That's fine about Reagan. As I stated, I don't remember.
But - with all due respect, Google the simple question "Is pollen considered pollution?", and see what you get.
Pollen IS part of pollution, it's just not man-made.
And it's WAY more than "bothersome" for a lot of people.
Thanks for the additional comments.
I don't consider something that is biodegradable to be pollution. You and probably a lot of other people do.
Trees make a real mess of things sometimes. They also give off pollen which can bother people. As a kid I suffered from extreme asthma. That's life. I still don't consider something that will be part of the earth in a few months, and help to sustain other life, to be polution. Hey, that's just my take on it.
You take care.
