Parkland shooting survivors call for a march on Washington, D.C.

They will be heard.

Less than a week after the tragic mass shooting at Marjory Stoneman Douglas High School that left 17 dead, survivors have announced a march on Washington D.C. to demand an end to gun violence.

The call went out on Sunday morning talk shows, the BBC reports, with students and parents coming together under the banner of March For Our Lives. Planned for March 24 in both D.C. and in other communities around the country, the goal is to force collective action on gun control.

"Not one more," reads the group's mission statement. "We cannot allow one more child to be shot at school. We cannot allow one more teacher to make a choice to jump in front of a firing assault rifle to save the lives of students."

One survivor, 17-year-old Cameron Kasky, published a CNN op-ed detailing his horrifying experience on Feb. 14 and insisting that enough is enough. If the politicians won't do anything about gun violence, he argued, then he and those like him will vote them out.

"I'm just a high school student, and I do not pretend to have all of the answers," he wrote. "However, even in my position, I can see that there is desperate need for change — change that starts by folks showing up to the polls and voting all those individuals who are in the back pockets of gun lobbyists out of office."

The March For Our Lives website calls for a national response to what its organizers recognize as an ongoing national tragedy. The page provides a form for would-be marchers to sign up to receive updates, and clearly aims to build a lasting coalition dedicated to gun control.

"We cannot allow one more family to wait for a call or text that never comes," the mission statement continues. "Our schools are unsafe. Our children and teachers are dying. We must make it our top priority to save these lives."
