Almost everyone acknowledges that the world’s population is growing dangerously fast. Almost no one seems to be doing anything about it. This piece is an attempt to understand why.

The numbers are worth sitting with for a moment.

For 200,000 years, the human population stayed below one billion. It crossed two billion in 1927, three billion by 1960, and stands roughly at eight billion today — with no signs of stopping.

By 2050, the world population is projected to cross 10 billion, surpassing what scientists estimate the Earth can sustainably support. A University of Washington professor of statistics and sociology, Adrian Raftery, states that “there’s a 70 percent probability the world population will not stabilise this century.”

Most of this growth — over 80 percent — is projected to occur in Africa and Asia, the world’s poorest regions, compounding existing inequality. As a result, the number of people living in poverty could increase substantially.

The world’s population has quadrupled in less than a century, yet concern about population growth largely remains on the backburner. Why?

Experts point out that the problem is not numbers alone. The consumption patterns of wealthy populations — disproportionate use of resources, carbon output, waste — compound the damage. By 2050, oceans could contain more plastic than fish by weight.

In November 2017, more than 15,000 scientists from 184 countries signed a joint statement calling rapid population growth the ‘primary driver’ of ecological and societal collapse. It was largely ignored.

Despite decades of data, the global policy conversation has largely shifted away from population as a problem. If anything, the dominant narrative now frames population growth as economically necessary — more consumers, more workers, more taxpayers. The ecological cost of that framing is rarely counted.

A 2009 report by the United Nations Food and Agriculture Organisation (FAO) estimated that the world will have to produce 70 percent more food by 2050 to feed a projected extra 2.3 billion people. The extra food and shelter for the additional population will require encroaching upon agricultural land and natural resources for construction and housing. Where the employment and livelihoods for billions of additional people will come from is a question that demographic projections rarely answer.

Feeding 10 billion people will require either a radical transformation of agriculture or an expansion of factory farming practices that scientists already identify as conditions that increase the risk of zoonotic disease outbreaks. Covid-19 offered a preview of what scientists have long warned: that the conditions created by human overcrowding and industrial agriculture are ideal for generating and spreading novel pathogens.

Also in 2009, the UK government’s chief scientific adviser, Prof John Beddington, warned that growing populations, falling energy reserves and food shortages would create a “perfect storm” of shortages of food, water and energy by 2030.

Yet if the dangers are so widely acknowledged, an obvious question arises: why has population growth largely disappeared from political debate?

WHO PROFITS FROM A CROWDED PLANET

Consider where the world’s largest revenues accumulate.

Health and life insurance depends on a large, ageing population paying premiums. Real estate thrives on population density driving up land value. Oil, gas and automobile industries need billions of consumers. Pension funds require expanding workforces to remain solvent.

Each of these industries — pulling in the highest-revenue on Earth — has a structural interest in population growth continuing: pharmaceutical revenues scale with population; fossil fuel consumption rises with it; arms sales grow with the number of unstable, populous states. Most of these companies are owned by international conglomerates.

The Stockholm International Peace Research Institute (SIPRI) estimated $400 billion in arms sales in 2017. The world’s largest arms buyer, Saudi Arabia, imports far beyond what its military can absorb — a pattern that reflects procurement as geopolitical signalling rather than defensive necessity.

These industries and corporations exert significant influence over governments through lobbying and political engagement for their commercial interests and motives. Their common foundation is the size of the ‘market’ — the bigger the better. They are the direct beneficiaries of the world population bursting at the seams.

That is why, whether it is the United Nations, the World Economic Forum or any other international organisation, economic growth remains a central priority. For institutions whose primary mandate is economic growth, a stable or shrinking population is not a solution — it is a threat. The ecological cost of expansion is an externality they are not designed to count.

THE LOBBY AGAINST THE FUTURE

As commentator Tyler Cowen has noted, the great technological leaps of the 20th century — nuclear power, computing, the internet — were driven not by markets but by governments mobilised for war. The implication is uncomfortable: the threats that get solved are the ones that serve powerful interests.

Population pressure — scarcity, unemployment, resource competition — has historically been among the preconditions for the instability that makes arms sales necessary and wars possible. The military-industrial complex does not cause overpopulation, but it has little reason to prevent it.

When governments decide a threat is real and urgent, the pace of response is extraordinary — the rapid development of Covid-19 vaccines or the eradication of smallpox. Overpopulation has never been granted that status. The question is why.

A PROBLEM WITH NO CORPORATE SOLUTION

The reason overpopulation goes unaddressed, in the end, is not ignorance. The data has existed for decades. It is that the industries which shape global policy — insurance, real estate, pharmaceuticals, arms, fossil fuels — are the direct beneficiaries of a crowded planet.

More people means more customers, more patients, more soldiers, more consumers. The world’s population problem has no corporate solution — which is why, so far, it has had no solution at all.

That leaves governments, civil society and citizens — the only actors whose interests are not served by the status quo. Whether they can be mobilised before the projections become reality is the only question that matters.
