Genetically Engineered Corn Endangers Aquatic Ecosystems
Nov 15 at 7:07pm by Aileen
The Chicago Tribune reports this week that scientists at Loyola University have established that the pollen, leaves and other plant parts of corn engineered to kill the European corn borer with Bt toxins could endanger the American midwest’s aquatic ecosystems when washed into nearby streams.
When eaten by aquatic insects called caddisflies, the Bt toxin stunts growth and increases mortality. These insects are food for fish and amphibians in the ecosystem. The scientists reportedly ‘feel’ that such unanticipated effects of GE technology need to be investigated, but of course the EPA and USDA (and Monsanto) don’t feel that way at all.
It might be difficult to separate the effects of GE plant wastes from the general toxic overload caused by modern agribusiness mega-farming practices, which also cause death and deformity among aquatic life forms and amphibians in midwestern ecosystems. And while consumers at home and abroad have made it known that they do not wish to consume genetically engineered pesticides disguised as food, the new market for corn as ethanol fodder makes it unlikely that GM corn is going to be phased out any time soon.
