I'm doubtful of any future space colonization, but given likely resource constraints, any sort of meat would be a serious luxury. As far as I know, plants are far and away the most efficient way we have of converting energy into a format compatible with human metabolism (though now that I type that out, I wonder how plausible creating synthetic carbohydrates from in-situ resources might be).

I completely agree with you. HN is very anti-vegan, so mentioning not eating meat always comes with a torrent of downvotes. I imagine any self-sustainable colony would not have meat in their diet because there is no need for it.
