Defining environmental pollution and its role in longevity

Asked to define environmental pollution, Peter Attia is precise: it's not anything manmade or detectable, but specifically something that negatively affects a living system. He scopes the episode to four categories — air, noise, light, and electromagnetic fields — explicitly noting that microplastics, PFAS, and phthalates were covered in a prior AMA. The longevity connection is made through diseases we care about: cardiovascular disease, respiratory disease, cancer, sleep disruption, and cognitive effects. Peter makes a key conceptual move here — distinguishing between obvious catastrophic events (wildfires, Chernobyl) and the much harder question of what chronic sub-threshold exposures do over years and decades. He introduces the concept of the 'area under the curve' of cumulative exposure as the framework for thinking about chronic environmental risk.
Environmental pollution is the introduction of harmful substances or forms of energy into the environment. The key word is 'harmful' — not merely unnatural or detectable. For this episode that means air quality, noise, artificial light, and electromagnetic fields, not water or soil (covered previously).
Peter Attia references a prior AMA episode on chemical pollutants — microplastics, PFAS, and phthalates — and explicitly excludes those from this episode's scope, focusing instead on the physical environment.
