I remember the time in my very early twenties when I believed a conspiracy theory that fluoride in water was killing 50,000 people a year; as the reasoning went, fluoride in the body accumulates over time and reaches fatal amounts in some rather vulnerably unlucky people, and due to some convoluted story there is some industrial conspiratorial cover-up. I came to realize I had been bamboozled by the fringe and, along with some other realized bamboozlements, I began exercising--not excising--skepticism.
Earlier today I had read the AP article on CNN and I do not doubt the veracity of the research that trace amounts of medicine are found in city supplies of drinking water. I do, however, doubt why I or anyone else should be scared. As stated in the article, causative effects are unestablished. The linkage to environmental estrogens is, to date, spurious. What of the estrogens of plastics?
Every week, it seems, the news media warns of some new perilous danger in everyday life and, as I always say, I wouldn't be surprised if next week it's dangerous to sit in a chair. Journalists are notoriously not the most scientifically literate of folks, are always needing to justify their mostly unnecessary existence by filling-in the news gap, and tend to be contacted by fringe groups. Granted, this AP research seems to have been carefully thought out, but at the end of the day they admit "So much is unknown. Many independent scientists are skeptical that trace concentrations will ultimately prove to be harmful to humans."
I understand the need to raise an early alarm if the concerns pan out, but in the meantime I will gulp down every glass of water with no less confidence.
