The problem with the carbon-in-soils equation from a human perspective is that we didn't evolve on this planet in an ecosystem where all that carbon was held in the soil. All that carbon was locked up deep down in the rock. For tens to hundreds of millions of years.
In the course of little more than 150 years, we have lifted it out of the earth's crust and put it into the atmosphere.
