Sometimes the Earth bites. Some would say ‘sometimes the Earth bites back,’ with climate change and rising incidents of flooding in mind. But most natural disasters are not man-made. There’s very little we can do at the moment about earthquakes and volcanoes, for example. And hurricanes and typhoons were around long before we started filling the atmosphere with CO2. So studying natural disasters and preparing for them shouldn’t be undertaken with a sense of guilt about self-inflicted damage. It should be done with a simple sense of self-preservation.
