> the only way it’ll work is if we have giant (semi-)open vats like salt evaporation pools that convert solar energy directly into protein and fat if we could replace the typical cattle pastures of today with this other system (basically the same idea without needing an organism that has a nervous system attached to it), I think we'll be closer to "making it" > with an engineered biome that responds to contamination like an immune system I saw a farmer once demonstrate how their barn has an automatic ventilation system that kicks in when the temperature gets too high :)
