Great topic! All food is genetically modified. You and I are genetically modified. All living things are genetically modified. GMO refers to anything that has undergone selective breeding. This can also be defined as a form of natural selection. To say that food shouldn’t be genetically modified completely disregards hundreds of thousands of years of natural selection and evolution. Genetically modified foods are essential for human survival. Hope that this is a good starting idea or point for your essay.
