Yes. It is because than the farm animals would over populate, and they will eat lots of food. Than there wouldn't be enough food for others and they might go extinct. Boom, nerd just just did nerdy stuff, lol
I thought it would have been the opposite, we would just let them be and they would not have any way to survive in the wild, and they would probably go exctinct unless a cow manages to mutate in the last second.
Alpaca and Llama too lol, but farm animals wouldn't NOT exist. I'm hoping you're not saying cows and chickens would NOT exist. They wouldn't not exist just because people didn't eat them.
