This week, along with the rest of the country, we'll be piling my plate high with abundant turkey, stuffing, cranberry sauce and apple pie. It seems like a fitting time to reflect on food. Today on Sea Change Radio, we check in again with leading food journalist Frederick Kaufman to discuss the factors that go into fluctuating food prices around the world. Kaufman talks with host Alex Wise about the food-commodities market, how our global food pricing system mirrors the widening gap between the haves and the have-nots, and the potential impact of geo-political and weather trends on the availability of food.
