New epoch in geologic time: Anthropocene

Earth and its epochs extend so far back in time that it is beyond comprehension.  I recently came across a  TED post that talks about a movement afoot among  geologists and other scientists to identify a new Epoch in Earth’s geology marked by the impact of man.  It would be called the Anthropocene.  I highly recommend that you take a look at this fascinating and readable article by David Biello, an award winning journalist and science curator for TED. He has a new book, coming out in November,”The Unnatural World,” which discusses Anthropocene.

To set the stage I have gathered some background tidbits:

  • Earth is about 4.54 billion years old;
  • If introduced, Anthropocene would end the Holocene Epoch which began 11,700 years ago;
  • Holocene began after the Ice Age.  The Ice Age extended from 110,000 years ago to 12,000 years ago;
  • The timing of the new Epoch is still being debated, but there is strong support for 1950, as the time when significant changes in air, soil, water, and rocks (caused by human activity) could first be identified.

…the point of naming the Anthropocene is not to memorialize humanity in the rock record. The point of the Anthropocene [‘new age of man’] is to recognize people’s world-changing impacts in the hopes of persuading us to take a slightly less anthropocentric approach. People need to make room for plants and animals if we want to avoid another mass extinction…. The world’s pollution problems have to be addressed together, or they won’t be solved at all.

In short, the point of an Anthropocene is to prove that humanity is actually not like a glacier or an asteroid. We can choose to do better…
