What if it's an endangered species? Or (insert your culture's taboo meats)?
Is pork made that way kosher? I mean - no cloven hoof. If you're catholic can you eat it on fridays?
What if you used human cells? Is it cannibalism? Is it ethical? What if you use your own cells?
I suspect there are still ethical concerns floating around in there somewhere.
@Biggles (these are great questions btw)
@Biggles definitely, but the ethical concerns around slaughtering animals aren't among them.
