I don't think the point Mr. Czech discusses is quite a trivial truism,
since one can point to cases where technological advances can indeed limit
the consumption of resources, or otherwise lower environmental impact.  For
instance, LED lighting uses less engergy than incandescent lighting.  Given
that such cases exist, it is reasonable to ask how much, across the whole
spectrum of technology and the economy, can technologies reduce
environmental impact.  Additionally, there may be technologies that
actually mitigate environmental damage already inflicted.  Thus,
mathematically at least, it might make sense to speculate that
environmental impact can be greatly reduced, if not set back to zero (and
if there is a technological breakthrough that can substantially reduce
human population, hey, maybe even to zero).

I think, however, that Mr. Czech does not use his thousand words very
efficiently to make his point, since the article is rather too chatty and
short on substance.  Additionally his example of wrenches to tighten nuts
is not very helpful and is based on a faulty understanding of the history
of wrenches.

The first wrenches were military tools used to twist the bars out of the
portcullises of castles.  These wrenches were of necessity open-end
wrenches since the attackers had access the bars from the side; they
couldn't count on sliding the wrench over the end of the bars, as one must
do with a box-end wrench.

Box-end wrenches became popular with the rise of the machine age, because
in many cases the nuts and bolts of machines can be accessed from the end.
These wrenches justify the name "box end" because they had a simple square
of iron at the end of the iron rod that served as the handle.  When hex
nuts became popular, that gave rise to the six and twelve-point wrenches
(whose nut-fitting part no longer looks like a box) that we today call
box-end wrenches.

However, the monkey wrench, which Mr. Czech implies was used first on nuts,
was a later development than the box-end wrench because it has a relatively
complex screw-based adjustment system that was much harder for a blacksmith
to make than a simple box on a rod.  The monkey wrench is probably a good
example of a technological development that lowered environmental impact,
because its adjustable nature let a mechanic have just a few wrenches
instead of one for every possible nut size.

Interesting, huh?
