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

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 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.)

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!

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”.

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?
By Jenna Dodson Sustainable development has been defined as development that meets the needs of the present without compromising the ability of future generations to meet their own needs1.
