The Pill

Here's an excerpt from a fascinating article, What the Pill Is Doing to Our Water Supply, by Dr. Rebecca Oas:

When a new synthetic substance is created, or a naturally occurring substance is generated at greatly increased levels, the effects can be far longer-lasting and wider-reaching than its manufacturers predict or intend. Some well-known examples of this include asbestos, a popular insulation and flame retardant in the late 19th century, which was later discovered to be carcinogenic; and polystyrene foams like Styrofoam, which is frequently used in disposable packaging, yet takes hundreds of years to break down once discarded. In the case of oral contraceptives, the key ingredients are synthetic hormones known as progestins, which mimic progesterone, either alone or combined with estrogen. When used therapeutically in contraceptive pills or in hormone replacement treatments for menopause, these synthetic hormones make their way into the water supply after being excreted in the patients’ urine. As environmental contaminants, these are referred to as endocrine-disrupting chemicals (EDCs), due to the fact that they interfere with the endocrine systems of humans and animals alike following exposure.
