If anything it's moral justification for not doing that. I was pointing out how I kill living things in order to remain alive, even though I think they are unique individual people and it's troubling and confusing to me (because in order to live, another thing has to die).
I'm an energy well. They are an energy well. I can't hold off the march of entropy if I don't bring in more energy. So I absorb their well into mine.
Until we figure out how to integrate photosynthesis / photovoltaics into our bodies its not worth stressing out over the necessary survival process of killing other living things.
Well it is worth thinking about if one energy well suffers and the other one does not.
We have very little reason to believe that a bean plant is sentient and experiences suffering to a comparable level like a factory-farmed chicken. It actually seems absurd.
