This Afghan Teen Was Set to Join First-Ever U.N. Youth Climate Summit, But U.S. Denied His Visa

Climate youth activist Nasratullah Elham of Afghanistan was invited to participate in the first-ever U.N. Youth Climate Summit, but the United States rejected his visa. He breaks the sound barrier to join us from Phuket, Thailand, where he is a 12th grade student, and says his activism is based on the crisis's impact on his home country. "The poor people there are very badly affected in a situation [where] they do not really have much carbon emissions," he says.
