The Great Plains Region of the US experienced a severe drought in the 1930s. The soil dried out and turned into powdery dust. Prime agricultural land was lost and millions of people were displaced. Poor farming practices by farmers in the region led to soil erosion. More soil damage was done by tractors and plows, which were used to till the soil. The environment, society and economy of the region suffered because of it. The Dust Bowl made the soil unable to support crops and vegetation for many years. Due to the Dust Bowl farmers were rendered redundant and migrated to other regions in search of work.
The resulting dust storms, known as the Great Plains region Dust Bowl, made the federal government implement programs that helped to prevent future environmental disasters and promote sustainable farming practices in the region. For instance programs such as the Soil Conservation Service, which aimed to help farmers conserve soil and water resources and prevent erosion were implemented. The Dust Bowl was a significant environmental disaster in American history.
