GM = Genetically Modified

Certain crops, like some strains of corn, have been modified to produce the toxins that harm the pests that try to eat those crops - like a genetically built in pesticide; or modified genetically to produce substances that make some pesticides more effective.

The arguments center around whether or not the substances the GM strains produce, or the level of such substances that GM strains produce, are harmful to humans or not.
