I hate to say the sky is falling but maybe it is this time. The west is actually a desert that had a wet period. As populations grew in the west and the need for water increased rivers were diverted and used. Wells were drilled into the aquifers and as the water is used up the wells go deeper an deeper. On the news, California wells are being drilled to 1000 feet at a cost of $300,000. When the water comes to an end as it seems will happen the populations will have to mass migrate back to the east. As the oceans rise and population migrate inward it looks to me like more sky falling. I am amazed how little attention is being paid to what looks like a disaster in the making and that a Manhattan type program isn't going on.
