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.
