Dennis Wingo returned to The Space Show to discuss his new book, "Moonrush: Improving Life on Earth with the Moon's Resources." Mr. Wingo shows how the Moon's resources can be used to solve energy problems here on Earth. During this thorough discussion, Mr. Wingo was asked about the ethics, environment, and "common heritage for mankind" issues pertaining to lunar economic development. Together with Dennis Wingo, we provided listeners a unique point of view, pointing out that the ethical course is to develop the resources and bring the resulting advantages to the people here on Earth.
