The loss of farms during the Great Depression.

Explanation:

This phenomenom known as the "Dust Bowl" was one of the worst ecologic disasters of the 20th Century. During 1930's (and up to 1932 and 1939) droughts affected the plains and meadows extending from the Gulf of Mexico to Canada. The Dust Bowl effect was produced by persistent drought conditions, favoured by years of soil manipulation that left it vulnerable to the effects of wind. Since its humidity levels were almost zero, soil was lifted up by the wind in the form of big sand and dust clouds. The Dust Bowl multiplied the effects of the Great Depression in the zone and caused the greatest displacement of population during a short period of time in United States' history. Three million inhabitants left their farms during 1930's, and more than half a million emigrated to other States, especially to the west.

the loss of farms during the Great Depression.

Explanation:

The phenomenon of the 1930s known as the Dust Bowl was one of the worst ecological disasters of the 20th century. The drought affected the plains and prairies that extend from the Gulf of Mexico to Canada. The drought lasted at least between 1932 and 1939, and was preceded by a long period of above average rainfall. The dust bowl effect was caused by persistent drought conditions, favored by years of soil management practices that left it susceptible to the action of wind forces. The soil, stripped of moisture, was lifted by the wind in great clouds of dust and sand so thick they hid the sun. These days they received the denomination of "black blizzards" or "black wind". The Dust Bowl multiplied the effects of the Great Depression in the region and caused the largest population displacement in a short space of time in the history of the United States. Three million people left their farms during the 1930s, and more than half a million emigrated to other states, especially to the west.
