cows aside, would there be the same amount of pigs, hens, sheep, and other animals that are slaughtered for food if everyone was vegetarian. and not as many cows would be killed if there wasn't a demand for beef. and actually we don't have any leather in our house at all![]()
They just wouldn't be born, if no one ate eggs, no one would keep chickens, they'd go from one of the most populous birds on the planet to almost extinct.
As for pigs, no one would keep them either (except for a very small number as pets)
