Lab-grown meat.
“In 2013, the world’s first cultivated meat burger was served at a news conference in London. It allegedly cost $330,000 to make. That figure has plummeted in the almost-decade since, but cell-grown proteins are yet to clock in anywhere close to the same price as conventional meats.” (Source: https://www.bonappetit.com/story/lab-grown-meat)
The goal is to get the price down to a level the average supermarket shopper can afford, and if the science is successful it has the potential to revolutionize the food chain.
I’m inclined to agree, at least initially. I suspect it’ll depend on how much demand and competition there is in the field once it’s democratized. The other consideration is extraneous factors (e.g. soaring price of meat due to climate change) that could make lab-grown the cheapest/best option eventually.
