Biological control is a method of managing pests and diseases by using natural predators or parasites. Instead of relying on chemical pesticides, this approach harnesses the power of nature to keep harmful organisms in check. For example, introducing ladybugs can help control aphid populations in gardens, promoting a healthier ecosystem. This technique is not only effective but also environmentally friendly. By using beneficial insects or microorganisms, farmers can reduce their reliance on synthetic chemicals, leading to safer food production. Overall, biological control supports sustainable agriculture and helps maintain biodiversity in our ecosystems.
