Recycling old electronic devices, like cellphones, is a major challenge today, with the vast majority of them ending up in landfills. But the Tembé tribe in Brazil has found a unique new way to use those devices to help save the planet instead.

The program has been very effective and is a great use of technology that would otherwise be cast aside.
