What is a common consequence of converting grasslands to agriculture in the United States?

The choice of a reduction in available grazing lands accurately reflects a significant consequence of converting grasslands to agricultural uses. When grasslands are transformed into croplands or pastures, the natural landscape is altered, often leading to the removal of native grasses that serve as important forage for wildlife and livestock alike.

This conversion process typically results in a smaller area of land available for grazing, as it shifts from diverse grassland ecosystems to monoculture fields or intensive farming operations. As a result, the habitats that support a variety of animal species and provide essential resources for grazing livestock are diminished.

In this context, the other options do not align with the realities of agricultural conversion; biodiversity is generally decreased, native species are often compromised or lost, and wetland areas are unlikely to be enhanced as agriculture often leads to drainage and conversion of natural landscapes rather than conservation.
