Protect biodiversity hot spots and the rest will follow

Edward O. Wilson of Harvard University has written and lectured widely in fields ranging from sociobiology and evolutionary psychology to conservation biology. He spoke recently on “sustainability” at Baldwin-Wallace College in Berea, Ohio. Wilson believes that too much emphasis has been placed on trying to reduce energy consumption and avert climate change—what he calls the “physical environment”—and too little on preserving habitat and biodiversity, or the “living environment.”
