Overuse and overexploitation of the soil for cultivation by machinery turned the soil into dust, ultimately leading to dust storms.
These suffocated the people and cattle leading to their death, and clogged the machines and the tractors and damaged them beyond repair.
The bread basket had turned into a dust bowl.
From this experience we learn that we should not overuse and over exploit our resources because it leads to ecological damage and environmental imbalance.
To avoid that we should have respect for nature and ecology for a better future.
