ABSTRACT
Walk into any kitchen around the world and there's a good chance that meat or seafood sit neatly at the center of the meal. This is especially true at any top restaurant in New York, Rio, or Beijing. But billions of people all over the world have hamburgers or pork chops or fish fingers with their families at home every night. Even the poorest people often spend their extra income on some odd cuts of meat or fish bones for soup. In fact, meat and seafood are the two most rapidly growing ingredients in the global diet. Yet in terms of resource use, these are also two of the most costly.
