Asteroid, robots & viruses 'could kill millions'

The rise of robots and deadly viruses are among the threats that could wipe out swathes of humanity - but governments are failing to prepare properly for them, a new report warns. Catastrophic climate change, nuclear war and natural disasters such as super volcanoes and asteroids could also pose a deadly risk to mankind, researchers said. It may sound like the stuff of sci-fi films, but experts said these apocalyptic threats are more likely than many realise. The report Global Catastrophic Risks, compiled by a team from Oxford University, the Global Challenges Foundation and the Global Priorities Project, ranks dangers that could wipe out 10% or more of the human population. It warns that while most generations never experience a catastrophe, they are far from fanciful, as the bouts of plague and the 1918 Spanish flu that wiped out millions illustrated.
