Too Many People

By Nancy Jane Moore

There’s nothing like living through a severe drought accompanied by disastrous nearby wildfires and the hottest summer on record to get one thinking about climate change and access to water. So over the last couple of weeks I read Alex Prud’homme’s book The Ripple Effect. It provides an excellent overview on the water problems facing the world right now.

As I read, I kept coming back to one basic thought: This wouldn’t be such a problem if we didn’t have too many people on this planet.

My father just turned 93. When he was born, there were about 1.8 billion people on this planet. Today we’re pushing 7 billion — more than 3.5 times as many people. If he lives a few more years, the population will have quadrupled in his lifetime. Any way you look at it, that’s an extreme change in a short period of time.

Paul Ehrlich warned about this back in 1968, when his book The Population Bomb came out. It’s been fashionable for the last 20 years or so to bash Ehrlich for being wrong because some of his most drastic predictions didn’t come true.

As someone who sees the connection between overpopulation in everything from resource shortages to traffic congestion, I wondered why this was so, so I went down to the excellent Austin Public Library and checked out a copy.

Reading it was kind of like reading Golden Age science fiction for its predictive aspects: Some of the specifics were wrong, but the core point was right.

We may not have our jet packs and, alas, the space program has not made the progress we might have hoped for 60 years ago, but I’d be glad to argue that we’re living in the world predicted by the Golden Age writers.

Likewise, the disasters didn’t happen as Ehrlich and other population biologists predicted — I remember my freshman biology professor Michael Menaker telling us it was “too late” to do anything about India — but that doesn’t mean we haven’t had some terrible famines and other disasters, nor does it mean that overpopulation isn’t a major part of the crises we face right now.

Think about this: If the Earth’s population right now was the 3.5 billion we had when Ehrlich first published The Population Bomb in 1968, would we be putting such a strain on water resources? Would we be putting as much carbon dioxide in the air? Would we need as much oil? For that matter, would unemployment and immigration be such problems? With fewer people, we might have jobs going begging and need immigrants to fill them.

We have famine going on right now; it’s particularly bad in Somalia. As Rose George pointed out in her excellent book, The Big Necessity, 2.4 billion people on this planet do not have access to any kind of toilet — not even an outhouse.

Now it happens that I have a decent life. I’ve got a place to live, a car, a job, and enough money in the bank to not only take care of my basic needs, but also to splurge on books or high tech tools or art or travel when I get the urge. I even have time to spend on my own work.

It seems to me that everybody on Earth should have the opportunity to live as well as I do. But if all 7 billion had lived at least as well as I have for the past decade or so, climate change alone would have made the planet close to uninhabitable by now.

One of the rebuffs to Ehrlich has been that technology can fix things. And that may be true: there are certainly some technological solutions that will make life on an Earth with 7 billion people more feasible. But looking at the pace of population growth and the pace of technological change in such things as clean energy, mass transportation, and efficient use of water, I don’t see the technology changing fast enough to prevent either massive human suffering or significant changes to our climate.

As a rule, I’m not a believer in apocalypses, whether predicted by religious fundamentalists, ancient Mayans, or environmentalists. I tend to a belief that human beings will find a way to muddle along. But the more I look at climate change and overpopulation, the more I think there are going to be some major collapses over the next century, and maybe even for some centuries beyond.

I hope I’m wrong, because I also see the potential that human beings will actually make progress at becoming a civilized species. The possibilities presented by both the digital revolution and the growing understanding that all people on Earth are connected and that society works best when we cooperate give me hope even as climate change makes me despair.

As a writer, I’ve been approaching this subject by writing stories in which societies collapse and climate disaster happens, but civilization manages to survive — that is, we don’t send ourselves back to the Stone Age. “Or We Will All Hang Separately” is an example — one I hope to expand into a novel in the next couple of years.

I don’t know what the optimum population of Earth is in the abstract. For me, it’s a planet where the air is clean, we have plenty of water, there’s enough space for privacy, and there’s still some undeveloped wilderness out there for me to visit (not live in).

It’s a matter of perspective, though.

Crazy Horse thought there were too many people in the world — or at least, on the Great Plains and in the Black Hills — 140 years ago. Back then there were about a billion people on Earth, but an awful lot of them wanted the gold in the Black Hills.

Could be that whatever number of people we end up with will be too many so long as humans continue to be greedy.

Too Many People — 5 Comments

  1. Yes, technology will allow Earth to support a much higher population than what we have now, but I, for one, don’t want to live in a cracker box or eat styrofoam.

    Hm, there’s a lot of people without toilets over there and a lot of people without work over here. Hm. Smells like opportunity to me. Now that we’re globalized seems we could ship some workers over there to get those toilets dug.

    Nice point about science fiction relevancy.

    Great post, Nancy. Keep reading and reporting. I like to hear you talk.

  2. Have you seen the discussions about whether we are now in the Anthropocene Era? The age in which man and his works changes the earth. Here’s one link: http://www.nytimes.com/roomfordebate/2011/05/19/the-age-of-anthropocene-should-we-worry

    In addition to the various apocalypse fictional possibilities, there’s always the Doing-Something-About-It school of fiction. The poster boy for this would be Ra’s al Ghul, the comic book villain, whose idea is that, yes, there are too many people on this planet. His plans to fix this, usually by offing large swathes of his fellow man, are of course continually combated by Batman.

  3. Thanks, Sue. One of the things I like about blogging is the opportunity to talk about things that are bothering me.

    Brenda, I’m all for “doing something about it,” but I’d like to see non-villains coming up with something not evil as a solution. I’ve got a couple of friends who keep coming up with ugly disease scenarios, but I hope there can be some civilized solutions.

  4. I forget which Asimov novel it was, where humanity had essentially handed over management of Earth to a gigantic computer. One character says to the other that for all humanity knows, the computer will conclude that mankind will be happiest as hunter-gatherers, and will set about leading humanity there. Since the computer mastermind was still bound by the Three Laws of Robotics, this was of course not going to involve wholesale slaughter. Presumably depressing the birth rate would do it, combined with astutue management.

  5. Great post. Among the many problems is that there is no method for allocating (or saving) precious resources on a international level. Or a national level. Or, in Texas, on a state level. As the noose draws tighter that lack will be felt more and more.

    Now to find a copy of The Ripple Effect.

    P.S. How do you have time to do all this?
