If the CO2 in the atmosphere is building (for what ever reason, don't

falling at the same rate? Should we not be overly worried about
reducing O2 rather than increasing CO2?
Does anyone here know of any research and/or results for this
happenning?

Most of the world's oxygen is in the ground as oxides and suphates
etc. This can be released by microbes and plants
