I did an event with environmental journalist (and personal hero) Elizabeth Kolbert in September 2017, in which we discussed various matters related to journalism and climate change. Subsequently, one of the attendees wrote and asked why I hadn’t talked about population. Isn’t overpopulation the real root of our environmental ills?

Anyone who’s ever given a talk on an environmental subject knows that the population question is a near-inevitability (second only to the nuclear question). I used to get asked about it constantly when I wrote for Grist — less now, but still fairly regularly.

I thought I would explain, once and for all, why I hardly ever talk about population, and why I’m unlikely to in the future.

 world population
(Worldometers)
Math confirms that population is indeed a factor in environmental impact
Human impact on the natural environment is summed up in a simple formula:

Impact = Population x Affluence x Technology

All are rising. (Bill Gates has a slightly more complicated formula related to carbon dioxide, but P is a variable in his too.)

The current global population has crossed 7.5 billion and is heading upward. The latest UN projections have it hitting 8.6 billion by 2030, 9.8 billion by 2050, and 11.2 billion by 2100. Average fertility rate will decrease, but that effect will be overwhelmed by the absolute numbers. (There are many arguments out there that UN is overestimating population growth, but let’s stick with their numbers for this post.)

The UN expects over half the growth out to 2100 to be concentrated in just nine countries, listed here in order of their expected contribution:

India, Nigeria, the Democratic Republic of the Congo, Pakistan, Ethiopia, the United Republic of Tanzania, the United States of America, Uganda, and Indonesia.

Most of those people will be fairly poor (by Western standards, though hopefully less so than their forbearers), which means their per-capita consumption of resources will be fairly low. Nonetheless, cumulatively, adding 2.3 billion people by 2050 amounts to enormous additional resource use and pollution (including greenhouse gases).

Mitigating some substantial percentage of that population growth would be one way to better environmental conditions in 2050. It would also have more impact than virtually any other climate policy. (More on that later.)

However. That human numbers are, axiomatically, part of the story of human impact does not mean that human numbers have to take center stage. Talking about population growth is morally and politically fraught, but the best ways of tackling it (like, say, educating girls) don’t necessitate talking about it at all.

Tackling population growth can be done without the enormous, unnecessary risks involved in talking about population growth.

Population’s unsavory associations
When political movements or leaders adopt population control as a central concern ... let’s just say it never goes well. In practice, where you find concern over “population,” you very often find racism, xenophobia, or eugenics lurking in the wings. It’s almost always, ahem, particular populations that need reducing.

 Eugenical Sterilization Map of the United States, 1935; from The Harry H. Laughlin Papers, Truman State University
Eugenical Sterilization Map of the US, 1935 (PBS)
History is replete with examples, but perhaps the most germane recent episode was less than 20 years ago, at the Sierra Club, which was riven by divisions over immigration. A group of grassroots members, with some help from powerful funders, attempted to take over the national organization.

These members advocated sharply restricting immigration, saying the US should be reducing rather than increasing its population. Their contention is that the country’s open immigration policies are hurting the environment by bringing in poor immigrants and making them richer, thus increasing their environmental impact. Of course, they swore up and down that xenophobia had nothing to do with it.

The Sierra Club won that fight, and the “green anti-immigrant” movement has mostly been driven to the fringes, but conservative media is still getting ratings out of it. If you can stomach it, watch this entire segment with Tucker Carlson of Fox News — it hits all the usual notes, culminating in an interview with some professor who wrote a book about reducing immigration for environmental reasons.


I don’t doubt that it’s possible to be concerned about the environmental stresses population brings without any racism or xenophobia — I’ve met many people who fit that description, and there were well-meaning (if quite mistaken) population-focused groups in the ’70s and ’80s — but in terms of public discussion and advocacy, anyone explicitly expressing that concern starts out behind the eight ball. The mere mention of “population” raises all sorts of ugly historical associations.

Public health groups have largely cottoned to this. Even the ones that have “population” in the name focus on family planning rather than population as such. They’ve figured out something important — something not all greens have figured out — which is that the best ways to address population don’t necessarily involve talking about it at all.

So what are those ways?

There are two ways of looking at the problem of growing population on a finite planet. Depending on which you think is most important, there are different ways to address it, none of which require discussing population.

Female empowerment is the most effective carbon mitigation strategy
The first way to look at population is as a pure numbers game. More people means more consumers and more emitters, so the thing to do is slow the rise of population. Specifically, since most of the new people are going to come from poor or developing countries, the question is specifically how to slow population growth there.

Luckily, we know the answer. It is family planning that enables women to have only children they want and choose, and education of girls, giving them access to income opportunities outside the home. We know that women, given the resources and the choice, will opt for smaller families.

Those are the two most powerful levers to bend the population curve. They are also, in and of themselves, an enormously powerful climate policy. When Paul Hawken and his team investigated and ranked carbon-reduction solutions for their Drawdown project, they found that the combination of the two (call it the female-empowerment package) carried the most potential to reduce greenhouse gases later this century, out of any solution. (Together they could prevent 120 gigatons of GHGs by 2050 — more than on- and offshore wind combined.)

 family planning
Family planning: fewer, better cared for. (Drawdown)
So if you are concerned about the growth in population, make yourself a champion of female empowerment in the developing world. You will be contributing to the most effective solution to the problem without any of the moral baggage.

And next time you’re at an environmental event, maybe instead of asking the population question, ask the female empowerment question. Why aren’t climate hawks talking about it more? They should be!

Some population units consume and emit more than others
If your concern is the creation of new consumers and emitters, your gaze should be drawn to those who will consume and emit the most, i.e., the wealthy.

 unequal emissions
(Oxfam)
One way to prevent the creation of new high-consumers would be to persuade the wealthy to have fewer babies and to close off the borders of wealthy countries, preventing low-consumers from immigrating and becoming high-consumers. You could try, in short, to engineer population decline in wealthy countries.

That seems ... fraught.

For one thing, fertility tends to decline with wealth anyway. For another, any targeted attempt to engineer population decline is going to run into an unholy thicket of moral and political resistance.

Another way to approach the problem would be, rather than prevent the birth of extremely wealthy people, prevent the creation of extremely wealthy people. In other words, prevent the accumulation of massive wealth. You could do that by, for instance, taxing the shit out of wealthy people.

If you approached the problem that way, under the banner of reducing global income inequality, you would find many allies. Income inequality is a top-line concern of people and organizations all over the world, even some conservatives these days.

Reducing high-end consumption could have an enormous short-term impact on carbon emissions, as climate scientist Kevin Anderson is always saying. Shifting wealth within populations — reducing the number of very wealthy and the number in poverty — can have as much carbon impact as reducing overall population.

So maybe, at the next environmental event, you could ask the income inequality question rather than the population question.

There’s much downside and not much upside to talking about population
So that, for the record, is why I hardly ever talk or write about population. (I will now send all future askers of the population question to this post.) It is high risk — very, very easy to step on moral landmines in that territory — with little reward.

And where talk of population control is rarely popular (for good reason), female empowerment and greater equality are a) goals shared by powerful preexisting coalitions, b) replete with ancillary benefits beyond the environmental, and c) unquestionably righteous.

So why focus on the former when the latter gets you all the same advantages with none of the blowback? That’s how I figure it anyway.

You win this thread because that's most unsettling to even think about.

Don't wanna read all those words (pole dancing again?), but the title of the thread is important.


Watever fucking of the environment we're doing is pretty much overpopulation.
It's time to start culling.

A fraction of the population could still do the same amount of damage. There's plenty of space and resources to support the population, and the majority of environmental harm comes from industrial waste.

Educate girls and give them choices and opportunities. The only thing that works in controlling population apart from war and genocide and stuff.

I also don't agree. Overfishing, land use, preference for food species causing
an extinction event: it's all environmental harm on a massive scale.


Remember, pre-industrial human activity destroyed much of the med region and the Near East.

Pretty sure have read before, over two thirds of environmental damage stems from energy production alone. That's not to say the average person shouldn't do their part in being ecologically aware, but the general public have been duped into believing consumers are the problem, and that attitude distracts from the reality and avoids changes in production.

Not sure if you're trying to prove my point about a fraction of the population, since the world population is ten time greater now than it was in 1700.

What is the "med region"?

Meh. You know me better than that. My knowledge is usually from crap I don't have access to.




But, here's an extreme take on it (which I don't agree with the title of - the Sahara is quite old): http://www.dailymail.co.uk/sciencetech/article-4315796/How-humans-created-Sahara-desert-8-000-years-ago.html


If you don't know about the expansion of the Sahara and the deforestation of the Near East, I'm not being paid
to teach you.  It's pretty much the establishment view of the evidence.


Turns out that there are some arguments against though: https://www.astrobio.net/news-exclusive/how-earths-orbital-shift-shaped-the-sahara/

I believe the number touted most often is ninety per cent.

Earth is over populated by ninety per cent, some say.
I think that is a bit strong. I believe that with the "wisdom" we have established assuming due diligence from all, the earth could easily ignore a human population of thirty per cent of its current load.

Still means that about five billion people will have to cease to exist.

I don't buy it. The current mass extinction event predated industrialization and the intense population that it sustains.


Somewhere around 500 million - while still capable of massive environmental damage (we're looking at {probably way}
less than 200 million during the destruction to the med region) - anywhere above this is when the damage really
started to accelerate.  That gets us to pre-industrial numbers. If we can maintain a technological society with that
footprint, I would have high hopes for humanity.




And, it's not like we'd need to do a mass kill off. There's a tipping point (and we may be over it) where Methane stores will render
global warming likely to finish off this iteration of society, but if we could do the politically untenable things like cutting emissions,
reducing industrial meat production, ect, in conjunction with mass sterilization, the overall cost would be lower. But, humanity's
responses aren't designed for such foresight. The species would need to undergo a massive transformation - which is probably
impossible without calamitous (for us) natural goads. Evolutionary 'advancement' is a craps game.

There isn't really any need for mass killing or forced sterilisation.

Look at the EU. The average fertility rate is 1.6 and that is with governments still encouraging people to have more babies. And with large numbers of new immigrants who are having far more children than the indigenous populations.

In most developed countries 2 children is already considered "more than enough". Factor in that some people will opt out of having children altogether, or be unable to have children, or too dysfunctional to find someone to have children with, or stop at one.... your overall fertility rate drops to something like 1.5. Less than that in Japan. 1.24 in South Korea or Singapore. It can be done.

Population growth is largely a function of poverty and lack of opportunity.

Reduce the population by 20% every generation and within a century or thereabouts your population is current-population * 0.8^4 = about 40% of your current population.
