Plastic pollution deteriorates as research shows that 15% MORE single-use bottles are washed down every year since the 1980s on a remote beach in the Atlantic Ocean
- Experts studied the garbage on a beach on the inaccessible island of the South Atlantic
- Single-use plastic bottles were the most common form of debris, they found
- Most dated bottles were made within two years of being landed
- Bottles on the coast now mainly come from Asia, rather than from South America
- The team believes that this shift reflects an increase in waste dumped by ships
The amount of plastic waste on an uninhabited island in the South Atlantic Ocean is deteriorating, with 15 percent more bottles on land every year since the 1980s.
Researchers compared polls on the remote beach from the 1980s with those they conducted in 2009 and 2018.
Single-use plastic bottles were the most common form of debris, most of which were manufactured within two years of being washed up.
While most of the bottles washed ashore came from South America in the 1980s, the team discovered that most are now from Asia after being dumped from ships.

The amount of plastic waste on an uninhabited island in the South Atlantic Ocean is deteriorating, with 15 percent more bottles on land every year since the 1980s
Ornithologist Peter Ryan from the University of Cape Town and colleagues studied plastic bottles and containers washed up on the west coast of the remote and uninhabited Inaccessible island in the central South Atlantic.
The island had previously been investigated for litter in the 1980s – with the researchers who added their analyzes from 2009, when they found 3,515 pieces of washed-up jetsam, and 2018, when they reported that they were studying 8,084 pieces of rubble.
The researchers discovered that polyethylene terephthalate – or PET – drinking bottles were the most ubiquitous form of debris.
& # 39; Plastic beverage bottles show the fastest growth, with 15 percent a year compared to 7 percent a year for other types of debris, ”the researchers wrote.
The team analyzed the washed up waste for production data.
Most bottles on the coastline date from within two years of being washed ashore.
However, the oldest piece of waste that the researchers found in 2018 came from a high-density polyethylene canister that was produced in 1971.
& # 39; By 2018, Asian bottles consisted of 73 percent of cumulated and 83 percent of newly arrived bottles, most of which were made in China & # 39 ;, the team wrote. Pictured, 500 ml water bottles made by the Chinese brand Master Kong, the most common in 2018, sorted by age
Researchers compared polls on the remote beach from the 1980s with those they conducted in 2009 and 2018
In the research conducted in the 1980s, about two-thirds of the plastic bottles that washed ashore were on Inaccessible Island from South America.
& # 39; By 2009, Asia had surpassed South America as the main source of bottles, and by 2018, Asian bottles consisted of 73% accumulated and 83% newly arrived bottles, most of which were made in China & # 39 ;, the researchers wrote.
& # 39; The rapid growth of Asian rubble, mainly from China, in combination with the recent production of these items, indicates that ships are responsible for most bottles floating in the central South Atlantic Ocean. & # 39;
According to the researchers, this disposal activity is contrary to the International Convention for the Prevention of Pollution from Ships.
The full findings of the study were published in the Proceedings of the National Academy of Sciences.

WHAT DOES DEEP-SEA RECEIVE DEBRIS DATABASE ON OCEAN PLASTIC POLLUTION?
Plastic pollution is a pest that destroys the surface of our planet. Now the polluting polymer sinks to the bottom of the ocean.
The deepest part of the ocean is in the Mariana Trench, located in the western Pacific Ocean, east of the Mariana Islands. It extends to almost 36,000 feet (11,000 meters) below the surface.
One plastic bag was found 35,754 feet (10,898 meters) below the surface in this region, the deepest known piece of man-made pollution in the world. This single-use piece of plastic was found deeper than 33 Eiffel towers, with the tip laid to the base.
While plastic pollution is sinking rapidly, it is also spreading further to the middle of the oceans. A piece of plastic was found more than 620 miles (1000 km) from the nearest coast – that is beyond the length of France.
The Japan's Agency for Marine-Earth Science and Technology (Jamstec) launched the Global Oceanographic Data Center (Godac) for public use in March 2017.
This database contains the data of 5,010 different dives. Of all these different dives, 3,425 man-made rubble items were counted.
More than 33 percent of the rubble was macroplastic followed by metal (26 percent), rubber (1.8 percent), fishing equipment (1.7 percent), glass (1.4 percent), cloth / paper / wood (1.3 percent) and & # 39; other & # 39; anthropogenic products (35 percent).
It was also discovered that 89 percent of all waste found was designed for single use. This is defined as plastic bags, bottles and packaging. The deeper the research looked, the greater the amount of plastic they found.
Of all man-made items found deeper than 20,000 feet (6,000 meters), the ratios increased to 52 percent for macro-plastic and 92 percent for single-use plastic.
The direct damage that this has caused to the ecosystem and the environment can be clearly seen, as deep-sea organisms were observed in the 17 percent of the images of plastic waste taken by the study.
