Weekend wrapup of earlier trivia question:What happens to worn off tire tread?
Part of it is washed into watersheds as was indicated.
The hydrocarbon rubber is eventually munched up and oxidized by
vast numbers of bacteria, many of them waiting patiently by the side
of the road for bite size morsels to drop their direction.
These little buddies save us from a lot of our sloppiness.
Now, if we could genetically engineer flying bacteria who devour smog.....
