Pianka began his speech by condemning anthropocentrism, or the idea that the human race occupies a privileged position in nature. He exclaimed, "We're no better than bacteria!"
He argued that the sharp increase in the human population since the onset of industrialisation was destroying the planet. He warned that Earth would not survive unless its human population was reduced to a tenth of its present number.
AIDS took too long to kill people off, he explained. His preferred method of exterminating over five billion human beings was via airborne Ebola (Ebola Reston), because it is both highly lethal and kills its victims in days rather than years
However, as Mim observed: "Professor Pianka did not mention that Ebola victims die a slow and torturous death as the virus initiates a cascade of biological calamities inside the victim that eventually liquefy the internal organs.
"After praising the Ebola virus for its efficiency at killing, Pianka paused, leaned over the lectern, looked at us and carefully said, 'We've got airborne 90 percent mortality in humans. Killing humans. Think about that.' "
After he finished his address, the audience burst into applause.
