"Unfortunately, the future will not be what we think it should be."
Ugo Bardi's The End of Population Growth: Reaching Humankind's Planetary Limits (a fresh Club of Rome report) delivers sobering news for anyone betting on endless demographic expansion. Global fertility is crashing faster than forecasts predicted, putting us at—or very near—peak human population, with outright decline possibly arriving in the coming decades, not mid-to-late century.
Drawing on systems dynamics, historical patterns, and updated data, Bardi calls this a millennia-long "U-turn" in growth, driven by resource constraints, environmental pressures, and socioeconomic factors. Societies, he warns, are woefully unprepared for the consequences: aging populations, shrinking labor forces, pension crises, and economic contraction.
For hardcore pro-natalists convinced we need dramatically more babies to avert civilizational stagnation or extinction, this book is kind of a buzz kill—it treats runaway population growth as a biophysical impossibility, not a policy puzzle solvable with tax credits or culture-war rhetoric.
Bardi isn't all doom and gloom, however; he highlights upsides to there being fewer humans on the planet—relieved pressure on ecosystems, potential climate benefits, and openings for smarter, sustainable policies—with real-world case studies to illustrate adaptation paths. Good luck getting current global leaders to adapt smartly and coordinate wisely!
