Seventeen students and staff at a Florida high school were killed in one of the worst mass shootings in U.S. history last week. Their names, however, won’t be forgotten in the wake of their classmates’ outspoken activism in championing gun control following the tragedy. Footage of Emma Gonzalez, a student at the high school where the shooting occurred, calling out politicians and urging for gun control has gone viral on social media. And students around the U.S. have been walking out of class in protest. In the end, will young people’s drive for change finally have a lasting impact?
