Reflections on Warmth: Cooperate with the Sun and Move Up
the Evolutionary Bench
Clarke Snell encourages us to make
friends and play nice with our planet’s natural heater.

All right, let’s review our progress. There was this big
bang. Matter flying around. E=MC2. Galaxies, stars, planets coalesced.
In our hood: primordial soup. The miracle of life. Ontogeny sort
of recapitulates phylogeny. Amoebas, walking fish, and then, finally,
our peeps the protohumans hit the scene. Until about 1.5 million
years ago, we were homo habilis, i.e. “handy man,”
because we had tools. Makes sense. Then, for about a million years,
we were homo erectus, or “standing human.” I’ll
buy that. Save for a few anomalies like homo heidelbergensis (Heidelberg
man…no really, look it up), for the past 250,000 years we’ve
supposedly been homo sapiens, or “wise human.” Now,
based on our present situation (global warming, constant war,
Britney Spears), I think it’s pretty clear that the naming
committee was a bit optimistic on that one. Though we may pull
together and reach the sapiens level, we clearly need a new name
for the past 250,000 years of humanity. My proposal is homo controlfreakus.
As far as I can tell, the core of much of human activity seems
to be control. Industrial agriculture is our attempt to control
plants. War is our attempt to control each other. A city is all
about control: a unilateral and hostile takeover of an indigenous
ecosystem by a single species (you guessed it, homo controlfreakus).
And then it gets weird. Have you heard they are inserting a spider
gene into a goat to get spider silk in milk?! Then there’s
my personal favorite: the human-rabbit embryo. No, that’s
not a Halloween costume. It’s science.
Though technologically advanced, the controlfreakus approach is
comically simplistic. It sees the world as an eighth grader’s
chemistry set waiting for experiments, and the results are often
sadly predictable. Kudzu is a great visual aide for this point.
You know, that carpet masquerading as a plant you see draped over
acres of former forest and farmland around our region. This vine
was intentionally taken from its native ecosystem in Japan and
introduced into this country as a forage crop. The U.S. government
used to plant it and encouraged farmers to do likewise. Unfortunately,
our climate turned out to be too much of a good thing for Kudzu,
and it dominates wherever it takes hold. Now, that same government
recommends pesticides to deal with this “invasive species”
that reportedly costs us $500 million annually in lost cropland
and attempted control measures. I would argue that our present
struggles with melting ice caps and the invasion of Iraq are cut
from the same cloth. Homo controlfreakus sees the world as hostile,
disjointed and flawed. Consequently, he (or less often she) barrels
ahead with shortsighted goals of short-term gains and no concept
of the overall context.
That “context” is the almost infinitely complex, exquisitely
fine-tuned feedback loop that is this planet. In order to prevent
more kudzus, Chernobyls and drowning polar bears, we just need
to heed the old saying, “If a planet ain’t broke,
don’t fix it.”
Okay, that’s cute, but what does it really mean? Well, since
this month New Life Journal’s focus is on warmth
and rejuvenation, let’s take the problem of heating a building
as an example. On Planet Earth, fluctuations in temperature are
almost solely the result of the relative exposure to sunlight.
What’s more, the Sun’s path through the sky changes
throughout the year in an annually repeated pattern so that we
can know exactly where it will be in the sky relative to our planned
building at any given minute of any given day. Obviously, then,
our starting point in considering a heating strategy will be to
determine how the Sun will interact with our building. This concept
is called passive solar design and is: (A) the default design
process for any new building or (B) a fringe concept that comes
in and out of style but never seems to catch hold?
The inexplicable answer is (B.) The really weird thing about this
is that almost all of the energy we use to run our modern technological
society already has a solar origin. Photosynthesis turns sunlight
into plant tissue. That tissue in turn is metabolized to create
animal tissue. When compressed and naturally “processed”
for millions of years, these materials become coal and oil, which
we then burn to move cars, heat houses, create electricity, drop
bombs, etc. More direct uses of solar energy are burning wood
and other plant tissues. The Sun is also the engine behind air
movement and the hydrologic cycle, so it’s the source for
wind and hydro-powered electricity generation. Of course, the
Sun is also the source of power for photovoltaics, the direct
generation of electricity from sunlight.
Yet, if you analyze our use of these various forms of solar power,
it seems like the less direct the access, the more we depend on
it. We go to bizarre lengths to harvest ancient sunlight in the
form of oil, gas and coal when the direct source of that power
is the most available natural resource around. Why? After a lifelong
study of homo controlfreakus, my theory is simple: direct use
of the Sun is basically a humble undertaking. You can’t
tell the Sun where to be and when to shine, so you have to accept
limitations and work to maximize positive effects of existing
realities. Your goal is to cooperate, cajole and enhance. On the
other hand, even though coal, oil, and gas are very hard to access,
they represent concentrated sunlight that can be taken out of
context, thus removing limitations…at least in the short
term. You can have waterfalls in the desert of Phoenix, snow skiing
in the heat of Dubai, and build houses and cities on a grid disregarding
the path of the Sun. On the surface at least, you are in control.
Unfortunately, this childish outlook won’t work in the long
run. For one thing, like any harmful addiction, this will eventually
kill us. Our solar control addiction is creating climate-changing
pollution and is fueling wars as we speak. Even if the planet
and our society could hold out, our supply won’t. These
materials take millions of years to produce, so we can’t
make more of them. It’s really pretty simple. Right now,
it’s the Sun and millions of species of life on one side
working together and one lonely little species on the other trying
to stand up for its right to party. Come on, my fellow controlfreakians,
let’s move up the bench toward homo sapiens status. A good
start is a transition from trying to control the Sun to basking
in it.
