End of Civilization
An impact event is commonly seen as a scenario that would bring about the end of civilization. In 2000, Discover Magazine published a list of 20 possible sudden doomsday scenarios with impact event listed as the No. 1 most likely to occur. Until the 1980s this idea was not taken seriously, but opinions changed following the discovery of the Chicxulub Crater, which was further reinforced by witness to the Comet Shoemaker-Levy 9 event.

Famous quotes containing the word civilization:
“We shall make mistakes, but they must never be mistakes which result from faintness of heart or abandonment of moral principles. I remember that my old school master Dr. Peabody said in days that seemed to us then to be secure and untroubled, he said things in life will not always run smoothly, sometimes we will be rising toward the heights and all will seem to reverse itself and start downward. The great thing to remember is that the trend of civilization itself is forever upward.”
—Franklin D. Roosevelt (1882–1945)
