There is some interesting history about ancient lakes that dried up over the course of thousands of years. Currently, the Salton Sea, Aral Sea, Mono Lake are examples of lakes that are reportedly shrinking and providing alarming concerns about the man made and natural chemical’s airborne dust possibly causing illness and cancer risks. I am hesitant to use the might’s, could’s and maybe’s re eco disaster. But, there are some substantive studies in Russia re the Aral Sea (which was the fourth biggest lake in the world…no more) and cancers/birth defects. Of particular importance here, is the Salton Sea. Lake Lahotan was a different story but equally fascinating. (Also, see Land Art) (Salton Sea & Dust/Wind Pollutants)
