How will this work itself out? A few large companies owning the supply-side of lab meat? Government legislation to prevent people from raising animals for food? Lab-meat for city folk, and regular meat for rural folk?
Wild, conventionally farmed, locally raised, imported, free range, organic, insect, lab-grown, algae or plant-based proteins all have strong economic, ethical, environmental, technical or health arguments... and limitations!
Cats are obligate carnivores and dogs are scavenging carnivores. They need real meat to survive and thrive. People with pet snakes also need to feed their snakes meat.
Are we going to ban pet ownership?
But I'm not holding my breath on real lab meat being less expensive than animal meat, even in 30 years.
I'm sure they'll try to create a "meat tax" of some sort to make meat more expensive.
