For example,
this boob, who are clearly a college graduate, for whom mines excavate and unearth miraculously all by themselves:
But for all those years, the source material for the arguments have [sic] remained largely the same. ...
A team of archaeologists, historians, and climate scientists have [sic] constructed a history of Rome’s lead pollution, which allows them [sic] to approximate Mediterranean economic activity from 1,100 b.c. to 800 a.d. They [sic] found it hiding thousands of miles from the Roman Forum: deep in the Greenland Ice Sheet, the enormous, miles-thick plate of ice that entombs the North Atlantic island. In short, they [sic] have reconstructed year-by-year economic data documenting the rise and fall of the Roman Republic and Empire. ...
But these mines didn’t excavate [sic] pure silver: Instead, they unearthed [sic] an ore of silver, lead, and copper that had to be smelted into silver. ...
Once in the air, these lead emissions did not stay in one place. Instead, it [sic] wafted with the winds, eventually blowing into squalls and storms over Greenland. ...
The Crisis of the Roman Republic—the series of civil wars and political strife, spanning 134 b.c. to 27 b.c., that brought the Roman Republic to an end— were [sic] associated with a broad period of economic stagnation and disintegration, the study finds. And the early Roman Empire—especially the Pax Romana, the 206 years of mostly uninterrupted peace throughout the Mediterranean—were [sic] accompanied by an economic boom. ...
These simulations allow scientists to estimate how air from the Iberian peninsula—air that, in Roman times, would have been full of lead pollution—wafted up to the Greenland ice sheet. It [sic] also allowed them to distinguish between air from the Iberian peninsula specifically and ambient air from farther east in Europe.
