Ever since our early ancestors gathered around their first fire, humans have been releasing fine particulates
into the air. Only recently have scientists discovered the bad news; fine particulates are so small that they
can easily be inhaled into the deepest reaches of our lungs, causing serious breathing disorders. Fine
particulates are also a visual blight, capable of reducing visibility so much that beautiful views are blotted
out, and road and air travel is made difficult. But if humans have managed to live with fine particulates for
thousands of years, why all the fuss now?
