The Frog Scientist and the EPA


Way back in 2002, Dr. Tyrone Hayes, profiled in THE FROG SCIENTIST, published a scientific paper demonstrating the harmful environmental effects of atrazine, one of the most commonly used herbicides in the U.S. In response, Syngenta, the giant international company that makes atrazine, set off on a decade-long smear campaign to discredit Dr. Hayes and his work. Syngenta’s personal and professional attacks on Dr. Hayes were reported in a 2014 NEW YORKER article. Now the U.S. Environmental Protection Agency has finally released a risk assessment acknowledging that atrazine may be doing serious harm to plants and animals, including mammals, birds, fish and amphibians. A report on the human health effects of atrazine is due later in 2016.

As Dr. Hayes said to MOTHER JONES magazine, “The science has been settled for a long time. Now it’s politics and economics.”
