Forrest Mims of the Texas Academy of Science has a somewhat disturbing report on a speech one Eric Pianka, a "University of Texas evolutionary ecologist and lizard expert," delivered to the academy last month. Pinaka argued that "overpopulation" was endangering the Earth, a commonplace enough notion, but one he carried to monstrous extremes:

"Without presenting any data to justify this number, he asserted that the only feasible solution to saving the Earth is to reduce the population to 10 percent of the present number. . . .
His favorite candidate for eliminating 90 percent of the world's population is airborne Ebola (Ebola Reston), because it is both highly lethal and it kills in days, instead of years. However, 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. . . .
When Pianka finished his remarks, the audience applauded. It wasn't merely a smattering of polite clapping that audiences diplomatically reserve for poor or boring speakers. It was a loud, vigorous and enthusiastic applause.
Then came the question and answer session, in which Professor Pianka stated that other diseases are also efficient killers.
The audience laughed when he said, "You know, the bird flu's good, too." They laughed again when he proposed, with a discernable note of glee in his voice that, "We need to sterilize everybody on the Earth." . . .
He spoke glowingly of the police state in China that enforces their one-child policy. He said, "Smarter people have fewer kids." He said those who don't have a conscience about the Earth will inherit the Earth, "...because those who care make fewer babies and those that didn't care made more babies." He said we will evolve as uncaring people, and "I think IQs are falling for the same reason, too."
With this, the questioning was over. Immediately almost every scientist, professor and college student present stood to their feet and vigorously applauded the man who had enthusiastically endorsed the elimination of 90 percent of the human population."
