Scientists say the conquest of the Incas caused air pollution in South America to spike
from Fox News
The Spanish conquest of the Americas brought about the demise of such civilizations such as the mighty Incas and Aztecs, ravaged indigenous populations through disease, warfare and slavery, all but erased many important historic and cultural artifacts ... and changed the climate of the Americas? That's what researchers at Ohio State University are suggesting in a study on the Quelccaya ice cap in Peru published in Proceedings of the National Academy of Sciences. The study says long before smog had settled over Los Angeles and Mexico City and factories from Shanghai to Chicago pumped toxins into the atmosphere, the Spanish were helping contribute to climate change thanks to their lust for precious metals.
