The thrill of not knowing all the answers | Harini Bhat

Impact investor Tom Chi challenges a dangerous assumption: that economic growth and ecological health are opposing forces. He reveals how advances in AI and robotics are enabling a radical shift towards innovation as a force for restoration. Imagine mines that extract less, farms that regenerate soil and fleets of robots that can plant 100,000 mangroves in a single day. What if the same technologies that power our economy could actively repair the planet at the same time? Hosted on Acast. See acast.com/privacy for more information.

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.) Hosted on Acast. See acast.com/privacy for more information.
