I would try lab meat, and I still see as promising. However, I am not sure if it will be possible to produce it in large scale, like the author is questioning. It is a good point, it is expensive! Growing tissues in lab is an amazing idea, I know a researcher who is getting lots of money growing epidermal tissues for cosmetic companies to test instead of using animals.
I'd consider reading cultured meat. I'm also not against eating insects. Some people say that will be forced on us, but I bet that's a long way off.
I am always against this term of "forcing" so extreme hehe. But I agree that in a near future, you will find it is a good alternative, less expensive. So people would really ponder as an alternative in their tables. I came from a culture that isn't used to eating ants, grasshoppers. But we eat a lot of shrimp so why not add more arthropods to our menu ?
The technology will evolve. Just see how electronics has changed over the last few decades. I expect there will still be a market for premium 'real' meat, but does it really matter how a chicken nugget or a hot dog was made? I'd like to see an end to factory farming.
I would love to see that too... I am always looking for eating more ethically produced food. What is called Ethical omnivorism. And for sure eating something produced in lab like I say it would be supported by me. I believe a lot in technology, what I saw in the last 30 years is amazing in general technology, probably you saw that too. But for now I try to research as much as possible about what we find around to shop is less "factory farming" like you said! Buying eggs from a local producer is something that I consider being better than buying white eggs from the groceries that comes from these massive exploratory factories.
