Tikopia




Tikopia (tik-o-PEE-a) is a wee island in the Pacific, quite close to the middle of nowhere, the remains of an ancient volcano.  Its area is 1.8 square miles (4.6 km2), much of it steep rugged hillside.  The closest neighbors live on Anuta, 85 miles away (137 km), a long and dangerous voyage in a dugout canoe.  Tiny Tikopia is eleven times larger than Anuta. 

Humans arrived in Tikopia maybe 3,000 years ago, and brought along pigs, dogs, fowl, rats, and the seeds of Polynesian foods.  For a while, folks ate well, dining on the abundant birds, fish, and shellfish.  As abundance faded, slash and burn agriculture gained momentum.  Deforestation crept up the slopes, and eroded soils washed down, accumulating near the shore.  Efforts were made to stabilize and expand the shoreline.  As a result, Tikopia’s land area is now 40 percent larger, and the reef area is 41 percent smaller.  There is much more land suitable for raising food.

The crater of Tikopia’s volcano used to be a saltwater bay linked to the sea, home to plentiful fish and shellfish.  Soil deposits have now blocked the connection to the sea, turning the bay into a lake.  This sharply reduced the marine life that formerly thrived in the bay.  The villages that depended on this food were screwed.  Around 1700, they exterminated a village having fertile land.  Another village fled in fear, paddling into the ocean, almost certainly drowning.  Conflict is hunger’s shadow.

The lake water is too salty to drink, as is the ocean.  Drinking water is obtained from springs flowing out of the hillsides, coming from sources above the villages and latrines.  Ashes, excrement, and kitchen wastes are used to return nutrients to the gardens and orchards.

Over time, folks planted more food-producing trees.  Eventually, they developed a clever three-story system of arboriculture, mixing tall, medium, and short tree species.  These included bananas, papaya, coconuts, sago, chestnuts, and almonds.  On the ground, they grew root crops, like taro, sweet potatoes, yams, and manioc.  This system maximized food production, reduced erosion, enriched the soil, was less vulnerable to cyclone damage, and did not require endless toil.  Pigs swiped too much human food, and were eliminated before 1800, as were the dogs.

Nature kept life interesting by sending drought years and frequent cyclones.  These could hammer the food supply.  Because Tikopia was so far from anywhere, importing food from elsewhere was not an option.  Folks preserved calories for famine years in two ways.  (1) They dug pits and fermented taro, breadfruit, and manioc into glop called masi, which could be stored for several years.  (2) The pith of the sago palm was dried and ground into storable flour.

Each house was assigned specific garden plots and orchards that comprised their primary source of nutrition.  If you ran short, you starved.  Carrying capacity expanded and declined in synch with food production.  When conditions got tight, older males in the household would set limits on reproduction.  The families complied, because everyone understood the painful consequences of having too many mouths to feed.

Because it encouraged social stability, population management was intelligent and ethical.  It was done in several ways.  Junior members of the family might be expected to remain bachelors or spinsters.  Everyone practiced coitus interruptus.  Efforts were made to induce miscarriages to end unwanted pregnancies.  Newborns were promptly suffocated.  It was usually OK to have two sons, but subsequent male offspring were strangled, to avoid conflicts over land inheritance.  Unmarried males sometimes jumped into a canoe and never returned.  Others swam out into the open sea and fed the sharks.  When all options failed, it was time to fetch clubs and go on the warpath.

I invite you to watch The Island of Tikopia, a pleasant 53-minute video.  It shows us cool people living in a tropical paradise.  Tikopia is blessed by being tiny, isolated, unsuitable for industrial agriculture, and having no valuable resources.  Hence, they have not been obliterated by modernity.  They will never suffer from automobiles or cell phones.  Even today, Tikopians live in functional communities, and enjoy an easygoing way of life that is unimaginable to frantic consumers thrashing through life in Crazyland.

The video does not focus on how contact with civilization has impacted their society.  On a different island, the Sentineli welcome all visitors with a shower of arrows.  They have learned from painful experience that outsiders can be bad juju.  Tikopians had no fear of visitors, because anyone who paddled in was a mellow islander like themselves.  Whites were different; following a visit in 1828, a quarter of the population died from disease.

Missionaries began to wash ashore in 1857, occasionally visiting the island.  Within 50 years, they had made a few converts.  Half were baptized by 1928, and by 1955, most were nominally Christian.  Chiefs who agreed to be baptized were rewarded with metal axes, knives, adzes, and other amazing stuff.  Heathens who preferred the ancient path were rewarded with self-righteous intolerance.

More destructive than dysentery, pneumonia, measles, and influenza was the deliberate introduction of European morality.  Much of the traditional culture managed to survive, but Christians were especially uptight about sex, family planning, and which deity to worship.  Naturally, the stern prohibition of premarital sex was disregarded by almost all youths, including horny young Christians.

Naturally, the mission’s opposition to population control had negative results.  Population soared 37 percent from 1,288 in 1928 (too many), to 1,753 in 1952 (way too many) — just in time for a devastating cyclone, and a bloody plunge into helter-skelter.  This drove anthropologist Raymond Firth crazy.  Christian culture was obsessed with compulsory conformity, but disinterested in the predictable results.  Tikopians had evolved a remarkably competent culture that adapted to the ecosystem and mindfully lived within limits.  Leave it alone, he shouted.

Anyone who has studied European history knows that this irrational morality of unrestrained growth has, over the centuries, led to the death of hundreds of millions via wars, famines, and epidemics.  Is this truly more ethical than intelligent family planning?  The principles of carrying capacity and overshoot apply to both tiny islands and the entire planet, as we are now in the process of discovering.

When the first humans arrived in Tikopia, there were no mammals.  There were no wild herbivores to freeload on their food supply.  The only man-eating predators were sharks, which swam outside the reefs.  In the absence of large predators, humans were the dominant animal.  There were no lions, jaguars, or hyenas to provide essential population control services.  Thus, a culture of mindful restraint was the preferred path to sustainability.

Today, Tikopia is one of 900+ islands in the nation of Solomon Islands, which is 95 percent Christian.  The Tikopian population crisis has been addressed by sending folks to establish colonies on other islands — islands that have been depopulated via exposure to the diseases of civilization.  Other Tikopians enjoy rewarding careers in manual labor at coconut plantations on larger islands.  How much longer can the consequences of European morality be sidestepped?  Sea levels are rising, cyclones are intensifying, and low-lying islands in the Solomons are vanishing.  Good luck islanders!

The Population Explosion


Following the publication of The Population Bomb in 1968, the new predicament of overpopulation was inducted into our gruesome mob of predicaments.  World leaders snapped to attention, contemplated their options, realized that promoting population control was political suicide, and chose to step around the messy issue.  The house was not on fire today, just some smoke.

The big exception was the Chinese, whose one-child program successfully prevented 350 million births.  It was sometimes heavy-handed, but ignoring runaway growth would have guaranteed a super-heavy disaster.  China had the same amount of cropland as the U.S., but four times the population, and the cropland was wearing out after centuries of organic farming.  The last thing they needed was more mouths to feed.

In 1968, there were 3.5 billion people, twenty years later 5.3 billion.  Paul and Anne Ehrlich realized that The Population Bomb had failed to inspire miraculous change, so they wrote The Population Explosion (1990).  The problems they had predicted earlier were now appearing in many places, and a new generation needed an excellent primer on overpopulation and its side effects.  This second book did not repeat the 1968 error of predicting timeframes.  It was much more substantial than the first, and is still illuminating to read today.  Readers will recognize that the raging bloody chaos of the twenty-first century is an obvious consequence of soaring overshoot.

In this second act, the Ehrlichs took readers into the ecological equivalent of an amusement park funhouse, where loud and scary ghouls and goblins frighten us at every turn — except that their eco-spooks were genuinely dangerous.  The trends in food production and population were not in any way encouraging.  In 1970, population was growing by 75 million per year.  By 1990, it was 95 million.

At the same time, staggering amounts of irreplaceable topsoil were being lost, aquifers were being depleted, and fields were being taken out of production because of salinization and waterlogging.  The Green Revolution surge in food production was peaking, whilst population continued to soar, setting the stage for crisis.  “We shouldn’t delude ourselves: the population explosion will come to an end before very long.”

North America produced 75 percent of the world’s grain exports, and the U.S. was the number one exporter.  In 1988, a severe drought reduced U.S. grain production from 300 to 200 million tons.  That year, Americans consumed more than they produced.  A stable climate was essential for crop production.  So was healthy topsoil, which was being lost at an estimated 24 to 26 billion tons per year.  So was cheap and abundant oil, and water for irrigation.

In 1990, the Ehrlichs were aware that global warming might become a serious problem some day, one that might disrupt agriculture, and spark major famines.  They knew that fossil energy was finite, and that we would be insane to burn it all.  But peak oil and climate change were not presented as current threats in this book.  The inevitable return to muscle-powered agriculture is certain take a huge bite out of food production, and an unstable climate will ensure unstable harvests.

Most of humankind lives in the northern hemisphere, in regions having a temperate climate.  These regions are where most of the world’s grain is produced.  Tropical regions are far more troublesome to farm, and they are home to most of the world’s hungry folks.  There is no winter to provide pest control.  Forest soils are typically thin.  Rains are often heavy, sweeping away soil, fertilizer, and pesticides.  The magic seeds of the Green Revolution do not thrive in the humid tropics.

A fascinating chapter reveals why it is so hard for us to take action on long-term issues.  It’s almost impossible to see, hear, touch, or smell greenhouse gasses, overpopulation, acid rain, aquifer depletion, soil destruction, or mass extinction.  These are not sudden, attention-grabbing events, like a charging rhino.  They are slow motion processes that are mostly perceptible via charts, graphs, and books.  We are tropical primates, and we evolved to pay close attention to the here and now, in the immediate vicinity.

Slow motion threats cannot be chased away with complaints or magical thinking.  We can’t seem to get interested in making enormous sacrifices today in the hope of theoretical benefits somewhere down the road, maybe.  Exponential growth can blindside us, because it’s slow at first, and gradually spins into a devastating whirlwind.  Evolution did not prepare us for civilized living.

The Ehrlichs are more homocentric than ecocentric.  Here’s a real boner: “The population problem is rooted in one of humanity’s greatest triumphs — overcoming natural controls on population size: predators, starvation, and disease.”  Triumphs?  Overcoming natural controls was the blunder that hurled us onto the path of doom!  Replace “triumphs” with “mistakes” and the line makes sense.  Natural controls work beautifully.  There are not 7.2 billion chimps staring at cell phones.

From 1968 to today, the main goal of the Ehrlichs has been to prevent the collapse of our global civilization.  In The Population Explosion, they fire hose readers with torrents of grim information.  Readers are likely to conclude that today’s global civilization is already far beyond the point of no return.  The solutions recommended require countless miracles, by next year, if possible — world leaders fully cooperating to rapidly reverse the course of humankind.

In a 2014 essay, they concluded that the odds of preventing collapse are now less than one percent.  Every civilization collapses, and not one has ever been anything close to sustainable.  Instead of rescuing civilization, wouldn’t a wiser goal be to quit destroying the ecosystem?  The early civilizations destroyed themselves by overexploiting renewable resources, like water, forests, and topsoil.  The newer ones are also extracting nonrenewable resources at an exponential rate.  We’re beating the stuffing out of the planet.

Sadly, the super-loony consumer lifestyle has been successfully marketed as being extremely cool.  Everyone in China, India, Africa, and everywhere else is eager to live as wastefully as possible, like Americans, but finite resources make this impossible.  Instead, Americans need to learn how to live like the people who pick their coffee beans, and we will, sooner or later.

Civilization appears to be speeding toward decades of collapses, yet most of us have little understanding of how we created our mob of predicaments.  Methinks it would be ideal to understand our boo-boos before the lights go out.  It would be great to quit repeating them.  Long ago, the introduction of plows increased carrying capacity.  Today, their continued use is reducing carrying capacity.  It’s important to understand this.

Here’s an essential sentence:  “The complacency with which our education system at all levels accepts the production of citizens hopelessly unequipped to understand the population explosion and many other aspects of the modern world is a national disgrace.”

The Population Bomb


In 1968, biologist Paul Ehrlich achieved infamy by publishing The Population Bomb, one of the most controversial eco-books ever printed.  Ehrlich has been condemned to spend eternity with Thomas Malthus, in a dungeon reserved for doom perverts.  To this day, professors still use the two lads as great reasons to never take seriously anyone who asserts that there are limits to growth.  We all know, of course, that humankind has no limits.  We have technology!

Actually, Malthus never predicted catastrophic famine.  He simply stated the obvious — when population reaches overshoot, the death rate will automatically rise to restore balance, one way or another (starvation, disease, conflict).  A thousand people cannot prosper if forced to share ten cheeseburgers a day.  The overshoot ceiling rises when food is abundant, and falls when food is scarce.  Malthus was not a doomer.  His cardinal sin was declaring the obvious — that there are limits to growth.

Ehrlich, on the other hand, actually did predict catastrophic famine, and soon.  The first lines in his book are, “The battle to feed all of humanity is over.  In the 1970s and 1980s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now.”  Millions indeed starved, but not hundreds of millions.  Everyone agrees that this prediction was inaccurate or premature.

When Ehrlich was writing, India was sliding toward catastrophic famine.  Only ten nations produced more food than they consumed in 1966.  In America, the postwar baby boom led to a freakish population spike of 55 million in 20 years.  The streets of 1968 were jammed with scruffy rebels protesting the Vietnam War, and our totally unhip way of life.  It was hip to be loud, brash, and vigorously opposed to the status quo.

At the same time, the Green Revolution was just getting rolling, and no one could foresee how well it would succeed at temporarily boosting grain production.  Norman Borlaug was the wizard of the Green Revolution, and his holy mission was to reduce world hunger.  He hoped that the new technology would give us 10 or 20 years to resolve our population issues.  We didn’t even try.  Those who recommend strict population control measures are called callous.  But the leaders who irresponsibly blew off an amazing opportunity were also callous.

Naturally, much more food led to many more people.  In 1968, there were 3.5 billion people, by late this morning there were 7.2 billion.  World hunger sharply increased, and many other problems worsened.  The Green Revolution had wonderful intentions, but its unintended consequences far exceeded its benefits, because we refused to seize the opportunity to confront and subdue the 800-pound gorilla.

The bottom line here is that Ehrlich’s predictions of catastrophe within a specific timeframe were wrong, but he succeeded in bringing a lot of attention to real and growing problems — population, pollution, and environmental destruction.  At the same time, he succeeded at pissing off almost everyone. 

Liberals hated him because he wanted to set population goals for poor nations, and withhold food aid for those who did not meet their goals.  He contemplated the notion of withholding food aid to nations that had zero chance of becoming self-sufficient.  He did not endorse the “right” of families to breed as they pleased — a right that was not handcuffed to responsibilities.

Religious people hated him because he believed that contraception and abortion should be legal everywhere, and that all children should receive rigorous training in sex education and family planning.  They hated him because he believed that fetuses were nothing more than potential humans.

Environmentalists hated him, because he was a lightning rod for criticism.  They believe that his fondness for bold statements made it hard for folks to trust anything that greens said.  He was a popular scapegoat to blame their failures on.  If Ehrlich had never been born, would we be living in a sustainable utopia today?

Conservatives hated him because he wanted to regulate pollution and pesticide use.  He advocated compulsory population control, because voluntary family planning has never been successful at stabilizing or reducing population.  Ehrlich detested their insane obsession with perpetual economic growth, which thrived on population growth, and disregarded ecocide.  But they loved him for being so loud and so bizarre.  He made it easy for them to label all greens as hysterical nutjobs.

Modern society is suffocating in information.  Everyone in a hunter-gatherer clan knew the entire collection of their cultural information.  Today, we don’t know a millionth of our cultural information, because knowing it all is impossible.  So, climatologists are freaked out about rising temperatures, while the masses are blissfully ignorant.  Petroleum geologists are freaked out about the looming specter of Peak Energy, while the masses are not.

Within the realm of his specialty, Ehrlich could perceive enormous threats that society was unaware of, and this freaked him out.  He was compelled to rattle cages.  If he had written a dry, mature, scholarly discourse on population, with 300 footnotes, it would not have reached a general audience and provoked lively and widespread discussion.  In modern society, suffocating in information, you get attention by flaming and screaming, like the election ads for candidates.  Whether or not it is honorable, it works.  In my opinion, Ehrlich’s opinions were sincere, and a bit inflamed, but not devious fabrications.

Ehrlich’s book was read by many, and it drew needed attention to a crucial issue.  A taboo subject was let out of the closet, for a while.  Others were inspired to write books.  Green organizations boldly called for action, but many checkbook activists promptly revolted by putting away their checkbooks.  So, the issue of overpopulation was handed over to Big Mama Nature to resolve, and she will.

While his ideas continue to outrage many, they do have a basis in cold, hard reason.  We could reward couples who don’t marry until 25, and those who space their children at least five years apart.  Childfree people could be eligible to win lottery prizes.  “There has been little effective criticism of the medical profession or the government for their preoccupation with death control… death control in the absence of birth control is self-defeating.”

It would have been cool if humans were purely rational, realized their mistake, and took bold action to divert disaster.  Ehrlich sighed.  “By now you are probably fed up with this discussion.  Americans will do none of these things, you say.  Well, I’m inclined to agree.”  He wrote because there was a wee chance for success.

Don’t read this book to learn about overpopulation and its side effects.  Hundreds of newer books are far more up to date.  Read this book to contemplate morals, ethics, taboos, ideologies, and communication.  Contemplate his critics, and why they are so determined to banish discussion on an issue that is a major threat to humankind and the planet (see the reader comments on Amazon.com).  The anger and pain that continues to swirl around this book provides a fascinating study in human nature — long-term survival vs. a mentally unstable culture. 

Ehrlich is an intelligent and charismatic fellow.  In 2008, on the fortieth anniversary of The Population Bomb, he reread his book and blushed a bit.  He had learned a few new things in the preceding forty years, but his overall impression was that in 1968 he had been far too optimistic.  He presented his current perspective in a lecture at Stanford, From the Population Bomb to the Dominant Animal (54 min.).

The Ostrich Factor


Garrett Hardin was a lad who not only thought a lot, but could also think well.  I recently discovered a Hardin book I had not heard of, The Ostrich Factor — Our Population Myopia (1998).  Hardin was an interesting blend of an ecological conservative, and a growth-hating political conservative who detested economists.  I hoped that this book would provide fresh insights on the huge and difficult problem of overpopulation.

After Living Within Limits was published in 1993, critics noted that Hardin complained about overpopulation, but failed to provide a remedy.  Hardin admitted that he had been intimidated by the explosive taboo on the subject, which incinerates every dreamer who blunders into it, foolishly preaching common sense.  Hence, the ostrich factor — never touch 800-volt issues that are surrounded by large piles of scorched skeletons.  You can’t win, so bury your head in the sand, and have a nice day!

There is a widespread fantasy, drilled into us by cultural myths, that our society is guided by reason and elevated moral principles.  It’s silly nonsense, but we have a hard time seeing this.  Many people waste their entire lives, sad victims of the tragedy of the consumers — powerful myths that compel us to spend our lives working, in order to move as much stuff as possible from nature to landfills, in order to gain the respect of our peer group, which suffers from the same mass hysteria.  Well-trained consumers never question 800-volt myths.

Modern society is focused on the individual, not the community or ecosystem.  I am all that matters.  If I can gain status and respect by wiping out forests or fisheries, or throwing the planet’s climate out of balance, I will.  I don’t care that I’m leaving behind a wasteland for future generations.  Of course, if future generations were able to vote today, or if we were raised in a sane culture, our world would be radically different and far healthier.

Hardin was fascinated by the poisonous power of taboos, and he invited an imaginary Martian into his book, to observe our society as an objective outsider.  (I wish he had used humans from the future.)  The two of them explored uncomfortable notions that will make some readers squirm and snarl.  They provide us with intense lessons about the powerful headlock that taboos have on our ability to think.  Taboos push many commonsense ideas off limits, severely handicapping our freedom to think, forcing many to live like two-year olds, ecological psychopaths, or chronically depressed shoppers.

Taboos vary from place to place and time to time.  I was surprised to see that Hardin only mentioned abortion once, with regard to a quote from 1886, describing a situation where abortion was legal, but contraception was not.  In that scenario, many physicians chose to break the law against providing contraception.

It is important to understand that many wild cultures had customs that encouraged population stability.  Their ongoing survival depended entirely on food from the surrounding wild ecosystem, and too many mouths led to painful problems.  Their utmost concern was the health and stability of the community, not the whims of individuals.  They shared and cooperated.  It was obvious to them that the carrying capacity of their ecosystem had genuine limits.  For us, living in a temporary wonderland of supermarkets, limits are hard to imagine — until we crash into them.

The emergence of agriculture redefined carrying capacity, which varied from year to year, depending on the harvest.  Limits on breeding weakened or vanished.  Hardin quoted Tertullian, a third century Christian thinker from Tunisia, who was spooked by the misery of overpopulation (when the global population was 150 million).

Tertullian wrote, “As our demands grow greater, our complaints against nature’s inadequacy are heard by all.  The scourges of pestilence, famine, wars, and earthquakes have come to be regarded as a blessing to overcrowded nations, since they serve to prune away the luxuriant growth of the human race.”

Like Tertullian, Reverend Malthus (1766-1834) also lived in an era of turbulent growth, and he became a notorious heretic for reminding society about the existence of carrying capacity.  Two hundred years later, he remains fiercely detested, mostly by people who have never read him, because he pointed out a serious 800-volt issue, a super-taboo.  Never, never, never suggest that there are limits to growth!

Perpetual growth on a finite planet is obviously impossible, obviously insane, and insanely destructive.  Sustainable growth is an oxymoron.  But few goofy myths are more powerful.  We are constantly reminded that perpetual growth is the purpose of life.  Grow or die!  Our official religion is Growth Forever.  Fanatical believers are called optimistic, and optimism is “good.”  Hardin disagreed, “At the present rate of population growth, it’s difficult to be optimistic about the future.”

With regard to population, our culture asserts two rights simultaneously.  (1) Right to life.  The UN decrees that “every man, woman, and child has the inalienable right to be free from hunger and malnutrition.”  (2) Right to limitless reproductive freedom.  “Every woman has the right — perhaps with the agreement of her mate(s) — to determine how many children she shall produce.”

There are no natural rights; rights are legal inventions.  Note that these two sacred rights are not accompanied by sacred responsibilities.  Hardin concluded that overpopulation would not be resolved by the voluntary choices of individual families.  In a finite world, unrestricted freedom is intolerable.  Survival is mandatory; freedom is not.  Effective solutions should be based on community-sensitive rules, ideally produced by a policy of “mutual coercion, mutually agreed upon.”  Our wild ancestors generally succeeded in doing this, because their cultures saw limits as being perfectly normal, not draconian.

Hardin knew that “coercion” is an obscene word in a culture that worships individualism, but he noted that we submit to coercion when we stop for red lights, or when we bike on the right side of the road.  Coercion is often reciprocal.  Money is coercion.  There are many things we will eagerly do for money that we would never do for free.  We are often coerced by nothing more than a sweet “pretty please.”

Hardin thought that one world government was impossible, because there is not a single world culture.  Trying to get different cultures to agree on anything is a challenge for advocates of multiculturalism.  Because of this, Hardin offered no silver bullet solution for the world.  Each culture will have to design its own method for limiting population.

Predicaments have no solutions, but problems do.  Overpopulation is merely a temporary problem, and there are two solutions.  (1) We can make a commonsense effort to live below carrying capacity.  (2) We can bury our heads in the sand, make no effort to influence the future, and let Big Mama Nature mercilessly do the dirty work.  The commonsense approach saves a lot of wear and tear on the ecosystem, and makes life far less hellish.  It is enthusiastically endorsed by the spirits of future generations.

Living Within Limits


Garrett Hardin (1915-2003) was famous for an essay, The Tragedy of the Commons, written in 1968.  He thought that folks who kept their cattle on common lands had little concern for the condition of the pasture, while private pastures befitted from the careful stewardship of wise ranchers.  In 1998, in response to critics, he published The Tragedy of the Commons — Extension, in which admitted that a better title for his essay would have been The Tragedy of the Unmanaged Commons.

I was unsure of his message.  Everyone understands that privately owned cropland is degraded with every pass of the plow, year after year, despite being managed by government rules and regulations.  Private land is often permanently ruined by mining and manufacturing enterprises.  Maybe the root of the tragedy was our civilized mindset — nature was created for human use, and the future doesn’t matter.

For years, I dismissed Hardin as a free enterprise gadfly.  I discovered I was wrong when I read Living Within Limits.  He was an enthusiastic critic of economic growth and population growth.  In this book, Hardin had a heroic goal — radically reforming industrial civilization before it disintegrated.  He read mountains of books, and generated an enormous stream of rational ideas and recommendations.

He plowed through multiple editions of Malthus, and concluded that the good Reverend was 95 percent right, which delighted me.  Hardin summarized the message of Malthus as, “Disaster is a natural outcome of perpetual population growth, but disaster can be forestalled if society can find the will to put an end to population growth.”  Poor Malthus has been widely hated for 200 years, most commonly by those who have never read him.  His great sin was in questioning the trendy belief that civilization was in the fast lane to utopia, where humankind would achieve flawless perfection.

Hardin learned that enlightening the befuddled world was a frustrating endeavor.  Questioning sacred norms instantly turned you into a dangerous nutjob.  Alas, the modern world was as rational as a loony bin — despite the fact that we were the most highly educated generation that ever walked the Earth.  The notion that there were limits was impossible to accept.  He believed that the only thing that’s truly limitless is debt.

Here we are, well into the twenty-first century, still pissing away billions of dollars in the ridiculous pursuit of colonizing other planets.  We need more space to grow, more resources to mine, fresh ecosystems to destroy.  Would you volunteer for a 400-year voyage in a small metal capsule?

Here we are, still feverishly determined to pursue economic growth by any means necessary.  Almost all economists suffer from the hallucination that endless economic growth is possible and desirable; resources are infinite.  The sun is setting on the cheap energy bubble, which will eventually bring growth to a halt, and shift it into reverse.  Well, let’s not think about that.

Here we are, several years beyond the peak of the global production of conventional oil, paying no attention to the foreseeable challenges ahead — production will continuously decline, whilst prices will continuously rise.  M. King Hubbert, a Shell Oil geologist, predicted this in 1948, and the crowd chuckled.  Hardin included a stunning graph that charts annual energy use, from 5,000 years past, to 5,000 years forward.  At the center of this 10,000 year timeline appears one icicle-shaped spike, lasting a few hundred years, then dropping back to normal (a chart of population would look about the same).  Of all the oil we will ever consume, 80 percent of it will have been extracted during a 56-year binge, roughly from 1969 to 2025.  Let’s not think about that.

Here we are, still refusing to seriously consider the huge problem of overpopulation.  Our boundless optimism has no doubt that miraculous technology will solve any problem.  For almost the entire hominid journey, the rate of population growth has been close to zero.  The rate rose a bit when ancestors got interested in tools, it rose more with the advent of agriculture, and it skyrocketed during the fossil fuel disaster — a reality that we consider to be normal.  Hardin imagined that we will be happier when the herd shrinks to a half billion or so, as it was in 1492.

The problem is that, one by one, we’ve eliminated many of the controls that used to keep our population in balance.  We killed off most man-eating predators.  We developed a food production system that reduces the risk of famine.  We built sanitation systems to prevent pandemics of fecal-oral diseases.  We invented vaccinations and antibiotics to cure or prevent contagious diseases. 

The remaining birth control options are voluntary, and Hardin insisted that voluntary efforts have always failed in the long run.  An effective solution can only be based on coercion.  We’re coerced to stop for red lights, aren’t we?  Talking about reproductive rights without equal regard for reproductive responsibilities is foolish.  Why hasn’t Congress fixed this problem already?

Hardin also detested immigration.  America is a high waste society, and it’s highly overpopulated.  Is it truly our obligation to care for everyone?  There are two billion poor folks in the world.  Shall we invite them all to join us?  Or, should we send them lots of food? 

Overpopulated poor countries are living beyond their carrying capacity, and this cannot not fixed by sending them food.  More food reliably results in even more hungry people.  Hardin thought this was dumb — we should simply mind our own business, let nature take its course, and allow balance to be restored.  He thought that the leaders of poor countries had an obligation to take responsibility for their overpopulation, and develop appropriate solutions.  It’s their job.

It’s been 20 years since Hardin’s book was published, and everything has rapidly gotten worse.  There is clearly a sense of frustration and despair in his words.  We’re heading for a bloody disaster, and nobody cares!  The problems are obvious, as are intelligent responses.  (Scream!) 

I used to feel that pain.  The pain was rooted in the expectation that modern society should behave in a rational manner, as we were taught in school.  I’ve since realized that this expectation was absurd and harmful.  We are who we are, and we’ll change when we run out of options.  The pain has faded. 

In theory, humankind is not fatally flawed.  Almost all of our ancestors lived in a relatively sustainable manner.  They developed voluntary methods of birth control that worked quite well.  Genetically, we are purebred hunter-gatherers, beautifully evolved for a low-impact life in the great outdoors.  Our experiment with civilization has been purely unnatural.  Our current problems emerged in the last few thousand years.  In theory, we can learn from our mistakes, and return to living in balance.  In the long run, it’s either balance or bye-bye.

By definition, an unsustainable population can only be temporary.  The same is true for continuous economic growth.  Time will fix these mistakes, with or without our assistance.  We should have listened to Hardin, but we didn’t, so we’ll leave more scars on the planet.  The scar of an unbalanced climate may not heal for a long, long time.  It’s quite possible that warming will force the human journey into a new and very different direction.  Should we think about it?
