This week's question concerns the world-renowned Australian scientist Professor Frank Fenner - who helped to wipe out smallpox - and his prediction that humans will probably be extinct within 100 years. His reasoning includes overpopulation, environmental destruction, and climate change. Fenner stated that homo sapiens will not be able to survive the population explosion and "unbridled consumption," and will become extinct, perhaps within a century, along with many other species.
What do you think? Will humans be extinct in 100 years?
