Imagine a group of young people who gather by a river to pick up trash and learn about the ecosystem that thrives there. These aren't just ordinary summer activities; they are part of a growing movement of youth-driven ecological preservation. How are young people in China and around the world stepping up to protect our planet? From participating in clean-up efforts to leading educational initiatives, how are they contributing to a more sustainable future? On the show: Niu Honglin, Yushun & Steve Hatherly
