Seed Savers Exchange

Many people may not be able to say whether or not they've eaten genetically modified food, but chances are they have since 70% of the food available in the U.S. contains genetically modifed ingredients like corn or soy.  Seed Savers Exchange works toward preservation of food integrity:

Seed Savers Exchange is a non-profit organization dedicated to saving and sharing heirloom seeds. Since 1975, our members have been passing on our garden heritage by collecting and distributing thousands of samples of rare garden seeds to other gardeners.

Gardeners and food purists rely on Seed Savers Exchange for untreated, non-GMO (genetically modified organism) varieties of fruits, vegetables and herbs.  From arugula to zucchini, growers have more than 13,000 types of seeds from which to choose.
