After some play on the last era, I guess I find something missing with pollution, we don't have enough feedback about how the decision we are making is really bad.

Since the threshold of 20 pollution per territories is really important (-50 % Food Industry Gold Science Influence Faith) we should have some warning about it. I know it's not something we display for now, the output of a territory, but we should really have a sup up when we take action.

So when I place a new quarter in this region :

We could have this information displayed : (in this case I try to build a Strip Mining Complex (+ 15 pollution) )

Or if it's too complicated, just display the 22 pollution as a reminder on how far the pollution will be for this territory.

For the improvements, the information on the city is nice but not enough to know if we take the -50 % penalty in any territories.

Cant become

Because it will take too much space. So maybe we should leave it this part.

If you already working on a change for pollution, we don't need to add those change, but if you don't we should really improve this part on UI.

After a lot of investigation, I find there are two icons for city / territories to display when we pass the pollution threshold (+ 20). I display the icon here, but it can be nice to add an entry in the Encyclopedia for in game investigation.

With the "new" icons I discover x) , maybe we can do a change for improvements :

To display how all territories will be after the build.
