So the following is theatre, and (a bit!) theatrical.
The audience is second year students at University of Manchester. Their lecturer wanted a lively and staged (in every sense) debate between someone arguing that Malthus was wrong/there are no limits on human ingenuity/technological progress will make everything better and better forever and… well, the “we’re doooooooomed” school of thought. Oddly she came to me to provide the latter. I hope I obliged?
