What impact do biopesticides have on environmental sustainability?

Biopesticides contribute positively to environmental sustainability primarily by enhancing biodiversity. Unlike conventional pesticides, which can harm non-target organisms and reduce overall ecosystem diversity, biopesticides are typically derived from natural materials such as plants, bacteria, and fungi. They often have specific modes of action that target particular pests, minimizing the unintended consequences on beneficial insects, pollinators, and other wildlife.

By promoting the survival and health of these non-target species, biopesticides help maintain a balanced ecosystem, which is crucial for sustainable agricultural practices. Additionally, they can improve soil health by fostering a diverse microbial community, undermining pest populations in a natural way, and reducing the likelihood of pest resistance.

The other options either suggest negative impacts that are contrary to the evidence supporting biopesticides or imply a reliance on traditional chemical methods that undermines the principles of sustainability. Therefore, the contribution of biopesticides to biodiversity makes them an asset in creating more sustainable agricultural systems.
