[[File:Pollution.png|400px|thumb|Example of ingame pollution (red squares) in the map]]
Pollution is represented as an abstract "butt", calculated [[Chunk|per chunk]] and visible on the minimap and [[Map]], when [[Alternative view]] is on (default [[Game-Options/Keyboard-Defaults#Alt|Alt-Key]]).

[[Crafting network|It is produced by many buildings]] involved in processing items and spreads outwards at a steady rate.

[[Pollution Production| Here are some charts to do with Pollution/De-Pollution.]]

== Native life ==
* Pollution attracts [[Biter|Biters]] to your factory. [[Biter|Biters]] who find themselves in a polluted area will attempt to reach the source of pollution and destroy it.
* [[Enemies#Spawner|Spawners]] absorb pollution, but this increases their evolution-factor.

== Pollution dissipation==
* slowly (0.6 units per tick) at every [[Chunk]] (32x32) of map it covers. So the more the pollution spreads, the more is absorbed.
* [[Tree|Trees]] also absorb some pollution (See [[Pollution Production#De-polluters]]).
* [[Enemies#Spawner|Spawners]] absorb some pollution, but this will increase [[Difficulty#In freeplay|difficulty]] by raising the [[Lua/Game#evolutionfactor|Evolution factor]].
* In certain [[Mods]] it is possible to build devices or trees which reduce pollution.

== Modules ==
[[Module|Modules]] that list "+x% pollution" increase pollution multiplier, not a flat pollution rate. Final pollution value is (pollution multiplier * energy usage multiplier * base pollution), meaning heavily boosted buildings are likely to account for most of the pollution produced in a factory.
