What is the danger of pollution of the Mariana Trench?

As you know, the Mariana Trench is the deepesta place on the planet located in the western part of the Pacific Ocean. It is in this place that the so-called Challenger Abyss is located, the depth of which is a record 10,994 meters below sea level. In order to acquaint his followers with hitherto unknown depths and their inhabitants, researcher Victor Veskovo decided to create a map of the relief of the World Ocean, and during his record dive into the Mariana Trench, he found something that caused concern among environmentalists: at the bottom of the Mariana Trench trash was found.

The deepest point of the Mariana Trench is considered to be the Challenger Abyss, which the famous film director James Cameron alone managed to reach in 2012

What is at the bottom of the Mariana Trench?

When back in 1875 the British expeditionfor the first time able to discover a giant trench using a probe rope, the research team was able to determine that the depression they found was about 5 miles deep. After almost 100 years, another British expedition used the sonar technology, updating the depth data to a mark of 7 miles. Since the first surface research attempts were made to map the Mariana Trench, few have attempted to physically visit the giant trench and explore its depths. Only in the 1960s were researchers able to reach the depths for the first time in person. In 2012, director of the Titanic and Avatar, James Cameron, visited the Challenger Abyss, setting a world record for a single dive at 10,908 meters. After 7 years, the record was broken by the businessman Viktor Veskovo already mentioned above, who went down to a depth of 10,928 meters.

The immersion of the researcher took him to 10 928meters deep into the deepest trench on Earth. Each trip on his underwater vehicle was limited to about 12 hours, which necessitated a series of dives into the Mariana Trench, in order to study the ocean floor in detail. Despite the fact that the main purpose of Viktor Veskovo’s dives is considered scientific, the researcher himself claims that it was at depth that he wanted to find the limit of creative curiosity laid down by man by nature. Well, it sounds poetical.

Being at the very bottom of the trench, Veskovo discoveredat least three new species of marine life, but what was more striking was the presence of a plastic bag and candy wrappers from sweets floating in the depths. Such an unusual finding may indicate the extent of environmental pollution, which is about to take on a worldwide scale.

In addition to garbage, at the bottom of the Mariana Trenchdiscover truly unique living creatures. So, the xenophiophores discovered several years ago made a real sensation in the scientific community because these living organisms are one big 10-centimeter cell, which has developed incredible resistance to high pressure and complete darkness, which reigns at a 10-kilometer depth.

In addition to unicellular organisms, at the bottomThe Mariana Trench is inhabited by a huge variety of mollusks, which in some unknown way managed to keep their shell even at a pressure of a thousand atmospheres. In addition to the presence of this unique property, deep-sea inhabitants boast the ability to convert the fatal hydrogen sulfide for them into an absolutely safe protein that allows mollusks to survive in the most extreme conditions.

It is well known that ocean pollution does not affectonly on the lives of marine life and coral reefs, casting doubt on the survival of even resilient ecosystems, it affects everyone. Thus, pollution of ocean waters can provoke the penetration of toxins into seafood, significantly reduce the economic profit from beach holidays and tourism, and also adversely affect the development of coastal countries. The find of Victor Veskovo in this case only confirms the existence of a problem that is becoming global everywhere.
