We have ppm of all atmospheric gasses in the air we breathe. The 300-400ppm referenced above are probably numbers for co2 in a clean outside environment. There is also some number/ppm for oxygen, nitrogen, and all those other gasses . . .

That would be interesting to find the total ppm of every gas which we breath and see how it coinsides with plant ppm feeding levels. I did a quick search and came up with nothing.
