Orca welfare encompasses both the well-documented harms of captivity and serious threats facing wild populations from prey depletion, pollution, and vessel disturbance.
Orca welfare harms span two very different contexts. Captive orcas experience profound psychological suffering from social isolation, inadequate space, forced performance, and shortened lifespans documented by research and advocacy. Wild orca welfare is threatened by prey scarcity forcing longer foraging, acoustic pollution disrupting communication, and persistent organic pollutant contamination causing chronic health harms. Chinook salmon recovery programs in the Pacific Northwest directly benefit Southern Resident orca welfare by restoring their primary prey.
