Humans to go extinct in 100 years, scientist predicts
By Sebastian Loh, 6/29/2010
PhysOrg.com, an online science news service, reports that distinguished Australian scientist Professor Frank Fenner has predicted that humanity would likely meet its end within a century.
Fenner cited overpopulation, environmental destruction and climate change as the primary factors which will drive mankind into extinction.
Professor Fenner's voice is important and well-regarded because of his instrumental role in the global eradication of smallpox. He has had a life-long interest in environmental issues, and is a recipient of many illustrious awards, including the WHO (World Health Organization) medal.
Perhaps infinitely more worrisome is Fenner's confidence that the situation is irreversible. While there are currently efforts to grapple with those issues, he asserted that we are beyond the point of no-return due to the magnitude of these effects we have had on Earth since the Industrial Age. He said they have come to rival the impact of ice ages or comet crashes.
The professor noted that while climate change is only at its infancy, it will probably be the force behind our extinction. He also predicted that Earth's ever-increasing population will result in more violent conflicts over food and other resources.
