Scientists have identified more than 200 industrial chemicals - from pesticides, flame retardants, jet fuel - as well as neurotoxins like lead in the blood or breast milk of Americans, indeed, in people all over our planet. These have been linked to cancer, genital deformities, lower sperm count, obesity and diminished I.Q.. Medical organizations ... have demanded tougher regulations or warned people to avoid them. They have all been drowned out. Chemical companies, by spending vast sums on lobbying - $100,000 per member of Congress last year - block serious oversight. Almost none of the chemicals in products we use daily have been tested for safety. "Industrial chemicals that injure the developing brain" have been linked to conditions like autism and attention deficit hyperactivity disorder, noted The Lancet Neurology, a peer-reviewed medical journal. Yet we still don't have a clear enough sense of what is safe, because many industrial chemicals aren't safety tested before they are put on the market. Meanwhile, Congress has dragged out efforts to strengthen the Toxic Substances Control Act and test more chemicals for safety. The President's Cancer Panel recommended that people eat organic if possible, filter water and avoid microwaving food in plastic containers. All good advice, but that's like telling people to avoid cholera without providing clean water. And that's why we need another public health revolution in the 21st century.
