atmosphere via photosynthesis into carbon bearing materials. Most is returned
to the atmosphere as carbon dioxide through consumption by plants themselves
and various animals from microbes to elephants - and burning of plant materials.
about 24 billion tonnes of this cycle by my estimate. Emissions from fossil
fuel are about 8 billion tonnes. This simple analysis suggests the potential
is there to counter fossil fuel emissions through conversion of plant
material to charcoal.
|Could we modify
agricultural techniques to ensure a much larger portion of carbon is retained
in the soil?
specifically, could we convert a
portion of the plant growth we manage to charcoal and place it in the soil to
serve as a carbon sink and a soil enhancer?
