Who's up for a little hysteria about overpopulation?

Frank Fenner is a professor at the Australian National University and one of the scientists who helped eradicate smallpox.

He has claimed that the human race will be unable to survive a population explosion and ‘unbridled consumption.’

Fenner told The Australian newspaper that ‘homo sapiens will become extinct, perhaps within 100 years.’

‘A lot of other animals will, too,’ he added.
