Episode 26: Tire Pollution Is Not Just a Salmon Problem + The Takes We’re Taking Back

Tire Pollution - David & Wes look at tire pollution and why the harms may be broader than most people realize. What started as a story about 6PPD-Q washing into streams and devastating coho salmon is now raising new questions about human health, including a recent study linking tire-related pollution to Alzheimer’s-related pathways. They talk through what we know, what we still do not know, and why tire wear should be part of the transportation pollution conversation, even in a world with more electric or autonomous vehicles.
