Professor Ken Smail has put together the best argument for facing depopulation.
Its full title was Acknowledging and Confronting the Inevitable: A Significant Shrinkage in Global Human Numbers, and Other Inconvenient Truths. Some readers may find Ken's timing-scenario for depopulation optimistic -- picturing it further off into the future than the 21st century -- but he acknowledges its possibly being played out earlier due to today's "toxic brew" of crises.
Assuming then, my postulata as granted, I say that the power of population is indefinitely greater than the power in the earth to produce subsistence for man.
- Thomas Malthus (1798)
It has become increasingly apparent over the past half-century that there is a growing tension between two seemingly irreconcilable trends. On one hand, moderate to conservative demographic projections indicate that global human numbers will almost certainly reach 8 to 9 billion by mid-21st century, only two generations from the present. On the other, prudent and increasingly reliable scientific estimates suggest that the Earth's long-term sustainable human carrying capacity, at what might be defined as an “adequate” to “moderately comfortable” developed-world standard of living, may not be much greater than 2 to 3 billion. It may in fact be considerably less, perhaps in the 1 to 2 billion range, particularly if the normative life-style (level of consumption) aspired to is anywhere close to that currently characterizing the United States.
As a consequence of this modern-day “Malthusian dilemma,” it seems reasonable to suggest that it is now time -- indeed, past time -- to think boldly about the midrange future, and to consider alternatives that go beyond merely slowing the growth, or even the stabilization, of global human numbers. In this brief essay, I shall argue that it has now become necessary for the human species to develop and implement, as quickly as possible, a well conceived, clearly articulated, flexibly designed, broadly equitable, and internationally coordinated program focused on bringing about a very significant reduction in global human numbers over the next two or more centuries. In simple quantitative terms, this effort will likely require a global population “shrinkage” of at least two-thirds to three-fourths, from a probable mid-to-late 21st century “peak” in the 9 to 10 billion range to a future (23rd century and beyond) “population optimum” of not more than 2 to 3 billion, or perhaps even fewer.
