In the Next Generation series, a lot of the foods eaten on starships are replicated, i.e., they LOOK like meat but are actually artificially produced from pure recycled energy. In “Lonely Among Us” (TNG), when a carnivorous Antican ambassador wants live food, he is told by Riker that “We no longer enslave animals for food purposes.”

“But we have seen Humans eat meat, “replies the Antican.

“You have seen something as fresh and tasty as meat, but inorganically materialized out of energy from our transporter,” replies Riker.

So the ideal of vegetarianism is there in Star Trek — however, not everyone is a vegetarian and meat is eaten by Humans and various aliens in some Trek episodes. Still, the series does legitimize vegetarianism.

Good luck

And the milk? I spent my summers on my grandparent’s farm and there are few sounds more sorrowful than the sound of a mother cow being separated from her baby before their time so that humans could drink her milk. Would Vulcans tear apart mothers and children so they could have butter? And, again, a milk cow must be bred every year to keep her milk flowing. What would Vulcan do with all those cows piling up since they wouldn’t be making them into veal?

It is my opinion that Vulcans would not merely be vegetarian. Their logic and peaceful philosophy would demand nothing less than veganism.

Vulcan is an arid planet and the logical course to maximize agricultural output would be to grow fruit and vegetable crops for Vulcans to eat, not animals.
