History

Historical Context

The Dust Bowl, occurring from 1930 to 1940, devastated the Great Plains due to severe drought and poor farming practices, displacing over 2.5 million people. This ecological disaster exacerbated the Great Depression, leading many families, often referred to as "Okies," to migrate westward in search of better conditions. Today’s climate challenges echo this historical crisis, underscoring ongoing vulnerabilities in agriculture and public health.
