Found this when snorkling in Greece about 17 years ago when i was just a kid. Always wondered what it was... Anyone an idea? Almost certainly made of metal and i think it is hollow on the inside. (lemmy.world)

I can't confirm if that's true, but that is actually oddly interesting. Maybe the downvotes because... It sounds so weird?: adding trash to water is bad, but removing trash can also be bad?

It is really a headscratcher for me too, would like to read some info about it if you can share some sources?

There's just a different "quality" of trash. Something deeply embedded in the ecosystem will become part of it. If you plug a bottle or large piece of metal from the floor you will destroy some form of habitat. Floating plastic has to go of course, as well as strings or nets.
