Jen and I have been talking about this piece for several weeks now. Notably, it was published in 2007, and to my knowledge this stuff hasn't made it to supermarkets yet. But is this form of meat product inevitable simply because, once they get it down, it will be easier and cheaper to produce? Will those who base their vegetarianism on objections to animal suffering be satisfied with this? That is, with no pig to suffer, is it bacon for all? Or will it now be possible for all 6 billion of us to eat meat "sustainably"? Thoughts welcome.
