Do you have any idea on what the carbon footprint is for production of vets

pigs and humans have very similar biology, and people can easily catch diseases from pigs. This is the main reason why pork must always be well cooked, as opposed to say beef, from which we can catch far fewer diseases. So any superbugs in pigs (or vets) is indeed a cause for concern.

That said, production of pork also carries a far lower carbon footprint (hoofprint?) than beef, so for those of us not yet willing to become vegetarians but interested in leaving a bit of the planet alive for future generations, pork is a good choice of meat.
