The Dust Bowl in the Great Plains caused people to leave due to crop loss and economic hardship.
The Dust Bowl in the Great Plains during the 1930s was a result of severe dust storms and drought caused by over-farming and dry farming techniques, leading to wind erosion of topsoil.
As a direct consequence, people left the Great Plains after losing their crops to drought and dust storms, and their farms to foreclosure due to the devastation of the land.
The Dust Bowl exemplifies the environmental catastrophe that deepened the agricultural crisis during the Great Depression, forcing millions to migrate out of the region.
