I’m watching Ken Burns Documentary on the Dust Bowl, and interesting that one of the causes of the dust bowl was a wheat hype cycle in western Oklahoma with all sorts of folks theorizing that because they were able to re-form the grassland to wheat land and grow wheat it would somehow cause more rains to come (to an area that is known for droughts) and it was thought the growth would go on forever. Turns out the grasses they replaced had roots like 6 feet deep that kept the soil in place and prevented events like the dust bowl during dry spells.

Basically the hype cycle is as American as Apple Pie.
