Poor farming practices.
<h3>Further explanation</h3>
- The Dust Bowl natural disaster occurred in the Midwest in the 1930s in North America. The effect lasts for a long period in 27 states and drought afflicts 75% of the country.
- Dust and drought shake great an enormous portion of U.S. agricultural production. Undoubtedly this natural disaster even worsened the Great Depression that was happening in the US at that time.
- In addition to factors due to shifting weather patterns that occur over the Atlantic and Pacific oceans, this natural disaster is also caused by poor farming practices because it is unsustainable and poorly planned. That negligence also weakens plants that prevent the soil in place.
- Formerly in the Midwest, prairies grass protected the topsoil and was so profitable. But once the farmers finished processing it, they plowed more than 5.2 million hectares of deep-rooted grass.
- Land wealth just disappeared after years of farming. A strong wind blew the rest of the topsoil, and the drought prevented the plants.
- When the wind blew, they dissipate a massive cloud of dust. It piled up mounds of land everywhere that covered much of the housing.
- The Dust Bowl affected the entire Midwest. Dust suffocated livestock and caused pneumonia in children.
- By 1941, the Dust Bowl gradually receded along with the level of rainfall that had returned to near-normal levels. The Great Depression also ended.
