Teen activist and Zero Hour organizer Kibiriti Majuto is a refugee living in Charlottesville, Virginia, originally from the Democratic Republic of Congo.

Fellow Zero Hour organizer, Madelaine Tew of New Jersey, adds: "I believe that what we're doing is so crucial because it really is zero hour; we either take action now, or the future of our generation will be jeopardized by the fossil fuel industry and the dormant generations before us."
