Maybe it was a viral pandemic, or an asteroid strike, or perhaps nuclear war. Whatever the cause, the world as we know it has ended and you and the other survivors must start again. What key knowledge would you need to start rebuilding civilisation from scratch? Once you've scavenged what you can, how do you begin producing the essentials?
