Smith counters that if you factor in the hidden cost of government corn subsidies, environment degradation, and decreased human health and animal welfare, grass-fed is the more cost-effective model.

史密斯反驳说，如果你把政府谷物补贴的隐藏成本、环境恶化以及人类健康和动物保护的减少考虑在内，那么草饲模式更具成本效益。

Levels of iodine 131 entering the air can be very diluted, but if the iodine is deposited on grass eaten by cows, the cows will reconcentrate it in their milk by a factor of 1,000.

碘131进入空气后能被大量稀释，但是如果碘扩散到草地，草又被母牛吃掉，母牛会将碘的含量凝聚到1000倍。
