Addressing the Threat to Earth System Boundaries - Earth Commission, the prestigious international group of scientists, recently published a study that is receiving a great deal of attention. The study in Nature Journal indicates that we have now breached most of the Earth system boundaries that include climate, biodiversity, fresh water, soil and air. Millions of people have already been displaced, worldwide health is threatened, extinctions are accelerating, ecosystems are being destroyed. The authors emphasize two things: (1) that urgent action is required to save the planet; and (2) action must include justice for the masses who are suffering the results of global destruction. Guest: Diana Liverman, Ph.D., Regents Professor, University of Arizona, School of Geography, Development and Environment; Commissioner, Earth Commission: Global Commons Alliance.
