We've been genetically modifying foods for years. It was called selective hybridization of mutations. Now, however, science allows us to get ahead of waiting for naturally occurring mutations by splicing desired genes directly into the species we want to modify. This has allowed us to grow much more food per acre in some cases or greatly decrease the loss per acre of food to various insect and other pests. This has gone a great way to reducing hunger in the world. But it's like almost anything, there are risks and benefits. But before we decide that the small risks outweigh the benefits to the companies like Monsanto who profit from these man-made modifications (so many, especially the usual suspects on the far left, seem to think only in terms of the profits of this or that corporation) we ought not forget the benefits to the millions of people who are far better fed because of the increase in food that we are able to produce.
