Living on a Quagmire Planet: This Could Get a Lot Uglier
Sixty-six million years ago, so the scientists tell us, an asteroid slammed into this planet. Landing on what’s now Mexico’s Yucatán Peninsula, it gouged out a crater 150 kilometers wide and put so much soot and sulfur into the atmosphere that it created what was essentially a prolonged “nuclear winter.” During that time, among so many other species, large and small, the dinosaurs went down for the count. (Don’t, however, tell that to your local chicken, the closest living relative — it’s now believed — of Tyrannosaurus Rex.)
It took approximately 66 million years for humanity to evolve from lowly surviving mammals and, over the course of a recent century or two, teach itself how to replicate the remarkable destructive power of that long-gone asteroid in two different ways: via nuclear power and the burning of fossil fuels. And if that isn’t an accomplishment for the species that likes to bill itself as the most intelligent ever to inhabit this planet, what is?
Talking about accomplishments: as humanity has armed itself ever more lethally, it has also transformed itself into the local equivalent of so many asteroids. Think, for instance, of that moment in the spring of 2003 when George W. Bush, Dick Cheney, and crew launched the invasion of Iraq with dreams of setting up a Pax Americana across the Greater Middle East and beyond. By the time U.S. troops entered Baghdad, the burning and looting of the Iraqi capital had already begun, leaving the National Museum of Iraq trashed (gone were the tablets on which Hammurabi first had a code of laws inscribed) and the National Library of Baghdad, with its tens of thousands of ancient manuscripts, in flames. (No such “asteroid” had hit that city since 1258, when Mongol warriors sacked it, destroying its many libraries and reputedly leaving the Tigris River running “black with ink” and red with blood.)
