What about killing plants (ending a life prematurely)?
I would also add though that if you want to minimize plant death, the best course of action is to stop eating meat and animal products and aim for a plant-based diet, since (by thermodynamics!) the number of plants needed to feed these animals vastly outstrips what would deliver the same amount of nutrients to a human eating them directly.
I don't have any reason to suspect that they don't.
With animals there's a clear connection: they have brains and brains is clearly the part that enables us humans to have conscious experiences.
The burden of proof of the claim "plants are conscious" is on you.
I didn't claim that plants were conscious, and we have no idea what causes the conscious experience. I personally wouldn't say that all humans actually experience consciousness. So no, no clear connection, and no burden either.
Also, it's clearer to us (since we're animals) what sorts of events count as ending another animal's life. Elsewhere it's trickier (Is a field of grass one life, or is a blade of grass one life? How should mycelial networks be counted? etc).
For these reasons, I think it's that applying different logic to different kingdoms is a fairly defensible move.
Many plants have evolved specifically around being eaten by other animals.
No, that would be different organisms.
There are also several fungi and protozoans who migrate between the digestive tracts of animals that eat each other (https://en.wikipedia.org/wiki/Toxoplasma_gondii for instance).
I'm not enough of a biologist to defend the point especially well, but doesn't it make sense that one would use different types of reasoning to manage relationships with different types of life?
Right, but that's not the plant, that's the fruit. If you eat the plant itself, it's dead. Same as a cow.
I'll grant that no plants come to mind that have a niche that requires them to be wholly eaten, but I still think that deciding whether to eat a plant requires totally different logic than deciding whether to eat an animal.
So what's your position? Are you here to suggest that "we shouldn't eat animals" is absurd by equating it to "we shouldn't eat plants?"
Or are you a vegan looking to take it a step further by not eating plants that have to die in order for you to eat them? Because I'd like to hear more about somebody who sincerely held that belief.

I just don't understand how you can have a moral outrage to killing one thing but not another. People seem to do a little dance about plants being not as alive as animals to justify it, but it doesn't make sense to me.
There are parasites for which being eaten is a part of their life cycle.

Black widow spiders are so named because the females eat their mates. Some spider mothers become food for their own children.
Not to mention that (while not exactly what you asked for, but I think it's important to recognize) carnivores kill other species as a means of survival, and even their own species at times. Wild wolves cannot feed their pups without killing other animals. Death is common in nature.
The spider thing is interesting though. It would seem that being eaten by her children is an adaptation, not just an unfortunate consequence of harsh reality. The strategy appears to be: give my nutrients to my offspring, for they carry a part of me, and the survival of that part is more important than the rest.
Given that most of the cells in a human body are passengers, and not cells with human DNA in their nucleus (if they have nuclei at all), it seems pretty likely that something, somewhere, is making the same kind of sacrifice, and using a hungry human as the vehicle. And I think that ending a life on those terms falls in a different domain--both from an ethics perspective, and from a "how adversarial of an environment do you want to create for yourself"-perspective, than mere predation.
Strategies of that sort are more popular outside of the animal kingdom than in it (I think), which I think justifies a "different rules for different things" approach.
Ultimately, many grazing animals have their property. If their numbers grow too large from lack of predators, they'll consume all available food and then starve en-masse.
Else I might kill myself, except it is not allowed by my animal programming, which is out of my control, so I go back to that hoping phase.
I also wonder what’s the problem with killing sentient animals while we also kill fellow humans when “necessary”. We kill for our little ego, so let’s just keep fingers crossed that the sacrifices we force are worth something.
Maybe this is a bit Buddhism centric but it takes off my mental loads a bit.
It doesn't require it at all.
It's a lossy conversion.
There are still inherent issues with dairy, such as forced impregnation and abduction and murder of the offspring, so it isn't great no matter how you slice it. But if we're to compare dairy operations, this one was pretty good I guess.
When the cows stopped producing much milk, they had some way of pasturing them for around 2 years before they'd then slaughter them for meat. In total the cows had quite long and low pressure lives. The dairy and meat was very expensive, though. I think that's the realistic outcome of treating animals more morally. It isn't cheap.
