Which factor is a major reason for the restriction of chemical pesticides?

The primary reason for the restriction of chemical pesticides is that they contribute to human health hazards. Many chemical pesticides contain toxic substances that can pose serious risks to human health, particularly to agricultural workers who handle these chemicals and to consumers who may be exposed to pesticide residues on food. The potential for acute and chronic health effects, including respiratory issues, skin irritations, hormonal disruptions, and other serious medical conditions, has led regulatory agencies to impose stricter guidelines on their usage.

These health concerns have prompted the development of integrated pest management (IPM) strategies, which prioritize less hazardous and more sustainable methods of pest control, ultimately seeking to minimize human exposure to harmful chemicals. This understanding of human health impacts is crucial for establishing safe agricultural practices and ensuring the protection of communities located near agricultural sites.

The other factors listed do not significantly drive the restrictions on chemical pesticides. Their low cost and ease of use do not justify the health risks posed. While some chemicals may enhance certain aspects of crop production, the potential detriment to biodiversity and human health overshadows these benefits, reinforcing the rationale behind regulatory restrictions. Moreover, the idea that chemicals are preferred for all pest scenarios is inaccurate—as pest management often requires a more nuanced approach that includes biological, cultural, and mechanical methods
