Sea bed mining is an incoming disaster. It's super tempting for mining companies because the sea floor is riddled with surface level minerals, already in convenient nodules that could be picked up. Look at videos of prospective locations and you'll understand. Miles and miles of flat sea bed with spherical nodules of rare metals just sitting there, practically begging to be picked up. Not hard to see why that would make magnates start salivating.
It was first assumed that any disturbtion to the sea floor would be minimal and it would recover quickly. So we did a study in the 70's or 80's where we mined a small area. To this day, that area hasn't recovered at all. Images from when they finished and now are identical. The sea floor does NOT recover. At least not on a human timescale.
Unfortunately, the reaction to this study showing that any mining would cause irreversible damage was a collective shrug from mining companies as they're all moving ahead with their plans anyways. They already made their decision, and there is nowhere near enough opposition to stop them.
