I'll chime in and add that bottled water, while needed in some conditions, is an abomination in general. In a world running out of potable water, it take about 4 gallons of clean water to make each and every plastic liter water bottle... and the litter from the discarded bottles drives me nuts. Come down to Baltimore's scenic Inner Harbor area, and where the covered over streams flow into the harbor, you will see where thousands of those bottles end up. I think two or three "cleaner barges" stay busy trying to gather the flotsam and jetsam.
