Gaia Theory, “Irresponsible Heroes”, & Why We’re Like Cyanobacteria- Recap of talk by Dr. Andrew Knoll & Dr. David Grinspoon

The Talk:

“Planetary Changes from Deep Time to the 4th Kind”

The Speaker:

Andrew Knoll of Harvard and David Grinspoon of the Planetary Science Institute

The Sponsor:

Planet and Life Series, sponsored by MIT Earth, Atmospheric, and Planetary Sciences dept. (EAPS)

These are the questions being addressed by The Planets and Life Series at MIT, and the kick-off event, held back in September (unfortunately, I do not get paid to write this blog) was a doozy.
