Environmental Implications of GMOs
Glyphosate, commercially known as Roundup, is the world’s best selling herbicide. It is also a powerful selective antibiotic. By genetically engineering plants with the insertion of certain foreign bacterial genes, glyphosate can be applied directly to crop plants without destroying them.
Scientists and anti-GMO groups have warned that GMO crops, by encouraging liberal use of the glyphosate, were fostering herbicide resistance in many weeds, creating superweeds, plants resistant to the chemicals designed to kill them, and super-pests.
