during the dust bowl, as a result of environmental changes, people did what?
During the Dust Bowl, as a result of severe drought, coupled with unsustainable agricultural practices such as over-farming and over-grazing, people were forced to abandon their farms and homes and migrate to other parts of the country in search of jobs and better living conditions. This mass migration, also known as the Great Migration, reshaped the demographics and social landscape of the United States. Many people who migrated west to California during this time became known as "Okies," as they originated from Oklahoma and other Great Plains states. The Dust Bowl was a devastating environmental disaster that resulted in widespread poverty and hunger, and it highlighted the need for sustainable agricultural practices and proper land-use management.
