The Mariana Trenchthe deepest point in the oceanextends nearly 36,000 feet down in a remote part of the Pacific Ocean. But if you thought the trench could escape the global onslaught of plastics pollution, you would be wrong.
A recent study revealed that a plastic bag, like the kind given away at grocery stores, is now the deepest known piece of plastic trash, found at a depth of 36,000 feet inside the Mariana Trench. Scientists found it by looking through the Deep-Sea Debris Database, a collection of photos and videos taken from 5,010 dives over the past 30 years that was recently made public.
EDIT
Last February, a separate study showed that the Mariana Trench has higher levels of overall pollution in certain regions than some of the most polluted rivers in China. The study's authors theorized that the chemical pollutants in the trench may have come in part from the breakdown of plastic in the water column.
Plastic has recently become a greater focus of the environmental movement, being featured prominently this past Earth Day, for example. While plastic can enter the ocean directly, such as trash blown from a beach or discarded from ships, a study published in 2017 found that most of it is flowing into the sea from 10 rivers that run through heavily

(2,050 posts)Since day one all waste oil generated by ships was pumped over the side, this has luckily been changed since 1990 but it's exactly what they did with it back then.
Then with all the natural seeps and oil from sunken ships it becomes part of the water column, untold millions of gallons.
And we wonder why the seas are polluted.
