While Xiuhtezcatl started speaking about the environment at just age 6, he is now a 19-year-old indigenous activist, musician, and the youth director of Earth Guardians, an organization that trains youth across the world to use civic engagement and the arts to help solve environmental issues. As a hip-hop artist, Xiuhtezcatl also often uses music to convey powerful environmental messages. He is also not afraid to confront the government head-on, as he was one of the 21 plaintiffs that sued the federal government for their lack of action on climate change.
