Without the Amazon, the world as we know it ends. With no hyperbole, it is the churning epicenter of weather systems worldwide. It creates rain. It regulates temperature and humidity. It stores carbon dioxide. It regulates trade winds from the Atlantic Ocean and all the moisture they move. It releases around 20 billion tons of water into the atmosphere every single day. It supports ecosystems not found anywhere else on the planet. And we know next to nothing about most of what lives there. The XPRIZE Rainforest competition’s 2024 winner, Team Limelight, aims to change that, to show all of us that the planet’s greatest buried treasure is worth fighting for. And that the time to fight is now.

In this second installment of a two-part special Rio G20 series, host Tate Chamberlin interviews Team Limelight Rainforest’s Dr. Thomas Walla, Professor of Biology at Colorado Mesa University, and Outreach Robotics Cofounder Guillaume Charon, two among the many creative minds intent on tackling the world’s most pressing concerns in XPRIZE competitions around the globe. Here, they break through the Amazon’s canopy to shed light on the world’s most misunderstood treasure and all the sway it holds over the future of literally everything.
