Could The Pill be Killing our Fish?
Every day in Canada, estrogen, from millions of birth control pills, is flushed down the toilet and into our rivers and lakes. And according to a new study from the University of New Brunswick, it could be killing our fresh water fish. Researchers put estrogen into an experimental lake, and it led to the near-extinction of the fathead minnows - even though the estrogen was at tiny concentrations. And that had a dramatic impact on the lake's entire ecosystem.
