So — what even is a GMO?
A GMO is simply an organism whose DNA has been changed on purpose using genetic engineering. That can mean making a crop resist pests, tolerate drought, or have more of a certain nutrient.
According to the U.S. Department of Agriculture, these modifications are used “to introduce a new trait to a plant, such as resistance to certain pests, diseases, or environmental conditions, or the production of a desired nutrient” (“Biotechnology FAQs,” USDA). That’s the basic idea — but the conversation gets complicated fast.
