In this week's interview, Chief Correspondent Steve Scher talks with biologist Samuel Wasser about the illegal ivory trade and the threat it poses to the endangered elephant population. Wasser outlines scientific tools being developed to track poachers and determine the locations and regions where they're getting their ivory. They discuss the tactics used for combating poachers, such as reducing demand for ivory and tracking the locations of ivory supplies before they've been confiscated or shipped. Wasser expresses his faith in the diversity of people's interests, and the need for everyone to pursue those interests in order to combat the innumerable issues of the world—everything from ivory poaching to cancer to climate change.
