| > Here's a question: Is it immoral for lions to eat zebras? Lions must eat meat to survive. We can choose not to eat meat and still survive. That's a morally relevant distinction. If you are arguing that because meat-eating is natural then it must be moral, I would direct you to the appeal to nature fallacy https://en.wikipedia.org/wiki/Appeal_to_nature > Here's another question: Imagine the entire Earth is actually a factory farm for aliens. Every time someone dies, their body is actually secretly used for alien food. Would you want Earth to cease to exist? No, but I fail to see how this runs counter to the moral claim that humans eating meat is bad. The correct analogy to your hypothetical would be to imagine that all animals live their full lives and are only consumed upon their death. It would not be morally wrong to eat them then. > Or perhaps a closer analogy, imagine super-powerful aliens take over Earth and terraform Mars and Venus, which they use as human farms. Maybe 30 billion humans live on Earth, Mars, and Venus, leading full lives with everything provided to them that a human wants, but killed at 18 years of age. Alien human-rights activists wish to stop the humans from breeding, and let the population fall to several thousand. They will devote the planets to instead growing Alien Corn. This analogy is not close at all. Animals do not lead full lives with everything provided to them that they could want. The vast majority of farmed animals live horrific lives that are not worth living and are killed very young. Chickens, for example, are artificially grown to reach a large size very quickly and then slaughtered shortly after. The correct analogy to this hypothetical would be a so-called "humane" or "ethical" farm where the animals are free to live in a close-to-natural environment before being slaughtered. I would agree that that is much better than factory farms, and perhaps even morally acceptable if the animals' lives are worth living and they would not have existed otherwise. But, this is not how most farmed animals live. Not even close. |
