More damning information about air pollution...

“I have no hesitation whatsoever to say that air pollution causes dementia,” said one leading researcher."

"Researchers now better understand what happens in the brain when you breathe polluted air—and how that can lead to neurodegeneration years later. When you inhale pollutants, the smallest particles, emitted by cars, power plants, and other places where fuel is burned, lodge in your lungs’ sensitive tissue or else pass into your blood stream. In those places they trigger an immune response that seeks to trap, contain, and remove the invading particles. In time that response generalizes to what we call “systemic inflammation,” or an over-active, overly excited immune response across the body."
