Mark Sagoff is a director of philosophy and public policy at the Univerity of Maryland. Sagoff discusses the economic decisions we make about the environment. He believes people dont place any value on things like "open space, a stand of trees or an unspoiled landscape," he puts this into perspective by asking his audience, "how much did you spend last year to preserve open space? How much for pizza and gas?" (167, Easton)
Sagoff believes it is impossible to place economic value on things the provide aesthetic satisfaction and value can be determined only by what people are willing to pay. Envrionmental problems are difficult to assess and require much more then an economic analysis.
