Hey, no problem, right ?
"This finding supports growing concerns that space traffic may pollute the upper atmosphere in ways not yet fully understood "
The Human species has been doing things it hasn't fully understood since Day 1 (your choice, I'm not picky on that score).
So, this is another thing we don't fully understand. That is not going to keep China and India from going full-ahead with their own space programs, because honestly, you are not a World Power if you don't have "eyes in the sky", right ?
And if a few hundred million peons need to suffer forthat, who cares ? We're too many on Earth already, right? So, gien that Natural Selection has failed to curb the ever-increasing dominance of Man over Earth, Artificial Selection will have to replace it.
And, given how little practically every country's government is allocating budget to the education sector (vs, for example, the military sector), it's fairly obvious that "the elite" (aka : those who have "connections") are not interested in educating the masses beyond what they need to have a compliant base who will blindingly obey whatever edict "the elite" decide to publish.
As in, COVID. Enough said.
