Thought for the month
“You always own the option of having no opinion. There is never any need to get worked up or to trouble your soul about things you can't control. These things are not asking to be judged by you. Leave them alone.”
Marcus Aurelius Antonius, Emperor and Stoic philosopher (121-180).

Pending material shortages?
The geologists do have concerns over the limits to material availability but this stems not so much from the fear that resources will run out. The so called "peak metal", the anticipated turning point from globally increasing to decreasing production when minable deposits become scarce, is not yet in their view on the horizon. The bigger issues being demand surges coming up against political/monopolistic actions by governments or companies thus causing bottlenecks and shortages. Building more mines is one approach but the social and environmental consequences are non-trivial.
