A few weeks ago I finished reading A Short History of Nearly Everything, by Bill Bryson, but I hadn't gotten around to writing about it yet. I I must say I thoroughly enjoyed it, and read through it in a few days because I just couldn't put it down.
In short, the book is a history of Earth, the Universe and Everything, but told by telling the history of the scientists who figured it all out. Some of them were quite eccentric indeed. I don't remember which one it was, but there was a story about a chemistry researcher in there somewhere who insisted on tasting every substance he did experiments with. He was found dead one day in his lab among a dozen poisonous substances...
Another one had the crazy idea he would eat as many species of animal as possible: eating through the animal kindom, as it were. Yet another story is about the adventures of several teams of scientists traveling all over the world for many long years in order to observe the transit of Venus in front of the Sun from various locations, only to be marred by clouds at the last instant, or to be attacked by angry locals.
But the tales of eccenticity weren't the only thing that made me love this book. After reading it you realise just how lucky we are as human race to have come about at all. Our very existence depends on so many accidents and coincidents that it isn't even funny anymore. If the asteroid that killed the dinosaurs had missed, if the moon hadn't been caught in Earth's gravity, if the Ice Ages had lasted a little longer or shorter, if this monkey hadn't made love to that one... no human race.
In fact, if you look at the timeline of Earth's history, we literally arrived at the last instant: hundreds of thousands, if not millions of species have come before us, flourished and gone extinct. Disasters of epic proportions wiped away large parts of the world, only to see them replaced again by strange, new life-forms.
Asteroid impacts, volcanic eruptions, earthquakes, cosmic radiation, solar fluctuations, shifts in the rotation of the Earth or of the magnetic field... if you look at it, there are many, many ways in which the human race can be wiped out or put back in the stone age, in a much shorter time than it took us to get from there to where we are now. As an example, watch the recent BBC 'fictional documentary' about the supervolcano beneath Yellowstone Park in the U.S. going off...
All of this made me wonder: if there are so many potential disasters we can't do a thing about, why aren't we spending some of that Kyoto money instead on strategies to make sure we survive these things, possibly by getting the hell off this planet?
