Zorg Empire

Hello again community
well i just want to understand what does this building does because its description didn't tell much, if anything...
what i understood was like it's keeping the planet's environment at good condition but i never seen citizens or anything that requires it, or maybe it boosts the res gain?
Because i gonna build the nanite-factory soon so i want to know if it's worthy

The terraformer increases the number of building fields on your planet by 5.
Remember though that the 5th field will be used to build another terraformer.

Its best to avoid upgrading this building by colonising well and aquiring large planets in the first place, as the cost can become quite large.
