Plastic does not decompose completely, and its microscopic fibers enter the food chain of marine life, causing more and more damages to the world ocean.
In the Northern hemisphere, the debris falls into the ocean mainly from the ground. In the South things are different, find out the latest Moore's expedition to the Islands of Passover and Robinson Crusoe. She is allowed to "close a gaping hole" in our knowledge, says oceanographer Eric van Sabel, Utrecht University. "In the ocean, almost no areas not contaminated with plastic. It's scary".
Captain Moore, just returned from those latitudes with samples and tests, says that in contrast to the Northern spot in the South main source of pollution — fishing vessels.
The extent of the problem are impressive: the area of the subtropical cycles comparable to the entire earth, and now she is rapidly "colonized our garbage," says the captain. The mission of the Moore expedition is to collect samples of the micro-plastic and to clarify the volumes, areas, concentrations and origins, to reveal the global scale of the problem.
Another task is to assess the impacts of pollution on the fauna of the South Pacific ocean. The largest family of deep-sea fish — myctophobia constitute an important part of the diet of whales, squid, and penguins. And if it is glowing anchovies, as they are known, will swallow a lot of the micro-plastic, the consequences can produce a Domino effect throughout the food chain, warn scientists.
