resilience | We imagine ourselves to be members of a thoroughly scientific culture
and to be scientifically minded. But, what science tells us is that the
evolution of the universe and thus of planet Earth and its inhabitants
is random. It is following no predetermined felicitous course. This
process of change could be favorable to humans or it could be
horrifically dangerous to them.
Our technological innovations will not necessarily shield us from
this change. In fact, these innovations are part of the change. They
influence climate in a way that is deleterious to the human future; they
empty fisheries with a swiftness never before seen; they lead to
degradation of the soil, not in isolated areas, but worldwide; and they
poison the food, the air and the water in a manner that is global in
scale.
A friend refers to this as the Midgley Effect. Chemist Thomas Midgley Jr. was heralded for his work in creating leaded gasoline and chlorofluorocarbons.
The story of leaded gasoline is rehearsed every time we pull up to a
gas pump and fill our automobiles with UNLEADED gasoline. Lead added to
gasoline for the purpose of preventing so-called engine knocking turned
out to be very bad for human health. Big surprise!
But chlorofluorocarbons were
even worse. Used primarily as refrigerants from the 1930s onward and
later as aerosol propellants, they escaped into the air. No one thought
to track their destination until the 1970s when one scientist, F. Sherwood Rowland,
asked where these compounds ended up. They were by design inert--that
is, they didn't readily break down--so they must be somewhere.
That somewhere turned out to be high in the atmosphere attacking the
ozone layer which protects humans and other living creatures from
excessive radiation from the Sun. Had it not been for Rowland asking a
very specific question and receiving a grant to fund the answer, we
might well be living with little or no atmospheric protection from
dangerous levels of solar radiation. Such are the perils of our
technology. In this case, only one curious man stood between the human
species and widespread disaster. Chlorofluorocarbons and other
ozone-destroying chemicals were subsequently phased out worldwide by
the Montreal Protocol.
Midgley--who believed he was doing good things for society and
received many awards for his discoveries--turned out to have "had more
impact on the atmosphere than any other single organism in Earth's
history," according to environmental historian J. R. McNeill. And, it
wasn't a good impact.
One of the pillars of our modern techno-utopian outlook is that
invention is presumed to be good and should not be unduly impeded. It
turns out, however, that our own science has shown that inventions can
be potentially catastrophic.
So, now we come to the central contradiction of the modern outlook.
We rely on science. We say we believe in science. But what science tells
us about the trajectory of the universe and thus human beings is no
more complicated that what "Planet of the Apes" tells us. There is no
particular or preordained direction for the future development of humans
or the universe we live in.
Yet, the techno-utopian vision that we cling to as modern people
rejects this view even as we say our favored instrument of progress is
science. Thus, we must conclude that our dissenting party guest's reply
above--"They'll figure something out. They always have."--enunciates a
religious belief, not a scientific observation.
