Overpopulation – The Human Explosion Explained

If you're wondering how Iran did it in 10 years: Iran's birth control policy sent birthrate tumbling

In the late 1980s, Ayatollah Ruhollah Khomeini, Iran's supreme leader, issued fatwas making birth control widely available and acceptable to conservative Muslims.

Until then, Khomeini had helped foster a baby boom to produce soldiers for the war against Iraq. After the war, he was persuaded that the economy could no longer support a rapidly growing population.

Under the new decrees, contraceptives could be obtained free at government clinics, including thousands of new rural health centers. Health workers promoted contraception as a way to leave more time between births and help reduce maternal and child mortality. Couples intending to marry were required to receive counseling in family planning.

The birthrate plunged, helping to usher in social changes, particularly in the role of women.

As a young Bangladeshi, the change is so incredibly apparent in this nation.

I have 1 other sibling, my parents both had 7+ siblings.

It's strange how much birth rates can decline in just in one generation.

But why not mention Africa? (outside of barely mentioning South Africa) The African population is projected to reach 4 billion by the year 2100. Add to that the fact that global warming will strike the developing world the most and I just cannot see a future without mass migration.

Nobody seems to be playing devils advocate, so I'll throw in my two cents. As I see it, the real risk isn't that our population will continue to grow indefinitely (the video shows why this will very likely not be the case), rather it's that by the time our population finally does stabilize, humans will have already made much of the world uninhabitable through pollution, desertification, and ecological destruction. We are already in the midst of the largest mass extinction event since the asteroid that killed the dinosaurs. Increasing climate instability seems unavoidable (at least to some degree, it remains to be seen how much more damage we will do). Humans may well survive and reach a stable and eventually declining population, but the world will be a very different place, and will almost certainly be less hospitable.

SavantButDeadly · 7時間前

Okay, so developing countries will hit a stage where they are as advanced as us and their birth rates will decrease at that point. I can get that. Sure.

But the video said that the UN had estimated that balance to happen somewhere around 12 billion people on Earth? And what's the saying again? If everyone on Earth lived like an American, we would need 5 Earths? And that's for 7 billion. So we would need like 9 Earths for 12 billion american lifestyles then.

...I see no problem whatsoever with that.

Also, more people with access to stuff like antibiotics means that we will breed resistant bacteria faster than ever. Not to mention that we quickly need to produce more food to accomodate for all 12 billion, and much of Earths arable surface is already used up. There will be even more inhumane treatment and cramped conditions of livestock due to the increased demand. And so on and so forth.

The truth is that we're living in an experiment right now. We've never been in a situation like this, so everyone is taking guesses as to what will happen. But in my opinnion, unless we soon invent clean fusion power or a benevolent super AI that can rapidly advance our technology and capabilities, it's looking pretty bleak for both our species, other species and the planet in general.

I wonder if the direct causal relation between standards of living and fertility isn't putting things a bit too simply. This 4 step demographics model assumes uniform 'progress' across cultures and societies.

While current observations seem to fit the model nicely, there may be political, cultural, and social factors it doesn't account for. The prognosis may turn out to be accurate, it could be way off, too.

Take the one-child policy in China for example. Political decisions can have a great impact on demographics. Not to mention social norms.

Kinda bummed about this video. I was really hoping it would touch on the impact 7 billion people on the earth has, with our current technologies and limited timeframe of slowing down human induced climate change. I think my concern with overpopulation isn't, "will it just continue to grow over time?" My concern is, "how many people is too many people?" And I think we've well passed that threshold with the way most people in developed countries live.

So, eventually population will just kind of even out, apparently. What if (when?) we find some way around mortality? Surely then we're kinda screwed, population-wise?

anubis118 · 7時間前

Yeah population will level out, but what happens when the work hours available falls off a cliff over the next 50 years due to automation? What happens if there are enough jobs for 5 billion people, but 11 billion people live on the planet?

Charles Dickens wrote a line for Ebineezer Scrooge complaining about overpopulation in A Christmas Carol. People have been predicting doom from it for far longer than said doom was supposed to take to arrive.

bloodtearssilenthill · 6時間前

It's a nice video but it misses the point.

The concern isn't the population growth. The concern is the population stabilizing around 7 or 8 billion and that greater portion of that population consuming more.

As an example, imagine if I have a house and 4 people live in it. Then people keeping coming into my house throughout the week and now there are 700 people in my little house and then they stop coming. Well the population growth has stopped in my house, but there are still 700 extra people in it and those 700 people expect to be fed, clothed, have a car, have internet, etc. Those 700 demand the same quality of life that the original 4 inhabitants have. THAT is the concern.

It's great that the population is not growing and stabilized at 704 in my house, but the population growth isn't the real problem. It's feeding, clothing, supporting the extra 700 people.

That's the same problem with earth's population. Europe's population AND consumption boom the past 250 years wiped out 99% of all the flora, fauna, sea life on earth. China's population AND consumption boom the past 50 years wiped out the 99% of the remaining 1%. India's will do the same and most devastatingly, africa's boom will wipe out the massive herds and wildlife just like european expansion in americas wiped out the massive buffalo/bison herds, etc.

If the population stabilizes at 7 billion, we can somewhat manage if 6 billion would live a poor subsistence farming life where they consumed very little. But if the 6 billion wanted to live a life of luxury like the west ( and china has done so in the past 50 years ), then the environmental degradation will continue out of sheer demographic/economic fact.

Also, another issue is that our economic model is based entirely on continued population and consumption growth. This is why immigration/consumption is encouraged in the wealthy west. Our economy will collapse if the population/consumption doesn't increase. So if the world adopts our economic model ( which most of the has ), and the population stabilizes at 7 billion, then we will eventually have a world economic collapse as the population ages and the population pyramid inverts...

One thing that is interesting to consider when it comes to the rise in population is fertilizer. The Haber-Bosch process was developed by Carl Bosch & Fritz Haber to mass produce ammonia on an industrial scale back in the early 1900s. This resulted in more fertilizer for growing crops than would be naturally, and in turn more food to feed larger populations.

http://www.vaclavsmil.com/wp-content/uploads/docs/smil-article-1999-nature7.pdf

https://en.wikipedia.org/wiki/Carl_Bosch

The Haber–Bosch Process today consumes more than one percent of humanity's energy production and is responsible for feeding roughly one-third of its population.[4] On average, one-half of the nitrogen in a human body comes from synthetically fixed sources, the product of a Haber–Bosch plant.

Does anyone know why people have less children when they have better life conditions? I'm assuming it's because of education?

Does the data take into account of Scientists Prolonging the life span of Humans though?

De_tr0p · 6時間前

Overpopulation isn't something that can be understood or explained "in a nut shell" A lot of the data they used to get to the stated outcome is circumstantial, and not at all caused by forces that are universal or static.

There are way to many environmental variables on a global scale that just effect general mortality that make the data unreliable, without even bringing into account the complex human element variables.

Bill and Melinda gates foundation... This is a propaganda piece.

I don't want to spoil it, but 12 billion still is 5 billion more than we have today, and we already experience first overpopulation problems.

cookieman1 · 9時間前

I'm glad I now have a good video to show people overpopulation is not an issue. A surprising number of people claim it's the next big thing, while the statistics show the rate of population growth is slowing.

PYR0CHA0S · 6時間前

Couple things I don't see addressed:

He doesn't talk about nature's way to combat population increases, through disease or natural disasters
Life expectancy also rises with advancement of medical research and technology
It would be worth mentioning how China had put in a lot of efforts to reduce their population, intentionally and unintentionally, and the results of that.

Rad video. The majority of people don't realise how far we've come in battling poverty in the past few decades, but this perfectly shows our progress. One of the few Kurzgesagt videos where I'm not left with a sense of hopelessness and despair.

Oh and enjoy the juicy karma OP you slut ;)

This was a really good summary of population change and the demographic transition. I've taught population dynamics in a university setting and there are always a lot of misconceptions about population growth/decline. The demographic transition is generally considered to be an incredibly strong theory of social science so it's nice to hear it explained in a relatively simple way.

In my classes I've always taught that overpopulation is (now) not the worry, but rather consumption rates. A small number of people that wildly over-consumes can still create problems for sustainability. However, these problems can be somewhat averted through agricultural innovations and the move to renewable energy.

Ive recently being doing my Family tree and couldnt believe that just a few generations ago in the early 1900s my Great grandparents had 6-7 brothers and sisters who lived past 16 aswell as dozens of siblings who didnt even make it. compare that to now where each one of my parents siblings have 3 kids at most.

Interesting video but doesn't talk about the highest levels of consumption! More People more consumption and if its not done in a sustainable we will have serious problems.

SHITS_ON_OP · 4時間前

but this doesn't even address the problem... the problem with too many people is we're using too many resources... i know the population is going to level off at 10 billion but we've been over using our resources since we've had a population of like 3 billion

Wow this kind of blows my mind. It never occurred to me that population could stabilize. I always assumed we'd be overpopulated.

Awesome video if it's true!

This myth is often present in the "white genocide"/anti-islam discourse. You will find people claiming that islam going to take over Europe, because islamic countries have so many babies, and white europeans only a few. So it is just a matter of time until islam population overruns native europeans.

But the birth rate for immigrants is converging with the local population. Sadly, some people loves to ignore it, because their agenda desperately depends on talking about how low birth rates have been caused by "cultural degeneracy".

I am so glad Kurzgesagt took up this topic. It is one of my pet peeves to read these doomsday population growth comments on Reddit.
