You're ok as long as you don't burn it. Once you do, it's a renewable resource- you just need to produce more than you burn and figure a way to store it. I guess there are some hydride deposits on ocean floors that have methane locked up. Very unstable from what I hear, the bane of offshore drillers.

In thinking a bit further- two limitations would be water and basic nutrients, ie N/P/K. N is readily available, and algae that lives in brine water exists. Water losses would be primarily evaporation.

Even if you inject co2, eventually it's going to work it's way back into the system as one form of carbon or another. What you really need is a catalyst that converts the gas into a semi-solid, in reversable fashion, as we may need that carbon at some point in the future.
