Wildlife in decline: the impact of human population growth and consumption
In a short film about wildlife loss, Nastaran Rahnama takes a broad approach, investigating food sold in the UK, its production far away, and the links to population growth and declining large mammals.

Adversity for Biodiversity: A Reflection on My Experience at COP15
The Kunming-Montreal Global Biodiversity Framework1 adopted in December 2022 by representatives of most of the world’s national governments is inadequate to halt and reverse the disturbing loss of biodiversity globally. Concerted efforts to increase the new Framework’s ambition were dismissed and ultimately ignored. Human overshoot – the collective impacts of more than eight billion people…

Dangerous distraction or elephant in the room? The role of population growth during three decades of increasing carbon emissions
How often have you heard some version of this claim: “population growth is not a problem for climate change, because populations are growing in poor countries whose contributions to global emissions are negligible”? It gets repeated like a mantra, soothing words that banish thought. But what justifies a claim is not the number of times…

Smaller human populations are neither a necessary nor sufficient condition for biodiversity conservation
That’s the title of a paper just published in Biological Conservation in response to TOP’s recent paper on population and biodiversity loss in that journal. Are its authors right? by The Overpopulation Project In one sense, Alice Hughes and company clearly are correct. Efforts to protect wild nature are ongoing throughout the world, and for…

Boiling Frogs
Human population growth has exploded during the last century, decimating wildlife and devastating ecosystems. Without honest conversations about overpopulation, continued growth will likely condemn most wild animals to extinction and leave us with a much poorer planet By Brad Meiklejohn “Fewer people, more wild animals. Right now that feels like coming back from a time…

The Great Multiplier
At the end of 2022, the Wittgenstein Centre for Demography and Human Capital held a conference titled Population and Climate Change: The Defining Relationship of the 21st Century.

Eight Billion – Our Greatest Mistake
According to the United Nations Population Fund, reaching a global human population of 8 billion is an achievement to be celebrated. In “a world of infinite possibilities,” they state, “imagine the boundless paths 8 billion can take.” Rather than taking refuge in irresponsible fantasies, it’s time our bloated societies reckoned honesty with demographic reality. By…

The per capita fallacy
Are many tiny ecological footprints more virtuous than fewer, larger ones? Will they be better for the Earth, or easier to accomplish? These hard questions need to be asked as humanity hurtles past 8 billion people and deeper into ecological overshoot. By Gaia Baracetti You’ve all heard the argument: high birth rates in poor countries…

Two ways to argue for population’s importance
Here at TOP, we are often asked how we define overpopulation and whether it’s a helpful concept. Good questions! Below I propose a definition of overpopulation, after first considering the suggestion that it’s not necessary or helpful to deploy the term, even —or especially! — if we want to convince our societies to accept good…

What have you learned in school about population? Please tell us!
Many of our readers may have memories from their school years of lessons about population growth – or perhaps memorable situations when population talk was avoided. As far as we know, there are few studies regarding how population is taught around the world. TOP wants to know more about this, whether your memories are from…

Population in the IPCC’s new mitigation report
A new IPCC climate change mitigation report confirms that population increase and economic growth are the main drivers of today’s historically high greenhouse gas emissions. But that scientific information has been censored and removed from the Summary for Policymakers distributed to the world’s press and the public. Does a problem disappear if we don’t mention…

The most ethical gift: Towards a sustainable demographic future
Demographic changes are not immediate, but rather take a long time to happen. In an article originally posted in The Ecological Citizen, Joe Bish argues that the population discussion needs to be reframed as an imperative to achieving a long-term sustainable civilisation, rather than an overriding priority for near term goals. By Joe Bish The…

Students view human population growth as a threat to biodiversity
In their curriculum, university students in biology and environmental sciences rarely learn how human population growth affects the environment, or discuss its role relative to other factors. Human activities are often dealt with in courses, but not population increase. One exception, described below, comes from a Swedish ecology class that learned about and discussed how…

The moral case for population reduction
A frequent assumption in population policy debates is that stabilizing populations will be sufficient to achieve ecological sustainability. But as Karin Kuhlemann observes, “that a population’s size is stable in no way entails sustainability. It may be sustainable, or it may be far too large.” A recent book from philosopher Trevor Hedberg convincingly argues the…

Demographers fail to acknowledge the effect of population growth on climate change
A recently published article asked European demographers about their attitudes towards climate change and population growth. It shows that while most demographers are in agreement on the need to act on climate change, the effect of population growth is largely not understood. By The Overpopulation Project An article published in March this year in the…

Humanity needs to halt both population growth and climate change
Many of today’s environmental problems are more due to population growth than climate change, and climate change is driven in part by continued global population growth. Development funding to make family planning and modern contraceptives universally available could make a big difference in solving these interlocking problems. By Malte Andersson, Frank Götmark, and Anders Wijkman…

Boiling Frogs
by N.R. Baker According to the well-known metaphor, if you were to put a live frog into boiling water, it would – very wisely – leap straight out again. However, if you put the frog into tepid water that was then brought slowly to the boil, the hapless creature would be cooked before it even…

Climate refugees or overpopulation escapees?
In recent years, migrants fleeing overpopulation and lack of economic opportunity have been rebranded as “climate refugees” by corporate media looking to justify open borders. But expanding migration will simply fuel continued population growth, leading to greater resource consumption, higher greenhouse gas emissions and worse climate change. It’s a Ponzi scheme perpetuated by falsehoods that’s…

Will global population peak below 10 billion?
A major media storm has erupted about a new scientific paper published in the Lancet claiming that global population will soon peak and decline. The prospect is met with doom and gloom, rather than jubilation. But Jane O’Sullivan finds many reasons to challenge both the claim and its assumed economic threat. By escalating unfounded fears…
