Population growth depends strongly on fertility rates, so it is important to study factors that determine fertility. Despite much research, there is no consensus about the most important factors involved, except that contraceptive use can be effective. Factors correlated with declining as well as increasing or high fertility should be studied simultaneously. Religiosity is potentially … Continue reading Fertility levels in global regions and countries: what is the role of religion?
Planet earth’s future cannot be bright with 8 billion people: our future depends on how seriously and quickly we change our materialist culture, social organization and technologies. An immediate action plan is offered for the generation centered around Greta Thunberg: young women, and just as importantly young men, should avow not to have children until their … Continue reading A potential pledge: no change, no grandchildren
Empty Planet: The Shock of Global Population Decline claims that (a) life on earth is stressed but coping with the present level of human impact; (b) global population will peak in 2050; (c) subsequent population decline will alleviate ecological problems; and (d) countries with populations that are only slowly growing should act now to boost … Continue reading Part 2 Review of “Empty Planet: The Shock of Global Population Decline”

In the 1960s and 70s, South Korea experienced one of the fastest fertility declines in the world, halving the number of children born per woman from over 6 to less than 3 in just 18 years. In large part, this was due to early government recognition that fertility reduction is a component of development, a … Continue reading Low fertility in South Korea: a springboard for social change and conservation
By John McKeown Empty Planet moves confidently from an optimistic premise to unwarranted conclusions. It has been reviewed favourably by Steven Pinker, The Wall Street Journal and the New Statesman, among others. Its premise is that world population will peak far lower and sooner than the UN forecasts, and that because of a faster-than-expected decline in … Continue reading Review of “Empty Planet: The Shock of Global Population Decline” Part 1

These projections differ from … Continue reading New policy-based population projections for the European Union, with a consideration of the environmental implications
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 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

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
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 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 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?
