Genetically Modified Maize Does Not Reduce Biodiversity

    Numerous studies from China, Spain and the United States have concluded that the biodiversity of insects and related arthropods is not reduced by genetically modified (GM) rice, cotton, and maize fields, despite the claims and concerns of activists who are against using precision techniques to use natural genes to reduce the use of pesticides, add nutritional benefits, or increase yields. A new study from South Africa published in
    Environmental Entomology
    shows similar results, that biodiversity is
    the same as that among conventional crops.

    A total of 8,771 arthropod individuals, comprising 288 morphospecies, were collected from 480 plants sampled from Bt maize and non-Bt maize fields over a two-year period. The researchers found no significant differences in abundance or diversity in detritivores, herbivores, predators, or parasitoids.

    "The aims of the study were to compile a checklist of arthropods that occur on maize in South Africa and to compare the diversity and abundance of arthropods and functional groups on Bt maize and non-Bt maize," the authors wrote. "Results from this short-term study indicated that abundance and diversity of arthropods in maize and the different functional guilds were not significantly affected by Bt maize, either in terms of diversity or abundance."

    "The results of our study indicate that arthropod diversity, even in high-input farming systems, is as high as in subsistence farming systems" said Dr. Johnnie van den Berg, a professor at North-West University and one of the co-authors of the article. "More recently, surveys of arthropod and plant beta-diversity inside and adjacent to maize fields have been completed during which 30,000 arthropods and 15,000 plant individuals were surveyed along a 1,000 kilometer transect. It seems that maize field diversity is homogenized and field margins had a high beta diversity," he added.


    This reads like an industry funded study that ignores that several pollinators including various species of wild bees and butterflies are in steep decline due to loss of habitat and food sources due, in large part, to industrial agriculture and the use of pesticides.

    Just for calibration, would you have questioned the funding if the results had been what you go into science article predisposed to believe?

    And then, just as a way of clarifying what you may not know, organic corporations use more pesticides than GMOs, they just are not synthetic. Eating an organic toxin is actually not better for you, despite what people selling you something may claim.
