The Myth of Overpopulation
There are now eight billion individuals residing on the planet. Is there enough room for everybody? Are we going to lack food and other resources? Marian Tupy, Senior Fellow at the Cato Institute and co-author of Superabundance, examines whether or not these worries are valid. His response may surprise you.

There are now eight billion people surviving on the world.
Is there enough space for everyone? Aren’t we going to run out of natural deposits? How are we going to feed everybody?
These are not new questions. Doomsayers have been asking them for at least 200 years.
In 1798, an English economist called Thomas Malthus, wrote his famous Essay on the Principle of Population. In it, Malthus claimed that population grew exponentially, while resources needed to feed that population grew at a direct rate.
The distinction in between the 2 growth rates, he argued, must result in hunger.
Malthus was incorrect. And not by a little; by a lot. As the population grew, food production enhanced … therefore did almost everything else.
Think about the life of a typical American blue-collar worker over the period of a century. Using an unit of measurement known as time costs, we can estimate the amount of time somebody would have to work to buy a given item.
In between 1900 and 2018, the length of time our blue-collar worker needed to work to make sufficient money to buy a pound of pork fell by 98%, to buy a pound of rice by 97%, to purchase a pound of coffee, 94%.
While individuals can’t eat rubber, aluminum, or cotton, these commodities are important inputs in the production procedures that impact the rates of items and services, and thus the general standard of living. Their prices fell by 99%, 98% and 96% respectively– while the population of the United States rose from 76 million to 328 million.
Scarcities, which were when common, have actually disappeared beyond war zones. In much of the world today, it’s weight problems not hunger, that’s a problem.
This relationship in between population development and abundance may seem counterproductive, but it’s real.
Remember this chart that so scared Malthus? The truth looks really various.
The more individuals we have, the more abundance we have. Relative to previous generations, we now live in a world of superabundance– the term that my colleague and co-author, Gale Pooley and I have actually coined and use as the title of our book.
What makes this superabundance possible?
The response is understanding.
Thomas Sowell, the fantastic Hoover Institution economic expert, discusses it this way:
The difference in the standard of living in between the cavemen and us is not natural resources. And we utilize that understanding to make things from the same natural resources that existed during the time of the cavemen, however which the caveman might never have envisioned.
Let’s look at something as easy as a grain of sand. It has been lying around for billions of years. Some 4,500 years earlier, somebody figured out that by heating sand to simply over 3,000 degrees Fahrenheit, sand might be turned into glass beads, then glass containers, and much later, windowpanes.
With every step of discovery, the worth produced from a grain of sand increased. Today, we use glass in fiber optic cables and computer microchips, turbocharging our productivity, therefore making us much more thriving than our forefathers.
Counting the quantity of recognized basic materials, like Malthus and lots of other people have actually done, might seem logical, but it misses the active ingredient that changes everything: understanding.
And brand-new knowledge emerges from the human mind. A newborn comes into the world not just with an empty stomach, but likewise a brain capable of intelligent, possibly world-changing thought.
What truly matters is not the finite number of atoms on the planet, be they of copper or zinc or any other element, however the human ability to integrate and recombine those atoms in ever more important ways.
We can with confidence say that economic development is less about resources, which are limited, and more about knowledge, which is limitless.
As the Nobel Prize-winning economic expert Paul Romer put it, originalities “do not add up. They multiply.”
