“Overpopulation threatens the world’s food supply, United Nations warns”

That was the front-page headline in the New York Times last Thursday, August 8th, announcing a new report from the IPCC, “Climate Change and Land.” I’m kidding, of course.

How should environmentalists think about immigration?

Between toxic calls for immigration controls based on racial criteria and hyperbolic denunciations of any mention of population issues as “ecofascist,” the room for intelligent and honest discussion of immigration policy is being gobbled up from both the Left and the Right.

Low fertility in South Korea: a springboard for social change and conservation

In the 1960s and 70s, South Korea experienced one of the fastest fertility declines in the world, halving the number of children born per woman from over 6 to less than 3 in just 18 years.

When the heroes win, everybody loses

Human overpopulation is real; it’s serious and needs to be humanely handled by conscientious and charitable individuals. Thanos from the Avengers movies is neither one of those things. He recognized the problem but acted viciously on his “solution,” phasing out of existence 50% of all intelligent life in the Universe. What Thanos ended up doing … Continue reading When the heroes win, everybody loses

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

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
