In this post, I am making the assumption that there is no suffering withing the hypothetical situations from which I am creating. Upon reading the first chapter of Peter Singer's "Animal Liberation", I naturally agreed with his argument of speciesism. However, this only takes suffering into account. In regards to death, Singer states this: "In general, the question of when it is wrong to kill (painlessly) an animal is one to which we need to give no precise answer. As long as we remember that we should give the same respect to the lives of animals as we give to the lives of humans at a similar mental level, we shall not go far wrong". Obviously, this conclusion seem unsatisfactory and subjective. I am curious to see how other vegans, sub as myself, tackle this question. The most common answer that I have seen is that once a life begins, it is a moral obligation not to cause it to end. I would agree when applying this to murder, or deer hunting. However, there is a key aspect that differentiates animal agriculture, and that is that the "murderer" is the same individual or group that brought the being into existence. In order to avoid speciesism, I will apply this to a human with similar intellect; If my parents were to painlessly kill me, or to simply not have conceived me, I would not deem it unethical that they have done so. Let me put it another way: In this situation, the only two options are: 1) Not having been born 2) Being born, living shortly and dying painlessly (essentially living a short life. I am aware that painless deaths are not possible efficiently, as conditions must be sure in animal agriculture, but consider my hypothetical and make your own conclusion. I'd love to hear people's responses. Sorry for rambling.
