Locally we've had boil orders at least 5 times in a year...and thats not including hurricanes coming in and leaving people standing in 4 plus hr lines for ice blocks and bottled drinking water. Or BP polluting the inlets and reserves. I don't know about a global conflict for fresh drinking water but you can bet its one 'natural' resource that is greatly taken for granted. Nothing like a sponge bath with a gallon of Kentwood or stashed tap when the taps are dry or running black
