Buy a share in a community-supported agriculture program

           When you buy a share in a community-supported agriculture (CSA) program, you pay a portion of a local farm's operating expenses. In return, you receive weekly boxes of fresh fruits and vegetables in the upcoming harvest. "You can't get it any fresher. You're getting it straight from the farm, sometimes picked that morning," says Ruth Katz, executive director of Just Food in New York City. "It's usually organic and it's much more delicious because it's so fresh. And you're supporting local farms." A share in a CSA costs about $300 to $400 upfront for a 24- to 26-week growing season. Many CSA programs accept weekly or monthly payments, and you may be able to buy a half-share rather than a whole share. Check websites such as Alternative Farming Systems Information Center, and LocalHarvest to find a CSA near you.
