Thanks for the advice. Yea I've kinda understood that the ideal infrastructure to land ratio is 2:1. I've traditionally kept it right around there as it bumped my environment score up a point. However, when I acquired water as a resource that threshold seemed to not exist anymore; purchasing more than half my infrastructure did nothing for me. So maybe water must have some effect there. I stopped purchasing land at that point. Because now that I no longer have water my environment dropped down half a star from five. I guess I'll slowly work my way back up to a 2:1 ratio, hopefully that will help. I've heard technology has some effect as well. Will, say, purchasing another 100 tech have any significant effects on the environment?
