Pollution affects our brains!
Glad some neuroscientists are finally taking this more seriously!

Your Brain Breathes Too by Knowing Neurons

While air pollution is generally thought of as a modern problem, humans have evolved to handle polluted air from sources such as forest fires and volcanic eruptions.  Coughing removes large particles from the lung, while macrophages, a type of immune cell, are responsible for engulfing and degrading small particles.  However, some particles are so small that they can penetrate the lung wall, and gaseous…

Soot (and ‘by’products) from burning wood, diesel, coal or other fossil fuels are bad enough for the planet, but did you know that those particles attract harmful chemicals (secondary organic molecules) from the air so when we breathe them in, their adverse health effects can be multiplied?
