Chemicals damage: Our immune system: causing infections, allergies and cancer. Our endocrine system: causing thyroid disease and adrenal disease and diabetes. Our nervous system: causing learning and behavior problems. Our reproductive system: causing major sexual difficulties, and changes. One word---pseudoscience. Too bad you bought it. This is just more eco-freak propaganda. The simple fact is that we are healthier and live longer on average than at any other time in human history. Most of the "problems" you mention are simply due to our longevity. For MOST of history, the typical human didn't live to make 45 years old.
