In 1968, biologists Paul and Anne Ehrlich sounded the alarm with their groundbreaking book, The Population Bomb, highlighting the impending ecological crises tied to unchecked population growth. They warned that without significant measures to slow or reverse this growth, catastrophic consequences would follow.
Fast forward to today, and the global population has surged to over 8 billion—more than double its size since the Ehrlichs’ warning. As environmental threats persist, a new, unprecedented factor now influences the demographic landscape.
Notably, Italy has experienced a population decline of approximately one million since 2014, while Japan’s population has similarly decreased by about five million.
