Using stunning time-lapse photography and underwater footage taken over the course of seven years, this film shows how a traditional way of life is being ravaged by environmental change. On Hudson Bay's isolated Belcher Islands, the community of Sanikiluaq has long relied upon the eider duck and their down feathers (the warmest in the world) for survival. But the runoff from nearby hydroelectric dams has disrupted an increasingly volatile ecosystem. Changed sea ice and ocean currents have triggered massive die-offs in the ducks. By reflecting on how they survived in the past, the community seeks to create a sustainable future. Filmmaker in attendance.
