The mass shooting that claimed 17 lives at Marjory Stoneman Douglas High School in Parkland, Florida has led to an important conversation about gun violence in America, as well as active demonstrations highlighting the need for gun control reform. Wednesday (March 14), exactly one month after the shooting, thousands of students nationwide walked out of class for 17 minutes in solidarity for #NationalWalkoutDay, including students at Horace Greeley High School in Chappaqua, New York.

The video above captures their reasoning for walking out, along with the overall message: enough is enough.

Survivors of the mass shooting have spearheaded March for Our Lives, which will take place March 24 in Washington, D.C., as well as across the country. You can learn more about March for Our Lives by visiting here
