If you want to get really blackpilled look up how the aluminium from starlink reentry degrades the ozone layer

These satellites are designed to last about five years. A 550-pound satellite will release about 66 pounds of aluminum oxide nanoparticles during reentry. Starlink’s satellites have grown heavier over time, with the latest version weighing in at about 2,760 pounds.

The aluminum will mostly be released between 30 and 50 miles above the Earth’s surface but will then drift down to the ozone layer, which would take about 30 years. We’re already seeing these effects – satellites burning up in 2022 caused a 29.5% increase of aluminum in the atmosphere above the natural level – but the researchers said it will only get worse.

mmm, gross.

30 kilograms of Aluminium-oxide per satellite btw. And its multiple per day. The kind of mass and local concentration makes it different from the cosmic Dust the earth is bombarded by 24/7.
