just recently found the game a couple days ago and im hooked, i've heard of pollution but didnt' realize it was a problem because i can't see it.. Can't turn it on either, I've clicked the options under graphics, and also tried F4 "Show pollution vaules" but I can't seem to figure it out... i've seen pictures of people getting a red indicator of their pollution and i don't get this..

Since 0.15, pollution display can be switched on and off when in map mode, by clicking on the red square under the minimap.

If you are still on 0.14 the alt key will show pollution on the map (hot key M).
