So, with biochar we use a means, cheap and readily available in every climate, to take carbon from the air and use it to rebuild the soils we have degraded, so increasing the water retention, reducing the risk of floods and increasing crop yields for all farmers.
We reduce the soot and carbon dioxide emissions from burning wood fuel, also make trees more valuable, so farmers will want to plant more, so fixing more carbon and reforesting slopes that have been deforested.
My feeling is that when you do the right thing you discover more and more ways in which it is the right thing. Not just another technique, but a whole process of reversing what we have been doing to the surface of the earth.
