Plastic waste severely polluted the environment, and this process is very difficult to stop. Researchers from Newcastle University in the UK found that non-degradable garbage is not only on the surface of the Earth, but in the depths of the ocean. Moreover, the debris simply accumulates at the bottom, so he still gets in the digestive system of animals. The opening is very alarmed researchers, as plastic wastes have already caused the deaths of many sea turtles and even large whales.
The study was conducted in the waters of Japan, Kermadec and other parts of the world where there are underwater crevices to a depth of thousands of meters. With the help of equipment for sampling, scientists brought to the surface the many small inhabitants of the deep. They took 90 animals and checked their digestive system for plastic. It is noteworthy that they tested the last part of the digestive tract to exclude recent ingestion on the way to the surface.
Plastic has been found in the guts of 72% of the animals — the deeper they live, the more garbage they swallow. For example, in the Abyss of the Challenger deep 10 890 metres of plastic was found in 100% of living beings. The most common litter were cellulose fibers, which are widely used in clothing. The researchers also found nylon, polyethylene and polyamide.
The researchers concluded that ocean depths are the final place to throw people of plastic waste — they have nowhere else to go. According to marine scientist Alan Jamieson, debris from the river can be washed away with clean water, and mud from the coastlines cleaned by the tides. Ultimately, all waste be at the bottom of the oceans.
Unfortunately, humanity doesn’t cope with the decrease in the number of discarded plastic. The study of 2017 showed that since 1950, years people make 8,3 billion tons of plastic, and 6.3 billion of this mass was released into the environment.
