The risk of contamination of the Mariana Trench?
As is known, the Mariana Trench - the deepest place on the planet, located in the western Pacific Ocean. It is in this place is so-called Challenger Deep, the depth of which is a record 10994 meters below sea level. In order to acquaint his followers to hitherto unexplored depths and their inhabitants, researcher Victor Vescovo decided to create a map of the world ocean topography, and during his record dive to the Mariana Trench, he found something that caused concern among environmentalists: at the bottom of the Mariana Trench debris was found.

What is at the bottom of the Mariana Trench?
When back in 1875 the first British expedition was able to find a huge trench, using a probe with a rope, the research team was able to determine that the cavity found by them was about 5 miles deep. After nearly 100 years, another British expedition used sonar technology to update the data of the depth to the level of 7 miles. Since the first research attempt to map the surface of the Mariana Trench, only a few have attempted to physically visit a giant trench and explore its depths have been taken. Only in the 1960s, researchers have been able for the first time to reach the depths of the person. In 2012, the director of "Titanic" and "Avatar", James Cameron visited the Challenger Deep, set a world record for a single dive to 10,908 meters. 7 years later, the record was beaten already mentioned above businessman Victor Vescovo, descended to a depth of 10,928 meters.

researcher dive claimed it to 10,928 meters into the deepest trench on Earth. Every trip to his underwater vehicle is limited to about 12 hours, which made it necessary to commission a series of dives in the Mariana Trench, the purpose of a detailed study of the ocean floor. Despite the fact that the main purpose of diving Victor Vescovo considered science, the researcher argues that at a depth he wanted to find the limit of artistic curiosity, inherent nature of man. Well, it sounds poetic.

Being at the bottom of the trench, Vescovo found at least three new species of marine life, but what was more striking is the presence of plastic bags and wrappers from sweets, floating in the depths. Such an unusual finding may be indicative of the extent of environmental pollution, which is about to adopt a global scale.
In addition to the trash at the bottom of the Mariana Trench can be detected and truly unique living beings. For example, open a few years ago xenophyophore created a furor in the scientific community due to the fact that these organisms represent a single large 10-centimeter cell to develop the incredible resistance to high pressure and total darkness which reigns in the 10-kilometer depth.

Apart from single-celled organisms at the bottom of the Mariana Trench lives and a huge variety of shellfish, which somehow mysteriously managed to keep its shell even at a pressure of a thousand atmospheres. In addition to the presence of this unique property, deep-sea inhabitants can boast the ability to convert them to deadly hydrogen sulfide in a perfectly safe protein that allows clams to survive in the most extreme conditions.

It is well known that the pollution of the ocean not only affects the life of marine life and coral reefs, calling into question the survival of even resistant to ecosystem changes, it affects everyone. Thus, pollution of ocean water can cause the penetration of toxins in seafood, significantly reduce the economic benefits of a beach holiday and business tourism, as well as adversely affect the development of the coastal countries. Finding Vescovo Victor in this case only confirms the presence of the problem, becoming a global ubiquitous.
