Estimates are still quite high globally too. Around 94% of all globally farmed animals are factory farmed. 74% of all farmed land animals are factory farmed and virtually all farmed fish
it's been ages since I've seen someone trot out "name the trait" or ntt, so forgive me if I'm a bit rusty.
ntt is a form argument that devolves to the spectrum fallacy or line drawing fallacy. basically, it is clear that humans have a set of traits, and chickens have a set of traits, and we can create a human-chicken spectrum. being unable to point to which part of the spectrum you go from human to chicken or vice versa, being unable to draw a line, does not negate the fact that people are not chickens and chickens are not people.
so I won't be answering your direct question
Not the person you are replying to, but that's not what the point of the name the trait question is about. It is not about distinguishing between species
Why are humans morally considered is not asking why humans are human. Asking why one doesn't morally consider chickens is not asking why chickens are chickens
It is about distinguishing between what matters to ethics. It's not a trait that makes them chickens vs humans. It's about a trait or set of traits that makes someone morally considered
Declaring that humans and chickens are distinct is not sufficient to say to they deserve radically different ethical consideration. Otherwise you are just saying that difference itself = justifying different ethical consideration, which is highly flawed. You could for instance, use that to say any group of humans are distinct in some way and thus deserve different moral consideration. Be it by gender, skin tone, etc.
it is. ethics are a social construct developed by humans to help them understand correct action in human society. chickens are only relevant to the extent that it impacts how people relate to one another
This is rather circular reasoning. You are saying humans only matter because some humans say only humans matter
If we can just declare ethics excludes any group inherently because I said so, then that can lead to pretty bad conclusions
not any group. nonhumans.
