It is a new age of geological time or so some say called the Anthropocene Epoch. This is noted in the in the journal Environmental Science & Technology. (web issue March 29; print issue April 1). This is because of the dramatic recent or potential changes in the world such as climate warming and species extinction. The dawning of this new epoch may include the sixth largest mass extinction in the Earth’s history. Whether the new era will be dramatic as the Jurassic with the end of the dinosaur is still to be determined.
