This podcast episode explores the pervasive presence and potential health risks of PFAS (per- and polyfluoroalkyl substances), also known as forever chemicals. PFAS are found in various products and have been detected in rainwater worldwide, at levels exceeding safety standards. These chemicals are extremely stable, making them resistant to degradation in the environment, and they have been linked to endocrine disruption and a range of health issues. The episode also addresses the need to reduce our dependency on fossil fuels and the challenges involved in decarbonizing the chemical industry. Overall, the podcast highlights the urgency of addressing the chemical crisis and the importance of personal and collective action in reducing exposure to harmful substances.
