History was rewritten to delegitimize population concerns: we need to reassert the truth

In the old fable of the Emperor’s New Clothes, people denied the emperor’s nakedness because they wanted to be seen as smart. Today people deny overpopulation because they want to be seen as moral. It is a form of virtue signaling: are you for justice and equity and families and being nice to refugees, or … Continue reading History was rewritten to delegitimize population concerns: we need to reassert the truth

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

The demographic fantasies of the IPCC

Climate change is now unequivocally an emergency according to the latest report from the IPCC. Our only hope lies in extremely rapid abandonment of fossil fuels and reversal of forest loss. But these lifeline scenarios also assume birth rates plummet in high-fertility regions. Jane O’Sullivan offers a reality check. By Jane O'Sullivan The Intergovernmental Panel … Continue reading The demographic fantasies of the IPCC

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

There were 250 … Continue reading 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

IPCC and IPBES Ignore Overpopulation Again

In a new report, a joint workshop convened by the Intergovernmental Panel on Climate Change and the Intergovernmental Panel on Biodiversity and Ecosystem Services warned that the climate and biodiversity crises need to be tackled in tandem.

Demographers fail to acknowledge the effect of population growth on climate change

A recently published article asked European demographers about their attitudes towards climate change and population growth.

Australia’s Population Ponzi Scheme

The current economic system in Australia is a Ponzi scheme based on maintaining positive GDP through migration. Populations of native species are plummeting and people are faced with increased job insecurity and housing costs, all of which are side effects of the Australian government's ongoing drive for an ever increasing population. by Kelvin Thomson In … Continue reading Australia’s Population Ponzi Scheme

A Decreasing Population Furthers Rewilding Efforts in Romania’s and Ukraine’s Danube Delta

Since the fall of the Eastern bloc, both Ukraine and Romania have seen their populations shrink. Driven by rural to urban migration, low fertility rates, and substantial emigration, the depopulation in the Danube Delta region has opened up large areas to rewilding efforts.

Climate refugees or overpopulation escapees?

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 … Continue reading Climate refugees or overpopulation escapees?

Societies can avoid a world population of 10.8 billion and related disasters – with education, contraception and emphasis on sustainability. by Joe Bish Human civilization faces a severe long-range mismatch between sustainable food yields and global population size.

Fewer People = More Wild Nature in Croatia’s Velebit Mountains

In the Croatian alps, declining human populations have gone hand in hand with expansions of protected lands and resurgent wildlife populations. Large predators are finding their way back to the region now that the anthropogenic pressures have lightened, and rewilding efforts have ensured the comeback of both mountain-dwelling herbivores and large grazers on the adjacent … Continue reading Fewer People = More Wild Nature in Croatia’s Velebit Mountains

Restoring Abandoned Land in the Oder Delta Gives New Opportunities for Wildlife in Germany and Poland

From Population to Production: Scientists’ Changing Views on How to Feed the World

Fifty years ago, in his 1970 Nobel Peace Prize acceptance speech, Norman Borlaug said: “There can be no permanent progress in the battle against hunger until the agencies that fight for increased food production and those that fight for population control unite in a common effort.” Borlaug was insightful, but also a genuinely humble man. … Continue reading From Population to Production: Scientists’ Changing Views on How to Feed the World

Fewer people leads the way to rewilding in Portugal

Depopulation has led to abandonment of less fertile agricultural lands throughout Europe. Portugal, with its declining population, is a prime example. In the Côa Valley, the abandonment of farmland has been turned into an opportunity for rewilding efforts to create new wilderness. Already the valley has seen the return of many endangered species, such as … Continue reading Fewer people leads the way to rewilding in Portugal
