Two world wars. The election of many truly international politicians in hundreds of different countries. The slow changing of the global environment. The depletion of world resources and the invention of the Atomic bomb. Man made it into space, and onto the moon. Billions died, and billions were born, some died of old age, many didn't. The formation of the U.N, and the E.U. The eventual rise of the Asian states, along with a steady increase in global domestic product. A new millenia has passed, and numerous apocalyptic conspiracy theories have been debunked. The rise of the personal computer and of the internet. Eventually the arrival of WikiAnswers, and the formation of this rather generalised question; and a billion other events.
