The primary concern regarding the effects of synthetic chemicals on ecosystems lies in their persistence and potential for bioaccumulation. Many synthetic chemicals, including pesticides and industrial compounds, do not easily break down and can accumulate in the environment, leading to toxic effects on wildlife and plants. These substances can disrupt endocrine systems, harm reproductive health, and reduce biodiversity. Contaminated habitats can result in cascading effects on food webs, impacting ecosystem health and resilience. Long-term exposure may also pose risks to human health, making regulation and monitoring essential.
