CO2 Drawdown - Where Should the Water Go?

Does plant growth or soil formation drawdown the most CO2? Learn about the critical zone and the ideal distribution of water between plants and soil in this episode of GeoNews. Understanding the processes and interactions in this zone helps us to better understand earth's climate, agriculture, and water resources.
