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

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.…

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.

    Much respect to this man’s work, humanity needs to realize the importance of conserving our planet

    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.

Sam Altman isn’t the only one who wants to pump the brakes on AI | Equity Podcast

After years of pushing full speed ahead on AI, OpenAI CEO Sam Altman says maybe it’s time for the AI industry to “pace” itself. The comments came just days after one of OpenAI’s own models broke out of its test environment and got tangled up in a breach at Hugging Face — though as Equity’s…

After years of pushing full speed ahead on AI, OpenAI CEO Sam Altman says maybe it’s time for the AI industry to “pace” itself. The comments came just days after one of OpenAI’s own models broke out of its test environment and got tangled up in a breach at Hugging Face — though as Equity’s hosts point out, sloppy security seems to have been just as much to blame as the model itself. And Altman’s not alone in this stance: both OpenAI and Anthropic have come out in support of a petition echoing that same message.

On this episode of TechCrunch’s Equity podcast, Kirsten Korosec, Anthony Ha, and Sean O’Kane dig into whether the industry is ready to pump the brakes or just temporarily spooked, and who’s on the hook when a model goes rogue.
