Suppose you attend a town meeting at which some experts tell the audience that they have performed a cost-benefit analysis of a proposed transit system that would probably reduce overall air pollution and fossil fuel consumption. The analysis, however, reveals that ticket prices will not cover the cost of operating the system when fuel, wages, and equipment are taken into account. As a biologist, you know that if ecosystem services had been included in the analysis, the experts might have arrived at a different answer. Why are ecosystem services rarely included in economic analyses?

  3. Ecosystem services only take into account abiotic factors that affect local environments.
  4. Their cost is difficult to estimate, and people take them for granted.

In a report by ABC News, the headlines read “City Living Increases Men’s Death Risk” The headlines were based on a study of 3,617 adults who lived in the United States and were more than 25 years old. One researcher said, “Elevated levels of tumor deaths suggest the influence of physical, chemical and biological exposures in urban areas... Living in cities also involves potentially stressful levels of noise, sensory stimulation and overload, interpersonal relations and conflict, and vigilance against hazards ranging from crime to accidents.” Is a conclusion that living in an urban environment causes an increased risk of death justified?
