The seriousness of the Dust Bowl disaster later led to greater use of crop rotation, reforesting and other techniques to preserve the quality and quantity of topsoil in American and Canadian farms. Many songs, books, and works of art were created to tell stories of the people affected by the dust storms. Some of the most famous of these works are the novels "The Grapes of Wrath" and "Of Mice and Men", by John Steinbeck, the songs of folk music singer Woody Guthrie, and the photography of Dorothea Lange, who took pictures of many Dust Bowl refugees and their families.
