The document discusses the events leading up to and during the Dust Bowl era of the 1930s. Prior to the Dust Bowl, overfarming during World War I had depleted topsoil in parts of the Great Plains. When drought struck in the 1930s, it caused massive dust storms that lasted for years, devastating crops and livestock. Made worse by the economic hardships of the Great Depression, many farmers lost their livelihoods and homes, feeling forced to migrate west in search of work. President Roosevelt established conservation programs to help rebuild the damaged soil and landscape, though most farmers had already left by the time recovery was possible.
