Rainforests have some of the most complicated soundscapes on the planet. In this dense noise of insects, primates, birds, and everything else that moves in the forest, how can you detect the sounds of illegal logging?
The old cell phone you have sitting in your desk drawer may have the answer.
How do you go about saving the rainforest with old cell phones?
After a visit to the rainforests of Borneo, physicist and engineer Topher White was struck by the sounds of the forest. In particular, the noises he couldn’t hear.
While on a walk, White and others came across an illegal logger sawing down a tree just a few hundred meters away from a ranger station.
This incident set White thinking that perhaps the best way to save the Earth’s precious rainforest is to listen to its loggers and poachers. The innovation he came up with, Rainforest Connection, uses old cell phones to help to save the planet in a big way.
