Scientists Propose Shrinking Earth's Population to 4 Billion by 2200 (2 Photos)

A team of researchers argues this move is essential to conserve vital resources. However, they are not calling for direct population control; instead, they believe the reduction will happen naturally if girls in the world's poorest nations are given access to education.





A multi-institutional team of scientists published a study in the journal Sustainable Development making the case for a gradual decrease in the global population. Specifically, they propose bringing the human population down from today's 8.3 billion to 4 billion by the year 2200.

According to the paper, the world's population has doubled over the past 50 years. During the same period, carbon dioxide emissions have more than doubled, biodiversity has dropped by half, energy consumption has tripled, and both mining activity and pesticide use have quadrupled. If current trends persist, the global population could reach 11.4 to 12.4 billion by 2100, which would lead to catastrophic consequences for ecosystems and natural resources.

The researchers contend that a smaller population would curb resource consumption, lower pollution, ease competition for water, land, and food, and give nature a chance to recover.



The authors emphasize that they are not advocating for coercive measures like China's former "one-child policy." Instead, they are confident that a "soft" population reduction can be achieved simply through voluntary family planning, by expanding women's access to education and reproductive healthcare services in poorer countries. As examples, they point to Iran, where fertility rates plummeted from 4.08 to 1.94 births per woman in just nine years, and South Korea, where the rate dropped from 4.07 to 1.92 over twelve years.

“Reducing the population to a sustainable level will not deprive billions of people of life; rather, it will ensure thriving conditions for future generations when they are born,” the study's authors write.
