Extinction of Man

“At this point 29 percent of fish and seafood species have collapsed — that
is, their catch has declined by 90 percent. It is a very clear trend, and it is
accelerating. If the long-term trend continues, all fish and seafood species are projected to collapse within my
lifetime — by 2048.”

Introduction
This is not a particularly cheerful essay. It is about the probability of man’s long term survival. Just how much
longer will man be around on planet earth? Man is a relative newcomer to the planet, but gives all signs he will be a
bust, and will soon be gone.
Our Heritage
Reading about our ancestors, you have to marvel at how they persisted through extreme hardships. Man is a adaptable
animal that managed to survive from the arctic to the equator, in deserts and on the oceans. We have even survived ice
ages.
We lived in small groups where everyone knew each other, and where your loyalty was to the group. There was no need ever
to plan more than a year ahead.
Yet, even before we invented technology, we stripped the forests of Greece bare and denuded her soils. The fabled Cedars
of Lebanon were gone long before the chainsaw was invented.
Our Predicament
Mankind faces a series of unprecedented threats. He is not capable of dealing with them because they overwhelm his here
and now focus. They require thinking of the world as a whole. They require considering the effects on generations to
come, not just the next quarter bottom line. I will consider only four of dozens of major problems threatening mankind:
oil depletion, germ warfare, global warming and nuclear war.
Oil Depletion
Mankind today depends on technology and oil for the green revolution to feed her teeming billions. Oil is used to make
fertilizers, pesticides and fuels for farm machinery and food processing. Without that, the population of the earth will
have collapse back to under a billion — what it was before these things were invented. According to Scientific
American, by 2020 the flow of oil will have reduced to half what it was in 2000.
The price will far more than double, effectively cutting off the poorer half of the world from having any. There is hope
some new technology will help fill the oil-gap, but so far it is just a trickle. However disruptive oil depletion may be,
it is not extinction.
Germ Warfare
Mankind has discovered how to create life, molecule by molecule. Even an undergraduate geneticist can cook up a new form
of AIDS or polio. The very first thing man did with this new found knowledge was to create super bugs for germ warfare —
e.g. innoculation-resistant smallpox. If these pathogens are ever let loose in error, by terrorists or by armies, they
may kill billions, but that is still not extinction. However, as understanding of human physiology increases, it is only
a matter of time until we learn to create pathogens completely lethal to everyone. That is extinction. Humans,
genetically, are almost clones. We are much more susceptible than other species to this sort of attack.
The USA and Russia foolishly did the research to make it easy for every two-bit terrorist to destroy city.
Global Warming
Mankind is embarking on a strange ecological experiment. Over a couple of centuries, man is burning the carbon
accumulated over millions of years by plants. The CO2 levels are now at the
level of the Permian extinction. There have been two mass extinctions in earth history, the Permian, 230 million years
ago, was the worst. 70% of all species were lost. It was caused by natural global warming
when volcanoes released greenhouse gases. (The other more familiar to most people was the more recent KT Cretaceous-Tertiary
Mass Extinction event, 65 million years ago. It was caused when an asteroid plunged into the earth at Chicxulub Mexico
wiping out the dinosaurs and half of earth’s species.) We are re-experiencing the same global warming conditions
that triggered the more devastating Permian extinction, only this time it is man made. When it gets too hot, plants die.
When it gets too hot and dry, massive fires ravage huge areas. When plants die, insects and herbivores die. When insects
die, even heat-resistant plant’s don’t get pollinated and die. Birds die without insects to eat. Carnivores
die without herbivores to eat, all triggered by what seems so innocuous — heat. Similarly, in the oceans, when
they get just a few degrees too warm, corals expel their symbiotic algae and die soon thereafter. When coral reefs die,
the fish that live on them die, triggering extinction chains. Satellites can chart the loss of vegetation over the
planet. We are losing 4 species per hour, a rate on the same scale as the Permian and KT extinction events. Man has no
ability to live without the support of other species. We are committing suicide and killing the family of life on earth
along with us. The question is, will we wipe ourselves out along with the rest of the planet’s ecology? Man is
very adaptable. He will destroy his food supply on land and in the oceans as a result, but some people will survive.
That is not complete extinction.
Nuclear War
Mankind has discovered how to harness the atom. The first thing he did with that knowledge was vaporize two Japanese
cities. Now he has stockpiles of weapons capable of killing everyone on earth many times over. Extinction becomes a
distinct possibility. All it takes in one person in the next 500 years with access to trigger a
war, and it is all over. Perhaps a handful of humans might survive in some remote Amazon jungle, but man will have put
himself back to the stone age level of culture. Everything we have achieved will be lost.
John Kennedy estimated that the odds were between one in three, and one in two, that he would start a nuclear war during
the Cuban Missile Crisis. Except on Star Trek, you can’t repeatedly do things that dangerous and live to tell
about them. The odds eventually catch up with you.
Even after nuclear war, some life will survive. We humans may all die, but some species would survive, and evolution
would continue its slow pace, eventually bringing a new crop of creatures to earth.
Nanites
“To err is human, but to really foul things up requires a computer.”
~ Farmer’s Almanac
, 1978
This may sound like science fiction, but in the not too distant future we will be creating microscopic robots called nanites
by the bucketful. Eventually we will create self-replicating nanites, ones that build more copies of themselves all on
their own. It is not hard too imagine a runaway overpopulation process, much like Mickey Mouse in the Sorcerer’s
Apprentice. If anybody ever slips up in “birth control” for these critters they could bury us all alive in
great grey goo as they turned everything on the surface of the planet into still more nanites.
This is not my private paranoid fantasy. It is shared by distinguished futurists such as Raymond
Kurzweil.
Lesser Assaults
“If
builders built buildings the way programmers write programs, then the first woodpecker that came along would destroy
civilization.”
~ Weinberg’s Second Law
(born: 1933 age: 76)
Technological societies are so finely tuned that they can collapse at the tiniest provocation. There are only three days
worth of food in the supermarkets. Terrorists can blow up high voltage transmission lines, subways or freeways. A single
accident on the Mississippi river fouled up gasoline production in the USA for a month.
Modern farming exposes the soil to erosion. We have lost more soil in the last century than took hundreds of thousands
of years to build up. You can’t grow crops without soil. Every year Kansas loses 2 to 8 tons of soil per acre of
farmland. Yet, we refuse to address the problem.
Global warming will cause a dust bowl in the corn belt of the USA, ending its agricultural abundance.
Corporate Capitalism
Man is naturally greedy and short-sighted, but the invention of corporate capitalism (as compared with free-market
capitalism) has magnified that tendency. We have created powerful institutions who bribe government officials to do
things that help the short term profit of companies, but which hurt the health, safety of citizens and long term profit
of corporations.
Corporations are pseudo people with psychotic personalities, required by law to be devoid of conscience. They are not
permitted to be concerned with the interest of the stakeholders: the employees, the customers, the people living where
the corporation does business. By law they must consider only profit for the shareholders.
They will do things like bribe the government to allow them to dump pollutants such as pig manure into the water, then
fob the cost of cleaning them up on the public, rather than building them into the cost of the product, the way you
would in a true free-market economy. Lack of care of the soil is good for short term profit, but soil loss is disastrous
for the crops of future generations.
The problem is, these corporations are actively working as hard as they can against the public interest. For example.
- They are trying to increase oil consumption.
- They are trying to increase research into ever more lethal germ warfare.
- They are trying to increase the amount of greenhouse gasses released into the air.
- They are trying to increase the sales of nuclear weapons and home and abroad.
- They are trying to discourage space exploration in favour of military spending where there is no clear deliverable.
Even without these corporate enemies of planet earth, our planet has little chance of success. Yet their power grows
daily through phony free trade agreements like NAFTA and WTO.
Jehovism
In the Jehovist (extended Judeo-Christian) family of religions I include, Judaism, Christianity, Islam, Mormonism,
Christian Science and Jehovah’s Witnesses. I might exclude the Quakers. The Jehovists are weak in preserving life
on planet earth. This anti-life, anti-earth attitude has several roots:
- In Genesis is the source of the belief that man is a special animal with dominion over all other species to do with as
he pleases. Jehovists are so vain as to imagine the creator of the universe prefers habitually take the shape of a
primate on an obscure planet in a remote corner of the Milky Way, named Homo Sapiens. They pretend not to notice the
other intelligent more peaceful species on earth, the elephants, dolphins and whales.
- The emphasis on the unimportance of the physical world as unreal, just a test for the afterlife, a temporary world until
Christ returns, a source of temptation from the spiritual life and the domain of Satan.
- Jehovists distinguish themselves from other religions that honour the earth, trees, rivers etc. Jehovists are proud of
the fact they do not honour the environment. They consider that sacrilegious.
- The precise rules for various mandatory blood animal sacrifices consume most of Leviticus.
- The stance that non-believers are inferior beings whose life has no value. Even people in slightly variant sects treat
each other as enemies.
- Jehovah himself is depicted as violent, bloodthirsty, arbitrary and unjust.
How can you expect his followers to behave any better?
In contrast, the Jains and Buddhists foster a reverence for all life. They are supposed to avoid hurting even insects.
So what does this have to do with extinction? As science creates more and more ways for even one man to wipe out the
entire planet, you need extreme taboos to stop people from doing that. Jehovists don’t have anywhere near
enough inhibition. From my point of view, they are like Vikings who have accepted violence and destruction as perfectly
normal. They don’t even notice what they are doing. Everywhere they have spread they have stripped the planet bare,
polluted its waters, overpopulated, made war, enslaved others, exuded greenhouse gasses with abandon, squandered the
resources of earth in conspicuous consumption, exteriminated species after species and generally behaved like the
proverbial savages they claim everyone else to be. They are far too vengeful to be entrusted with dangerous tools like
the atom and biotechnology. Too bad. They already have them. The most powerful man on earth, George W. Bush is a
fundamentalist Jehovist whacko who imagines the voices in his head telling him to butcher and torture, are God himself.
Do We Deserve To Live?
Mankind is like a monkey. He is clever but not wise. It is only a matter of time until he kills himself with his
cleverness and lack of caution.
Man has little concern for other species on the ecological health of the planet as a whole. He ignores natural limits,
simply because they are inconvenient. He imagines his economic activity can grow without limit, he can burn oil without
limit, he can pollute without limit, he can extract resources from the earth without limit.
He is fiercely loyal to his country, his company, his team, his tribe, his family, no matter what evil things they have
done.
Only a tiny fraction of the planet’s inhabitants see themselves as citizens of planet earth first, and of some
particular country second. Only a tiny fraction of the planet’s inhabitants care about people outside their
immediate families. Only a handful of the planet’s inhabitants think deeply about the effect they will have on
generations to come. It seem unlikely these altruistic survival traits will spread in time. Hanging on tenaciously to
the outmoded us-vs-them mentality and short-term greed seals our doom. We deserve to die.
It may be a good thing man blows himself up before he develops the technology to destroy an entire galaxy.
The Escape
Once man has colonised several planets, one planet could go up in a nuclear conflagration without destroying the rest.
The survivors would be stonily shocked into giving up such foolish weapons. Until that point, if earth goes, man goes.
Unfortunately, exploration of space has taken a back seat to military exploitation of resource-rich third world nations.
The other escape would be nuclear disarmament. Man is too stupid. He would rather see everyone die than his neighbour
potentially take advantage of him. The USA wants its nukes not for defence, but to intimidate and bully the nations of
the earth to bolster its economic exploitation. It won’t give up that privileged position.
Rays of Hope
“Never doubt that a small group of thoughtful committed citizens can change the world; indeed it is the only thing
that ever has.”
~ Margaret Mead (born: 1901-12-16 died: 1978-11-15 at age: 76)
Young people are much clearer about man’s fragility than their elders. If we are lucky, the old farts like George
W. Bush will die off from cholesterol poisoning before they have totally destroyed the planet.
Computers with the memory capacity and computing capacity of the human brain are due about 2020.
They will do some things amazingly better than humans, just as now. Most likely, they will run circles around us in
logical thinking. If we are very lucky, they may be very good at simulating the effects of various policies, and will be
able to explain with 3D graphics exactly what the effects of the politicians’ actions will be. If they are
sufficiently good salesmen, they may save earth. In the process though, we will have become obsolete ourselves.
I have one other thread of hope. Back in 1969, I was the only person on earth I knew of who
felt that gays should be treated with respect. Even my fellow gays seemed to think they deserved contempt. I started my
little gay lib project knowing it was completely futile. I thought, even if I did seven lectures a week and managed to
change everyone’s mind in the audience, it would make only a tiny dent. Yet within three years we had the first
gay rights legislation in British Columbia. Perhaps it was not just a co-incidence. I discuss this in my essay on quantum
miracles. It may be your personal choice whether you live in a world where man goes extinct or in one where he
prevails.
Overwhelm
The natural reaction of someone reading this essay is to go into overwhelm. This is just too much bad news to digest at
once. People have their own various techniques for dealing with it. The most common is denial. Gloom and doom must
automatically be false. Folks will happily ignore the hard facts of global warming, soil erosion and aquifer depletion,
and glom onto any unscientific crackpot like Bjørn Lomborg or George Bush so long as he paints a rosy picture.
Some will comfort themselves with wishful thinking. “God won’t let things get that bad.” totally
forgetting God has been quite happy to permit even worse suffering in past. Some will simply put these issues out of
mind.
The problem is this denial makes the problems worse. Not only to people fail to take action, they actively interfere
with others taking action. So to be optimally effective, you must upset and worry.
Summary
It seems unlikely man will survive the next hundred years. The question then becomes, how many other species will man
take down with him. Will the dolphins, elephants and whales have to die too?
Does this mean you should just give up and die right now? No. Butterflies and roses live only a day, yet they have value
in the moment. If you were on a sports team playing a much stronger team. Would you give up just because the odds were
against you? Of course not. Here the stakes are much higher than any sporting event, namely the survival of our species
and most of the other species of our planet.
