Wednesday on Worldview:

More young people in developing countries die in traffic accidents than from HIV/AIDS or malaria. Worldview looks at global traffic safety with Bella Dinh-Zarr, the North American director of the Make Roads Safe campaign, and Greig Craft, founder and director of the Asia Injury Prevention Foundation, an organization that has helped save thousands of lives in Vietnam and other developing countries by advocating for helmet regulations.

Then, Chile has a long-standing tradition of activist singer-songwriters leading entire musical movements in Latin America. On Global Notes, Jerome McDonnell and contributor Catalina Maria Johnson listen to some seminal Chilean artists performing in Chicago this summer.
