Today retailers can source food from wherever it is cheapest around the globe at the touch of a computer key. These days we're able to head down to the supermarket and purchase a vast array of foods from all over the world, no longer restricted by local environmental factors and/or the seasonality of a product: you can get flowers from Africa, fruit from Europe, snacks from Asia and spices from South America. Do you know how far your food has traveled to reach your dinner table?
