“Extinction is the rule. Survival is the exception”.
“The Cretaceous extinctions thus seem to have a cause very similar to the possible consequences of modern warfare known as Nuclear Winter. Through dust excavated by nuclear ground bursts, and smoke from the burning of “strategic targets”, in and around cities, we humans can generate our own climatic catastrophe, perhaps adequate to bring about massive extinctions in our age as in the Cretaceous. The principle difference is that the dinosaurs did not contrive their own extinction.”
