Xinhua News Agency, Rio de Janeiro, May 20. The Amazon rainforest is the world’s largest and most species-prone tropical rain forest, and it is also one of the most seriously damaged and damaged areas. Today, in the Amazonian rainforests of Brazil, Peru, and Ecuador, a monitoring device consisting of old smart phones and solar cells has emerged, helping to prevent deforestation and other deforestation.
Xinhua News Agency, Rio de Janeiro, May 20. The Amazon rainforest is the world’s largest and most species-prone tropical rain forest, and it is also one of the most seriously damaged and damaged areas. Today, in the Amazonian rainforests of Brazil, Peru, and Ecuador, a monitoring device consisting of old smart phones and solar cells has emerged, helping to prevent deforestation and other deforestation.

The San Francisco-based non-profit organization Rainforest Connection retrofits recycled old smartphones and uses solar panels removed from abandoned industrial products to assemble a real-time monitoring device called "Guardian."

This device utilizes a high-sensitivity microphone to capture sound in an area of ​​approximately 3 square kilometers, and transmits the compressed sound file to a cloud server for analysis. Once the sound of a chainsaw, logging, truck, or motorcycle is captured, a pre-installed alarm program will be initiated and a text message or e-mail containing location information will be sent to the local forest protection department so that law enforcement officers can get to the scene the first time.
 The Guardian can also identify gunfire, dog puppets, and abnormal soundings of animals and can therefore also be used to fight poaching. "Rainforest Link" staff installed the equipment on a hidden canopy at regular intervals. Solar cells ensure uninterrupted power supply at night and on cloudy days. Once the device is stolen or removed or removed by the poacher, the program will automatically send emergency alert information.

Toff White, the founder and CEO of Rainforest Link, said that the “Guardian” has successfully prevented many cases of piracy and helped to collect statistics on areas and periods of high logging and poaching. Biologists and ordinary people can also listen to insects and insects from the rainforest at anytime and anywhere through their mobile application software. The organization plans to further promote this device in Africa, North America and other regions.

According to data released by the United Nations Environment Program, illegal logging accounts for 50% to 90% of all logging in the major tropical regions (Amazon plains, Congo basin, and Southeast Asia). Deforestation has become one of the important causes of the reduction of forest area, greenhouse gas emissions and the threat of biological diversity.

The total area of ​​the Amazon rainforest is about 7 million square kilometers, which accounts for half of the world's rain forest area and 20% of the world's forest area. It is called the “Lung of the Earth” and plays a significant role in maintaining global ecological and climate balance. However, due to its vast footprint and across many countries, it is extremely difficult to protect.
