Understanding the effects of pesticide use on ecosystems is significant due to their potential to disrupt ecological balance and harm non-target species. Pesticides often target specific organisms but can unintentionally affect beneficial species and alter food webs, leading to biodiversity loss. Additionally, pesticide runoff can contaminate soil and water, impacting aquatic and terrestrial ecosystems. These disturbances can compromise ecosystem services, such as pollination and natural pest control, which are vital for agricultural productivity and food security. By studying pesticide effects, we can develop safer alternatives and promote sustainable agricultural practices that protect both ecosystems and human health.
