The program is about corpse-eating and the range of ethical dilemmas associated with different kinds of corpses (meats). It will focus on people's rationale when eating animals.
That is, it's not asking "should we eat meat", but rather, "can any meat be deemed ‘more ethical’ than others"....
...which is why Peter Singer and co are absent from the Panel.
At least we have people in the Audience! Unfortunately, I suspect a question thrown towards veg*ns will be something of a token gesture.
