As ecosystems deteriorate and wealth inequality deepens, the impact of overpopulation on the natural world is well-documented—but its effects on democracy, social cohesion, and psychological well-being remain largely unexplored. This essay examines how our bloated, hyper-complex societies have outgrown their ability to meet individual needs, leading to a breakdown in political and social structures.
By Michael Bayliss
With 8.2 billion people navigating an increasingly fragmented world, collective narratives have spiralled out of control, fuelled by social media echo chambers and misinformation. The cognitive limits of human connection, as explored by thinkers like Yuval Noah Harari and Jared Diamond, suggest that civilizations struggle to function beyond a certain scale. The modern world has temporarily bridged this gap through technology and propaganda, yet this has only accelerated economic disparity, political disillusionment, and environmental destruction.
As economic instability mounts and the middle class erodes, societies risk turning to simplistic, authoritarian solutions—historically a precursor to fascism and oligarchy. However, the answer lies not in reactionary politics but in systemic change: planned degrowth to scale back unsustainable economies, rewilding to restore ecological balance, and family planning to address overpopulation in a humane and equitable way.
Ultimately, escaping our current dystopian trajectory requires dismantling our self-absorbed narratives and re-establishing a connection with the natural world. The more of us there are, the harder this becomes—making population sustainability not just an environmental necessity, but a psychological and human rights imperative.
Not just an ecological disaster
The impacts of human overpopulation on the natural world have been widely studied and intensely debated. We are witnessing its effects firsthand as ecosystems collapse around us. Less examined, however, is how population pressure influences social values such as democracy, equity, and social organisation. Rarer still is the exploration of its psychological and spiritual consequences at both individual and community levels.
In my article for Population Media Center, “Population Growth and Wealth Inequality Are More Entwined Than We Thought: Here’s Why,” I discussed how rapid population growth exacerbates inequality, increases overconsumption, and dilutes both democracy and innovation. These areas warrant further study and discussion.
The recent decline in political and social cohesion underscores my concern that our globalized society has grown too vast and complex to adequately meet the diverse and individual needs of 8.2 billion people.
When societies become too big to handle
Research suggests there are cognitive limits to the number of social relationships the human brain can sustain. In Sapiens, Yuval Noah Harari argues that beyond our cognitive capacity for 150 stable relationships (what is referred to as Dunbar’s number), societies must rely on abstract symbols such as branding, myths, and bureaucracies to maintain cohesion. Similarly, in Collapse, Jared Diamond suggests that civilizations throughout history have ultimately crumbled under the weight of their own size and complexity, unable to adapt to disruption. The difference between the case scenarios detailed by Diamond and our current predicament is that as our societies have become global and interdependent, there is no ‘release valve’ of somewhere else to run off to in times of crisis.
While modern technology has temporarily allowed us to function within an increasingly vast and globalised system, it has done so through tools of rapid communication, transactions, and most notably, advertising and propaganda. This has turned most of us into participants within a homogenous, ever-expanding system that accelerates its own growth while consuming the living world at an ever-faster pace.
While GDP growth continues to increase in the Global North, if we look at GDP per capita, it is arguable that average living standards have arguably peaked, stagnated or even declined. Yet the invisible forces driving our growth-based economy have convinced us that this system is both inevitable and natural, with deregulated, trickle-down economics framed as an unquestionable law of progress.
Unlike the kings and emperors of old, today’s ruling classes have until recently, hidden behind the illusion of democracy. Politicians, increasingly funded by billionaires, serve as their public enablers and apologists, while election cycles across many nations force voters to choose between two parties offering increasingly indistinguishable policies. Yet the real power remains out of reach, untouched by the ballot box. As their dominance grows more absolute, billionaires have become increasingly brazen—just ask Elon Musk.
This intricate, self-perpetuating system has, until now, been flexible enough to bind together 8 billion people. But several fault lines are beginning to crack. The cost-of-living crisis is one example driven by the natural limits to growth, a speculative economy built on inflated property prices rather than real productivity, and worsening wealth inequality. The result is a hollowing out of society, eroding the middle and working classes. History suggests that such conditions often precede the decline of once-mighty empires.
Living in a crowded world of 8 billion relative truths (and counting)
During the COVID years, while we were disrupted from our normal routines of ‘work and consumption’, there was some hope that we would emerge from the lockdowns recalibrated and with a better set of priorities. Unfortunately, on reflection, it appears a very different reality has played out. While mainstream society appears to have doubled down on the mantra of ‘growth is good’, a wave of conspiracy theories have proliferated, creating more division than ever. Disinformation can spread like wildfire, even as the planet burns.
Human societies have always existed within relative truths. Money, economics, hierarchy, even morality, are constructs of our collective subjectivity, shaped through language. While a necessary tool for navigating complexity, language can become dangerous when our egos become entangled in the ephemeral world of narratives. Today, as communities corrode—due in part to austerity and in part to sheer overpopulation – we find ourselves increasingly fragmented, living in close quarters yet seemingly unable to organise cohesively. As our worlds become more insular, myopic, and self-absorbed, our narratives spin further out of control.
As always, nature knows best
In my experience, the biosphere and the natural world exist (generally speaking) beyond the realm of human storytelling. It is the closest thing we have to an objective reality, a physical truth unshaped by human interpretation. For most of our history, the natural world vastly outweighed the human world. Even as civilizations rose and fell, nature provided a grounding force, a check and balance against our self-created illusions. But today, that balance has been obliterated. Wild mammals now account for just 4% of global mammalian biomass. For many, access to the natural world has been reduced to curated, artificial experiences, such as a trip to the city zoo or a national park, often more about aesthetics and Instagram posts than genuine reconnection.
The ratio of human-made to natural environments has inverted so dramatically that we are now almost entirely subsumed by our own creations. Physically, we are enclosed by sprawling suburbs, towering apartments, and endless urban landscapes. Virtually, we are consumed by screens and social media; an echo chamber of human narratives. With little access to nature, is it any wonder we have entered a post-truth era, where so many feel lost?
Unmoored and ungrounded
The psychological scale of this crisis is staggering. How can a globalised society truly address 8.2 billion individual narratives, each with unique needs and grievances? The only common thread seems to be that no one feels fully heard or understood, not even billionaires, who often appear more insecure and unhappy than the rest of us. The more people there are, the more each individual voice is drowned in an ocean of noise. This weight, though intangible, is deeply felt.
No one can sustain this burden alone. In confusion and desperation, many seek simple solutions to complex, unfathomable problems. This is when the temptation arises to rally behind the loudest, angriest figure in the room; the one who projects unshakable confidence and offers the illusion of easy answers. History has shown us where this path leads: fascism, oligarchy, tyranny, scapegoating, and, inevitably, dystopia.
No magic bullet solution
Complex problems require complex, multi-layered solutions. There is no single fix, only a collective effort. Our bloated, unsustainable societies must embrace planned degrowth, scaling down economies to levels that do not literally cost the Earth. We must rewild—restoring balance between the human and natural world, reviving biodiversity, and making space for life beyond ourselves. We must finally confront the population issue with maturity and seriousness. This is not a matter for conspiracy theories or reactionary outrage, it is a fundamental issue of human rights, environmental stability, and long-term well-being. Expanding global access to family planning not only slows population growth but also empowers women, strengthens communities, and fosters economic resilience. In the Global North, choosing to have fewer children has a greater impact on carbon emissions than multiple lifestyle changes combined. A stable or declining population should be seen as a success, not a crisis, regardless of what Elon Musk might claim.
Ultimately, the only way to escape this dystopian spiral is to let go of our self-absorbed narratives and re-establish our relationship with the natural world. To do so means actively working to look for connection and common ground among those we disagree with as a pathway towards constructive discourse. For this reason, new activist movements such as Holistic Activism and older ones such as Deep Ecology are becoming increasingly important. However, the more of us there are, the harder this becomes both physically and psychologically. Population sustainability is not just an environmental necessity; it is a human rights imperative and I believe, a psychological one as well.
