Estrogen: an environmental hazard?

Widespread use of birth control pills harming the environment, says "Estrogen overload," California Catholic Daily (April 29, 2007). Tests of river fish indicate their flesh carries enough estrogen-mimicking chemicals to cause breast cancer cells to grow, says Scientific American in an article entitled "Bringing Cancer to the Dinner Table: Breast Cancer Cells Grow Under Influence of Fish Flesh" (April 17, 2007). Finally, even the concept of excess estrogen being passed into the water supply through urine may be plausible and seems to be supported by the following article, "Dr. Lee's 3 Rules for Hormone Replacement Therapy," which says to "use a sprinkle of common sense and a dash of logic."
