What is a benefit of biological pest control over chemical methods?

Biological pest control offers the distinct advantage of reduced environmental impact, making it a more sustainable option compared to chemical pest control methods. This approach typically involves the use of natural predators, parasites, or pathogens to manage pest populations. Because biological methods leverage the existing ecosystem, they often lead to fewer harmful residues in the environment. This not only helps preserve beneficial insects and other non-target species but also minimizes soil and water contamination.

In contrast, chemical methods can lead to significant ecological disruption and can harm non-target organisms, including pollinators and other wildlife. Additionally, chemical pesticides often require stringent application protocols to prevent negative consequences, which can increase the environmental footprint of agricultural practices. Therefore, the emphasis on biological pest control aligns with more sustainable agricultural practices aimed at preserving the ecosystem for future generations.
