Eventually decay or fire will breakdown the sequestored carbon as CO2
again.

Ok Lion, then it appears that the carbon cycle and carbon sequestering
both function optimally as per natures years of trial and error, this
trial and error allowing for the flourishing of multicellular
life....IOW, nature knows what she is doing.

All the best.
