Between 1930 and 1940, the Great Plains of the United States suffered serious drought. In 1862, which was a semi-arid prairie, Congress passed the "Homestead Act" and the trees-free plain became the home of thousands of settlers. Most colonists cultivate land and grazing cattle. Farmers cultivate meadow grass and plant dried ground wheat. As the demand for wheat products increases, grazing cow decreases and millions of acres of land are cultivated and planted.

Drylan agriculture in Great Plains caused systematic damage to grass field grass. In pastures, overgrazing destroyed a wide range of grasslands. The land was gradually exposed and began experiencing serious environmental damage. Among the elements of nature, the strong wind in the area is particularly destructive.

When drought began in 1930, excessive cultivation and over pasture lands began to run out. The wind blew across the plain and lifted the dust clouds. The sky may get dark for a few days, and even a tightly sealed house may leave a thick layer of dust on the furniture. Depending on the location, dust floats like snow, covering farm buildings and houses. The 19 states in the center of the United States turned into huge dustballs. Because there was no opportunity to make a living, the peasant family gave up their houses and land and fled to the west to become a migrant worker.

In 1939's book, Angry Grapes, writer John Steinbeck says about the family escaping from the dust bowl as follows. "Later, we are deprived of Westerners - From Kansas State, Oklahoma, Texas, New Mexico, Nevada and Arkansas, families, tribal Carbans, caravans, homeless people, hungry people, and 2,500,200,000 people Walking around the mountains, the ants are restless and are hurried to find a job to do - promote, push, pick, cut something, any burden, food is also hungry for children children we live There is no place All lands. "A total of 400,000 people, a victim of a combination of serious drought and poor soil protection measures, left the Great Plains.
