It's not _that_ inert. N2 is always being removed from the atmosphere by
various nitrogen fixation processes. Other processes are converting
nitrates to free N2. Nitrogen, oxygen, and CO2 are at their present
concentrations because they are maintained there by active processes,
both biological and geological.
