******************************

Inferno is a great thriller, featuring Tom Hanks reprising his role as Professor Robert Langdon. The previous movie adaptations of Dan Brown’s books (Angels and Demons and The Da Vinci Code) were a success, and I expect Inferno will do well in theaters, too.

Langdon is a professor of symbology whose puzzle solving skills and knowledge of history come in high demand when a billionaire leaves a trail of clues based on Dante’s Inferno to a biological weapon that would halve the world’s population.

The villain, however, has good motives. As a radical Malthusian, he believes that the human race needs halving if it is to survive at all, even if through a plague. Malthus’s name is not mentioned in the movie, but his ideas are certainly there. Inferno provides us an opportunity to unpack this overpopulation fear, and see where it stands today.

Thomas Malthus (1766–1834) thought that the potential exponential growth of population was a problem. If population increases faster than the means of subsistence, then, “The superior power of population cannot be checked without producing misery or vice.”

Is overpopulation a problem?

The economics of population size tell a different, less scary, story. While it is certainly possible that some areas can become too crowded for some people’s preferences, as long as people are free to buy and sell land for a mutually agreeable price, overcrowding will fix itself.

As an introvert who enjoys nature and peace and quiet, I am certainly less willing to rent an apartment in the middle of a busy, crowded city. The prices I’m willing to pay for country living versus city living reflect my preferences. And, to the extent that others share my preferences or even have the opposite preferences, the use and construction of homes and apartments will be economized in both locations. Our demands and the profitability of the varied real estate offerings keep local populations in check.

But what about on a global scale? The Inferno villain was concerned with world population. He stressed the urgency of the situation, but I don’t see any reason to worry.

Google tells me that we could fit the entire world population in Texas and everybody would have a small, 100 square meter plot to themselves. Indeed, there are vast stretches of land across the globe with little to no human inhabitants. Malthus and his ideological followers must have a biased perspective, only looking at the crowded streets of a big city.

If it’s not land that’s a problem, what about the “means of subsistence”? Are we at risk of running out of food, medicine, or other resources because of our growing population?

No. A larger population not only means more mouths to feed, but also more heads, hands, and feet to do the producing. Also, as populations increase, so does the variety of skills available to make production even more efficient.  More people means everybody can specialize in a more specific and more productive comparative advantage and participate in a division of labor. Perhaps this question will drive the point home: Would you rather be stranded on an island with two other people or 20 other people?

Malthus wouldn’t be a Malthusian if he could see this data

The empirical evidence is compelling, too. In the graph below, we can see the sort of world Malthus saw: one in which most people were barely surviving, especially compared to our current situation. Our 21st century world tells a different story. Extreme poverty is on the decline even while world population is increasing.

He sees that as populations and economies grow, more have access to birth control and limit the size of their families. In this video, he shows that all countries are heading toward longer lifespans and greater standards of living.

Finally, there’s the hockey stick of human prosperity. Estimates of GDP per capita on a global, millennial scale reveal a recent dramatic turn.

The inflection point coincides with the industrial revolution. Embracing the productivity of steam-powered capital goods and other technologies sparked a revolution in human well-being across the globe. Since then, new sources of energy have been harnessed and computers entered the scene. Now, computers across the world are connected through the internet and have been made small enough to fit in our pockets. Goods, services, and ideas zip across the globe, while human productivity increases beyond what anybody could have imagined just 50 years ago.

I don’t think Malthus himself would be a Malthusian if he could see the world today.

Overpopulation: Pictures vs. Numbers – Article by Bradley Doucet

Overpopulation: Pictures vs. Numbers – Article by Bradley Doucet

******************************

Two hundred years ago, there were about a billion humans in the world. Today, there are seven billion and counting. This fact has some people concerned that we’re going to run out of food, energy, or other important resources in the foreseeable future. Some worry that we’re going to pollute the natural environment so much that we render it uninhabitable, or at least much less habitable.

As an example of such concerns, a friend of mine recently posted a link to a series of photographs purporting to show that the planet is overpopulated. The first shows “Sprawling Mexico City roll[ing] across the landscape, displacing every scrap of natural habitat.” Another shows greenhouses “as far as the eye can see” in Spain. Another still, a surfer threading the eye of a wave that is littered with garbage.

Some of the photos in this series are actually quite beautiful, but some are indeed ugly, and all are arresting. Yet as evocative as these images are, the scenes they depict are just tiny snippets of an enormous planet. Mexico City, sprawling though it is, covers an area of about 1,500 square kilometres. That may sound like a lot, but it’s just 1/100,000 of the Earth’s 150 million square kilometres of land area. The things illustrated by these photos may be bad—although some are frankly neutral—but they tell us nothing about how widespread the specific problems they allude to may be. To determine the scope of the population issue, pictures are not sufficient; we need the help of numbers.

How Many Is Too Many?

“We undeniably face huge challenges,” admits Hans Rosling in the opening minutes of Don’t Panic: The Truth about Population, “but the good news is that the future may not be quite as gloomy and that mankind already is doing better than many of you think.” In this hour-long documentary, Rosling, a Swedish professor of global health and a renowned TED-talk speaker, makes the numbers behind population growth come alive. And while not denying that human activity does indeed often cause pollution as a side effect, and does indeed use resources, he challenges the narrative of the doomsayers.

Most importantly, he drives home the fact that population growth is already slowing. Yes, Bangladesh’s population has grown dramatically in his lifetime, he tells us, tripling from about 50 million to about 150 million. But do we need to convince Bangladeshis to have fewer children? No, because the job is already done. Although still a poor country, Bangladeshis have grown richer in recent decades. As many of them have moved out of extreme poverty, child mortality rates have plummeted, and birth rates have fallen in turn. Bangladeshi women now have just over two children each on average.

There are still places in the world with much higher birthrates, of course, primarily in rural parts of Asia and Africa. But contrary to public perception, much work has already been accomplished. And as more of the poorest nations move out of poverty in the coming decades—Africa and Asia being home to the fastest growing economies in the world—birthrates will come down everywhere. The best estimates are that we will hit about 9 billion by mid-century, and top out at around 10 or 11 billion by 2100. After that, no more population growth.

But 11 billion is still a lot. Can the Earth sustain even that stable population?

We should of course try to limit our negative impact on the environment as much as we can, within reason. But that is precisely what we have been doing as we have gotten richer and have been able to afford to care more about the state of the natural environment. And contrary to what doomsayers like Paul Ehrlich predicted in the 1960s and 1970s, there has not been mass starvation in the industrialized world, and there has been less and less of it in the poorer parts of the planet. If you think the future nonetheless still looks grim, you may not be looking hard enough, because there are in fact many reasons to be optimistic.

Are there now, or will there soon be, too many of us? Part of your answer to that question depends on whether you think of each new human being as just another mouth that needs feeding, or whether you recognize that those mouths generally come attached to human minds—the ultimate resource.

******************************

That overpopulation exists at all is one of the most prevalent delusions in the modern world: thanks to the environmentalist movement, a cause that has ascended near to the status of civic religion, the average fellow in the street thinks that there are too many people alive today, that resources are stretched to breaking point, that the future is one of Malthusian decline, and that horrible poverty in the third world is caused by the existence of too many people. All of these points are flat-out wrong. Humanity is wealthier and has greater access to resources today than at any time in history, the variety and amounts of available resources are growing at an accelerating pace due to technological progress, the earth could support many times more people than are alive today, and where there is poverty it exists due to terrible, predatory governance and the inhumanity of man – it exists due to waste and aggression amidst the potential for plenty.

Even this pro-longevity piece by George Dvorsky subscribes, as many do, to the false idea that somehow we are consuming too many resources and will run out. This is silly: resources are infinite, because through technological progress we constantly develop new ones. People live in an age of change, with each new decade clearly different from the last, and yet live under the assumption that everything will remain the same going forward. Being worried about running out of anything that we use today is like being worried about running out of candle wax in 1810, or running out of room for horse breeding operations in 1840, or running out of food in 1940. All false concerns, and all false for exactly the same reasons: we are not static consumers of resources, we are net producers of resources.

Quote:

Make no mistake, it’ll take us a long, long time to get there, but we’ll eventually find a way to halt the aging process. Owing to advanced medical, regenerative, and cybernetic technologies, future humans will enter into a state of “negligible senescence,” a condition marked by the cessation of aging and the onset of everlasting youth. It sounds utopian, but as biogerontologist Aubrey de Grey has repeatedly noted, it’s simply an engineering problem – one that’s not intractable.

I’ve been debating this issue for the better part of a decade, and I’ve heard virtually every argument there is to be said both in favor of and in condemnation of the possibility. I’m not going to go over all of them here. But without a doubt the single most prominent argument set against radical life extension is the issue of overpopulation and environmental sustainability.

As a final note, there’s a certain inevitability to radical life extension. It’s the logical conclusion to the medical sciences. So rather than futilely argue against it, we should come up with constructive solutions to ensure that it unfolds in the most non-disruptive way possible.
