Many politicians, the public, and some scientists still think that economic development is a major cause of reduced birth rates in developing countries. We tested this belief empirically in a recently published long-term study of many countries (1970-2014). We found no relationships between fertility and economic growth, but a strong association with modern contraception: birth rates…
At the end of 2022, the Wittgenstein Centre for Demography and Human Capital held a conference titled Population and Climate Change: The Defining Relationship of the 21st Century.

In a new article, he argues that humanity is deep into ecological overshoot and that we need to ratchet back our numbers and the size of our economies before nature does it for us. by Philip Cafaro William Rees has…
Are many tiny ecological footprints more virtuous than fewer, larger ones? Will they be better for the Earth, or easier to accomplish? These hard questions need to be asked as humanity hurtles past 8 billion people and deeper into ecological overshoot. By Gaia Baracetti You’ve all heard the argument: high birth rates in poor countries…
On 15 November 2022, Earth’s human population will pass 8 Billion, according to estimates by the United Nations.

Allen I have found myself checking out the population counter on my website more and more often as it approaches…
