ALL THE OCEANS HAVE PLASTIC DEBRIS ON THEIR SURFACE

The Malaspina Expedition, led by the Spanish National Research Council, has demonstrated that there are five large accumulations of plastic debris in the open ocean that match with the five major twists of oceanic surface water circulation. In addition to the known accumulation of plastic waste in the North Pacific, there are similar accumulations in the central North Atlantic, the South Pacific, the South Atlantic and the Indian Ocean.

The study concludes that 88% of the ocean surface contains microplastic.

According to the study authors, the major residues found are polyethylene and polypropylene, polymers used in the manufacture of everyday products like bags, food and beverage containers, kitchen utensils and toys, among others.

These microplastics have an influence on the behavior and the food chain of marine organisms. On one hand, the tiny plastic fragments often accumulate contaminants that, if swallowed, can be passed to organisms during digestion; without forgetting the gastrointestinal obstructions, which are another of the most common problems with this type of waste. On the other hand, the abundance of floating plastic fragments allows many small organisms to sail on them and colonize places they could not access to previously. But probably, most of the impacts taking place due to plastic pollution in the oceans are not yet known
