Professors David Beerling and Noah Planavsky are both experts in the innovative practice of "enhanced rock weathering," which crushes rocks such as basalt and applies the powder to soil as a way of improving the quality of the soil and also capturing carbon dioxide from the atmosphere and sequestering it. Planavsky is not only a computer modeler but also the founder of a company that farmers hire to apply this technology. We consider the financial implications of using this innovation widely.
