It is too easy to look with just the eyes and assume that trees are all there is to capture carbon. But the biomass under the ground is double that above ground. Regreening damaged lands sets the conditions for soil life to flourish and thereby necessarily sequesters carbon. Moreover, by tackling this one problem, we also create fertile soils, provide materials for human needs, and stop erosion.
