Recently tried an Impossible burger and nuggets and thought that if nobody told me it wasn’t meat, I’d have thought the patty was made out of a weird kind of meat, rather than make a connection with the taste and texture of plants. Honestly, I might not complain if that was the only kind of “meat” I could have for the rest of my life.
Well, maybe I’d miss bacon.
I’ve yet to find the opportunity to try lab-grown meat, but I for sure would like to try it out and don’t see much wrong with it as long as it’s sustainable, reasonably priced, and doesn’t have anything you wouldn’t expect in a normal piece of meat.
Also, with imitation and lab-grown options, I’d no longer have to deal with the disgust factor of handling raw meat (esp. the juices) or biting into gristle. I’ll happily devour a hot dog, but something about an unexpected bit of cartilage gives me a lingering sense of revulsion.
I’m very much not up-to-date on the lab grown meat industry (so take this with a grain of salt), but I have done cell culture.
There’s a reason most scifi with food grown in vats references bacteria, yeast, and algae. Single celled organisms have to be relatively self sufficient. You can grow more yeast/bacteria by feeding plain sugar to it. There are other nutrients eventually needed, but they can be given in simple forms (e.g., oxygen, inorganic salts, etc.) that you can isolate or create through simple chemistry alone.
Vertebrate cells are part of a highly complex system where they require sugars/salts/etc, but also growth factors, antibodies, and a whole host of other proteins, fats, steroids, etc. Some of those can be created in a lab with chemistry or special bacteria/yeast, but for the most part, scientists use fetal bovine serum. It’s a byproduct of slaughtering pregnant cattle, and it contains a lot of those things that are just too hard to create otherwise.
Cells also need to be given the right niche do grow and differentiate into the target cell type, so muscle needs to exercise, arteries need pulsatile fluid flow, nerves need electrical signals, etc. Without an immune system, everything needs to be done in a sterile environment.
All of that adds up to an ecological footprint that’s extremely difficult to reduce below the natural product.
Lab grown muscles don’t need exercise, nor do they need arteries or nervous systems
Your conclusion is simply wrong. Much of the resource requirements in a natural product is the non-muscle portions of the animal, and most importantly the cost of keeping all those cells alive until slaughter
It’s incredibly easy to reduce the ecological footprint, because most of it is not necessary for lab grown meat
