Bottled water is a convenient alternative to drinking tap water.  It's portable, discrete, safe, and at times trendy... or so we've been led to believe.
 

Bottled water, in fact, is detrimental to the environment in many ways that are not commonly understood.  There is a great amount of waste associated with the manufacturing, processing, and shipping of the plastic used to make the bottles.  The water in the bottles is often taken from unsustainable sources, and the type of plastic used in many brands should not be re-used, since they leech harmful chemicals including Bisphenol A (BPA).
