Voters will decide on an issue this November that affects us all: our right to know what's in our food. Millions of Californians are saying: We want to know, and we have the right to know, if our food has been genetically engineered. Parents, farmers, health care professionals, environmentalists, politicians and labor groups want to know, too. Proposition 37 requires companies to add a few words to labels if their food has been genetically modified. Also called GMOs, these modified plant and animal products have been altered in a lab to combine DNA from one species with another to create combinations that don't occur in nature. An example is Monsanto's genetically modified sweet corn, which has been engineered to contain an insecticide, Bt toxin, within the corn itself. Voters and consumers also have environmental concerns. GMO crops have led to an overall increase in pesticide use, the emergence of superweeds and superbugs, and the unintentional contamination of non-GMO crops with GMO-crop pollens. Here in California, out-of-state pesticide and food companies have contributed $25 million to blanket the airwaves with deceptive commercials trying to persuade us that labeling is too costly, scary or confusing. We've heard it all before. They used the same tactics to claim hardship if they were forced to tell consumers about calories, fat content or other information we use every day to choose our food. We're not buying these scare stories. It's a simple label. We have a right to know what's in our food. This is how our country is supposed to work - we are free to make informed choices. Proposition 37 will help us exercise that freedom about what we eat. We urge you to vote yes on Prop. 37.
