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 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.
