This National Geographic/PBS 4-part series examines four topics in current Earth science: invasive species, water quality, global warming, and loss of predators. The series examines case studies by presenting evidence as "clues" scientists are finding, and discusses work being done to "solve" these mysteries and remedy the problems. There are four episodes (one hour each) which include online teachers' guides and episode guides to utilize parts or whole episodes in class. Interactive information about choices individuals can make that can have an affect on each of these issues are also included. Episodes (in DVD format) are available on the site.
