A new way to fund health care for the most vulnerable | Andrew Bastawrous

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.

Let’s launch a satellite to track a threatening greenhouse gas | Fred Krupp

When we talk about greenhouse gases, carbon dioxide gets the most attention — but methane, which often escapes unseen from pipes and wells, has a far greater immediate impact on global warming. Environmentalist Fred Krupp has an idea to fix the problem: launch a satellite that tracks global methane emissions, and openly share the data it collects with the public. Learn more about how simple fixes to cut down on this invisible pollutant can help us put the brakes on climate change. (This ambitious plan is one of the first ideas of The Audacious Project, TED’s new initiative to inspire global change.)

Why I fight for the education of refugee girls (like me) | Mary Maker

After fleeing war-torn South Sudan as a child, Mary Maker found security and hope in the school at Kenya’s Kakuma Refugee Camp. Now a teacher of young refugees herself, she sees education as an essential tool for rebuilding lives — and empowering a generation of girls who are too often denied entrance into the classroom. “For the child of war, an education can turn their tears of loss into a passion for peace,” Maker says.
