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.

The Despacio tent is a temple of music for audio geeks, and the brainchild of LCD Soundsystem frontman James Murphy, Stephen and David Dewaele of 2manydjs aka Soulwax, and audio engineer John Klett. First created in 2013, Despacio makes its way from festival to festival, blasting dancers with vintage vinyl from seven McIntosh speaker stacks that make up the 50,000-watt sound system along with the lighting rig and iconic disco ball that complete the experience. CNET social producer Faith Chihil got a chance to catch it at Portola Music Festival in San Francisco and here’s what she found. #despacio #portolamusicfestival #festival #audiophile #vinyl

It’s not AI anymore, it’s ‘super intelligence’ (according to the White House) | Equity Podcast

This week, the White House got nearly every major tech CEO in one room — Zuckerberg, Bezos, Musk, and Anthropic’s Dario Amodei among them — to sign an AI safety pledge that President Donald Trump called “morally binding.” Trump also signed an executive order officially rebranding AI as “super intelligence,” and meanwhile, Meta and OpenAI…

This week, the White House got nearly every major tech CEO in one room — Zuckerberg, Bezos, Musk, and Anthropic’s Dario Amodei among them — to sign an AI safety pledge that President Donald Trump called “morally binding.” Trump also signed an executive order officially rebranding AI as “super intelligence,” and meanwhile, Meta and OpenAI are putting friendlier faces on their AI products, even as the biggest money in AI still appears to be coming from the enterprise.

On this episode of TechCrunch’s Equity podcast, Kirsten Korosec, Anthony Ha, and Sean O’Kane dig into this week’s AI moves, the ugly economics of consumer AI, plus the shifting IPO market and a handful of startup deals.
