What is this pollution thing?

[rockyjoejoe2007]

I got an event called "The Grey Days" which occurs randomly if you have the decree "road maintenance". The two choices have an affect on the pollution levels, option 1 decreases pollution by 5050 in the state the event occurs in while increasing government expenses and giving a approval increase of 2.0 for the clergy faction (might be another one to idk) and option 2 increases the pollution in the state by 1010 and decreases the clergy faction approval by 2.0.

However I can't find a pollution meter of number anywhere when I click on the state does it actually do something or it just some cut content that didn't make it into the full game.

Does anyone know? Thanks.

The only reference to pollution which I have seen was that it is supposed to affect the map graphics in some way. But my graphics card is too bad to see such effects.

Nations that are heavily industrialized, particularly in one or few states, will face pollution challenges.
The idea is to simulate the effects that industrialization had, and require you to either pay to keep pollution down (which is expensive and counter-productive to industry), or let it build up and eventually impact health and SoL of your pop groups living in the affected states.

There is no visible metric to it. Though like Grotacias said there's suppose to be a visual representation on the map. I have yet to see this, but you can get an idea of how polluted a state might be by looking at population size of it and how many industries are there (including mining and deforestation with lumber mills). You can visually see the impacts of deforestation on the map, which is a huge contributor to earning pollution quickly. The more leveled the industries are, the more pollution they will generate.
