PFAS Contamination and Wildlife Welfare

Per- and polyfluoroalkyl substances (PFAS) are persistent chemicals contaminating wildlife globally, causing reproductive, immune and developmental harm.

Key Facts

PFAS are a group of over 4,700 synthetic chemicals used in non-stick coatings, firefighting foam, food packaging and industrial processes
They are called 'forever chemicals' because they do not break down in the environment or animal bodies
PFAS have been detected in polar bears in the Arctic, dolphins in the Atlantic, eagles in North America and fish worldwide
Reproductive failure, immune suppression and developmental abnormalities have been documented in PFAS-exposed wildlife
Bald eagles in Great Lakes regions showed PFAS contamination linked to eggshell thinning and reduced reproductive success
Many countries are beginning to restrict PFAS production and use but existing contamination persists for decades

Welfare Considerations

PFAS contamination represents a global, multi-generational welfare harm to wildlife. Unlike point-source pollution that dissipates, PFAS accumulate in food chains and persist in animal bodies indefinitely - a polar bear born today will accumulate PFAS throughout its lifetime with no mechanism for elimination. Immune suppression increases susceptibility to disease, causing welfare harms that are invisible without detailed health assessment. Reproductive failure reduces fitness but also represents a form of welfare harm - animals investing energy in reproductive attempts that fail. The irreversibility and global distribution of PFAS contamination make it one of the most pernicious ongoing welfare harms to wildlife, requiring both source elimination and remediation research.

What You Can Do

Avoid products containing PFAS where alternatives exist - non-stick cookware, stain-resistant fabrics, food packaging
Support regulatory campaigns to restrict PFAS production and use internationally
Advocate for PFAS cleanup at contaminated sites including former military air bases
Support research into PFAS wildlife health impacts to strengthen the evidence base for regulatory action
