PLASTIC FOUND AT THE BOTTOM OF THE SEA

When Victor Vescovo’s deep sea submarine hit the floor of the Mariana Trench, it sent the sediment swirling.

“At bottom,” the Texas businessman-turned-extreme-explorer said into his headset. “Repeat: At bottom.” In a control room some 35,853 feet above, Vescovo’s dive team clapped and cheered. Congratulations were in order: they had just set a record. The American had descended deeper into the ocean than any person before him. An upturned Mount Everest would still be a mile from where his vessel then sat.

Vescovo spent four hours down at the bottom of the trench he told The Washington Post. The crevice in the western Pacific Ocean is one of the most remote places on Earth, where the sun doesn’t shine and the pressure is crushing. He was literally charting new territory, mapping his route for future researchers, when he noticed something familiar among the otherworldly terrain.

Vescovo spent four hours down there, he told The Washington Post. The crevice in the western Pacific Ocean is one of the most remote places on Earth, where the sun doesn’t shine and the pressure is crushing. He was literally charting new territory, mapping his route for future researchers, when he noticed something familiar among the otherworldly terrain.

It was some sort of plastic waste. Initial reports indicated that it was a bag, or maybe a candy wrapper. But those theories weren’t quite right, officials now say. Whether it was flotsam or jetsam is secondary. The find is, no matter what, the imprint of a species that has polluted the planet like none other.

Translucent creatures undulated around his craft, Vescovo said. He was struck at how alive his surroundings were.  “There was definitely life at the very bottom of the ocean,” he said. “It was not dead by any means. … I felt very excited, privileged to get to see it, but also very much at peace because it really is a quiet, peaceful, place.”

The expedition identified at least three new species of marine animals, its scientists said, including a kind of amphipod, a crustacean that resembles a shrimp. Yet, even as the team discovered new life, it could not escape signs of the man-made havoc that will likely kill off many more species faster than humans can discover them. He was referring to plastic refuse.

Vescovo said. “With over seven billion people on the Earth, the oceans are going to be impacted negatively by mankind, but I hope we can at least minimize it in the future.”

Reports of Vescovo’s findings prompted Chelsea Clinton, vice chair of the Clinton Foundation, which advocates for ocean cleanup projects, to pose a dire question on Twitter: “A sub dive 7 miles deep in the ocean at the Mariana Trench finds possible new species of shrimp and a plastic bag. How long will the former survive if there’s more of the latter?”

 An alarming, landmark United Nations report released in May 2019 illustrated a version of Clinton’s point: as the population of humans has rapidly increased, the population of everything else has steadily declined.

“How long can the two trend lines continue to head in opposite directions?” asked the author Elizabeth Kolbert in an essay for the New Yorker. “This is the key question raised by the report, and it may turn out to be the key question of the century.”

There was definitely life at the very bottom of the ocean,” he said. “It was not dead by any means. I felt very excited, privileged to get to see it, but also very much at peace because it really is a quiet, peaceful, place.”  I should point out that the same can be said about a garbage dump on the surface of the Earth.

“I was disappointed to see human contamination in the deepest point in the ocean,” Vescovo said. “With over seven billion people on the Earth, the oceans are going to be impacted negatively by mankind, but I hope we can at least minimize it in the future.”

A summary of the report warned that, “Nature is declining globally at rates unprecedented in human history – and the rate of species extinctions is accelerating.”

The report’s nearly 150 authors found that human actions have “severely altered” 66 percent of the world’s marine environments, threatening a third of all marine mammals with extinction.

The lone piece of waste Vescovo sighted isn’t going to single-handedly kill off an entire species. But its very presence is yet another reminder of humanity’s far-reaching impact. In a study published earlier this year, British researchers analyzed amphipods – similar to the ones Vescovo identified – captured in six of the ocean’s deepest trenches, including Mariana. They found plastic particles in more than 70 percent of the creatures they tested and in all of the amphipods from the Mariana Trench.

The study’s implications are striking: before we even discover some of these underwater species, they’re already all too familiar with one of man’s most prolific creations. Before their even born,  they have plastic cursing through their bodies.

“We can now say with confidence that plastic is everywhere,” the study’s lead author Alan Jamieson told the National Geographic magazine.

The Deep-sea Debris Database, maintained by the Japan Agency for Marine-Earth Science and Technology, allows for an up-close examination of some of this trash, including a few pieces found on dives into the Mariana Trench. Vescovo’s find would be the deepest piece of debris in the database.

Vescovo’s expedition was the third time a team had dived to the bottom of Challenger Deep. Before him, the filmmaker James Cameron made the trek in 2012. U.S. Navy Lt. Don Walsh and the Swiss scientist Jacques Piccard were the first to do it in 1960. But neither team dove as deep as Vescovo, who also became the first person to repeat the feat, over a week. The journeys were part of his Five Deeps Expedition, which was being filmed for the Discovery Channel.

The submarine technology has improved so much, Vescovo said, that he sees this as the beginning of a golden age of underwater exploration. His vessel, made by a company called Triton, recently gained commercial certification, which means more could soon be made.

“Such a thing has never existed before,” Vescovo said. “We can make more of them, to really open up the 90 percent of the ocean that has heretofore remained unexplored.”

If plastic keeps being dumped into our oceans, these subs may have to have a snow plow attached to them so that they can move the plastic out of their way as they descend to the bottom of the oceans.
