Biological carbon sequestration is the long-term storage of carbon in soils and vegetation resulting from applications of compost and mulch to land. Soils hold more carbon than the atmosphere or plant and animal life combined. Climate experts say no strategy to reduce climate change is complete without using the vast carbon sinks available in the world’s soils. Over the centuries, human activities have degraded soil, resulting in the loss of a significant portion of their carbon content to the air. Graphic credit: Cal Recycle
