This musician's quest is for clean cookstoves

Ghanaian reggae musician Rocky Dawuni is in Paris this week for the climate change summit. He's there to raise awareness how the carbon in smoke aggravates climate change. And he points out that in many parts of the world, a kitchen consists of three stones with a wood or charcoal fire below, and a pot on top to cook in. This setup is not only bad for the environment, but it's also deadly.
