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. Some experts suggest a population sized at approximately two people per arable hectare would be ecologically sustainable. … Continue reading Addressing Population Challenge Is Not Impossible
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?

Since last week, countless news organizations released articles reviewing the new report from the Centers for Disease Control and Prevention (CDC) that documents the 3,853,472 … Continue reading US birth rate lowest in 30 years – the overlooked benefits
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. It almost certainly cannot support the current human population of seven and a half billion people … Continue reading One Child: Do we have a right to more?
by Patrícia Dérer It is possible to estimate an optimal human population size based on various criteria and assumptions. Here, we do not deal with the lower bound of the human population (the minimum viable population) as we are certainly well above that limit. Concerning the upper bound, we have to consider the carrying capacity … Continue reading What is the optimal, sustainable population size of Humans?
By Jenna Dodson Sustainable development has been defined as development that meets the needs of the present without compromising the ability of future generations to meet their own needs1. Using this definition, the United Nations developed a sustainable development framework centered around three pillars: economic, environmental, and social. Population is included in the social pillar … Continue reading Including population growth in sustainability discussions, case study: Egypt

Recently, in “The impact of population growth and climate change on food security in Africa: looking ahead to 2050”, Hall et al. reaffirmed population growth to be … Continue reading Population and food security in Africa: a win-win opportunity
