You can also get in on the action yourself by starting a backyard garden. Production doesn't get any more local than your backyard, and there's no better way to ensure that the food you eat is organic than by producing it yourself. Growing some of your own food will lower your grocery bill and your family's environmental impact. If you have a bumper crop, you can donate the surplus and help others, too.
You don't even have to own a backyard to plant a "backyard" garden. Some communities offer free or low cost garden allotments, public lands set aside for citizen gardens that will set the "groundwork" for your very own vegetable patch. Check with your regional USDA Cooperative Extension Office for more information about the availability of allotments in your area.
