Identify a potential environmental impact of pesticide use.

Loss of biodiversity is a significant environmental impact of pesticide use due to the way these chemicals can interfere with entire ecosystems. When pesticides are applied, they not only target pests but can also affect non-target species, including beneficial insects, birds, amphibians, and other wildlife. This unintended exposure can lead to population declines or even local extinctions, which disrupts food webs and ecological balance. In ecosystems where pesticide use is prevalent, species that are sensitive to these chemicals may struggle to survive, leading to a reduction in overall biodiversity. Healthy ecosystems rely on a variety of species to function effectively, and when biodiversity is compromised, it can result in less resilient environments that are more susceptible to disease outbreaks and environmental changes.

The other options, while they touch upon some consequences or benefits associated with agricultural practices, do not align with the significant negative impact that pesticides can have on biodiversity.
