The virtual closure of Australia’s borders in response to the covid-19 pandemic has seen overseas immigration completely stopped. Some see this as a further blow to the economy while others see it is an opportunity to reset Australia’s growth-oriented population policy. This talk will examine Australia’s population dynamics and consider the consequences of both low and high population growth. This issue will also be considered in a global context, with the possibility of global food shortages and massive refugee flows. But is there really a global population bomb, as Paul Ehrlich famously predicted back in 1968, or should we not be concerned?
