What is one of the environmental impacts of mining operations?

Decreased soil quality is a significant environmental impact of mining operations. Surface mining, in particular, involves the removal of the topsoil and vegetation to access minerals beneath the earth's surface. This disruption can lead to erosion and nutrient depletion, making the soil less fertile for agricultural practices and reducing its ability to support plant life. Once soil quality is compromised, it can take many years, if not decades, to recover, impacting local ecosystems and agricultural productivity.

In contrast, the other options do not typically reflect the realities of mining's environmental impacts. While mining might have some localized economic benefits, it does not inherently improve air quality or lead to increased wildlife populations. In many cases, mining activities can lead to habitat destruction, which negatively affects wildlife.
