6. Population Decline (Depletion)
Fitted to population data between 1950 & 2006

7. Iron-Ore-Extraction Depletion

12. Manganese-Extraction Depletion

13. Salt-Extraction Depletion

14. Tin-Extraction Depletion

15. Zinc-Extraction Depletion

16. Mercury-Extraction Depletion

17. Mercury is the only one truly depleted.
The rest are “depleted” only because of the depletion of fossil fuels.
