    Funnily enough, this is half correct as countries do put stuff that ruin the climate in the sky.

    It’s just called greenhouse gasses though.

      Actually… There is speculation whether the excessive numbers of satellites (e.g. the Starlink satellites) going into orbit currently will disturb the ozone layer upon re-entry in a couple of years.

        I think we’re beyond speculation. It seems pretty solid to me that burning metals on re-entry will release harmful chemicals. Why it hadn’t been proposed before, I suppose just because it wasn’t happening on such a gargantuan scale. Fuck Lonnie.

          I doubt the mass of satellites is in any way comparable to the normal influx of meteors.

          > An estimated 25 million meteoroids, micrometeoroids and other space debris enter Earth’s atmosphere each day,[9] which results in an estimated 15,000 tonnes of that material entering the atmosphere each year.

          So 250 vs 15,000 tons per year, round up and it’s 2%. Another estimate said 40,000 tons. Satellites are definitely not a significant influence.
