Soil ecosystem threatened

Monsanto Bt crops: genetically modified corn linked to soil ecosystem threat

Bioengineering agricultural giant Monsanto has touted the safety of genetically modified crops, but a new study has found that insecticide-containing corn can be harmful to the overall health of soil ecosystems.

Genetically modified corn has been linked to a decrease in a subterranean fungus that forms a symbiotic bond with plant roots, allowing them to draw in more nutrients and water from the surrounding soil in exchange for carbon.

Researchers at Portland State University conducted a study to examine the effects of corn genetically engineered with the bacteria-derived insecticidal toxin, Bacillus thuringiensis, or Bt, on growth of arbuscular mycorrhizal fungi (AMF).

AMF is important for the overall health and fertility of soil ecosystems, and was found to form less bonds with the roots of Bt corn than with non-Bt corn.

Roundup threatens food supply

Monsanto’s Roundup threatens stability of global food supply

Monsanto’s reckless disregard for public health and the agricultural stability of the planet may be even more significant than previously thought. A shocking new report reveals how Monsanto’s Roundup is actually threatening the crop-yielding potential of the entire biosphere. The report reveals that glyphosate, which was developed by Monsanto in the early 1970s and is the active ingredient in its patented herbicide Roundup, may be irreversibly devastating the microbiodiversity of the soil - compromising the health of the entire planet, as a result.

New research published in the journal Current Microbiology highlights the extent to which glyphosate is altering, and in some cases destroying, the very microorganisms upon which the health of the soil, and - amazingly - the benefits of raw and fermented foods as a whole, depend. Concerningly, certain beneficial strains of bacteria used as food-starters in cultures for raw yogurt, such as Lactobacillus cremoris, have entirely disappeared from certain geographic regions where traditionally they were found in plenty. The study reports that the death and growth inhibition of selected food microorganisms was observed in concentrations of Roundup that are lower than are recommended in agricultural practice.

This means that farmers who are increasingly using larger and larger concentrations of Roundup and similar glyphosate-based herbicide formulations to countermand the increasingly resistant super weeds GM agriculture has spawned, are not only damaging the immediate health of the soil, but subsequent yields of indispensable food-starter microorganisms, as well as the microbes that ensure the overall fertility of the soil for producing crops well into the future.
