This March, voters in Mendocino County, Calif., will vote on whether or not to ban the raising of genetically modified crops in the county.

Many see the vote as symbolic, because the primary crops in the county are wine grapes and pears — neither of which have GM versions. However, it will be the first county in the nation to take such a vote. And backers of the bill are hoping that it inspires other counties in the U.S. to take a stand against GM crops.
