How to See (and Stop) Deforestation from Space | Tasso Azevedo | TED

Published

December 16, 2025

Nearly 20 trees are cut down every second in the Amazon rainforest, as authorities struggle to monitor millions of acres and stop illegal clear-cutting. But land reformer Tasso Azevedo and his team at MapBiomas have changed the game, transforming satellite imagery into precise, real-time maps that make every clear-cut visible — and every actor accountable. Learn how they’re helping slash deforestation in the Amazon, proving that transparency is a forest’s strongest defense. (This ambitious idea is part of The Audacious Project, TED’s initiative to inspire and fund global change.) (Recorded at TED Countdown Summit 2025 on June 18, 2025)

Interesting reminder that collaboration, more than any single tool, is what moves complex problems forward. Over 100 groups aligning on one dataset feels like a blueprint worth studying across many fields.

Confused by how much using technology and the resulting environmental degradation, energy and water use, loss of open land, etc. to data centers conflicts with the stated missions of some of these conservation talks. Are we spiraling around the same drain?

Great talk, we really need to do more globally to stop cutting down forests for farming and other heavy industries

Bravo to satellite technology and the saving of the Amazon tropical forests. Bravo to the Brazilian governmental-administration for stepping up and implementing the required corrective actions. As an American with a president who is presently destroying nearly all of our national environmental standards meant to improve life, I salute you from the bottom of my heart. Thank you for spreading this welcome information.

The Experiment That Tried to Weigh the Human Soul

It’s a little complicated to weigh a dying person on a hospital bed, but that didn’t deter Duncan MacDougall. In the early 20th century, MacDougall’s unique bed-scale detected that 21 grams left the human body at the moment of death. He had finally discovered it: the weigh of the human soul … or so he…
