Severn Cullis-Suzuki’s speech at the 1992 Earth Summit in Rio caught the attention of the world. As the daughter of environmentalists David Suzuki and Tara Cullis, Severn's concern for the environment was fueled by a trip to the Amazon rainforest at age nine. Back home in Vancouver, she and her friends started ECO, the Environmental Children’s Organization, combining their efforts to raise enough money to travel to Rio. They couldn't have imagined the effect they would have on the adults gathered there. More than twenty years later, Severn's speech continues to receive thousands of hits on YouTube. Severn’s story is about the power that children have to create change when they work together, and how their voices can stand out above the politics and cynicism of adults.
