Nobody is making or destroying carbon.
Who cares if it's "fossil carbon"? Carbon from a dead tree (or animal) that has fallen and is rotting on the forest floor is in no way different from carbon trapped in a pool of goo deep within the earth which began as a tree (or animal) that fell and died a million years ago.
There are two carbon cycles. The atmosphere-lithosphere quick turn-around one, and the larger much slower one which includes that plus the crust and upper mantle.
Time scales and orders of magnitude matter. In the last 200 years we've increased the amount of atmospheric carbon by about 40% and the acidity of the ocean by about 30%. In 100 million years time the carbon cycle will be back in balance, but in 500 years it will be experiencing a major wobble. That major wobble may cause enough problems to destroy our civilization one way or another. Let's avoid that, eh?
It's not about saving the Earth, the Earth will be just fine. It's about saving our civilization and a large percentage of the species on the planet.
Good grief! It starts to appear than nobody is getting even a basic education anymore in REAL subjects and that many are instead being indoctrinated into brain-dead political ideologies.
I can tell you about subduction and the major forms of carbon-silicates in the Earth's mantle if you want me to, but I'm guessing you don't.
