Saving the Rainforest with Old Cell Phones

The old cell phone you have hanging around and collecting dust may have the answer.

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. And the innovation he came up with uses old cell phones to do this!

To introduce us to the innovation he came up with, here is Topher White on the National Geographic Live stage. National Geographic is promoting some incredible things, so go check them out to see what they’ve been up to lately!
