Political demographer Jennifer D. Sciubba discusses the implications of global population decline, including low fertility rates and population aging. She emphasizes the need for planning and adaptation to a smaller population, while debunking the idea that higher birth rates are the solution. The podcast explores the consequences of failing to adapt, such as limited reproductive choices and decreased global cooperation. It also offers ideas on embracing population aging, including immigration, longer working years, and technology. Investing in health and sustainable consumption is important, as well as recognizing the untapped resource of older populations for a resilient and beautiful world.
