Eleven-year-old Itzcuauhtli Roske-Martinez undertook a 45-day vow of silence to demand action toward climate change at the end of October 2014. He received support from youth around the world, as well as actor and climate activist Mark Ruffalo, who called his campaign “brave and thoughtful.” Itzcuauhtli is proving that anyone can make a difference when they are passionate about an issue. “When I say world leaders, I’m talking about us,” he said.
