Last January, we witnessed history as hundreds of thousands of men and women marched on Washington to support women as they participated in the first annual Women’s March. Now, survivors of the recent Parkdale shooting at Marjory Stoneman Douglas High School are making history of their own, taking to the streets in cities around the world as they participate in the March for Our Lives to let lawmakers know, in no uncertain terms, that the safety of students and gun violence must become a priority. They certainly weren’t alone: The march is on track to become the biggest single-day protest in DC’s history, with teachers, students, parents, and plenty of celebrities lending their support to the cause: See who we spotted below!
1. Halsey: Halsey embraced Marjory Stoneman Douglas survivor and TIME cover model Emma González, saying, “TODAY I SAW THE FUTURE WITH MY OWN TWO EYES.”
