Birds help to determine the level of contamination of the Pacific Ocean Facts
University of British Columbia found that the level of plastic pollution in the north-western part of the Pacific Ocean off the coast of North America has almost reached the performance of the North Sea. These data were obtained after an internal investigation of the stomach contents of birds types of "silly" (Latin Fulmarus), living in the Canadian province of British Columbia and the U.S. states of Washington and Oregon.
This type was chosen by scientists as a halo bird is quite wide, which would create a more clear picture of pollution North Pacific. Besides, fulmars feed only in the sea. Comparing the new data with the materials of the previous analysis, conducted in 1980, environmentalists were amazed at how much more plastic particles began to appear in the food chain of birds, and thus in sea water.
Of the 67 animals in 92.5% of cases were found in the form of plastic waste candy wrappers, pieces of pieces of cord or polystyrene foam. The average number of fragments per animal was 36.8, the total weight of the seized plastic carcasses was 0.385 g at the bird, which is 5% of the average body weight of 2.25 kg, as if the human stomach were 50 grams of plastic. In one animal, was as much as 454 grams in the stomach.
"GOLD", found in the stomach of one of the birds
Until recently, the sea water off the northwest coast of North America was not considered as a zone of high anxiety, despite the relatively short distance to the Great quiet-ocean garbage patches. Now, however, an urgent need to develop and implement monitoring technology methods to protect the fauna of the region and the purification of water from pollution.
