HookeRL (2000) estimates 6 tons of material (earth, rock, etc.) is moved per average person per year(1). With 7.5 billion on us, ~45 Gt/yr were moved. Much of this movement may be of coal overburden and low-grade ore.

As ore grades drop while living standards rise, I expect the tonnage moved per capita-year will rise year-by-year. Is this quantified anywhere citable?
