The Dust Bowl of the 1930s was a period of severe dust storms and drought in the central United States that greatly damaged agriculture. Over 500 people died from dust pneumonia or malnutrition during this time as dust storms sometimes blocked out the sun. The drought affected the Southern Plains and turned 100 million acres of land into wastelands, worsening the Great Depression. Many farmers lost their homes and jobs since the dust killed their crops and caused a widespread drought.
