How 3M covered up the dangers of 'forever chemicals' for decades

On this edition of Your Call’s One Planet Series, ProPublica investigative journalist Sharon Lerner discusses her latest investigation about how 3M kept the dangers of PFAS from the public and allowed forever chemicals to seep into our bodies and our environment.

Recent studies have linked PFAS to an increased risk of some cancers, developmental effects in children, reduced immune function, interference with hormones and other health harms.
