Marine Debris Impact on Sea Turtles and Marine Wildlife

Plastic pollution and marine debris cause suffering and death in sea turtles, seabirds, marine mammals, and fish through ingestion, entanglement, and habitat degradation.

Key Facts

Sea turtles mistake plastic bags for jellyfish, a primary food source; ingested plastic causes intestinal blockages and starvation
Ghost fishing gear from lost or abandoned nets continues catching marine wildlife for decades
An estimated 100,000 marine mammals and 1 million seabirds die from plastic pollution annually
Microplastics have been found in the digestive systems of virtually every marine species studied
Beach cleanups remove debris but the primary solution requires reducing plastic production and waste

Welfare Considerations

Marine debris causes suffering in ways that span from acute to chronic. Entanglement in fishing gear leads to drowning, lacerations, exhaustion, and infection. Ingested plastic causes blockages, reduced feeding, starvation, and toxin exposure. For sea turtles with decades-long lifespans, chronic sub-lethal impacts accumulate over time. The scale is planetary, with no ocean habitat remaining free from plastic pollution. Individual consumption reduction, policy-level plastic reduction, and support for marine conservation organizations all contribute to addressing this welfare catastrophe.

What You Can Do

Reduce single-use plastic consumption systematically, focusing on items with poor waste management infrastructure
Participate in or organize beach and waterway cleanups
Advocate for extended producer responsibility legislation for plastic packaging
Support marine conservation organizations working on ghost gear removal and plastic policy
Choose seafood from fisheries with low gear loss rates and active debris management programs
