Readers of this blog will know that I have come to some big-picture conclusions about success and failure that are unsettling. I don’t like them myself. Not only do they create an inner sadness about where I think the human endeavor is heading, but they result in a sort of isolation that I would rather not suffer—introvert though I am. Among other academics at my institution, it is rare for me to find kindred spirits, even among groups self-selected to care about environmental issues. Most don’t seem to see very far beyond climate change in the lineup of existential threats, increasingly focusing on inequities within the human population that stem from climate and environmental disturbances. I am glad that climate change awareness is high (a genuine threat), but even if climate change had never arisen, I think we would still be in grave trouble from the more fundamental flaws in our explosive approach to living on Earth.
This is a large part of the impetus behind PLAN, which I announced in the last post. Already, I am gratified that people joining the network from vastly different fields and experiences have formed similar conclusions at the highest level. So I’m not crazy, unless we all are. In any case, I am less lonely. [I will say that crazy is usually easy to spot in conversation: a little too insistent/enthusiastic/one-track. The PLAN folks feel really solid, broad, and even perhaps subdued to me: not the type you want to back away from at a party.]
But I still try to understand why so few of my colleagues have reached similar conclusions. The easy answer is that I’m just plain wrong. But believe me, I have tormented myself to try to discover the missing piece and go back to being a happy human bumping along in this race to who-knows-where. It’s not that my unconcerned colleagues have thought more deeply about the issues and can help a rookie out, in my experience.
In this post, I venture some guesses about the disconnect—some of which may even be on target. I will loosely frame the discussion in the context of academia, but much of the logic also applies beyond this scope. The basic idea is: complexity makes it hard to differentiate between real and artificial worlds.

Purveyors of unpopular messages are often scrutinized for any inconsistent, seemingly hypocritical behavior that might give lie to their preachings and be used to discredit the unwelcome perspective. A famous example is Al Gore’s heavy air travel schedule to spread the word and take action against climate change, resulting in an enormous CO2 footprint. If we all behaved that way, the very problem at hand would be substantially exacerbated.
Such accusations either knowingly or pathetically miss the obvious point that the net effect of Al Gore’s efforts may be positive owing to the simple idea of a lever: a little expenditure here can counteract vast expenditures elsewhere for an overall gain on the problem. For many, the glaring superficial contradiction is enough ammunition to discredit the entire enterprise.
But identifying possible hypocrisy in those who warn of future perils, as I have done, has a dark edge: if even those cognizant individuals cannot get away from behaviors they know to be damaging, doesn’t that only amplify the severity of the warning?

Recent reflections on the long-term trajectory of the human enterprise have somewhat transformed the way I look at most activities. Specifically, I refer to the dual realizations that on 10,000 year timescales ultimate success is effectively synonymous with true sustainability, and that the human race stands in blatant breach of contract with evolution and ecosystem parameters—fueled by a mad grab of one-time finite resources. The net effect is that most human activities today promote ultimate failure rather than ultimate success.
As such, when evaluating a proposed or ongoing effort, I ask myself the question:
To what end?
This post will examine some of the activities of current society, and evaluate how much sense they make in the context of a post-party future.

A 2018 paper by Bar-On, Phillips, and Milo in PNAS contains a fascinating figure (Figure 1) that bears staring at for some time. It shows the dry carbon biomass distribution of various forms of life on Earth. Plants account for 450 Gt (giga-ton; 1012 kg) of mass, while the sum of all animals adds to 2.5 Gt. Humans comprise only 2.4% of animal mass on the planet, but that’s almost ten times as large as wild mammal mass. Add human livestock (outweighing human mass) and wild mammals are only 4% of the human-livestock-mammal trio.
But this post is heading somewhere else: lament about the un-wilding of the planet on your own time (kidding aside, please do!). Let’s start by considering the following question. Which do you think is more valuable: the web of living animals on this planet, or all the gold accessible in the ground? If given a choice to eliminate one and preserve the other, which would you choose? Gold, among Earth’s mineral stocks, is used for this question because it has served as a physically-based monetary standard for many cultures throughout time.
What follows has absurd elements to it, but hopefully in forgivable service of a larger point about the value of life on this planet and in shining a glaring spotlight on current human values.
One of the prevailing narratives of our time is that we are innovating our way into the future at break-neck speed. It’s just dizzying how quickly the world around us is changing. Technology is this juggernaut that gets ever bigger, ever faster, and all we need to do is hold on for the wild ride into the infinitely cool. Problems get solved faster than we can blink.
But I’m going to claim that this is an old, outdated narrative. I think we have a tendency to latch onto a story of humanity that we find appealing or flattering, and stick with it long past its expiration date. Many readers at this point, in fact, may think that it’s sheer lunacy for me to challenge such an obvious truth about the world we live in. Perhaps this will encourage said souls to read on—eager to witness a spectacular failure as I attempt to pull off this seemingly impossible stunt.
The (slightly overstated) claim is that no major new inventions have come to bear in my 45-year lifespan. The 45 years prior, however, were chock-full of monumental breakthroughs.

I started Do the Math in 2011 as a way to reach a larger audience than a handful of students every year or two in an energy course at UCSD. I had (and still have) deep concerns about the assumptions we make as a society based on our fossil fuel trajectory over the last century or so. Trying to steer policy from the top seemed a losing proposition: feckless politicians hew to their constituents’ desires via a mechanism we call democracy, so why not try to get people on board directly?
I never imagined creating a blog that would get millions of pageviews, although this by itself falls well short of having an impact on a grand scale. But I figured I owed it to myself to reach as many as I might. What I have found is that a select few seem to share my concerns. And some vocal contributors to comments strongly disagree that we need to worry (why then make the seemingly wasted effort to respond to—in their eyes—doomsaying kooks if in fact we need not be concerned?). But most people simply don’t care enough to tune in. They’ve learned to ignore prognostications of any flavor, perhaps. Lately, even fewer people are entertaining ideas of resource limits owing to increased global oil production (led almost entirely by U.S. shale oil) and a recovering economy.
But I think there is something more fundamental going on here. I think we’re dealing with personality traits cooked into human nature. Are we capable of mitigating a far-off potential calamity via proactive efforts decades ahead of a putative crisis? In this post, I’ll use some survey data suggesting that we may be in trouble.
I should have done it right the first time. I now realize that I’m hungry for a tiny bit more information in relation to personality type. I have had almost 500 responses to the previous query (see previous post, below). The results are fascinating. I have added two quick questions that will give me a fair bit of insight into some key systematic issues.
Even if you have answered the poll already, I would appreciate a quick moment of your time to answer two additional questions (click here). It requires very little time: especially if you responded to the first survey request.
If you did not respond to the first survey, please do this one.
Instructions appear on the survey page for how to determine your Myers-Briggs type, if you do not already know it. Thanks for your patience, and look for a post in mid-April with the jaw-dropping results.
I have a new post written up, but thought that before I release it I should get some delicious new data.
To that end, please take this single-question bare-bones survey (link decommissioned; see this post) about your personality type. There are sixteen choices in a drop-down menu according to the Myers-Briggs personality type indicator. If you do not already know your type, you can find free online versions. While I have no particular affinity for this specific one, it may be good for the sake of uniformity that you go take this one. It’s 72 yes/no questions (should take 5–10 minutes).
Just remember to be honest and answer for the person you are, rather than the person you may aspire to be (if different).
And don’t forget in your excitement to indicate the outcome on my lighting-fast survey (link decommissioned; new survey here).
I’ll let you know what it’s all about shortly.
The holiday season is upon us, and for many, this translates into a marked uptick in the consumption of tasty food treats. I’m no different, and can really pack it in on such occasions. For instance, the day after Thanksgiving this year, I stepped on the scale to find myself about 5 pounds (~2 kg) above normal weight. I kicked in my diet plan, and by Monday morning (3 days later) I was back to normal. Resume course. I use a simple formula, backed by physics, that works every single time. The topic is Do-the-Math-relevant for two reasons: it applies quantitative physics to everyday life, and it touches on attitudes relevant to energy/resource conservation.

Sometimes considered a taboo subject, the issue of population runs as an undercurrent in virtually all discussions of modern challenges. Naturally, resource use, environmental pressures, climate change, food and water supply, and the health of the world’s fish and wildlife populations would all be non-issues if Earth enjoyed a human population of 100 million or less.
The subject is taboo for a few reasons. The suggestion that a smaller number would be nice begs the question of who we should eliminate, and who gets to decide such things. Also, the vast majority of people bring children into the world, and perhaps feel a personal sting when it is implied that such actions are part of the problem. I myself come from a long line of breeders, and perhaps you do too.
Recently, participating in a panel discussion in front of a room full of physics educators, I made the simple statement that “surplus energy grows babies.” This is motivated by my recognition that population growth bent upwards when widespread use of coal ushered in the Industrial Revolution and bent again when fossil fuels entered global agriculture in a big way during the Green Revolution. These are really just facets of the broader Fossil Fuel Revolution. I was challenged by a member of the audience with the glaringly obvious statement that population growth rates subside in energy-rich nations—the so-called demographic transition. How do these sentiments square against one another?
So in the spirit of looking at the numbers, let’s explore in particular various connections between population and energy. In the process I will expose the United States, rather than Africa, for instance, as the real problem when it comes to population growth.
