The lead researcher of a new study is calling for improvements to some of Canada’s waste water treatment facilities after finding that introducing the birth control pill in waterways created a chain reaction in a lake ecosystem that nearly wiped out a freshwater fish.
The study, which is being published in Philosophical Transactions of the Royal Society B on Monday, found that introducing small amounts of estrogen into a lake led to the near extinction of the fathead minnow because it interfered with the fish’s ability to reproduce.
