I recall when C.A.P.S. exposed a major zoo in this country for sending bison to a commercial bison farm, and on that occasion in my opinion I think they had a valid point, I also recall another well known and respected zoo in this country being criticised for supplying ostrich to a commercial ostrich farm. The question is where do you draw the line?, zoos claim that their purpose is to educate and conserve endangered species, none of this is being achieved by simply rearing animals with a view to sending them away later where they will end up on someone's barbecue when they invite friends round, "Isn't this great we have bison steaks , how marvellous!", I think not. I also think you made a valid point previously concerning the transport of bison to their point of slaughter, which without doubt will be very stressful to these wild animals, they are not domestic, usually docile domestic bovines. I question why when literally millions of domestic farm animals are slaughtered in this country every year, and many do not even have the pleasure of being stunned prior to having their throats slit, this would not appear to be enough to satisfy the tastes of certain omnivorous humans, people who think it is great to have reindeer on Christmas Day being another example. Where do you draw the line on this?, could it be possible that in the future the problem of surplus male elephants and gorillas could be solved by selling them to the "exotic" meat trade?
If you go to certain "markets" in London you'll get a few "exotic" cuts! Abhorrent but true I'm sad to say.
