Marine Plastic Pollution and Marine Animal Welfare

Marine plastic pollution causes injury and death to hundreds of thousands of marine animals annually. The welfare consequences of entanglement and ingestion affect species from seabirds to whales.

Key Facts

An estimated 8 million tonnes of plastic enters the ocean each year, with accumulation in gyres covering vast areas
Over 700 marine species including sea turtles, whales, seabirds, and fish interact with marine plastic
Entanglement in plastic debris causes drowning, starvation, and amputations in marine mammals and seabirds
Albatross parents feed plastic particles to chicks which die of starvation with stomachs full of plastic
Ghost fishing from abandoned nets and gear continues to entangle and kill marine animals for years
Microplastics have been found in the digestive systems of fish, crustaceans, and marine mammals globally
The Great Pacific Garbage Patch covers an area larger than Texas with an estimated 80,000 tonnes of plastic

Welfare Considerations

Marine plastic pollution causes acute and prolonged animal suffering across hundreds of species. Entanglement in ghost fishing gear causes slow death by drowning or strangulation over hours or days. Tight loops of plastic around seals and sea lions cause progressive strangulation as animals grow, embedding plastic in tissue with severe infection and amputations. Ingested plastics block digestive systems causing starvation despite continued feeding behaviour. Albatross chicks dying with plastic-filled stomachs experience prolonged starvation. The scale of welfare harm from marine plastic affects millions of individuals annually across trophic levels. Addressing plastic pollution requires systemic changes to production and waste management that benefit animal welfare alongside ecosystem health.

What You Can Do

Reduce single-use plastic consumption particularly items most likely to enter marine environments
Participate in or organise beach and waterway cleanup activities removing plastic before it reaches the ocean
Support extended producer responsibility legislation making plastic manufacturers responsible for waste
Advocate for binding international plastic pollution treaties with ocean protection requirements
Donate to marine animal rescue organisations treating entangled and plastic-injured animals
Support research into plastic pollution tracking and marine animal welfare impacts
