World population: Too many people or too few?

Summary

The world's population surpassed 8 billion in 2022, with India becoming the most populous country. However, a study suggests a potential decline to 6 billion by 2100. Many countries, including Italy, South Korea, and Finland, face demographic challenges due to aging populations and low birth rates. This decline raises concerns about labor shortages and economic sustainability. While some view population decline positively, citing reduced pressure on resources and increased societal development, others warn of the economic and labor force implications, including the potential for societal collapse in countries like Japan.
