Why is integrated pest management considered environmentally friendly?

Integrated Pest Management, or IPM, is considered environmentally friendly primarily because it reduces reliance on chemical pesticides. This approach aims to manage pest populations through a combination of biological, physical, cultural, and chemical controls rather than relying solely on chemical agents. By emphasizing preventive measures and monitoring pest populations, IPM seeks to minimize the impact on the environment, including non-target organisms and beneficial insects.

The focus on less chemical use is key; while some chemical pesticides may still be utilized, they are employed strategically and only as a last resort when other management practices have proven insufficient. This is beneficial because it helps maintain ecological balance, supports biodiversity, and reduces the likelihood of pests developing resistance to pesticides, which can happen when chemicals are overused.

The other choices reflect an understanding of pest management that does not align with the core principles of IPM. For instance, quickly eliminating pests can lead to higher pesticide use without addressing the underlying causes of pest outbreaks. A primarily chemical-based approach conflicts with the IPM philosophy, which integrates various methods for a more sustainable outcome. Additionally, not considering non-target organisms would undermine the environmental objectives of IPM, as it aims to protect all components of the ecosystem, not just focus on pest control.
