In contemplating the future of humanity, one cannot ignore the demographic trend that has gained traction across the globe: the dramatic decline in fertility rates. Once a world concerned with overpopulation, we now face a new reality where the slowing birth rate may pose one of the greatest challenges to societal stability, economic growth, and even the very survival of our species. As we ponder the implications of these changes, we arrive at a sobering question — could a controlled “culling” of the species, or a radical rethinking of what it means to thrive as humans, be necessary to ensure our survival?
While this proposition may sound dystopian or even unsettling, the framing of “culling” need not imply draconian measures, but rather a deliberate and ethical approach to managing the balance between human population and the planetary resources that sustain us. As fertility rates plummet and many countries face the specter of aging populations, we are confronted with an unprecedented opportunity to reshape our societies, values, and visions for the future of futures.
Understanding the Decline: Fertility Rates in Freefall
Globally, the total fertility rate (TFR) has seen a sharp decline over the past few decades. From an average of 4.97 children per woman in the 1950s, the global TFR has dropped to just below 2.4 in 2021, with many countries in Europe, East Asia, and North America falling below the replacement level of 2.1 children per woman. In countries like Japan, South Korea, and Italy, the TFR has dropped to around 1.3 or lower, while China’s once-booming population now faces similar issues after decades of the one-child policy.
Why is this happening? A confluence of factors is driving this shift: increased access to education for women, higher participation in the workforce, a shift in societal values prioritizing career and personal development, urbanization, and the soaring cost of living and childcare. As people are choosing to have fewer children or forgo parenthood altogether, birth rates are declining to levels that jeopardize the sustainability of current economic and social structures.
This demographic trend has far-reaching implications. Aging populations lead to shrinking workforces, increased healthcare and pension costs, and a heavier dependency burden on younger generations. The specter of population decline has raised alarms in several countries, sparking policy initiatives aimed at boosting fertility rates, such as subsidized childcare, parental leave benefits, and even financial incentives for having more children. Yet, many of these measures have had limited success, suggesting that a deeper, more existential shift is at play...
