== Terraforming requirements ==
Terraforming is started via a button in Planet Detail view. The world must be surveyed and within your borders. Only habitable worlds and [[File:Planet barren.png|24px|link=Celestial_body#Barren]] barren worlds that have the rare {{iconify|Terraforming Candidate}} modifier can be terraformed. The expansion planner screen can be used to find these rare candidates.

It is possible to terraform inhabited planets if the empires has the {{iconify|Ecological Adaptation|24px}} technology. Doing so inflicts a {{red|-20%}} {{iconify|Happiness}} penalty on the planet for the duration of the procedure.

{{iconify|Ecumenopolis}} worlds are created via {{iconify|decision}}s rather than terraforming. They must be inhabited but pops do not suffer a happiness penalty during the process.

The following {{iconify|planet modifier}}s are always removed when terraforming a planet:
* {{iconify|Bleak|26px}} 
* {{icon|Irradiated pm|26px}} Irradiated 
* {{iconify|Hazardous Weather|26px}} 
* {{iconify|Hostile Fauna|26px}}
* {{iconify|Wild Storms|26px}}
* {{planet modifier|pm_planet_from_space|1|Second Home|w=26px}}
If the planet is being terraformed into either a {{icon|machine world}} Machine or {{iconify|Hive World}} the following modifiers are also removed:
* {{iconify|Atmospheric Hallucinogen|26px}}
* {{iconify|Atmospheric Aphrodisiac|26px}} 
* {{iconify|Lush|26px}} 
* {{iconify|Natural Beauty|26px}}
If the planet is terraformed into a Machine World, the {{planet modifier|pm_unity_symbol|1|Paradise Made|w=24px}} modifier is also removed. Additionally, if there are any {{iconify|Pops}} on the planet without the {{iconify|Cybernetic}}, {{iconify|Mechanical}}, or {{iconify|Machine}} traits, they're all killed and an [[File:D bubbling swamp.png|32px|link=Planetary_features#Organic Slurry]] Organic Slurry deposit is added.

When and if terraforming a planet to Hive or Machine World, keep in mind that all planetary features, excluding a few rare ones that give access to rare resources, will always be removed.
