Episode 151: What if we could heal broken ecosystems, toxic landscapes, and poisoned water?  My guest today is Dr. John Todd, ecological designer and author of the new book, Healing Earth- An Ecologist's Journey of Innovation and Environmental Stewardship.  John Todd boldly travels to places that others try to avoid: toxic waste sites, oil spills, leaking landfills, and damaged waterways. Using the tools of nature to remediate these areas, John and his colleagues do good things in bad places. An expert in the design and construction of wastewater treatment systems, Eco-Machines, and living technologies, John's projects pair ecological knowledge with biological allies, like bacteria, fungi, and plants.  An internationally renowned inventor and visionary, John's new book offers us a map of how to heal the Earth's damaged places, and in so doing, find the great work of our time.
