In addition to revealing grown-ups' hopes and dreams, these songs also include tales of war, displacement, and climate change. A feature on the Arctic comes alive with surreal photographs of lives and legends frozen in time during the long polar night. Another major report looks at the fragility of North America's Great Lakes in the face of pollution and invasive species.
