[Terrapreta] CO2 rising

[lou gold]

Yep, living sinks do seems as sort of steady-state recyclers. They give and
take because they are alive. So if sinks mean removal of carbon relatively
permanently, they don't exist simply because life is not permanent.

I believe intuitively that charcoal is the way to create more "sunk" carbon.
But to truly repair past damage it needs to be linked to growing fuel rather
than mining it because mining keeps adding to the total volume of the active
carbon pool which needs to reduced.
