Serious marine pollution! 11000 meter deep-sea creatures actually eat plastic
according to the British Daily Mail on November 16, recently, scientists found plastic fibers in the stomach of the deepest creatures in the ocean for the first time. Researchers found that crustaceans in the Pacific Ocean nearly 7 miles (about 11000 meters) deep eat plastic. This discovery shows that the deep ocean is also polluted by man-made garbage
Dr. Alan Jamieson of the University of Newcastle has surprising research results. He said: "the deep sea is like a terminal radiator, in which there are organisms that adapt to the low food environment. In order to avoid affecting the accuracy of experimental results, research shows that man-made micro fibers have reached the peak in such an ecosystem, and marine organisms have to ingest plastic fibers in such a low nutritional environment."
the 90 crustacean samples used for the study were taken from the ultra deep trench across the Pacific Ocean, including Mariana, Japan, the New Hebrides and the kmadek trench. Sampling 6.7 miles from the bottom of the Mariana Trench in the Pacific Ocean found that almost every organism swallowed micro fragments such as nylon, polyethylene and polyvinyl chloride
researchers first discovered toxic chemicals, which were banned in the 1970s. But in February, researchers realized that marine pollution could be spread through plastic debris deep in the ocean
Dr. Jamison said: "When we realize that man-made fibers can enter the stomach of crustaceans through adipose tissue, we need to do more work to control pollution. Because even when marine garbage is cleaned up, in some cases, plastic fiber fragments have entered the stomach of marine organisms. In addition, we feel that by doing this research, we need to make a statement on human heritage, including water leakage experiment: in the New Hebrides In the trench, the proportion of marine organisms eating plastic has increased from 50% to almost 100%
the research team used deep-sea detectors to freely fall to the seabed for monitoring and sampling tasks. It is estimated that at present, 300 million tons of plastic waste are floating in the ocean, and more than 250000 tons of 5trillion plastic fragments are floating on the water. Dr. Jamison said, "these observation records are the most in-depth research records on the edible plastic fiber fragments of marine organisms. At the same time, they also show that other marine ecosystems may be polluted by fiber fragments. The experimental machine we produce should ensure the quality of self-adhesive."
