What is one of the main concerns regarding the use of pesticides in agriculture?

The main concern regarding the use of pesticides in agriculture is their potential to cause environmental harm and impact non-target species. Pesticides are designed to control pests and diseases that threaten crops; however, their chemical nature means they can also affect beneficial insects, wildlife, and ecosystems if not used carefully. For instance, pesticides may harm pollinators such as bees, which are crucial for the pollination of many crops. Additionally, runoff from agricultural fields can contaminate water bodies, affecting aquatic life and the broader ecosystem. This aspect of pesticide use raises important questions about sustainability, biodiversity, and the long-term health of the environment, making it a significant concern in agricultural practices.
