Final answer:
Human activity, specifically overproduction, overuse of land, and improper farming techniques, contributed to the creation of the Dust Bowl in the Great Plains region.
Step-by-step explanation:
Human activity played a significant role in creating the Dust Bowl. One factor was the widespread overproduction and overuse of land in the Great Plains region. This led to the depletion of topsoil and made the land more susceptible to erosion. Additionally, the demand for wheat during World War I resulted in the removal of prairie grasses that would have helped prevent soil erosion. Furthermore, improper farming techniques like lack of crop rotation and allowing the land to lie fallow contributed to the loss of soil fertility.
