Greenhouse gases:

"Greenhouse gases are gases in an atmosphere that absorb and emit radiation within
the thermal infrared range. This process is the fundamental cause of the greenhouse
effect.[1] The main greenhouse gases in the Earth's atmosphere are water vapor,
carbon dioxide, methane, nitrous oxide, and ozone.
... "
- http://en.wikipedia.org/wiki/Greenhouse_gas

- "Water vapor accounts for the largest percentage of the greenhouse effect, between
36% and 66% for water vapor alone, and between 66% and 85% when factoring in clouds."
- ibid.

... but do not be deluded to suppose that "water vapor" comprises 36 to 66 percent of the atmosphere.

While water vapor remains more or less constant, Carbon Dioxide, which makes up less than one tenth of one percent of Earth's atmosphere (considered a trace gas currently occurring at an average concentration of about 383 parts per million by volume or 582 parts per million by mass.), has no liquid state, accumulates from "overproduction" by man, and / or by volcanoes, until it is absorbed, during photosynthesis, or into seawater; ie. "carbon sink" [http://en.wikipedia.org/wiki/Carbon_sink].

Carbon Dioxide "concentration varies seasonally (see graph at right) and also consi-
derably on a regional basis, especially near the ground. In urban areas concentrations
are generally higher and indoors they can reach 10 times background levels."
- ibid.

Attempts to scare "public awareness" come through use of statistics (omitting other statistics), such as:

"The total mass of atmospheric carbon dioxide is ... 3,000 gigatonnes"

"The [earth] atmosphere has a mass of about five quintillion (5x1018) kg"
- http://en.wikipedia.org/wiki/Atmosphere_of_Earth

Someone want to convert that to "gigatonnes" ... ?

"Dry air contains roughly (by volume) 78.08% nitrogen, 20.95% oxygen, 0.93% argon,
0.038% carbon dioxide, and trace amounts of other gases. Air also contains a variable
amount of water vapor, on average around 1%.

So oxygen - also a "greenhouse gas" - is almost a thousand times more prevalent in Earth's atmosphere.

Is there an economic advantage to outlawing oxygen ?

... or maybe I should not ask.
