The last 100 years have seen a boom in trade, prosperity and wealth across the world, at unprecedented rates in human history. As a species, we are now more wealthy, healthy, and less likely to be killed in conflict than ever before, despite the many horrors we see in the daily news cycle.

This golden age we live in has run in tandem with an ever-expanding population; in the 1920s, there were only two billion people on the planet. A century later, that number has skyrocketed up to eight billion. Yet the increase of prosperity and people has come at a devastating price – global warming, the melting of the ice caps, an epidemic of plastic pollution and the mass destruction of the planet’s biodiversity are all intrinsically connected to population growth. More recently, however, the trend has been bucking. The watchful eyes of demographers have been drawn to data that reveal a world of ageing societies, plummeting birth rates, and dwindling populations. Surely this must be a good thing for the planet and therefore humanity … right? Armed with a file full of “population bomb” headlines – the explosion will happen mid-century, when humans will peak around 8.5 – 9 billion people, followed by drastic falls – we embark on a worldwide exploration with a very unique purpose. What truths and human stories can we discover behind the red flag statistics? What are the population tipping points of fertility, birth and death rates? And how, among the other culprits of climate change, conflict, global health and over consumption, might they make or break the future of our life on earth?
