Dodging Extinction - Discussion w/ Cal Prof Anthony Barnosky

Dodging Extinction: Power, Food, Money & the Future of Life on Earth
Presentation & Discussion with Cal Professor, Anthony Barnosky
During the past 500+ million years in which complex life has existed on Earth, there have been five massive extinction events when three quarters or more of all species on Earth have been extinguished. Cal professor, Anthony Barnosky, shows us in his new book how global warming and other environmental impacts caused by human beings are bringing on a Sixth Extinction. Unless unprecedented measures are taken to change the trajectory we are on – most species could be wiped out within a few human generations. Join us for a discussion of both the science behind this environmental emergency and the extraordinary changes required immediately to avoid one of the greatest disasters in the history of life on earth.
