@helenczerski I assume you’ve heard of this project - https://metals.co/nori/ and how they’ve partnered with a tiny ocean nation that was basically destroyed from mining and left with nothing.
Now they want to scrap the ocean floor for nodules that have rare metals.
It’s a bad idea and with all luck will fail.
I seem to remember a recent study showed that the nodules are active components in the ocean for oxygen creation, but can’t find a link to the study at the moment.
