(36,827 posts)No it hasn't been "decisively" linked.
First the anti-GMO crowd said the pesticide in GM corn was killing Monarchs. This argument was destroyed by the National Academy of Science.

Now the argument is that milkweed destruction by Roundup is what's causing the decline of Monarchs. That argument is equally nonsensical and the problem is they don't consider the alternatives. Studies that link cause and effect are nonexistent as are any studies that compare GMO to non-GMO crops. Were it not for Roundup ready crops, farmers would still be killing milkweed by other methods more harmful to the environment. Were it not for bt crops, farmers would be using more broad spectrum pesticides that would be killing more monarchs.
