This 18 February 2020 video says about itself:
The Mariana Trench is the deepest point on Earth, void of light with the pressure of 48 jumbo jets. Yet life finds a way to survive. Very weird life. Like crustaceans with aluminium shields or the blind, translucent snailfish, the deadliest predator in the trench and of course the sea pig, a type of sea cucumber that crawls with its tentacles. But the most surprising thing in the deep ocean is plastic… that’s right even the deepest part of the ocean can’t escape human pollution.
