"CO2 plays a critical role in maintaining the balance in Earth's atmosphere and the air we breathe."

I think that the following sentence is an example of parallel structure.

Now, I want to know that which part participates in balancing. 1 or 2?

"CO2 plays a critical role in maintaining the balance in Earth's atmosphere and the air we breathe."



1 "CO2 plays a critical role in maintaining the balance in Earth's atmosphere and (maintaining the balance in) the air we breathe."


2 "CO2 plays a critical role in maintaining the balance in Earth's atmosphere and (a critical role in)the air we breathe."

" If you say "the balance between", I read this: CO2 has a role. The role can maintain the balance. The balance is present between the atmosphere and the air.
