Junk science isn't behind the push to pass Proposition 37, which would require labels for most genetically modified food. Nevertheless, its proponents correctly point out that the disastrous effects of such substances as DDT and Agent Orange only became apparent years after they were initially cleared for use with scientific backing. Similarly, the effects of genetically modified food probably won't be fully understood for some time.
The question before the voters is do we want to know what's in our food, and should we be allowed to choose whether to be participants in a long-term, uncontrolled experiment?
We are better off because we can read the labels on our food and have some idea of what we are eating. Adding information about genetic modifications will increase our ability to make informed decisions.
