This is why it's a good thing that China doesn't just chase profit like we do in the west. The main value I see in vertical farming is having controlled climate. As the climate crisis deepens we're going to see more and more extreme climate events like droughts and heatwaves happening. This has potential to kill harvests and cause famines. In fact, crop failures are already starting to be a problem in North America. Building indoor farms is the best way to ensure food supply stability going forward in my opinion.
