For example, in the physical sense, an estimated 10 billion land animals are slaughtered for their meat every year in the U.S., yet most of the animals are never seen—they are kept in confined animal feeding operations, invisible to the public and off limits to the media.
舉例來說，在生理層面上，美國每年估計有百億隻的陸地動物遭到屠宰食用，但這些動物大多並不為人所見，全都關在密閉型動物飼養場裡，大眾看不見，媒體接近不了。
