[Aztlan] The Nazca self destructed

[michael ruggeri]

Listeros,

Archaeologists studying the Nazca have found that they self destructed  
by destroying their forests around 500CE. The study was posted in the  
journal Latin American Antiquity. The Nazca cleared too much forest  
for agriculture and the Huarango tree was replaced by cotton and  
maize. The tree was crucial to the desert's fragile ecosystem and held  
the Nazca irrigation canals in place. An El Nino flood then devastated  
their area. The tree was needed for food, forage, timber and fuel and  
enhanced soil fertility and moisture and its deep roots held down the  
soil.
Once the flood happened, the harsh desert winds then completed the  
destruction of Nazca culture.
