Heather Roy interviews Simon Ewing-Jarvie about what he thinks the country will look like in 2050 and beyond. This episode traverses Statistics NZ population projections as well as the views of well-known academics such as Professor Paul Spoonley and the late Professor Paul Callaghan. It also discusses likely implications of these and other demographic changes ranging from the Antarctic Treaty to energy generation and distribution, nuclear ship propulsion, schooling and a widening wealth gap in a 'three-nation New Zealand.'
