Yet, despite these well-founded criticisms, over the last 20 years factory farming – not only of chickens, but also of pigs, veal calves, dairy cows, and, in outdoor feedlots, cattle – has spread rapidly in developing countries, especially in Asia. Now we are discovering that the consequences may be far more deadly than we ever imagined.
虽然这些批评不无道理，但过去20年来工厂养殖¾不仅包括肉鸡，还包括肉猪、肉用小牛和室外牧场饲养的肉牛¾在发展中国家，特别是亚洲国家得到迅速的推广。现在我们发现由此带来的后果可以比我们预想的要严重得多。
