This talk by Gail Bradbrook of Extinction Rebellion (XR) may be the best and most comprehensive presentation on this topic to date. In my mind, it is a Keynote Address to the Human Species. Please take the time to watch it; there may be nothing more important. It is 50 minutes in length, and every minute is riveting in a quiet but powerful way. One would do well to view it repeatedly and take close notes. To her credit, she provides a minute of silence between parts I and II.
Part I: She discusses the ecological crisis: the latest science on what risks there are, and our current trajectory, including the possibility of abrupt (i.e. near term dramatic climate change) and human extinction.
Part II: She deals with understanding our emotional responses and what appropriate responses we might make.
I encourage you to view this presentation in its entirety, read the ABOUT page of this blog, and then take a long solitary walk.
