For health reasons, red meat is our best dietary choice.
No B-12 without it.
Not enough fat to feed our brains and heart without it.
Cats are forbidden to eat.
Look up fish, clams, other shellfish, octopus, caviar. Very rich in B12.
I’m not suggesting that people *should* stop eating warm-blooded meat. I’m just predicting that eventually, we will, for the most part.
Don’t worry; you won’t be alive, then. Meat-eating has a long life to go, yet.
