Copper production and the fall of empires


This is a chart which seems to show that empires decline well before they fall, as shown by a sharp drop-off in copper production before the end.

I am absolutely not qualified to judge whether this is based on plausible information. If you know some appropriate history, what do you think?

Interesting, this also matches the the pattern of farming efficiency, specifically weight of wheat[or grain] produced per hectare...

Which raises the question, is the decline a product of mismanagement leading to reduced efficiency, over-use of resources producing the decline, or something else...?

Of course, it could be a combination of resource exhaustion and mismanagement.
