Terra Sapiens: The Human Chapter in the History of Earth
Dr. David Grinspoon, Library of Congress
Considering that Earth’s history extends back more than four billion years, our species is an absolute newcomer, though one with significant impact. Dr. Grinspoon will discuss the
current human-dominated phase of our planet¹s life in a broader context; juxtaposed against previous geological eras in Earth¹s history, as well as what¹s known from studying changes on other planets. The goal is to better understand the essence of our current moment in geological time and what it means for intelligent life in the universe and for the future of our civilization.
Host: Dr. Frank Summers
