Our local Transition group recently organised a 50 Mile meal event. As per the title all ingredients were to be sourced from within a 50 mile radius. Depending on the farming methods used and the relative eco-footprint this can be highly beneficial as it reduces the "food miles" needed to get from farm to plate.
Obviously with 51% of greenhouse gas emissions coming from animal agriculture (The WorldWatch Institute on behalf of the World Bank) it can be said to be preferable to import plants, rather than consume local animal products.
