Oil is the First Wave of an Even Bigger Problem
Even if we do manage to dodge the oil-and-gas depletion
bullet, then comes a coal-depletion bullet, and a bullet for depletion of
fertile land (well under way), and more bullets for depletion of silver,
platinum, nickel, crystals, marble, limestone, etc etc. For all the precious metals
– silver, gold, platinum, palladium, rhodium etc – the "mother lodes"
are long gone. Nowadays we are searching and digging for 5 ounces of metal per
ton of dirt! It hardly deserves to be called "ore" anymore.
Of everything we use, much cannot be recycled because we've spread it around so
thinly. If we can't recycle such tiny quantities now, we certainly won't do it
when energy supplies become limited and very expensive. For example, the
miniscule quantities of precious metals in computers may never be recoverable.
Imagine a future in which we have a limited quantity of some metal, and we work
hard to recycle. Suppose we lose just 10% of this metal each year (today it's
much worse). Then, every year we must produce 10% fewer goods, for lack of the
metal. After 30 years of this, there's only enough metal left to make 1/20th
the number of devices we started with. "Who gets the new TV this year?"
In other words, from the moment we can't dig up more metal, our challenge will
be to recycle all of it, and I mean all of it; or we will reverse the entire
Industrial Revolution within one generation. The clock starts ticking for all
minerals at once, when we "can't dig up more" because there's
insufficient energy for the digging. That becomes a real threat as soon as oil
shortages begin.

I have long been an advocate of renewable energies. But you have raised an extremely important issue: Oil is just one of hundreds of non-renewable resources. It is funny how one can so completely ignore all the items in a store when everybody talks about just the gooey black stuff.
I will surely look into this in great depth in the near future! Unfortunately it is just one more seemingly-impending disaster awaiting our species just around the next corner. As if we haven't had enough troubles lately! But it would be universally foolish to ignore the growing scarcity of our planet's natural resources.
Thanks for keepin' it real.
