How to see (and stop) deforestation from space | Tasso Azevedo

How to see (and stop) deforestation from space | Tasso Azevedo

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.)

How to take a picture of a black hole | Katie Bouman

How to take a picture of a black hole | Katie Bouman

At the heart of the Milky Way, there's a supermassive black hole that feeds off a spinning disk of hot gas, sucking up anything that ventures too close -- even light. We can't see it, but its event horizon casts a shadow, and an image of that shadow could help answer some important questions about the universe. Scientists used to think that making such an image would require a telescope the size of Earth -- until Katie Bouman and a team of astronomers came up with a clever alternative. Bouman explains how we can take a picture of the ultimate dark using the Event Horizon Telescope. Hosted on Acast. See acast.com/privacy for more information.

How racism makes us sick | David R. Williams

Williams developed a scale to measure the impact of discrimination on well-being, going beyond traditional measures like income and education to reveal how factors like implicit bias, residential segregation and negative stereotypes create and sustain inequality. In this eye-opening talk, Williams presents evidence for how racism is producing a rigged system -- and offers hopeful examples of programs across the US that are working to dismantle discrimination.

A video game to cope with grief | Amy Green

A video game to cope with grief | Amy Green

When Amy Green's young son was diagnosed with a rare brain tumor, she made up a bedtime story for his siblings to teach them about cancer. What resulted was a video game, "That Dragon, Cancer," which takes players on a journey they can't win. In this beautiful talk about coping with loss, Green brings joy and play to tragedy. "We made a game that's hard to play," she says, "because the hardest moments of our lives change us more than any goal we could ever accomplish." Hosted on Acast.
