Marine debris including plastic, fishing line, and ghost gear causes injury and death to seabirds through entanglement and ingestion worldwide.
Marine debris causes welfare harm to seabirds through two distinct pathways: physical entanglement causing drowning and injury, and ingestion causing gut impaction, starvation, and reduced reproductive success. The scale of plastic pollution means that most seabird individuals will encounter and potentially ingest plastic throughout their lives. Reducing plastic production, improving waste management, and removing ghost gear addresses welfare harm at the source.
