The ocean is home to all sorts of mysterious and terrifying things, but there’s one discovery in particular that should be used as a warning to pretty much every single human on Earth.

The disturbing find was made at one of the deepest parts of the ocean, known as the Mariana Trench.

It’s the deepest spot on Earth, measuring some 11km (seven miles) down and sitting far below the surface of the water somewhere between Hawaii and the Philippines near the small island of Guam.

Scientists have claimed that getting to the lowest point of the sea is just as difficult as getting into outer space.

Victor Vescovo was one of a select few to make the journey down to the deepest point of Mariana Trench in April 2019.

During his mission, Vescovo reached a new record depth of 10.9km in a Triton 36000/2 submarine, which is built to withstand the extreme pressure.

Given how deep the trench is, it wouldn’t be all that surprising to come across something unexpected.

However, considering it’s in the ocean, you’d expect that discovery to involve some sort of sea creature, or weird plant.

Vescovo did admittedly come across a bit of that in the form of a previously unknown crustacean species, along with brightly coloured outcrops and a pink snailfish, but he also found something that definitely shouldn’t have been there.

In a horrifying discovery, Vescovo managed to find lolly wrappers and, more specifically, a plastic shopping bag.

Again, just to reiterate, this trash was found at the deepest spot on Earth.

Eric Galbraith, an ocean biochemist at the Catalan Institution for Research and Advanced Studies in Barcelona, commented on the disturbing find as he said: “We always had this sense that there was a part of the planet that was beyond, that was untouched by human action. That used to be true. And now it’s no longer true.”

A similar depressing find came when Dr Deo Onda, a microbial oceanologist from the University of the Philippines Marine Science Institute, dove into the Emden Deep, part of the Philippines Trench.

“The Philippine Trench is already so deep, but human pollution was still able to reach it. What more for shallower environments like coral reefs and seagrass beds?” Onda told The Inquirer.

“[If we don’t do anything], I wouldn’t be surprised if I would get confused if I was in the Philippine Trench or in Manila Bay.”

In 2018, researchers from the Institute of Deep Sea Science and Engineering in China determined that man-made plastics had ‘contaminated the most remote and deepest places on the planet’.
