OK. I saw the pig – mirror experiment ages ago and it was fascinating – and not surprising.
Mine can switch off electric fencing, open gates, converse, have a sophisticated social structure and like a scratch but until they have opposable thumbs and taste horrible, it is unlikely we humans will stop eating them. Except for the ones with whom we have bonded, the pets.
Nature shows us repeatedly that animals eat each other. Humans are animals with the main differences being our inability to see ourselves as such, our inability to work symbiotically with our environment and that we demonstrate a conscience, occasionally.
Our responsibility to pigs and to all stock is to treat them fairly and with respect while alive and to slaughter them humanely; and not to waste their carcasses.
