Bull flap. They use insecticide for non GM crops just as much or possibly more(if the crop is modified to repulse insects )
Monarch butterflies threatened by GM crops in U.S., study says
The evidence points to the U.S. corn belt, where increased cultivation of genetically modified corn and soybean crops comes with a devastating side effect for milkweed.
When GM crops are planted, fields are sprayed with herbicides to wipe out any wild plants that don`t share the crops’ genetically engineered protection. In the past, herbicides would typically be applied early in the growing season, when milkweed seeds are still underground. With GM crops, the spraying happens later, and any milkweed growing adjacent to the crops is hit hard.
Even before GM crops were adopted, milkweed was never overly abundant. Farmers found only “30 or 40 stems per acre,” said Chip Taylor, an insect ecologist at the University of Kansas who was not involved in the study.
Despite the modest number plants, a survey done in 2000 found that “corn and soybean fields were producing more monarchs per acre than anything else,” said Dr. Taylor, who is also the director of Monarch Watch, a conservation and outreach group.
I’m not a scientist and I don’t know anything about butterflies other than they are pretty.
Our bodies are not designed to handle GM foods.
Exactly, the conventional pesticides for insect control for corn and soybeans are far more dangerous to butterflies (and to humans). But you can fool some of the people all of the time...and it is a good fund raising project for University researchers and groups like Greenpeace and Fiends of the Earth who have been carrying this message now for 20 years.
