Ever find yourself going through a dozen 10 oz. water bottles in a day? Think about all the energy it took to produce the bottles and transport them to you. Instead of wasting your money and damaging our environment with bottled water, try carrying your own reusable container! Plus, bottled water has almost no regulation (could be less clean than NYC tap) and is most often municipal tap water. Check the bottle on a Poland Springs bottle next time your at the store and notice all the "mountain spring" sounding city sources of the water.
