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

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

People and Planet – Sir David Attenborough’s take on overpopulation

Immigration ethics for a world of limits

by Philip Cafaro Most political liberals and most academics across the developed world support expansive immigration policies, often up to and including free movement and settlement across national boundaries (“open borders”). They may agree to limit immigration for tactical reasons, because their benighted fellow citizens are not willing to be more generous. But they remain … Continue reading Immigration ethics for a world of limits

Population growth is a threat to the world’s climate

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.

Evidence for the changing discourse on population growth in an environmental magazine

By Patrícia Dérer Many of us still remember how researchers, environmentalists and the media were concerned about population growth between the 1950s and the 1980s. Many of us could also notice, that this concern and attention declined during more recent decades, despite continued population growth. Nowadays there is almost a complete silence about overpopulation, both … Continue reading Evidence for the changing discourse on population growth in an environmental magazine

Japan’s depopulation dividend: searching for an alternative to growth at all costs

By Dr Peter Matanle Japan is experiencing unprecedented demographic change, due to rapid ageing and, since 2008, decreasing population. Conventionally this is considered to be a ‘problem’ to be solved by increasing either fertility or immigration, or both. Neither of these is realistic, however. More children would increase age-related dependency ratios, and the number of … Continue reading Japan’s depopulation dividend: searching for an alternative to growth at all costs

Are scientists using proper words to describe the negative influence of humans on the Earth’s ecosystems?

By Frank Götmark In "Responsible Use of Language in Scientific Writing and Science Communication"1  Kueffer and Larson discussed the role of language and concepts in scientific writing and communication.

One Child: Do we have a right to more?

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.
