Most people now live in countries where two or fewer children are born for every two adults.
This is a troubling article by UT Austin economist Dan Spears on predictions that world population growth will peak sometime during the 2060s to 2080s, and then will rapidly decline. We all know on some level that human population growth cannot continue at this pace, but the sudden drop that experts predict in the near future is alarming--as are the predicted consequences of a rapid human population decline.

The global human population has been climbing for the past two centuries. But what is normal for all of us alive today—growing up while the world is growing rapidly—may be a blip in human history. Children born today will very likely live to see the end of global population growth.A baby born this year will be 60 in the 2080s, when demographers at the U.N. expect the size of humanity to peak. The Wittgenstein Center for Demography and Global Human Capital in Vienna places the peak in the 2070s. The Institute for Health Metrics and Evaluation at the University of Washington puts it in the 2060s. All of the predictions agree on one thing: We peak soon.
And then we shrink. Humanity will not reach a plateau and then stabilize. It will begin an unprecedented decline. Because most demographers look ahead only to 2100, there is no consensus on exactly how quickly populations will fall after that. Over the past 100 years, the global population quadrupled, from two billion to eight billion. As long as life continues as it has — with people choosing smaller family sizes, as is now common in most of the world — then in the 22nd or 23rd century, our decline could be just as steep as our rise.
The article goes on to say:
[...] What would happen as a consequence [of a rapid decline in human population]? Over the past 200 years, humanity’s population growth has gone hand in hand with profound advances in living standards and health: longer lives, healthier children, better education, shorter workweeks and many more improvements. Our period of progress began recently, bringing the discovery of antibiotics, the invention of electric lightbulbs, video calls with Grandma and the possibility of eradicating Guinea worm disease. In this short period, humanity has been large and growing. Economists who study growth and progress don’t think this is a coincidence. Innovations and discoveries are made by people. In a world with fewer people in it, the loss of so much human potential may threaten humanity’s continued path toward better lives.
I encourage you to read the rest of this article. Whether or not one agrees with Dr. Spears's arguments, they are thought provoking.
