Dr. Doom, On Space Travel
From the beginnings of human history, we have been steadily moving Into previously
unoccupied territories, conquering and taming them as we go. In the olden days, the
adage was "Go west, young man, go west." This worked until we finally ran out of
wilderness when west met east. Western Australia is as far west as you can go now.
West- wards from WA is the East. And so, we have encircled and conquered the entirety
of planet Earth.
Over 30 years ago, late in 1972, TIME magazine published an article suggesting that
a manned space flight to Mars might be possible. I went on record with a letter to the
editor, published on January 1st 1973, as follows:
"Sir / Instead of six sex-starved men, let's send up three mated pairs (women
astronauts are long overdue), people with a real pioneering spirit, and populate Mars.
One hopes that Martian-born humans will benefit from our lessons on earth and take
better care of their planet!

Science fiction has played a prominent role in our lives and many are convinced that
humans will ultimately leave Earth and travel throughout the Cosmos. Shows like Star Trek
encourage this fantasy, but few people have given enough thought to how totally dependent
we are on other life forms, let alone how tied to Earth we actually are. First, and foremost,
we are, and will always be, Earthlings. For humans to exist for long periods in outer space
will require complex life support systems well beyond those currently available. In addition
to controlling things like temperature, gravity, and gases, we must eat, and food cannot be
created in magical replicator boxes as depicted on TV. Rather, we will have to find means
of growing food on space ships. This will require much more space than anticipated, probably
more than is possible. Attempts at constructing self-contained biospheres here on Earth have
been limited but so far all have failed.
If we can, we ought to get to Mars while we still can. Some brave Pioneering souls should
go out on a one-way spaceship to Mars. They will have to build themselves a greenhouse to grow
their own food and hold in and recycle oxygen and water and figure out how to survive in a
hundred degrees below zero, whatever it takes. We should take the Library of Congress up with
us on DVDs so that when humans wink out in this little sphere, there will be a record of what
happened here on Earth somewhere else.
On that new planet, a book little kids read in kindergarten will be "The Rape of Earth," its
lesson will be let's treat our new planet better. But, based on past experience, it does not
look as if humans learn from mistakes.
Certainly, conquest of space and getting humans and human knowledge off Earth is desirable
and something we should strive to accomplish before we destroy this planet and everything on
it. A great deal of energy is required to break free of the gravitational bonds of Earth, so
very few of us will be among the chosen few allowed to escape its bonds.
Although, in the early 1970's, I suggested mated pairs of brave pioneering colonists, it now
seems more prudent to send only young females out to colonize space, well supplied with banks of
frozen sperm from highly qualified males, so that genetic variability could be maintained in the
long term. Even though males and their y-chromosomes wouldn't be among the first chosen to leave
Earth, they would nevertheless be born off planet and thus represented in future generations.
Imagine, men who have never seen or lived on Earth!
If and when humans finally do depart from Earth, almost all of our descendants will remain
stuck here crowded together deadlocked in a hopeless stalemate, competing for what (if any)
limited resources remain.
In this stalemate, those of us who do care about Earth, by living an ecologically sensible
low impact life, in fact, are merely allowing those who don't care to continue raping the planet.
Unfortunately, even if you do all you can to minimize your own footprint on Earth, many others
will not. Cleaning up the trash along highways merely makes things seem better and fosters
litterbugs.
Educated people tend to have fewer children than uneducated people. Garret Hardin pointed
this out, and said those who don't have any conscience about the Earth are going to inherit
the planet, because those who don't care are leaving more progeny than those who do care and
make fewer babies. And so human conscience is on its way out -- if we persist on our present
course, we are going to evolve into uncaring humanoids. That's probably already happening and
IQs are falling for the same reasons, too [Herrnstein, The Atlantic, May 1989 v263 n5 p72(7)].
Humans could be Gods, real stewards of this planet, but the disparity between what we could
be and the pitiful creatures we actually are is the real tragedy. If only more people would try
to live up to their full potential.
