The paper … Continue reading The moral imperative of depopulation

Something you don’t know about Qatar and something you know about China (but it’s wrong)

Despite obvious differences, Qatar and China have something in common: disinformation, myths and lack of information surround these two countries. Looking at data instead of anecdotes discloses surprising facts and enables a better understanding of these countries’ demographic policies. It also sheds light on how population policies can drive unbalanced sex-ratios. by Lucia Tamburino and … Continue reading Something you don’t know about Qatar and something you know about China (but it’s wrong)

Population growth has contributed 80% of ecological overshoot

William Rees is the originator of ecological footprint analysis, the influential approach to measuring sustainability. In a new article, he argues that humanity is deep into ecological overshoot and that we need to ratchet back our numbers and the size of our economies before nature does it for us. by Philip Cafaro William Rees has … Continue reading Population growth has contributed 80% of ecological overshoot

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 … Continue reading The per capita fallacy

Population and Cheap Labour

Herman Daly has made more fundamental contributions to specifying a truly sustainable economics than any economist of the past half century.

The United Nations celebrates World Population Day by shaming population ‘alarmists’

Not content with omitting overpopulation concerns from its own rhetoric, in its World Population Day statement the UNFPA has gone on the attack, labelling all concerns about the numbers of humans ‘alarmist’.

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 … Continue reading Two ways to argue for population’s importance

Breaking boundaries but not population taboos

The book Breaking Boundaries by Johan Rockström and Owen Gaffney explains the basics of how the Earth works and how humanity is rocking the boat, ecologically speaking.

The “Silent Lie” in Coverage of Madagascar’s Famine

Graphic media coverage of the current hunger in southern Madagascar is not wasting the opportunity to advocate climate justice. But nobody mentions there are now seven Madagascan mouths to feed for each one present in 1950.

Reconciling human demands with planetary boundaries: a new approach to quantifying sustainability at the national and global levels

Human population grows, Earth doesn’t. A certain environmental impact is needed to satisfy basic human needs. When multiplied by a huge population, even a small average individual impact can become high, overshooting planetary boundaries. Achieving both environmental sustainability and high human development is hence a challenge. Can we win this challenge without considering the population … Continue reading Reconciling human demands with planetary boundaries: a new approach to quantifying sustainability at the national and global levels

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 … Continue reading The most ethical gift: Towards a sustainable demographic future

Why we must become fewer people and consume less – and suggestions to improve the situation

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 … Continue reading Students view human population growth as a threat to biodiversity

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 … Continue reading The moral case for population reduction

Population Dynamics, the Concept of a “System,” and the Law of Unintended Consequences

An eminent economist weighs in

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.
