Three business executives vacationing (?) in the Bahamas came across part of a SpaceX Falcon 9 fairing that washed ashore. They shared their find with Elon Musk via Twitter.
We found part of your @SpaceX washed ashore in the Bahamas.
Musk replied:
Cool, thanks for letting us know. This is helpful for figuring out fairing reusability.
The men said they will be returning the GoPro camera and sim cards mounted inside the fairing back to SpaceX. No word on the disposition of the fairing itself.
Once or twice is, as Musk says, "cool", but there is an escalation of launches, and recovery of various bits will never be 100%.
Overall, as world-wide launch cadences increase, will space junk become as common on the high seas as it is in orbit?
Question: Is there a mitigation plan for future ocean space junk in place, or one being considered or at least discussed?
The question What makes 21st century fairings so valuable that they'd potentially be recovered and re-used? begs the question "should launch providers have to pay a "bottle deposit" to encourage them, or subcontractors to collect and return the stuff that washes up on shore?

From this comment is linked Found on the beach on Cape Hatteras, NC. Looks to me like part of a spacecraft, or perhaps a high-tech yacht or racing boat. which links to this collection of photos: https://i.sstatic.net/Fq5Rp.jpg
