In the second part of our Population Policy Case study series, following Indonesia, The Overpopulation Project Team examines the history of population policies in the Islamic Republic of Iran. Iran stands out for lowering its fertility in a very short time without coercion. The total fertility rate dropped from almost 6 in 1988 at the … Continue reading The Iranian miracle: The most effective family planning program in history?
By Massimo Livi Bacci Four population-driven threats to space If from abstract principles and paradigms of my previous article (Malthus, forever?), we turn to the real, contemporary world, we may say that the rapidly expanding world population also has other consequences – beyond the reduction of “pristine” space – that may adversely affect the quality … Continue reading Four compelling reasons to fear population growth
Indonesia: Population Policy Case Study 1 By Jenna Dodson Population policies of the late 20th century played a central role in the global decline in fertility rates1. These policies mobilized resources to enact policies aimed at reducing fertility by widening contraception provision and changing family-size norms. In the first of a series of Positive Population … Continue reading “Two Children Are Enough” – “Dua Anak Cukup”
By The Overpopulation Project Here at The Overpopulation Project, we try to keep a positive outlook. Although many environmental trends are grim, there exist clear paths forward toward a more sustainable world: one where people steward resources for the future and share habitat and resources generously with other species. Recently, a correspondent wrote challenging us … Continue reading Solutions to overpopulation and what you can do
By Patrícia Dérer The primary cause of the global biodiversity crisis is human-induced alteration and loss of natural habitats1. One of the most important causes of habitat destruction is housing growth, manifested both in rural and urban sprawl. The impacts of housing growth derive from both building human dwellings and their associated infrastructure such as … Continue reading Housing growth threatens biodiversity – are we ignoring fundamental causes?
By Stephen Williams Without a fundamental change to economic thinking, Australia will continue down the dystopian road, argues Stephen Williams. [The Prime Minister of Australia], Scott Morrison, met with state and territory leaders in Adelaide recently for the COAG chinwag. Topping the list of agenda items was population. I will try and summarise the population problem as succinctly … Continue reading New Australian population plan will be meaningless
Population growth is a potential political and social issue. And just like any issue, it requires recognition from both the public and politicians to be added to the agenda. Although population growth may not be a topic that compels you to call your representative, surveys from the Global Challenges Foundation (GCF) show that perhaps it … Continue reading Public believes population growth negative, risky, and requiring international attention, while politicians look the other way
Changing social norms are important in changing fertility behavious such as using contraception that in fact effects our environment through population dynamics

By Jan van Weeren Last month, the United Nations Population Fund (UNFPA) presented its report The Power of Choice, declaring that every woman should have the right to decide freely and responsibly whether, when and how often to have children. This right complies with article 16 of the Universal Declaration of Human Rights (UDHR) stating … Continue reading Whose freedom of choice?
By Jane O’Sullivan Why would an organisation dedicated to protecting natural areas and to saving wild animals turn its back on arguably the biggest threat? WWF used to highlight human population growth, but not anymore. Populations of wild animals have declined, on average, by 60% since 1970. This alarming statistic was announced in WWF’s 2018 Living … Continue reading WWF Living Planet Report 2018 – “aiming higher”, but not on target
By Patricia Dérer In the following exercise, we demonstrate how different migration and fertility-influencing policies can lead to large differences in future annual greenhouse gas emissions, and in cumulative emissions throughout the century in the European Union. We present nine scenarios representing migration and fertility policies leading to stable, declining, or growing populations. The scenarios … Continue reading Population growth will make it harder to meet EU climate goals, while stable or declining populations will help cut greenhouse gas emissions in the EU
TOP believes there is no better video presentation on the consequences of overpopulation than Sir David Attenborough’s RSA (Royal Society for the encouragement of Arts, Manufactures and Commerce) President's Lecture. The well-known British naturalist delivers an impressive speech explaining why population growth is a multiplier of every environmental problem. Given that the Earth has physical limits, “sustainable … Continue reading People and Planet – Sir David Attenborough’s take on overpopulation

By Richard Grossman Family planning was declared to be a basic human right fifty years ago. The right to family planning was included in the International Conference on Human Rights held in Tehran, May 1968. The concept of universal human rights started after World War II with the United Nations. Its charter included the obligation … Continue reading Recognize family planning as a human right
Our blog about Factfulness led to comments, discussion and finally a response from one of its authors (note: the book is written in Hans Rosling’s voice and is the joint work of Hans Rosling, Ola Rosling, and Anna Rosling Rönnblad; Hans Rosling died in February, 2017). Ola Rosling states that he welcomes our criticism and … Continue reading Can the book “Factfulness” be improved?
by Jenna Dodson How much of the planet should we leave for other forms of life? How much of the planet can the 7.6 billion present-day human inhabitants utilize without sacrificing the well-being of future generations? These are important questions with far reaching implications for all species, Homo sapiens included. People are placing unprecedented demands … Continue reading Space for Nature
By Patrícia Dérer Thirty countries around the world have declining human populations. With the exception of Japan, these are European countries that, along with the rest of Europe, have successfully undergone the “demographic transition”. Impressive achievements in health care, education and economic development have resulted in lower child mortality and longer life expectancy, leading to … Continue reading Rethinking depopulation and land abandonment – the opportunity of rewilding
by Philip Cafaro Most political liberals and most academics across the developed world support expansive immigration policies, often up to and including free movement and settlement across national boundaries (“open borders”). They may agree to limit immigration for tactical reasons, because their benighted fellow citizens are not willing to be more generous. But they remain … Continue reading Immigration ethics for a world of limits
by Frank Götmark This year Hans Rosling, Ola Rosling, and Anna Rosling Rönnblad (below the “Rosling team”) published “Factfulness” (Note: H.R. died in February 2017.) As the book to a large extent is about global population and as Bill Gates is giving free copies of it to college graduates in the US, we need to … Continue reading ”Factfulness”: a more accurate title for this new book would have been ”Selecting Facts to Make You Happy”
Interview in Metro with Frank Götmark, 21.08.2018, translated from Swedish. See the original article here (pages 14-15)! The climate threat is now on everyone's lips. However, it is rarely mentioned together with population growth, despite the fact that they interrelated. That is why actions to dampen population increase are missing, though they would lead to powerful … Continue reading Population growth is a threat to the world’s climate
By Patrícia Dérer Many of us still remember how researchers, environmentalists and the media were concerned about population growth between the 1950s and the 1980s. Many of us could also notice, that this concern and attention declined during more recent decades, despite continued population growth. Nowadays there is almost a complete silence about overpopulation, both … Continue reading Evidence for the changing discourse on population growth in an environmental magazine
By Dr Peter Matanle Japan is experiencing unprecedented demographic change, due to rapid ageing and, since 2008, decreasing population. Conventionally this is considered to be a ‘problem’ to be solved by increasing either fertility or immigration, or both. Neither of these is realistic, however. More children would increase age-related dependency ratios, and the number of … Continue reading Japan’s depopulation dividend: searching for an alternative to growth at all costs
For the original Opinion article published in one of Sweden’s largest morning newspaper (Svenska Dagbladet), and for 47 mainly positive comments (in Swedish) click here! In the discussion about the environment and our future, overpopulation should also be highlighted. The issue is often avoided in the debate - even though it is central. We urge … Continue reading UN’s Agenda 2030: add the goal “Slow down population growth”
By Trevor Hedberg, University of South Florida The global human population is currently about 7.6 billion people, and our numbers are still increasing. Although human population growth has not been a popular topic to discuss in the last quarter-century, its contribution to various environmental problems is becoming harder and harder to ignore. Travis Rieder’s Toward a Small Family … Continue reading Toward a small family ethic: How overpopulation and climate change are affecting the morality of procreation
By Patrícia Dérer Sri Lanka and the Indian Western Ghats (also known as Sahyadri Mountain Range) make up one of 36 Biodiversity Hotspots. These areas are the Earth’s most biologically rich—yet threatened—terrestrial regions; they were designated in order to preserve the most species. The Western Ghats belong to the eight “hottest hotspots” based on their … Continue reading High human population density eliminates the positive effect of forest protection in a tropical biodiversity hotspot

By Alisha Graves There's no single solution for climate change, no magic bullet that can stabilize and eventually reduce the concentration of greenhouse gases in the atmosphere. But separating sex from childbearing represents an underappreciated opportunity to forestall climate disaster. To be sure, addressing the climate challenge will require a wide range of approaches. Conservation … Continue reading Green sex for climate’s sake
By Jenna Dodson The United States’ birth rate has fallen to a 30-year low, and the media is giving this new figure much attention. Unfortunately, most of that attention is misplaced. Since last week, countless news organizations released articles reviewing the new report from the Centers for Disease Control and Prevention (CDC) that documents the 3,853,472 … Continue reading US birth rate lowest in 30 years – the overlooked benefits
by Rob Harding Recently, an international assembly of scientists from 184 countries endorsed an article published in the journal Bioscience entitled “World Scientists’ Warning to Humanity: A Second Notice”. As the warning states, “We are jeopardizing our future by not reining in our intense but geographically and demographically uneven material consumption and by not perceiving continued rapid population … Continue reading A proposal for a United Nations Framework Convention on Population Growth
By Frank Götmark In "Responsible Use of Language in Scientific Writing and Science Communication"1 Kueffer and Larson discussed the role of language and concepts in scientific writing and communication. Researchers increasingly depend on marketing strategies to publish their findings and to obtain funding, according to the authors. They were especially interested in strong metaphors that may … Continue reading Are scientists using proper words to describe the negative influence of humans on the Earth’s ecosystems?
by Phil Cafaro Given current consumption levels and the ongoing attempt to increase them as fast as possible (through increased economic growth, the chief goal of most national governments) a strong case can be made that Earth is overpopulated. It almost certainly cannot support the current human population of seven and a half billion people … Continue reading One Child: Do we have a right to more?
by Patrícia Dérer It is possible to estimate an optimal human population size based on various criteria and assumptions. Here, we do not deal with the lower bound of the human population (the minimum viable population) as we are certainly well above that limit. Concerning the upper bound, we have to consider the carrying capacity … Continue reading What is the optimal, sustainable population size of Humans?
