Seeds
In agriculture and gardening, seed saving is the practice of saving seeds or other reproductive material from vegetables, grain, herbs, and flowers for use from year to year for annuals and nuts, tree fruits, and berries for perennials and trees.
Many farmers often saved seeds for re-planting for future crops, and many also bred seeds for more desirable traits. As the brief notes, farmers have saved their seed for millennia. However, comprehensive seed patent rights granted to a few large agrochemical corporations over the last few decades are destructive to farmers, agriculture as an industry, food security and consumer health and safety.
