A brief history of Planet Earth, humans, and civilisation. Population growth, the Malthusian trap, and the power of exponential change.

A short history of Doomsters and Boomsters featuring Dr Strangelove, twenty billion chickens, and Playboy magazine. At the heart of this story is a wager over the future of our planet. A bet between a celebrity biologist and a subversive economist with diametrically opposed visions of the future.
