Dear Peacefullskies,
Welcome to pprune.
Thanks for the interesting article from USA Today.
It does, however, seem to defeat your argument! With maybe 6-8 flights a day - as reported - from most airports, that's not a lot of noise!
The American system of local airports is the envy of the world.
The vast open spaces are also something to be envied too - I know, I have flown an ultralight across the USA.
I really think, in Oregon, you can find some places where outside noise will be unobstrusive. Getting peace and quiet - of any kind - in Los Angeles or NYC is another matter.
Very best wishes with your interests in nature, you'll find many pilots share them too.
And you will find many airfields are, in fact, wildlife sanctuaries. Something they wouldn't be if concreted over with housing estates as wished for by one person quoted in the USA Today article.
