Soon thereafter, McHarg began teaching at the University of Pennsylvania, where he developed the department of landscape architecture, and developed a popular new course, titled "Man and Environment" in 1957. The course featured leading scholars whom McHarg invited to his class to discuss ethics and values, as well as other ideas ranging from entropy to plate tectonics. In 1960, he hosted his own television show on CBS, "The House We Live In", inviting prominent theologians and scientists of the day to discuss the human place in the world, in a style similar to the one he honed teaching "Man and Environment."
