A common complaint is that the U.S. government conducts no independent testing of these biotech crops before they are approved, and does little to track their consequences after.Then the article cites some independent research that has revealed evidence to suggest serious problems caused by the consumption of GMO products.
The developers of these crop technologies, including Monsanto and its chief rival DuPont, tightly curtail independent scientists from conducting their own studies. Because the companies patent their genetic alterations, outsiders are barred from testing the biotech seeds without company approvals.
