Darn public radio!  As I tooled along in the Miata toward Peggy’s Cove I listened to public radio.  The science segment introduced me to the concept of a new geological epoch, the anthropocene.  Epochs, it seems, are individually started and ended based on some unique fingerprint in the geology of the planet.  Has mankind acted in a way that will be evident in the geology of the planet millions of years from now?  If so, we get an epoch of our own and we might call it the anthropocene.   Seems the answer is yes and that the tell tale fingerprint is carbon dioxide from burning fossil fuels and the mass extinctions that it is bringing about.  Geeze, one more angle of science telling us we are messing this beautiful place up.  Suppose we can get our shit together and leave fewer fingerprints?
