Some of that is true. BUT, check out how they managed to survive WW2 over there. Although they had some meat, most of what they consumed was veggies.
Made for a tootin good time.
I don’t believe in a totally vegetarian diet.
But people can survive on lacto-ovo; and with some fishy stuff thrown in.
I believe that some day, we will stop eating mammal meat, by general consensus.
But don’t worry - it won’t happen in our lifetimes (and I really wouldn’t want to live without bacon...)
“some” meat or animal products is enough to survive.
Vegetarian is different than Vegan. Vegetarians still drink milk and eat eggs.
