buying locally raised food is great for so many reasons. small local farmers are much less likely to use tainted, dangerous products that corporate farms (perdue, etc.) use--@ our local farmer's market i saw a lot of signs saying that the meat from various farmers was raised on corn that the farmers grew themselves.
plus buying local supports your local community, & the food is fresher b/c it hasn't flown thousands of miles (the average journey of a piece of supermarket produce is something like 1400 miles). which also cuts down on fuel costs needed to ship it.
all that for food that is safer & tastier!
