Professor Nick Bostrom of the University of Oxford talks to Global Policy's Dr. Jill Stuart about the possibility of existential threat and how academics and practitioners can begin to think about how to tackle these risks.

'Existential risk is something that has never happened in all of human history. It is defined as something that either causes the extinction of earth ridden or intelligent life or that permanently and drastically will destroy our future potential for desirable development.' - Professor Bostrom
