Is it an incident isolated to Iowa ? Check this article from Greenpeace:
"Austrian scientists fed mice over a course of 20 weeks a mixture of 33 percent Monsanto GMO corn and non-GMO corn. These mice gave birth to fewer babies and lighter babies in their third and fourth litters. Mice fed on non-GMO corn had babies as normal. These differences are statistically significant."
To have a more global idea on the issue and the relation between GMOs and sterilization, read the book "Seeds of Destruction: The Hidden Agenda of Genetic Manipulation" by William Engdahl. Available on Amazon here:
Seeds of Destruction
Publication Date: November 20, 2007
This skillfully researched book focuses on how a small socio-political American elite seeks to establish its control over the very basis of human survival, the provision of our daily bread. Control the food and you control the people. This is no ordinary book about the perils of GMO. Engdahl takes the reader inside the corridors of power, into the backrooms of the science labs, behind closed doors in the corporate boardrooms. The author reveals a World of profit-driven political intrigue, government corruption and coercion, where genetic manipulation and the patenting of life forms are used to gain worldwide control over food production. The book is an eye-opener, a must-read for all those committed to the causes of social justice and World peace.(Courtesy: Amazon).
Between exits 2 & 3 on I-91, there's a field that's normally planted in corn with a large sign publicizing the Monsanto variety growing there. I often think "what if it were planted in industrial hemp with a local pressing facility to turn the oilseeds into biodiesel?"
