What risks matter most for the long term future of civilisation. When does a disaster become existential. This lesson outlines and distinguishes these key concepts.

- Unrecoverable Dystopia: Humanity survives but in a permanently damaged or oppressive state.

3.3.2 Global Catastrophic Risk and Existential Risk

Learning:
- Read Ord, pages 39 to 43.
- Review Lesson 2.9 Managing Existential and Global Catastrophic Risks .
Reflection: Focus on the difference between these two types of risk:
