The perfect storm of events for an environmental disaster: drought, depression, and the disappeared prairie grass, plowed under in an amazingly short period of time to make way for wheat and corn. It all led to massive dusters--huge dust storms that displaced thousands of tons of soil and led to the emergence of a giant sand box in the heartland of the country. People all through the area suffered because of the lack of food and other commodities, because they couldn't grow anything on their lands, and because they were inhaling dust and dying as a result. I never knew how bad it was. This story is tragic.
