3. How does this relate to APES?
•Although Ehrlich was not the first to raise the alarm about population issues – concern had been widespread in the 1950s and 1960s – his charismatic and media-savvy approach brought the issue to a new level of media prominence.
•As of 2013, Ehrlich continues to perform policy research concerning population and resource issues, with an emphasis upon endangered species, cultural evolution, environmental ethics, and the preservation of genetic resources. All of these topics are central to the curriculum of APES.
