It’s important to stay hydrated, so what better way than to have a filled reusable water bottle at easy access all the time?  It’s especially useful in New York City, where the tap water is drinkable.  If you use your own water bottle, you won’t have to contribute another plastic water bottle to the world.  Don’t be deceived by those little 8-ounce bottles — there’s a lot of energy wasted on those!  For example: in 2006, 17 million barrels of oil were used to make 31 billion plastic water bottles — and more than 31 billion plastic bottles won’t decompose per year.  That’s a lot of plastic! So bring along your own water bottle, and you’ll do a service to both your health and the environment.  A win-win situation!
