That's why this new material from the National Science Foundation is such important stuff. As far as the actual scientists of the world are concerned the debate about safety of GMOs- which often let farmers use less pesticides and weedkiller - is over, if it ever existed. If you postulate a conspiracy, you now have to involve THOUSANDS of scientists all over the world, not just Monsanto and company. (BTW, if you see that meme about "37 countries have banned GMOs!" ask for a list, because it's a fabrication. And do you really think evil corporations own the NSF, the CDC, and other top scientific bodies all over the world?) There are plenty of real problems to tackle: let's focus on those and forget this pointless fear.
Today's corn has already been so genetically altered through cross-breeding and other "traditional" techniques that Squanto wouldn't recognize it as the plant he showed the Pilgrims. GM techniques speed up the improvement of crops and increase the selection of tools (genes) agricultural scientists have to work with (photo USDA).
The scientific score is currently one discredited rat study and some bits and peices of slipshod predetermined "science" vs massive efforts by farmers, labs, universities, and governments all over the world that all reached the same conclusion: this is safe. The republication of the revised rat study was released with a claim it had been peer-reviewed, but this was a lie.) Labeling and "No GMOs!" campaigns just build fear. Labeling corn because it was improved with GM techniques is no different than labeling meat "Contains Protein!"
