Soil scientists maintain that a mere 2 percent increase in the carbon content of the planet’s soils could offset 100 percent of all greenhouse gas emissions going into the atmosphere. But how could this be accomplished? What would it cost? Is it even possible?
Yes, says author Courtney White, it is not only possible, but essential for the long- term health and sustainability of our environment and our economy.
Right now, the only possibility of large-scale removal of greenhouse gases from the atmosphere is through plant photosynthesis and related land-based carbon sequestration activities. These include a range of already existing, low- tech, and proven practices: composting, no-till farming, climate-friendly livestock practices, conserving natural habitat, restoring degraded watersheds and rangelands, increasing biodiversity, and producing local food.
In Grass, Soil, Hope, the author shows how all these practical strategies can be bundled together into an economic and ecological whole, with the aim of reducing atmospheric CO2 while producing substantial co- benefits for all living things. Soil is a huge natural sink for carbon dioxide. If we can draw increasing amounts carbon out of the atmosphere and store it safely in the soil then we can significantly address all the multiple challenges that now appear so intractable.
