled water is really just repackaged tap water. Maybe that's a good thing, considering federal standards for tap water are actually higher than those for bottled water.
BOTTLED WATER AND OIL: Supplying Americans with plastic water bottles for one year consumes more than 47 million gallons of oil, according to the Container Recycling Institute. That's enough to take 100,000 cars off the road and 1 billion pounds of carbon dioxide out of the atmosphere. Add in the additional amount of oil it takes to ship the bottles thousands of miles from extraction source to recipient, and your drink of H2O could be categorized with the "Hummers" of the world.
BOTTLED WATER AND BIODEGRADABILITY: Buddha's bones turned to dust a long time ago. But if he had been a bottled water drinker, that plastic would still be laying around. It takes two minutes to drink a bottle of water, but it takes thousands of years for that piece of plastic garbage to go away.
SOLUTION: Buy a water filter and a non-plastic water container of your preferred size. Fill it up in the morning before you go to work or school. Do a quick online search, and you can also find affordable portable water filters for when you are traveling. You'll save yourself and the environment a lot of expense.
