Women carry the burden of contraception – is this sexism or just physiology?

Most contraceptive methods are aimed at women, an issue which Jackie Brown examines in a recent article in The Oxford Student. Brown discusses the great difference between the options available for women and men, and the inequality which arises from this. In response, retired gynaecologist Richard Grossman delves further into the complexity of side effects … Continue reading Women carry the burden of contraception – is this sexism or just physiology?

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

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?

Will global population peak below 10 billion?

A major media storm has erupted about a new scientific paper published in the Lancet claiming that global population will soon peak and decline. The prospect is met with doom and gloom, rather than jubilation. But Jane O’Sullivan finds many reasons to challenge both the claim and its assumed economic threat. By escalating unfounded fears … Continue reading Will global population peak below 10 billion?

New EU Biodiversity Strategy Fails to Address a Key Component of the Biodiversity Crisis – Human Numbers

The latest biodiversity strategy from the EU Commission makes some good suggestions for increasing protection for Europe’s dwindling biodiversity. While new, ambitious targets for protected areas and ecological restoration are welcome, the document fails to point out the central role population size will play in whether they are achieved. Through allowing the EU’s human population … Continue reading New EU Biodiversity Strategy Fails to Address a Key Component of the Biodiversity Crisis – Human Numbers

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

Autonomy and Overpopulation – Can They Co-exist?

The ongoing environmental crisis has prompted philosophers to examine the ethics behind limiting procreation in an overpopulated world. A paper published recently by Greg Bognar of Stockholm University aims to demonstrate that anti-natalist policy stances need not violate procreative liberty and personal autonomy. By Ayaka Paul In his new paper, “Overpopulation and Procreative Liberty,” Professor … Continue reading Autonomy and Overpopulation – Can They Co-exist?

Drawdown: a review of the Review

Can Human Use Be Combined with Biodiversity Protection in the Tropics?

With the ongoing tropical biodiversity crisis, protected areas play an important role for many species. But strict protection can harm local human communities that are reliant on the lands around them for survival. In addition, resources are often lacking to prevent illegal exploitation or hunting in strictly protected areas. Community-managed reserves have been suggested as … Continue reading Can Human Use Be Combined with Biodiversity Protection in the Tropics?

A lesson from the COVID-19 pandemic on the perils of density

In recent years, some environmentalists have argued that increasing population density is the key to creating sustainable societies. COVID-19 suggests they are mistaken. When increasing density becomes a substitute for setting limits to human numbers and demands on nature, environmental conditions deteriorate. And as usual, poor people and other species wind up paying the price. … Continue reading A lesson from the COVID-19 pandemic on the perils of density

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

With decreasing populations in parts of rural Europe and marginal agricultural lands being abandoned, Europe is in a strong position to return land to wilderness.

Fertility levels in global regions and countries: what is the role of religion?

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?

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

The Catholic Church and contraception

With continued global population growth, contraception and conscious planning for children remain critical moral issues facing today's families, no matter where they are living. Different religions have different views on birth control, and their official teachings influence millions of people’s fertility decisions. Below we take a closer look at the evolution of the Catholic viewpoint … Continue reading The Catholic Church and contraception

Is overpopulation a dirty word?

How should overpopulation best be defined? By Frank Götmark, Jane O’Sullivan and Phil Cafaro In contrast to other organisations dealing with … Continue reading Is overpopulation a dirty word?

Greenwashing growth: Boulder’s climate problem

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” … Continue reading Greenwashing growth: Boulder’s climate problem

TOP publishes new paper on the potential environmental impacts of EU immigration policy

Last year, TOP researchers published new policy-based population projections for the European Union. In a new companion piece, we explore the impacts of alternative immigration policies on two important EU environmental goals: reduction of greenhouse gas emissions and improved biodiversity conservation. We find that in both cases, less immigration, leading to smaller populations, will make … Continue reading TOP publishes new paper on the potential environmental impacts of EU immigration policy

Five myths about population, aging and environmental sustainability

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, … Continue reading Five myths about population, aging and environmental sustainability

The population question: Toward a plan for global sustainability

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 … Continue reading The population question: Toward a plan for global sustainability
