Monsanto’s Roundup Ravaging Butterfly Populations, Study Shows

One of the planet’s natural wonders – up to perhaps a billion Monarch butterflies wintering in Mexico’s pine forests where they are so numerous their cumulative weight bends tree branches – is in danger of disappearing – apparently as a result of the massive over-use of Monsanto’s pesticides and genetically-modified crops. According to the report below the number of Monarchs recorded in central Mexico has, over the past 17 years “declined reaching an all-time low in 2009-2010″.

 

Monsanto’s Roundup Ravaging Butterfly Populations, Study Shows

  • Monsanto’s Roundup, containing the active ingredient glyphosate, has been tied to more health and environmental problems than you could imagine. Similar to how pesticides have been contributing to the bee decline, Monsanto’s Roundup has been tied to the decrease in the population of monarch butterflies by killing the very plants that the butterflies rely on for habitat and food. What’s been shown to be an even greater threat to the population, though, is Monsanto’s Roundup Ready corn and soybeans.

    A 2011 study published in the journal Insect Conservation and Diversity found that increasing acreage of genetically modified Roundup Ready corn and soybeans is heavily contributing to the decline in monarch butterfly populations within North America. Milkweed, a plant butterflies rely on for habitat and food, is being destroyed by the heavy use of glyphosate-based pesticides and Roundup Ready crops. Over the past 17 years, the monarch butterfly population in central Mexico has declined, reaching an all-time low in 2009-2010.

    “This milkweed has disappeared from at least 100 million acres of these row crops,” said Dr. Taylor, an insect ecologist at the University of Kansas and director of the research and conservation program Monarch Watch. “Your milkweed is virtually gone…this [glyphosate use on RR crops] is the one main factor that has happened…you look at parts of the Midwest where there is a tremendous use of these crops and you see monarch populations dropping. It’s hard to deny the conclusion.”
