The film explores Monsanto, a mega giant in the field of bio-technology (think genetic engineering). A specific focus is placed on the use of Round-Up Ready technology and the effects that it has on cells that are predisposed to cancer. According to the film, currently about 70% of the food we eat is genetically altered in some way. Monsanto has a monopoly in this field, which is scary because they are implementing this technology without fully understanding its effects on human DNA. The film talks about the FDA and the rule of substantial equivalence in the genetic engineering of products that are consumed by humans and other animals.
Bottom line, it's not a conspiracy, it's fact. But it's another one of those things that NO ONE ever talks about. So I am. Watch this documentary now, and then throw out your milk.
