That's fallacious. Cows, pigs, sheep, turkeys, all existed before being farmed. And still exist in the while. Probably not on the scale of the 60 billions land animals slaughtered each year, though.
Domesticated farm animals are far enough removed from their wild cousins to be their own species. They have been selectively bred over millenia for traits that make them easy to exploit for humans. Most of those traits work against them in the wild.
This is what I'm saying - those 60 billion won't exist. Yes, wild animals, so much as they exist now, will continue to do so, but that's not really relevant.
How is it not relevant. If we stopped breeding animals that doesn’t magically mean that we go back in time 60 billions years and kill every species of farm animal that had existed in that time.
