Plastic pollution causes welfare harm to individual wild animals through entanglement, ingestion, and chemical contamination across terrestrial and aquatic environments.
Wildlife entangled in plastic rings, packaging, and discarded fishing gear suffers from restricted movement, injuries, and eventual starvation or drowning. Animals that ingest plastic feel satiated without nutritional benefit, leading to progressive starvation. The welfare harm of plastic pollution is distributed across billions of individual animals. Reducing plastic at source and removing plastic from the environment directly reduces individual animal suffering.
