WHAT DROUGHT? There's PLENTY of water in U.S.A.

Despite all the news about the world getting hotter and drier with climate change it's worth noting that there will ALWAYS be plenty of water just sitting around.  Where?  Just ask any Janitor in America groaning under the weight of trash bag after trash bag weighted down mainly with plastic beverage containers nearly ALL half filled with water, soda, coffee, fruit juice etc. that was tossed away as soon as the bottle became warmer than it was in the fridge or cooler than it was in the microwave.  When water REALLY becomes a scarce resource in the hotter years to come, ample supplies of it will be readily available in dumpsters and landfills across America and the Western world that so casually tossed it away in the nearest rubbish bin.
