In 1968, biologist Paul Ehrlich set off a global panic with the publication of The Population Bomb. The book opened with an ominous line: “The battle to feed all of humanity is over.” Ehrlich predicted mass starvation, ecological collapse, and resource depletion, all caused by a runaway human population. His message was stark—unless governments took immediate, drastic action to reduce birth rates, the world would face irreversible disaster.
Ehrlich’s work was widely embraced by institutions and policymakers. He became a media darling, and The Population Bomb was treated not just as a warning but as a blueprint for future planning. It influenced everything from academic discourse to international aid policies and family planning programs. But there was one major problem: almost none of Ehrlich’s predictions came true.
Instead of widespread famine, the world witnessed the Green Revolution, led by innovators like Norman Borlaug, who developed high-yield crop varieties that dramatically increased food production. Technological advancements in agriculture, medicine, and infrastructure outpaced population growth in much of the world. Humanity, far from collapsing under its own weight, adapted and innovated. The doomsday clock Ehrlich described never struck midnight.
Yet the damage was done. The myth of overpopulation had entered the cultural bloodstream.
When predictions go wrong - but policies remain
Despite being thoroughly debunked by real-world events, the fear-based overpopulation narrative refused to die. Instead, it morphed—no longer simply a concern about food shortages, but a justification for intrusive population control measures. One of the most devastating examples was China’s one-child policy, introduced in 1980 and lasting until 2015. The policy led to forced abortions, sterilizations, and the decimation of traditional family structures. It also created long-term demographic nightmares: an aging population, a gender imbalance, and a shrinking workforce.
All in the name of “saving the country.”
This should have served as a global wake-up call. But even today, the ghost of The Population Bomb lingers in discussions about climate change and sustainability. While climate change is a real and pressing issue, the idea that reducing the number of people as a primary solution is deeply flawed—and ethically perilous.
The new reality: Population decline, not explosion
Far from facing a population explosion, the world is now heading toward a profound population decline. Fertility rates have plummeted in country after country—below replacement levels in Europe, East Asia, and even parts of the Global South. Japan, South Korea, and Italy are all shrinking. Even China, once obsessed with limiting its growth, is now scrambling to encourage people to have more children.
This reversal has sparked new anxieties: Who will care for the elderly? Who will work to sustain economies? Yet these are not signs of failure—they are challenges that humanity, as it always has, can meet with innovation and resilience.
The problem with continuing to invoke overpopulation as a threat is that it blinds us to the real demographic transformations happening around us. Worse, it opens the door for authoritarian ideas about who gets to reproduce—and who doesn’t.
The persistence of a dangerous myth
Even in 2025, the myth of overpopulation persists. It finds new life in climate change debates, sometimes used to suggest that certain populations or regions should curtail reproduction for the good of the Earth. But population control is a slippery slope. When we tie a person’s right to have children to environmental outcomes, we risk reviving eugenic ideas under a green veneer. This is not just scientifically unsound—it is morally unacceptable.
The core problem isn’t that there are “too many people.” It’s how we organize ourselves, manage resources, and innovate for the future. Population is not a problem to be solved—it is the very fabric of human civilization.
Hope, humanity, and the future
History has shown that humans are not a burden—we are builders, problem-solvers, and creators. The failure of The Population Bomb lies not only in its poor predictions, but in its lack of faith in human ingenuity. From expanding food supplies to adapting to climate shifts, our track record is not perfect, but it is remarkable.
Rather than fearing the future or restricting people’s fundamental rights, we should invest in education, technology, and policies that support both freedom and sustainability. Whether populations grow or decline, the answer isn’t coercion—it’s cooperation and creativity.
The real bomb we defused wasn’t in the population—it was in the idea that people themselves are the problem. It’s time we buried that myth for good.
The idea that the planet can sustain infinite population growth is a the new pop science and a dangerous illusion.
While accurately extrapolating any trend into the future is difficult, given new variables that can disrupt trend lines.
And there is no question that the demographics of an aging population pose challenges—economic and otherwise.
But…Earth’s ecosystems have finite resources—clean water, arable land, biodiversity—all of which are under growing strain. While humans are indeed builders and problem-solvers, we are also consuming at rates that exceed the planet’s ability to regenerate.
In 2023, humanity used the equivalent of 1.7 Earths’ worth of resources—according to the Global Footprint Network—meaning we are depleting natural capital faster than it can be replenished.
We generate waste at such an alarming rate, some of it with a half-life of thousands of years—we are running out of places to store it. There are literal islands of garbage floating in our oceans.
The economic incentive to grow far outweighs the existential need to manage that growth in order to preserve earth’s fragile ecosystem. So no, it’s not alarmist to say we have a population problem. Although I’d say the issue is more complex than just a population problem. Humans are the most efficient predatory species on earth. We have a perspective problem.
