The frogs turning gay story is actually mostly real. Atrazine is a herbicide widely used in America and a few other countries but banned in the EU. It has polluted a ton of soil and ground water. It's an endocrine disruptor and turns frog intersex or hermaphroditic. It also has effects on humans. The way it passed the EPA is through a whole bunch of lobbying and "we let the company investigate themselves and they said it was fine".
