The part I italicized in your quote above really doesn't fit. The "virtues of ethics and humaneness" are not owned by, nor exclusive to, Judeo-Christian beliefs. In fact, one could easily argue that Judeo-Christian beliefs include man's inherent dominion over the land and all its creatures by virtue of his place in divine hierarchy, as stated in Genesis, and that this contradicts any claim of being humane to animals being born in Judeo-Christian philosophy. If it was, the spread of Christianity would have been followed with an equally long history of "ethics and humaneness" to animals, but we do not find that to be the case. So...perhaps it would have been best to just not include the text I italicized in your quote.
X2 - Virtues of ethics and humaneness have nothing to do with Christianity or any religion. No particular religious group has the corner market on human morals, ethics, and values.
That being said, I so truly hope that something is done with the way animals are raised in big industry for food. It is a very sad state that we, as humans, continue to condone such horrific practices of cruelty to animals.
