The phenomena of the loss or decline of a species, resulting in the loss or endangerment of other species that depend on it, leading to cascading effects across trophic levels.

"Captivating images of the Salish Sea tell a tale of epochal survival for its apex species: the southern resident killer whale. From the northern edges of Vancouver Island to Oregon’s Lower Snake Rivers, two passionate filmmakers connect with activists, Indigenous leaders, and renowned scientists to understand the fate of the orcas and find solutions to our most pressing environmental threats. A vital, eye-opening analysis of interdependence, humbly offering the next generation a conscious path forward.

In August, a United Nations climate change report issued a “code red for humanity.” Yet the alarm had already flashed red for young conservationists Gloria Pancrazi and Elena Jean as the world witnessed an orca carry her deceased neonatal calf along the ocean surface for 17 days. Called to action, this sprawling debut documentary evolved into a justice-driven dissertation on the science, politics and myriad systems that must be in equilibrium to sustain life in this ecosystem."
