I don’t see a problem with artificial meat. Then again I’m not religious anymore. I used to be a Christian but I don’t think there’s anything in the Bible against fake meat. I don’t know a whole lot about other religions regrettably. Theoretically lab grown meat would need less food and water than an animal, plus we could grow just the parts we eat and not have to worry about skinning/gutting/deboning carcasses
My fear with artificial meat is the same with most other artificial things: what it's actually made of. The lowest quality meat is still somewhere around 30% actual meat. The worst cuts, possibly expired, but still meat.
When the only objective is that it has the consistency and flavor of meat and has protein, well, I'm sure all kinds of things can meet that bar. Reminds me of a story once told to me by a guy who works in chemical manufacturing. One of the older artificial sweetners, I forget which one, was a byproduct of the rubber vulcanization process. Yet another byproduct of that process was later used by Subway to keep their bread firm and make it last longer.
No one actually knows what this shit does in the human body after decades of consuming it. The business cycle in the US doesn't allow for that kind of research and proofing before we approve it for human consumption. We just want to know if it will, more or less, instantly kill people. If it just shaves 10 to 20 years off someone's life ehhhhhh.....they were probably the bad ones anyways right?
So I'm increasingly leery of food items where the primary cook is a PHD Chemist.
