How the Planet-Altering Disaster of "Forever Chemicals" Was Kept Secret

3M knowingly concealed decades-long evidence that "forever chemicals" (PFAS) were toxic and accumulating in human bodies and the environment, despite discovering this as early as the 1970s. These synthetic chemicals, used in everyday products like nonstick cookware and food packaging, don't break down in the body and cause serious health effects including cancer, immune system damage, and hormonal disruption. The company's decades-long secrecy allowed the chemicals to spread globally, turning what could have been a contained problem into a planetary-scale disaster.
