I ran across this horrific story on Joel Salatin's blog. Saladin has been a pioneer of regenerative farming for a couple of decades and is the author of several books on organic farming. I would be inclined to trust him.
"Last December at the ACRES USA conference in St. Louis I ran into a guy who knew one of the executives at Monsanto. He told me about a conversation he'd had with this fellow regarding genetically modified organisms. The long and short of it was that one of the primary goals of GMOs was as a population control mechanism. I assumed the conversation had been embellished due to paranoia..
So last Friday I had dinner in Minneapolis and met a fellow and his family who are farming north of the twin cities. He had attended Purdue University in Indiana, was an excellent student, and Dow Chemical hired him right out of college. He described the fancy trucks, the fancy dinners, the fancy resort conventions that the company supplied.
His team was working on GMOs and he found out one day that they were putting spermicides into grain to ship strategically to countries around the world where U.S. foreign policy wanted population control".
