Honestly I have no idea why people think we're going to find a safe and equally effective alternative. Most of the PFAS in use are powerful surfactants that change the surface tension of water, break up the lipids in cell membranes, and otherwise interfere with almost all the chemical processes that make life life. Everything from cell walls to capillary action are directly effected by these molecules. The same features that cause them to bioaccumulate so well give them their incredible industrial properties.
