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.)

What would happen if we upload our brains to computers | Robin Hanson

Meet the "ems" -- machines that emulate human brains and can think, feel and work just like the brains they're copied from.
