How did the human activities made it worse for the dust bowl in 1930?

Answer 1

Used up all the water.

Answer 2

Human activities such as overgrazing, monoculture farming, and improper plowing techniques stripped the land of its native grasses and disrupted the natural ecosystem, making the soil more susceptible to erosion and the formation of dust storms during the severe drought conditions of the 1930s. Additionally, lack of sustainable farming practices exacerbated the situation by depleting soil nutrients and making the land more vulnerable to wind erosion.
