This interview was brought to my attention about the suppression of health hazards of specific herbicides and pesticides. This scientist was funded to examine the effects of specific herbicides on frogs relating that to humans, but when his report was released the manufacturer threatened him. The information is available though and a few interesting snippets I included here. You can read the whole interview at http://bit.ly/1p2vZMu
Scientist Tyrone Hayes of the University of California, Berkeley, who discovered a widely used herbicide may have harmful effects on the endocrine system says in an interview on Democracynow.org, “One of my big concerns is that, as of the year 2000—prior to the year 2000, Novartis not only made atrazine, which is used on corn, of course, which is an herbicide, but it also induces an enzyme called aromatase. It causes you to make too much estrogen. And it’s now been shown that this herbicide, atrazine, and this mechanism, is potentially involved in development of breast cancer, for example. Up until 2000, the company also made a chemical called letrozole, which did exactly the opposite: It blocked aromatase, it blocked this enzyme, it blocked estrogen production. And this chemical, letrozole, is the number one treatment for breast cancer. So this company was simultaneously in 2000 making a chemical that induced estrogen and promoted breast cancer, and making a chemical that blocked estrogen production and was being used to treat breast cancer. So there’s a clear conflict of interest there, a clear problem. But when he tried to publish the results, the chemical’s manufacturer launched a campaign to discredit his work.
