Plastic Bag Found at the Bottom of World's Deepest Ocean Trench (nationalgeographic.com)

The Mariana Trench -- the deepest point in the ocean -- extends 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. From a report: 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.

I would expect things to COLLECT in the deepest portions. As current moves things around, they will eventually tend to settle in the deepest portions as it's much much likely that currents will sweep debris up and out of these places.

Humans are very prone to magical thinking about even the most practical matters. For example, a small but meaningful fraction of the world population thinks that their fossil CO2 emissions magically don't contribute to climate change.
