Dear EarthTalk: I know that local food has health and environmental benefits, but my local grocer only carries a few items. Is there a push for bigger supermarkets to carry locally produced food? -- Maria Fine, Somerville, MA
By eating locally sourced foods, we strengthen the bond between local farmers and our communities, stay connected to the seasons in our part of the world, promote crop diversity, and minimize the energy intensive, greenhouse-gas-emitting transportation of food from one part of the world to another. Also, since local crops are usually harvested at their peak of freshness and typically delivered to stores within a day, customers can be sure they are getting the tastiest and most nutritious forms of the foods they like.
