This is a valid perspective and a nuanced discussion but something I think is worth having!
I think you'd agree that the core of many vegan philosophies is the avoidance of animal harm, and if lab-grown meat can genuinely eliminate that, then it seems like a perfectly logical conclusion to consider it.
The whole point of this tech is to give people an ethical alternative, but you're also right to ask since it's still highly debatable if producing lab-grown meat is really cruelty-free.
You might want to read about one of the early methods where they rely on Fetal Bovine Serum for cell growth, which I think might be a deal-breaker for you.
However, it's important to note that there are a lot of companies now that are using serum-free media, and that's the direction the whole industry is moving in.
So it's more about knowing which brands are truly aligned with your values.
I suggest you keep an eye on the biotech side of things and you'll find the answers you're looking for!
