Opinion piece by Sierra Solter, “a plasma physicist, engineer, and inventor who studies the intersection of heliophysics and aerospace”. Relevant quote:
Upon investigating just how much dust in the form of satellite and rocket debris the space industry has dumped into the ionosphere during re-entry, I was alarmed to find that it is currently multiple Eiffel Tower’s worth of metallic ash. I wouldn’t have even been able to calculate that at all without a scientist’s personally run website. Our ozone is mere pennies thick, and soon we will be putting at least an Eiffel Tower’s worth of metallic ash a year directly into the ionosphere. And all of that will stay there, indefinitely.
How could we possibly think that burning trash in our atmosphere 24/7 is going to be fine?

A dead spacecraft the size of a truck ignites with plasma and pulverizes into dust and litter as it rips through the ionosphere and atmosphere.
There are currently nearly 10,000 active satellites and companies are working as fast as possible to get tens of thousands more into orbit – for a projected 1m in the next three to four decades.
Those satellites power hyper-connected internet services and may turn some billionaires into trillionaires – at the cost of shrouding the planet with toxic trash.

Low Earth orbit is being promoted as a “destination and economy” for satellites and even low-gravity space hotels (which seem to be perpetually “coming soon” and then canceled).
