Staying within safe planetary boundaries for global resource use and pollution makes good sense. Are there a complementary set of economic and social measures that could help human societies remain within ecological limits? by Erik Assadourian Not long ago a new update to the Planetary Doughnut was published in Nature, complete with 35 indicators to…
Should migrants be “blamed” for rising house prices? Or should we set aside blame and acknowledge that population growth, whatever the source, has some negative impacts? by Gaia Baracetti I recently had the good fortune of visiting Vancouver, a city where I used to live a long time ago. While still beautiful, it appeared to me…
All around the world, politicians, business leaders, academics and many members of the general public worship at the shrine of ‘growth’. They are profoundly and dangerously wrong. by Sandy Irvine, eco-activist from England To grow or not to grow is the really big issue of our times. Most problems boil down to excess growth –…
The Jus Semper Global Alliance is dedicated to building a better world based on democracy, sustainability and fairly sharing the world’s wealth. Its website gathers valuable material on a full range of issues regarding economic, social and ecological justice. As its founder and executive director reminds us here, “no matter how efficient and fair the…
While population growth lies at the root of many environmental problems, concerned citizens often feel disempowered from addressing it. A popular initiative in Switzerland may provide a blueprint for activists in other developed countries. by Roland Schmutz After Swiss voters narrowly rejected joining the European Economic Area in 1992, the European Union and Switzerland began…
William Rees explores the nature of humanity’s relationship with energy and the ecosphere, and reaches the unsettling conclusion that a population ‘correction’ is in the offing. By William Rees What would you think if someone called you out as a ‘dissipative structure’? Or better, claimed that you were a ‘thermodynamically far-from-equilibrium dissipative structure’? Chances are,…
These islands were more-or-less isolated, microcosms that perhaps tell us what is going to happen with the global population. Anthropological accounts also describe remarkable forms of birth control. Do they tell us anything about how to achieve sustainable populations today? By Frank Götmark Easter Island, and historical background One of the most debated questions…
The ancient Greeks have exerted tremendous influence on western thought and culture, including in the realm of ethics. Yet few today realize that the founders of western political philosophy advocated a steady-state economy and limits to human numbers. by Theodore P. Lianos In the fifth century B.C., the Athenian philosopher Socrates (470-399) changed the course…
The concept of optimum population size is nothing new, but in recent decades the methodology used to calculate it has seen little development. In a recently published book, We Zijn Met Te Veel (Dutch for We Are Too Many), a new approach is proposed for calculating optimum population size. by Fons Jena In the available literature…
A recent book introduces a new approach to the science of overpopulation. We Zijn Met Te Veel (Dutch for We Are Too Many) explores a new theoretical foundation for the concept of overpopulation and explains why a smaller human population is a necessary – but not sufficient – condition for a more hospitable world. by…
Too many people consuming too many resources and generating too much waste: that’s why humanity keeps pushing deeper into ecological overshoot. On Earth Overshoot Day, let’s not forget the P factor. by Lucia Tamburino & Philip Cafaro Every year on Earth Overshoot Day, a table like the one below makes the rounds, showing the number…
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…
Many readers of our blog probably see no problem with “overpopulation,” but we sometimes get negative responses when we use the word, even from colleagues who largely share our views. Why is this so? How should overpopulation best be defined? By Frank Götmark, Jane O’Sullivan and Phil Cafaro In contrast to other organisations dealing with…
Greenwashing typically means conveying a false impression or providing misleading information about the environmental soundness of a company’s products. But governments, too, can be tempted to greenwash, as this week’s blog illustrates. Gary Wockner describes how the city council of Boulder, Colorado has declared a climate emergency, while hiding the increased emissions caused by growth through “creative”…
By Jane O’Sullivan, Francesco Ricciardi, Susann Roth For sustainable development, universal wellbeing should be the goal, rather than endless growth. Minimizing further growth in human populations is only part of the solution, but an essential part. Climate change has been described as one of the greatest challenges of our time. But for many Asian countries,…
Too often, it seems, matters of population are overlooked in discussions of global sustainability. And this is true, despite some rather obvious points: A world of, say, 5 billion people is more likely to be sustainable than one of 10 billion; and a world of 1 billion is likely more sustainable still. All things being…
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…
Mahatma Gandhi said: “Earth provides enough to satisfy every man’s need but not every man’s greed.” What is then the “right” lifestyle, which we all should adopt to be sustainable? It depends on how many people there are on the Earth. Sustainability does not depend only on lifestyle, but also on how many people share…
In a new review article published in the journal Environment, Development and Sustainability, Elias Ganivet reminds us that we need to address both excessive human consumption and population growth, to curb humanity’s environmental impact. Written from a very balanced perspective, Ganivet reviews the impacts of human population growth on global biodiversity and climate change, perceptions…
A new international billboard campaign encourages the public and policymakers to “Celebrate Low Birthrates!” and “Shrink Towards Abundance!” The goals of the campaign are to draw attention to the benefits of declining populations and encourage politicians to rethink and reorganize the current economic system to take advantage of depopulation dividends. The environmental benefits of declining…
