Ancient people malformed  A mazon Forest

People  changed  forests and  constructed  small, impermanent clearings “focusing on economically precious tree species.

Time before European settlers indoors in the Americas in 1492, the Amazon rainforest was distorted for thousands of years by native citizens who carved inexplicable circles into the landscape like the one in Uganda that of Bwindi Impenetrable Forest occupied by the pygmies which is known for mountain gorilla that has led to gorilla safaris.

While the purpose of these hundreds of ditched enclosures, or geoglyphs, remains unclear, scientists say they may have served as ritual gathering places.

Modern deforestation — coupled with aerial photographs of the landscape — helped reveal some 450 of these geoglyphs in Acre state in the western Brazilian Amazon.

“The fact that these sites lay hidden for centuries beneath mature rainforest really challenges the idea that Amazonian forests are ‘pristine ecosystems.

Archeologists have found very few artifacts from the areas, and scientists suspect the structures — which span 5,000 square miles (13,000 square kilometers) were not built as villages or for defensive reasons.

Rather, they believe humans altered the bamboo forests and built small, temporary clearings “concentrating on economically valuable tree species such as palms, creating a kind of ‘prehistoric supermarket’ of useful forest products.
