Coruscant Atmospheric Reclamation Project
this was the name of the first set of planet-wide atmospheric scrubbing systems developed by the Old Republic, in an effort to ensure that Coruscant's atmosphere did not become laden with toxic gases. The project was required because there was no arable land left on the planet, and all plantlife which would have helped maintain the air quality was eliminated. Many of the stations employed specially-developed organisms - often referred to as devourer organisms - to literally consume the toxic gases and chemicals from the planet's air.
