Editing CO2

'''CO<sub>2</sub>''', also called carbon dioxide, is a grey gas which is transportable via [[pipe]]s. It is produced when the [[population]] consumes [[oxygen]] in the [[atmosphere]].

CO<sub>2</sub> is a danger to the population, atmospheric concentrations of 10% or more CO<sub>2</sub> cause suffocation if the crew is not in [[spacesuit]]s, and can suffocate passengers. The atmosphere must be rich in oxygen and poor in CO2 for long term survival. 

CO<sub>2</sub> can be removed from the atmosphere using [[CO2 Scrubber|CO2 scrubbers]]. CO<sub>2</sub> can be reprocessed into oxygen using an [[Air Reprocessor|air reprocessor]].
