or chicken
or rabbit (but I know a lot don't eat rabbit)
or lamb
If you are not a vegetarian - and I am not, though I don't each much meat - what animal it comes from is technically irrelevant.
I have no problem eating meat but prefer to eat a small amount of meat from animals that have been given a decent a life as possible.
If we all turned vegetarian then sheep, pigs and cows would quickly become rare. No-one could afford to care for animals on a large without a financial return. Animals bred for meat would just die out - is that any better?
