“But that’s only a concern due to the sheer number of jets in the air.”
You can say that again! Just going to an airport and seeing the lists of incoming and departing flights on a daily basis, hour after hour - and then multiplying those by every major airport in the U.S., the number of planes day and night 24/7 in the air over just this country (not to mention the world) is now absolutely mindboggling! Since we can’t control the amount of air traffic (the world’s changing all the time with more people and technological advancement), wouldn’t we be much wiser to combine our conspiracy theories with some research on ways to clean the air in our own personal living space? - We got a large air purifier at Lowe’s and run it in our house night and day. I put clay pots of pollution and UV absorbing clay next to the computer just in case. I don’t spray chemicals to kill bugs but use sifted diatomaceous earth under the baseboards in the house instead (it works great, but just keep it out of your eyes, it’s prehistoric bug skeletons and is sharp, can scratch the delicate eye tissue, use natural cleaners everywhere you can, wear a face mask when working outside, natural fertilizers in garden - things like that, no perfumes and colognes, mild soaps, filter the chlorine and fluoride out of your water, etc., etc.)
A person can beat their heads against the wall and worry about any and everything until they lose their marbles; and, of course, it can be a fun pursuit of happiness to do so as long as they don’t become so completely obsessed about it that it’s all they think about or do around the clock to the detriment of themselves and their families far beyond what a bit of pollution might do.
I learned a long time ago that something can look an awful lot like it’s 99.9% one way, when in reality it’s something else entirely.
I live about 70 miles out from Detroit. Some days I can see a dozen jets at one time plus contrails from others. Mostly I don’t like looking at contrails because they screw up an otherwise good photograph.
I’m kind of a conservative environmentalist myself. No pesticides here. I let the snakes, frogs, toads, bats and birds keep most insects at managable levels. I’ve found that a little boric acid in sugar water keeps the ants in check. My big problem is japanese beetles but I like picking those by hand and feeding them to the bluegills along the shoreline.
