Look at this one-way underwater trash bag
I subscribe to this channel but I can't say I've seen one of the videos lately until today. And in viewing this video of this diver recovering a lost drone underwater, I was more interested in the one-way underwater trash bag he was carrying to collect random trash while on his hunt. Pretty neat that he's doing TWO good things here.
Diving into a septic tank
Or as the video description states: "Liquid manure". Can anybody fill me in on what is going on here? Are they unclogging the system?
Turning Oil Rigs Into Reefs
This video reminds me of what the NYC MTA did with old Redbird Subway cars by dumping them into the ocean to create artificial reefs. This type of artificial reef, obviously, is made from defunct oil rigs in the Pacific Ocean, just off the coast of Southern California. It's amazing to see these giant structures turned into living spaces for aquatic life. The scale of these structures is insane, especially when you see in the video how small a diver is compared to just one single beam of support for these ocean structures. I've always wondered how these rigs are anchored to the ocean floor (is it just not as deep as I thought?) or are they just really, really, really insanely tall? Also, how do they not degrade with the salt water to the point where they just collapse slowly? So many questions...
But look at those reefs! Teeming with life and other sea creatures all using the base of the rig as a life support system. Pretty cool. I'd love to dive here too!
