Excuse the french, but how the phuk is Carbon a polutant. Its the 4th most abundant element in the universe.
Carbon /ˈkɑrbən/ (from Latin: carbo "coal") is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. There are three naturally occurring isotopes, with 12C and 13C being stable, while 14C is radioactive, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity.
There are several allotropes of carbon of which the best known are graphite, diamond, and amorphous carbon. The physical properties of carbon vary widely with the allotropic form. For example, diamond is highly transparent, while graphite is opaque and black. Diamond is among the hardest materials known, while graphite is soft enough to form a streak on paper (hence its name, from the Greek word "to write"). Diamond has a very low electrical conductivity, while graphite is a very good conductor. Under normal conditions, diamond has the highest thermal conductivity of all known materials.
All carbon allotropes are solids under normal conditions with graphite being the most thermodynamically stable form. They are chemically resistant and require high temperature to react even with oxygen. The most common oxidation state of carbon in inorganic compounds is +4, while +2 is found in carbon monoxide and other transition metal carbonyl complexes. The largest sources of inorganic carbon are limestones, dolomites and carbon dioxide, but significant quantities occur in organic deposits of coal, peat, oil and methane clathrates. Carbon forms more compounds than any other element, with almost ten million pure organic compounds described to date, which in turn are a tiny fraction of such compounds that are theoretically possible under standard conditions.
Carbon is the 15th most abundant element in the Earth's crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. It is present in all known life forms, and in the human body carbon is the second most abundant element by mass (about 18.5%) after oxygen. This abundance, together with the unique diversity of organic compounds and their unusual polymer-forming ability at the temperatures commonly encountered on Earth, make this element the chemical basis of all known life.
From an article by Indur M. Goklany PhD
"This illustration from a recent article in Science magazine shows that CO2 is plant food. It is based on both empirical data and model results (not “data”). I know that looking at empirical data might seem like a novel idea to some people, but for some perverse reason, I find it more compelling.
On the right: Empirical Data. Growth of 21-day-old rice and S. viridis seedlings at different ambient CO2 concentrations ranging from 30 to 800 parts per million. NOTE: The very last set of pots on the extreme right is out of sequence. They are for 390 ppm, while the next to last pots are for 800 ppm."

Carbon dioxide in earth's atmosphere is considered a trace gas currently occurring at an average concentration of about 390 parts per million by volume or 591 parts per million by mass. [from:Wikipedia]
The problem is that that Carbon Dioxide is now invariably shortened to Carbon in every reference involving global warming. This is convenient for the for propaganda purposes as the word Carbon is invariably associated with pollution, smoke, soot, blackened ashes and all things dirty. So terms 'reduced Carbon' or 'high Carbon' or 'low Carbon' all imply greater or lesser amounts of dirty black stuff.
The fact that they're actually referring to Carbon Dioxide which isn't black and dirty and is vital for life on this Earth is not a convenient truth. So it's reduced to Carbon. Just another example of the attempt to brainwash the public at large.
I stopped using carbons about 30 years ago, must have been about the time photocopiers were invented. But really can't see the problem, sure they were messy to use, but disposed of in the WPB they never made trouble.
