Who cares—about the environment, poverty, animal trafficking, and healthcare? Who are the people who have committed their lives to helping others in need? A documentary from Brazilian filmmaker Mara Mourão aims to unveil them: the world’s social entrepreneurs, who start social causes instead of businesses. The film highlights a dozen or so of these individuals, who range from doctors to economists to clowns, but whose missions aren’t all equally hard-hitting: While Muhammad Yunus, the Bangladeshi banker and 2006 Nobel Peace Prize recipient, is certainly inspirational when he discusses the origins of microcredit and how the poorest people in his country benefit from his work, you might cock your head at the clowns who visit kids in Brazilian hospitals. Still, there are moments that might make your heart bleed. By the end of the film, the people who care might just be the viewers.
