You probably wouldn't be too surprised to hear that our food supply has drastically changed since the 1950s, but still, the changes are not always obvious. For example, an ear of corn sold today at the supermarket probably doesn't look much different from what would have been sold 60 years ago, but it might be different — very different, in fact.
Perhaps you have heard the fuss about Genetically Modified Organisms. GMos are plants or animals that have been created with gene-splicing techniques or genetic engineering. According to the WorldWatch Institute, corn accounts for 31 percent of all genetically modified crops.
