Wind erosion is a serious problem in many parts of the world. It is worse in arid, or dry, and semiarid regions. Areas most susceptible to wind erosion on agricultural land include much of North Africa and the Near East; parts of southern central, and eastern Asia; the Siberian Plains; Australia; northwest China; southern South America; and North America. Wind erosion is a major problem on about 75 million acres of land in the United States. Wind erosion physically removes from the field the most fertile portion of the soil. Some soil from damaged land becomes atmospheric dust. Dust decreases visibility and pollutes the air and water, causes automobile accidents, ruins machinery, and endangers animal and human health. During the 1930s, a prolonged dry spell culminated in dust storms and soil destruction of disastrous proportions. The "black blizzards" of the resulting Dust Bowl inflicted great hardships on the people and the land. The Dust Bowl has been called our nations worst ecological disaster. It was an area in the southern Great Plains during the 1930's, where prolonged drought and severe dust storms inflicted great hardships on the people and damage to the soil. As if the drought and storms were not bad enough, the 1930's was also the time of the Great Depression. Because of the dust storms, which spread dust across the country, the 1930's are often known as the Dirty Thirties.
