I play on noble difficulty and I'm having trouble with my citites growing over 12, because It doesn't have that much health, so usually it ends upstagnant or starving. It will be a problem because I'm about to be able to build facrories, but then there will be an even bigger concern.I've built aqueducts, and if i have to, I'll switch to environmentalism, however, There is another civic i like in the same category. what are other good ways to increase health later in the game?
