By way of Katherine Geier at the Washington Monthly, an article in by Rachel Aviv in the New Yorker is well worth reading and thinking about.
A quick search did not come up with anybody yet writing about it. Not since Michael Moore's Sicko have I heard of a corporation going to such lengths to discredit someone it wished to silence, so I think it's worth spreading the word.
And who is the object of corporate wrath?
A UC Berkeley professor named Tyrone Hayes who studies frogs.
He discovered that frogs exposed to a herbicide called atrazine developed malformed reproductive systems. This is the second most popular herbicide for use with corn in America. Its manufacturer not only went after Hayes's research, it also attacked him personally in a manner subtle enough to leave his acquaintances simply wondering if the guy was turning paranoid.
Meanwhile, the atrazine breaks down in soil rather slowly, so it can enter some drinking water. If it has such dire effects on frogs, what effect might it have on other animals and on people?
Anyway, I just wanted to add a quick diary to call attention here to the work of others. For the short version, read Katherine Geier's summary at the link above. For the whole article, read the Rachel Aviv link. It reads kind of like a pulp novel, actually, except that in this case, it's true.
