Once, the Paiter-Surui tribe(部落)lived a happy life in the heart of the Amazon rainforest in Brazil. But after the tribe’s first meeting with Westerners several decades ago, they were nearly wiped out; diseases brought by outsiders reduced the Surui’s numbers from 5, 000 to about 250.
Today, some 1, 300 tribe people live in 23 villages across 600, 000 acres. Though they are as likely to wear T-shirts and jeans as feathered headdresses, the Surui are determined to preserve and protect the tribal culture of their homeland. Now they are under threat again, from illegal logging and deforestation(滥伐), but this time it’s different. The Surui have put aside their bows and arrows and taken up a new weapon: the Internet.
The tribe people learned to use the Web from their leader, Chief Almir Narayamoga. “We decided to use computers and technology to bring attention to our situation, ”says Narayamoga, 36. The first in his tribe to attend college, Chief Narayamoga learned how to use computers at the Federal University of Goiás in Goiânia, a city of 1. 2 million. In 2007, he fled the Surui homeland after his fight against loggers who placed a $100, 000 reward on his head. He traveled to the United States and paid a visit to Google headquarters in California. He came armed with a big idea.
Narayamoga’s visit to Google was considered a great success. And Google sent teams to the Amazon to train the Surui in using computers, cameras, and smart phones to photograph logging sites, which could be pinpointed using GPS technology and then uploaded to Google Earth. The Surui have now mapped the entire reserve and recorded the biodiversity and the rainforest within it.
