Define "life". Because last I heard, plants count as "alive" too?
One of the possible alternatives I'm aware of is ground up insects. Those are the same kind of "alive" as other animals, and yet AFAICT the "don't kill anything" people seem to things it's at least less bad. Even tho it takes a lot more of them to get the same amount of nutrition.
Are you aware of things called "obligate carnivores"? How do they fit in to your moral framework?
Have you played with evolutionary algorithms? Systems that have appropriate sensors / feedback loops to avoid harm to themselves (could even be as simple as a speed governor on an engine)? It can really be... odd to try to think of "life" (or even whatever term we're currently using to assign moral weight to anything capable of feeling pain) in general as being all that unique and special, when I can build something that meets most parts of most definitions in an afternoon.

Humans are omnivores, and I have the teeth to prove it. Stop demanding that I forsake my heritage, especially over some half-baked philosophy that isn't even compatible with my experiences.
It's easier to empathize with mammals, but you're right, at this point, humans cannot survive without destroying (some) life.
Edit: I'm fine with the ecologic/economic argument for minimizing meat consumption, though.
Humans in space (beside the few scientific missions and maybe a Mars trip) make about as much sense as motorized fishbowls on highways. Humans won't leave the solar system, and we may destroy the ecosystem that feeds us before we can start a serious space expansion program.
Beside the CO2 problems (warming and ocean acidification), we've also destroyed a third of arable land in the last 40 years. The presence of biodiversity is needed for resilient ecosystems too.
I just do not get the obsession with having to have meat every day multiple times or the 'entitlement' (that might be the wrong word I used?) for people feeling they can demand it like that. But that was more of a discussion topic attempt than getting people angry or something like it.
Cool. And given the general tone-deafness of plain text I should probably note that I wasn't trying to go off on you either. I was more going for putting out a variety of thoughts on what seemed to be the topic to see if any interesting discussions might come out of it.

That's probably it, yes. Not sure what the right word would be, tho...
The argument is something like "don't call me entitled I'm entitled to eat as much meat as I want"
... which makes no sense to me.
