“…The chance in your lifetime of an even bigger asteroid impact on Earth {than Tunguska in 1908}—with explosive energy of 100 megatons of TNT— is about 1%. Such an impact would deliver many times the explosive energy of all the munitions used in World War II, including the atomic bombs. This risk to humanity is similar to an individual’s odds of dying in a car accident. That risk is small, but would you drive a car without air bags and seat belts? The question is apt because our society is effectively doing so with regard to the risk of a devastating asteroid strike.”

Finally, some concerned souls are proposing we establish a Space Guard. Cool – I’d totally join up. 1
