Why saving a whale might require dismantling 500 miles of infrastructure
In short: This documentary explores the desperate struggle to save Cascadia's orcas by addressing a root cause far from their habitat. It highlights the intersection of marine biology and high-stakes politics in the Pacific Northwest.
For millennia, this unique population of killer whales has relied on Chinook salmon along the U.S. Pacific Coast. However, over the last 40 years, scientist Ken Balcomb has documented a lethal cycle: as salmon populations collapse, the orcas face starvation.
The proposed solution involves removing four fish-killing dams located 500 miles away on the largest tributary of what was once the world's largest Chinook-producing river. The film examines the friction between scientific necessity and the political dominance of hydropower in the region.
