Does buying locally really help save the environment? Depending on how and when the produce is grown and stored, maybe not. The Observer investigates the myth of food miles, pointing out that judging the environmental impact of food solely on the distance the food traveled to get to your plate is too simplistic. Many factors go into calculating the amount of carbon emitted by a food that make it difficult to predict its carbon footprint. "There is only one way of being sure that you cut down on your carbon emissions when buying food: stop eating meat, milk, butter and cheese," said Tara Garnett of the Food Climate Research Network.
