Thanks for this thread.
CHON is found in all life thanks to the magic process of photosynthesis.
Without CO2 supplying the C there would be no life on Earth.
Since CO2 is essential to all life, it is an environmentally friendly gas.
If fact, CO2 is the “Greenest” of all green house gasses.
BTW, since the EPA banned CO2, is the EPA a Totalitarian Front Organization which opposed to Life?
