We do the same thing to plants. Why do you have no qualms about killing plants to eat the food they accumulated for their young?
A grain of wheat and a chicken egg are evolutionarily and nutritionally, maybe even ontologically, indistinguishable from one another.
Peter Singer has been writing on the topic for decades, including others. What-about-plants needs to fade away.
Even if you accept that plants might be conscious and their suffering has to be reduced, you would still harm way fewer plants by eating them directly instead of eating other animals that consume them.
2) Multiple things can be horrible at the same time. Being upset at this doesn't diminish the atrocities happening elsewhere (like war, genocide, slavery of humans). We can hold multiple things in our heads at the same time.
3) This has nothing to do with the conversation or this domain, but because you're bringing it up, I also have ethical concerns about the experience animals have of their own existence, and reduce or eliminate my consumption when possible.
I also agree, the horrors of the tech domain are usually much more subtle and indirect.
But you're right, these things are all linked and should be considered. I think often about sentience. I see the way animals express deep, complex emotions, and I think humans are a bit naive to think it's state/domain solely alloted to them.
