Genetically modified organisms (GMOs) are in many of the processed foods that you eat today -- you just don't know it. 85% of corn and 91% of soybeans grown in the U.S. are GMOs. Because rapid genetic modification is a relatively new technology, there are those who are concerned about the long-term effects of ingesting GMO food. California voters tried to make GMO labeling mandatory in the state but it was shot down on Election Day due to the nearly $30 million spent by companies like Monsanto and DuPont to oppose the bill. Supporters say that any hope for a democratic debate was drowned in a sea of money.
