Browsing social media, it’s apparent that people are quick to point out problems in the world, but what I see less often are suggestions for how to solve them. At best, I see vague ideas that might solve one issue but introduce new ones, which are rarely addressed.
Simply stopping the bad behaviour rarely is a solution in itself. The world is not that simple. Take something like drug addiction. Telling someone to just stop taking drugs is not a solution.
If lab grown meat becomes cheaper than “real” meat while keeping the taste and texture of it or even improve on that, I can totally see that replacing factory farmed meat rather quickly. It’s like with electric cars; people don’t switch if we force / shame them to do so but they will once those vehicles became better than the dirty alternative.
But my point is that we are keeping meat artificially cheap with lots of subsidies. Meat would be a luxury food if people paid the real cost of it, let alone if we paid the long term costs on the environment. I think maybe your analogy would be better with bicycles than electric cars. Bikes are more versatile and convenient than cars in short distances (10km), but most cities have been and continue being developed as car centric. If we used taxes to improve bike infrastructure, people would feel safer to ride bikes more often.
