Doesn't the Bible say that humans have
dominion over the animals?
Yes, the Bible states this in the story of Genesis after God
creates Adam and Eve and the Garden of Eden. Although I myself
believe in the theory of evolution, there are some vegans
and animal rights activists who do believe in the literal
interpretation of the Bible. These individuals would point out
that according to the literal interpretation of Genesis, no
animal ever died in the Garden of Eden prior to the original sin. Therefore, in the Garden
of Eden, Adam and Eve and all the animals were vegetarians.
In this context, the phrase "dominion over the animals" could not have referred to killing and eating them. Many would argue that "dominion" is more accurately interpreted as "stewardship" rather than tyranny. Furthermore, since the Garden of Eden represents the highest ethical ideal, some people who believe in the literal interpretation of the Bible interpret this to mean that veganism is the highest ethical ideal.
In any case, the torture of animals is considered an abomination in every major religion. Yet this is precisely what virtually every person in our society is doing, given how modern animal agriculture industry presently operates. If we pay people in the industry to do this on our behalf, then we are just as responsible as they are. Today, even the farms labeled "Free Range" and "Organic" are typically not much better than standard factory farms. One can not sincerely claim to follow the Bible, the Torah, or the Quran, and then continue on with business as usual on this matter.
