The captivity of orcas in marine parks has been one of the most publicly contested animal welfare debates of the past thirty years. Scientific evidence consistently shows profound welfare deficits in captive orcas.
The welfare case against orca captivity is among the strongest for any single species. The combination of extreme spatial restriction, social disruption from non-natural groupings, acoustic stress in confined pools, and psychological effects of repetitive performance creates chronic welfare deficits. The successful public campaign against orca captivity demonstrates the power of compelling, evidence-based advocacy to change industry practices and cultural norms.
