" Harsher methods of producing animal commodities are always more cost-efficient than kinder ones - in the space and type of food and degree of human care afforded to them - just as harsher labor conditions are often the most economical. When no country is willing to make concessions, and thereby risk losing a market, the only alternative is to drop the subject of animal welfare entirely, and exactly this is happening. "
