Supports any number of surfaces/planets for which the pollution mechanic is enabled (spores are the same mechanic)
 
 

PS1. With the updated game API v2.0.48+, there is no longer a need to touch the evolution factor, so the mod version v1.0.1 was released.

P.S. 2. To modders: This mod should be compatible with any other mods.

P.S. 2a. This mod is based on the world borders from the map settings, not the surface content, and if any mod (example: Ribbon Maze) creates void cells, then this is not a "world border" and of course this mod will not do what you expect!

P.S. 3. Support by the author for this mod is not expected, but is not excluded
