Marine Debris and Seabird Welfare

Marine debris causes welfare harm to seabirds through ingestion and entanglement. Understanding the scale and nature of this problem motivates effective action.

Key Facts

90% of seabirds sampled globally have ingested plastic
Laysan albatross chicks on Midway Atoll have been found with stomachs full of plastic fed by parents
Floating plastic concentrates at ocean gyres — coinciding with seabird foraging areas
Plastic ingestion causes starvation from false satiety and gut perforation
Entanglement in discarded fishing line and net fragments causes amputation and drowning

Welfare Considerations

Marine debris causes welfare harm to seabirds through two primary mechanisms. Plastic ingestion — fed to chicks as food by parents who cannot distinguish it from prey — causes starvation when plastic fills the gut without providing nutrition, and gut perforation from sharp fragments. Entanglement in discarded fishing gear causes injury and death from constriction and drowning. At the individual level, these deaths involve prolonged suffering. At population level, plastic pollution at seabird breeding sites represents a cumulative welfare crisis that is driven by human plastic production and disposal patterns. The welfare response requires both individual level action and systemic reduction in plastic production.

What You Can Do

Reduce single-use plastic consumption, particularly items likely to reach the ocean
Participate in coastal and beach clean-up events
Support organisations working on ocean plastic pollution and seabird welfare
Advocate for extended producer responsibility for plastic packaging
Avoid balloon releases — balloons deflate and fall into the sea where they cause seabird harm
