A World Without Soil

Participants in this session will learn why soil is an essential part of the Earth’s ability to feed the world's population and it is key to climate stability. Ninety-five percent of our food supply is dependent upon soil. More than three-quarters of the antibiotics used in the clinical medicine are derived from soil bacteria. And soil stores three to four times as much carbon as the entire atmosphere. Despite the importance of soil to human survival and the health of the Earth, we are letting it slip away. Soil erosion exceeds the rate of soil genesis by at least 10-fold. This talk will explore the forces that are eroding soil and what we can do to save it.
