The battle in environmental health regulation revolves around conflicting interests; one side argues for higher exposure levels with limited studies and industry support, while the other side, comprising scientists and health advocates, presses for lower exposure levels citing evidence of harm. The Environmental Health Trust advocates for stricter regulations, emphasizing the importance of lobbying to counter the influence of powerful industries. This ongoing regulatory battle is rooted in a century-old struggle, influenced by financial power, legal representation, and the conflicting evidence on the effects of exposure to environmental factors.
