Sea Turtle Welfare and Beach Nesting Threats

Sea turtles face welfare threats across their entire life cycle from plastic ingestion and fishing bycatch at sea, to light pollution and development disrupting beach nesting.

Key Facts

Seven sea turtle species exist globally, all listed as threatened or endangered
Beach light pollution disorients hatchlings, causing them to head inland instead of toward the sea
Plastic bag ingestion causes fatal gut blockages - turtles mistake them for jellyfish
Fishing longlines and trawls kill an estimated 200,000 sea turtles annually
Turtle nesting beach temperatures determine offspring sex - warming creates female-biased populations
Fibropapillomatosis, a tumour disease, is increasing in sea turtle populations globally

Welfare Considerations

Sea turtle welfare involves multiple overlapping harms across a long lifespan. Plastic ingestion causes slow starvation as the gut becomes blocked with indigestible material. Bycatch victims experience drowning or severe hook injuries. Disoriented hatchlings that walk inland die of dehydration and exhaustion. Females with fibropapillomatosis carry large tumours that impair movement and feeding. The temperature-induced sex imbalance may ultimately threaten population viability. Beach lighting reform, bycatch reduction, and plastic reduction are the most direct welfare interventions.

What You Can Do

Turn off beach-facing lights during nesting season (May-October in tropical zones)
Choose certified sustainable seafood to reduce sea turtle bycatch
Remove plastic litter from beaches whenever you encounter it
Support Sea Turtle Conservancy and Oceana sea turtle protection campaigns
Never purchase tortoiseshell products which contribute to illegal turtle trade
