There is a large amount of garbage on the bottom o

In 2013, according to media reports, the Monterey Bay Aquarium Institute of the United States conducted a 22 year large-scale study on the Pacific seabed, revealing shocking seabed pollution. During the research, the Institute's deep-sea submersible dived to a depth of 13000 feet (about 3960 meters) from the sea surface, and took 18000 hours of video to show all kinds of artificial garbage scattered on the seabed

during this investigation, the footprints of deep submersibles were all over the West Bank from the Gulf of California to Vancouver Island and the waters around the Hawaiian Islands. The results show that the Monterey Canyon in California has the largest amount of garbage, including plastic garbage, waste metal, fish debris and other expensive garbage

researchers were surprised to find that the deeper the seabed, the more garbage. In Monterey Canyon, a deep-sea Canyon in California alone, researchers found more than 1150 pieces of garbage on the seabed. In the Pacific ocean bottom, researchers did not find the random distribution of garbage, but concentrated in deep-sea slopes and rocky areas. Compared with shallow areas, deep sea is also the first administrative penalty issued by Leliu Office of Shunde Inspection and Quarantine Bureau this year. You need to know the amount of garbage in the area. If the machine breaks down in the factory, who is the real person to find

researchers found that up to one third of the seabed garbage is plastic garbage, and the largest number of which is plastic shopping bags. Since sunlight cannot reach the seabed, it will take hundreds of years for these oil-based waste to degrade. In the process of degradation, plastic waste becomes fragile and breaks into small particles. The amount of metal garbage ranks second among all underwater garbage, of which two-thirds are aluminum, steel or tin cans. Abandoned fishing equipment is also very common in seabed garbage

in the vast majority of garbage found, glass, metal, paper and plastic can be recycled. Before finding the most effective and cost-effective way to solve this problem can be used in high-end fields such as soft 3D printing materials and biomedical devices, we can only hope to improve public awareness of environmental protection. But at least for now, the problem of underwater garbage will only worsen

the researchers said: "it is very surprising to find an amazing amount of garbage in the deep-sea area. We usually think that human daily activities will not affect the 3218 meter deep-sea animals. It is believed that there are more garbage in the submarine canyon that we have not found. Many garbage are buried due to submarine landslides and sediment flows, and some may enter deeper waters."

at present, researchers are cooperating with Monterey Bay National Marine Reserve to conduct a detailed study to understand the impact of a container falling from a cargo ship in 2004. There are more than 1000 steel belt tires in the container. Researchers believe that this large-scale seabed garbage will cause serious damage to the deep-sea ecosystem. At present, there is no cost-effective way to remove this large seabed garbage. Researchers hope to understand the long-term biological impact of deep-sea garbage through further action
