I was just imagining something wild and fun! What if in an alternate reality/universe they had vehicles that we’re grown from plants and ran on biological energy of some kind that wasn’t electricity/gas/whatever we use? Or what if they used highly advanced wildlife and had a mutually beneficial relationship somehow? It’s like a really cool bio scifi possible future. It could even exist in our future. I was thinking about how strange it is to have so many metal machines and how people used to use boats or wagons made of wood and I was like, why not have more biological machines? It might be much more beautiful and interesting than a bunch of metal boxes?
