What consequence resulted from the stripping of prairie grasses in the 1920s?

1. Increased biodiversity in the region

2. Destruction of farmland and health issues like "dust pneumonia"

3. Improved conditions for farming

4. Reduction of soil nutrients

The correct answer is: Destruction of farmland and health issues like "dust pneumonia"

The stripping of prairie grasses in the 1920s, particularly during the Dust Bowl era, had severe environmental consequences, primarily leading to the destruction of farmland and health issues such as "dust pneumonia." Prairie grasses play a critical role in anchoring soil and preventing erosion. When these grasses were removed, the soil became loose and easily swept away by winds, causing massive dust storms. This loss of topsoil not only devastated agricultural land but also created significant health risks for individuals exposed to dust-filled air, leading to respiratory problems known as "dust pneumonia." The combination of agricultural failure and health crises underscored how essential prairie grasses were to maintaining both the ecosystem and human well-being in the region. In comparison, the other options do not accurately reflect the consequences of prairie grass removal. Biodiversity would likely decline, conditions for farming worsened, and the soil nutrient levels were negatively impacted, rather than improved.
