Greenland Ice Poisoned The Romans?

  It is believed that a modern civilization has a destructive effect on nature, and in the distant past harmony with the environment is not compromised.
   This is untrue. In ancient times Lavrionskie silver-lead mines reputed real scourge of Attica.
   Small peninsula south of Athens was literally dug hundreds of mines, where countless masses of slaves left to languish in the dark tunnels or stunted by the light of day in the sulfurous fumes and lead smelters.
   From gas plants dried up, from scrubbing water every living thing perished in the streams, forests have been cut around the needful same insatiable furnaces.
   As demonstrated by drilling the Greenland ice sheet, those of its layers, which are deposited at the time of the Roman Empire, the highly contaminated with lead – it settled about 400 tons.
   Metal production center is located in Spain: and yet from it to Greenland – 4000 km! Assuming that the atmosphere averaged about 5% of mined lead, we can estimate the value of its output: up to 80,000 tons per year!
   Spain has been downright suffocating in the lead dust. In addition, a lead throughout the Roman Empire did sheet roofing, water pipes, the nucleus for a sling, signs, writing, jewelry, pottery, cosmetics and even sweetening the foods “lead sugar” pretty poisonous. Mass poisoning is considered one of the reasons for the fall of Rome.
   But, of course, the extent of human influence on the nature of a bygone era did not compare with its current exposure to it.
   So, the whole mass of ancient lead in the ice of Greenland is only 15% of settled lead dust on top of her twentieth century. In general, these signs of uncontrolled automobile exhausts.
