We have all been taught in school about the natural cycles of the earth.
For example, water evaporates from the oceans, comes down as rain, form rivers and drains back into the ocean. It's a cycle.
Oxygen is breathed in by animals, combined with carbon and released as carbon dioxide back into the air, where plants release the oxygen back for us to breath and use the carbon to grow. It's a cycle.
And, of course, carbon has it's own cycle where we eat the plants and then release the carbon back into the air when we breath.
All this is necessary for the happy balance of plant and animal life on earth.
Water cycles. Oxygen cycles. Carbon cycles. But... the carbon cycle has a major problem the others don't. Carbon is absorbed by plants which die and then become buried, or in the case of the oceans, buried on the ocean floor, forever. (This is called carbon sequestration)
The only natural source that exists to replenish the lost carbon is volcanoes. They do not produce nearly enough to replenish the sequestered carbon.
What does this mean? It means that due to the constant loss of carbon from the atmosphere over the last millenia that the last few hundred years before industrialization has seen the lowest levels of carbon (in the form of CO2) that the earth has ever experienced in its history.
Plant and animal life on this planet that happily evolved with high levels of CO2 are starving from a lack of it. (Interestingly, this is evidenced by the fact that greenhouse plant growers add extra CO2 to the greenhouse air to achieve the proper balance.)
It means there is no natural way for it to be replenished. Without human intervention it would continue toward zero and the earth eventually will be nearly completely starved of carbon.
WHAT CAN WE DO?
We are already doing it. We learned in school that fossil fuels come from long-dead plants (fossils). Unwittingly, humans are mining this long lost carbon in the form of fossil fuels and releasing it back into the atmosphere.
We are not home yet. We have only succeeded in increasing the CO2 levels from their lowest ever (around 300 ppm) to roughly 400 ppm. At the current (2011) rate of increase of around 6 to 7 ppm/year, it will take another 60 years before we get CO2 level back to a natural level where plant life will flourish at 800 ppm (or more).
(Before the CO2 kooks get you all jumpy over this seemingly huge increase, keep in mind that this amount would only mean a 0.00002% decrease in the oxygen we breathe. An completely negligable amount of no consequence.)
SPREAD THE WORD
Stop fighting against the CO2 zealots who believe, for various reasons, that we are producing man-made global warming. Their ignorance can't be helped. Just tell them "it's the sun, stupid" and move on.
As for the rest of your friends, start fighting for the continued replenishment of atmospheric carbon to help restore the natural balance.
Educate others in the battle against Global Carbon Starvation which has occurred and which we are just now beginning to understand and help reverse the effects.
MORE INFORMATION - THE PETITION PROJECT
This is not mine but it is definitive argument against the CO2 kooks. It is supported by tens of thousands of scientists and PhDs. Sadly though it does not go far enough to actually support the need for atmospheric carbon be replenished. But it is a start.
