Somebody who eats twice as much factory-farmed products as he or she needs to is clearly doing twice as much damage to the planet. From a utilitarian point of view, that's twice as bad.

If we are concerned about the exploitation of human workers in countries with low standards of worker protection, we should also be concerned about the treatment of even more defenceless non-human animals.

We are, quite literally, gambling with the future of our planet- for the sake of hamburgers

The most callous, stupid things were done just because regulations required them...It was not until 1983, for example, that U.S. federal agencies stated that substances known to be caustic irritants such as lye, ammonia, and oven cleaners, did not need to be tested on the eyes of conscious rabbits.

Looking back on my career, I think I've been extremely fortunate to be in the right place at the right time in order to have the influence that I did.

If we ever do find a better system, I'll be happy to call myself an anti-capitalist.

The statement "I am in pain" may be one piece of evidence for the conclusion that the speaker is in pain, but it is not the only possible evidence, and since people sometimes tell lies, not even the best possible evidence. Even if there were stronger grounds for refusing to attribute pain to those who do not have language, the consequences of this refusal might lead us to reject the conclusion. Human infants and young children are unable to use language. Are we to deny that a year-old child can suffer?
