Several decades ago, the animals we ate were raised on family farms, and they had mostly pleasant lives. During these last decades, however, the corporate farms that replaced almost all of those family farms routinely torture farm animals far more cruelly than even the Nazis tortured Jews. If we believe in a God who rewards us when we do good and punishes us when we do evil, and extends those blessings and curses to our progeny for generations to come, we had better end this cruelty soon. If you are not aware of how horribly we treat ALMOST ALL farm animals in the U.S., watch the first five minutes of this video and see for yourself how cruel we have become.
What more is there to say?
