What was the Dust Bowl? How did it happen? And what was the impact? The Dust Bowl was the biggest ecological disaster of the 20th century. Early settlers plow up the naturally adapted grasses of the Great Plains so they can take advantage of the fertile soil of the plains. Then after decades of single cash crop (wheat) the soil had become depleted of nutrients. Then after years of serious drought, the soil becomes almost sand like. High winds on the plains pick up the fine dust and dirt particles creating huge dust storms. These storms could pick up thousands of tons of top soil and deposit it hundreds of miles away, affecting crops, livestock, and people. Many farms failed during this time, forcing many families to migrate further west in search of opportunity.
