The CD titled “That Was the Year That Was” by Tom Lehrer was recorded in the year 1965. Lehrer expressed the need for the creation of songs pertaining to World War III in the introductory lines of his composition titled “So Long Mom (A Song for World War III),” suggesting that it would be prudent to commence their composition without delay. Another preoccupation of the 1960s, apart from nuclear annihilation, was overpopulation. The Population Bomb, by Stanford University biologist Paul Ehrlich, was released in 1968 during the highest worldwide population growth rate ever. Globalization has changed during the past 50 years. The shift in societal concerns from overpopulation to underpopulation has occurred as the apprehension of nuclear destruction has reduced. This blog entry aims to analyze the intriguing shift in population dynamics, considering several contributing factors.
The late 1960s witnessed a global surge in concerns around population increase. Human civilization appeared to be hurtling towards a point where finite resources would run out and living standards would decline. The current situation exhibits a stark difference.
Many demographic predictions predict that the global population will peak around the mid-20th century and thereafter fall slowly. Global population may fall by 2100. Mortality exceeds fertility in many nations, especially those with shaky economies. Several countries are approaching a critical threshold, beyond which their population sizes are projected to decrease by approximately 50%.
Lessons from Palaeontology
Upon examining historical documents, it becomes evident that Homo sapiens existed as a scarce species for a significant duration of its existence. The substantial reduction in genetic variety resulting from the fast expansion of populations poses a significant peril to the enduring viability of numerous species. Potential challenges may arise in the future as a result of the present circumstances.
Sperm Quality and Environmental Factors
The quality of human sperm has experienced a significant drop in recent decades, perhaps exerting an influence on fertility patterns and birth rates. Potential reasons that may contribute to this phenomenon encompass environmental influences and the psychological strain resulting from extended periods of closeness.
Economic Growth vs. Sustainability
Politicians often advocate for relentless economic growth, but this approach may not be sustainable in a world with finite resources. Human activities already sequester a significant portion of the Earth’s primary productivity, affecting not only other species but also potentially harming human economic prospects.
The Role of Women
The economic, reproductive, and political emancipation of women has doubled the workforce and improved various aspects of human life. With better contraception and healthcare, women are having fewer children later in life, contributing to declining birth rates.
The Silent Threat
One of the most insidious threats to humankind is “extinction debt.” This concept suggests that, even when a species appears to thrive, there comes a point where extinction becomes inevitable due to delayed reactions to habitat loss. Humans, dominant across the planet, may already be experiencing this phenomenon.
The Future of Human Population
When habitat degradation reduces available resources, fertility declines, birth rates fall below death rates, and genetic diversity becomes limited, a species is on a path toward decline.
As we examine these factors, it becomes increasingly plausible that the human population is not just headed for shrinkage but potentially collapse. The question that looms large is, “How fast?“
The international community now worries about underpopulation, not overpopulation, as in the 1960s. Environmental, economic, and social factors are shaping human civilization. Even with great precision, the future is hard to predict, but our species faces many risks that require reflection and prevention. Time will tell if humanity will die or adapt to their environment.
