Ocean depths turned into "bins" for plastic waste

Plastic waste is highly pollutingenvironment, and this process is very difficult to stop. Researchers from the University of Newcastle in the UK found that non-decomposing debris lies not only on the surface of the Earth but also in the depths of the ocean. Not only does garbage simply accumulate at the bottom, it also gets into the digestive system of the inhabitants of the depths. The discovery is very alerted to researchers, as plastic waste has already caused the death of many sea turtles and even huge whales.

The study was conducted in the waters of Japan,Kermadedek and other points of the planet where there are underwater crevices thousands of meters deep. With the help of sampling equipment, scientists have raised many small inhabitants of the depths to the surface. They selected 90 animals and checked their digestive system for plastic. It is noteworthy that they checked the end parts of the digestive tract to exclude recent ingestion on the way to the surface.

Plastic was found in the guts of 72% of the animals - thanthe deeper they inhabit, the more trash they swallow. For example, in the Challenger Void with a depth of 10,890 meters, plastic was found in 100% of living beings. The most common garbage was cellulose fibers, which are actively used in clothing. The researchers also found nylon, polyethylene and polyamide.

The researchers concluded that the ocean depthsare the end point for plastic waste that people throw away - 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 is removed by tides. Ultimately, all waste is at the bottom of the oceans.

Unfortunately, mankind is still doing poorlywith a decrease in the amount of discarded plastic. A 2017 study showed that since the 1950s, people have produced 8.3 billion tons of plastic, and 6.3 billion of this mass has been released into the environment.
