60,000,000 dead in next impact mega-tsunami
in the recent past, around 1 per 1,000 years -
that's 60,000 per year annualized. or about 167 per day, if you want to look at it that way.
NASA isn't even funding sufficient crater counts to try and get a really good handle on how bad this problem is - instead they make up numbers based on studies from the 1960's and some really bad theory, and then suppress discussion of mitigation.
in the recent past, we've had tunguska class events about 1 per 100 years -
most recently they have hit in unpopulated areas -
take a country, any country, and imagine the world without it.
One thing is certain, there won't be much discussion about the need the day after the next one hits -
