Having lived next to a semi-main street through a smallish California coastal city without much rain it is pretty eye opening how much black dirt and junk just coat everything next to the road.

Walk down the street and touch a bush or any plant leaf and get a nice black hand in the process. The plants are covered, parked cars get covered and the inside of my apartment was covered.

It wasn’t until I moved out that I saw the extent of the problem. I only lived there a few years but every surface of my apartment had a coating of the same black dust. I’m now very worried my short time there considerably affected my health.
