The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture of the American and Canadian prairies during the 1930s. Intensive farming techniques depleted the soil, while a prolonged drought dried out the land. Heavy winds blew the loose soil into huge dust storms, forcing hundreds of thousands of people to become migrants seeking work. The government eventually established relief programs and the Soil Conservation Service to help restore the land and aid those displaced by the ecological disaster.
