👣\"Save the rainforest\" is an environmental slogan as old as time — but Tasso Azevedo catches us up on how the fight is actually going these days. Spurred by the jaw-dropping losses of the 1990s, new laws (and transparent data) are helping slow the rate of deforestation in Brazil. Is it enough? Not yet. He has five ideas about what we should do next. And he asks if the lessons learned in Brazil could be applied to an even bigger problem: global climate change.

👁How high can you count on your fingers? (Spoiler: much higher than 10) - James Tanton
‌
🗣Subtitle: Farsi | English | Turkish
👣How high can you count on your fingers? It seems like a question with an obvious answer. After all, most of us have ten fingers -- or to be more precise, eight fingers and two thumbs. This gives us a total of ten digits on our two hands, which we use to count to ten. But is that really as high as we can go? James Tanton investigates.

👁A new way to fund health care for the most vulnerable
‌
🗣Subtitle: Farsi | English

👣In 2011, eye surgeon and TED Fellow Andrew Bastawrous developed a smartphone app that brings quality eye care to remote communities, helping people avoid losing their sight to curable or preventable conditions. Along the way, he noticed a problem: strict funding regulations meant that he could only operate on people with specific diseases, leaving many others without resources for treatment. In this passionate talk, Bastawrous calls for a new health care funding model that's flexible and ambitious -- to deliver better health to everyone, whatever their needs are.

👣As the number of “potentially habitable” planets that astronomers find continues to rise, we seem ever closer to answering the question, “Are we alone in the universe?” But should we be looking for life elsewhere?
