The first ones were introduced in 1997, soybeans first, then corn. By 2003, 2004, the adoption rate was approaching 50 percent,and then we really began to see a decline in monarchs. And the reason is that the most productive habitat for monarch butterflies in the Midwest, in the Corn Belt, was the corn and soybean fields [where milkweed, which monarchs feed on, grew]
GMO Herbicides Threaten Monarch Butterfly Migration

— “Less than three acres of trees in Mexico were occupied
by Monarch butterflies this winter - about 1/20th of what it has been in the past.
...The scale of the loss of habitat is so big that unless we compensate for it
in some way, the Monarch population will decline to the point where it will disappear.”

Founder and Director of Monarch Watch, Lawrence, Kansas
Among them, Taylor said, is the increased planting of genetically modified corn in the U.S. Midwest, which has led to greater use of herbicides, which in turn kills the milkweed that is a prime food source for the butterflies.

Maybe we need to move to South America where they are still fighting the good fight.edit on 2-4-2013 by GrantedBail because: (no reason given)
