A recent survey by the UK’s Marine Conservation Society found that many people are unaware of “forever chemicals,” or PFAS. Most respondents did not know that these chemicals can contaminate drinking water and are often found in everyday products. These substances pose a threat to marine life and can enter oceans through polluted water systems. The survey revealed public concern about PFAS’s impact on health and the environment, leading to calls for stricter regulations to ban their use where alternatives exist. Protecting marine ecosystems from these harmful chemicals is essential for all divers who enjoy the ocean.
