More than 30 US seed companies have signed a "Safe Seed Pledge", not to use and distribute genetically modified seeds. They state: "Agriculture and seeds provide the basis upon which our lives depend. We must protect this foundation as a safe and genetically stable source for future generations. For the benefit of all farmers, gardeners and consumers who want an alternative, we pledge that we do not knowingly buy or sell genetically engineered seeds or plants."<a href="http://www.gene-watch.org/programs/safeseed/sourcebook.html">The Safe Seed Sourcebook Online</a> THE SAFE SEED SOURCEBOOK
