RE: Water as a ResourceI second that opinion. The way the resource is being dispoiled, overused and wasted. In any number of countries it's unsafe to drink the tap water or any bottled water the source of which is unknown or if the bottle seal is broken.
No ice, No salads, No fruit you don't wash yourself and if you've ever had amoebic dysentry you will forever avoid unknown water sources. Sometimes swimming in the Ocean isn't safe as it too can be polluted with untreated sewage in certain parts of the world close inshore near public beaches. Beer is OK
