Do you have a drawer somewhere filled with old cellphones collecting dust? Wouldn’t it be great if there were a way to put those phones to good use? This week’s guest on Sea Change Radio, Topher White, is making a difference using those dormant phones. His organization, Rainforest Connection up-cycles defunct phones with solar charging technology and then places them strategically in rainforests all over the world to monitor human activity like poaching and deforestation. After listening to how Rainforest Connection is making use of old phones, you may find yourself digging around that drawer to see what you’ve got to send them.
