The ice age that killed off the dinosaurs was not caused by the dinosaurs or man.
Man is not killing the climate now.
BTW, we ARE facing a mass extinction bigger than the toll of all the wars in the 20th century. The numbers dead from abortion alone put us there. Add in those who's conception was halted by The Pill and the tally is hundreds of millions (possibly billions). And that IS a man-made act.
Over a hundred million dead from Communism as well. Another man-made act.
Some scholars have estimated that between the time when Josef Stalin ruled the Soviet Union between 1928 and 1953 and when Mao Zedong ruled China between 1949 and 1976, the death toll from a combination of mass shootings, labor camps, forced exile, and ill-advised economic policies could be as high as 150 MILLION. That's fifteen times what the Nazis achieved with the Final Solution (die Endlösung).
