I don't agree on your analysis of sentience. The term sentience has no concrete meaning, so how can you base your moral judgements on this? Plenty of plant life has senses and are able to "feel" things.
If something (living or not) cannot experience suffering then you can’t harm it, by definition
This follows no definition of harm that I am aware of, and I do not agree with it. If you are not aware that you have been harmed, you are still harmed. So you should also be able to be harmed even when you could not be aware of it. Therefore, I do not accept this sentiocentric (just learned this word) argument.
There are good reasons to treat different beings differently but they should be based on the beings’ interests, not their species
And this is one of those reasons. A human's (or any other animal's) continued existence is mutually exclusive with the food's continued existence. If we do not follow speciest dogma, we might as well eat other humans.
I've heard this tired argument that plants and sentient mammals have the same capacity for suffering so many times. I think it is a disingenuous way of excusing the suffering your choices support.
A plant does not grieve when it's offspring is removed from it. It does not have fear, or joy. Plants don't play with each other and bond.
Yes. They communicate, and react to stimuli. So does a computer, but neither are sentient
I don't think it is disingenuous at all. You may draw the line at sentience, but you have provided no argument for why this is correct. Why must we consider the harm exactly up to sentience? Why must we only consider conscious pain resulting from harm, and not nociception? It is easy to dismiss people as disingenuous, especially if you don't really have any arguments for your case.
I don't see how there can exist any good arguments for where to draw the line, which is why it bothers me when people claim the moral high ground, but cannot offer any arguments on why their behaviour is most morally correct. You can say "reduce suffering of sentient beings", and most people probably agree, but I think it is completely natural to prioritise yourself, your family and friends and your species above other animals. So how much suffering of yourself is as important as the suffering of a chicken. Probably substantially less. I don't think you will ever convince anyone of your beliefs by simply denying that their weightings of human-to-animal suffering is wrong and yours is right.
That's a lot of rationalization with no facts to back it up.
I'm getting a "well ackchually" vibe from your comment. If I put a mouse on the ground next to a flower and told you to stomp one of them to death, You would be comfortable with either option equally?
Yes plants respond to negative stimuli, that doesn't imply suffering on the level of a conscious being.
You're making a lot of assumptions about my beliefs in your comment. I do not believe any animal has more right to life than any other animal. With that said if you are in the woods trying to survive like our ancestors then your biological needs take priority, you can't survive on plants in winter. The thing is that is not our reality. We are wolfing down red meat giving ourselves colon cancer needlessly. Trading suffering for joy, not suffering for survival
That’s a lot of rationalization with no facts to back it up.
I, honestly, have no idea what you are talking about. Which facts would you find relevant in a philosophical discussion on morality?
I’m getting a “well ackchually” vibe from your comment.
I am sorry you feel that way, that was not my intention.
If I put a mouse on the ground next to a flower and told you to stomp one of them to death, You would be comfortable with either option equally?
Honestly I find this example a little comical because I think most people would definitely choose to rid themselves of the pest and keep their pretty flower. However, I do understand your sentiment. I don't think my personal views really matter, but I have some rough hierarchy of living organism ordering how highly I value their interests. For example, I think a human is more important than a mouse to me, so I would rather kill a mouse than a human, if I had to choose. Similarly, I think a hare is more important than a flower, so I would rather kill a flower than a hare.
You’re making a lot of assumptions about my beliefs in your comment.
I am sorry, I have incorrectly conflated your comment with that of the original.
I do not believe any animal has more right to life than any other animal. With that said if you are in the woods trying to survive like our ancestors then your biological needs take priority, you can’t survive on plants in winter.
These to statements are completely contradictory. You are more important than other animals, thus you sacrifice them for you own survival. If you have no more "right" to survival than a hare, how is it ethical to kill it to ensure your own survival?
Plenty of plant life has senses and are able to “feel” things.
Having reactions to external stimulus is different from having feelings. Feelings require consciousness, or sentience.
Even having nociceptors doesn't mean you can experience pain (see the above review in the "Defining sentience" section).
If something (living or not) cannot experience suffering then you can’t harm it, by definition
This follows no definition of harm that I am aware of, and I do not agree with it. If you are not aware that you have been harmed, you are still harmed. So you should also be able to be harmed even when you could not be aware of it. Therefore, I do not accept this sentiocentric (just learned this word) argument.
Yes you can be harmed without knowing it, but it still must have a negative effect on you. If something can't have negative (or positive) experience then how can you say it's being harmed?
If I throw a rock to the ground, it doesn't make sense to say I harmed the rock, because a rock can't experience being harmed. Being sentient is having this ability to experience being harmed. That's why I meant it's by definition that non sentient beings can't be harmed. The word exists to distinguish what can and cannot experience harm (among other feelings).
There are good reasons to treat different beings differently but they should be based on the beings’ interests, not their species
And this is one of those reasons. A human’s (or any other animal’s) continued existence is mutually exclusive with the food’s continued existence.
But having food doesn't necessarily mean harming something. And even if it does, different foods have different level of harm. We can choose the foods that minimize harm.
If we do not follow speciest dogma, we might as well eat other humans.
Indeed meat eaters don't really have good reasons to exclude human meat.
Scientific papers usually define what they are studying.
When I say concrete meaning I mean that sentience is an abstract concept of which we can observe evidence of, but we cannot define clearly what it is. In the report you mentioned, you will see that they give 8 criteria for scientific evidence of sentience, i.e. these do not define what sentience is, but they are criteria that we presume sentient beings should satisfy. They even require several pages to explain the complications of how to define sentience and how to observe it.
I do admit that the extent of study on sentience of animals is greater than I initially thought, and I can see that one might have reasonably sufficient knowledge to judge, with some certainty, which life organism might be sentient (under definitions such as the one used in the report). But it seems to me nearly all animals fall under this umbrella of "some level of sentience", I found this paper highlighting that many insects seem to have cognitive abilities, and might be capable of feeling harm. So to what extent must this go, can you not swat a mosquito in fear of its suffering?
If I throw a rock to the ground, it doesn’t make sense to say I harmed the rock, because a rock can’t experience being harmed
But a rock is not alive, there is no evolutionary force driving its interest, as with all other living organisms. A sea cucumber has no proper nervous system (as I understand from a quick search), and thus could not "feel" pain. Yet, if you cut one in half, I would say that you have harmed it. But this is really just discussing the semantics of the word "harm", the real point is that you are doing something to the organism that goes against its natural interests.

Swatting a mosquito generally doesn't induce suffering, if it's done quickly. And since they are not social animals other mosquito probably won't suffer from the loss.
But yes, if an animal is probably sentient you should avoid inflicting pain to it, for the same reason you should avoid inflicting pain to humans: because they can suffer.
But this is really just discussing the semantics of the word “harm”, the real point is that you are doing something to the organism that goes against its natural interests.
Indeed, but going against natural interests or not is not the point. The point is about suffering. And more specifically the fact that the amount of suffering we inflict to animals to eat their meat would be inacceptable if it was done to humans.
If we do not follow speciest dogma, we might as well eat other humans. Indeed meat eaters don’t really have good reasons to exclude human meat.
Yes they do, speciesism. A quite natural reason.
That's like saying people have a good reason to beat people who don't look like them: racism.

This is like saying it is okay to kill a lonely person with no friends and family, as long as it is an instant death.
The point is about suffering.
I don't agree with you that suffering is the single center concept to base your moral judgement on these issues. Not all living things that i care about are able to suffer, and I do not care about all living things that do suffer. I do not care that i cause a mosquito suffering by killing it (wounding it), if it is sucking my blood, or even just being annoying when flying around me, because I value my comfort above its existence (and suffering). I expect you do the same? This is speciesism.
That's like saying people have a good reason to beat people who don't look like them: racism.
Except we both agree that racism is wrong. We do not both agree that speciesism is wrong.

No, it is more like saying it doesn't cause suffering, which is true. Whether it's ok or not is another matter, but some could argue can be.

I didn't say suffering is the single center concept to base moral judgment on, although some moral philosophers argue it is (negative utilitarians). But suffering is the main problem with speciesism: we accept much more suffering on non-human animals than we do on on humans, for no good reason.
If you care about things that cannot suffer, then you do not care for their well being, since they can't experience well being. It may be a semantic problem here, because I thought caring was about the other's well being.
Anyway what you do care about is not really relevant unless you consider we should just follow our instinctive morality. What I was discussing is what we should care about.
I do not care that i cause a mosquito suffering by killing it (wounding it), if it is sucking my blood, or even just being annoying when flying around me, because I value my comfort above its existence (and suffering). I expect you do the same? This is speciesism.
No, I would avoid causing suffering to the mosquito (for example by moving it our of the room or protecting myself). And if killing it is the only practical way to make it stop being an unacceptable annoyance I would still try to minimize its suffering. It's not speciesism because I would apply the same logic if it was a human or any other species.

Except we both agree that racism is wrong. We do not both agree that speciesism is wrong.
And yet speciesism is very similar to racism. It's the same mechanism. Racism is a discrimination on irrelevant characteristics like skin color, and speciesism is a discrimination on irrelevant characteristics like cognitive ability, cuteness, ability to talk, etc.
In both cases these characteristics are irrelevant when we try to decide whether we can cause suffering to these beings. The only relevant characteristic is whether they can suffer.
