Seven Billion

[disclaimer: this post appears just days after some friends of mine announce their pregnancy; this is a complete coincidence (this post was written and scheduled some time ago) and of course I’m delighted for the new parents-to-be]

In October, the world population is expected to reach seven billion. Seven fucking billion. I remember being a child and the media reports around the time that we hit five billion: that was in the late 1980s. When my parents were growing up, we hadn’t even hit three billion. For the first nine or ten thousand years of human civilisation between the agricultural revolution and the industrial revolution, the world population was consistently below a billion. Let’s visualise that for a moment:

World population for the last 12,000 years.

How big is our island?

Am I the only one who gets really bothered by graphs that look like this? Does it not cause alarm?

We have runaway population growth and finite natural resources. Those two things can’t coexist together forever. Let’s have a look at another graph:

Reindeer population on St. Matthew Island, from the comic of the same name.

This one is taken from a wonderful comic called St. Matthew Island, about the real island. It charts the population explosion of a herd of reindeer introduced to the island in the 1940s and then left to their own devices in a safe and predator-free environment. Their population ballooned until they were consuming all of their available resources. As it continued to expand, a tipping point was reached, and catastrophe struck: without sufficient food, mass starvation set in and the population crashed down from about 6,000 to only 43. By the 1980s, even these few had died out.

There are now no reindeer on St. Matthew Island. And it looks like this 40-year story could serve as a model for the larger, multi-century, world-wide population explosion that humans are having.

Game Theory

Humans are – in theory at least – smart enough to see what’s coming. If we continue to expand in this way, we risk enormous hardship (likely) and possible extinction (perhaps). Yet still the vast majority of us choose to breed, in spite of the overwhelming evidence that this is Not A Good Thing.

But even people smart enough to know better seem to continue to be procreating. And perhaps they’re right to: for most people, there is – for obvious evolutionary reasons – a biological urge to pass on one’s genes to the next generation. During a period of population explosion, the risk that your genetic material will be “drowned out” by the material of those practically unrelated to you. Sure: there might be a complete ecological collapse in 10, 100 or 1000 years… but the best way to ensure that your genes survive it is to put them into as many individuals as possible: surely some of them will make it, right? Just like buying several lottery tickets improves your chances of hitting the jackpot.

A stack of lottery tickets. If I buy enough, I’m sure to win, right?

On a political level, too, a similar application of game theory applies: if the other countries are going to have more people, then our country needs more people too! Very few countries penalise families for having multiple children (in fact, to the contrary), and those that do don’t do so very effectively. This leads to a “population arms race”, and no nation can afford to fall behind its rivals: it needs a young workforce ready to pay taxes, produce goods, pay for the upkeep of the retired… and conceive yet more children.

The same tired arguments

Mostly, though, I hear the same tired arguments for breeding [PDF]: cultural conditioning and social expectations, a desire to “pass on” a name (needless to say, I have a different idea about names than many people), a xenophobic belief that the world needs “more people like us” but “less like them”, and worry that you might regret it later (curious how few people seem to consider the reverse of this argument).

For me, the genetic problem is easy enough to fix: if your children’s genes are valuable to you because of their direct relationship (50%) to your genes, then presumably your brother’s (50%) and your niece’s (25%) are valuable to you to: more so than that of somebody on the other side of the world? I just draw the boundary in a different place – all of us humans share well over 99% of our DNA with one another anyway: we’re all one big family! We only share a lower percentage with other primates,  a lower percentage still with other mammals, and so on (although we still share quite a lot even with plants).

The similarity between you and your children is only marginally more – almost insignificantly so – than the similarity between you and every other human that has ever lived.

If you’re looking for a “family” that carries your genetic material: you’re living in one… with almost seven billion brothers, sisters, cousins, uncles and aunts! If you can expand your thinking to include the non-human animals, too, well: good for you (I can’t quite stretch that far!). But if you’re looking to help your family survive… can you expand that thinking into a loyalty to your species, instead, and make the effort to reduce population growth for the benefit of all of us?

My family tree. Have you met my great aunt baboon? Oh; sorry – that’s my sister before she brushes her hair on a morning…

The other argument I frequently see is the “replacement” argument: that it’s ethically okay for a breeding pair of humans to have exactly two children to “replace” them. This argument has (at least) three flaws:

  1. The replacement is not instantaneous. If a couple, aged 30, have 2 children, and live to age 80, then there are 50 years during which there are four humans taking up space, food, water and energy. The problem is compounded even further when we factor in the fact that life spans continue to increase. If you live longer than your parents, and your children live longer than you, then “replacement” breeding actually results in a continuous increase in total population.
  2. Even ignoring the above, “replacement” breeding strategies only actually works if they’re universal. Given that many humans will probably continue to engage super-replacement level reproduction, we’re likely to need a huge number of humans to engage in sub-replacement level or no reproduction in order to balance it out.
  3. It makes the assumption that current population levels represent a sustainable situation. That might or might not be true – various studies peg the maximum capacity for the planet at anywhere between one and a hundred billion individuals, with the majority concluding a value somewhere between four and ten billion. Given the gravity of the situation, I’d rather err on the side of caution.

Child sandwiches

“Do you not like children, then?” I’m sometimes asked, as if this were the only explanation for my notion. And recently, I’ve found a new analogy to help explain myself: children are like bacon sandwiches.

I’m sure I’m overusing this picture of a BLT.

Children are like bacon sandwiches for five major reasons:

  1. Like most (but not all) people, I like them.
  2. I’d love to have them some day.
  3. But I choose not to, principally because it would be ethically wrong.
  4. I don’t want to prevent others from having them (although I don’t encourage it either), because their freedom is more important than that they agree with me. However, I’d like everybody to carefully consider their actions.
  5. They taste best when they’re grilled until they’re just barely-crispy. Mmm.

Now of course I’ve only been refraining from bacon sandwiches for a few months: that’s why this is a new analogy to me… but I’ve felt this way about procreation for as long as I can remember.

The reasons are similar, though: I care about other humans (and, to a much lesser degree, about other living things, especially those which are “closer” family), and I’d rather not be responsible, even a little, for the kind of widespread starvation that was doubtless experienced by the reindeer of St. Matthew Island. Given the way that humans will go to war over limited resources and our capacity to cause destruction and suffering, we might even envy the reindeer – who “only” had to starve to death – before we’re done.

Insanity Clause

This was one of my most-popular articles in 2009. If you enjoyed it, you might also enjoy:

I believe that it is ethically wrong to lie to children about the existence of Santa Claus. And, as it’s a topical time of year – and because I know that this view brings me into conflict with the views of many others (I’ve certainly had more than a couple of arguments about this before) – I thought that I’d explain my thinking.

"I'm not real, but don't tell anyone!"
"I'm not real... but don't tell anyone!"

Bias of background

I probably ought to come clean, first, about my own background. There’s a certain bias that people can have towards their own upbringing: the implicit assumption that the way one was brought up is somehow the best or the most-correct way. I’d like to think that I’m speaking from a position of rationality as well as morality, but I can’t deny that my judgment may be clouded by my own childhood.

I never believed that Santa was real, and was never encouraged to. My family played out a whole variety of modern, secular Christmas traditions, such as leaving out a mince pie for Santa, hanging stockings, and decorating a tree. But these were always understood to be what they actually were. There was never an illusion that the mince pie wasn’t being eaten by my dad just minutes after he’d checked that I’d finally managed to curb my excitement get to sleep (even without a belief in the patently mythological, Christmas can still be an exciting time for a child).

What’s the harm?

When I was growing up, I came into contact with many children for whom the Father Christmas myth was very real. I gather that they’re still remarkably common… and who can blame parents: perpetuating the Santa lie can provide a very easy and pervasive way to control the behaviour of their children!

For the vast majority of these children, the revelation of the lie was a harmless experience: over time, they developed doubts, from the childish (“We don’t have a chimney? How can Santa slide down radiators?”), to the logical (“Reindeer can’t fly! And how big is a sleigh that can carry presents for every good child on Earth?”), to the profound (“Why does Santa give the children of rich parents more expensive gifts than the children of poor parents?”). They’d hear stories from other children about the falsehood of the Christmas stories when they spoke to other children or, often, older siblings. Many would eventually challenge their parents on these lies, and most of these parents would then come clean, correctly judging that the lie had run it’s course. So what’s the harm?

There are some children who didn’t come off so well. I’ve seen children bullied at school and in social settings as a result of clinging to their belief in Santa. One kid I knew – bolstered by his mother’s ongoing lies (she would later claim that she thought he knew, but was just “playing along”) – genuinely believed in Santa until he was 14 years old, defying all argument to the contrary, and suffered so much that he ceased to gain any enjoyment at all from the festival for years to come.

I’ve spoken to parents who have attempted to justify their decision to lie to their children by dismissing it as only “a white lie”, something which does more good than harm, and I can see their argument. But for some children, as we’ve seen, this lie can spiral out of control, and even if this were to happen with only one in a thousand children, I wouldn’t personally want to take the risk that it was a child of mine.

One of Santa's biggest benefits is that he has a list of where all the naughty girls live.

That Magical Christmas Feeling™

A common response to my claim that lying to children about Santa is ethically wrong is that there is something particularly special (or “magical”, it is often said) about being able to believe in Santa. Those who make this claim invariably come from a background in which they were encouraged to believe in him, and they frequently talk of wanting their children to be able to have the same experience as them. (I would speculate that there’s a large crossover between this group of people and the group of people who would rather their children were brought up with their religious beliefs, or lack thereof, than be given the opportunity to make their own choices, too).

Having experienced life as an a-santaist, I can say that there never for a moment felt like there was something missing from my childhood Christmases. Children have a rich and beautiful imagination and a way of looking at the world which will find wonder and magic, if they want it, regardless of the untruths they’re told. Imposing false beliefs as truths on healthy young minds does not result in a net addition of “magic”. At best, all that is achieved is that the child fantasies about a specific lie, perhaps one that the child’s caregivers can relate to. We’ve discussed a couple of the worth cases already, and these aren’t isolated incidents.

Christmas can be a magical time anyway. There’s time away from school (for children of schoolgoing age), a chance to see distant relatives, the giving and receiving of presents (how can I have left this until third in the list!), following unusual and exciting traditions, eating special food, the potential for snow (at least in this hemisphere), and a time for telling special stories and singing special songs. Special events are magical, and that’s true whether or not you subscribe to any particular religious or secular holidays. For a child, birthdays are magical, bonfire night is magical (ooh! fireworks!), the summer solstice is magical: whatever you’ve got can be magical when you’ve got a child’s imagination.

Think back to whatever family traditions you had as a child, especially the ones you had to wait a whole year for. They’re all special, all by themselves. You can enjoy eating delicious chocolate eggs without believing in either a magical rabbit with a confusing reproductive system, the crucifixion of the embodiment of a deity, or spring coming forth thanks to the earned favour of the fertility gods. Sorry, what were you saying? I was still thinking about chocolate.

Santana - a full 100% more real, but only 95% less magical - than Santa

So, no Santa at all, then?

If you were paying attention, you’ll have seen that I said “telling special stories and singing special songs”. My childhood was a secular one, certainly, but that doesn’t mean that it wasn’t full of stories of a jolly red man, songs about cervines with nasal photoluminescence, and so on. I enjoyed stories about a gift-giving magical man, just like I enjoyed stories about anthropomorphic talking animals: and it’s okay to understand these things for just what they are: stories! There’s perhaps something a little special in stories about Father Christmas in that they’re told pretty-much exclusively at Christmas time (and, perhaps, a little much – how many Christmas-themed movies are scheduled for television broadcast this winter?), but we don’t have to treat them as if they’re real.

My rules are pretty simple. If you (a) know something to be false and (b) teach it to a child to be real with (c) the intent for them to believe it wholeheartedly and for an extended period of time, you’re abusing the position of trust in which that child has placed you. (a) provides an exception for religious upbringing, (b) provides an exception for relationships in which there is not a disparity of power, and (c) provides an exception for whatever so-called “white lies” you feel that you need: that’s a pretty hefty lump of exceptions, if you need them – but still people raise objections.

Here’s what Santa means to me. To me, “Santa” is, and has always been, the embodiment of anonymous gift-giving: the genuine “spirit of Christmas”, if you like. And given my way, that would be what I’d want to teach my children, too. I’m not for a moment denying anybody the magic of the season, I’m just saying that there’s a big difference between Santa as an abstract concept (like a storm “wanting” to break) and Santa as a real, albeit magical, being (like Poseidon sending the storm).

It’s a matter of trust

For me, this all comes down to trust. I don’t want to lie to my children. It’s not a difficult concept to understand: the only difference between me and a large number of other people is that they choose a different definition of “lie”. For the virtually all children who discover that they’ve been deceived about Santa, their trust in their parents remains fundamentally unharmed. For some, it’s dented for a short while but then comes back. But this still doesn’t make it right.

I want to be somebody who my children will always know that they can trust. I want them to know that I will not lie to them or deceive them. I want to be somebody who they can turn to for advice. I want to be somebody who they know will put them first, even in spite of tradition and convention.

That’s where I stand. Let’s here what you guys think.

Now this is the kind of Santa that I can get behind.

But first, there’s one more argument…

…that I’ve heard recently. I’ve heard it put that it’s beneficial to lie to children about Santa because it teaches them not to trust everything they hear, teaches them to be critical thinkers, etc.. That being taught a lie will toughen them against other lies that they will be given to them later in the big, wide, and cruel world.

This argument holds no weight with me. Do these same parents like to beat up their children “just a little” so that if they get into a fight at school, it won’t be so bad? Do they lock up and abuse their kids so that if they’re kidnapped and raped that it isn’t so hard on them?

In my mind, a lie that you keep up for years on end is no longer a harmless lie. When I want to teach my kids about deceit, I’ll perform magic tricks for them. The first time you perform a magic trick for a child, they genuinely believe it – how did he make that coin appear from behind my ear? Leave it for a minute or so (a minute can be an eternity when you’re a kid). Then I’ll show them how it’s done. I’ll teach them to do the trick themselves, and they’ll see for themselves that magic is an illusion. Plus, they’ll have learned a cool trick.

The world is full of many very clever illusions and tricks, and often you can’t see how they’re done, but that doesn’t mean that they’re magic. There’s no shame in not knowing all the answers, but looking for answers is a noble and beautiful thing. I want to foster in my children a natural suspicion of magic, so that they’re better-able to avoid being conned by those who would do them harm. And I can achieve this without lying to them for more than a few minutes at a time. Shove that in your stocking, Santa.

“Daniel nearly 22 months”

This photo, taken 2 October 1982 and showing me at just 22 months old, might be the oldest picture of myself that I own on which I can pin a specific date. (Obviously) I didn’t start blogging until much later: my first real “blog” began in late 1998; this photo was posted here retroactively on 25 May 2019.
