Yes, because humans are capable of acting ethically. If we choose to.
But you keep using the weak argument of 'it's natural, therefore it's right' to avoid the ethical concerns inherent in this topic.
No, I don't really feel like I'm avoiding anything because I find nothing unethical with eating an animal. I'm not having to justify anything because I simply find nothing wrong with it, nor contradictory about my opinion, and I've examined it.
Every animal lives with the concern of becoming food for another animal barring your average apex predator in good health. Healthy apex predators rarely if ever fear anything. Humans, lucky us, are apex predators. Just because we can choose not to be, doesn't mean we are ethically obligated not to be. We adapted with brains and tools rather than teeth and claws. The existance of our society is all that prevents our unhealthy or elderly from becoming victims of scavengers, rather than grandparents and loved ones.
People are perfectly free to choose not to eat meat, or animal products, and can have all sorts of beliefs about it, that's all cool. But that doesn't make them more moral, or meat eaters less moral. They're both perfectly valid choices. I'm not arguing that natural = more moral or automatically ethical, but i'm hard pressed to see how the basic function of nature is inherently immoral or unethical. Particularly when take to the extremes where not just mammals, but birds, fish, molluscs and insects are all too "human-like" to be eaten. That doesn't make the slightest bit of logical sense to me as an ethical argument.
Were our prey animals not eaten, they'd either not exist at all, or be eaten by other animals. Not eating them doesn't reduce suffering of animals, it reduces the number of animals. The rest are still going to die horrible deaths - predation, starvation, disease, injury. That's just life.
I figure if an animal wouldn't have an ethical problem eating me, because it doesn't have ethics, then I have no ethical problem eating it,
because it doesn't have ethics.
