So with all of this taken into account, what are your odds of dying in an asteroid strike in any given year? About 1-in-70,000,000.
So all-in-all I can assume I personally die from an asteroid strike about three times in 200M years while ignoring that the entire human species is wiped out twice.
And if I wanted the US Department of Transportation to handle this, based on personal risk to individual US citizens alone, they could spend about $30M a year on asteroid prevention.
The article sucks. It just says the risk is low and makes no attempt to compare the risk or the cost to anything else.
