Just to put things into perspective, "all-natural organic" corn is a man-made genetic freakshow. Same with nearly every domesticated plant and animal. There is little natural about them. For tens of thousands of years of controlling exactly which ones breed and which ones do not, we have drastically transformed their natural DNA into something that works better for us. So really, all our food is heavily genetically modified. Modern genetic manipulation simply provides a shortcut to change the genes we want quickly, rather than breeding them until we get the genes we want.
