The Amazon rainforest is the largest and most species-rich tropical rainforest in the world. It is also one of the areas most seriously damaged and destroyed. Today, in the Amazon rainforests of Brazil, Peru, and Ecuador, an old smart phone emerged. And solar cell monitoring devices help prevent deforestation and other deforestation.
San Francisco-based non-profit organization Rainforest Connect restructured the recovered old smart phones and used 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 sounds in a radius 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 activated 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, so it can also be used to fight poaching. 'Rainforest Link' staff installed the equipment on a hidden canopy at regular intervals. Solar cells ensure that Uninterrupted power supply is also available at night and on cloudy days. Once the device is stolen or removed or removed by the poacher, the program will automatically send emergency alarm messages.
Toff White, the founder and CEO of Rainforest Connect, stated that the 'Guardian' has successfully prevented many cases of pirating, and it helps 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 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 felling in major tropical regions (Amazonas, Congo Basin, and Southeast Asia). Deforestation has led to a reduction in forest area, One of the important reasons why greenhouse gas emissions and biological diversity are threatened.
The total area of the Amazon rainforest is about 700 million square kilometers, accounting for half of the world's rainforest area, and 20% of the world's forest area. It is called the 'Lung of the Earth' and plays an important role in maintaining global ecological and climatic balance. However, due to its vast footprint, And across multiple countries, it is difficult to protect.
