30 year pescetarian here. I mean, mainly vegetarian but some fish every so often.
I gave up meat at 17 on the basis of no reason whatsoever, I was just a contrary teen who liked giving things up.
Down the line a few years I find so many compelling reasons to not eat meat. Each individually may be argued out of the room but collectively it's pretty compelling.
Ethically: there's no arguing meat eating is better. None. However well you treat animals you're still ultimately going to kill them.
Environmentally: a hundred reasons to choose a plant based diet, all of which have been cycled here a million times so won't go back through it but we all know it's true.
Health: again, see pretty much all the research ever. Eating a plant based diet is so much better for weight, health, BMI, etc etc etc
Taste: this is the kicker imo. If you'd asked me 15 years ago when the vegetarian alternative was a crappy pasta with tomato sauce, I'd have been more tempted to chomp my way into a steak. Nowadays? There is SO much good vegetarian food. Loads of choice, huge range of flavours and in many places it's the vegetarian food that gets the chef's attention, rather than falling back on the Default Meat.
I totally support anyone making whatever decision they like about eating meat, but I'm completely unable to agree that it's a good idea.
Cultured meat in this context is a difficult one to parse. For people like me there's literally no point. I'm just not interested in eating steak, whether it's killed or grown. For your hardcore fleshy, a bloody slab of meat is all that's going to satiate them, so it misses that market too. I guess there's maybe a middle ground of people who could be convinced to stop eating killed meat if they see an alternative?
It'll be interesting to see where this one goes and how it is marketed...
