Butterfly – Ten Percent Remain

Monarch butterflies need milkweed. It is the only plant they can lay their eggs on and that the caterpillars can eat.

But the combination of genetically engineered corn and soy and weed killers like Monsanto’s Roundup herbicide has wiped out nearly all the milkweed that used to grow along the monarchs’ migratory routes, leaving the butterflies nowhere to lay their eggs

Every fall, for thousands of years, hundreds of millions of monarch butterflies have taken to the skies, flying more than 2,500 miles across Canada and the U.S. to reach their winter home in the thick forests of tall oyamel fir trees that grow in Mexico’s Sierra Madre mountains.

This winter, only 33.5 million butterflies made it to Mexico – the lowest level ever reported.

Like honey bees and other pollinators, monarch butterflies are now in crisis, with populations plummeting dramatically since the introduction of herbicide-ready corn and soybean crops in 1997.

They may disappear. Soon.

The huge increase in the usage of GMO crops and the toxic herbicides like Monsanto’s Roundup that accompany them is a major culprit for the monarch’s disappearance, along with rapid deforestation in Mexico and extreme weather caused by climate chaos.

The world needs monarch butterflies. But they can’t survive without milkweed. And milkweed can’t survive weed-killing chemicals . . .

Tell the USDA and the EPA to adopt tough restrictions on pesticide-resistant crops and the toxic herbicides responsible for the rapid disappearance of monarchs.

Sharp Decline of the Monarch Butterfly

A new census found this winter’s population of North American monarch butterflies in Mexico was at the lowest level ever measured. University of Kansas insect ecologist Orley R. Taylor talks to Yale Environment 360 about how the planting of genetically modified crops and the resulting use of herbicides has contributed to the monarchs’ decline.

Taylor talked about the factors that have led to the sharp drop in the monarch population. Among them 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.

“What we’re seeing here in the United States,” he said, “is a very precipitous decline of monarchs that’s coincident with the adoption of Roundup-ready corn and soybeans.
The glyphosate used in agriculture has tripled since 1997, when they first introduced these Roundup-ready crops. The developers of these crops not only provided the seeds that were glyphosate-resistant, but they also provided the glyphosate — the Roundup. And, boy, that was a pretty good system. You could make money on both, right?

It’s a collateral damage issue. And one of the things that we’re worried about now is that it looks like there’s going to be a lot of collateral damage from the use of various herbicides and pesticides coming down.’

In fact, insects such as butterflies, moths, bumblebees and mayflies have been disappearing for a long time, although hardly anyone except specialists has noticed or cared . . . http://www.independent.co.uk/opinion/commentators/michael-mccarthy-this-isnt-just-about-bees-ndash-it-affects-everything-2189269.html
