Catastrophic
Events:
A Catastrophic Event, as defined by The Future Watch, is an
event which, at a minimum, causes the fall of modern civilization. This
page is intended to provide a comprehensive list of all plausible events of this
nature. If we have not listed one such event, please feel free to contact
us at admin@thefuturewatch.com to rectify the
situation. Eventually we would like to link each event to its own page
which would analyze the event in detail. If anyone has any particular
knowledge regarding a possible catastrophic event, and would like to contribute
to the page, please feel free to submit to us an analysis of the event, its
magnitude, its likelihood, and ways of preventing or mitigating it. We
will of course give full credit to any author whose analysis is used on the
site. Please include documentation for any controversial statements of
fact.
Category: Suicide by Weapon
of Mass Destruction
Nuclear
Weapons: Nuclear weapons were
the first technology to be developed that allowed our species to render
itself extinct by choice. And, indeed, we quickly built (and yet retain)
enough of these weapons to do so. That said, we survived the Cold War, and
the political climate between the major powers has improved. Furthermore,
the fact we survived the brinkmanship of the Cold War suggests that the leaders
of major nuclear powers can be trusted to behave responsibly with their
arsenals. It isn't easy to become a leader of a major power. Someone
who does so has normally had to survive years or decades of infighting.
Such a person normally is ambitious, smart, rational, and power-hungry enough
that they won't choose to sacrifice their ideals, their countries, and their
lives, in a haze of mushroom clouds. So, while a large scale
nuclear war is possible, and it could cause the end of civilization or of
our species, it isn't nearly as serious a threat as some of the others we
face.
Bioweapons: Bioweapons are the threat of tomorrow. Like nuclear weapons, the first truly
calamitous bioweapons will be (or have been) created and stored in secure
government-run facilities. Unfortunately, unlike nuclear
weapons,within the next three or four decades, incredibly infectious
lethal bioweapons will probably be available to anyone with a few million
dollars and a couple of well-trained scientists. The DOD (among others) is working on some interesting ideas for
protecting against bioweapons - including some vaccines that could be effective
against almost any virus. That said, advancements in bioweaponry still
seem far more certain than the advancements in biological defenses. If
bioweapons do become readily available to small numbers of individuals (as seems
likely), then one or two hate-filled ideologues could end our species. The authors of this
website believe this to be one of the most likely outcomes for 21st century
man.
Nanotech Weapons: Many optimists envision a
future in which self-replicating tiny machines are ubiquitous and perform a wide variety of tasks - from
building perfect objects molecule by molecule, to swarming in your
bloodstream and quickly repairing any damage to your body. So far,
however, it's been very difficult to build useful self-replicating nano-scale
machines. Quantum effects complicate the attempt, and the whole effort
could achieve little success. That said, there is a darker side to the
possibility of self-replicating nano-scale machines. Designed as
a weapon, these invisible machines could chew through organic flesh and leave
behind only millions of copies of themselves. Or, designed to do
a constructive task, these machines, if their constituent
elements were common, could replicate out of control and consume a significant
fraction of our planet - destroying our species in the process. That
said, while many futurists view nanotechnology as ultimately more dangerous than
bioweaponry, the danger is almost certainly several decades further
off.
Category: Suicide
by Accident
Global
Warming: Global
warming isn't likely to drive us extinct. That said, we can't adequately
predict how all of the world's feedback mechanisms will respond to an drastically increased amount of CO2 in the air and to a warmer
planet. One possible result of our experiment with the planet's atmosphere
is run-away temperature change (either warming or
cooling). Although we don't know for certain how much of a global
temperature change would be necessary to create an
ecological disaster, such a change certainly isn't out of the question.
Furthermore, a warming world will probably lead to increasingly violent weather
patterns and to substantial desertification. Any of these changes could
easily disrupt food supplies for much of the world, and thereby cause the
collapse of civilization. Furthermore, even if climate change doesn't
prove to be catastrophic, our increased CO2 levels are increasing the acidity of
the oceans. If the acidity level increases too much, it could have a
deadly effect on ocean life - which would in turn have
major repercussions on other ecosystems and on
our food supply.
Fuel Shortage:
Civilization today is dependent on abundant cheap sources of
energy. Without these supplies of energy, the world's economy would
collapse, and, more importantly, we wouldn't be able to grow and transport even
a fraction of the food the world's 6 billion plus people need to survive.
The most important source of energy right now is oil. Yet our supplies of
oil are limited, and many oil reserves are located in unstable parts of the
world. Policy-makers finally seem to have begun feeling the urgency for us
to develop alternative sources of energy. That said, if we face unforeseen
technical or political difficulties, and we fail to end our dependency on oil
before supplies of it run low, then civilization will face
collapse.
Economic Collapse:
The economic future of
the world looks bright right now. Europe, America, Japan, and several
other regions of the world have modern, industrialized economies which enable
their people to enjoy easy access to all of the necessities, in addition to good educations,
and many luxuries. China and India are both growing rapidly, and between
the two of them, they contain over 1/3 of the world's population. That
said, there is some uncertainty about the future of the world's economy.
America is deeply indebted to foreign lenders - perhaps dangerously so.
Both European and American governments have made large financial commitments to their people - commitments which are easy to grow and difficult to
shrink. These commitments could necessitate
burdensome taxes that stifle their economies.
Furthermore, advancements in technology may lead to a
future where machines replace workers in most professions - rendering almost
unemployable a large fraction of society. Large scale economic disruptions
have had cataclysmic effects in the past, and they may
again.
Massive Crop
Failure: There a number
of situations that could lead to widespread crop failure, some of which have
already been mentioned. There are a few other ways in which we could
imperil food supply, however. We could accidentally (or purposely) kill off an important
pollinating agent (bees, some birds). Or, we could continue
becoming increasingly reliant on one or two strains of a small number of plant
species - which are highly vulnerable to pests that are specialized to eat
that particular strain of plant. If crop failure, for any reason, is
sufficiently widespread and affects enough species, then the end of modern
civilization will be the result.
Suicide by Strangelet: This category could
more properly be termed "suicide by scientific experiment with possible
catastrophic effects." Generally speaking scientists are responsible,
reasonable, moral people. That said, their job is to conduct experiments,
and, very infrequently one of these experiments does contain a small potential
for disastrous results.
This situation can arise in every branch of science, but the
possibility of destruction can be particularly spectacular when it results from
a physics experiment. The new Relativistic Heavy Ion Collider at the Brookhaven National Laboratory smacks gold ions together at
nearly the speed of light. When it does so, for an incredibly short
period of time, the protons and neutrons in the ions are torn apart into a sort
of "quark soup." Physicists don't know all that much about
the behavior of this "soup," which is why they want to
experiment. Several unlikely scenarios have
been raised for how experiments of this nature could cause a catastrophe.
The most likely of these possibilities (the one that is still given the most
credence from the greatest number of physicists) is that a negatively charged
strangelet could be created. If this strangelet had a reasonably long half-life, it could potentially convert the
entire Earth into strange matter (destroying everything in the process).
Another particularly horrifying (although even more unlikely) possibility is
that our experiments inadvertently trigger a
transition to a lower vacuum state. In layman's terms this would mean the
end of everything in the universe (although the catastrophe would propagate at
the speed of life - so most of the universe would continue to exist long after
we were gone).
Suicide by Technological Advance:
The adoption of new technology
normally precedes complete knowledge of the repercussions of the technology. For example, we adopted
a new system of raising and feeding animals - only to discover that our system
helped spread a prion that decayed brains (including, apparently human
brains). Imagine if prions had spread far more rapidly and had less effect
on cattle and greater effect on humans - anyone who has eaten beef would be at
real risk of having their brain turn to sponge. Likewise, new evidence
continues to come to light that cell phones have a greater effect on the brain
than was previously thought. Will two or three decades of frequent use
from an early age lead to widespread health problems among our youngest
generation? In a similar vein, there is speculation that cell phones may
be the cause of our current bee shortage - a shortage that threatens a number of
crops. We are adopting new technologies every day - and any one of them
could have unforeseen effects. In the worst case
scenario, one of these surprises could threaten our
civilization.
Replacement:
We are rapidly developing faster computers and better
machines. If these advancements continue, machines will probably replace
humans in the workplace. This has already begun to happen with
unskilled workers, and it will eventually happen at all levels of the
workforce. Furthermore, advances in computer technology make it likely
that we will develop computers that are smarter than ourselves in every way -
and which are capable of completely emulating the thought processes of a human
brain. Once this occurs, we will have, in some
fundamental way, lost control of our machines. If they do not make good
decisions for us, we will be unable to effectively oppose them. We may be
unable to realistically predict what end this situation will lead to.
Category: Murder
Alien Attack: One possible explanation for the lack of evidence of
extra-terrestrial intelligent life is that technologically advanced species
exist, but they did not lose the violent edge to their competitive drive as they expanded into space. In such a
universe, the galaxy is a dangerous place, and technologically advanced species
remain hidden for fear of attracting unwanted attention. In this
scenario, an advanced intelligent species might reasonably conclude that it is
safer to eliminate potential competitors before they can become a threat.
We've happily obliged any species that wants to kill us
by providing a century's worth of radio signals, and, indeed, we've gone
further than that to proudly send out signals to the stars in an attempt to
contact other species. As a result, we may be awaiting the arrival of an
alien attack. Unlike the movies, this attack probably won't be something
we can fight against. A large mass accelerated up to relativistic speeds and aimed at the Earth would hit us almost
before we knew it was coming - and it could easily wipe out all life on our
planet. Advanced self-replicating machines could overwhelm our defenses,
and, in fact, consume our planet. Suffice to say, if an intelligent
species knows about us, and wants to kill us, it will probably be very easy for
it (so long as we are dependent on a single planet,
anyway).
The Wrath of God: There are actually two possible versions of this
event. One is the mystical version - God exists, he is angered at the
people of Earth for their sinful ways, he destroys Earth (or the entire
universe) in his rage. The alternative version is that our planet doesn't
actually exist as a physical entity - we exist in a virtual reality
simulacrum (we might be biological entities hooked into
a virtual reality system, a la The Matrix, or we might simply be complex
computer simulations). In this case, the plug could literally be pulled on the computer, and thereby our
world. It's very hard to guess at the likelihood of these scenarios.
Category: Natural Death
Super
Volcano: There are
a small number of so called "super volcanos" on
Earth. Every million years or so one of these erupts. Around 75,000 years ago, the Toba Caldera in
Indonesia erupted, and sent enough ash and sulfur dioxide into the air to affect the global
climate. This is believed to have resulted in the deaths of over 50% of
the humans alive at the time. Many geologists believe that the Yellowstone
Caldera is overdue for a massive eruption. That
said, the odds of such an eruption happening in the next
few hundred years are incredibly low.
Asteroid Impact: Asteroid impacts are believed to have caused
the extinction of the dinosaurs, and they may have been responsible for some of
the other mass extinctions in Earth's history. An asteroid large enough to wipe out human civilization might
have as high as a 1/300 chance of hitting us in 2880. Furthermore, we
haven't charted many of the comets and asteroids that could potentially hit
us. That said, the odds of significant harm to our species from an
asteroid impact are extremely low for the foreseeable
future. A slightly greater threat is that many nuclear nations don't have
the technical capacity to tell an asteroid explosion from a nuclear
explosion. In a tense situation, it's slightly possible that an asteroid
entering our atmosphere could trigger a nuclear war.
Gamma
Rays:
Gamma Rays are thought to be a possible
cause of the Ordovician Extinction roughly 450 million years ago. A large
spike in the quantity of Gamma Rays hitting Earth could destroy the ozone layer
- leading to the extinction of many terrestrial
species. Both Supernovae and Gamma Ray Bursters can produce such a
spike. Furthermore, this could occur without much warning. That
said, there is no reason to assume that this sort of event will occur within the
next several million years.
Epidemic: While bioterrorism is the greatest biological threat to our species, a
natural pandemic remains a real possibility. The Black Death killed over
1/3 the population of Europe. Many infectious disease experts believe that
we are overdue for a flu pandemic. Some strains of the Ebola virus have
mortality rates near 90%. If such a disease becomes easily
transmittable between humans and has a decently long incubation period -
then it could sweep the globe. The same is true of many
new antibiotic resistant bacteria that we've created by the indiscriminate abuse
of antibiotics. All in all, a pandemic is not unlikely during the next
several decades - although the odds are that it won't be deadly enough to cause
the collapse of society.
We Don't Exist and Other Philosophical Twaddle:
It's surprisingly hard, if one has any doubt, to prove that we
exist. And, if we do exist, we really can't demonstrate that we have a remotely accurate conception of
reality. We can't even know whether the universe, if it exists, follows a
logical set of rules. All of this is pretty irrelevant to the practical realities of life - we basically
have to take it all on faith. But, it is possible that we could one day
realize that we don't actually exist, or that one person thinking the wrong
thoughts could sort of wake the universe up to our non-existence, and thus end
our illusion of existence. In any case, while it's impossible to quantify
the likelihood of this sort of possibility, we also probably don't need to worry
overmuch about it.
